The gene for tryptophan hydroxylase-2, which makes the brain chemical serotonin, is being linked to increased susceptibility to the placebo effect, based on an experiment at Uppsala University. The effect of the gene may extend to other conditions where the amygdala is involved, such as phobias, pain disorders and even depression.

MIT researchers have unveiled a new type of silicon solar cell that could be 15% more efficient and cost less than currently used solar cells.(Lirong Zeng)It combines a highly effective reflector on the back of a solar cell with an antireflective coating on the front. This helps trap red and near-infrared light, which can be used to make electricity, in the silicon. (Source: http://www.technologyreview.com/energy/21755/?a=f)

The GAMES group at the University of Alberta is using AI to develop the next generation of interactive video games. Today, many video games create only an illusion of intelligence, using a few programming tricks. But in the not-so-distant future, game bots will routinely use sophisticated AI techniques to shape their behavior, the researchers say.With their PaSSAGE game, the computer learn players' interests and preferences and molds the story to ...

Scientists from Texas A&M University and University of Houston have discovered that by building a certain type of piezoelectric material to a specific thickness (about 21 nanometers), you can boost its energy production by 100 percent. A component built with optimally sized piezoelectric for maximum energy conversion could potentially run a cell phone based on vibrations from your voice, or other mobile devices, perhaps based on motion or typing o...

Vitamin D deficiency increases the risk of heart disease and is linked to other, well-known heart disease risk factors such as high blood pressure, obesity, and diabetes, says researcher James H. O'Keefe, MD, director of preventive cardiology at the Mid America Heart Institute in Kansas City, Mo.

(PhysOrg.com) -- The detection of cancer-associated proteins, or biomarkers, in blood samples is a potentially powerful tool for early diagnosis of cancer and monitoring of cancer treatment. A team led by researchers at Stanford University and the University of California, Santa Cruz, has developed a compact prototype detector that uses magnetic nanotechnology to spot cancer-associated proteins in a human blood serum sample with much higher sensit...

(PhysOrg.com) -- The nanobubbles that develop on submerged surfaces should not really be able to exist. Because of the enormous internal pressure, they should disappear within a short time. Nevertheless, they sometimes last for hours: an unexplained phenomenon.

Neuroscientists have presented evidence that they can create a "body swapping" illusion by using VR helmets, showing that the brain, when tricked by optical and sensory illusions, can quickly adopt any other human form, no matter how different, as its own.Based on virtual-reality experiments, the technique could have a profound effect on a range of therapeutic techniques. In these studies, researchers create avatars that mimic a person's every mov... More

Yale University researchers have developed a light-driven nanoresonator that uses a modulator driven by light, not electrons. The technology could be used to develop opto-mechanical switches that can reroute optical signals, achieving far faster performance with simpler systems than by first converting to an electronic router.Such devices could also be used to create very sensitive chemical sensors.

Pacific BioSciences says that by 2013, it could sequence a person's entire genome in half an hour with 99.999 per cent accuracy for under $1000. The new technique involves attaching a different coloured fluorescent dye to each of the four types of nucleotide and watching these flash as they are incorporated into the strand (see diagram). The sequence of coloured flashes in this molecular fireworks display indicates the order in which the nucleotid... More

Tasimelteon, an investigational drug to combat insomnia, helped people cope with disrupted sleep-wake cycles in a study involving healthy individuals who were told to go to sleep five hours earlier than normal at a sleep clinic, Brigham and Women's Hospital researchers reported in Lancet.By activating the MT1 and MT2 melatonin receptors, these agents appear to help the body shift its circadian rhythms to align with altered sleep-wake behaviors.
