Jarid2 may break the Polycomb silence
Historically, fly and human Polycomb proteins were considered textbook exemplars of transcriptional repressors, or proteins that silence the process by which DNA gives rise to new proteins. Now, work by a ...

When dying, bacteria share some characteristics with higher organisms
Do bacteria, like higher organisms, have a built-in program that tells them when to die? The process of apoptosis, or cell death, is an important part of normal animal development. In a new study published March 6 in the ...

Weightlessness weighs heavy on genes -- a fly's perspective
On Earth all biology is subjected to gravity. Some biological systems require gravity for correct orientation (geotropism: plants grow up, roots grow down). In the absence of gravity even human biology is affected: astronauts ...
