A group of scientists is gathering this week in the U.K. to discuss a slab of ice that's cracking in Antarctica. The crack could soon split off a frozen chunk the size of Delaware.

One glacier scientist, Heidi Sevestre, spent six weeks last year living on that giant slab of ice off the Antarctic Peninsula.

When Samantha Deffler was young, her mother would often call her by her siblings' names — even the dog's name. "Rebecca, Jesse, Molly, Tucker, Samantha," she says.

For years, women have been told that regular mammograms can help reduce their risk of dying from breast cancer by catching tumors at their earliest, most treatable stages.

But a Danish study is the latest research to challenge that assumption. Researchers followed thousands of women in Denmark over more than a decade and found that perhaps one-third of the abnormalities detected by mammograms may never cause health problems.

They Never Told Her That Girls Could Become Scientists

By many standards, Mireille Kamariza is at the top of the world.

She's a graduate student at one of the world's top universities, working on her Ph.D. with one of the world's top chemists. And she's tackling a tough problem — tuberculosis — that sickens nearly 10 million people a year.

A Canadian doctor who is opposed to a widely used drug for morning sickness has fired another volley.

Writing in the journal PLOS ONE, Dr. Navindra Persaud in the department of family and community medicine at St. Michael's Hospital in Toronto, notes that an unpublished study that supported use of the drug, conducted in the 1970s, is seriously flawed.

The flu is making rounds, and health officials across Washington say that 2017 is shaping up to be a severe season. 

“It’s never too late to get the flu shot," said Edie Jeffers, spokeswoman for the Tacoma-Pierce County Health Department.

Each year, the flu vaccine is reformulated to match the latest strain of influenza.

People think of black holes as nightmare vacuum cleaners, sucking in everything in reach, from light to stars to Matthew McConaughey in the movie Interstellar. But, in real life, black holes don't consume everything that they draw in.

The 24 juniors and seniors in the astronomy class at Thomas Jefferson High School in Alexandria, Va., sink into plush red theater seats. They're in a big half-circle around what looks like a giant telescope with a globe on the end. Their teacher, Lee Ann Hennig, stands at a wooden control panel that has enough buttons and dials to launch a rocket.

Terrorist attacks, hurricanes, a divisive U.S. election, Brexit — 2016 has not been easy. With the year coming to an end, we thought it was time to get some serious perspective — from the scale of the entire universe.

We're tackling big questions: what scientists know, and what they have yet to learn.

So before you ring in another year, take a moment to contemplate the billions of years that led to 2017 and the billions more yet to come.

On the top of Hawaii's Mauna Kea mountain Thursday, astronomers will point the large Subaru Telescope toward a patch of sky near the constellation of Orion, looking for an extremely faint object moving slowly through space.

If they find what they're looking for, it will be one of the most important astronomical discoveries in more than a century: a new planet in our solar system.

Vera Rubin, the groundbreaking astrophysicist who discovered evidence of dark matter, died Sunday night at the age of 88, the Carnegie Institution confirms.

Rubin did much of her revelatory work at Carnegie. The organization's president calls her a "national treasure."

In the 1960s and 1970s, Rubin was working with astronomer Kent Ford, studying the behavior of spiral galaxies, when they discovered something entirely unexpected — the stars at the outside of the galaxy were moving as fast as the ones in the middle, which didn't fit with Newtonian gravitational theory.

It's a time of year when we're often urged to be grateful; for friends, for family, for presents under the tree. But not everyone experiences gratitude as a positive force in their life.

This winter brings the latest installment of the Star Wars franchise, full of familiar costumes, familiar villains, and the familiar "pew pew pew" of space guns. But you can skip the movie theatre and still hear those iconic blaster sounds if you visit a frozen lake.

Could vaccinating cattle get more girls into high school?

That's the intriguing prospect suggested by a new study of Kenyan cattle herding families in the journal Science Advances. But even more significant than the actual results of the study is the fact the researchers would even think to investigate whether there's a link between cattle vaccination rates and girls' high school attendance.

Scientists in Ireland are using a rather unexpected material to make an extremely sensitive pressure detector: Silly Putty.

The Irish researchers combined the kids' plaything with a special form of carbon, and came up with a remarkable new material — one they think could someday be useful in making medical devices.

In 2015, Lida Xing was visiting a market in northern Myanmar when a salesman brought out a piece of amber about the size of a pink rubber eraser. Inside, he could see a couple of ancient ants and a fuzzy brown tuft that the salesman said was a plant.

As soon as Xing saw it, he knew it wasn't a plant. It was the delicate, feathered tail of a tiny dinosaur.

The high-stakes fight over who invented a technology that could revolutionize medicine and agriculture heads to a courtroom Tuesday.

A gene-editing technology called CRISPR-cas9 could be worth billions of dollars. But it's not clear who owns the idea.

U.S. patent judges will hear oral arguments to help untangle this issue, which has far more at stake than your garden-variety patent dispute.

A single tornado can cause a lot of damage. But even worse are tornado outbreaks. Just this week, a cluster of at least 18 tornadoes struck the Southeast over two days.

Scientists are seeing bigger clusters in recent years, and they're struggling to figure out what's happening.

Forget where you just left your car keys? A magnetic pulse might help you remember.

Some dormant memories can be revived by delivering a pulse of magnetic energy to the right brain cells, researchers report Thursday in the journal Science.

The finding is part of a study that suggests the brain's "working memory" system is far less volatile than scientists once thought.

A nonprofit research group is giving scientists a new way to study the secret lives of human cells.

On Wednesday, the Allen Institute for Cell Science provided access to a collection of living stem cells that have been genetically altered to make internal structures like the nucleus and mitochondria glow.

Part of our ongoing series exploring how the U.S. can educate the nearly 5 million students who are learning English.

Brains, brains, brains. One thing we've learned at NPR Ed is that people are fascinated by brain research. And yet it can be hard to point to places where our education system is really making use of the latest neuroscience findings.

Getting the flu while pregnant doesn't appear to increase the child's risk of being diagnosed with autism later on, a study finds, and neither does getting a flu shot while pregnant.

NASA is looking for some help making the solar system's most portable port-a-potty.

So if you think you know the best way to poop in a spacesuit, the agency is ready to hear it ... and you might make $30,000 for your trouble.

You may think of ants as picnic pilferers. After all, who hasn't had to ward off ants stealing crumbs from picnic tables or hoarding tiny pieces of food from kitchens? But a new study shows that they're in fact hard working farmers. Or at least one species of ants is. It lives in Fiji and has been farming plants for some 3 million years.

Halloween has come and gone, but piles of candy remain. You have two options: Eat it all and risk a serious sugar coma, or get seriously creative with some candy-themed science.

We asked employees at various science museums what experiments they like to do with leftover candy. Get crackin'.

Halloween plays on our fears and our fantasies.

We craft haunted houses and scary decorations to evoke particular emotions. We choose our costumes to reflect something about the kinds of people we are or want to be — edgy, sexy, funny, clever. For children, Halloween is an experiment in delayed gratification and negotiation — which candies to eat now, which to trade, which to save. It's no surprise, then, that Halloween might reveal interesting features of human psychology.

But you might be surprised by just what we can learn.

Researchers have launched an innovative medical experiment that's designed to provide quick answers while meeting the needs of patients, rather than drug companies.

Traditional studies can cost hundreds of millions of dollars, and can take many years. But patients with amyotrophic lateral sclerosis, or Lou Gehrig's disease don't have the time to wait. This progressive muscle-wasting disease is usually fatal within a few years.

Antarctica's ice has been melting, most likely because of a warming climate. Now, newly published research shows the rate of melting appears to be accelerating.

Antarctica is bigger than the U.S. and Mexico combined, and it's covered in deep ice — more than a mile deep in some places. Most of the ice sits on bedrock, but it slowly flows off the continent's edges. Along the western edge, giant glaciers creep down toward the sea. Where they meet the ocean, they form ice shelves.

The Amorphophallus titanum is a striking plant even before you get close enough to smell it. Its scientific name means giant, misshapen phallus and it is not hard to see why. A giant column called a spadix rises 7 feet into the air from the center of a pleated funnel.

New research finds little lies pave the way for big ones.
