When you first meet Moises Velasquez-Manoff, the first thing you notice is his hair — or the lack of it.

He's completely bald.

"At age 11, I developed this condition, called alopecia areata, where I lost my hair," says Velasquez-Manoff, a science writer in Berkeley, Calif. "It started in patches, but eventually I lost it all."

Sharks can live to be at least 272 years old in the Arctic seas, and scientists say one recently caught shark may have lived as long as 512 years.

How Worm Warriors Are Beating An Unbeatable Worm

Aug 11, 2016

How do you get rid of river blindness? It's all about the worm.

Specifically, about "breaking the life cycle" of onchocerca volvulu, the parasitic worm that causes the disease, says Dr. Frank O. Richards Jr., who directs the Carter Center's river blindness elimination and other tropical disease programs.

Researchers in Brazil who are trying to help people with spine injuries gain mobility have made a surprising discovery: Injured people doing brain training while interacting with robot-like machines were able to regain some sensation and movement.

Oil that spilled from a derailed train in the Columbia River Gorge in June contaminated nearby groundwater. Starting in the next week, Union Pacific Railroad will be working with Oregon’s Department of Environmental Quality to clean it up.

Night owls and stargazers, get ready for something spectacular on Thursday.

The annual Perseid meteor shower, already one of the most reliably impressive celestial events, promises to be especially good this year.

The Perseid shower happens every year in August "when Earth ventures through trails of debris left behind by an ancient comet," according to NASA.

Three college-age scientists think they know how to solve a huge problem facing medicine. They think they've found a way to overcome antibiotic resistance.

Many of the most powerful antibiotics have lost their efficacy against dangerous bacteria, so finding new antibiotics is a priority.

It's too soon to say for sure if the young researchers are right, but if gumption and enthusiasm count for anything, they stand a fighting chance.

"Microbes have always ruled the planet but for the first time in history, they are fashionable," writes Ed Yong in his new book, I Contain Multitudes: The Microbes Within Us and a Grander View of Life, on sale Tuesday.

Athletes Go For Gold With Red Spots Blazing

Aug 8, 2016

Swimmer Michael Phelps won Olympic gold again Sunday while covered in red — red spots, roughly medal-size, all over his shoulders and back.

The marks were the result of an ancient Eastern medicinal therapy known as cupping that is achieving new popularity among some athletes in the United States, including numerous Olympians.

Cupping typically involves treating muscle pain and other ailments with cups that apply suction to skin. Cupping is often combined with other forms of alternative medicine, such as acupuncture and massage.

This summer, NPR's science desk is thinking about waves, of all kinds — ocean, gravitational, even stadium waves. But what is a wave, anyway? My editor asked me to puzzle that one out. And, to be honest, I was puzzled.

Is a wave a thing? Or is it the description of a thing? Or is it a mathematical formula that produces a curve that gives you the description of a thing?

It's dusk at a park in Dallas, and white sheets are pinned up next to tall trees, fluttering like ghosts in the wind. They've been lit up with ultraviolet lights to attract moths.

A handful of people are holding up their smartphones, zooming in on the small dark specks that fly to the cloth.

"Bugs have become my obsession," says Annika Lindqvist. "And the more you look, the more you have to look at the tiny things, and when you blow them up you see that they are gorgeous."

Many medical studies involving children never end up being put to use because scientists frequently don't publish the results of their work, according to an analysis published online Thursday.

The findings raise both scientific and ethical issues regarding research on this vulnerable population.

The federal government announced plans Thursday to lift a moratorium on funding of certain controversial experiments that use human stem cells to create animal embryos that are partly human.

The National Institutes of Health is proposing a new policy to permit scientists to get federal money to make embryos, known as chimeras, under certain carefully monitored conditions.

Copycat versions of biotech drugs work just as well as the originals and cost a lot less, according to an analysis of studies of the medicines.

The analysis by researchers at Johns Hopkins Bloomberg School of Public Health finds that so-called biosimilars — medications that are meant to mimic, and compete with, complex and expensive biotech drugs — perform as well as the brand-name versions.

Mix swimming and basketball with soccer, toss in some wrestling for good measure, and you have a pretty good description of the exciting, fast-paced sport of water polo.

The U.S. women's water polo team is ranked No. 1 in the world and is considered the favorite to bring home the gold medal at the Rio Olympics.

Since women's water polo became an Olympic sport in 2000, the U.S. women have medaled every time, and they won their first gold in London four years ago.

Adam Summers used to trade Snickers bars to get free CT scans of dead fish.

He likes fish. A lot.

Summers is a professor at the University of Washington in the biology department and School of Aquatic and Fisheries Sciences.

"I've always been a fish guy," he says. "It's just been in my blood since I was as small as I can remember." Summers was a scientific consultant on Finding Nemo and did similar work with Finding Dory.

Can Diabetes Alert Dogs Help Sniff Out Low Blood Sugar?

Jul 29, 2016

For people with diabetes who take insulin, the risk of losing consciousness from low blood sugar is a constant fear. Devices called continuous glucose monitors (CGMs) can alert wearers to dropping levels, but not everyone has access to them. And even among those who do, some prefer a furrier and friendlier alert option: a service dog with special training to alert owners when their blood sugar reaches dangerously low levels.

Researchers have found a curious purple orb near California's Channel Islands – and it's left them stumped.

A group of nano-scientists has discovered a way to arrange individual atoms to store and rewrite data 500 times more efficiently than the best hard drives on the market.

The 2,200-year-old mummy of an Egyptian man who spent a lot of time sitting and eating carbs went on display at the Israel Museum in Jerusalem on Tuesday and will be open to the public beginning Wednesday.

What does it mean to age? When are we over the hill? And what are the side effects of a longer lifespan?

On our most recent episode of Sound Effect on KPLU, we explored the idea of aging with Dr. Dan Gottschling. 

An African bird called the Greater honeyguide is famous for leading people to honey, and a new study shows that the birds listen for certain human calls to figure out who wants to play follow-the-leader.

The finding underscores the unique relationship that exists between humans and this wild bird.

In the summertime, the air is thick with the low humming of bees delivering pollen from one flower to the next. If you listen closely, a louder buzz may catch your ear.

When Sarah Gardner was 34, she started getting worried about whether she'd ever have a baby. So she took a test that aims to measure a woman's fertility.

The results terrified her. They indicated she had the fertility of a woman a decade older — a woman in her mid-40s.

"I was devastated," Gardner says. The news hit her especially hard because she was in the midst of breaking up with her longtime boyfriend.

Summer vacations: We wait for them all year. We pour time, energy and money into planning them. Expectations can run unreasonably high.

A Chemist Accidentally Creates A New Blue. Then What?

Jul 17, 2016

Mas Subramanian wasn't expecting blue.

In 2009, as part of his lab at Oregon State University, Subramanian — a professor of materials science — was working with students to manufacture new materials that could be used in electronics. They would mix and grind chemicals, then heat them to over 2000 degrees Fahrenheit.

One grad student, Andrew E. Smith, took a particular mix out of the furnace to find it had turned a surprising, bright blue color.

"You know what Louis Pasteur said?" Subramanian asks. "Luck favors the alert mind."

The way clouds cover the Earth may be changing because of global warming, according to a study published Monday that used satellite data to track cloud patterns across about two decades, starting in the 1980s.

Clouds in the mid-latitudes shifted toward the poles during that period, as the subtropical dry zones expanded and the highest cloud-tops got higher.

When a goat gazes into your eyes, it may be issuing a silent plea for help.

That's the suggestion from a new study of goats co-authored by Christian Nawroth, who researches animal cognition at Queen Mary University of London, published in Biology Letters.

Scientists have created a synthetic stingray that's propelled by living muscle cells and controlled by light, a team reports Thursday in the journal Science.

And it should be possible to build an artificial heart using some of the same techniques, the researchers say.
