Phys.org / Into the neutrino fog: The ghosts haunting our search for dark matter

Ciaran O'Hare scribbles symbols using colored markers across his whiteboard like he's trying to solve a crime—or perhaps planning one. He bounces around the edges of the board, slowly filling it with sharp angles and curling ...

Medical Xpress / Premature aging may result from immune responses triggered by faulty DNA repair

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that aid DNA in carrying out essential processes such as replication, repair, and transcription. Under ...

Medical Xpress / Family dinners may reduce substance-use risk for many adolescents

A new study by researchers at Tufts University School of Medicine finds that regular family dinners may help prevent substance use for a majority of U.S. adolescents, but suggests that the strategy is not effective for youth ...
