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 happ...

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 intelli...

Dirty Diapers Reveal How Germy Babies’ Microbiomes Are In a new study, researchers picked through the dirty diapers of more than 600 infants. 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 . Guest host and SciFri producer Kathleen Davis talks with Katherine J. Wu,...

How do we use art to process the world around us in ways that science can’t? How are illustrators using their skills to help us understand nature’s most unusual creatures? On Universe of Art, a new podcast from Science Friday, hosted by SciFri producer and art nerd D Peterschmidt, we bring you some of our favorite arts stories from the show, some new ones too, and conversations with the producers...

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...

How We Arrived At Current Standards Of Care For Trans Medicine So far this year, 16 states have moved to restrict or completely ban transgender kids access to gender affirming care. And 17 other states are considering similar laws, a handful even trying to restrict care for adults. This political controversy has drawn increased attention to “Standards of Care,” a set of guidelines written by the W...

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 f...

EPA Proposal To Require 60% Of New Cars To Be EVs by 2030 The EPA released a set of proposals this week that would cap C02 emissions for new cars. 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. Ira talks with Casey Crownhart, Climate Reporter for the MIT Technology Review,...

An Open Letter Asks AI Researchers To Reconsider Responsibilities In recent months, it’s been hard to escape hearing about artificial intelligence platforms such as ChatGPT, the AI-enabled version of Bing, and Google’s Bard—large language models skilled at manipulating words and constructing text. The programs can conduct a believable conversation and answer questions fluently, but have a tenuous...

Your Plants Are Trying to Tell You They’re Thirsty Spring is in the air, with flowers blooming and gardens starting. 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 jou...

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...

A Supermassive Black Hole The Mass Of 30 Billion Suns This week, astronomers reported that they may have found signs of one of the largest black holes ever detected –a space behemoth the mass of some 30 billion suns. The supermassive black hole, located in part of the Abell 1201 galaxy cluster, was detected using a combination of gravitational lensing and supercomputer simulations. First, the astr...

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 Flo...

The Latest IPCC Report Is Full Of Warnings—And Hope It’s that time of year: another IPCC report has hit the presses. These reports from the Intergovernmental Panel on Climate Change are like a check up—to let us know how we’re doing on the climate front and what Earth’s future is projected to look like. And to no one’s surprise, this year’s report is full of warnings. But also, it has a lot of roo...

Stop Flushing Your Health Data Down The Toilet You could be flushing important information about your health right down the toilet—quite literally. Pee and poop can tell you a lot about your health, so what if your waste…didn’t go to waste? What if, instead, it could tell you more about your health? Like number one, it can catch a condition like diabetes early. Or number two, check out what’s goin...

At Long Last, More Regulations For Forever Chemicals This week, the EPA proposed the first national standards for drinking water that would set limits on the amount of PFAS (per- and polyfluoroalkyl substances) chemicals that would be allowed in water systems. There are thousands of different PFAS chemicals, which are often used industrially for properties such as heat, water and stain resistance—...

Tips And Tricks To Grow Your Garden In A Changing Climate For many of us, spring is right around the corner—or already here—which means it’s time to start thinking about what is going into your garden this year. But largely thanks to climate change, our seasons are getting wonkier every year. Gardens are feeling the heat as climate change affects the timing of the seasons, temperature extremes, th...

Despite Superconductor Breakthrough, Some Scientists Remain Skeptical This week, researchers unveiled a new superconductor which they say works at room temperature .
