Far from our galaxy, in the vast darkness of space, two massive black holes merged into a single, larger hole.

And now researchers say they have detected rumblings from that cataclysmic collision as ripples in the very fabric of space-time itself. The discovery comes a century after Albert Einstein first predicted such ripples should exist.

Bill Radke talks to Onnie Rogers, research assistant professor at the University of Washington's Institute for Learning and Brain Sciences about her work on how stereotypes affect young black men. 

There's been a male tilt to biomedical research for a long time.

The National Institutes of Health is trying to change that and is looking to bring gender balance all the way down to the earliest stages of research. As a condition of NIH funding, researchers will now have to include female and male animals in their biomedical studies.

As late as the 1990s, researchers worried that testing drugs in women who could be pregnant or become pregnant might lead to birth defects, so experimental drugs were mainly tested in men. Research in animals followed the same pattern.

Until very recently it was thought that just one bacterium was to blame for causing Lyme disease in humans. But it turns out that a second, related bug can cause it too.

In 2013, during routine testing of bacterial DNA floating around in the blood samples of people suspected of having Lyme disease, researchers at the Mayo Clinic in Rochester, Minn., realized they were looking at something different.

Genetics researchers often discover certain snips and pieces of the human genome that are important for health and development, such as the genetic mutations that cause cystic fibrosis or sickle cell anemia. And scientists noticed that genetic variants are more common in some races, which makes it seem like race is important in genetics research.

Bill Radke speaks with Washington State University apple researcher Kate Evans about Cosmic Crisp, a new variety of apple she helped develop that will be exclusively grown in Washington state. 

We asked our listeners to weigh in on their favorite varieties, check out their varied responses below!

"Squat! Squat! Squat! Higher! Faster!"

In the basement of the Duane Physics and Astrophysics building at the University of Colorado Boulder, a science demonstration is going on, but it looks more like a vaudeville act.

One by one, students balance precariously on a rotating platform. Then they are handed what looks like a spinning bicycle wheel, holding it by two handles that stick out from either side of what would be the hub of the wheel. When you flip the wheel over, like a pizza, your body starts rotating in the opposite direction.

The Science Of Getting Kids Organized

Feb 2, 2016

If you've ever gotten a glimpse inside a high schooler's backpack or locker, you know organization doesn't always come naturally to teens. Being scatterbrained in school can make make it tough to stay focused and do well.

That was the case when Lilli Stordeur was about halfway through her freshman year of high school in Northampton, Mass. She felt totally overwhelmed.

"I was being tutored for the classes I was having trouble in," she says, "but I would be having a hard time organizing my binders, and notebooks and stuff, and knowing when to hand things in."

The history of science is full of happy accidents — most folks have heard that penicillin was discovered in 1928, when a few mold spores landed on some neglected petri dishes in a London lab. But sometimes serendipity's role is a bit less ... mainstream.

Regulators in the UK today approved research on human embryos using CRISPR-Cas9, a controversial form of gene editing that has been exciting scientists and alarming bioethicists around the world.

Praying for rain? You'll get (slightly) less when the moon is very high, a new study finds.

Scientists at the University of Washington say the moon's position impacts the amount of rainfall on Earth.

"As far as I know, this is the first study to convincingly connect the tidal force of the moon with rainfall," researcher Tsubasa Kohyama says in a press release from the university.

Editor's note at 10:51 a.m. ET, Feb. 1: The original version of this post lacked a perspective from the food industry. That post also may have given the impression that NPR has a position on whether food ads should or should not be banned. A new version appears below and the original version follows.

Why is it that we haven't seen ads for cigarettes on television since the Nixon administration?

Some octopuses intimidate their neighbors by turning black, standing tall and looming over them threateningly, like an eight-armed Dracula.

That's according to a study published Thursday that helps show that octopuses aren't loners, contrary to what scientists long thought; some of the invertebrates have an exciting social life.

Tracing your genealogy has become a popular hobby in the United States. More than 1 million people around the country have taken these tests. Shows like PBS's Finding Your Roots have shown the public how much information you can find out about your family tree with a simple DNA test.

Editors' note, Feb. 1, 2016: On Jan. 20, we reported on a statement from the American Psychological Association that a research paper, "Chronic Adolescent Marijuana Use as a Risk Factor for Physical and Mental Health Problems in Young Adult Men," had a statistical error. The APA now says that statement, which was titled "APA Corrects Article Regarding Teen Marijuana Use," should not have said there was an error in the paper. Jim Sliwa, a spokesman for the APA, told NPR: "There was no error.
