Primates' social intelligence overestimated: Primates groom others if afraid they'd lose fight Posted: 11 Jan 2010 08:00 AM PST The grooming behavior displayed by primates is due to less rational behavior than often thought. According to a computer model, one basic rule explains all possible grooming patterns: individuals will groom others if they're afraid they'll lose from them in a fight.

Paper strips can quickly detect toxin in drinking water Posted: 11 Jan 2010 08:00 AM PST A strip of paper infused with carbon nanotubes can quickly and inexpensively detect a toxin produced by algae in drinking water.

Camera traps yield first-time film of tigress and cubs Posted: 11 Jan 2010 08:00 AM PST Camera traps deep in the Sumatran jungle have captured first-time images of a rare female tiger and her cubs, giving researchers unique insight into the elusive tiger's behavior. Specially designed video cameras installed by WWF-Indonesia's researchers caught the mother tiger and her cubs on film as they stopped to sniff and check out the camera trap.

Predicting survival for pulmonary arterial hypertension patients Posted: 11 Jan 2010 08:00 AM PST Setting out to determine the survival of patients with pulmonary arterial hypertension (PAH), researchers have discovered that an equation used for more than 20 years to predict survival is outdated. Accordingly, they developed a new survival prediction equation that will impact clinical practice and the drug development process.

Early lessons from the H1N1 pandemic: Critical illness in children unpredictable but survivable Posted: 11 Jan 2010 08:00 AM PST Lessons learned from the first 13 children at Johns Hopkins Children's Center to become critically ill from the H1N1 virus show that although all patients survived, serious complications developed quickly, unpredictably, with great variations from patient to patient and with serious need for vigilant monitoring and quick treatment adjustments.

'Fossil' fireballs from supernovae discovered by Suzaku observatory Posted: 11 Jan 2010 05:00 AM PST Studies of two supernova remnants using the Japan-US Suzaku observatory have revealed never-before-seen embers of the high-temperature fireballs that immediately followed the explosions. Even after thousands of years, gas within these stellar wrecks retain the imprint of temperatures 10,000 times hotter than the sun's surface.

Deep brain stimulation successful for treatment of severely depressive patient Posted: 11 Jan 2010 05:00 AM PST Neurosurgeons and psychiatrists have for the first time successfully treated a patient suffering from severe depression by stimulating the habenula, a tiny nerve structure in the brain.

Coal from mass extinction era linked to lung cancer mystery Posted: 11 Jan 2010 05:00 AM PST The volcanic eruptions thought responsible for Earth's largest mass extinction -- which killed more than 70 percent of plants and animals 250 million years ago -- is still taking lives today. That's the conclusion of a new study showing, for the first time, that the high silica content of coal in one region of China may be interacting with volatile substances in the coal to cause unusually high rates of lung cancer.

A virtual liver, a better chance of life Posted: 11 Jan 2010 05:00 AM PST Surgeons can now use 3-D, accurate images of the liver to rehearse keyhole tumor removal before real surgery -- reducing the risk to the patient and enabling them to take expert advice.

Quantum fluctuations are key in superconductors, researchers find Posted: 11 Jan 2010 05:00 AM PST New experiments on a recently discovered class of iron-based superconductors suggest that the ability of their electrons to conduct electricity without resistance is directly connected with the magnetic properties of those electrons. The results by U.S. and Chinese physicists bolster theories that high-temperature superconductivity in materials called "iron pnictides" arises from quantum magnetic fluctuations.

New treatment for hyperactivity in children: Thought-operated computer system Posted: 11 Jan 2010 05:00 AM PST A new thought-operated computer system which can reduce the symptoms of Attention Deficit Hyperactivity Disorder (ADHD) in children is being be rolled out across the UK.

Coral can recover from climate change damage, new research suggests Posted: 10 Jan 2010 02:00 PM PST A new study by scientists in the UK provides the first evidence that coral reefs can recover from the devastating effects of climate change. The research shows for the first time that coral reefs located in marine reserves can recover from the impacts of global warming.

Brain imaging may help diagnose autism Posted: 10 Jan 2010 02:00 PM PST Children with autism spectrum disorders (ASDs) process sound and language a fraction of a second slower than children without ASDs, and measuring magnetic signals that mark this delay may become a standardized way to diagnose autism. While more work remains to be done, this pattern of delayed brain response may be refined into the first imaging biomarker for autism.

Vitamin bombs for baby fish Posted: 10 Jan 2010 02:00 PM PST Scientists have set themselves the goal of exploiting the advantages of a special type of zooplankton on a large scale called Copepods.

Vaccine appears to 'mop up' leukemia cells Gleevec leaves behind Posted: 10 Jan 2010 02:00 PM PST Preliminary studies show that a vaccine made with leukemia cells may be able to reduce or eliminate the last remaining cancer cells in some chronic myeloid leukemia patients taking the drug Imatinib mesylate (Gleevec).

Researchers study microbes in cattle to unlock metabolic disease mysteries Posted: 10 Jan 2010 02:00 PM PST Switching from warm-season grasses to cool-season forages can give livestock a belly ache, in some cases a deadly one, according to scientists. Scientists are using state-of-the-art technology -- metagenomics -- to determine how changes in diet affect microbial communities in the digestive tract of cattle and how these changes may increase risk of disease.

Second-hand pollution Posted: 10 Jan 2010 02:00 PM PST Everything from simple tools to complete factories is available for export from the US and Europe to the developing world. At first site, such "recycling" of equipment sounds laudable, but a European research team argues that such exports are slowing the adoption of more environmentally friendly and non-polluting technology across the globe.

Most Earth-like exoplanet ever found started out as a gas giant Posted: 10 Jan 2010 08:00 AM PST The most Earth-like planet yet found around another star may be the rocky remains of a Saturn-sized gas giant.

Micro RNAs can turn genes off Posted: 10 Jan 2010 08:00 AM PST RNA molecules are the mobile messengers of genes. They carry information on the production of proteins from the DNA to the ribosomes. In addition to these messenger RNAs all living beings have micro RNAs that can hinder the messenger RNAs and thus the production of proteins. Biologists have now discovered that such micro RNAs also come into direct contact with genes, effectively turning off the genes in the process.

Targeting cancerous vessels Posted: 10 Jan 2010 08:00 AM PST By lowering the level of a neuronal protein, researchers halted the growth of blood vessels that tumors rely on for survival.

Ipratropium bromide may increase risk for cardiovascular events Posted: 10 Jan 2010 08:00 AM PST Patients taking ipratropium bromide, an anticholinergic used in the treatment of COPD, may be at an increased risk for cardiovascular events (CVE), including heart failure.

What connects the elderly and sports people? Smart sensor technology Posted: 10 Jan 2010 08:00 AM PST Innovative smart sensing devices promise to boost mobility and quality of life for the elderly, reduce healthcare costs and even give sports people an edge through more effective training.

Hispanic elderly more likely than whites to live in inferior nursing homes Posted: 10 Jan 2010 08:00 AM PST Researchers have determined that Hispanic residents are more likely than whites to live in nursing homes of poor quality.

How plants 'feel' the temperature rise Posted: 10 Jan 2010 02:00 AM PST Plants are incredibly temperature sensitive and can perceive changes of as little as one degree Celsius. Now, new research shows how they not only 'feel' the temperature rise, but also coordinate an appropriate response -- activating hundreds of genes and deactivating others; it turns out it's all about the way that their DNA is packaged.

Pediatric cancer survivors at risk for diseases that predispose them to heart disease Posted: 10 Jan 2010 02:00 AM PST Survivors of pediatric cancer are at greater risk for high cholesterol, diabetes and high blood pressure, all of which predispose them to heart disease. These risk factors for heart disease are being found at an earlier age than in the general population, according to new research.

Old hay and Alpine ibex horns reveal how grasslands respond to climate change Posted: 10 Jan 2010 02:00 AM PST To better understand how grassland ecosystems respond to a warming climate and rising levels of carbon dioxide -- particularly with respect to the plants' water use -- resourceful scientists have captured telling time series from the proverbially fleeting grass. Grassland researchers analyzed specimens of hay from the British lowlands dating back as far as 150 years, together with nearly 70 years of grazing as recorded in the horns of Alpine ibex, correlating these data with climate records.

SNPs in C-reactive protein are not associated with increased risk of cancer Posted: 10 Jan 2010 02:00 AM PST Gene variants associated with increased circulating levels of C-reactive protein, a marker of inflammation, are not associated with an increased risk of cancer, according to a new study.

New record in the area of prime number decomposition of cryptographically important numbers Posted: 10 Jan 2010 02:00 AM PST An international team of scientists has obtained the prime factors of the RSA challenge number RSA-768, using the Number Field Sieve.

All sustainable transportation subsidies shouldn't be created equal, experts say Posted: 10 Jan 2010 02:00 AM PST When it comes to pumping up the appeal of plug-in hybrid electric vehicles, some regions are more ripe for the cars than others, and some consumers' buttons need more pushing than others -- an important policy distinction when shaping subsidies, two energy policy experts say.
