Funding from Kavli Foundation to establish new institute at Rockefeller devoted to neuroscience

The Kavli Foundation and The Rockefeller University today announced the formation of the Kavli Neural Systems Institute (Kavli NSI) at Rockefeller, funded by a $20 million endowment supported equally by Kavli and Rockefeller. The Institute will become part of a network of seven Kavli Institutes carrying out fundamental research in neuroscience, and a broader network of 20 Kavli Institutes dedicated to astrophysics, nanoscience, neuroscience, and theoretical physics.

Leslie Vosshall and Jean-Laurent Casanova elected to the National Academy of Sciences

Jean-Laurent Casanova and Leslie Vosshall elected to the National Academy of Sciences

Vosshall, who investigates how sensory stimuli are perceived and processed, and Casanova, who studies the genetics of infectious disease susceptibility in children, are among the new members and foreign associates to be inducted into the Academy in 2015. With Vosshall and Casanova’s election, Rockefeller now boasts 36 members or foreign associates of the National Academy of Sciences among its current faculty.

Researchers master gene editing technique in mosquito that transmits deadly diseases

Researchers master gene editing technique in mosquito that transmits deadly diseasesRockefeller University researchers have successfully harnessed a technique, CRISPR-Cas9 editing, to use in an important and understudied species: the mosquito, Aedes aegypti, which infects hundreds of millions of people annually with the deadly diseases chikungunya, yellow fever, and dengue fever.

Research suggests how mosquitoes evolved an attraction to human scent

Research suggests how mosquitoes evolved an attraction to human scentTo understand the evolutionary basis of the mosquito’s attraction to humans, scientists examined the genes that drive preferences of two different subspecies. Their findings suggest that Aedes aegypti aegypti acquired a love for human body odor, a key step in specializing on people. More »

Genetically driven gut feelings help female flies choose a mate

Genetically driven gut feelings help female flies choose a mateResearchers at Rockefeller University have determined that the Abdominal-B (Abd-B) gene, previously known as the gene that sculpts the posterior parts of the developing fly, is also important for a complex courtship behavior, at least in the case of female flies.

Sniff study suggests humans can distinguish more than 1 trillion scents

Rockefeller researchers tested the sensitivity of volunteers’ noses and brains, and determined that the human sense of smell is far more refined than previously thought. While individual volunteers’ performance varied, on average people can tell the difference between complex mixtures of odors even when they contain many of the same components. More »

Research shows combination of sensory signals draw mosquitoes in for a bite

Researchers used a genome editing technique to engineer a mutant version of the Aedes aegypti mosquito, which spreads yellow fever. The mutant was unable to detect carbon dioxide, and studies showed that this hindered its ability to detect a host, even in the presence of other sensory cues like heat and odor. The results can help inform the design of chemical repellents to block host-seeking behavior in both Aedes aegypti and Anopheles gambiae, which spreads malaria. More »

Mutant mosquitoes lose their appetite for humans

Scientists in Leslie Vosshall’s Laboratory of Neurogenetics and Behavior at Rockefeller used a genetically modified mosquito to show that a specific gene called orco gives the insects a strong preference for humans over other mammals, and that the insect repellant DEET uses this pathway to deter mosquitoes from biting.

Scientists detect an ancient odor-detecting mechanism in insects

A newly discovered family of receptors in the fly nose fills in a missing piece of the insect olfactory system, and also suggests a new role for a class of receptors long believed to be confined to the depths of the brain. More »

In lean times, flies can’t survive without their sense of smell

In the wild, survival means everything. Now, working with fruit flies reared under laboratory conditions, researchers at Rockefeller University have shown that in times of plenty, the sense of smell is irrelevant for survival. But when food is scarce, a well-functioning nose can mean the difference between life and death. More »

Insects evolved a radically different strategy to smell

To find their prey, insects use smell. But scientists at Rockefeller University have found that they don’t detect odors the same way other animals do. These findings, which break with the ideology of the field, could lead to new insect repellents that effectively and safely keep backyard biters at bay and reduce the incidence of diseases they transmit.
