Anyone who has ever been subject to chronic stress knows that it can take a toll on emotions and the ability to think clearly. Now, new research uncovers a neural mechanism that directly links repeated stress with impaired memory.

UT Southwestern Medical Center cardiologists have uncovered how a specific protein's previously unsuspected role contributes to the deterioration of heart muscle in patients with diabetes. Investigators in the mouse study also have found a way to reverse the damage caused by this protein.

National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found ...

UCSF scientists have discovered the unexpected way in which a key cell of the immune system prepares for battle. The finding, they said, offers insight into the processes that take place within these cells and could lead to strategies for treating conditions from spinal cord injury to cancer. ...

(University of California - San Francisco) UCSF scientists have discovered the unexpected way in which a key cell of the immune system prepares for battle. The finding, they said, offers insight into the processes that take place within these cells and could lead to strategies for treating conditions from spinal ...

Patients with metastatic melanoma taking the recently approved drug vemurafenib (Zelboraf) responded well to the twice daily pill, but some of them developed a different, secondary skin cancer. Now, researchers at UCLA's Jonsson Comprehensive Cancer Center, working with investigators from the Institute of Cancer Research in London, Roche and Plexxikon, ...

(PhysOrg.com) -- The human genome contains some 3 billion base pairs that are tightly compacted into the nucleus of each cell. If a DNA strand were the thickness of a human hair, the entire human genome would be crammed into a space the size of a softball, but if it ...

An important part of saving a species is often understanding its DNA. Through a collaborative effort including 14 scientists representing organizations across Europe and the United States, researchers have been able to analyze the genome of the great ape species of the world. "A ...

Cold Spring Harbor, N.Y. The secret to pushing tomato plants to produce more fruit might not lie in an extra dose of Miracle-Gro. Instead, new research from Cold Spring Harbor Laboratory (CSHL) suggests that an increase in fruit yield might be achieved by manipulating a molecular timer or ...

Physicians use inhalation anesthetics in a way that is incredibly safe for patients, but very little is known about the intricacies of how these drugs actually work in children and adults. Now, researchers have uncovered what cells respond to anesthesia in an organism known as the C. elegans, according to ...

(Seattle Children's) Researchers have uncovered what cells respond to anesthesia in an organism known as the C. elegans, according to a new study from the Seattle Children's Research Institute.

Cancer researchers at Cold Spring Harbor Laboratory (CSHL) have carried out the first comprehensive study of the changes seen in the DNA of a patient with mast cell leukemia (MCL), an extremely aggressive subtype of acute myeloid leukemia (AML) with a very poor prognosis.
