Cold Comfort: Why Office Air Conditioning Is Biased Against Women

Office building managers who set air conditioners to frigid temperatures are not only sending shivers up the spines of workers, they're also wasting money and energy, a new study finds. Air-conditioning and heating standards in office environments were originally set based on the resting metabolic rates — a measure of how much energy a person uses at rest — for males, the researchers said. In fact, the standards were developed in the 1960s to accommodate the resting metabolic rate of a 40-year-old man who weighs 154 lbs. (70 kilograms), they said.

U.S. drones capture breath samples from humpback whales in study

BOSTON (Reuters) - Researchers at the Woods Hole Oceanographic Institute in Cape Cod have begun using a helicopter-style drone to monitor humpback whales off the coast, collecting breath samples from their blowholes and taking aerial pictures. The scientists first deployed the 32-inch "hexacopter" drone in July to help assess the health of whales living in the Stellwagen Bank National Marine Sanctuary, about 45 miles (72 km) east of Boston, where there is significant ship traffic and pollution, Woods Hole said in a release on Monday. ...

Measles Vaccine: Images of Sick Kids May Convince Skeptics

The best ways to convince people of the benefits of vaccinations may be to show them pictures of a child with measles or to have them read a description of the disease written by a mom whose child was infected, according to a new study. These ways are more effective than showing people information summarizing recent research that shows there is no link between vaccines and an increased risk of autism in children, the researchers found. The researchers found that directing people's attention to the risks posed by not getting vaccinated by showing them the pictures of sick children and having them read a mom's written account of her child's disease changed their attitudes, leading them to think more positively about vaccinations, study author Zachary Horne, a graduate student at the University of Illinois, said in a statement.

Picky Eating in Kids Tied to Anxiety, Depression

Almost everyone knows a 4-year-old who's never eaten an apple, subsists off hot dogs and spaghetti or eats only white food. But a new study suggests that such picky eating isn't the norm, and that it may even hint at future mental health issues, in some cases. Children who are selective eaters are likelier to develop anxiety, depression and attention deficit hyperactivity disorder (ADHD), according to the study, published today (Aug. 3) in the journal Pediatrics.

Vader Crater, Kirk & Spock! 'Star Wars,' 'Star Trek' Collide on Pluto Moon

The "Star Trek" and "Star Wars" universes are coming together on Pluto's big moon Charon. The team behind NASA's New Horizons spacecraft, which performed the first-ever Pluto flyby last month, has unofficially named some Charon craters after characters from both beloved sci-fi franchises. For example, newly released maps created by the New Horizons crew reveal that Charon now has a Vader Crater, as well as impact features named after fellow "Star Wars" principals Luke Skywalker and Princess Leia.

3D Supernova Simulation Turns Back Clock on Star Explosions

Enormous stars collapse in ultramassive supernova explosions — now in 3D! For the first time ever, researchers have turned back the clock on a star's final moments to simulate how wrinkles in its violent collapse trigger a vast explosion. "Almost all supernova simulations follow about 1 second of physical time," said Sean Couch, a physicist and astronomer at Michigan State University and lead author of the new paper. Such a feat was very technologically demanding, but it proved necessary because models starting right at the collapse just wouldn't explode in a supernova, Couch said.

Can Young Blood Improve Old Brains?

The blood of young people may hold compounds that benefit the brains of older people with Alzheimer's disease, so scientists are now looking at whether transfusions may help people with the condition. Research in animals has shown that the blood of the young may counter some of the effects of aging in older brains. For instance, it might help to improve learning and memory, as well as generate new brain cells.

Soda Fizzles: US Appetite for Sugary Drinks Wanes

America's seemingly bottomless thirst for soda may be waning, according to a new Gallup poll. Diet and regular soda are at the top of the list of things that people said they try to avoid in their diets, with 62 percent saying they avoid drinking diet soda, and 61 percent saying they avoid regular soda, according to Gallup.

Goliath Gates: Entrance to Famous Biblical Metropolis Uncovered

A massive gate unearthed in Israel may have marked the entrance to a biblical city that, at its heyday, was the biggest metropolis in the region. The town, called Gath, was occupied until the ninth century B.C. In biblical accounts, the Philistines — the mortal enemies of the Israelites — ruled the city. The new findings reveal just how impressive the ancient Philistine city once was, said lead archaeologist of the current excavation, Aren Maeir, of Bar-Ilan University in Israel.

Apollo Moon Rocket Engines Recovered by Amazon CEO Preserved for Display

Two and a half years after an expedition led by the CEO of Amazon.com raised them off the ocean floor, the historic rocket engine parts that launched NASA astronauts on at least three missions to the moon are now preserved for museum display. The conservation team at the Cosmosphere International SciEd Center and Space Museum (formerly known as the Kansas Cosmosphere and Space Center) in Hutchinson, Kansas completed researching and stabilizing the 25,000 pounds (11,340 kg) of Saturn V F-1 engine parts in June. The mangled and twisted Apollo artifacts were recovered by a privately-financed effort organized by Amazon.com's Jeff Bezos more than four decades after the engines were used in the launches of the first, second and fifth manned moon landings.

Eco-friendly 3D printed supercar

By Ben Gruber A California automotive start-up is hoping their prototype supercar will redefine car manufacturing. The sleek race car dubbed 'Blade' didn't come off an assembly line - but out of a 3D printer. Kevin Czinger of Divergent Microfactories has spent most of his career in the automotive industry.
