In the News - The Scientist - Kronauer

Methylation’s Role in Eusocial Insect Behavior Questioned   "'Discovering that there is no evidence to support methylation as a reason why two ants can behave so differently was, on the one hand, a little sobering,' said study coauthor Daniel Kronauer of Rockefeller University in a press rele...

New findings challenge popular explanation for why a social insect becomes a worker or queen

The exquisite social hierarchy of insect colonies has long fascinated scientists. Take two eggs—both contain identical genetic material, but while one becomes a sterile worker, the other may develop into a queen that can reproduce. Workers perform brood care and other crucial tasks that keep the ...

Researchers develop gene-filtering tool to identify disease-causing mutations

Despite their bad reputations, the vast majority of mutations are not harmful. Even in very rare genetic disorders, only one or two genetic variations ­— out of tens of thousands — is actually the cause of disease. Distinguishing between harmful and harmless mutations has long been a challenge....

New research explores how the fly brain reroutes odor information to produce flexible behavior

Some responses come automatically, like reflexes. Others vary with circumstance and experience. A once-delicious smell can be easily overlooked during a stressful moment or when it calls to mind a bout of food poisoning, for instance. This happens because, within the brain, molecules known as neu...

In the News - Newsday - O'Donnell

  Researchers at Brookhaven lab, Stony Brook and Rockefeller universities make new discoveries about double helix copying   "In Manhattan, Michael O'Donnell, who heads Rockefeller's Laboratory of DNA Replication, said the finding will change how students understand DNA replication. 'It's a pa...

Study reveals the architecture of the molecular machine that copies DNA

DNA replication is essential to all life, yet many basic mechanisms in that process remain unknown to scientists. The structure of the replisome—a block of proteins responsible for unwinding the DNA helix and then creating duplicate helices for cell division—is one such mystery. Now, for the ...

Jean-Laurent Casanova elected to the National Academy of Medicine

Jean-Laurent Casanova, who investigates genetic vulnerability to infectious diseases among children, has been elected to the U.S. National Academy of Medicine, the health and medicine arm of the National Academy of Sciences. Casanova is professor and head of the St. Giles Laboratory of Human Gen...
