Sea Urchin Genome Suprisingly Similar To Man And May Hold Key To Cures:
Sea urchins are small and spiny, they have no eyes and they eat kelp and algae. Still, the sea creature's genome is remarkably similar to humans' and may hold the key to preventing and curing several human diseases, according to a University of Central Florida researcher and several colleagues.
Evolution Of The Penis Worm: Research Reveals Embryos More Than Half A Billion Years Old :
Images of the developmental stages of embryos more than half a billion years old were reported by a University of Bristol researcher.
From A Lowly Yeast, Researchers Divine A Clue To Human Disease:
Working with a common form of brewer's yeast, University of Wisconsin-Madison researchers have uncovered novel functions of a key protein that allow it to act as a master regulatory switch -- a control that determines gene activity and that, when malfunctioning in humans, may contribute to serious neurological disorders.
Stretch A DNA Loop, Turn Off Proteins:
It may look like mistletoe wrapped around a flexible candy cane. But a new molecular model shows how some proteins form loops in DNA when they chemically attach, or bind, at separate sites to the double-helical molecule that carries life's genetic blueprint. Biologists have discovered that the physical manifestation of DNA loops are a consequence of many biochemical processes in the cell, such as the regulation of gene expression. In other words, these loops indicate the presence of enzymes or other proteins that are turned on. Now physicists at the University of California, San Diego have discovered that stretching the DNA molecule can also turn off the proteins known to cause loops in DNA.
Study Looks At Effects Of National Trauma On Americans' Health:
A study by psychologists at the University at Buffalo and the University of California, Irvine, has found that people's gender and ethnicity predicted their immediate response to the 9/11 terrorist attacks and their general state of health over the next two years.
