Scientists' Quest: Making Chickens Happy

Study in Canada may result in better living conditions, even if only briefly

(Newser) - How do you measure a chicken's happiness? Is it in the way it runs for food? How much time it spends preening? To size up what might make chickens happy in their brief lives, researchers at the University of Guelph in Ontario, Canada, are putting 16 breeds through physical...

A Lego Needs 1.71 Days to Make the Unkindest Journey

If swallowed, that's how long it takes to reappear, researchers conclude

(Newser) - It may not be the most burning of unanswered science questions, but researchers have figured out how long it would take for a swallowed Lego to re-emerge in the toilet bowl. Figure 1.71 days. That was the average time for six brave volunteers who swallowed a Lego head, then...

Cambridge scientists reinforce old stereotypes; critics pounce on 'neurosexism'

(Newser) - In what's said to be the largest study examining differences between the sexes, a longtime stereotype is holding some water—though critics are pushing back on the supposed biological merit underlying the results. The Telegraph reports that researchers at the University of Cambridge tested more than 670,000 people...

Where Parkinson's May Start: the Appendix

But scientists say don't run out and get an appendectomy just yet

(Newser) - Scientists have found a new clue that Parkinson's disease may get its start not in the brain but in the gut—maybe in the appendix. People who had their appendix removed early in life had a lower risk of getting the tremor-inducing brain disease decades later, researchers report. Why?...

'Brain Training' App Shows Promise for OCD Sufferers

Subjects with strong contamination fears saw significant relief of symptoms after one week

(Newser) - There literally does appear to be an app for almost everything, and treating symptoms of obsessive-compulsive disorder just got its own entry. Treatment for OCD (a condition in which patients can't stop having obsessive thoughts and engaging in repetitive behaviors) has been notoriously hit or miss: UPI reports that...

Scientists Surprised at How Good Our 'Facial Vocabulary' Is

Researchers say human brain can hold an impressive number of faces

(Newser) - Humans have historically lived in groups of about 100, yet our facial recognition skills easily adapt to a modern world where we see endless faces each day, whether in person or on TV. A new study in Proceedings of the Royal Society B , the first to give an evidence-based estimate...

Pot's THC Levels: Relatively the Same, No Matter the Strain

Scientists: Levels of tetrahydrocannabinol and CBD don't vary much among different pot strains

(Newser) - For those who spend time at the dispensary agonizing over whether to go with the Acapulco Gold, Granddaddy Purple, or Chemdawg, know this: Their THC levels are likely pretty much the same, no matter which strain you pick, researchers out of UBC Okanagan say.

This Might Not Be a Great Idea for Women in Soccer

Study suggests female players suffer more brain damage than men after headers

(Newser) - A new study suggests that girls and women who play soccer should think twice about going up for that next header. Research out of the Albert Einstein College of Medicine found that females were five times more likely than men to suffer damage to the brain, reports Scientific American . The...

A Shift in Alzheimer's Strategy: Prevention

2 new studies aim to prevent early plaque formation

(Newser) - It may be too late to stop Alzheimer's in people who already have some mental decline. But what if a treatment could target the earliest brain changes while memory and thinking skills are still intact, in hope of preventing the disease? Two big studies are going to try, per...

Scientists Make 'Critical' Find on Honeybees, Herbicide

Glyphosate, used in Monsanto's Roundup, may kill off insects' essential gut bacteria

(Newser) - Animals don't seem to be harmed by the world's most widely used weedkiller, but bees apparently don't fall under that protective umbrella. "This is really critical," one entomologist tells Science of a new study showing the digestive system of honeybees (and possibly other bees as...

Prozac's Odd Side Effect: Less Frisky Birds

Females get trace amounts at sewage plants, become less desirable to mates

(Newser) - We humans consume a lot of antidepressants, and that means birds inadvertently do the same while feeding at sewage plants. Now researchers in the UK suggest that it's taking a toll on the birds' libidos, making them—or at least the females—less attractive to prospective mates. In their...

World's 'Most Widely Accepted Boundary' May Be Wrong

Astrophysicist says Karman Line is 50 miles above Earth, not 62

(Newser) - Astrophysicist Jonathan McDowell calls the Karman Line the world's "most widely accepted boundary." It's otherwise known as the point where space meets Earth's atmosphere, and since before the launch of Sputnik, it's thought to have hovered 62 miles above our heads. Until now. In...

NASA May Have Torched 'Building Blocks of Life' on Mars in 1976

New study suggests organic matter was discovered, but ruined by heat

(Newser) - Much was made of NASA's announcement last month that "building blocks of life" had been found on Mars. But new research suggests the same organic molecules may actually have been discovered by Viking landers NASA sent to Mars in 1976—and then accidentally burned, New Scientist reports. The...
