A new way to weigh planets (October 23, 2010) -- Astronomers have developed a new way to weigh the planets in our solar system -- using radio signals from the small spinning stars called pulsars. ... > full story
'Lubricin' molecule discovered to reduce cartilage wear (October 23, 2010) -- A team of researchers in North Carolina has discovered that lubricin, a synovial fluid glycoprotein, reduces wear to bone cartilage, a result that has implications for the treatment of osteoarthritis. ... > full story
Efforts underway to rescue vulnerable bananas, giant swamp taro, other Pacific Island crops (October 23, 2010) -- Hoping to save the vulnerable varieties of bananas painted by the artist Paul Gauguin, rare coconuts, and 1,000 other unique varieties of staple fruit and vegetable crops across the Pacific, crop specialists from nine islands have launched a major effort to preserve the indigenous diversity of foods that are deemed critical to combating diet-related health problems. ... > full story
Factor boosting leukemia's aggressiveness identified (October 23, 2010) -- Chronic lymphocytic leukemia cells survive and thrive not just by their own innate wiles, but by also acquiring aid and support from host cells in their surrounding environment. In a new study, researchers identify a particular relationship that can promote notably aggressive leukemias and lymphomas. ... > full story
Nanotube thermopower: Efforts to store energy in carbon nanotubes (October 23, 2010) -- Researchers from Massachusetts have found a way to store energy in thin carbon nanotubes by adding fuel along the length of the tube, chemical energy, which can later be turned into electricity by heating one end of the nanotubes. ... > full story
Authoritarian behaviour leads to insecure people, Spanish study finds (October 23, 2010) -- Researchers have identified the effects of the way parents bring up their children on social structure in Spain. Their conclusions show that punishment, deprivation and strict rules impact on a family's self esteem. ... > full story
Scientists open electrical link to living cells (October 23, 2010) -- The Terminator. The Borg. The Six Million Dollar Man. Science fiction is ripe with biological beings armed with artificial capabilities. In reality, however, the clunky connections between living and non-living worlds often lack a clear channel for communication. Now scientists have designed an electrical link to living cells engineered to shuttle electrons across a cell's membrane. This direct channel could yield cells that can read and respond to electronic signals, or efficiently transfer sunlight into electricity. ... > full story
Risk gene for severe heart disease discovered (October 23, 2010) -- A common variant of the cardiovascular heat shock protein gene, HSPB7, was found to increase risk for dilated cardiomyopathy by almost 50 percent. ... > full story
First implanted device to treat balance disorder developed (October 23, 2010) -- A University of Washington Medical Center patient is the world's first recipient of a device that aims to quell the disabling vertigo associated with Meniere's disease. The clinicians who developed the implantable device hope that success in a 10-person surgical trial of Meniere's patients will lead to exploration of its usefulness against other common balance disorders that torment millions of people worldwide. ... > full story
Risk markers for Alzheimer’s disease (October 23, 2010) -- Many proposed drugs for Alzheimer’s disease have been tested, but have not proved good enough. The reason could be because they have been tested on patients who have already developed dementia. At this point it could be too late to start medication, because the disease is now believed to begin decades before a patient displays clear symptoms. So how can we identify the patients who do not yet have Alzheimer’s, but who are at high risk of developing the disease? ... > full story
Short-range scattering in quantum dots: Discovery advances novel devices (October 23, 2010) -- Chinese researchers have described a new breakthrough in understanding the way electrons travel around quantum dots. This might lead to promising new fabrication methods of novel quantum devices. ... > full story
Airbags reduce risk of kidney injury in car crashes, study finds (October 23, 2010) -- Occupants in motor vehicles with airbags are much less likely to suffer kidney or renal damage in a crash than are occupants in vehicles without airbags, according to a new study. ... > full story
