Telomeres, tiny protective caps at the end of DNA, typically get shorter and shorter with age. But one creature — the edible dormouse — seems to have developed a way to reverse this process and forestall aging.

Do you know what's in your medical records?

Dec 19, 2016

In 1996, Congress enacted HIPAA (the Health Insurance Portability and Accountability Act), which was designed, in part, to give patients the right to access their own medical records. Twenty years later, much has improved, but patients still have trouble prying their personal information out of hospitals and health care systems. 

What are the best snow boots to wear?

Dec 17, 2016

Thousands of injuries and even some deaths occur when people slip and fall on winter ice. A new study has looked at the effectiveness of winter boot soles and found that very few of them measure up.

“Unfortunately, we tested over 100 boots, and only nine of them passed,” says Barry Westhead, director of research engineering at the Toronto Rehabilitation Institute.

That’s the bad news. The good news is that some new technologies are already on the market, and two of them perform particularly well, Westhead says.

Astronauts have countless official tasks to accomplish once they’re up and out of Earth’s atmosphere. But space walkers need hobbies, too.

New York City is home to one of the world’s most famous skylines. But for every landmark structure, there are dozens that never made it on the map. A floating airport on the Hudson River? Not quite. A gigantic dome protecting midtown Manhattan from bad weather? Never mind.

Think of Beatrix Potter, and what comes to mind? Flopsy, Mopsy, Cotton-tail and Peter Rabbit. Now, what about Crimson Waxcap?

That's the name of a mushroom. It might seem out of place, but fungi and other wonders of the natural world apparently held as much of a place in Potter's heart as the children's stories for which she's known today.

The notion initially surprised Linda Lear, one of the authors of the new book, "The Art of Beatrix Potter."

What's the role of social media in the news media?

In the days immediately following the US presidential election, a quick Google News search of the phrase “final election results” netted a slimy top result. It was an article claiming, incorrectly, that Donald Trump had won the popular vote.

Time travel, microbes, black holes, and polar bears. There’s something for everyone on this year’s list of best science books.

Maria Popova, founder of Brain Pickings, and Scientific American editor Lee Billings have combed the shelves and come up with this list of 18 books you might want to ask Santa to stick under your tree.

Horticulturist J.C. Raulston died in 1996, but his legacy lives on at the North Carolina State University arboretum that bears his name, the nine plants named in his honor, and all over the backyards and nurseries of North Carolina. 

It’s 2016. Why is the common cold still so hard to avoid?

Winter is setting in, marking the unofficial height of the dreaded “cold season” in offices and schools across the country.

The common cold is a familiar foe: Maybe you’re fighting one off right now, or stocking up on vitamin C, tissues and canned chicken soup for the long battle ahead. But despite the regularity of colds in daily life, there’s a lot you may not know about them. Where do they come from? Is there actually a link between colds and cold weather? And why don’t we have the ultimate weapon — a vaccine — to beat them once and for all?

A new report in Nature gives hopeful news about how we could recover from paralyzing spinal cord injuries in the future.

The moon just had its Hollywood close-up. In mid-November, its slightly elliptical orbit brought the full moon closer to Earth than it’s been since 1948, and it dazzled in the part. Photos from sky-gazers around the world show the familiar orb looking round, bright and startlingly big.

As it stands, the mushroom is already a multi-purpose organism: Aside from its ecological functions, it can be eaten as nourishment, brewed as tea, taken as a naturopathic remedy and used in dyes. But a San Francisco start-up by the name of MycoWorks has even more plans for mushrooms, starting with a leather-like material made from the fungi.

Conservationists want you to eat more of this fish. Wait, what?

With its arsenal of spiny, venom-tipped fin rays, the lionfish is not a typical (or easy) ingredient in your fish tacos. But at Norman’s Cay, a restaurant in downtown Manhattan, lionfish comes grilled or fried — and its mild white meat is starting to show up in other restaurants in Florida and New York.

If there’s one word that can sum up our feelings about this year’s presidential election — the most polarizing and bitterly fought in recent memory — it might just be “stressful.”

In October, a survey by the American Psychological Association found that the election was a significant source of stress for more than half of all Americans. And now that Election Day has passed, we’re probably still reeling — whether from a hard-fought battle or our candidate’s loss at the polls.
