Latest Rockefeller University Stories
Altering the DNA of a zebra finch could reveal the process of vocal learning in vertebrate brains, scientists at New York's Rockefeller University say. The zebra finch is one of several of its species that learn to speak by imitating other zebra finches, said Fernando Nottebohm, who heads the Laboratory of Animal Behavior at Rockefeller University. By manipulating the genes of zebra finches, Nottebohm and his team hope to learn more about the neural circuitry that allows songbirds to learn...
The ability to manipulate songbird genes may yield the molecular secrets of vocal learning and neuronal replacement.
Telomeres, the repetitive sequences of DNA at the ends of linear chromosomes, have an important function: They protect vulnerable chromosome ends from molecular attack.
In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane.
NEW YORK, June 17 /PRNewswire-USNewswire/ -- Fisher Center for Alzheimer's Research Foundation today announced it is moving forward with an online campaign to help fund new discoveries into Alzheimer's disease.
The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.
Similar architecture of an essential nuclear pore complex module and cellâ€™s vesicle coats supports common evolutionary origin.
The origins of many adult diseases can be traced to early negative experiences associated with social class and other markers of disadvantage.
Three immune system researchers were awarded the nation's richest prize in medicine and biomedical research on Friday for their work that led to new treatments for rheumatoid arthritis and diabetes.
Anyone who studied a little genetics in high school has heard of adenine, thymine, guanine and cytosine â€“ the A,T,G and C that make up the DNA code. But those are not the whole story.
