| A pack of walnuts a day keeps the fertility specialist away? Posted: 15 Aug 2012 12:16 PM PDT After eating 75 grams of walnuts every day for 12 weeks, healthy young men aged 21 to 35 saw increased sperm vitality, motility, and morphology, researchers report. |
| First direct observations of quantum effects in an optomechanical system Posted: 15 Aug 2012 11:20 AM PDT Using a unique optical trapping system that provides ensembles of ultracold atoms, scientists have recorded the first direct observations of distinctly quantum optical effects -- amplification and squeezing -- in an optomechanical system. Their findings point the way toward low-power quantum optical devices and enhanced detection of gravitational waves among other possibilities. |
| Karate black belts' white matter shows how a powerful punch comes from the brain Posted: 15 Aug 2012 07:28 AM PDT Brain scans have revealed distinctive features in the brain structure of karate experts, which could be linked to their ability to punch powerfully from close range. Researchers found that differences in the structure of white matter -- the connections between brain regions -- were correlated with how black belts and novices performed in a test of punching ability. |
| When it comes to food, chimps only think of themselves Posted: 15 Aug 2012 06:32 AM PDT A sense of fairness is an important part of human behavior, yet a research team found it did not evolve from our closest living relatives. The study tested whether our great ape relatives, the chimpanzees and bonobos, have a sense of fairness like humans. |
| Asymmetric warfare between earwigs explored Posted: 15 Aug 2012 05:32 AM PDT Symmetrical looks are highly prized in the animal kingdom, but according to biologists studying an insect called the maritime earwig, asymmetry might come with its own perks. |
| This is not a pipe: Curious dark Pipe Nebula seen as never before Posted: 15 Aug 2012 05:27 AM PDT Just as René Magritte wrote "This is not a pipe" on his famous painting, this is also not a pipe. It is however a picture of part of a vast dark cloud of interstellar dust called the Pipe Nebula. By coincidence this image is appearing on the 45th anniversary of the painter's death. |
| Flexible snake armor could inspire abrasion-resistant materials Posted: 15 Aug 2012 05:27 AM PDT Snakes are highly specialized legless animals, which have evolved around 150 million years ago. Although without extremities their body is exposed to constant friction forces. Snake skin could inspire systems in engineering with minimized abrasion. |
| New toilet developed: Needs no connection to water supply Posted: 15 Aug 2012 05:27 AM PDT There are 2.6 billion people in the world who have no access to a decent toilet. A new toilet model will provide a sanitary solution that ensures human dignity and hygiene, while also being environment-friendly and economically feasible. All for less than five cents per day and person. |
