Researchers test sugary solution to Alzheimer's disease Posted: 28 Feb 2012 04:10 PM PST Slowing or preventing the development of Alzheimer's disease, a fatal brain condition expected to hit one in 85 people globally by 2050, may be as simple as ensuring a brain protein's sugar levels are maintained, according to researchers.

New 'magnetic yeast' marks step toward harnessing Nature's magnetic capabilities Posted: 28 Feb 2012 04:09 PM PST Researchers have developed a method for inducing magnetic sensitivity in an organism that is not naturally magnetic -- yeast. Their technology could potentially be used to magnetize a variety of different cell types in medical, industrial and research applications.

Open your eyes and smell the roses: Activating the visual cortex improves our sense of smell Posted: 28 Feb 2012 03:55 PM PST A new study reveals for the first time that activating the brain's visual cortex with a small amount of electrical stimulation actually improves our sense of smell.

Mysterious electron acceleration explained: Computer simulation identifies source of aurora-causing high-speed electrons in space Posted: 28 Feb 2012 12:22 PM PST A mysterious phenomenon detected by space probes has finally been explained, thanks to a massive computer simulation that was able to precisely align with details of spacecraft observations. The simulation shows that an active region in Earth's magnetotail, where "reconnection" events take place in the magnetic field, is roughly 1,000 times larger than had been thought.

Nowhere to hide: Tigers threatened by human destruction of groundcover Posted: 28 Feb 2012 11:05 AM PST A new study is the first of its kind to systematically investigate the use of different land cover types for tiger habitat.

Overfishing threatens the survival of seabirds Posted: 28 Feb 2012 09:38 AM PST From gannets to seagulls, puffins to penguins, all seabirds suffer the same drop in birth rates when the supply of fish drops to less than a third of maximum capacity. Below the critical level of one third of the fish biomass, the birds — and the stability of the entire ecosystem —- come under threat.

Initial genetic analysis reveals Iceman Ötzi predisposed to cardiovascular disease Posted: 28 Feb 2012 09:38 AM PST The famous Iceman mummy known as Ötzi was genetically predisposed to cardiovascular diseases, according to recent studies. Not only was this genetic predisposition demonstrable in the 5,000-year-old ice mummy, there was also already a symptom in the form of arteriosclerosis, or hardening of the arteries.

World's smallest radio stations: Two molecules communicate via single photons Posted: 28 Feb 2012 07:17 AM PST We know since the dawn of modern physics that although events in our everyday life can be described by classical physics, the interaction of light and matter is down deep governed by the laws of quantum mechanics. Despite this century-old wisdom, accessing truly quantum mechanical situations remains nontrivial, fascinating and noteworthy even in the laboratory. Recently, interest in this area has been boosted beyond academic curiosity because of the potential for more efficient and novel forms of information processing.

Ice Age coyotes were supersized compared to coyotes today, fossil study reveals Posted: 27 Feb 2012 12:27 PM PST Coyotes today are pint-sized compared to their Ice Age counterparts, finds a new fossil study. Between 11,500 and 10,000 years ago -- a mere blink of an eye in geologic terms -- coyotes shrunk to their present size. The sudden shrinkage was most likely a response to dwindling food supply and changing interactions with competitors, rather than warming climate, researchers say.

Could rosemary scent boost brain performance? Posted: 24 Feb 2012 04:43 PM PST Hailed since ancient times for its medicinal properties, we still have a lot to learn about the effects of rosemary. Now researchers have shown for the first time that blood levels of a rosemary oil component correlate with improved cognitive performance.
