766: What Martian Geology Can Teach Us About Earth

Science Friday ·

2024/05/08

At first glance, Mars might seem rather different from our own planet. Mars is dry, with little atmosphere, and no liquid water on its surface. It is half the size of Earth, lacks a planetary magnetic field, and does not appear to have active plate tectonics or volcanic activity. In some ways it is a world frozen in time, affected only by the force of wind and the occasional meteorite impact. That static nature, however, could give scientists clues to conditions that once existed on Earth, but have

765: How Louisiana Is Coping With Flooding In Cemeteries

Science Friday ·

2024/05/07

Emily Dalfrey lives across the street from Niblett’s Bluff Cemetery, where generations of her family are buried, in Vinton, Louisiana. In 2016, a period of prolonged rainfall caused flooding so severe that people could drive boats over the cemetery. The water put so much pressure on the graves that some of the vaults, which are located near the surface, popped open. Some of Dalfrey’s own family members’ caskets were carried away and deposited in her yard. Unsure how to restore the cemetery, the

A study found aggression between male bonobos to be more frequent than aggression between male chimpanzees. Also, visual artist Todd Gilens created a walkable poem along Reno’s Truckee River that draws parallels between urbanism and stream ecology. Bonobos Are Gentler Than Chimps? Maybe Not. Bonobos are a species of great ape, along with gorillas, orangutans, and chimpanzees. Over the years, they’ve gained a reputation as being calmer and more peaceful than other ape species.

There are products on the market that monitor your brain waves through caps or headbands: Some aim to improve mental health, sleep, or focus, while others can plunge users into virtual reality for gaming. What happens to the neural data that neurotechnology companies collect from these devices? Consumers may be accustomed to their personal data from apps and social media being sold to third parties. However, the potential sale of brain data to a third party raises additional privacy concerns. There

760: Visualizing A Black Hole’s Flares In 3D

2024/04/30

The words “black hole” might bring to mind an infinite darkness. But the area right around a black hole, called the accretion disk, is actually pretty bright, with matter compressing hotter and hotter into a glowing plasma as it is sucked in. And amid that maelstrom, there are even brighter areas—bursts of energy that astronomers call flares. Scientists are trying to better understand what those flares are, and what they can tell us about the nature of black holes. This week in the journal Nature

2024/04/29

Silk is one of the most luxurious fabrics for clothing and bedding. Unlike cotton or linen, silk is made most commonly by insects—often the Bombyx mori, a domesticated moth that feeds on the leaves of mulberry trees. Humans have a 4,000-year history with the textile and the creatures that make it, as documented in the new book Silk: A World History. Since silk has an unconventional origin as a secretion rather than a plant product, it has unique biological qualities that make it strong and enduring

While progress has been made in replacing water pipes in Flint, many residents say they still don’t know if their tap water is clean or not. Also, scientists are adding sensors to an underwater cable network to monitor changes in the ocean and quickly detect earthquakes and tsunamis. 10 Years Later, Flint’s Water Crisis Still Isn’t Over In 2014, city officials in Flint, Michigan, switched their water source to the Flint River, a move that was projected to save the city $5 million.

Last year, almost half of the honeybee colonies in the U.S. died, making it the second deadliest year for honeybees on record. The main culprit wasn’t climate change, starvation, or even pesticides, but a parasite: Varroa destructor.“The name for this parasite is a very Transformer-y sounding name, but … these Varroa destructor mites have earned this name. It’s not melodramatic by any means. [They are] incredibly destructive organisms,” says Dr. Sammy Ramsey, entomologist at the University of

It wasn’t that long ago that scientists didn’t think animals could rival humans in terms of intelligence, emotions, or empathy. But the groundbreaking work of Dr. Frans de Waal helped change all of that. De Waal spent his life studying the lives of animals — especially our closest cousins, chimpanzees and bonobos. The primatologist died last week at the age of 75, and we wanted to remember him by sharing one of our favorite conversations with him on the show. It’s from 2019, when he published his

Ever since we learned that an asteroid slammed into Earth, wiped out the dinosaurs, and changed the course of life on this planet, scientists have wondered if it could happen again. It turns out there is an asteroid, called Bennu, that has a very small chance of colliding with our planet in the year 2182. But beyond that, Bennu could hold information that would help unlock our solar system’s secrets, like how it began and where life originated. NASA’s OSIRIS-REx mission launched in 2016 to collect a

The next time you go to the zoo, take a few minutes by the sea lion habitat to watch the way they swim. While most high-performance swimmers use powerful kicks from hind appendages to power through the water, sea lions instead use their front flippers, moving with a pulling motion. With their propulsion source close to their center of gravity and their flexible bodies, sea lions are extremely agile under water, able to weave in and out among the stalks of an undersea kelp forest.

It’s a common refrain from elementary school to adulthood: “I’m bad at math.” It’s a hard subject for a lot of people, and it has a reputation for being—let’s face it—boring. Math isn’t taught in a flashy way in schools, and its emphasis on memorization for key concepts like multiplication tables and equations can discourage students.It’s not hard to understand why: Math has long been seen as a boy’s club, and a straight, cis boy’s club at that.

Some can sleep for over 24 hours, despite using stimulants and multiple alarm clocks. Others fall asleep while driving or doing other daily activities. IH is rare.
