In brief: Immune cells surveil intestine to prevent infections

Scientists found that immune cells called intraepithelial lymphocytes act as a surveillance force at the intestine, helping to generate an appropriate immune response to both friendly bacteria and dangerous pathogens.

In brief: New clues about how cells restart stalled replication

Scientists studying the cell’s DNA-copying machinery have discovered a molecular mechanism that helps reactivate it should it stop prematurely. Its function may prevent genetic errors like those that cause cancer.

Brain research points the way to new treatments for nicotine addiction

Scientists have discovered a group of brain cells that may play a role in keeping smokers addicted to nicotine. Their work could ultimately lead to new drugs to help people conquer their tobacco dependence.

Neuroscientist Vanessa Ruta promoted to associate professor

Ruta, who explores how brains produce such flexible responses to fixed stimuli, has been promoted to Gabrielle H. Reem and Herbert J. Kayden associate professor.

Daniel Kronauer, who uses ants to study social behavior, is promoted

Kronauer has been promoted to associate professor. He has dedicated his laboratory to investigating the molecular basis underlying complex social behavior among insects.

Mosquito sex protein could provide key to controlling disease

A protein transferred from male to female mosquitoes during sex influences female mating behavior—a phenomenon that could be exploited to limit the spread of mosquito-borne illnesses like Zika and dengue.

Michel C. Nussenzweig wins 2017 Sanofi-Institut Pasteur Award

Nussenzweig was honored at a ceremony today at the Institut Pasteur in Paris.The award recognizes investigators for past or ongoing work demonstrating real scientific progress in the life sciences.

Michael W. Young receives 2017 Nobel Prize in Physiology or Medicine

Young was honored for his discoveries of molecular mechanisms controlling the circadian rhythm. He accepted the Nobel medal and diploma from King Carl XVI Gustaf of Sweden.

Glial cells, not neurons, lead the way in brain assembly

Researchers have found that the cells directing the very first steps of brain formation are not other neurons, as scientists have long assumed. They've also uncovered previously hidden molecular pathways that attract neurons into the brain.

In brief: A close look at how HIV-fighting proteins slow the virus down

A new study sheds light on how the body fights back against HIV by mutating the viral DNA.

Rockefeller in the News

Scientific American

As [A. James] Hudspeth explored the neural mechanisms of hearing over the years, he developed a special appreciation for the intricate anatomy of the inner ear—an appreciation that transcends the laboratory. “I think we as scientists tend to underemphasize the aesthetic aspect of science,” he says.

Science

"'It is mind-blowing' that cells from such evolutionarily distant species can share these developmental instructions, says Ali Brivanlou, a stem cell biologist at The Rockefeller University in New York City and a senior author on the new study. The organizer 'has been conserved evolutionarily over hundreds of millions of years, so not seeing it would have been a surprise,' he says. But, 'There is something really emotional about looking that far back at human origin.'"

NIH Director's Blog

"[Michael] Rout and [Brian] Chait have spent more than 20 years trying to solve the structure of NPCs. Not only are NPCs large and constantly engaged in shuttling molecules in and out, they also represent moving machines."
