Fly brains filter out visual information caused by their own movements, like humans

Fly brains filter out visual information caused by their own movements, like humansTo cut down on the barrage of sensory information, the human brain ignores input caused by eye movements. Researchers have found a similar process in flies, whose brains mute signals generated by flight turns. This discovery gives researchers a new tool with which to study this silencing process. More »

Atomic view of cellular pump reveals how bacteria send out proteins

Atomic view of cellular pump reveals how bacteria send out proteinsWithin the structure of the simple but previously unexamined pump, researchers found a striking feature: a large, water-filled channel, a natural environment for the hydrophilic proteins that must pass through. Their work offers new insight into the mechanics that allow bacteria to manipulate their environments. More »

Cell division speeds up as part of antibody selection, study shows

Cell division speeds up as part of antibody selection, study showsIn response to an infection, the immune system refines its defensive proteins, called antibodies, to better target the invader. New research has revealed two mechanisms that favor the selection of B cells capable of producing antibodies finely tuned to target that invader. More »

Mutations in a single gene underlie vulnerability to two unrelated types of infections

Mutations in a single gene underlie vulnerability to two unrelated types of infectionsResearchers have identified a surprising case in which defects in a single immune gene render children susceptible to two very different diseases: aggravating, but treatable fungal infections, as well as invasive and potentially fatal bacterial disease. This finding suggests a dual role for that gene, RORC, in human immunity to infection. More »

Discovery points to a new path toward a universal flu vaccine

Discovery points to a new path toward a universal flu vaccineTaking advantage of a previously unknown mechanism within the immune system, researchers think they may be able to improve the immune response to the flu vaccine. If successful, this could mean less frequent flu shots that offer broad protection against the many strains of this ever-mutating virus. More »

Lifelong learning is made possible by recycling of histones, study says

Lifelong learning is made possible by recycling of histones, study saysResearchers have discovered a new mechanism that helps neurons make new connections with one another, the basis for learning. Their discovery focuses on one particular type of DNA-supporting protein, the histone H3.3, and its role regulating gene expression. More »

New faculty member probes actions of molecular machines in gene expression

New faculty member probes actions of molecular machines in gene expressionShixin Liu, a biophysicist and Rockefeller’s newest tenure-track faculty member, investigates how these individual machines within the cell interact, and, in many cases, cooperate to accomplish critical tasks, such as DNA transcription and gene regulation. Liu will establish the Laboratory of Nanoscale Biophysics and Biochemistry as of January 1. More »

Sequential immunizations could be the key to HIV vaccine

Sequential immunizations could be the key to HIV vaccineScientists have thought for some time that multiple immunizations, each tailored to specific stages of the immune response, could be used to generate a special class of HIV-fighting antibodies, so-called broadly neutralizing antibodies. These findings provide the first evidence supporting this approach. More »

Research reveals key interaction that opens the channel into the cell’s nucleus

Research reveals key interaction that opens the channel into the cell’s nucleusScientists have uncovered crucial steps in the dynamic dance that dilates and constricts the nuclear pore complex. Their ongoing work has shown this elaborate portal to and from the cell’s nucleus is much more than the inert structure it was once thought to be. More »

Research shows how antibodies produce vaccine-like effect against tumors

Research shows how antibodies produce vaccine-like effect against tumorsAntibody therapy not only kills cancerous cells, it can confer lasting protection by priming the immune system to remember a tumor. Scientists have found this process centers on antibody-binding receptors found on two types of immune cells. Their results suggest ways to improve anti-cancer treatments. More »
