Key genes may contain insight into evolution of dinosaurs
(PhysOrg.com) -- Birds and alligators have little in common, other than that the first is sometimes the other's lunch. That hasn't always been the case, though, and that's what attracts Arkhat Abzhanov.

Our genes can be set on pause
New evidence in embryonic stem cells shows that mammalian genes may all have a layer of control that acts essentially like the pause button on your DVR. The researchers say the results show that the pausing phenomenon, previously ...

Humans, chimpanzees and monkeys share DNA but not gene regulatory mechanisms
Humans share over 90% of their DNA with their primate cousins. The expression or activity patterns of genes differ across species in ways that help explain each species' distinct biology and behavior.

'Runaway' development implicated in loss of function of the aging brain
The brain undergoes rapid growth and development in the early years of life and then degenerates as we progress into old age, yet little is known about the biological processes that distinguish brain development and aging. ...

Biophysicists unravel secrets of genetic switch
When an invading bacterium or virus starts rummaging through the contents of a cell nucleus, using proteins like tiny hands to rearrange the host's DNA strands, it can alter the host's biological course. The invading proteins ...
