Think globally, but act locally when studying plants, animals, global warming, researchers advise
Global warming is clearly affecting plants and animals, but we should not try to tease apart the specific contribution of greenhouse gas driven climate change to extinctions or declines of species at local scales, biologists from The University of Texas at Austin advise.

Fish know to avoid the spear
Fish are not as dumb as people sometimes think: marine scientists have found that fish that are regularly hunted with spearguns are much more wary and keep their distance from fishers.

Batteries charge quickly and retain capacity, thanks to new structure
Illinois professor Paul Braun's group developed a three-dimensional nanostructure for battery cathodes that allows for dramatically faster charging and discharging without sacrificing energy storage capacity.

New data published in Nature Genetics demonstrate that tiny LNA-based compounds developed by Santaris Pharma A/S inhibit entire disease-associated microRNA families
New data published in Nature Genetics demonstrates that tiny LNA-based compounds developed by Santaris Pharma A/S can inhibit entire disease-associated microRNA families.

Stanford researchers discover molecular determinant of cell identity
If a big bunch of your brain cells suddenly went rogue and decided to become fat cells, it could cloud your decision-making capacity a bit.

Life expectancy of severely mentally ill dramatically reduced due to poor physical health
Physical ill-health is rife among the severely mentally ill in Britain, according to new research published today by the University of East Anglia.

Former national leaders: Water a global security issue
Experts convening for a conference on the prospects of future water conflicts say the tradition of water as a source of international cooperation could be tested as tensions increase due to growing populations, urbanization, rising industrial, agricultural and household demands, climate change, and the depletion of

PMH researchers create an organic nanoparticle that uses sound and heat to find and treat tumors
A team of scientists from Princess Margaret Hospital have created an organic nanoparticle that is completely non-toxic, biodegradable and nimble in the way it uses light and heat to treat cancer and deliver drugs.

Preventive antibiotic use significantly lowers risk of infection with antibiotic-resistant bacteria in intensive care patients
Giving critically ill patients antibiotics as a preventive measure significantly reduces the risk of infection with highly resistant microorganisms, according to the largest prospective study of topical preventive antibiotics in intensive care unit patients, published online first in the Lancet Infectious Diseases.

Metabolite levels may be able to improve diabetes risk prediction
Measuring the levels of small molecules in the blood may be able to identify individuals at elevated risk of developing Type 2 diabetes as much as a decade before symptoms of the disorder appear.

Scientists discover major clue in long-term memory making
You may remember the color of your loved one's eyes for years.

Mutant prions help cells foil harmful protein misfolding
Misfolded proteins are implicated in many incurable neurological diseases. A new and improved understanding of how naturally occurring variants keep proteins from bunching up and spreading provides more options for developing a treatment than scientists had realized.

Ethnic minorities are 'silent sufferers' of chronic fatigue syndrome
Chronic fatigue syndrome (CFS) is characterized by unexplained and debilitating tiredness and is associated with headaches, disrupted sleep, muscle pain and difficulty in concentrating.

Bone societies from Australia, Colombia and Poland win grants for educational projects
The International Osteoporosis Foundation announced the winners of the 2011 IOF-AMGEN/GSK Health Professionals Awareness Grants on March 20th at the IOF Worldwide Conference of Osteoporosis Patient Societies in Valencia.

Bulgarian society awarded 2011 IOF Linda Edwards Memorial Award
The Association Women without Osteoporosis of Bulgaria has been announced the winner of the 2011 IOF Linda Edwards Memorial Award.

New imaging technique provides rapid, high-definition chemistry
With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality.

Climate change hits home
Direct experience of extreme weather events increases concern about climate change and willingness to engage in energy-saving behavior, according to a new research paper published in the first edition of the journal Nature Climate Change this week.
