Why Does the Moon Turn Red During a Total Lunar Eclipse?

Tonight, an oversized ruby-colored sphere will rise in the sky as a total lunar eclipse turns the normally pallid moon scarlet. The so-called supermoon is also at the perfect spot in its orbit so the alignment between the sun, Earth and moon will be perfect … for a total lunar eclipse: At about 8:11 p.m. EDT (0011 GMT), the moon will tiptoe into the outer portion of Earth's shadow, becoming totally bathed in the darkest part of that shadow at 10:47 p.m. EDT (0247 GMT), with the total lunar eclipse ending at about 1:22 a.m. EDT (0522 GMT). When the Earth is directly in front of the sun — blocking the sun's rays from lighting up the moon — you'd see a fiery rim encircling the planet.

Apple Watch Credited with Saving Life: What Conditions Can It Detect?

A Massachusetts teen says the Apple Watch saved his life, by alerting him that his heart rate was much higher than normal, leading to a diagnosis of a life-threatening condition. Experts say the gadget — and similar devices — could potentially detect alterations in people's heart rates that might be a sign of health problems. Paul Houle Jr., a high school senior, said he felt back pain after two football practices on the same day, but he didn't think much of it, according to Huffington Post.

I'm all ears: fossils reveal human ancestors' hearing abilities

By Will Dunham WASHINGTON (Reuters) - Two-million-year-old fossils including the three tiny bones of the middle ear are helping scientists figure out the auditory abilities of early human ancestors at a time when they were beginning to hear more like a person and less like a chimpanzee. A study published on Friday involving two species from South Africa, Australopithecus africanus and Paranthropus robustus, showed they boasted better hearing than either chimps or people in a frequency range that may have facilitated vocal communication in a savanna habitat. Both species featured a mixture of ape-like and human-like anatomical traits and inhabited grassland ecosystems with widely spaced trees and shrubs, as opposed to the forests of earlier members of human lineage.

U.S. culls over 1,200 Oregon cormorants, sparks outcry

By Shelby Sebens PORTLAND, Ore. (Reuters) - The U.S. federal government has killed more than 1,000 seabirds on an Oregon island since May to protect endangered salmon as part of a plan that environmentalists say is flawed and are seeking to stop with a lawsuit. "Government agents are racing about in their boat blowing birds out of the sky," said Bob Sallinger, conservation director of the Audubon Society of Portland. "The public has a right to see how the federal government is squandering millions of taxpayer dollars killing protected wild birds." The government workers started culling the birds on May 24 as part of a multi-year plan to kill 11,000 double-crested cormorants, which U.S. wildlife officials say are putting endangered salmon at risk by eating juvenile fish.

Tanzanian engineer invents low-cost water filter

(Reuters) - It looks good enough to drink but just seconds before, this water was full of dirt and bacteria.     Dr. Askwar Hilonga is a Tanzanian scientist who has created a water filter that he says can remove 99.9 percent of bacteria, micro-organisms and viruses.     The invention uses nanotechnology to filter out contaminants and produce clean water.     The idea was inspired by a visit to his parents' village outside Arusha in Tanzania, where many people still risk their lives drinking dirty water and often suffer from water-borne diseases.     Catherine Nanyaro is a housewife and lives in Arusha.

Water Woes: Firefighters Get Creative to Douse Flames in California

California's drought could make fighting wildfires even harder, experts say. California is facing one of its worst fire seasons on record, with nearly three-dozen wildfires blazing across the Golden State, according to the National Wildfire Coordinating Group. But the drought has also dried up water sources needed to help douse the flames, said Carroll Wills, the communications director for the California Professional Firefighters Association.

Unusual Allergy: Girl Reacts to Food Only After Exercise

A teenage girl in Canada had an unusual food allergy that showed up only after she exercised, according to a new report of her case. The 17-year-old's allergy first appeared when she had a small snack — a few rice crackers and hummus — right before she worked out on a treadmill at her home. "We hope that this case will serve as an important reminder that although rare, food-dependent exercise-induced anaphylaxis exists and making a diagnosis can lead to life-saving preventative strategies," the researchers at Montreal Children's Hospital, who worked on the girl's case, wrote in their report, published online Sept. 3 in the Journal of Medical Case Reports.

God Help Us? How Religion is Good (And Bad) For Mental Health

This week millions of Americans are navigating crushing crowds and spending hours traveling in order to catch a glimpse of Pope Francis on his first visit to this country. To those who are devoutly religious, the pope's U.S. trip presents a unique opportunity to get papal blessings, receive mercy and feel closer to God. But even those devoted Catholics who aren't in the front row seat for Francis' visit may see benefits to their belief. A slew of research has tied being religious with better well-being and overall mental health. A number of studies have found that devout people have fewer symptoms of depression and anxiety, as well as a better ability to cope with stress.

Salty Water Flows on Mars Today, Boosting Odds for Life

Liquid water flows on Mars today, boosting the odds that life could exist on the Red Planet, a new study suggests. The enigmatic dark streaks on Mars — called recurring slope lineae (RSL) — that appear seasonally on steep, relatively warm Martian slopes are likely caused by salty liquid water, researchers said. "Liquid water is a key requirement for life on Earth," study lead author Lujendra Ojha, of the Georgia Institute of Technology in Atlanta, told Space.com via email.

Belgian scientists look for biofuel clues in panda poo

By Robert-Jan Bartunek BRUGELETTE, Belgium (Reuters) - Belgian researchers are examining the excrement of giant pandas to try to understand how they can digest tough bamboo, hoping for clues on how to develop new generations of biofuel. The genetic make-up of endangered pandas is that of a carnivore but the animals have adapted to a diet consisting almost exclusively of bamboo. "We can look for new enzymes which could be used to degrade tough biomass," said Korneel Rabaey, professor for biochemical and microbial technology at Ghent University, standing outside the giant panda enclosure at the Pairi Daiza zoo in Belgium.

Ringing Ears and Chronic Pain Share Unexpected Link

In the review, the authors proposed that tinnitus, or ringing in the ears, and chronic pain are the result of similar changes in two regions of the brain. These regions — the nucleus accumbens and the ventromedial prefrontal cortex — are both in the front of the brain, and may act as "gatekeepers" for sensory stimuli such as noise and pain, the researchers said. "It's a very clever system," said Josef Rauschecker, a professor of physiology and biophysics at Georgetown University and lead author of the review, published today (Sept. 23) in the journal Trends in Cognitive Sciences.
