Even the smallest stroke can damage brain tissue and impair cognitive function
Blocking a single tiny blood vessel in the brain can harm neural tissue and even alter behavior, a new study in animals has shown.

Kidney failure under the microscope
Better targeted treatments for 20 percent of renal failure patients are on the horizon following a key discovery about the role of white blood cells in kidney inflammation.

Nature Climate Change: Action by 2020 key for limiting climate change
Limiting climate change to target levels will become much more difficult to achieve, and more expensive, if action is not taken soon, according to a new analysis from IIASA, ETH Zurich, and NCAR.

Scientists develop most advanced mind-controlled prosthetic hand yet
Researchers have developed a robotic prosthetic hand controlled by the thoughts of a woman with tetraplegia, which allows a degree of control and freedom of movement that has never before been achieved in this type of prosthesis.

New technique could make cell-based immune therapies for cancer safer and more effective
A team led by Michel Sadelain, M.D., Ph.D., Director of the Center for Cell Engineering at Memorial Sloan-Kettering Cancer Center, has shown for the first time the effectiveness of a new technique that could allow the development of more-specific, cell-based immune therapies for cancer.

Flaw in Alzheimer's drug trial test
New research led by Plymouth University Peninsula Schools of Medicine and Dentistry suggests that the cognitive test used in Alzheimer's drug trials is flawed.

Climate model is first to study climate effects of Arctic hurricanes
It seems like an oxymoron, but Arctic hurricanes happen, complete with a central

Ordinary heart cells become 'biological pacemakers' with injection of a single gene
Cedars-Sinai Heart Institute researchers have reprogrammed ordinary heart cells to become exact replicas of highly specialized pacemaker cells by injecting a single gene -- a major step forward in the decade-long search for a biological therapy to correct erratic and failing heartbeats.

Penn Study shows resistance to cocaine addiction may be passed down from father to son
Research from the Perelman School of Medicine at the University of Pennsylvania and Massachusetts General Hospital reveals that sons of male rats exposed to cocaine are resistant to the rewarding effects of the drug, suggesting that cocaine-induced changes in physiology are passed down from father to son.

Do-it-yourself viruses: How viruses self assemble
New research published in BioMed Central's open access journal BMC Biophysics, shows that the construction of intermediate structures prior to final capsid production (hierarchical assembly) can be more efficient than constructing the capsid protein by protein (direct assembly).

Exploding star missing from formation of solar system
A new study published by University of Chicago researchers challenges the notion that the force of an exploding star forced the formation of the solar system.

'Missing' polar weather systems could impact climate predictions
Intense but small-scale polar storms could make a big difference to climate predictions according to new research from the University of East Anglia and the University of Massachusetts.

Toward a new model of the cell
Turning vast amounts of genomic data into meaningful information about the cell is the great challenge of bioinformatics, with major implications for human biology and medicine.

IOF Young Investigator Awards in Kuala Lumpur recognize high-quality research abstracts
Five young investigators from the Asia-Pacific region have been awarded prestigious grants on the closing day the IOF Regionals -- 3rd Asia-Pacific Osteoporosis Meeting, a major medical conference organized by the International Osteoporosis Foundation in Kuala Lumpur.

Cartenoids found to reduce hip fracture risk in lean men
At the IOF Regionals 3rd Asia-Pacific Osteoporosis Meeting in Kuala Lumpur, researchers from the National University of Singapore and the Singapore Ministry of Health announced a study which links carotenoids to decreased hip fracture risk in elderly, lean Chinese men.

Worries about dementia how hospitalization affects the elderly
Older people often worry about dementia and while some risks are known, for example alcoholism or stroke, the effects of illness are less clear.

Chinese scientists discover evidence of giant panda's population history and local adaptation
A research team, led by Institute of Zoology of Chinese Academy of Sciences and BGI, has successfully reconstructed a continuous population history of the giant panda from its origin to the present. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
