Evolution’s new wrinkle
A team of Princeton University scientists has discovered that chains of proteins found in most living organisms act like adaptive machines, possessing the ability to control their own evolution. The research, which appears to offer evidence of a hidden mechanism guiding the way biological organisms respond to the forces of natural selection, provides a new perspective on evolution, the scientists said.

The miseries of allergies just may help prevent some cancers, study finds
There may be a silver — and healthy — lining to the miserable cloud of allergy symptoms: Sneezing, coughing, tearing and itching just may help prevent cancer — particularly colon, skin, bladder, mouth, throat, uterus and cervix, lung and gastrointestinal tract cancer, according to a new Cornell study.

New laser method reproduces art masterworks to protein patterns
To illustrate the precision of their protein patterning technique, the research team reproduced a masterwork of Dutch painter Johannes Vermeer, specifically Girl with a Pearl Earring, in the miniature dimension of 200 microns wide or about the thickness of two hairs. The researchers also used their novel technology to replicate the brain’s complex cellular environment.

Without enzyme, biological reaction essential to life takes 2.3 billion years
All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these reactions proceed spontaneously, in the absence of enzymes — minutes, hours, days? And why even pose the question?

Fatty diet during pregnancy makes new cells in fetal brain that cause early onset obesity
A study in rats shows that exposure to a high-fat diet during pregnancy produces permanent changes in the offspring’s brain that lead to overeating and obesity early in life. This surprising finding provides a key step toward understanding mechanisms of fetal programming involving the production of new brain cells that may help explain the increased prevalence of childhood obesity during the last 30 years.
