The Supreme Court hears a case centering on the FDA’s denial of applications for nicotine-based vapes containing flavored liquid seen as addictive for young people. And, damaged lithium-ion batteries can cause deadly explosions. An algorithm could help detect when they’re about to happen.Supreme Court Hears Case On FDA Regulation Of Flavored VapesOn Monday, the US Supreme Court heard arguments in a case that could change the Food and Drug Administration’s power to regulate nicotine-based vapes. It revolves around the FDA’s denial of applications from two vape companies that sell flavored liquids in their products, citing that the liquids presented a danger in addicting young people to nicotine. But a lower court rejected that denial, saying the agency was inconsistent in its approval process. The decision could impact the FDA’s regulatory power to ban the sale of some of these vapes in the US.Ira Flatow is joined by Rachel Feltman, host of the Popular Science podcast “The Weirdest Thing I Learned This Week,” to talk about the health implications of the case. They also discuss other top science stories of the week, including why there’s been a large decrease in cervical cancer rates over the past decade, why Venus probably wasn’t able to support ancient life (contradicting some hopeful theories), and new information about when humans might’ve started to wear clothing, thanks to some clues from lice.A Warning For When A Lithium-Ion Battery Is About To ExplodeLithium-ion batteries are used in all sorts of electronics, like smart phones, laptops, and e-bikes. That’s because they can store a lot of energy in a small package. Unfortunately, this also means that when a battery is damaged, there’s a lot of energy to expel, which can lead to explosions and fires.While there are no national statistics available, in New York City alone, there have been 733 fires started by lithium-ion batteries since 2019, which killed 29 people and injured 442. Most of these fires are a result of e-bike or scooter batteries catching fire.Now, researchers have trained AI algorithms to be able to better predict when a lithium-ion battery is about to explode. The battery makes a hissing sound two minutes before an explosion.Ira talks with two researchers at the National Institute of Standards and Technology about their work on the subject: Dr. Andy Tam, mechanical engineer in the Fire Research Division, and Dr. Anthony Putorti, fire protection engineer and leader of the Firefighting Technology Group.Transcripts for each segment will be available after the show airs on sciencefriday.com.
