Can Science Find An Antidote to Americium?With some poisons, there’s an antidote — something you can take to block the effects of the poison, or to help remove it from your body. 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

Science Says Eat More BeansBeans are delicious, high in protein, inexpensive, efficient to grow, and an absolute staple in so many cuisines. So why don’t Americans eat more of them? The average American eats 7.5 pounds of beans annually, which is only a few cans of beans every year. The answer is complicated, but one thing is sure: Beans have a PR problem. Ira talks with Julieta Cardenas, a Future Perfect Fellow at Vox, who reported this story. If you’re looking to chef it up, read some of the

A dozen Star Trek television shows have aired over the last sixty years—not to mention countless movies, novels, and comic books. Science concepts have always been integral to the Star Trek franchise: from warp speed travel to dilithium. But how much does the series actually accurately depict?

FDA Advisory Board Approves First Over-the-Counter Birth Control PillThis week an FDA advisory board paved the way for the first over the counter birth control pill, with an unanimous decision 17-0. The FDA must accept the recommendation before the pills are available for sale, which is expected in a few months time. If approved, the progestin-only pill would be manufactured by the company Perrigo, under the brand name Opill. Ira talks with Maggie Koerth, science journalist based in Minneapolis,

SpaceX Explosion Damages Environment Around Launch Site Last Thursday, SpaceX’s South Texas facility was awash in noise and fire, as crowds gathered in South Padre Island and Port Isabel to watch Starship’s first orbital launch. It was the largest and most powerful rocket ever made, standing at around 400 feet tall. Four minutes into the launch, SpaceX detonated the rocket after the SuperHeavy booster failed to separate from the Starship as planned. The launch destroyed the company’s launch pad,

A Dying Planet Offers A Peek Into The Future This week, astronomers reported in the journal Nature that they had spotted a planet approximately the size of Jupiter being swallowed by a star over the course of ten days. The star, called ZTF SLRN-2020, is about 15,000 light-years away from our solar system, but still in our own galaxy. Astronomers had thought this type of planet-engulfing must happen, based on how stars evolve and certain chemical signatures they’ve spotted from inside stars. However,

Why Do Humans Anthropomorphize AI? Artificial intelligence has become more sophisticated in a short period of time. Even though we may understand that when ChatGPT spits out a response, there’s no human behind the screen, we can’t help but anthropomorphize—imagining that the AI has a personality, thoughts, or feelings. How exactly should we understand the bond between humans and artificial intelligence? Guest host Sophie Bushwick talks to Dr. David Gunkel, professor of media studies at Northern

Those stinky diapers were a gold mine of info—they contained more than 10,000 virus species. And though it may sound terrifying, those viruses play a key role in babies’ microbiomes.

An Explosive End For A Massive Rocket This week, SpaceX attempted the first uncrewed orbital test flight of its massive Super Heavy rocket topped with an experimental crew capsule known as Starship. After one aborted launch earlier in the week, the huge rocket successfully lifted off Thursday morning—but minutes later, the Starship component failed to separate from the Super Heavy booster, and the combined rocket stack exploded. While a setback for the team, SpaceX head Elon Musk said that a lot had

Is Anybody Out There? The Quest For Life In Space It’s one of humanity’s biggest fundamental questions: “Is there life elsewhere in the universe?” But despite years of searching, it’s a query that still has no answer. That conundrum also opens up a whole string of other inquiries, from how to best search for signs of life, to whether we’ll be able to make sense of what we’re seeing. The search for life elsewhere can also help us learn about our own existence. How many of what we consider the basic

In order to meet the new stricter targets automakers would need to ramp up electric vehicle manufacturing substantially. By 2030, 60% of new cars would need to be electric.

The programs can conduct a believable conversation and answer questions fluently, but have a tenuous grasp on what’s real, and what’s not.

Most people with a green thumb will know a droopy plant is a signal that it needs water. But new research has found another way that plants will signal that they’re thirsty: emitting staccato popping sounds, too high pitched for the human ears. Elsewhere in the world of science journalism, an argument has been made that elephants have self-domesticated. If true, this would make these

Sewage Is A Biological Necessity, And A Methane Minefield In most cities, once you flush a toilet, the water and waste flows through the sewage system to a water treatment plant. Once it’s there, it goes through a series of chemical and biological processes which clean it up and make the water safe to drink again. But a recent paper in the journal Environmental Science & Technology finds that some of those sewage plants may be having a greater impact on the climate than previously thought. The

Can Medicine Move To Animal-Free Testing? Before a new drug can begin clinical trials in humans, it gets tested on animals. But things are changing. Late last year, Congress passed the FDA Modernization Act 2.0, which cleared the way for new drugs to skip animal testing. Can we expect to phase out animal testing altogether? Is it safe? And what technologies might make that possible? Guest host Flora Lichtman talks with Dr. Thomas Hartung, director of the Johns Hopkins Center for Alternatives to

Like number one, it can catch a condition like diabetes early. Or number two, check out what’s going on in your gut microbiome. That’s the goal of the smart toilet—a device that gets all up in your
