"Basically, any computing device (or switch, or router) that is based on light requires a nonlinear interaction between different light beams, but light doesn't like to do nonlinear stuff. With current technology, you can get efficient nonlinear optical interactions, but the hardware is kind of bulky or very delicate. Not the sort of thing you want to put in a billion devices. What my friends in Barcelona have demonstrated is that it's possible to create a relatively efficient optical nonlinear interaction in a nano-structured metallic surface. "

"Here we show that four days of immersion in nature, and the corresponding disconnection from multi-media and technology, increases performance on a creativity, problem-solving task by a full 50% in a group of naive hikers. Our results demonstrate that there is a cognitive advantage to be realized if we spend time immersed in a natural setting. We anticipate that this advantage comes from an increase in exposure to natural stimuli that are both emotionally positive and low-arousing and a corresponding decrease in exposure to attention demanding technology, which regularly requires that we attend to sudden events, switch amongst tasks, maintain task goals, and inhibit irrelevant actions or cognitions. A limitation of the current research is the inability to determine if the effects are due to an increased exposure to nature, a decreased exposure to technology, or to other factors associated with spending three days immersed in nature."

Dr Simon Archer and his team at Surrey University were particularly interested in looking at the genes that were switched on or off in our volunteers by changes in the amount that we had made them sleep. "We found that overall there were around 500 genes that were affected," Archer explained. "Some which were going up, and some which were going down." What they discovered is that when the volunteers cut back from seven-and-a-half to six-and-a-half hours' sleep a night, genes that are associated with processes like inflammation, immune response and response to stress became more active. The team also saw increases in the activity of genes associated with diabetes and risk of cancer. The reverse happened when the volunteers added an hour of sleep. So the clear message from this experiment was that if you are getting less than seven hours' sleep a night and can alter your sleep habits, even just a little bit, it could make you healthier

ScienceDaily (Jan. 6, 2011) - For parents wanting to reduce the negative influence of TV on their children, the first step is normally to switch off the television set. But a new study suggests that might not be enough. It turns out indirect media exposure, i.e., having friends who watch a lot of TV, might be even more damaging to a teenager's body image.

ScienceDaily (May 9, 2011) - Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods.

"We measured the direction of the body axis in 70 dogs of 37 breeds during defecation (1,893 observations) and urination (5,582 observations) over a two-year period. After complete sampling, we sorted the data according to the geomagnetic conditions prevailing during the respective sampling periods. Relative declination and intensity changes of the MF during the respective dog walks were calculated from daily magnetograms. Directional preferences of dogs under different MF conditions were analyzed and tested by means of circular statistics. Results Dogs preferred to excrete with the body being aligned along the North-south axis under calm MF conditions. This directional behavior was abolished under Unstable MF. The best predictor of the behavioral switch was the rate of change in declination, i.e., polar orientation of the MF. "

It sounds almost too good to be true: a cheap and simple drug that kills almost all cancers by switching off their "immortality". The drug, dichloroacetate (DCA), has already been used for years to treat rare metabolic disorders and so is known to be relatively safe.
