Expression of 'Blimp1' gene leads to the discovery of cells responsible for skin's sebaceous gland

Mice may not get zits, but they do have oily skin. This week, new research on mice from Rockefeller University shows how the cells responsible for oil production develop, and uncovers clues about how stem cells renew and differentiate. The research focuses on the skin’s sebaceous gland, which i...

Rockefeller researchers receive Gates Foundation grant for HIV vaccine research

The Bill & Melinda Gates Foundation has announced 16 grants totaling $287 million to create an international network of highly collaborative research consortia focused on accelerating the pace of HIV vaccine development. The grants will support a range of innovative approaches for designing an ef...

Scientists ID a single sugar that allows antibodies to fight inflammation

For years, researchers have struggled to understand how IVIG works. Its ability to treat autoimmune diseases seemed to be an apparent contradiction. Intravenous immunoglobulin (IVIG) is a complex mixture of IgG antibodies made from human plasma that contains the pooled antibodies from thousands o...

Evidence of rapid evolution is found at the tips of chromosomes

In terms of their telomeres, mice are more complicated than humans. That’s the finding from a recent Rockefeller University study, which shows that mice have two proteins working together to do the job of a single protein in human cells. The findings, published recently in Cell, suggest that the ...

Human stem cells can contribute to a developing mouse embryo, despite evolutionary differences

Using a newly derived line of human embryonic stem cells, Rockefeller University researchers have coaxed human cells to grow in mouse tissue. Ali Brivanlou, an embryologist who specializes in studying how the nervous system develops, and his colleagues demonstrated that despite the evolutionary d...

Sound investment: A new mathematical method provides a better way to analyze noise

Humans have 200 million light receptors in their eyes, 10 to 20 million receptors devoted to smell, but only 8,000 dedicated to sound. Yet despite this miniscule number, the auditory system is the fastest of the five senses. Researchers credit this discrepancy to a series of lightning-fast calcul...

Insights into the spliceosome suggest new explanations for generating biological complexity

While politicians debate whether evolution occurs, scientists are busy debating how it occurs. Now, new research from Rockefeller's Magda Konarska suggests that there are more ways than previously thought to achieve the impressive complexity characteristic of humans. Many organisms -- including h...

New research retraces connections between nose and brain

Every second our noses are bombarded with hundreds of smells, some pleasant, others not. Before we can react, however, our brains must first recognize an odor, and there are multiple steps between the nose and the brain. New research by Rockefeller’s Peter Mombaerts delves into the function and w...

Study of neurons leads scientists to re-envision vision

As we age, our eyes change shape — that’s why you see your eye doctor every year. But new research from Rockefeller University suggests that how the brain interprets visual information also changes with experience. And by studying the way in which nerve cells form connections between the eye and...

Netrin molecules help neruons shed their symmetry

For years, scientists have known that netrin molecules help guide growing neurons and their axons — the long tendrils that conduct electrical signals. But new research shows that these proteins are also important for helping create the neuron’s characteristically asymmetrical shape. In a recent ...
