Our Solar System Is a Rare Gem
August 1, 2004
As if in time for the upcoming film release of The Privileged Planet (see 06/24/2004 headline), Philip Ball wrote a line for Nature Science Update that would have dismayed Carl Sagan and a host of SETI researchers: “Earth-like planets may be more rare than thought… In cosmic terms, our solar system could be special after […]

Gymnastic Enzyme Acts Like Logic Gate
July 31, 2004
An enzyme named vinculin undergoes “drastic” conformational changes, reports William A. Weis in the July 29 issue of Nature.1  Vinculin, with over a thousand amino acid links, is important at membrane junctions for transporting materials in and out of the cell.  It helps cellular “glue” exit the membrane so that neighboring cells can adhere to […]

Your Brain Learned Physics and Calculus Before You Did
July 29, 2004
Tilt your head to the right while moving to the left.  The neurons in your brain just solved Newton’s equations of motion, and performed complex vector calculus equations almost instantaneously.  That’s what four neurologists Washington University of Medicine (St. Louis, MO) essentially claimed in Nature July 29,1 describing how your brain interprets the information coming […]

Solar Systems Defy Theories
July 29, 2004
Stuart Ross Taylor (Australian National University, Canberra) feels left behind.  The astronomers have their nice, neat H-R diagrams to explain stars, but no such diagram exists for planetary scientists.  Our hodgepodge collection of planets, moons and small bodies defies classification, to say nothing of the extrasolar planets that have been discovered so far, mostly in […]

Spaghetti in a Basketball: How the Cell Packs DNA for Controlled Access
July 28, 2004
The beginning sentence of an article in Current Biology1 can’t help but grab your attention: Imagine trying to stuff about 10,000 miles of spaghetti inside a basketball.  Then, if that was not difficult enough, attempt to find a unique one inch segment of pasta from the middle of this mess, or try to duplicate, untangle […]

In the Last Days There Shall Be Scoffers
July 28, 2004
Current Biology this week contains two entries either attacking creationism or exalting Charles Darwin.1,2  Nigel Williams reports on the 100th birthday of Ernst Mayr (see 07/02/2004 headline), and his “tireless campaign against creationism”: Ernst Mayr, the renowned evolutionary biologist and champion of Darwin, celebrated his 100th birthday earlier this month by leading a scathing attack […]

Modern Cosmology Goes Schizophrenic
July 27, 2004
According to Charles Seife writing in Science,1 more cosmologists are taking parallel universes seriously.  This is a consequence of the Many Worlds interpretation of quantum mechanics, one possible mathematical solution to the effects of quantum “weirdness.”  If you think our headline is too harsh, read Seife’s opening in a Rod Serling voice while playing the […]

How Cells Build Hard Parts
July 26, 2004
You have rocks in your head, and it’s a good thing, or you would die of starvation and imbalance.  Living things have need of inorganic structures for various functions.  Can you name the mineral structures in your body?  The answer is: bone, dentin, enamel and otoliths.  The last three are specific to your head.  Dentin […]

Think Before You Speak
July 25, 2004
Children are capable of thoughts before they have the words to vocalize them, according to a study published in Nature July 221 (see also summary by Paul Bloom in the same issue2 and report on Science Now).  This contradicts the postmodernist view that thought is conditioned by language, and instead suggests that humans are innately […]

Evolutionists Consider Non-Darwinian Mechanisms
July 23, 2004
According to classical Darwinian evolutionary theory, variations in the germ lines produce phenotypic changes that, on rare occasions, prove beneficial to an individual, and cause an organism to outcompete its peers in the struggle for existence.  The hypothesis of Natural selection claims that the individual with a slightly beneficial variation, being more “fit,” leaves more […]

Old Rivers Cut Fast, Fast, Fast Through Solid Rock
July 22, 2004
A press release from University of Vermont says, “Geologists Discover Water Cuts Through Rock at Surprising Speed.”  A five-year study concluded that the Susquehanna and Potomac rivers cut through 10 to 20 meters of solid rock in 35,000 years, “a rate far more rapid than previously thought,”  especially since most of the cutting occurred during […]

Plant “Evolutionary Leftover” Now Deemed Vital
July 22, 2004
Photorespiration, “a biological process in plants, thought to be useless and even wasteful” and “just an evolutionary leftover” from an age when carbon dioxide was more prevalent, has been found to be “necessary for healthy plant growth and if impaired could inhibit plant growth,” according to a UC Davis study published in PNAS.1 (see also […]
