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?...

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...

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...

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

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...

World's Only 2 Northern White Rhinos May Not Be the Last

Scientists have created 'test tube rhino' embryos in hopes of saving the species

(Newser) - There are only two female northern white rhinos left in the world (the lone male, Sudan, died in March ), and they're infertile, but researchers are hoping new efforts on the reproduction front will stave off the end of the species. The world's first "test tube" rhinos...
