Awards, arrivals, and promotions
Congratulations to our latest award winners: Jean-Laurent Casanova has been recognized with the Stanley J. Korsmeyer Award for his work investigating the genetic basis of pediatric infectious diseases. The award is given by the American Society for Clinical Investigation, an honor society of phys...
Study identifies signals that make early stem cells
Stem cells work throughout our lives as a sort of handyman, repairing damaged tissues and renewing some normal ones, like the skin we shed. Scientists have come to understand much about how stem cells function when we are adults, but less is known about where these stem cells come from to begin w...
Awards, arrivals, and promotions
Congratulations to our latest award winners: Luciano Marraffini has been recognized with the Hans Sigrist Prize for his work developing a new approach to fight antibiotic resistance. The Hans Sigrist Prize recognizes work in a different academic field each year based on a decision by a faculty co...
Experiments explain the events behind molecular 鈥榖omb鈥� seen in cancer cells
Since scientists have begun sequencing the genome of cancer cells, they have noticed a curious pattern. In many different types of cancers, there are cells in which a part of a chromosome looks like it has been pulverized, then put back together incorrectly, leading to multiple mutations. For yea...
Researchers discover new aspect of gene regulation and a possible target for cancer drugs
There are about 20,000 genes in the human genome, but not all are used in all cells at all times. At any given moment, a cell is converting only roughly half its genes into proteins. And of those active genes, about 75 percent are regulated by a process known as 鈥淩NA polymerase pausing.鈥� This...
DNA strands often 鈥渨iggle鈥� as part of genetic repair
Sometimes, the molecules that make up life exhibit strange behavior. For instance, in simple organisms such as yeast, when genetic material becomes damaged, the affected DNA strands increase their motion, waving about inside the cell like a sail unfurled. Over the years, scientists have seen more...
In the News - Newsday - O'Donnell
听 Researchers at Brookhaven lab, Stony Brook and Rockefeller universities make new discoveries about double helix copying 听 "In Manhattan, Michael O'Donnell, who heads Rockefeller's Laboratory of DNA Replication, said the finding will change how students understand DNA replication. 'It's a pa...
Study reveals the architecture of the molecular machine that copies DNA
DNA replication is essential to all life, yet many basic mechanisms in that process remain unknown to scientists. The structure of the replisome鈥攁 block of proteins responsible for unwinding the DNA helix and then creating duplicate helices for cell division鈥攊s one such mystery. Now, for the ...
Researchers identify potential new leukemia drug target
New treatment options are badly needed for acute myeloid leukemia, a relatively rare form of cancer. The malignancy begins in the bone marrow, and from there can spread rapidly to the bloodstream, depriving the body of the essential blood cells that carry oxygen and fight infections. Now, new wor...
Helmsley Trust renews $15 million grant for novel digestive disorders research
by Wynne Parry, Science Writer The Leona M. and Harry B. Helmsley Charitable Trust has awarded a new three-year, $15-million grant to The 鸟大大影院 to help support the interdisciplinary Center for Basic and Translational Research on Disorders of the Digestive System. Established in 2...
