Conservationists working to preserve artifacts in the first buildings ever constructed in Antarctica have found something extraordinary: a perfectly preserved, 106-year-old fruitcake. No, the cake is not a sign that Santa Claus hails from the South ... Discuss
American doctors have been noticing an increase in osteoarthritis of the knee. They have suspected two driving forces: more old people and more people who are overweight. A study published in this week's Proceedings of the National Academy of Sciences ...
If you were going to cook up life on another world, Titan is the place to do it. Saturn's largest moon is rich with carbon, nitrogen and hydrogen — elements required by all living organisms on Earth. It has two types of wet ingredients — an ocean of ... Discuss
Well-trained guide dogs are important for visually impaired people who rely on them. But many puppies bred to be guide dogs flunk out of training programs. A study published Monday in the Proceedings of the National Academy of Sciences suggests the way a ... Discuss
A new device developed at The Ohio State University can start healing organs in a "fraction of a second," researchers say. The technology, known as Tissue Nanotransfection (TNT), has the potential to save the lives of car crash victims and even ... Discuss
When a thirty-year-old woman turned up to the Sir Charles Gairdner Hospital, in Western Australia complaining about an incredible amount of stomach pain, the cause of her suffering initially eluded the physicians trying to treat her. Blood tests that ... Discuss
Your Instagram feed may be better at recognizing signs of depression than your doctor, according to a study from researchers at Harvard University and the University of Vermont. Researchers used a machine learning computer program to analyze 43,950 ...
For the biggest animals, bulk is a great defense. Other creatures need tricks, like the snowy coat of an arctic hare or a hagfish's choking slime clouds. But elephants and rhinoceroses get by with tough hides and sheer size. They have little to fear ...
The first evidence for an exomoon — a moon orbiting a planet orbiting a distant star — may have been spotted in data from the Kepler space telescope. But surprisingly, exomoons in general may be rare, at least around planets close to their stars. Alex Teachey and ... Discuss
The Milky Way galaxy we call home is a pretty colossal place — up to 580 billion times more massive than the sun, according to one recent estimate.Just where did all this matter come from? Surprising new research suggests that half of it originated in distant ... Discuss
A defensive mucus secreted by slugs has inspired a new kind of adhesive that could transform medicine, say scientists. The "bio-glue" is incredibly strong, moves with the body and crucially, sticks to wet surfaces. The team at Harvard University have ... Discuss
In the far north of India, a cold mountain desert is the stunning backdrop to an unprecedented icy structure. This is a land of extremes, where rainfall is scarce and temperatures range wildly from torrid to far below freezing. The locals say it's the only ... Discuss
For decades, scientists have thought the moon was a dry, dusty place, but it may be time to re-write the astronomy books. New findings are upending decades of understanding about our closest neighbor in space; an analysis of satellite data suggests the ... Discuss
Three years ago, Christina D’Ambrosio went to her first spin class, pedaling fast on a stationary bike to the rhythms of popular music as an instructor shouted motivation. But Ms. D’Ambrosio, who exercises regularly, found the hourlong class was harder than she ...
Three new species of toads have been discovered living in Nevada's Great Basin in an expansive survey of the 190,000 square mile ancient lake bottom. Discoveries of new amphibians are extremely rare in the United States with only three new frog species ... Discuss
The signal was like nothing Abel Méndez had ever seen. It had the same frequency as radio emissions from satellites, but it pulsed like it came from something much more distant. It appeared only when Mendez and his colleagues had their telescope pointed ...
More than 1 in 3 cases of Alzheimer's disease and other forms of dementia can be traced to factors — such as inadequate education, obesity, hearing loss and smoking — that simply don't need to be, according to a new report. These challenges first ...
Last month, Popular Mechanics covered the exciting prospect of the first ever commercial moon landing, which could launch by December 2017 if everything goes according to plan. That mission involves Moon Express, a company that hopes to build a number of  ... Discuss
An image and short film has been encoded in DNA, using the units of inheritance as a medium for storing information. Using a genome editing tool known as Crispr, US scientists inserted a gif - five frames of a horse galloping - into the DNA of bacteria. Then ... Discuss
