Selenium may slow march of AIDS
Increasing the production of naturally occurring proteins that contain selenium in human blood cells slows down multiplication of the AIDS virus, according to biochemists.   view more (2008-12-01)

Scientists developing food allergy treatment
A team of scientists from across Europe are embarking on new research to develop a treatment for food allergy.   view more (2008-12-01)

Scientists show gene mutation may cause immature lungs in newborns
Scientists have identified a gene critical to lung maturation in newborns and the production of surfactant, which lines lung tissues and prevents the lungs from collapsing.   view more (2008-11-25)

Scientists Present 'Moving' Theory Behind Bacterial Decision-Making
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases.   view more (2008-11-25)

Misreading of damaged DNA may spur tumor formation
The DNA in our cells is constantly under assault from oxygen, the sun's radiation and environmental stresses. Most of the time, our cells can repair the damage before it gets copied into a permanent mutation that could lead to cancer.   view more (2008-11-21)

Red, red wine: How it fights Alzheimer's
Scientists call it the "French paradox" - a society that, despite consuming food high in cholesterol and saturated fats, has long had low death rates from heart disease.   view more (2008-11-21)

Common cold virus came from birds
A virus that causes cold-like symptoms in humans originated in birds and may have crossed the species barrier around 200 years ago, according to an article published in the December issue of the Journal of General Virology. Scientists hope their findings will help us understand how potentially... view more (2008-11-20)

Luminescence shines new light on proteins
A chance discovery by a team of scientists using optical probes means that changes in cells in the human body could now be seen in a completely different light.   view more (2008-11-12)

Researchers aim to over-stress already taxed mantle cell lymphoma cells
Cancer cells are already stressed by the fast pace they require to grow and spread and scientists believe a little more stress just may kill them.   view more (2008-11-11)

Researchers describe how cells take out the trash to prevent disease
Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard. Similarly, individual cells that make up such biological organisms as humans also have sophisticated methods for managing waste.   view more (2008-11-11)

NC State finds new nanomaterial could be breakthrough for implantable medical devices
A team of researchers led by North Carolina State University has made a breakthrough that could lead to new dialysis devices and a host of other revolutionary medical implants.   view more (2008-11-11)

Quintet of proteins forms new, early-warning blood test before heart attack strikes
A team of Johns Hopkins biochemists has identified a mixed bag of five key proteins out of thousands secreted into blood draining from the heart's blood vessels that may together or in certain quantities form the basis of a far more accurate early warning test than currently in use of impending... view more (2008-11-10)

What makes an axon an axon?
Inside every axon is a dendrite waiting to get out. Hedstrom et al. converted mature axons into dendrites by banishing a protein crucial for neuron development.   view more (2008-11-10)

Protein 'tubules' free avian flu virus from immune recognition
A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response from infected cells, said Baylor College of Medicine... view more (2008-11-06)

Proteomics Study Yields Clues As To How Tuberculosis Might Be Thwarting The Immune System
A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.   view more (2008-11-06)

'Junk' DNA proves functional
In a paper published in Genome Research on Nov. 4, scientists at the Genome Institute of Singapore (GIS) report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species.   view more (2008-11-05)

New therapeutic target identified for rheumatoid arthritis
Researchers at Hospital for Special Surgery have identified a potential new therapeutic target that could be used to treat inflammatory disorders, such as rheumatoid arthritis.   view more (2008-11-05)

New research finds markers for esophageal cancer before it develops
Rhode Island Hospital researchers have identified genetic proteins, also known as biomarkers, capable of distinguishing changes at the microscopic level that can signal a precancerous condition in the esophagus.   view more (2008-11-04)

Lung airway cells activate vitamin D and increase immune response
Vitamin D is essential to good health but needs to be activated to function properly in the human body. Until recently, this activation was thought to happen primarily in the kidneys, but a new University of Iowa study finds that the activation step can also occur in lung airway cells.   view more (2008-11-04)

New method provides panoramic view of protein-RNA interactions in living cells
DNA, it has turned out, isn't all it was cracked up to be. In recent years we learned that the molecule of life, the discovery of the 20th century, did not -- could not -- by itself explain the huge differences in complexity between a human and a worm.   view more (2008-11-03)

Without glial cells, animals lose their senses
Sensory neurons have always put on a good show. But now, it turns out, they'll be sharing the credit. In groundbreaking research to appear in the October 31 issue of Science, Rockefeller University scientists show that while neurons play the lead role in detecting sensory information, a second type... view more (2008-10-31)

Researchers characterize potential protein targets for malaria vaccine
Researchers from Nijmegen and Leiden have now characterized a large number of parasite proteins that may prove useful in the development of a human malaria vaccine.   view more (2008-10-31)

A high-fat diet could promote the development of Alzheimer's
A team of Université Laval researchers has shown that the main neurological markers for Alzheimer's disease are exacerbated in the brains of mice fed a diet rich in animal fat and poor in omega-3s.   view more (2008-10-29)
