| Posted: 31 Dec 2012 03:06 PM PST As if space travel was not already filled with enough dangers, a new study shows that cosmic radiation -- which would bombard astronauts on deep space missions to places like Mars -- could accelerate the onset of Alzheimer's disease. |
| Jellyfish experts show increased blooms are a consequence of periodic global fluctuations Posted: 31 Dec 2012 03:06 PM PST Blooms, or proliferations, of jellyfish can show a substantial, visible impact on coastal populations -- clogged nets for fishermen, stinging waters for tourists, even choked cooling intake pipes for power plants -- and recent media reports have created a perception that the world's oceans are experiencing trending increases in jellyfish. Now, a new multinational collaborative study suggests these trends may be overstated, finding that there is no robust evidence for a global increase in jellyfish over the past two centuries. |
| Did Lucy walk on the ground or stay in the trees? Posted: 31 Dec 2012 01:10 PM PST Researchers have investigated tree-climbing behavior of modern hunter-gatherers to elucidate our fossil ancestors' terrestrial versus arboreal preferences. |
| Differences in generic pill characteristics may lead to interruptions in essential medication use Posted: 31 Dec 2012 01:10 PM PST Researchers have found that some patients who receive generic drugs that vary in their color are over 50 percent more likely to stop taking the drug, leading to potentially important and potentially adverse clinical effects. |
| As climate warms, bark beetles march on high-elevation forests Posted: 31 Dec 2012 01:10 PM PST In a new study, scientists report a rising threat to the whitebark pine forests of the northern Rocky Mountains as native mountain pine beetles climb ever higher, attacking trees that have not evolved strong defenses to stop them. |
| Paired CT scans catch chemo-killing of liver tumors in real time Posted: 31 Dec 2012 08:05 AM PST Using two successive pairs of specialized CT scans, a team of radiologists has produced real-time images of liver tumors dying from direct injection of anticancer drugs into the tumors and their surrounding blood vessels. |
| Hydrogen peroxide vapor enhances hospital disinfection of superbugs Posted: 31 Dec 2012 08:05 AM PST Infection control experts have found that a combination of robot-like devices that disperse a bleaching agent into the air and then detoxify the disinfecting chemical are highly effective at killing and preventing the spread of multiple-drug-resistant bacteria, or so-called hospital superbugs. |
