Abiogenesis Presented As Matter of Fact by NASA Speaker 11/30/2001 Abiogenesis, the belief that life arose spontaneously
from inanimate matter, once thought disproved by Pasteur, is alive
and well in NASA. In public lectures at JPL and Pasadena
City College entitled The Search for Earth-Like Planets,
webcast to the world on the JPL Website,
Dr. Charles Beichman explained the two-fold thrust of
NASAs Origins program:
(1) Where do we come from?, and (2) Are we alone? Dr. Beichman
provided four fundamental ideas that he says have changed scientists
thinking into optimism that life will be found in space:
- The necessary ingredients of life are widespread in the universe:
the laws of physics are the same everywhere, and the elements and
molecules common to life are ubiquitous.
- Planets are a common, natural outcome of star formation.
- Life on earth can inhabit harsh environments. So-called
extremophiles have been found in boiling hot springs and
buried in Antarctic ice and around deep sea vents.
- Life can affect a planet on a global scale, allowing us to infer the
presence of life by studying the spectra from atmospheric gases on
extrasolar planets.
(Just this week, the Hubble Space Telescope made the first direct measurement of the
atmosphere of a planet around another star.)
By implication, life, which we have not discovered yet, must as common
a property in the universe as the planets and ingredients we do see.
Dr. Beichman went on to discuss how JPL scientists are involved in detecting
extrasolar planets, and some day may be able to image earthlike planets
around other stars and characterize the gases in their atmospheres
thereby gaining clues whether life exists around other stars.
These kinds of presentations are so common
in NASA circles they are not news, but it bears repeating that abiogenesis
should be a highly contested and controversial belief. Yet
no one in the audience offered the slightest objection to what was
claimed. Is it really possible to get from hydrogen to the
Hallelujah Chorus by the continuous operation of undirected natural
laws? Or are there major discontinuities, unbridgeable by
naturalistic presuppositions? Is life an accident that happened
here, and happens all over where you have the ingredients present?
If so, then what does that mean for abstract concepts like truth, knowledge,
wisdom, and morals?
Dr. Beichman would, of course, regard these questions
as off the point, claiming he is not talking about religion, but science;
individuals can believe whatever they want, but he is just there to
address the scientific matters of
evidence, detection techniques, spectra, and molecules. But the
clear implication of these kinds of presentations is that life is a
natural by-product of unguided, undirected, impersonal, natural forces;
God is superfluous, as far as biology is concerned. Any logical
person must realize that abiogenesis is deadly to belief in God; at best,
it pushes Him off to the beginning as a distant First Cause, uninvolved
in a mechanistic universe that evolves of its own accord.
Yet the scientific evidence militates against
abiogenesis! Even the simplest life is tremendously more complex
than nonliving molecules. The so-called common ingredients of life
are no closer to life than scattered Scrabble letters are to an
encyclopedia. Its the way these ingredients are organized
into autonomous, growing, reproducing systems that defies all naturalistic
explanation; and on this point, astrobiologists are strangely silent.
Dr. Beichman admitted in the Q&A session
that chirality (handedness) of molecules might
be a biomarker an
indicator of life yet getting even one single-handed chain of even
10 units by chance is prohibitively improbable,
and natural selection cant help.
His Fundamental Idea #3 (Life on earth can inhabit harsh environments),
so frequently touted by astrobiologists, begs the question of whether
life can form spontaneously in the first place harsh environment
or not. Under the most favorable conditions imaginable, abiogenesis
is ruled out of the game by the laws of
probability. At every upward step, furthermore, evolution is
blocked and tackled by the laws of thermodynamics. And if
abiogenesis is true, it renders truth and knowledge meaningless and
that includes science. Remember how
PBS said that our noblest
enterprises are just sex urges?
Surely Dr. Beichman would want his thoughts to be taken more seriously than
to be viewed as pawns of selfish genes that for some reason want to
propagate themselves endlessly (Why? Who cares?). If we are mere
particles in motion, then science is dead; lets close down the Lab,
eat, drink and party, for tomorrow we die.
The bottom line is, abiogenesis should be laughed off
the stage. It is ridiculous on scientific, philosophical, and
logical grounds. Its implications for theology and morals are
like poison. Why do these NASA speakers get away with spouting
nonsense, year after year, with nobody calling them on the carpet for
it?
Scepticism. I shall here write my thoughts without order, and not perhaps in unintentional confusion; that is true order, which will always indicate my object by its very disorder. I should do too much honour to my subject, if I treated it with order, since I want to show that it is incapable of it. Pascal,
Pensées.

Article 11/29/2001: More Baloney Detecting: How to Draw Boundaries
Between Science and Pseudoscience, Part II, by Michael Shermer,
Scientific
American. The editor/publisher of Skeptic magazine continues
his 10 principles of Baloney Detection he began in
Part I last month.
Lets continue analyzing Darwinism
by Shermers criteria.
- Does the preponderance of evidence point to the claimants
conclusion or to a different one?
The theory of evolution, for example, is proved through a
convergence of evidence from a number of independent lines of
inquiry. No one fossil, no one piece of biological or
paleontological evidence has evolution written on it;
instead tens of thousands of evidentiary bits add up to a story of the
evolution of life. Creationists conveniently ignore this
confluence, focusing instead on trivial anomalies or
currently unexplained phenomena in the history of life. [emphasis added].
Here Shermer takes the creationists head-on, but his metrics are
purely arbitrary and his judgments subjective. If you are a
regular reader of
Creation-Evolution Headlines, you may have come to the exact
opposite conclusion: that evolution is a collection of
just-so stories
pieced together with the meagerest evidence (example: Jared
Diamonds paper two days ago), while ignoring major and
substantive problems: evidential, theoretical, logical and philosophical. Keith Wansers quote (top of this page) bears repeating at this point.
Shermer himself conveniently ignores the
ongoing work of the Creation Research
Society, the Institute for Creation
Research, the Creation
Technical Journal, and other organizations who have been doing scholarly
research for decades, not just picking at trivial anomalies
in evolutionary theory.
Is the claimant employing the accepted rules of reason and tools of
research, or have these been abandoned in favor of others that lead to
the desired conclusion?
Over and over here in these pages, we have shown
evolutionists stuffing shreds of evidence into their preconceived
notions. Look at the monstrous leap of faith in the
Nov 26 story (quote, in commentary), for
instance. See more
examples evolutionists have used in our Baloney
Detector. Add to that the complaint by evolutionists themselves
that evolution is untestable
and unfalsifiable. So Darwinism fails this criterion, too.
(Down to an F- already; do we need to go on?)
Is the claimant providing an explanation for the observed
phenomena or merely denying the existing explanation?
Shermer calls this a classic debate strategy and declares
it unacceptable in science, yet his criterion commits two
logical
fallacies: (a) Shifting the Burden of Proof, in which he asserts that
no one has a right to criticize evolution unless he can replace it
with something better: This is the classic debate strategy.
(b) Best-In-Field Fallacy, in which an evolutionist feels justified in
coming up with some just-so story, no matter how weak, rather than
no naturalistic explanation at all. This is the stratagem that is
unacceptable in science; saying I dont know would be
an improvement.
In this paragraph, Shermer targets Intelligent
Design theory, but knocks down a straw man, and shows that he neither
recognizes his own bias nor understands
what ID theorists are saying. The reader is referred to
Access Research Networks
ID FAQ page, and to
articles by William
Dembski.
If the claimant proffers a new explanation, does it account for as
many phenomena as the old explanation did?
This is usually a good principle in science (such as in heliocentrism
over geocentrism), but it does not always apply, especially when the
phenomena are not one-time prehistoric events that are not repeatable and
testable, such as in big-bang inflation theory and the origin of life.
Early Darwinism seemed to account for many things,
until critics realized
that natural selection was a tautology that was stating the obvious:
survivors survive, and the fit are fitter than the unfit. This shows
that it is possible for a theory to explain everything and yet really
explain nothing at all. A rose is a rose; is it true? Yes.
Is it obvious? Yes. Is it useful? No.
The late 20th centurys mushrooming
pace of discoveries in biochemistry (DNA, protein structure, molecular
motors) are straining the old paradigm to the breaking point.
Today, evolutionists are just assuming evolution can account for
these things somehow, but failing to explain how they could things outside
the arena of natural selection, and things so
improbable they would never happen naturally in a billion universes.
Early modern science (and
excellent science at that) was built on a
philosophical foundation of intelligent design. Since
naturalism has shown itself bankrupt at providing explanations for
specified complexity, and even proffers explanations that are contrary
to known laws, it is time to
re-evaluate the suitability of naturalism as a presupposition for science.
Do the claimants personal beliefs and biases drive the
conclusions, or vice versa?
A logical positivist is someone who sees science as an objective, neutral,
unbiased means for arriving at absolute truth. Many modern scientists,
unfortunately, do not realize this premise is guilty of the
Self-Referential Fallacy.
They cannot understand that philosophical naturalism is a belief system,
a faith, even a religion. Some admit it partly, but think that somehow
science is better than any other approach to explaining anything
and everything (even the origin of the universe, life and man).
But even this is a value judgment not determined empirically; it is merely
a preference. Asserting that, Well, science has given us
cell phones and religion hasnt commits other
fallacies, like extrapolation, equivocation, association, and glittering
generalities; it tries to link verifiable physics with untestable,
unverifiable stories about the unobservable past. Whats
Darwin got to do with it?
The bottom line
is that all people are biased, even scientists. Some biases can be
mitigated by repeatability, testability, and honest debate.
We have shown that Darwinian storytelling
survives best in a vacuum insulated from criticism
and is inherently untestable.
Shermer adds praise for
peer review, as if it reduces bias, but just last week we reported an
angry complaint by three scientists in
Nature that peer review is like a religious rite, that it is
unnecessary, a colossal waste of time, stifling to innovation, intolerant of
opinions outside the party line, an obstacle to good scientific work, and
cultivator of corruption.
We have also shown numerous papers
that passed peer review yet claim patently illogical things,
perfectly permissible as long as they fit in with Darwinian philosophy.
Now that you have passed this short course in baloney
detecting, try
your hand at Shermers concluding statements. Grade him on
objectivity, clear thinking, and integrity:
Yet there is a solution: science deals in fuzzy fractions of
certainties and uncertainties, where evolution and big bang cosmology
may be assigned a 0.9 probability of being true, and creationism and
UFOs a 0.1 probability of being true. In between are borderland
claims: we might assign superstring theory a 0.7 and cryonics a 0.2. In
all cases, we remain open-minded and flexible, willing to reconsider
our assessments as new evidence arises. This is, undeniably, what makes
science so fleeting and frustrating to many people; it is, at the same
time, what makes science the most glorious product of the human mind.

Navy Looks to Lobster for Smelling Technology 11/29/2001
Lobsters have noses, too; small organs called aesthetacs on the tips
of their antennae that sweep through the water. If you have watched
lobsters carefully, you may have noticed that the downstroke is faster
than the upstroke. There may be a reason for this, and
scientists funded by the Office of Naval Research are trying to find
out, says
EurekAlert. By studying lobsters, the Navy
hopes to find better ways to sniff out underwater explosives.
The team built a robotic lobster on a real lobster exoskeleton, but
outfitted it with their own steel antennae with electronic sensors and tried to
mimic the motion of a live lobster. They found that the twitching
motion apparently provides the lobster with a quick high-resolution map
of the odor plume coming its way,
and the slow upstroke may give it time to analyze the data without disturbing
the pattern set up on the sensors. The beginning of the next downstroke
resets the sensors, and provides an update on the source of the odor.
The report states with admiration,
For a lobster living on the ocean floor, the chemical trails left
by prey, predators, mates and competitors must make a confusing
tangle each filament of odor intertwining with the others until
discovering the source of any one of them starts to seem as impossible
as untangling a ball of liquid yarn. But somehow the lobster does
it.
How many times have we seen human engineers
getting their inspiration from designs in nature? Notice how what looks
on casual observation like just a nervous twitching by the lobster
actually has a very real function. Human robotic engineering is
making us aware of the robots all around us that are light-years ahead
of us in design.

Scientists Take Motion Pictures of Brain Forming Memories 11/29/2001
Scientists at the
University
of California, San Diego
believe they have found the Holy Grail of neurobiology by
taking the first motion pictures of the brain
forming short-term and long-term memories. Using new imaging
techniques that do not damage cells, researchers have been able to
watch neurons form temporary synapses (connections) that last about 5-10
minutes, which might reflect the stimuli that produce short-term memory,
and permanent connections after four or more stimulations per hour,
that might reflect long-term memory. Once you take an
axon and form two new connections, those connections are very stable
and theres no reason to believe theyll go away,
says Dr. Michael Colicos, one of the team members; Thats
the kind of change one would envision lasting a whole lifetime.
To achieve this imaging, the team created glowing actin filaments that
could be watched as they formed bridges to other neurons, and found a new
way to stimulate neurons without harming them. The press release
includes three videos of the synapses in action. It was a delicate
and painstaking task: there are a billion synapses in a cubic centimeter
of brain tissue.
This story is truly amazing for its
achievement, and it also raises many fascinating speculations about
the relationship of our soul to our body. There are many trillions
of possible connections of neurons, but can we really reduce the vividness
of memory to synapses? Think of your favorite piece of music right
now; you can undoubtedly play it back perfectly in your head, and even
fast-forward it or embellish it. How
many synapses does that require? What tells the brain to find
the right synapses, and play it back in the right sequence?
Is the soul merely the sum total of brain cells? Or could it be
that the synapses act like RAM and a hard drive
for a soul that is transcendent of the material? It would seem
that inanimate
matter can store, but not perceive, in a fashion similar to
the way computer memories store the intelligent design of the programmer.
Has the Creator given us hi-tech storage devices for the soul? If you
think so, why not tell God right now, Thanks for the memories.

Physics Still Has Areas of Soft Science 11/28/2001
Many think of physics as hard science, but two recent stories in
Nature
Science Update indicate we still have much to learn.
Regarding quantum mechanics,
Phillip
Ball writes that Einsteins hidden variables
may exist after all. Einstein believe that there were unknown
variables that explained weird quantum experiments that appeared to
invoke a spooky action at a distance. Now, two physicists at
the University of Illinois believe that these hidden variables, whatever
they are, cannot be ruled out, and that there may be another layer to
reality.
In another story, scientists cannot explain how a
large black hole
got into a binary system. Object GRS1915+105, at 14 solar masses,
is too large to have formed within a close binary relationship.
Either their theories about X-ray emission or black hole spin or
black hole formation are wrong, or all the above.
Some physicists and popularizers
have used the quirkiness of quantum mechanics, especially the
Copenhagen Interpretation (which basically allows for contradictory
states to be simultaneously true and reality to be dependent on the
observer), to promote new-age religion. We need to be honest
enough to plead ignorance before jumping to conclusions, as Einstein
did, and understand the limitations of science.

Why Were Dinosaurs So Large? 11/27/2001
Jared Diamond tries to find the laws of body size in a paper in the
Proceedings
of the National Academy of Sciences. In Dinosaurs,
dragons, and dwarfs: The evolution of maximal body size, he
investigates the relation of land area, food availability, and other
factors with the body size of the largest animals. He finds a
general correlation between land area and body mass of the top species.
Some misfits
in certain areas and times (too big or small for their habitat) are
alleged to evolve to fit over time, but there are anomalies: why did the
dinosaurs grow so large? They dont fit the equation and
remain unexplained. For summary, see
Scientific American.
Anti-creationist Jared Diamond is at it
again, adding Darwinist fluff to the scientific journals, but accomplishes
nothing. He just observes the obvious, that some animals are big
and others arent, but fails to find a universal law that relates
them to all the environmental variables, and more importantly, fails to
come up with a mechanism for how one creature can evolve into another.
This paper contains a few interesting observations, but ends up with
more questions than answers. Nothing here demonstrates Darwinian
evolution any more than an explanation based on biogeographical dispersion
after a Noachian flood.
There are way too many variables here, and the data are not specific
enough to formulate a law of nature; there will always be exceptions.
If you have a lot of food, you might grow big; that is not evolution.

How the Deaf Hear Music 11/27/2001
A radiologist at the University of
Washington
performed brain scans on deaf students and those with normal hearing,
according to EurekAlert,
and found that the part of the brain that normally only responds
to sounds (the auditory cortex) responds when the deaf students
felt vibrations on their hands. Apparently, the brain
compensates for hearing loss by rewiring itself. Dr. Dean
Shibata, who uses functional magnetic resonance imaging to do
the research, explains:
The brain is incredibly adaptable.
In someone who is deaf, the young brain takes advantage of valuable
real estate in the brain by processing vibrations in the part of the
brain that would otherwise be used to process sound....
These findings illustrate how altered experience can affect brain
organization. It was once thought that brains were just
hard-wired at birth, and particular areas of the brain always did one
function, no matter what else happened. It turns out that, fortunately,
our genes do not directly dictate the wiring of our brains. Our genes
do provide a developmental strategy - all the parts of the brain will
be used to maximal efficiency.
As a consequence, deaf people can enjoy concerts and even become
performers. At the National Technical Institute for the Deaf
in Rochester, for instance, audience members are provided with balloons
with they touch with their fingertips to feel the vibrations of the
music. Dr. Shibata says, Vibrational information has essentially
the same features as sound information - so it makes sense that in the deaf,
one modality may replace the other modality in the same processing area of
the brain. Its the nature of the information, not the
modality of the information, that seems to be important to the
developing brain.
The adaptability of the human body is amazing. With Gods
design, no loss is a total loss. We would like to know the impressions
any deaf readers have of music and other vibrational input; can you actually
sense the different instruments in the orchestra or band? Please
send us your comments (use the Feedback link on the right column).

Why Doesnt the Octopus Tie Itself in Knots? 11/27/2001
Robot designers would like to know. Boneless and brainless,
the lowly octopus is able to maintain control of its eight arms
without them getting hopelessly tangled up. According to
EurekAlert,
the octopus uses completed staff work and distributed processing;
the general (brain) gives the orders, and the troops (arms) carry
them out. How the octopus does this is under study by researchers
funded by the Office
of Naval Research.
But now ask the beasts, and they will teach you;
And the birds of the air, and they will tell you;
Or speak to the earth, and it will teach you;
And the fish of the sea will explain to you.

In whose hand is the life of every living thing,
And the breath of all mankind? (Job 12:7-10).

Search for Life Brings in the Funding for NASA 11/26/2001
Bruce Moomaw reports in
SpaceDaily.com
on a gathering of planetary scientists this month discussing how best to
set priorities for NASAs planetary exploration program. Of the
top contenders,
...astrobiology received much attention as the main
motivator for funding Solar System exploration a situation that
can provoke sharp feelings among scientists dealing with non-astrobiologically
focused research.
As a way of attracting support from the general public and thus
funding the search for life on other worlds has undeniable
power. After all, most people find the idea of alien life forms
(even primitive ones) far more interesting as a subject than rocks or
gases or magnetic phenomena.
As a pacifier for those scientists outside this emphasis, two astrobiologists
assured them that astrobiology is a very sweeping
term than encompasses many different scientific pursuits.
So, the search for life is the sexy spin
for NASA that gets the public interested and the money flowing.
They cant lose, because even if they dont find it, they
just havent looked hard enough. And no matter if they
never find it: materialistic evolution will be vindicated! Consider this
incredible statement of faith: Conversely, if other worlds
turn out to have been habitable for long periods in their history but
life did NOT develop there, it will be a strong piece of evidence
that life on our own world is the result of a long-shot stroke of
pure biochemical chance. [emphasis added]. Now thats
the kind of believer Las Vegas likes!

Human Embryo Cell Cloned 11/26/2001

Sunburn Repair Protein Found 11/26/2001
A protein named interleukin-12, a type of cytokine, has been found to be
effective in reversing damage caused by the suns ultraviolet light.
According to Nature
Science Update, it appears to work by activating the DNA to edit out
mistakes: The protein appears to stimulate a cellular editing system
that snips damaged pieces of DNA out of the sequence, the report
states. Cells with interleukin-12 were actually able to reverse
sunburn damage. If IL-12 is this effective, other cytokines may also
be involved in DNA repair. This is probably the tip of the
iceberg, says Kenneth Kraemer of the National Institutes of Health,

Internet Nerds More Likely to Be Church-Goers 11/26/2001
According to Professor Andrew Oswald and Dr Jonathan Gardner from the
University of Warwick,
UK, the stereotype about unsociable nerds hunched over their Internet
computers finding anonymous relationships in chat rooms is wrong.
Most typically young and male, Internet surfers are sociable, educated,
affluent, more likely to belong to volunteer organizations, and 50% more
likely to go to church regularly. This conclusion comes from the
18th British Social Attitudes report, Britains most authoritative
annual survey of public attitudes.
Its hard to claim this proves anything,

Letter 11/22/2001: The Perils of Peer Review,
Nature correspondence. Three angry
scientists vociferate against the peer review process, comparing it to
a religious ritual (or worse, an inquisition):
Your News feature Peers under pressure
(Nature
413, 102-4; 2001) on the hoary old chestnut of peer
review reinforces my decades-old comparison of this
ritual to the Latin mass. Obviously many (Protestant?)
leaders, including most of the best-known scientists such
as Nobel laureates, regard peer-review as a great
hindrance to good science (the gospel?). Many excellent
journals (churches?), such as the Proceedings of the Royal
Society and Proceedings of the National Academy of
Sciences managed in my opinion very well without it for a
long time. An enormous amount of the best science has
been and is being run without benefit of this rubric, as is
the worldwide patent system.
After discussing a recent case of dishonesty caused by a scientists
efforts to hide his work from rivals during the peer review process, they
continue their tirade: Yet this is but a minor defect in the
peer-review system. The enormous waste of scientists time,
and the absolute, ineluctable bias against innovation, are its worst
offences.
And you were taught that peer review
was the guarantee of scientific objectivity. We are not here rendering
judgment on peer review, but these scientistss complaints should
be taken to heart. It is clear that many of historys
greatest scientists did their groundbreaking work
outside the peer review system.
Many creationists today complain that peer review tolerates only
naturalistic, evolutionary submissions, and that their work, no matter how
empirically sound, is systematically excluded on philosophical grounds.
How the Ameba Crawls 11/22/2001
Yale scientists have gained new insight into how cells move, reports
EurekAlert.
Theyve revealed the 3-D structure of seven proteins called the
Arp2/3 complex that assembles actin proteins into filaments, which push
the front of the cell forward. A similar process (actin polymerization)
is involved in white blood cells moving to the site of an infection, and in
neurons branching out into the million miles (more or less) of axons and
dendrites in the human brain.
Thomas Pollard of Yale, co-author of the paper in
Science,
explains how it works. Chemicals in
the environment send messages to the Arp2/3 complex, which in turn cause
it to orient the cell and move in a particular direction. He says,
Actin and Arp2/3 complex work like a peculiar motor in a car to
make the cell move forward. Rather than turning wheels, the filaments
grow like branches of a bush to push the cell forward. Arp2/3
complex is very ancient, having evolved in primitive cells well over
one billion years ago.
How can anyone look at
this amazing mechanism, call it primitive and ancient, and say it just
evolved?
Do you know any other motors that are engineered by
blind, undirected, impersonal forces? One of the characteristics that
sets life apart from nonlife is its ability to respond to stimuli
contrary to
what would happen by chemistry and physics alone.
The difference is analogous to a man climbing uphill vs a statue of a man
falling downhill. To achieve autonomous movement,
even the lowly ameba has to have plans and processes.
What Darwin did not know, modern biochemistry has revealed: each cell has a
detailed DNA code and transcription mechanism that
builds precisely-engineered proteins (the Arp2/3 complex), which in turn
assemble a motor protein (actin) at the appropriate end of a cell to
make it move. An ameba may look simple,
but the simplicity is deceiving; it moves where it wants!
Rocks do not do this.

Expert on Self-Organization Agrees Intelligent Design Has Merit 11/20/2001
In a debate 11/13 at the University of New Mexico against William Dembski,
Stuart Kauffman publicly admitted that intelligent design was a
legitimate intellectual and scientific project and that research projects
like SETI (the Search for Extraterrestrial Intelligence) couldnt
even get off the ground without it, writes Phillip Johnson in his
Weekly
Wedge Update for 11/19. Kauffman, well known as a specialist
in the theory of self-organization, did not feel I.D. was applicable to
biology, but did lay down some boundary conditions for his own
theory to work: probabilities that could well bring I.D. into the
argument as the only valid approach.
Johnson sees this as a major concession
by an evolutionist. Rather than ruling intelligent design theory
off the table by fiat, as some evolutionists do, Kauffman was courteous
and considered Dembskis arguments on their merits. Even a
local skeptics society seemed to tone down their rhetoric.

Chemists Dispute Claim of Life in Martian Meteorite 11/20/2001 Since the high-fanfare announcement of possible
microscopic evidence for fossilized life in Martian meteorite ALH 84001

eroded. Now, scientists at
Arizona
State University take the last remaining claim down another notch.
They argue that the magnetite crystals that were alleged to be the work

NASA was selective in its observations, ignoring 73% of the other magnetite
crystals in the rock.

Cholesterol Builds Better Brains 11/20/2001
90% percent of your brain is composed of glia cells, not involved in
thinking like the neurons, so less interesting to researchers.
But now neuroscientists have found that they secrete a molecule with
a bad rap cholesterol that is essential for the formation
of synapses (connections) between neurons. Cholesterol may clog
arteries, but it is vital in cell membranes. The team had two
big surprises: first that cholesterol was so essential to synapse
formation, and second that the lowly glia cells produce this vital

How Did Cell Nucleus Evolve? Nobody Knows 11/19/2001 In a new Explore feature,
Scientific
American investigates current thinking about how eukaryotic cells
evolved a nucleus, and concludes that no theory currently explains all
the facts. Some think that early cells developed a symbiotic
relationship with bacteria or archaea, but the nucleus has unique features
that are not present in either assumed progenitor. Every theory has
serious objections. One biochemist admits, We really probably
dont have any idea what happened. It does seem like, whatever
happened, it was probably very complicated and not very sensible.
Not sensible to naturalistic philosophy,
that is. This is what happens when scientists feel obligated to
explain life by materialistic means. This article makes a good case
study for how a theory can sound plausible at first glance, until nasty

Wonders Within 11/19/2001: Why dont our
digestive acids corrode our stomach linings?
Scientific
American describes the complicated chemistry that your stomach
performs to keep its hot potato hydrochloric acid, HCl from
burning itself. Biologist William K. Purves of Harvey Mudd College
explains why the stomach needs the acid in the first place:
In summary, HCl
in the stomach lumen accomplishes four things.
It helps break down ingested tissues for attack by digestive enzymes;
it provides the correct pH for the action of those enzymes; it converts
a catalytically inactive proenzyme to an active enzyme (as we just saw);
and it destroys invading microorganisms in the stomach contents.
The proenzyme he refers to is like a chain saw with a
blade guard; if let
loose in the cell that manufactures it, it would be dangerous.
After release into the stomach, the HCl dissolves away the
blade guard so that the chain saw goes to work on the food, not on the
stomach. Later, as the food moves on to the next processing station (the
small intestine), the HCl is no longer needed, so the pancreas neutralizes
the caustic acid which has ten times the acidity of lemon juice.

Your Non-Essential Genes Protect You 11/23/2001
Scientists at the
National Institutes
of Health have been scanning through 3,760 non-essential genes in yeast
and finding them not so useless after all. So far, they have found
107 that apparently protect from radiation and toxins in the environment.
Non-essential genes are ones the organism can live without grow and
develop into maturity without apparent harm. When danger lurks,
however, these genes are switched on and provide protection. Since
these genes in yeast and mammals are similar, they expect similar protection
is afforded humans by these non-essential genes.

Complexity of Biological Clocks Baffles Researchers 11/16/2001
The entire issue of the November 29 Philosophical Transactions: Biological Sciences of the
Royal Society of London is
devoted to Complex Clocks. Some statements
from Fred Kipperts introduction indicate that molecular biologists,
reductionist by vocation, have their hands full trying to
understand the multiple interacting systems that resist simplistic models.
- The central theme of both special issues is complexity
apparently nothing new for biological systems.
- We can now emphasize the complexity of circadian systems as we have
recently gained enough knowledge to free ourselves from the inheritance
of a past of looking for simple loops and cycles.
- As with any other sensory function, circadian systems need to
discriminate between signal and noise. One way of doing so is to
probe actively for signals, modulating the strength of a given
physical or chemical stimulus according to circadian time rather than
passively responding to them. This creates zeitnehmer
(time taker)
loops that are both input and output of the clock (an unimaginable
complexity for the simple sequential model) which have the interesting
consequence of increasing the robustness of the system.
- Another aspect of complexity is the presence of several oscillators
in the same organism. Circadian clocks are not confined to the
central nervous system but are also present in peripheral organs:
examples have been found in invertebrates, like fruit flies and moths,
and in vertebrates, like zebra fish and mouse. Peripheral
oscillators are self-sustained, as evinced by in vitro studies, but
show a great deal of variation in their robustness and responsiveness
to external (i.e. light) and/or internal (i.e. hormonal and neuronal)
stimuli.
- The physiological implications of relying upon a multi-oscillator
system are particularly evident in birds. The avian time-keeping
system is the product of the dynamic interplay between anatomically
distinct pace-maker components. The flexibility in the interaction
is particularly important in helping the circadian system cope with
extreme environmental conditions such as those experienced by
high-Arctic (low-amplitude light variations in midsummer) or migratory
(travel between time zones) birds.
Kippert attributes the origin of complexity in these circadian systems to the
environment: the conferees were not surprised
to also find complexity in biological timing mechanisms, considering
that they have evolved in response to a complex environment (which we
fail to reproduce in our simple artificial laboratory conditions) ....
Their contribution brings into focus once again the notion, held all
along by the honouree of the conference, that complex environments will
necessarily breed complex timing mechanisms.
He thus falls into his own reductionist
trap. The environment no more produces complex systems than horse hair
and cat gut produce string concertos.
How could rocks, air and sunlight produce complex biological clocks?
How could they invent timing mechanisms that allow birds to migrate by the stars
and the earths magnetic field, and to compensate for solar angle
and changing seasonal light, and find their breeding grounds unerringly
after thousands of miles of flight?
The complex parts of the biological clocks
reside in multiple organs and genes, which communicate with each other
through feedback loops and compensation techniques. The systems
baffle the researchers who try to study them, yet we are told to believe
that time, chance and aimless processes of natural selection produced
these wonders. Which is more amazing: the clocks, or the evolutionists
who attribute them to a blind watchmaker?

NASA Center Tolerates the G Word 11/15/2001
Exclusive The
Jet Propulsion Laboratory,
a focal point of NASAs Origins
program and search for life,
permitted the G word (God), and even applauded it, during an outdoor
patriotic celebration Thursday. An ad hoc choir made up of
employees, accompanied by JPLs amateur jazz band, The Big Band
Theory, sang and played a mixture of American songs: America,
America, God shed His grace on Thee / And crown thy good with
brotherhood from sea to shining sea .... Mine eyes have seen the
glory of the coming of the Lord / He is trampling out the vintage
where the grapes of wrath are stored / He hath loosed the fateful
lightning of His terrible swift sword / His truth is marching on.
A special third verse was substituted in the finale, Battle Hymn
of the Republic, in honor of the victims of September 11:
Now the fateful lightning strikes again across our peaceful land:
New Yorks best and finest lie at rest in Gods almighty hand.
As we strive for truth and justice, and for freedom make our stand,
For peace were marching on.
Glory, glory, hallelujah! Glory, glory, hallelujah!
Glory, glory, hallelujah! His truth is marching on.
The program was well received by a moderately large audience in the central
plaza, with a huge American flag draped from the 10-story administration
building behind the choir.
It was very nice of JPL to stage this
performance put together by employees, when a few months ago any event
using the G word (except in ridicule) would have
been uncomfortable at best. (JPLs newsletter
routinely advertises gay-lesbian support groups and talks by atheists,
but squelches announcements by Bible-study groups on campus.)
Now that patriots and Christians have had the stage
for a few minutes, we would like to see if the
Darwinists can come up with something better that will stir the
hearts of the those who borrow God-words when
terror strikes, but otherwise have no use for them:
O ugliful for stinking slime that sees beyond the years /
Thy bubbling hydrothermal vents give rise to blood and tears ....
Gory, gory evolution; Gory, gory evolution;
Gory, gory evolution; 'Tis ruthless stumbling on.

Honey, You Smell Good; Lets Evolve 11/15/2001 According to
Nature Science
Update, evolutionists have a new twist on sexual selection.
By studying sticklebacks (a small fish), researchers at Max Planck
Institute in Germany think that the females can smell which males
have a better immune system. They mate with the ones with the
best MHC gene complex (involved in immunity) to get
a better chance of having offspring that will survive. The
reporter hints that this effect may also work in humans: In 1995,
the famous sweaty T-shirt study showed that women prefer
the smell of sweat from men whose MHC genes are dissimilar to their own,
hinting that the odour warns women not to mate with close relatives.
Dont tell this to the deodorant
companies. If you mask your B.O. you may be hindering evolution.
How are little fish-brains supposed to understand genetics, or care whether
their kids have kids? As usual, the disclaimers are at the very
end of the article, after the confident headlines have done their
bluffing: How humans, mice and sticklebacks detect MHC profiles
using body odours is a mystery. We dont know whether
the odour differences are directly from MHC or from different bacteria
living on the animals skin....

Blind Mole Rats Keep Biological Clock Running 11/14/2001
A paper by Israeli scientists in the
Proceedings
of the National Academy of Sciences
finds that mole rats in Israel that have lost their sight due to
living underground in the dark are apparently still able to maintain
circadian rhythms. Expression of genes thought responsible
for circadian rhythms are enhanced, and the harderian gland is
substantially larger: The expression of Clock and MOP3
[possible circadian rhythm
genes] in the harderian gland of Spalax is remarkable and should
be emphasized: the harderian gland of Spalax is tremendously
hypertrophied, occupying the entire eye-socket, whereas the eye is
degenerated (0.7 mm in diameter), subcutaneous, and embedded in that
huge harderian gland. It was previously suggested that
the harderian gland of Spalax is a possible photoreceptor and
photoperiodic organ. They conclude that
The mosaic evolution of the Spalax eye, harderian gland,
and brain, and its circadian genes provides a dramatic model of
tinkering evolution at both the molecular and organismal levels.
From an evolutionary perspective, the genetic basis of circadian
rhythms in blind subterranean mole rats may be different from that of
strictly diurnal or nocturnal and sighted mammals.
This paper is listed under the category
Evolution but really proves nothing. The mole rats are still
mole rats, they have the same organs (whether enlarged or atrophied), and
have no new capabilities. Both creationists and evolutionists
accept that gene expression and phenotype can be influenced by environmental
factors. The paper, furthermore, is filled with wiggle words like
might, may, possibly, and could, and evolutionary puzzles:
the genetic phylogenies are mixed up (some of the mole ratss
genes are closer to humans than to other rodents); the authors characterize
the development as mosaic evolution (what on earth is that?)
and convergence (definition: multiplied miracles), and it
is not clear whether these genes or the harderian gland are associated
with circadian rhythms in the first place.
The authors claim this is a dramatic model of
tinkering evolution at both the molecular and organismal levels,
yet leave you wondering, so wheres the evolution, and
who, pray tell, is doing the tinkering?

Darwin for Children 11/14/2001
Evolution-based books for children are nothing new; The Water
Babies, The Land Before Time and even
Berenstein
Bears help predigest Darwinian concepts for young minds.
Now, in his new book
Animal
Baby-Sitters, Cornell biologist Paul Sherman
explains for children a mystery that has puzzled
evolutionary biologists for years why some animals postpone
breeding in order to stay home and help their families may
actually make good evolutionary sense. His research has
studied how the offspring of scrub jays, crows and naked mole rats help
the population reproduce by ensuring the survival of the next
generation. So its not really altruism, but an indirect
application of good old Darwinian survival of the fittest.
According to the report in UniSci International
Science News, The authors are betting that some of
their young readers will be intrigued by animal stories about behaviors
that pose many questions and offer some but not all of
the answers. Its never too early, Sherman
says, to get children hooked on the magic and mysteries of
behavioral biology.
Notice the words magic and
mystery, and they told you evolution was scientific fact.
No, evolution is a set of magical tales, mystery stories and what-if
conjectures that can explain anything and everything, even opposite
things, so long as no God is involved. Get em hooked

Bodys Energy Motor Takes Breaks 11/13/2001
The Proceedings
of the National Academy of Sciences has another new paper about ATP
synthase, the ubiquitous motor protein of all life. Japanese scientists
have found that it pauses for several seconds between its rapid rotational
cycles, for causes not yet known. The pauses appear to be related to
the presence of ADP-Mg.
If youre not yet excited about ATP
synthase, here are a couple of good reasons to learn about it: (1) Its
running your body right now. Trillions of these exquisite little
motors are providing the energy for everything you do, and yes, the
biologists call them motors, even describing their parts as
rotors and stators. These incredibly tiny molecular machines are
almost 100% efficient. Scientists are astounded at these motors; one
of its discoverers, Nobel laureate Paul Boyer, calls ATP synthase a
splendid molecular machine. Scientists only began to understand it within the last seven
years. (2) ATP synthase is a prime example of why chemical evolution
is a dying theory. All life, even the simplest bacteria and blue-green
algae, have them. These motors are far too complex and perfect to
arise by chance. The DNA that codes for them is also far too complex
and perfect to arise by chance. Neither would emerge from the primordial
soup by itself, but both need each other. Are we staring at prima
facie evidence for God?
Theres a lot of material out on ATP synthase, both
lay articles and detailed scientific papers; use your favorite search
engine and learn about those little motors inside you. Here is a list of
scientific papers to get you started.

Cells Golgi Body Recycles Itself Continuously 11/12/2001
The Golgi apparatus, a maze of channels near the nucleus
of a cell whose function was mysterious a few decades ago, is
gradually revealing its secrets. Scientists at Virginia
Tech and Heidelberg have found that the proteins making up the
apparatus are constantly being renewed, according to
EurekAlert.
One of the scientists describes what the Golgi body does:
The Golgi apparatus is a complex organelle. It is involved in the
processing of proteins destined for either secretion or for the outer
surface of the cell. Traditionally, scientists have looked on the
Golgi apparatus as a fixed structure that processed proteins in an
assembly-line fashion.
The organelle is a cup-shaped arrangement of layers of
flattened sac-like membranes thats located in a characteristic
place near the cells nucleus. Proteins are processed
through the layers of the Golgi apparatus, with enzymes in each layer
causing modifications as the proteins proceed through the layers,
finally to be shuttled into vesicles that take them to the cells
surface.
Vesicles are bubble-like containers that bud from the Golgi apparatus and transport proteins to the cell's surface membrane. The vesicles themselves are made of proteins, which are absorbed by the surface membrane when they have completed their mission.
Proteins are delivered to the Golgi apparatus for
processing in vesicles that bud from the endoplasmic reticulum.
Therefore . . . there is a constant flow of materials from the
endoplasmic reticulum through the Golgi and to the cells outer
surface.
The new central finding about the Golgi body is that it is
not a fixed structure, but that every component of it is recycled
through the endoplasmic reticulum. This recycling allows the
replacement of frayed proteins, acting as a kind of quality control to
ensure the structure can perform its function.
Update 01/11/2001: More on the Golgi
apparatus in Science,
the central protein sorting station of the cell,
especially how it creates protein vesicles for transport: a very
complicated series of steps involving enzymes and lipids working together.
If you drew pictures of cells in biology
class years ago, just about all your teacher and textbook knew about
the Golgi body was its
name. Now we are seeing that it is a key processing site for
proteins built by the ribosomes, and part of a complex assembly line
with quality control built in. All these operations require energy
that is generated by the ATP synthase motors, and everything is
orchestrated by the master control library in the nucleus.
Articles like this usually hasten to discuss how we
might use this knowledge for medicine or pharmaceuticals, but almost
never ask the obvious question, How did these complex factories
arise?. They just assume they evolved
somehow. Surely more biochemists somewhere are beginning to have
serious doubts that all this complexity could be the result of blind,
purposeless, random collisions of molecules.

A Merry Heart Prevents Heart Disease 11/12/2001 Researchers at Johns Hopkins have found that a positive

if they had a good attitude. The power of positive thinking
was strong even when traditional risk factors like cholesterol, weight
and smoking were taken into account.

Relativism Wanes as Sept. 11 Events Illustrate Reality of Evil 11/09/2001
The terrorist attacks of September 11 are causing many to recognize
the reality of evil, says ABC News.
Prior to that date, it would have been politically incorrect or
judgmental to describe anyones world view as good or evil,
but now many are saying the E word is the only appropriate
description for the deeds of the terrorists and the world view
that produced them. ABC quotes
various experts on whether it is deeds or people that are evil,
whether everyone has the seeds of evil, and whether evil is
an intrinsically religious concept or not. The article gives
favorable press to spokesmen who believe there are absolute standards
of good and evil a concept often scoffed at by intellectuals
prior to September 11.
We may be seeing the downfall of
postmodernism. Remember how shortly after September 11,
even scientists were appalled and
were asking for prayer.
As time goes by, will the postmodernists and relativists come
out of hiding? Well have to see, but right now,
most audiences would boo and jeer someone who would dare allege the moral
equivalence of jihad and antiterrorism.
The Bible teaches the objective reality of evil. Evil began with
Satans
rebellion, infected all mankind at
Adams fall, and is only
conquerable through
redemption
in Christ. It also commands us to
hate
evil, and authorizes governments to
punish
evildoers. But in Darwinian philosophy, evil
is an undefined term. If anything, evil could only be that which

Alabama Keeps Warning Stickers in School Science Textbooks 11/09/2001
The Alabama Board of Education approved without dissent the placement of warning stickers
in its school science textbooks that say evolution is a controversial theory . . . .
Instructional material associated with controversy should be approached with an open mind,
studied carefully, and critically considered. The stickers are a milder form
of earlier warnings that encouraged students to ask specific questions about evolution,
such as why transitional forms were lacking in the fossil record. The new move is
somewhat of a compromise between groups like the National Center for Science Education
that wanted no warnings, and the Christian Coalition and the Eagle Forum who were concerned
the board might drop the warnings entirely. Source:
Los
Angeles Times.
Isnt it bizarre that evolutionists do not want
students to think? These people are from the same mold that screamed
academic freedom! to teach Marxism, anti-war sentiments and every liberal
agenda in the 60s. From their point of view, questioning Darwinism is as silly
as questioning gravity, but in actuality, its all about power. They want to
maintain their stranglehold on educational policy relating to origins, because it is
Darwinism that gives the appearance of scientific respectability to individual
autonomy and moral relativism. So they continually portray the ones wishing
for academic freedom to question Darwinism as religious radicals.
Whats
so harmful about telling students that evolution is controversial and should be
approached with an open mind,
studied carefully and critically considered? Why must the world be
kept safe for Darwinism? If anything illustrates the false facade of evolution
as science, this is it. Science is supposed to be about weighing evidence with
an objective mind. Lets put the evidence out there and give students
logical thinking skills so they can find out for themselves if evolution is credible.
If evolution has to be protected from scrutiny, it is not science. Help your

Too Much Design Proves Evolution
11/09/2001
Indeed, not the least of Darwins achievements was to lay the argument by design to rest,
declare two evolutionists in a paper published this week in the
Proceedings
of the National Academy of Sciences. But how are we to
explain the bewildering complexity in the living cell?
In a dexterous turnaround, two evolutionists parry
evidence for over-design into evidence for no
design. Gerald Edelman and Joseph Gally first distinguish between
redundancy and degeneracy. Engineers often use redundancy (backup
systems of the same structure), but otherwise trim their design to the
essentials, avoiding superfluous parts. Degenerate
systems, on the other hand (no moral connotations in this context),
contain multiple different structures that accomplish similar
functions: more than one way to skin a cat, so to speak.
Edelman and Gally next establish that life is replete with examples of
degeneracy: (1) There are multiple DNA codons for the same amino acid,
(2) Genomes have long repetitive strands of so-called junk DNA and
multiple genes for the same function,
(3) Organisms lacking essential proteins sometimes find
alternate ways to fulfill the missing ingredients function, (4)
Antibodies that are structurally different can have the same immune
effect, (5) Nervous systems are characterized by an overabundance of
pathways. They argue that degenerate systems like these are
both a prerequisite for and product of natural selection, not design.
Unguided, non-directed processes of evolution would be expected to have
a degenerate pool of possibilities to draw from. Selection
pressures would preserve whatever ingredients achieve better
fitness.
The authors concede this is just a tentative hypothesis,
but believe that the concept of degeneracy will prove fruitful in
understanding many aspects of evolution: In our limited
experience so far, we have found that systems selected for high
degeneracy with respect to any given set of outputs also show high
complexity. Although a general functional dependence of
degeneracy on complexity has not yet been formally derived, it is an
interesting conjecture [emphasis added] that the two properties
go hand in hand.
PNAS should have a separate category for
interesting conjecture papers to segregate them from real
scientific papers. These authors think they have hit on something
new, but there are several reasons their speculation wont
work. First, the number of
useful combinations of anything is just a tiny fraction of the sea of
possibilities. We reported September 6 that biochemists are looking
for a needle in thousands of haystacks when trying to identify useful
polypeptides among all the possible combinations of amino acids.
What advantage would a cell have in carrying around quintillions of
useless structures for the one or two that might do the trick?
Wouldnt natural selection select these away as dead weight?
Furthermore, many cellular structures are irreducibly complex and must
have been completely functional from the beginning, before natural
selection could be considered. Also, this provides no help for the
chirality problem, the origin of handedness
in biomolecules, again preceding natural selection.
The authors try to replace an engineering god with
a tinkering god, but they second-guess what a designer would do.
True, organisms maintain a plethora of alternatives, but
these are not random; they work together in a variety of effective
ways. A better explanation is that the Creator built a high level
of adaptability into the system to cope with changing environments.
Animals migrate into forests and deserts, and have to survive
winter and summer, wet and dry, high and low, and a host
of other challenges.
Evolutionists cannot just knock over a human engineering
model of design like a straw man and
think they have disproved a Designer.
The authors of this paper claim that Darwin disproved the argument from
design, but then stare incredible design in the face and claim it proves
Darwin right. Its ironic that
they use Poes Purloined Letter as a symbol of something
right under your nose that you cant see.

olfactory nerves to the brain and found a surprise. Wondering how just 1000 nerves could respond
to 10,000 odors, they discovered that the receptors combine their signals into a kind of
language to vastly multiply the possible messages to the brain. So instead of dedicating an
individual odor receptor to a specific odor, the olfactory system uses an alphabet of receptors
to create a specific smell response within the neurons of the brain.
The paper is published in the Nov 8 Nature.
The sense of smell has been one of the least understood of the senses,
and now it just got tremendously more complex. Sorry, evolutionists; it must be tough these days.

Fossil Cockroach Found in Exquisite Detail 11/07/2001
Paleontologists have found the largest fossil cockroach ever (3.5 inches long) in a coal mine in Ohio
(click this Ohio State press release
for details and pictures). The fossil shows fine details, even veins in the insects wings.
The fossil is alleged to be 300 million years old.
The fossil roach is similar to living roaches, only larger. It is alleged to be basically unchanged for
300 million years, during which time the dinosaurs arose, evolved for 180 million years, went extinct, and
mammals arose and diversified into their many forms. Ask yourself whether it is reasonable to (1) believe
roaches didnt evolve for 300 million years, or (2) question the credibility of evolutionary stories.

Why the Chinese Didnt Develop Geology 11/07/2001
The Geological Society of America thinks that
the reason the Chinese never developed a science of geology is apparent in their art. Chinese
landscapes lack perspective and shadow, and according to Gary Rosenberg of the University Indiana,
this reflects their Taoist worldview. The lack of interest in a geometric characterization of space
reflected their priority to experience the void beyond time and space, the source of primal energy,
in contrast to Western European artists who were obsessed with geometric perspective because it
manifested the existence of God in Nature . . . Western geometric space also visually facilitated an understanding
of the continuity of spatial relationships that was vital to geology and which the Chinese perspective of
resonance obscured.
The world view of a religion or philosophy is intimately tied to the development of all the
sciences (see our explanation in the introduction to The Worlds Greatest
Creation Scientists or this paper by Michael Bumbulis).
Its ironic that the GSA here acknowledges the Christian world view in the development of their own
sciencegeologyyet takes a dogmatic anti-creation pro-evolution position, avidly pushing the slanted PBS Evolution materials, fighting creationism, and even writing a letter to Congress
protesting a proposal to discourage teaching evolution with dogmatism.

Life Depends on Water Dance 11/07/2001
Water shows surprising behavior at molecular level, declares a headline from
EurekAlert.
Researchers at the University of Maine have found that water molecules are able to enter tiny carbon
nanotubes in single file, in short bursts. They were studying how water reacts in the open and
in pores when they discovered that water acts in unexpected ways. The causes, they suggest,
are fluctuations in density and a kind of naturally occurring molecular dance that happens between the
hydrogen bonded water molecules in bulk water and in pores. The behavior of water,
still mysterious in many ways, directly affects many biological functions, such as the passage of
nutrients in and out of tiny pores in membranes. The paper is published
in the November 8 issue of Nature.
If scientists are still trying to figure out water, one of the simplest molecules, available for study
right under their noses, how can they make dogmatic claims about what supposedly happened during the
Big Bang billions of years ago under conditions not reproducible in the laboratory?
Water is an amazing substance absolutely crucial to life in countless ways. How something
so simple as water, composed of just two elements and three molecules, can baffle scientists
for centuries should teach us a lesson about how little we really know.

Sweat for Your Protection 11/05/2001
Maybe you should return that antiperspirant; scientists have found a disinfectant in human sweat. According to Scientific
American, a protein named Dermcidin is remarkably effective against several bacterial and fungal pathogens. This protein
bears no resemblance to two other known antiseptic proteins secreted in other parts of the skin. It is secreted in the sweat glands and then dispersed onto the skin surface.
Another front-line defense against disease is thus revealed. You are actually sweating all the
time, but only profusely when hot or active. Theres a reason for everything; scientists keep finding more and more
confirmations of Psalm 139:14 we are fearfully and wonderfully made.

Are Men Going Extinct? 11/01/2001
Thats what the British Medical Journal is asking, according to
EurekAlert.
With the advent of sperm banks, in vitro fertilisation, sex sorting techniques, human cloning, and same sex marriages, it is reasonable to wonder about the future role of men in society, say the authors. They are concerned that men may have nothing more to do
than engage in their favorite antisocial activities and destructive lifestyles. There is an urgent need to advertise and promote mens health in a positive way, stress the authors. They hope that initiatives such as the first World Congress on Mens Health and Mens World Health Day on 3 November 2001 will act as strong platforms to support long-term strategic and innovative research on mens health.
When men are treated in Darwinian terms as mere sperm donors, what do you expect? Maybe women are evolving to be self-contained
hermaphrodites. Hug a man this Saturday and help him not feel so superfluous. Especially
after hes just rescued women and children from a burning skyscraper. (Dont despair,
guys; Peggy Noonan still loves you.)

Placental Mammals Age 20 Million Years 11/01/2001
When it comes to the origins of placental mammals, fossils and DNA rarely see eye to eye, begins
a ScienceNow report on Academic Press
Daily InScight. For placental mammals, paleontologists argue they began 65 million years ago, but
molecular biologists argue for 100 million years based on evidence from assumed DNA
mutation rates. Now, paleontologists from San Diego State have now found chipmunk-size fossils in
Uzbekistan that appear to be placental mammals which they estimate are 85 million years old, bringing the
disagreeing data a little closer together.

Review: National Geographic November 2001
Geographica describes new 35,000 year old cave art discoveries in Italy that parallel those in Chauvet, France.
Those were assumed twice as old but are just as ornate as those from Lascaux. Also highlighted is
a new dinosaur graveyard in China. The feature evolutionary story, complete with ample artwork to
fill in the gaps, is the article on evolution of whales.
Readers are encouraged to read the alternate opinions on the Discovery Institute and Answers in Genesis websites to find out why what NG is claiming is not the truth, the whole truth, and nothing but the truth.
