How The Humble Beaver Shaped A ContinentThe American beaver, Castor canadensis, nearly didn’t survive European colonialism in the United States. Prized for its dense, lustrous fur, and also sought after for the oil from its tail glands, the species was killed by the tens of thousands, year after year, until conservation efforts in the late 19th century turned the tide. In her new book, Beaverland: How One Weird Rodent Made America, author Leila Philipp tells that tale—and the ecological cost of this

Meet The Blind Birder Reimagining Accessibility In The OutdoorsFor many blind and low vision people, accessing outdoor spaces like parks can be challenging. Trails are often unsafe or difficult to navigate, signs don’t usually have Braille, guides generally aren’t trained to help disabled visitors, and so on. But nature recordist Juan Pablo Culasso, based in Bogata, Colombia, is changing that. He’s designed a system of fully accessible trails in the cloud forests of southwest Colombia that are

An interdisciplinary group of scientists, researchers, and artists are using queerness as a lens to better understand the natural world, too. It’s a burgeoning field called queer ecology, which aims to break down binaries and question our assumptions of the natural world based on heterosexuality. For example, there are

Scientists Can Now Hear The Background Hum Of The UniverseFor the first time ever, scientists have heard the “low pitch hum” of gravitational waves rippling through the cosmos. It’s this ever-present background noise set off by the movement of massive objects—like colliding black holes—throughout the universe. Scientists have theorized that it’s been there all along, but we haven’t been able to hear until now. So what does this hum tell us about our universe? SciFri producer Kathleen Davis talks

Curly Hair Keeps Your Scalp CoolerAccording to a fascinating new study, curly locks are better than straight hair at keeping your scalp cool. Researchers shone bright lights on three different manikins—one with no hair, one with loosely curled hair and another with tight curls. Solar radiation bounced off the tightly curled hair, and less heat reached the manikin’s scalp than the straight haired manikin. The manikin with loose curls was right in the middle. The research is part of an effort to

Why Have Ocean Temperatures Spiked?Sea surface temperatures in the North Atlantic have risen dramatically in recent weeks, to as much as 0.5 degrees Celsius warmer than the previous record—and over 1 degree C warmer than average temperatures from 1982 to 2011. The reason for the unusually toasty waters isn’t entirely clear. Some climatologists attribute part of the rise to an El Niño ocean circulation pattern this year, replacing the La Niña pattern that had been suppressing temperatures. Other

Exposing Texas’ Excess Emissions Problems In the early hours of August 22, 2020, Hurricane Laura was still just a tropical storm off the coast of the Leeward Islands in the Caribbean. But effects from the monstrous storm, which would ultimately take at least 81 lives, were already being felt on the U.S. Gulf Coast. As rain poured down on the Sweeney refinery in Old Ocean, Texas, that afternoon, two processing units failed, releasing nearly 1,400 pounds of sulfur dioxide, which can cause trouble

To do so, they enlisted volunteers from all over the world. Over 1,000 people have participated so far. You can even buy the seeds and plant them in your own

Could Restoring Animal Populations Store More Carbon? Did you know that land and ocean ecosystems absorb about half of the carbon dioxide we emit each year? But what if the earth had the capacity to absorb even more? With the help of some furry, scaly, and leathery critters, maybe it can. A recent study in the journal Nature Climate Change claims that by restoring the populations of just a handful of animals—like gray wolves, bison, and sea otters for example—the Earth could capture around 6.41 more

But when the harmful chemical is a radioactive element, options are limited. Iodine pills can be used to help block radioactive iodine I131 from being absorbed by the thyroid, but there aren’t many other drugs that can help deal with contamination with other radioactive substances. One of the two existing medications can
