• 06:00 Adding value to data: BioMed Central calls for greater researcher sharing

  Read the story at ScienceDaily
  BMC Research Notes has now shed further light on science's "dark data". The journal is commissioning a large, ongoing collection of educational articles which outline procedures for sharing data that enable the data to be readily re-used by others, which will provide researchers with best practice guidance for exposing their dark data to the light.

• 06:00 Ancient brew masters tapped antibiotic secrets

  Read the story at ScienceDaily
  A chemical analysis of the bones of ancient Nubians shows that they were regularly consuming tetracycline, most likely in their beer. The finding is the strongest evidence yet that the art of making antibiotics, which officially dates to the discovery of penicillin in 1928, was common practice nearly 2,000 years ago. The study finds that it's likely this prehistoric population was using empirical evidence to develop therapeutic agents.

• 06:00 Ants take on Goliath role in protecting trees in the savanna from elephants

  Read the story at ScienceDaily
  Ants are not out of their weight class when defending trees from the appetite of nature's heavyweight, the African elephant, a new study finds. Columns of angered ants will crawl up into elephant trunks to repel the ravenous beasts from devouring tree cover throughout drought-plagued East African savannas, playing a potentially important role in regulating carbon sequestration in these ecosystems.

• 06:00 Capsaicin can act as co-carcinogen, study finds; Chili pepper component linked to skin cancer

  Read the story at ScienceDaily
  New research links capsaicin, a component of chili peppers, to skin cancer. While the molecular mechanisms of the cancer-promoting effects of capsaicin are not clear and remain controversial, the new research has shown a definite connection to formation of skin cancer through various laboratory studies.

• 06:00 Chemists develop simple technique to visualize atomic-scale structures

  Read the story at ScienceDaily
  Researchers have devised a new technique -- using a sheet of carbon just one atom thick -- to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules.

• 06:00 Edible nanostructures: Compounds made from renewable materials could be used for gas storage, food technologies

  Read the story at ScienceDaily
  Sugar, salt, alcohol and a little serendipity led researchers to discover a new class of nanostructures that could be used for gas storage and food and medical technologies. And the compounds are edible. The porous crystals are the first known all-natural metal-organic frameworks (MOFs) that are simple to make. Most other MOFs are made from petroleum-based ingredients, but the new MOFs you can pop into your mouth and eat, and the researchers have.

  Read the story at ScienceDaily
  German scientists have developed a blood test that can reliably detect gene doping even after 56 days. It was previously impossible to prove that an athlete had undergone gene doping.

• 06:00 Head start for migraine sufferers

  Read the story at ScienceDaily
  Psychological migraine treatment gives sufferers a confidence boost in their ability to self-manage their symptoms. For severe migraine sufferers, psychological treatments build on the benefits of drug therapy, according to a new study. A comparison of the effects of various treatment combinations for severe migraine - drug therapy with or without behavioral management - shows that those patients receiving the behavioral management program alongside drug therapy are significantly more confident in their ability to use behavioral skills to effectively self-manage migraines.

• 06:00 Hip dysplasia susceptibility in dogs may be underreported

  Read the story at ScienceDaily
  A study comparing a new method for evaluating a dog's susceptibility to hip dysplasia to the traditional American method has shown that 80 percent of dogs judged to be normal by the traditional method are actually at risk for developing osteoarthritis and hip dysplasia, according to the new method.

• 06:00 Hubble observations of supernova reveal composition of 'star guts' pouring out

  Read the story at ScienceDaily
  Observations made with NASA's newly refurbished Hubble Space Telescope of a nearby supernova are allowing astronomers to measure the velocity and composition of "star guts" being ejected into space following the explosion, according to a new study.

• 06:00 Human unconscious is transferred to virtual characters

  Read the story at ScienceDaily
  Virtual characters can behave according to actions carried out unconsciously by humans. Researchers have created a system which measures human physiological parameters, such as respiration or heart rate, and introduces them into computer designed characters in real time.

• 06:00 Listening to ancient colors: New technique may help restorers identify decades-old pigments

  Read the story at ScienceDaily
  A team of chemists has discovered that a technique known as photoacoustic infrared spectroscopy could be used to identify the composition of pigments used in art work that is decades or even centuries old. Pigments give artist's materials color, and they emit sounds when light is shone on them.

• 06:00 Miniature auto differential helps tiny aerial robots stay aloft

  Read the story at ScienceDaily
  Engineers have created a millionth-scale automobile differential to govern the flight of minuscule aerial robots that could someday be used to probe environmental hazards, forest fires, and other places too perilous for people. Their new approach is the first to passively balance the aerodynamic forces encountered by these miniature flying devices, letting their wings flap asymmetrically in response to gusts of wind, wing damage, and other real-world impediments.
