Competition puts the brakes on body evolution in island lizards Posted: 22 Jun 2010 05:00 PM PDT Millions of years before humans began battling it out over beachfront property, a similar phenomenon was unfolding in a diverse group of island lizards. Often mistaken for chameleons or geckos, Anolis lizards fight fiercely for resources, responding to rivals by doing push-ups and puffing out their throat pouches. But anoles also compete in ways that shape their bodies over evolutionary time, says a new study.

Ear tubes appear safe for children with cochlear implants Posted: 22 Jun 2010 05:00 PM PDT A history of ear tubes to treat infections does not appear to adversely affect children with cochlear implants, regardless of whether the tubes are left in place or removed before implantation, according to a new study.

Citizen science: Birders contribute valuable data on invasive plant species Posted: 22 Jun 2010 05:00 PM PDT In an effort to assess ties between birds' feeding habits and the spread of nonnative invasive plants, researchers provided ornithologists from four US states with questionnaires on daily bird-plant encounters. The 1,143 unique interactions reported by the birders laid the groundwork for a study on the role of native birds in the seed dispersal of invasive plants throughout the US.

People who suppress anger are more likely to become violent when drunk Posted: 22 Jun 2010 05:00 PM PDT A new study reveals that drunkenness increases the risk for violent behavior, but only for individuals with a strong inclination to suppress anger.

The finding could lead to earlier detection of schizophrenia and enable better prevention and treatment.

Portable media players associated with short-term hearing effects Posted: 22 Jun 2010 02:00 PM PDT Temporary changes in hearing sensitivity are associated with potential harmful effects of listening to an MP3 player, according to a new study.

Jumbo jellyfish or massive star? Posted: 22 Jun 2010 02:00 PM PDT Some might see a blood-red jellyfish in a forest of seaweed, while others might see a big, red eye or a pair of lips. In fact, the red-colored object in this new infrared image from NASA's Wide-field Infrared Survey Explorer (WISE) is a sphere of stellar innards, blown out from a humongous star.

Puberty and sleep regulation can influence alcohol use during early adolescence Posted: 22 Jun 2010 02:00 PM PDT Alcohol is known to disrupt sleep, but little is known about alcohol use and sleep problems during adolescence. A new study has found that puberty is related to sleep problems and later bedtimes, which were in turn associated with alcohol use.

World's first plastic antibodies in live organisms: Stop spread of bee venom in mice Posted: 22 Jun 2010 11:00 AM PDT Researchers have developed the first "plastic antibodies" successfully employed in live organisms -- stopping the spread of bee venom through the bloodstream of mice.

Alcohol consumption lowers risk of developing several arthritic conditions, study finds Posted: 22 Jun 2010 11:00 AM PDT Alcohol consumption is associated with a significantly reduced risk of developing several arthritic conditions including rheumatoid arthritis, osteoarthritis, reactive arthritis, psoriatic arthritis and spondylarthropathy, according to results of a new study.

Studying cells in 3-D could reveal new cancer targets Posted: 22 Jun 2010 11:00 AM PDT Showing movies in 3-D has produced a box-office bonanza in recent months.

Looking at cells in 3-D, the research team concluded, yields more accurate information that could help develop drugs to prevent cancer's spread.

Bacteria in the nose and throat: Most comprehensive comparative analysis Posted: 22 Jun 2010 11:00 AM PDT Scientists have completed the most comprehensive comparative analysis to date of bacterial communities inhabiting the human nose and throat, which could provide new insights into why some individuals become colonized with pathogens while others do not.

Bone replacement from laser melting Posted: 22 Jun 2010 11:00 AM PDT In a medical emergency, a puncture of the cranium is commonly treated with an implant. While replacements made of titanium merely plug holes, a new kind of degradable implant stimulates the body to regenerate itself: It is custom-fit and disappears to the same extent that the bone regrows.

Some types of arousal can lead to unhealthy choices, study finds Posted: 22 Jun 2010 11:00 AM PDT You might want to avoid food shopping right after a heavy workout or drinking after an intense day of high-powered negotiations, according to a new study.

Chimpanzee gangs kill for land, new study shows Posted: 22 Jun 2010 08:00 AM PDT Bands of chimpanzees violently kill individuals from neighboring groups in order to expand their own territory, according to a 10-year study of a chimp community in Uganda that provides the first definitive evidence for this long-suspected function of this behavior.

Early-life exposure to BPA may affect testis function in adulthood Posted: 22 Jun 2010 08:00 AM PDT Exposure to environmental levels of the industrial chemical bisphenol A, or BPA, in the womb and early life may cause long-lasting harm to testicular function, according to a new study conducted in animals.

Agricultural scientists take a long look at livestock and locoweed Posted: 22 Jun 2010 05:00 AM PDT Keeping livestock away from poisonous locoweed during seasons when it's a forage favorite is one way ranchers can protect their animals and their profits, according to researchers.

Can multiple sclerosis attacks be minimized in a war zone? Posted: 22 Jun 2010 05:00 AM PDT An earlier study has shown that the stress of the Second Lebanon War in Israel increased the frequency of attacks in multiple sclerosis patients. The present study reveals that a potential way to minimize MS exacerbation is by directly coping with the situation.

Novel pathway may open doors for new blood pressure treatments Posted: 22 Jun 2010 02:00 AM PDT Researchers have found that increasing certain proteins in the blood vessels of mice, relaxed the vessels, lowering the animal's blood pressure. The study provides new avenues for research that may lead to new treatments for hypertension.

Ocean stirring and plankton patchiness revealed by computer simulation Posted: 22 Jun 2010 02:00 AM PDT Computer simulations show how oceanic stirring and mixing influence the formation and dynamics of plankton patches in the upper ocean. Researchers applied the methods of synchronization theory -- previously used to explain such phenomena as the coordinated flashing of fireflies along whole riverbanks. Initially they studied the balance between localized increases in phytoplankton populations and small-scale mixing, such as that due to breaking waves, in creating patches. Patchiness was found to persist despite the mixing which might be expected to smooth out the patches by blending them together.

Building to withstand hurricanes Posted: 22 Jun 2010 02:00 AM PDT An expert in the design of low-rise buildings for extreme winds and hurricane hopes her phone won't ring much this hurricane season. It's already been busy with requests for information about best building design and construction practices to reduce wind pressures on building surfaces.

Electronic health records could give rise to more liability risk, experts argue Posted: 22 Jun 2010 02:00 AM PDT Electronic health record systems likely will soon become a fixture in medical settings. Although benefits of bringing information technology to health records can be substantial, EHR systems also give rise to increased liability risks for health care providers due to possible software or hardware problems or user errors, experts say.

Greater religiosity during adolescence may protect against developing problem alcohol use Posted: 21 Jun 2010 11:00 PM PDT Phenotypes are measurable and/or observable traits or behaviors. The heritability of an alcohol-related phenotype depends upon the social environment within which it is measured, such as urbanicity, marital status, or religiosity. A new study of the effects of religiosity on the genetic variance of problem alcohol use in males and females has found that religiosity can moderate genetic effects on problem alcohol use during adolescence but not during early adulthood.

Hubble captures bubbles and baby stars Posted: 21 Jun 2010 09:00 PM PDT A spectacular new Hubble Space Telescope image — one of the largest ever released of a star-forming region — highlights N11, part of a complex network of gas clouds and star clusters within our neighboring galaxy, the Large Magellanic Cloud.
