Fossil Find Shakes Up Evolution Timeline

Ardipithecus ramidus lived in trees and walked upright

(Newser) - A primate fossil found in Africa in 1994 predates the famous “Lucy” skeleton by 1 million years and offers clues to human evolution, researchers say. “This is huge,” a paleoanthropologist tells the Washington Post. “This is the biggest discovery really since” Lucy.

Women More Selective Daters? Maybe Not

(Newser) - Women may be more “selective” daters, but that distinction could well be based not on innate personality but on social norms and the simple prospect of which gender is doing the pursuing. A new study had subjects participate in a few rounds of speed dating. When the males approached...

How Thin People Make Other People Fat

New study shows we mimic habits of those whose bodies we aspire to

(Newser) - Existing research suggests those trying to control their food intake should avoid dining with hefty companions with heaping plates. Not quite, says a new study.

Offspring of hands-off parents test better: scientists

Being overweight or obese accounts for up to 8% of cancers in Europe. That figure is poised to increase substantially as the obesity epidemic continues, and as major causes...

Lather, Rinse, Disinfect the Showerhead

But even bleach may not kill stealth bacteria invading your bathtub

(Newser) - The showerheads of America are crawling with bacteria that can cause pulmonary disease in people with weakened immune systems, LiveScience reports. Around 20% of showerheads tested for a new study held significant levels of Mycobacterium avium, which can be suspended in air when water flows and be inhaled deep into...

Nighttime Snacks Worse Than We Thought

Mouse study shows weight gain more than doubles on opposite schedule

(Newser) - Eating when you should be sleeping—the proverbial midnight snack, say, or the meals of night-shift workers—could put you at higher risk of obesity, Time reports. A new study fed two groups of mice the same high-fat diet on opposite schedules; the group that ate during “normal” waking...

Temps, up 2.2 F Since 1900, Would Be 2.5 Degrees Cooler Without Greenhouse Gases

(Newser) - Summer temperatures in the Arctic have climbed 2.2°F since 1900 despite an 8,000-year cooling trend, the Guardian reports. For the past few thousand years, the orbit of the Earth and the changing tilt of its axis has put the Arctic 630,000 miles further from the sun...

Shrinking brains are tied to dementia, so the discovery fuels the notion that obesity can raise the risk of the cognitive disorder, New Scientist reports. In a review of 94 brain scans, subjects with...

New Heroin Addiction Treatment? Heroin

Scientists caution that controversial treatment has its downsides

(Newser) - Medical heroin may be effectively used to treat heroin addiction, Canadian scientists have discovered, but their dramatic findings may be railroaded over political and financial concerns, ABC News reports. Injectable diacetylmorphine, the active ingredient in heroin, resulted in 67% less illegal activity and illicit drug use after one year when...

Hold Music Improves, But Slowly

(Newser) - We may have Erik Satie to blame for hold music—the composer “developed a very cynical attitude” toward a distracted listening public and decided modern music would be more like a chair than an intellectual pursuit—but the science behind it is state-of-the-art, Newsweek reports. Studies on the intrusion...

55% of women carry variant placing them at a higher risk

(Newser) - An international coalition of geneticists has discovered a DNA variant in women with ovarian cancer that could lead to earlier detection and lower mortality rates, reports the Guardian.
