The genetic switch known as NFkB-DNA-IkB. Rice University researchers discovered details of its molecular stripping mechanism through computer models of its energetic transformation. Rice University researchers have a new twist for those clinging to old ideas about a basic biological process.

The diversity of mammals on Earth exploded straight after the dinosaur extinction event, according to UCL researchers. New analysis of the fossil record shows that placental mammals, the group that today includes nearly 5000 species including humans, became more varied in anatomy during the Paleocene epoch - the 10 million years immediately following the event.

Researchers long have known that some portion of the risk of developing cancer is hereditary and that inherited genetic errors are very important in some tumors but much less so in others.

When the researchers reduced the activity of TET enzymes in developing granule cells, it impaired the cells' ability to form connections. From before birth through childhood, connections form between neurons in the brain, ultimately making us who we are. So far, scientists have gained a relatively good understanding of how neural circuits become established, but they know less about the genetic control at play during this crucial developmental process.

The largest study of survivors of the largest recorded outbreak of Ebola Virus Disease found they commonly reported complications such as vision, hearing and joint pain problems up to months after they were discharged from an Ebola treatment facility.
