'Nanodrop' test tubes created with a flip of a switch
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new device that creates nanodroplet "test tubes" for studying individual proteins under conditions that mimic the crowded confines of a living cell.   view more (2008-04-16)

More insight into Alzheimer's disease with Stanford discovery of possible cause
A peacekeeper in the body's defenses against infection may hold the key to understanding-and eventually treating-Alzheimer's disease. Researchers at the Stanford University School of Medicine discovered that when a molecule responsible for dialing down the immune system malfunctions in the brain... view more (2006-11-21)

Liquid ventilation
The main problem that premature babies have is that their lungs are not well formed. In order to alleviate this situation, the Nautical School at the University of the Basque Country has developed a liquid respiration respirator.   view more (2006-03-29)

Case and Cleveland Clinic researchers identify molecule in age-related macular degeneration
A dart-like molecule that adheres to proteins in the eye is the key that turns on the uncontrolled growth of blood vessels, according to researchers at Case Western Reserve University and the Cleveland Clinic Cole Eye Institute.   view more (2006-09-07)

Cellular molecule spurs growth of prostate cancer
University of North Carolina at Chapel Hill scientists have identified a molecule that stimulates the aggressive growth of prostate cancer.   view more (2005-11-29)

Solution to elusive problem
Scientists at the University of Leicester are on the way to solving a problem that has long beset chemists trying to study chemical reactions. To establish reaction mechanisms the observation of reaction intermediates is vital, but they are incredibly short-lived under normal conditions, and... view more (2003-01-21)

Researchers put the bite on mosquitoes
Few things sting like a mosquito's bite--especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well.   view more (2008-01-17)

How flesh-eating bacteria attack the body's immune system
"Flesh-eating" or "Strep" bacteria are able to survive and spread in the body by degrading a key immune defense molecule, according to researchers at the University of California, San Diego, School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences.   view more (2008-08-14)

Scientists Uncover Critical Step in DNA Mutation
Scientists at the Georgia Institute of Technology have made an important step toward solving a critical puzzle relating to a chemical reaction that leads to DNA mutation, which underlies many forms of cancer.   view more (2006-08-24)

Researchers find molecule that inhibits regrowth of spinal nerve cells
A molecule that helps the body's motor nerve cells grow along proper paths during embryonic development also plays a major role in inhibiting spinal-cord neurons from regenerating after injury, researchers at UT Southwestern Medical Center have found.   view more (2005-07-12)

Depression linked to previously unknown dopamine regulator
Researchers from Harvard Medical School have found a molecule that is unexpectedly involved in dopamine signaling, and in a manner that supports the potential of dopamine as an alternative target for treating depression.   view more (2005-07-29)

Study shows how the zebrafish gets his stripe
Scientists have discovered how the zebrafish (Danio rerio) develops one of its four stripes of pigment cells.   view more (2007-09-26)

Bacteria that cause tooth decay able to survive without important biochemical pathway
Leave it to the bacteria that cause tooth decay to be able to live without something all cells were thought to require.   view more (2005-12-14)

A new computational technique predicts side-effects of a major cancer drug
Researchers at the University of California San Diego have developed a novel computer technique to search for the side effects of major pharmaceuticals.   view more (2007-11-28)

Breast Tumors in Mice Eradicated Using Cancer Vaccine
A team from the University of Pennsylvania School of Medicine has shown that by using a cancer vaccine based on the bacterium Listeria monocytogenes, they can cure mice with established breast tumors.   view more (2005-09-15)

Research Team Is First to Model Photochemical Compass for Bird Navigation
A team of researchers at Arizona State University and the University of Oxford are the first to model a photochemical compass that may simulate how migrating birds use light and Earth's weak magnetic field to navigate.   view more (2008-05-01)

Australian researchers develop treatment to treat obesity
A team of researchers from the St Vincent's Campus in Sydney have developed a novel way to control the extreme weight loss, common in late stage cancer, which often speeds death.   view more (2007-11-06)

Historians help compile record of 50,000 lives
Scholars at the University of Essex have contributed 75 biographies to the new Oxford Dictionary of National Biography, a 60-volume publication charting more than 50,000 lives. Researchers from six departments and centres at the University were among more than 12,500 contributors to the British... view more (2005-02-01)

Small molecule offers big hope against cancer
DCA is an odourless, colourless, inexpensive, relatively non-toxic, small molecule. And researchers at the University of Alberta believe it may soon be used as an effective treatment for many forms of cancer.   view more (2007-01-17)

Scientists on track for early diagnosis of neurological diseases
Possible treatments for fatal neurodegenerative diseases such as CJD, Alzheimer's, Parkinson's could result from University of Edinburgh research to find out how specific proteins cause deterioration in brain function. The scientists have discovered for the first time that protein 14-3-3 plays a... view more (2003-07-01)

Animal study suggests inadequate sleep may exacerbate cellular aging in the elderly
Researchers at the University of Pennsylvania School of Medicine have shown that the unfolded protein response, which is a reaction to stress induced by sleep deprivation, is impaired in the brains of old mice.   view more (2008-06-30)

When proteins, antibodies and other biological molecules kiss, a new kind of biosensor can tell
When biological molecules kiss, a new kind of biosensor can tell. A new and deceptively simple technique has been developed by chemists at Vanderbilt University that can measure the interactions between free-floating, unlabeled biological molecules including proteins, sugars, antibodies, DNA and... view more (2007-09-21)

Biologists visualize protein interaction that may initiate viral infection
Biologists at Purdue University have taken a "snapshot" of a Velcro-like protein on a cell's surface just after it attached to the dengue virus, a linkup thought to initiate the early stages of infection.   view more (2006-02-10)

e-Science methods reveal new insights into antibiotic resistance
Large-scale computer simulations have pinpointed a tiny change in molecular structure that could account for drug resistance in Streptomices pneumoniae, the organism that causes childhood pneumonia and claims 3.5 million lives a year, mainly in developing countries.   view more (2005-08-16)
