Water is 'designer fluid' that helps proteins change shape, scientists say
Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought.

GIANT-Coli: A novel method to quicken discovery of gene function
Think researchers know all there is to know about Escherichia coli, commonly known as E. coli? Think again. "E. coli has more than four thousand genes, and the functions of one-fourth of these remain unknown," says Dr. Deborah Siegele, a biology professor at Texas A&M University whose laboratory specializes in carrying out research using the bacterium.

Improved reaction data heat up the biofuels harvest
High food prices, concern over dwindling supplies of fossil fuels and the desire for clean, renewable energy have led many to seek ways to make ethanol out of cellulosic sources such as wood, hay and switchgrass.

Scientists a step closer to producing fuel from bacteria
Scientists at the University of Sheffield have shown how bacteria could be used as a future fuel. The research, published in the journal Bioinformatics, could have significant implications for the environment and the way we produce sustainable fuels in the future.

Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system.

Aphids are sentinels of climate change
Aphids are emerging as sentinels of climate change, researchers at BBSRC-supported Rothamsted Research have shown. One of the UK's most damaging aphids - the peach-potato aphid (Myzus persicae) - has been found to be flying two weeks earlier for every 1 degree C rise in mean temperature for January and February combined.

Invest in your family's health by budgeting for nutrient-rich foods
Times are tough for many families and schools - so those food dollars need to work hard by providing plenty of nutrition. Many nutrient-rich foods such as milk, are a good economic and nutritional value because they pack in many essential nutrients at a low cost per serving.

Study finds connections between genetics, brain activity and preference
A team of researchers from Massachusetts General Hospital (MGH) has used brain imaging, genetics and experimental psychology techniques to identify a connection between brain reward circuitry, a behavioral measurement of preference and a gene variant that appears to influence both.

Quantum chaos unveiled?
A University of Utah study is shedding light on an important, unsolved physics problem: the relationship between chaos theory - which is based on 300-year-old Newtonian physics - and the modern theory of quantum mechanics.

Hot peppers really do bring the heat
Chili peppers can do more than just make you feel hot, reports a study in the August 1 Journal of Biological Chemistry; the active chemical in peppers can directly induce thermogenesis, the process by which cells convert energy into heat.

Ricin's Deadly Action Revealed by Glowing Probes
A new chemical probe can rapidly detect ricin, a deadly poison with no known antidote that is feared to be a potential weapon for terrorists and cannot quickly be identified with currently available tests.

Caltech neurobiologists discover individuals who 'hear' movement
Individuals with synesthesia perceive the world in a different way from the rest of us. Because their senses are cross-activated, some synesthetes perceive numbers or letters as having colors or days of the week as possessing personalities, even as they function normally in the world.

NYU researchers demonstrate activity of mebendazole in metastatic melanoma
Researchers at the NYU Cancer Institute and the Ronald O. Perelman Department of Dermatology have identified mebendazole, a drug used globally to treat parasitic infections, as a novel investigational agent for the treatment of chemotherapy-resistant malignant melanoma.

New technology could lead to camera based on human eye
Digital cameras have transformed the world of photography. Now new technology inspired by the human eye could push the photographic image forward even more by producing improved images with a wider field of view.

When it comes to abstinence teens, adults aren't speaking the same language
Abstinence can mean different things to adolescents than to adults. That's one reason why abstinence-only programs do not have strong effects in preventing teenage sexual activity, according to new University of Washington research.

Comprehensive treatment of extensively drug-resistant TB works, study finds
The death sentence that too often accompanies a diagnosis of extensively drug-resistant tuberculosis (XDR-TB) can be commuted if an individualized outpatient therapy program is followed - even in countries with limited resources and a heavy burden of TB.

Recipe for cell reprogramming adds protein
A drug-like molecule called Wnt can be substituted for the cancer gene c-Myc, one of four genes added to adult cells to reprogram them to an embryonic-stem-cell-like state.

New survey: 82 percent of Americans think health care system needs major overhaul
Americans are dissatisfied with the U.S. health care system and 82 percent think it should be fundamentally changed or completely rebuilt, according to a new survey released today by The Commonwealth Fund. Also today, The Commonwealth Fund Commission on A High Performance Health System released a report outlining what an ideally organized U.S. health care system would look like, and detailing strategies that could create that organized, efficient health care system while simultaneously improving care and cutting costs.

Treatment outcomes highlight dangers of extensively drug-resistant tuberculosis
In a retrospective study of 174 tuberculosis patients treated at National Jewish Health (formerly National Jewish Medical and Research Center), patients with extensively-drug-resistant tuberculosis (XDR-TB) were almost eight times as likely to die as patients with multi-drug resistant tuberculosis (MDR-TB).

Lack of time on tummy shown to hinder achievement
The American Physical Therapy Association (APTA) is urging parents and caregivers to ensure that babies get enough "tummy time" throughout the day while they are awake and supervised, in light of a recent survey of therapists who say they've noticed an increase in motor delays in infants who spend too much time on their backs while awake.

Scripps research team unravels new cellular repair mechanism
The cell cycle, which allows cells to replicate their DNA and produce new cells, is controlled by a complex concert of enzymes and other components. In addition there are "checkpoint" mechanisms that can block continuation of the process if something goes amiss.
