Signals from the environment set off a cascade of changes that affect different genes in different ways. Therefore, traditionally, it has been difficult to study how such signals influence an organism. In a new study, researchers ...

(Phys.org)—In certain toy racecar tracks, sneaky players can flip a switch, trapping their opponents' vehicles in a loop of track. Cells employ a less subtle approach: they change the track's layout. In a study published ...

It was long thought that DNA, together with the genes encoded in it, determined genetic destiny. But equally important is coordinating when genes are turned on and off. In fact, the regulation of gene expression defines life ...
