Supermassive black holes found at the centers of distant galaxies undergo huge growth spurts as a result of galactic collisions, according to a new study by astronomers at Yale University and the University of Hawaii. Their findings appear in the March 25 edition of Science Express. As massive, gas-rich galaxies in the distant universe collide, the central black hole feeds on gas that is funneled to the center of the merger. "As a result of the violent, messy collision, the black hole also...

The key to human individuality may lie not in our genes, but in the sequences that surround and control them, according to new research by scientists at the Stanford University School of Medicine, Yale University and the European Molecular Biology Laboratory  (EMBL). The interaction of those sequences with a class of key proteins, called transcription factors, can vary significantly between two people and are likely to affect our appearance, our development and even our predisposition to...

An international team led by Yale University has, for the first time, measured the mass of a type of supernova thought to belong to a unique subclass and confirmed that it surpasses what was believed to be an upper mass limit. Their findings, which appear online and will be published in an upcoming issue of the Astrophysical Journal, could affect the way cosmologists measure the expansion of the universe. Cosmologists use Type Ia supernovae"”the violent explosions of dead cores of stars...

Yale study may lead to better traps, repellents Yale University researchers have found more than two dozen scent receptors in malaria-transmitting mosquitoes that detect compounds in human sweat, a finding that may help scientists to develop new ways to combat a disease that kills 1 million people annually. These olfactory receptors in the mosquito Anopheles gambiae offer scientists potential new targets for repelling, confusing or attracting into traps the mosquitoes that spread a disease...
