Vast Gene-Expression Map Yields Neurological and Environmental Stress Insights

Berkeley Lab scientists lead broadest survey yet of RNA activity in any animal

A consortium led by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has conducted the largest survey yet of how information encoded in an animal genome is processed in different organs, stages of development, and environmental conditions. Their findings paint a new picture of how genes function in the nervous system and in response to environmental stress. (more…)

Prehistoric Predators with Supersized Teeth Had Beefier Arm Bones

*Combination of colossal canines and forceful forelimbs arose repeatedly over time*

The toothiest prehistoric predators also had beefier arm bones, according to results of a study published today in the journal Paleobiology.

Saber-toothed tigers may come to mind, but these extinct cats weren’t the only animals with fearsome fangs.

Take the false saber-toothed cats–also known as nimravids–and their catlike cousins, a family of carnivores called the barbourofelids. (more…)
