New York, NY (February 25, 2004) -- Within minutes of a stroke or other brain injury, neurons begin to die, a process that is followed by a cascade of further cell death, due in part to proteins released from injured cells. These proteins tell surrounding, healthy cells to die, a process termed apoptosis. These events occur over several days and may be more devastating than the original injury.Now, Weill Cornell Medical College researchers, working together with a team of researchers from Europe, have shed light on the proteins in healthy neurons that receive the apoptotic messages. In a study published in the journal Nature, they report the discovery that Sortilin, a protein whose function has been incompletely understood, plays a key role in conveying the message of apoptosis. Sortilin is a cell surface receptor, a protein that receives signals from outside the cell to modify the cell's behavior.
Almost 600 high school juniors and seniors will trade in a summer of work or sun-and-surf for the academic demands of Cornell's Summer College -- the nation's oldest such program, now in its 36th year -- which begins June 28. "The attraction here is to test the waters in an Ivy League institution, to get credit and to practice going to college before beginning freshman year," said Summer College Director Abby Eller.
An annual rite of spring on the Cornell campus is the screening of student films. This year, there's some Mike Figgis, Quentin Tarentino, Silence of the Lambs, a tip of the hat to Disney and plenty of action to make audiences…
Donations of leftovers by restaurants to food pantries and other human service agencies are declining markedly as restaurants become better managed, according to a study by Cornell's School of Hotel Administration.
"Many teenage pregnancies aren't accidental but intentional because of girls who see no life goals other than being a mother as realistically within their reach," says Andrea Parrot, Ph.D., a Cornell University women's health and human sexuality expert.
Wildlife preservationists have been successful enough in rescuing species from the brink of extinction that some of their methods should be applied to protecting children, says a Cornell University expert.
NEW YORK (March 22, 2005) -- The discovery by Weill Medical College of Cornell University researchers that a specific type of human fetal stem cell can co-differentiate simultaneously into both muscle and blood vessel cells may unlock the door to therapies that replace damaged tissue in the heart and other organs.Heart attack and other events can destroy cardiac muscle and the surrounding vasculature (blood vessels), so effective heart repair requires concurrent replacement of both these types of tissues.
On the heels of the drought of 1995 and the blizzard and deluge of 1996, the year 1997 is starting out normal for both precipitation and temperature, according to climatologists at the Northeast Regional Climate Center at Cornell.
