Science, Spoken

What began in mid-December as a mysterious cluster of respiratory illnesses has now killed at least six people, sickened hundreds more, and spread to five other countries, including the US. On Tuesday, American health officials confirmed the nation’s first case of the novel coronavirus: a Washington man hospitalized outside of Seattle last week with pneumonia-like symptoms.

We like to think modern culture moves at a dizzying pace, fueled by a relentless parade of new works of music, literature, and technological design. Change in nature, by contrast, seems to follow a slower trajectory as genetic mutations over generations give animals bigger teeth, say, or a better camouflage. But maybe the opposite is true, and human culture doesn’t move so fast and we consumers ar...

On the day Susan Gordon learned Venetucci Farm, in Colorado, was contaminated by toxins, the vegetables looked just as good as ever, the grass as green, and the cattle, hogs, chickens, and goats as healthy. The beauty of the community farm she and her husband managed made the revelation all the more tragic. Chemicals known as per- and polyfluoroalkyl substances, invisible and insidious, had tainte...

Under the watchful eye of a microscope, busy little blobs scoot around in a field of liquid—moving forward, turning around, sometimes spinning in circles. Drop cellular debris onto the plain and the blobs will herd them into piles. Flick any blob onto its back and it’ll lie there like a flipped-over turtle. Learn more about your ad choices.

Cats are scientifically, objectively, monumentally terrible for the planet. In the US alone, free-ranging domestic cats kill up to 3.7 billion birds and 20.7 billion mammals a year, to say nothing of reptiles and amphibians. They are a scourge of the highest order. Now felines are poised to exacerbate the ecological crisis unfolding in Australia as an unprecedented fire season rips across the cont...

Australia’s wildfires are burning with such intensity that they’re sparking contained, small-scale weather systems. Thunderstorms triggered by atmospheric disturbance might at first seem to offer relief in the form of raindrops, but instead, bolts of lightning can strike nearby trees and spread the fire even further than before.

Lithium-ion batteries have shaped the modern world. These power pouches are at the heart of most rechargeable electronics, from cell phones and laptops to vapes and electric cars. But while they’re great at holding charge and have a high energy density, lithium-ion batteries aren’t without their problems. Their reliance on toxic, flammable materials means the smallest defect can result in explodin...

That burning feeling in your chest after you eat a heavy meal could be heartburn. Or it could be worry over the drugs you’ve taken to treat that heartburn. Among the top medical stories of 2019 was the discovery of contaminants in common medicines, and ranitidine—best known as Zantac—took up a large share of those headlines. A cancer-causing substance known as NDMA has been repeatedly found in one...

Australians haven’t seen anything like the bushfires currently tearing through their country. The conflagrations are obliterating landscapes and their ecosystems, reshaping the continent in irreparable ways. Bushfires aren’t supposed to behave like this. In a normal world, every so often a lightning-sparked fire will roll through a landscape, clearing away old foliage to make way for the new. Lear...

Dark energy, mysterious as it sounds, has become part of the furniture in cosmology. The evidence that this repulsive energy infuses space has stacked up since 1998. That was the year astronomers first discovered that the expansion of the universe has been speeding up over time, with dark energy acting as the accelerator. As space expands, new space arises, and with it more of this repulsive energ...

For many of us, winter, with its chilly days and long nights, brings with it a general sense of malaise. It’s harder to peel ourselves out of bed in the half-light of morning, and hunched over our desks at work, we can feel our productivity draining away with the remnants of the afternoon sun.

Babies love it, and Galileo supposedly tried it: Drop some objects from on high, and see how fast they fall. According to Einstein’s theory of general relativity, all objects in Earth’s gravity, regardless of mass, should descend at the same rate in the absence of air resistance. But there are plenty of reasons to believe this might not be true. Learn more about your ad choices. Visit podcastchoic...

There's a rare human trait that doesn't often make it into debates about what makes our species unique: menopause. Humans are among just a handful of species where females stop reproducing decades before the end of their lifespan. In evolutionary terms, menopause is intriguing: how could it be advantageous for reproductive ability to end before an individual's life is over? One possible answer: th...

Just about a year ago, SpaceX sent the rocketry equivalent of a clown car to space: A rocket crowded with more than 60 small satellites. Inside one of them, Excite, were even more. It was actually a satellite made of other satellites, all clones of each other, all capable of joining together and working together. It was one of the first in-space tests of such a contraption—but in the coming years,...

This story originally appeared on Yale Environment 360 and is part of the Climate Desk collaboration. From 2011 to 2016, California experienced five years of extreme drought, during which numerous high temperature records were broken. These hot, dry years were followed by the extremely wet winter of 2016 -2017, when, from October to March, an average of 31 inches of rain fell across the state, the...

At this very moment, you're a participant in one of the things that makes us human: the telling and consumption of stories. It's impossible to say when our species began telling each other stories—or when we first evolved the ability to use language to communicate not only simple, practical concepts but to share vivid accounts of events real or imagined. But by 43,900 years ago, people on the Indo...

It’s a brisk December morning at Spaceport Tucson, America’s premiere (only?) dedicated launch pad for stratospheric balloons, and a small army of technicians in reflective vests is milling around on the concrete and dethawing after a long, cold night. Nearby, a white metal tripod the size of a smart car is tethered to two dozen solar panels and hundreds of feet of clear plastic that stretches acr...

This story originally appeared on Undark and is part of the Climate Desk collaboration. When most people conjure a forest, they imagine a dense network of trees, their crowns arching high above, with spots of sunshine flashing between the leaves. Some might also think of birdsong and insects, or summon thoughts of thick foliage in the understory, the crunch of leaves or pine needles underfoot, or...

Flu season is good for no one. The infection kills thousands of people every year, while many more spend days suffering in bed. Kids get infected. Then the virus flattens the parents who stay home with them. Even dogs are laid low. Except there is one entity that kinda loves the flu. Telemedicine companies are hoping to use the annual scourge as a lure for new customers. When the days get shorter...

For hundreds of millions of years, sharks have been roaming Earth’s oceans making meals out of a huge range of critters, from the whale shark gobbling up tiny krill to the 60-foot megalodon that could take down whales. Their ancestral line has survived mass extinctions with ease, most notably the catastrophe that took down the dinosaurs. Learn more about your ad choices. Visit podcastchoices.com/a...

From the beginning of time, humankind has searched for the secret to a long life. Now science may have found an answer, in the form of molecular augury. The pattern of chemical chains that attach to the DNA in your cells—on-off switches known as epigenetic markers—can reveal how swiftly you are aging, and perhaps even how much longer you will live. While genetic testing might tell you where you ca...

Nearly 6,000 years ago, in a seaside marshland in what is now southern Denmark, a woman with blue eyes and dark hair and skin popped a piece of chewing gum in her mouth. Not spearmint gum, mind you, but a decidedly less palatable chunk of black-brown pitch, boiled down from the bark of the birch tree. An indispensable tool in her time, birch pitch would solidify as it cooled, so the woman and her...

There’s a cruel irony in the fact that holiday travel tends to coincide with the rise of flu season. Yet more than 47 million Americans are preparing to sit for hours inside a tube in the sky, perhaps near someone with a hacking cough. It sounds like the perfect (infectious) storm. But reaching your destination without collecting microbial stowaways isn’t as daunting as it seems. Learn more about...
