Kickstarter Launches to Build a Mini-James Webb Space Telescope

As NASA gears up for the launch of its next great space telescope in 2018, a model-making team is asking for help to create miniature versions of the huge observatory for public outreach. The group, MesaTech, which describes itself as a "broadly purposed cooperative founded and managed by our members," launched a Kickstarter campaign asking for $25,000 to produce models of NASA's infrared James Webb Space Telescope (JWST). The group said it has spent four years touring NASA centers with a one-sixth-scale deployable model of the telescope, but the model's large size limits its use.

Weight-Loss Surgery Changes Gut Bacteria

Bariatric surgery may lead to long-term changes in people's gut bacteria that contribute to weight loss following the procedure, a new study from Sweden suggests. Researchers analyzed the gut bacteria of 14 women nearly a decade after they underwent bariatric surgery, also known as weight-loss surgery. Half of the women had undergone a type of surgery called Roux-en-Y gastric bypass, in which doctors create a small pouch out of the top of the stomach and connect it directly to the small intestine.

Fatherhood in Early 20s May Raise Risk of Midlife Death

The findings suggest that young fathers have poorer health than men who become fathers at age 25 or older, but it's not clear why, the researchers said. Future research may tease apart the link between young fatherhood and how a man's family environment, early life circumstances and genetics may affect his risk of midlife death, the researchers wrote in the study, published online today (Aug. 3) in the Journal of Epidemiology & Community Health. It's possible that early fatherhood may interrupt career plans and push young dads into lower-paying jobs, which could impair their health, the researchers said.

Hot Finding: Spicy Food Linked with Longer Life

Firing up the flavors in your food may help you live longer: Eating spicy foods frequently may be tied to a slightly lower risk of an earlier death, according to a new study. In the study, researchers asked nearly 500,000 people in China how often they ate hot, spicy foods. The researchers found that the people in the study who ate spicy foods one or two days a week were 10 percent less likely to die during the study, compared with those who ate spicy foods less than once a week, according to the study published today (Aug. 4) in the journal The BMJ.

U.S. researchers show computers can be hijacked to send data as sound waves

By Joseph Menn LAS VEGAS (Reuters) - A team of security researchers has demonstrated the ability to hijack standard equipment inside computers, printers and millions of other devices in order to send information out of an office through sound waves. The new makeshift transmitting antenna, dubbed "Funtenna" by lead researcher Ang Cui of Red Balloon Security, adds another potential channel that likewise be would be hard to detect because no traffic logs would catch data leaving the premises. Hackers would need an antenna close to the targeted building to pick up the sound waves, Cui said, and they would need to find some way to get inside a targeted machine and convert the desired data to the format for transmission.

3 Years on Mars! Curiosity Rover Reaches Milestone

NASA's Mars rover Curiosity has now been trundling across the Red Planet for three very productive and eventful years. Curiosity landed on the night of Aug. 5, 2012, pulling off a dramatic and unprecedented touchdown with the aid of a rocket-powered "sky crane" that lowered the 1-ton rover gently to the Martian surface via cables. Curiosity quickly succeeded in this main task.

Malaysian Airlines Mystery: What Newfound Wing Debris Could Reveal

The high-profile disappearance of Malaysia Airlines Flight MH370 remains a mystery — but the recent discovery of a possible wing part points to an ocean landing, raising hopes for a resolution. There must be other pieces out there," said David Gallo, the director of special projects at the Woods Hole Oceanographic Institution in Massachusetts. The piece, possibly from the wing of the Malaysia Airlines plane that disappeared almost 500 days ago, made its way to the shores of RéunionIsland, a French island in the Indian Ocean that lies east of Madagascar.

Wild Beauty: Winning Ecology Photos Feature Sunbirds and Zebras

The winning photos from a recent ecology photo contest prove that Mother Nature is always ready for her close-up. Only researchers affiliated with a university or other research institution were eligible to submit photos, and the portraits had to fit into one of five categories related to ecology, or the study of how living things interact with one another and their environments. This year, the journal BMC Ecology invited a guest judge to select an overall winner for the contest.

New tidal energy system could help power UK, say developers

Harnessing tidal power around the UK's coast has so far been limited by the cost of the large dams and barrages required and unpredictable results. A British company, in conjunction with Oxford University researchers, believes it has devised a way to overcome this obstacle by creating a new type of horizontal axis turbine that can be used underwater at depths of up to 30 meters, at an economical cost. Conventional propeller-type turbines are like underwater wind turbines and the number of suitable sites for them are vastly reduced by the size of their large blades, limiting their use to waters at least 30 meters deep.

Superbug Forecast: Infections Will Increase in US

Infections caused by drug-resistant bacteria are projected to increase in the United States if no action is taken soon, but a national effort could prevent more than half a million infections in five years, a new study finds. In 2011, there were 310,000 cases of infection in the United States from four types of nasty bacteria that are usually acquired in hospitals: carbapenem-resistant Enterobacteriaceae (CRE), multidrug-resistant Pseudomonas aeruginosa, invasive methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile.

Extreme Stress May Convert Fat into Calorie Burning Machine

Severe stress may cause ordinary white fat cells to morph into energy-burning brown fat, new research suggests. "If you subject humans to very severe stress for a prolonged period of time, then even humans can turn their white fat into brown fat," said study co-author Labros Sidossis, a geriatric medicine researcher at the University of Texas Medical Branch in Galveston. The new findings are based on studies of victims with severe burns, and there is no evidence that the stress of work deadlines or even traumatic events would cause the same effect, the researchers said.

Monstrous Whirling Gas Cloud Reveals Clues About Galaxy Formation

For the first time, astronomers have spotted a protogalactic disk — a giant whirling cloud of gas that gives birth to a galaxy — and the discovery could reveal clues about how galaxies form. Galaxies are strung together in filaments separated by immense voids.
