Oddball stars explained

(PhysOrg.com) -- New observations solve longstanding mystery of tipped rotation. In addition to shedding light on how binary stars form, the explanation knocks down a possible challenge to Einstein's theory of relativity.

Putting a Strain on Nanowires Could Yield Colossal Results

(PhysOrg.com) -- In finally answering an elusive scientific question, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the selective placement of strain can alter the electronic phase and its spatial arrangement in correlated electron materials. This unique class of materials is commanding much attention now because they can...

Scientists begin Southeast Asia study of aerosols linked to global warming

NRL's Marine Meteorology Division has deployed the Mobile Atmosphere, Aerosol, and Radiation Characterization Observatory (MAARCO) to the National University of Singapore to begin the first comprehensive radiation and aerosol assessment in the Maritime Continent region. NRL is leading the effort to investigate ways in which to infer larger aerosol and visibility features from limited data sets,...

Insulin-Linked Genes Tied to Body's Internal Clock (HealthDay)

HealthDay - THURSDAY, Sept. 17 (HealthDay News) -- Genes that regulate insulin in the body also play a role in the timing of the body's sleep-wake cycle, researchers say, and this finding that could potentially lead to treatments for disorders that arise when circadian rhythms are disrupted.

Buffer gas cooling could open up the field of ultracold physics

(PhysOrg.com) -- "Scientists have been making Bose-Einstein Condensates [BECs] for nearly 15 years," Charlie Doret tells PhysOrg.com. "Essentially all BEC research to date, however, begins with laser cooling. Unfortunately, laser cooling is impractical for some atoms, and it is especially difficult with molecules, limiting the scope of new research."

GPs' gut feelings defined

'Gut feelings' experienced by GPs play a substantial role in their diagnostic reasoning process, but always in combination with analytical reasoning. Gut feelings can be separated into the sense of alarm and the sense of reassurance. Researchers writing in the open access journal BMC Family Practice worked with 27 medical opinion leaders to closely define the concepts, which will allow future...

Impact of renewable energy on our oceans must be investigated, say scientists

Scientists from the Universities of Exeter and Plymouth are today calling for urgent research to understand the impact of renewable energy developments on marine life. The study, now published in the Journal of Applied Ecology, highlights potential environmental benefits and threats resulting from marine renewable energy, such as off-shore wind farms and wave and tidal energy conversion devices.

Lessons for Obama in study of Bush efforts to 'frame' Iraq war

Wartime leaders have long sought to sway public opinion by "framing" bad news from the frontlines. They present inconvenient facts in an altered format in order to generate support for their policies. A new study from North Carolina State University shows that Bush administration attempts to "frame" casualties from the Iraq War bolstered support for the war effort among certain members of the U.S....

Mechanism related to the onset of various genetic diseases revealed

Researchers at the Department of Biochemistry and Molecular Biology of Universitat Autňnoma de Barcelona (UAB) have revealed the process by which proteins with a tendency to cause conformational diseases such as amyotrophic lateral sclerosis, familial amyloidotic polyneuropathy, familial amyloidotic cardiomyopathy, etc. finally end up causing them.

Metabolic syndrome risk factors drive significantly higher health care costs

Risk factors for metabolic syndrome, such as obesity, high blood pressure, and elevated blood lipid levels, can increase a person's healthcare costs nearly 1.6-fold, or about $2,000 per year. For each additional risk factor those costs rise an average of 24%, according to an illuminating article in a recent issue of Metabolic Syndrome and Related Disorders, a peer-reviewed journal published by...

New research to unravel how nutrients drive toxic 'brown tides' on East Coast

NOAA has awarded Massachusetts-based Woods Hole Oceanographic Institution $120,000 as part of an anticipated three-year, nearly $500,000 project, to determine how nitrogen and phosphorus promote brown tides on the East Coast. Funds were awarded through the interagency Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program.

Regulatory role of key molecule discovered

Discovery by Hebrew University of Jerusalem researchers of an additional role for a key molecule in our bodies provides a further step in world-wide efforts to develop genetic regulation aimed at controlling many diseases, including AIDS and various types of cancers.

Researcher finds natural hydrogel helps heal spinal cord

Research led by a scientist at the Barrow Neurological Institute at St. Joseph's Hospital and Medical Center has shown injecting biomaterial gel into a spinal cord injury site provides significantly improved healing. The project that also included researchers from Purdue University and Arizona State University indicates that a "practical path" to treatment may be found for spinal injury...

Researchers make progress in optimizing solid oxide fuel cells

While our standard of life increases, so does the worldwide energy demand. In this vein, the application of technologies based on fuel cells is put forward as an alternative to the massive consumption of fossil fuels. One of the fuel cells of greatest current interest is the solid oxide one.
