DNA analysis for ancient manuscripts
Thousands of manuscripts produced in medieval times still exist today, but scholars have long bickered over when and where most of these works came into being. Now North Carolina State University professor Timothy Stinson is revealing their origins with DNA. Read on >>
Wild black wolves are descendants of wolf x dog crosses
The coloration of wild black wolves is the direct result of wolves interbreeding with domestic dogs says new research. Read on >>
Pride for the clan: Complete cave bear mtDNA genome sequenced
The complete Ursus spelaeus (cave bear) mitochondrial genome has been sequenced.

Swarming of desert locusts triggered by serotonin
Researchers have linked the radical transformation of desert locusts -- from harmless, solitary creatures to gregarious, swarm-forming insects -- to the common brain chemical serotonin. This discovery illuminates a mechanism within these desert locusts that initiates their switch from aversion to attraction, and may open the door to new methods of pest control. Read on >>

Mexican beaded lizard shares venom source with shrew
A new study says similar molecular changes have converted the same harmless digestive enzyme into a toxin in two very different types of animals -- a lizard and a shrew -- giving both a venomous bite.

Measuring gene expression in real time
In a new study researchers have invented a system for monitoring fruit fly gene expression even while the flies are zipping around inside their cages. Read on >>
 Snails and humans use same genes to tell right from left
Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body. Read on >>
Enzyme knockout lets mice pig out, stay lean
Researchers at the University of California, Berkeley, have identified a new obesity enzyme that plays an unexpectedly important role in controlling the breakdown of fat.

Researchers discover structure of viral nanomotor
The atomic structure of a nanomotor that packages DNA into the head segment of the T4 virus during its assembly has been determined by researchers at Purdue University and The Catholic University of America. The finding may eventually lead to a way to new way to attack viruses. Read on >>
