Specialized 'GPCR' proteins are the key to protecting the fly brain
In the brain, it's usually neurons that get all the attention. But there's another type of brain cell that's just as critical to our ability to think, walk and process information. It's the glial cell, and without it, neurons wouldn't last long. In a new report published in the October 7 issue of...
Alternative to cloning technique does not yield pure clones, Rockefeller scientists report
When is a clone not a clone? According to new research from Rockefeller University’s Peter Mombaerts, creating mice by a two-step transfer of DNA does not reliably produce animals that are genetic duplicates of an original, and in some cases even creates “cloned” mice of the wrong sex. Scient...
For sex to happen, the right receptors must align
Having sex is largely about being in the right place at the right time. That’s true not only in the singles scene, but also at the molecular level. Research by Rockefeller’s Donald Pfaff, published this week in the online edition ofProceedings of the National Academy of Sciences, shows that the ...
Scientists ID the genetic makeup of hair
Despite a $56 billion industry devoted to caring for and styling hair, we know surprisingly little about how it forms. A new paper in last week’s edition of Public Library of Science Biology from Elaine Fuchs’ laboratory at Rockefeller University begins to tease apart the genes, and the cells,...
Clearing jams in the copy machinery
Bacteria and humans use a number of tools to direct perhaps the most important function in cells -- the accurate copying of DNA during cell division. New research published this week in Molecular Cell from the laboratory of Rockefeller University's Michael O'Donnell, a Howard Hughes Medical Insti...
Humanity in transition
2005, Joel Cohen says, is the midpoint of a historic decade. Before this decade, young people always outnumbered older people; rural residents always outnumbered city dwellers; and the median number of women per child always exceeded two. By the end of this decade, none of this will ever be true ...
In flies, odorant receptors work together
Locating a bruised, three-day-old banana takes a keen sense of smell. Yet fruit flies have just 62 different odorant receptors – compared to a thousand or more that exist in humans. A new paper published this week by Rockefeller University researchers Leslie Vosshall and Elane Fishilevich shows h...
New gene in Fanconi anemia "explains" hallmark chromosomal instability
Surprising findings from just five patients has led to the first proof of how the rare disorder Fanconi anemia causes chromosomal instability. A team of international researchers, led by scientists at Rockefeller University, reports the findings in the September issue of Nature Genetics. The scie...
Rockefeller researchers show evidence of asymmetric cell division in mammalian skin
It took almost 10 years for Elaine Fuchs, Ph.D., a Howard Hughes Medical Institute investigator at Rockefeller University, to find a postdoctoral fellow who shared her curiosity for the direction of cell divisions in the skin. Then Terry Lechler, Ph.D., came along and the result is a new paper pu...
Never too much of a good thing
Changing levels of a single protein can produce many different outcomes An ongoing scientific argument surrounds the Wnt protein: Different research groups say that Wnt proteins are involved in cell differentiation, proliferation, fate determination, stem cell self-renewal and cancer. But which g...
