Scientists Are Vacuuming DNA Out of Thin Air

Researcher envisions worldwide monitoring system for wildlife using environmental DNA

(Newser) - More than a decade ago, research began to describe the detection of DNA released by organisms into their environments. For the last several years, this environmental DNA has allowed scientists, including those at the US Geological Survey , to get a handle on the distribution and abundance of small, rare, or...

3 Cheetahs, 2 Cubs, One 'Big Breakthrough'

Birth via surrogacy allows for greater genetic diversity

(Newser) - Ohio has welcomed two new scientific marvels—the first ever cheetah cubs born via in vitro fertilization. Cheetahs are a vulnerable species, with only 7,500 left in the wild. They also have low genetic diversity owing to a mass die-off about 10,000 years ago. That's made breeding...

The Biggest Physics Breakthroughs of the Year

We now know what's needed for secure quantum teleportation

(Newser) - Physics World has given its 2015 Breakthrough of the Year award to two scientists in China who demonstrated the requirements for secure quantum teleportation. Sadly, this doesn't mean you'll be able to randomly appear anywhere in the world, but it's pretty cool regardless. Basically, the research...

Schizophrenia Isn't Actually One Disease

Genetic research points to 8 disorders

(Newser) - Genetic research is paving the way to a "new era" in psychiatry, a researcher says, and that includes a different way of looking at schizophrenia: It's not one disease, but rather eight different ones, divided by their genetic profiles, a study suggests. Researchers reviewed genetic data from 4,...

This Tiny Copper Awl Is Rewriting History

Awl is oldest metal object ever found in Middle East

(Newser) - A small copper awl found in a woman's ancient grave in Israel is rewriting history. It's the oldest metal object ever found in the Middle East, and was probably owned by the apparently important 40-year-old woman buried with it in an extravagant Tel Tsaf grave, LiveScience reports. The...

Scientists Peak in Their Late 30s

Education may explain phenomenon

(Newser) - Good news for struggling scientists in their mid-30s: Your big breakthrough is probably still to come. So says a new study from the National Bureau of Economics Research, which finds that great scientists and inventors see their biggest moments of genius in their late 30s, the Atlantic reports. Education may...

'Brain Dead' Might Not Mean Brain Dead After All

Study detects activity even after a flat EEG line

(Newser) - An intriguing new study out of Montreal might redefine our concept of being "brain dead." Researchers for the first time think that the brain remains active even in patients whose EEG lines have gone flat, reports the Los Angeles Times . The study sprang from an unusual case in...

Study: Teeth Can Be Made From Urine

Chinese scientists managed to grow teeth-like structures

(Newser) - It's a scientific feat equal parts fascinating and stomach-turning: Scientists have been able to grow "rudimentary teeth" from urine, reports the BBC . Suspend your disbelief, and read on: The Chinese team's process, as outlined in Cell Regeneration Journal, had researchers harvest cells from urine and then convert...

Culprit in Irish Potato Famine Finally Discovered

Potato blight strain HERB-1 now apparently extinct

(Newser) - Nearly two centuries later, researchers believe they have identified the pathogen that led to Ireland's deadly potato famine. To make their discovery, British, German, and American scientists sequenced DNA from samples of dried potato leaves collected between 120 and 170 years ago, reports PhysOrg. They identified the particular strain...

Scientists Create New Ear —With 3D Printer

Project uses living cells

(Newser) - Scientists at Cornell have put 3D printing to an incredible medical use: They've made an ear remarkably similar to a natural one. Using 3D images of a human ear, they printed a mold to be injected with gel containing collagen from rats' tails, HealthDay reports. Next, they added cartilage...

What Scares Even the Medically Fearless

Suffocation ignites different form of fear: study

(Newser) - A much-studied woman was thought to be fearless—literally unable to experience the emotion after having part of her brain, the amygdala , damaged. Nothing from snakes to assaults could scare the woman, dubbed SM, until, in a recent study, she was faced with the feeling of suffocation. That prompted a...

Scientists Decode Banana Genome

Breakthrough could help keep millions fed in developing nations

(Newser) - They got the tomato in May, and now researchers have sequenced the banana genome, too. It's no mere scientific exercise—the feat could have huge implications in the developing world, explains the Los Angeles Times . Bananas are a vital source of food for hundreds of millions, but they're...
