Canon's Mixed Reality System may speed design cycles
(Phys.org) -- Canon this week announced a new augmented reality system—headset and software. The new system is to allow virtual prototypes to replace physical ones. Three-dimensional computer generated images can instantly change based on the user’s movements. The Mixed Reality (MR) System is being initially promoted as an industrial design tool where, for example, the head-set-wearing user gets to see a computer-generated image of a car on a set of real tires, all in realtime. Two video cameras inside the head-mounted display (HMD), each in front of right and left eyes, capture the real-world video which is sent to a connected computer, processing the merge between real and virtual. -

Lichen survives in space: Could it colonize planets by hitching rides on asteroids?
You can freeze it, thaw it, vacuum dry it and expose it to radiation but still life survives. Research on the International Space Station is giving credibility to theories that life came from outer space -- as well as helping to create better sunscreens.

20:51People with celiac disease struggle with limited food choices, as their condition makes them unable to tolerate gluten, found in wheat and other grains. Researchers have now developed a gluten-free pasta product from green banana flour, which tasters found more acceptable than regular whole wheat pasta. The product has less fat and is cheaper to produce than standard pastas.

20:51The commonly-used epilepsy drug, valproic acid (VPA), can have a highly beneficial effect on some babies born with spinal muscular atrophy (SMA), the number one genetic killer during early infancy. But in about two-thirds of such cases it is either damaging or simply has no effect. Now, for the first time, researchers have found a way to identify which patients are likely to respond well to VPA prior to starting treatment. Their results have major implications, not just for SMA patients, but for other conditions treated with the drug such as migraine and epilepsy, and may even provide the conditions for turning VPA non-responders into responders, the researchers say.

20:49A new study finds that a drop in testosterone levels over time is more likely to result from a man’s behavioral and health changes than by aging.

20:49Studies have consistently reported that women require reading glasses or bifocal lenses earlier than men. According to a recent article, the gender difference is caused by factors other than focusing ability, such as arm length or preferred reading distance, which should be considered when prescribing readers or bifocals.

20:49In testosterone-deficient men, major weight loss was an added benefit of testosterone replacement therapy for most of the patients who participated in a new study.

20:49Even moderate thyroid dysfunction during early pregnancy significantly increases the risk of serious complications, underscoring the need for universal screening in the first trimester, a new study finds.

They may seem strange to some, though the women who use them tend to be enthusiasts: Menstrual cups are a washable, reusable alternative to pads and tampons. Women often choose them because they don't create as much waste as traditional menstrual products; with some models, a woman only needs to buy one cup in her lifetime. In the U.S., the cups are stereotypically associated with women's studies classes, avid environmentalists and Berkeley, Calif. ...

15:44If your father smoked, your genes are likely damaged, and your odds for diseases increased. A new report shows that men who smoke before conception can damage the genes of their offspring. These inherited changes in DNA could render developing offspring susceptible to later diseases, providing evidence for quitting smoking before trying to conceive.

15:44A new assay that uses mitochondrial DNA that mutates faster than nuclear DNA has allowed scientists to identify one of the major animal reservoirs for the ehlichioses, STARI and other tick-borne diseases in the southeastern United States. The animal turned out to be the eastern gray squirrel.

15:44New research suggests there may be a biological reason why fatty and cholesterol-rich foods, like buttery shrimp, fried eggs and burgers and fries are so appealing together. Researchers are using zebrafish to better understand the cellular mechanisms of cholesterol processing and have discovered a surprising link between dietary fat and cholesterol absorption.

15:43A loose group of stars, known for over 180 years but never before studied in detail, has been revealed to be an important new tool in the quest to understand the evolution of stars like the Sun, and in the search for planets like Earth. The star cluster holds great promise for use as a standard gauge in fundamental stellar astrophysics.

15:43How strong are the links in food webs? An experiment demonstrates that they're strong enough for a disturbance to propagate across four trophic levels and two ecosystems. The experiment demonstrates that invasive species such as purple loosestrife could have broad effects on surrounding plant and animal communities, many of them cryptic.
