Nature Can’t Wait for Darwin Day

Darwin Day (Feb. 12, 2009) is months away, but Nature devoted a special issue to it this week.  The cover story, Darwin 200, includes 15 articles and features, some of which are available to the public.  Features include a list of celebrations and exhibitions around the world, including a re-enactment of Darwin’s voyage on a […]

Proteins Can Tie Knots

Your job today is to invent a chain that can tie itself in a knot.  The chain can contain little magnets and electrical parts, but when you let go of the ends, a knot will spontaneously form.  This means that one end must form a loop and the other end must thread the loop.  Give […]

Desperately Fleeing God in Cosmology

Does the fine-tuning of the universe require belief in God?  Or will multiverse theory allow for a self-perpetuating, eternal, godless cosmos?  Tim Folger explored this topic in an interview with Andrei Linde, a cosmologist currently at Stanford, in Discovery Magazine.  The opening line sums up the controversy: “Our universe is perfectly tailored for life.  That […]

Cell Chaperone Is an Optimized Two-Stroke Machine

Proteins need a protected space to fold, and the cell provides it: the GroEL-GroES chaperone (see 05/05/2003, 06/07/2006, and 02/13/2007).  More details keep coming in about this “protein dressing room” as scientists continue to probe its secrets.  Two new papers in PNAS by a team at University of Maryland and College Park reveal that this […]

Scientists Marvel at Enzyme Efficiency

Many chemical reactions occur from simple collisions.  One atom may have spare electrons, another may need them.  Attracted by each other’s valences, the atoms collide and bonds form.  Not so with biological enzymes: these molecular machines owe their efficiency to their three-dimensional shapes.  Made up of hundreds of amino acids, enzymes have “active sites” where […]

Evolution in Person

For a blind watchmaker, Evolution is quite the seer.  Science articles often personify Evolution into a wizard and worker of miracles.  This is odd, considering that evolution is supposed to be an aimless, purposeless process of chance and necessity with no goals in mind. Evolution, the Learner:  Evolution learns from past environments, we are told […]

Body’s Junk Is Useful Stuff

What’s the difference between junk and stuff?  The jokester replies that stuff is the junk you throw away, and junk is the stuff you keep.  When it comes to stuff in your body that scientists have called junk, you had better keep all of it, because your life may depend on it. Junk DNA:  The […]

Minding the Brain, or Braining the Mind?

There’s a battle brewing over who controls your brain: nature or your mind.  Materialist scientists are recognizing that creationists are getting a foothold on this hill and “declaring war over the brain,” according to an article in New Scientist.  Psychiatrist Jeffrey Schwartz fired this salvo: “Materialism needs to start fading away and non-materialist causation needs […]

How Not to Teach Evolution

Current Biology usually interviews a scientist for each issue.  In the October 14 issue,1 the subject was Dyche Mullins, a molecular biologist at UC San Francisco.  His story of how evolution was taught in high school should make teachers and parents take notice.     After the usual anecdotal fluff about what kind of cookies […]

How Cells Thread a Needle

Your challenge today is to invent a machine that can push a wet noodle through a straw.  It can’t pull it.  First it has to grab the end, then push it through without breaking it.  Oh, and there’s a catch; the straw has a plug at the far end and a constriction inside.  Give up?  […]

SETI Could Find Design in Neutrinos

Most of the scientists involved in SETI research are very antagonistic to Intelligent Design.  Nevertheless, they find the design inference perfectly “natural” when looking for ways to comb through natural phenomena for intelligently-designed signals.     Two new methods for detecting alien messages were reported by Science News in the Oct. 11 issue.1  Both involve […]

Living Better Bioelectrically

Electric eels are inspiring a new generation of fuel cells.  Science Daily reported that a remarkable fusion of engineering and biology may lead to tiny electronic devices that run on biology’s own energy currency, ATP.  “Engineers long have known that great ideas can be lifted from Mother Nature, but a new paper by researchers at […]

Darwinists Root for Obama

Ministers in churches are not allowed to promote political candidates, even though they do not take government money.1  Scientists, who often do take federal money in the form of grants, openly take positions on the presidential candidates they feel will further their interests.  Is this proper?     Both Nature and Science this week did […]

Designed for Health

Recent science reports on physiology and health contain suggestions of intelligent design as well as challenges to evolutionary theory. “Amazingly elegant, amazingly precise and very complicated” kidneys:  Scientists studying the effects of hypertension on kidneys have found that ATP acts not only as an energy source but an extracellular messenger.  It’s involved in helping arterioles […]

Turing Test Stands: Your Brain Outperforms Computers

What is the speed of thought?  Computer speeds are measured in megahertz and gigahertz, but that’s only part of the story.  The ability to compute an answer to a problem depends on the programming, too.  How does the brain compare with our best computers?  A scientist from UC San Francisco and one from the Salk […]
