Estrogen can reduce stroke damage by inactivating protein
Estrogen can halt stroke damage by inactivating a tumor-suppressing protein known to prevent many cancers, Medical College of Georgia researchers say. view more (2009-07-17)
New West Nile and Japanese encephalitis vaccines produced
University of Texas Medical Branch at Galveston researchers have developed new vaccines to protect against West Nile and Japanese encephalitis viruses. The investigators created the vaccines using an innovative technique that they believe could also enable the development of new vaccines against other diseases, such as yellow fever and dengue... view more...

UCSD researchers discover variants of natural tumor suppressor
Building on their 2005 discovery of an enzyme that is a natural tumor suppressor, researchers at the University of California, San Diego (UCSD) School of Medicine have now identified two variants of that enzyme which could provide new targets for therapies to treat diabetes, heart and neurological disease. view more (2007-04-10)
Research details how a virus hijacks cell signals to cause infection
A common virus that causes meningitis and heart inflammation takes a "back door" approach to evade natural barriers, then exploits biological signals to infect human cells. view more (2006-01-13)
Certain diseases, birth defects may be linked to failure of protein recycling system
A group of signaling proteins known as Wnt - which help build the human body's skin, bone, muscle and other tissues - depend on a complex delivery and recycling system to ensure their transport to tissue-building cell sites, according to a study at Cincinnati Children's Hospital Medical Center. view more (2007-12-21)
Potential breakthrough for T-Cell lymphoma patients with drug that mimics folic acid
Preliminary results of a pivotal Phase 2 clinical trial of pralatrexate (PDX), a drug that partially works by mimicking folic acid, showed a complete or partial response in 27 percent of patients with recurrent or resistant peripheral T-cell lymphoma (PTCL). view more (2008-12-10)
Global monsoon drives long-term carbon cycles in the ocean
Monsoon is a global system, and many arrays of evidence indicate that it drives long-term cyclicity of the carbon reservoir in the global ocean. view more (2009-05-08)
Image of myosin-actin interaction revealed in cover story of Molecular Cell
Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction. view more (2005-09-30)
Carbon dioxide emissions predicted to reduce density of Earth's outermost atmosphere by 2017
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research (NCAR) and Pennsylvania State University (PSU). view more (2006-12-12)
A virtuous cycle: Safety in numbers for riders
It seems paradoxical but the more people ride bicycles on our city streets, the less likely they are to be injured in traffic accidents. view more (2008-09-03)
Unheard of life history for a vertebrate
There is a newly discovered life history among the 28,300 species of known tetrapods, or four-legged animals with backbones. view more (2008-07-01)
Zeroing in on progeria: How mutant lamins cause premature aging
Children diagnosed with Hutchinson-Gilford Progeria Syndrome (HGPS) race through life against an unfairly fast clock. Cases are extremely rare-one in 8 million births-but time plays cruel tricks on HGPS newborns. view more (2005-12-14)
Does Facebook usage contribute to jealousy in relationships?
The more time college students spend on Facebook, the more likely they are to feel jealous toward their romantic partners, leading to more time on Facebook searching for additional information that will further fuel their jealousy, in an escalating cycle that may become addictive. view more (2009-08-07)
UGA researchers discover mechanism that explains how cancer enzyme winds up on ends of chromosomes
Human cancer cells divide and conquer. Unless physicians can control that division with surgery, chemotherapy or radiation, the wildly dividing cells will eventually destroy a person's life. view more (2008-07-11)
UK leads race to produce world's first clinical grade stem cells
The University of Sheffield has received a £2.6m grant to create some of the world's first embryonic stem cell lines that can be used for medicinal purposes. view more (2005-03-16)
Gene may hold key to future cancer hope
Scientists may have discovered a new way of killing tumours in what they hope could one day lead to alternative forms of cancer treatments. view more (2007-10-09)
Study finds reproductive health effects from low doses of bisphenol-A
New research from North Carolina State University and the National Institute of Environmental Health Sciences (NIEHS) shows significant reproductive health effects in rats that have been exposed to bisphenol-A (BPA) at levels equivalent to or below the dose that has been thought not to produce any adverse effects. view more (2009-06-17)
New ovarian stimulation technique offers more cancer patients the chance to preserve their fertility
Researchers have shown for the first time that it is possible to stimulate a woman's ovaries to produce eggs for collection during the final phase of the menstrual cycle. view more (2008-07-08)
Study finds hemlock trees dying rapidly, affecting forest carbon cycle
New research by U.S. Forest Service Southern Research Station (SRS) scientists and partners suggests the hemlock woolly adelgid is killing hemlock trees faster than expected in the southern Appalachians and rapidly altering the carbon cycle of these forests. view more (2009-02-27)
Researchers find how a common genetic mutation makes cancer radiation resistant
Many cancerous tumors possess a genetic mutation that disables a tumor suppressor called PTEN. Now researchers at Washington University School of Medicine in St. Louis have shown why inactivation of PTEN allows tumors to resist radiation therapy. view more (2009-06-10)
