Ultra-cold chemistry: First direct observation of exchange process in quantum gas
Considerable progresses made in controlling quantum gases open up a new avenue to study chemical processes. An Austrian research team has now succeeded in directly observing chemical exchange processes in an ultra-cold sample of cesium atoms and Feshbach molecules.
Second 'quantum logic clock' based on aluminum ion is now world's most precise clock
Physicists have built an enhanced version of an experimental atomic clock based on a single aluminum atom that is now the world's most precise clock, more than twice as precise as the previous pacesetter based on a mercury atom. The new aluminum clock would neither gain nor lose one second in about 3.7 billion years.
Sunny Record: Breakthrough for Hybrid Solar Cells
Scientists in Germany have succeeded in developing a method for treating the surface of nanoparticles which greatly improves the efficiency of organic solar cells. The researchers were able to attain an efficiency of 2 percent by using so-called quantum dots composed of cadmium selenide. These measurements, well above the previous efficiency ratings of 1 to 1.8 percent, were confirmed.

Depressed people feel more gray than blue
People with anxiety and depression are most likely to use a shade of gray to represent their mental state. Researchers writing in the open access journal BMC Medical Research Methodology describe the development of a color chart, The Manchester Color Wheel, which can be used to study people's preferred pigment in relation to their state of mind.
Gadgets not related to teenagers' brain pain
Use of most electronic media is not associated with headaches, at least not in adolescents. A study of 1025 13-17 year olds, published in the open access journal BMC Neurology, found no association between the use of computer games, mobile phones or television and the occurrence of headaches or migraines. However, listening to one or two hours of music every day was associated with a pounding head.
Planning to Give Sweets to Your Sweetie? Some Types of Dark Chocolate a Little Healthier than Others

More smokers than non-smokers accept HPV vaccination for their daughters
(American Association for Cancer Research) A parent's existing health habits or behaviors, like cigarette smoking, may influence the likelihood that they will have their daughters vaccinated against HPV.
Few women take tamoxifen to prevent breast cancer
(American Association for Cancer Research) Less than a quarter of one percent of women took tamoxifen in 2000 and 2005 to prevent breast cancer.Further research is recommended to explore explanations for the drug's low use.
Inhibiting serotonin in gut could cure osteoporosis
(Columbia University Medical Center) An investigational drug that inhibits serotonin in the gut, administered orally once daily, effectively cured osteoporosis in mice and rats, reports a new paper in Nature Medicine. Serotonin in the gut has been shown in recent research to stall bone formation. The finding could lead to new therapies that build new bone; most osteoporosis drugs only prevent the breakdown of old bone.
