The foot-long meteor passed through the Earth’s atmosphere near the Statue of Liberty. Don’t worry, it was fine. Also, the follow-up to the 1996 movie “Twister” is a whirlwind of tornado science. A weather expert decodes its lingo—and real-life tornado trends.A Small Meteor Blazes Over New York CityTuesday morning, some New York area residents heard a loud boom and saw a daytime fireball streaking overhead. According to observers, a small meteor entered the Earth’s atmosphere over New York City, passed by the Statue of Liberty, and proceeded west to New Jersey, moving at some 38,000 miles per hour. Meteor experts said that the object, estimated to be around a foot in size, posed no threat, as debris from an object that small would have burned up before reaching the ground.Science Friday’s Charles Bergquist joins guest host Rachel Feltman to talk about the overhead display, and about other science news from the week, including a newly planned mission to fly by a near-Earth asteroid. They’ll also talk about a new pool of data for human genetics research, efforts to predict rogue waves, and the challenges of making food taste right in orbit.The Tornado Science To Know Before Seeing ‘Twisters’“Twisters,” the long awaited follow-up to the 1996 movie “Twister” drops in theaters today, July 19. It’s about a scientist (Daisy Edgar-Jones) who goes back to her home state of Oklahoma to try and stop a massive tornado outbreak from wreaking havoc on its citizens. On the way, she meets a quirky cast of storm chasers, and butts heads with a band of unorthodox “tornado wranglers” led by a YouTube personality (Glen Powell). “Twisters” delights in name-dropping tornado jargon, and its science advisory team said they hoped to make the movie as accurate as possible.The movie makes science thrilling, but it also shows the ways that tornadoes affect people’s lives in the real world. For example, earlier this week, the Chicago area was hit with multiple tornadoes during a night of extreme weather, leaving thousands without power, and four tornadoes hit upstate New York, killing one person. This comes after a powerful, and some say unusual, tornado season in the Midwest. But just how tornadoes will continue to change is still unknown.Digital producer Emma Gometz talks with Dr. Bill Gallus, a meteorology professor at Iowa State University, to decode some of the science from “Twisters” and understand how real-life tornadoes are changing.Transcripts for each segment will be available after the show airs on sciencefriday.com.

If you’ve tried to get prescriptions filled in the last year or so, a pharmacist may have told you, “Sorry, we don’t have that drug right now.” That’s because there are some 323 active and ongoing drug shortages in the United States. That’s the highest number of such shortages since the American Society of Health System Pharmacists started tracking this data back in 2001.These drug shortages touch every part of the healthcare system. Doctors are having to reconfigure their treatment plans due to short supply of certain drugs, like cancer treatments. And patients can be left going from pharmacy to pharmacy to get even the most common medications, like antibiotics.SciFri’s John Dankosky talks with freelance journalist Indira Khera and journalist and physician Dr. Eli Cahan, who looked into why drug shortages happen, how they’re affecting the healthcare system, and what solutions are on the horizon.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The gut microbiome is an important ecosystem of microbes that lives in each one of us, and its strength affects our overall health.However, the small intestine is an underappreciated part of the gut microbiome. Most of the research into our microbiomes has focused on the other end of the gastrointestinal tract, namely, the colon. And poop samples are an easy way to analyze the microbiome in that lower part of the gut.Better understanding microbiome disruptions in the small intestines may allow researchers to better understand disorders like irritable bowel syndrome, and celiac disease. Dr. Christopher Damman, associate professor of gastroenterology at the University of Washington, gives SciFri producer Kathleen Davis a crash course in the microbiome of the small intestine.Transcripts for each segment will be available after the show airs on sciencefriday.com.
