This past year, 2017, was the worst fire season in American history. Over 9.5 million acres burned across North America. Firefighting efforts cost $2 billion. This past year, 2017, was the seventh-worst Atlantic hurricane season on record and the worst since 2005. There were six major storms. Early estimates put the costs at more than $180 billion. As the preventable disease hepatitis A spread thr...

Academics have been cast in a slow-motion horror movie for the past couple of years, as superstar scientist after superstar scientist has been pushed from his pedestal for allegations of sexual harassment. Societies and universities have tried to determine what to do—academe-style fixes like panels, workshops, and policies. None of that ivory-tower work cued the public crescendo that this year’s r...

In fewer than five years, the gene-editing technology known as Crispr has revolutionized the face and pace of modern biology. Since its ability to find, remove, and replace genetic material was first reported in 2012, scientists have published more than 5,000 papers mentioning Crispr. Biomedical researchers are embracing it to create better models of disease. And countless companies have spun up t...

Kelly Brunt won’t be home for the holidays, nor will she be ringing in the New Year at a fabulous party or watching Ryan Seacrest schmooze B-list celebrities on TV. Instead, between December 21 and January 11, she’ll be leading a four-person expedition around the South Pole, sleeping in a small tent mounted on a plastic sled that is pulled by a snowcat.

This year, for the first time in my life, I’ll be hosting my family for the holidays. And to their deep disgruntlement, we’ll be celebrating it without a Christmas tree. No, this isn’t some principled stance against the yuletide-industrial complex or a personal front in the war on Christmas. I’m just much more interested in an indoor evergreen interloper when its needles fall in someone else’s hom...

Ocean explorers and entrepreneurs have been thinking about how to scoop up mineral-laden deposits on the seafloor since the HMS Challenger dragged a few up in a bucket during its globe-trotting scientific voyage in the 1870s. A century later, the CIA used deep sea mining as a cover story for a secretive plan to recover a sunken Russian nuclear sub. Now, it’s a serious engineering proposition. Lear...

I can't decide if this looks like something from a super hero movie or from a video game. In this compilation video of crazy stunts, a guy somehow finds a way to bound up between two walls by jumping from one to the other. "Somehow," of course, means with physics: This move is based on the momentum principle and friction. Could you pull it off? Probably not. But you can at least do the math. Learn...

If you’ve been putting off your flu shot until the season really gets going, wait no longer. It’s already here—and it’s looking like it’s going to be a doozy. Influenza viruses quietly circulate year-round in the US, but every winter they go big, triggering a seasonal epidemic of sniffles, sweats, and sore throats. And this year it’s come earlier than usual, just in time for a potential peak over...

Saturn's rings sure are pretty, and Matt Damon’s been to Mars, but our eight-planet solar system may not be that special after all. Today, scientists using data from NASA’s Kepler spacecraft announced they’d discovered an eighth planet orbiting a star 2,500 light years away. They’ve named the planet Kepler-90i after the star it orbits, Kepler-90, which is slightly hotter and more massive than our...

Let me freak you out for a second. You know what bitcoin is, right? I mean, no, but quickly, it’s a “cryptocurrency” that’s basically secret computer money. One bitcoin, which doesn’t actually have a real, physical form, is worth at this moment upwards of $16,000. But to get one, you either have to buy them from online exchanges or use specialized computing hardware to “mine” it. That last bit is...

Neill Stollman has been called the Tupac of poop transplants. The Oakland-based, board-certified gastroenterologist didn’t invent the treatment. But he did bring it to the west coast. His first patient was a woman in her 80s with a horrible case of Clostridium difficile, a gut infection that can strike patients after a course of antibiotics clears out their existing bacterial community.

In late 2012, French microbiologist Emmanuelle Charpentier approached a handful of American scientists about starting a company, a Crispr company. They included UC Berkeley’s Jennifer Doudna, George Church at Harvard University, and his former postdoc Feng Zhang of the Broad Institute—the brightest stars in the then-tiny field of Crispr research. Back then barely 100 papers had been published on t...

Figuring out how human beings do human things is one of the most exciting things that science—psychology, sociology, economics, anthropology—can do. It’s also one of the hardest. Reliable, meaningful methods that distill real-world behavior into experimental variables have been, let’s say, elusive. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Sometimes, when I'm proctoring an exam, I end up with a little too much time on my hands. So I play with stuff—whatever I've got on hand. In this case, it was one of those clicky pens. It had stopped writing, so I assumed it was out of ink. Of course it might not be out of ink, so I took it apart to look at the ink cartridge and check. That's when I discovered the fun stuff: If I push the empty in...

Humans have gotten pretty good at launching stuff into space—but way less good at getting stuff back down. Up in lower Earth orbit, along with a thousand-plus productive satellites, there are many more slackers: space junk, cosmic trash, garbage of the highest-orbiting order.

Big offshore wind farms power Europe’s drive for a carbon-free society, while rows of spinning turbines across America’s heartland churn enough energy to power 25 million US homes. But a new study predicts that a changing climate will weaken winds that blow across much of the Northern hemisphere, possibly leading to big drops in clean wind energy.

Today, a teaspoon of spit and a hundred bucks is all you need to get a snapshot of your DNA. But getting the full picture—all 3 billion base pairs of your genome—requires a much more laborious process. One that, even with the aid of sophisticated statistics, scientists still struggle over. It’s exactly the kind of problem that makes sense to outsource to artificial intelligence. Learn more about y...
