Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

As you read this, cells in your eye are transmitting information to your brain, while cells in your heart and arteries work just as hard to keep that brain alive. Every one of these cells -- and others throughout the body -- depends on an internal process called endocytosis to keep the flow of cellular nutrients and information healthy and strong. . It's an incredibly important life process, and...

Cornell finds natural selection in humans

The most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species, according to researchers from Cornell University, Celera Genomics and Celera Diagnostics. . .. The comparisons within and between species suggest that about...

Cornell researchers find serious fish virus in Northeast for first time

A deadly fish virus has been found for the first time in a variety of freshwater fish in the northeastern United States by Cornell University researchers. . .. In May 2006, the researchers, in collaboration with the New York State Department of Environmental Conservation (DEC), isolated the virus in roun...

Cornell researcher helping develop quick, cheap HIV/AIDS test

A Cornell researcher is working to develop a quick, simple and cheap immune-system test for people in the developing world. It could help HIV/AIDS sufferers in the poorest countries get appropriate treatment to extend their lives, possibly by as much as 10 to 15 years. . The work is part of an $8.6 million international consortium, called the CD4 Initiative, led by Imperial College in London and...

Cornell lab confirms deadly fish virus spreading to new species

A lethal fish virus in the Great Lakes and neighboring waterways is approaching epidemic proportions, according to Paul Bowser, Cornell professor of aquatic animal medicine in the College of Veterinary Medicine. The viral hemorrhagic septicemia virus (VHSV), which causes anemia and hemorrhaging in fish, has now been identified in 19 species and poses a potential threat to New York’s $1.2 billion...
