Penn Study Identifies How Ebola Virus Avoids the Immune System
Researchers at the University of Pennsylvania School of Medicine have likely found one reason why the Ebola virus is such a powerful, deadly, and effective virus. Using a cell culture model for Ebola virus infection, they have discovered that the virus disables a cellular protein called tetherin that normally can block the spread of virus from... view more...

Once-fatal metabolic disorders treatable, says Stanford/Packard researcher
People with a class of rare genetic disorders that often lead to brain damage, coma and death can be successfully treated with drugs, says a researcher at the Stanford University School of Medicine and Lucile Packard Children's Hospital. view more (2007-05-31)
Climate Change Affecting Earth's Outermost Atmosphere
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 view more (2006-12-12)
Internal Clock, External Light Regulate Plant Growth
Most plants and animals show changes in activity over a 24-hour cycle. Now, for the first time, researchers have shown how a plant combines signals from its internal clock with those from the environment to show a daily rhythm of growth. view more (2007-07-10)
LSUHSC research finds evidence of RNA in structures essential to cell division
Research led by Mark Alliegro, PhD, Professor of Cell Biology and Anatomy at Louisiana State University Health Sciences Center at New Orleans, provides evidence for the first time that centrosomes, which play a key role in cell division, may carry their own genetic machinery, answering a controversial question of long standing. view more (2006-06-14)
Genetic breakdown in Fanconi anemia may have link to HPV-associated cancer
A genetic malfunction that causes DNA instability in people with the blood disorder Fanconi anemia may put them at high risk for squamous cell carcinomas linked to human papillomavirus (HPV), according to a study posted online ahead of print by Oncogene. view more (2008-12-04)
HIV's effect on white blood cells questioned by new research
Scientists have refuted a longstanding theory of how HIV slowly depletes the body's capacity to fight infection, in new research published today. view more (2007-05-22)
New target for anti-flu drug development
cientists at Cure Lab, Inc., a biotechnology company based in Canton, Massachusetts, in collaboration with researchers at Boston University and Harvard Medical School have discovered a potential new target for the development of anti-influenza (flu) drugs, including those that may be effective against potentially pandemic influenza strains like... view more...

How to enhance non-thermal effects of ultrasound
In recent years HIFU has been widely used for the treatment of solid tumors, such as liver tumor, bone tumor, and breast cancer. The mechanism for therapeutic actions of HIFU includes thermal effects and non-thermal effects with the latter dominated by cavitational effects. view more (2008-12-29)
Dartmouth researchers find new protein function
A group of Dartmouth researchers has found a new function for one of the proteins involved with chromosome segregation during cell division. view more (2009-01-09)
Researchers examine mechanisms that help cancer cells proliferate
A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies, researchers at UT Southwestern Medical Center report in the Aug. 7 issue of the journal Cell. view more (2009-09-02)
Scientists make malaria parasite work to reveal its own vulnerabilities
Researchers seeking ways to defeat malaria have found a way to get help from the parasite that causes the disease. view more (2009-01-29)
Stem cells' electric abilities might help their safe clinical use
Researchers from Johns Hopkins have discovered the presence of functional ion channels in human embryonic stem cells (ESCs). view more (2005-10-21)
Life cycle assessment essential to nanotech commercial development
Life cycle assessment (LCA) —a cradle-to-grave look at the health and environmental impact of a material, chemical, or product—is an essential tool for ensuring the safe, responsible, and sustainable commercialization of nanotechnology, U.S. and European experts conclude in a new report issued today. view more (2007-03-21)
Extra support helps obese women cycle to and from work
Increased daily exercise can prevent diabetes and cardiovascular disease in obese women, but getting started and maintaining new habits is a challenge. A new study by researchers at Karolinska Institutet shows that extra support and encouragement can help more women to exercise to and from work. view more (2009-05-06)
Stanford's nanowire battery holds 10 times the charge of existing ones
Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices. view more (2007-12-19)
