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, <a href="https://www.sciencefriday.com/segments/spacex-rocket-explosion/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">and the combined rocket stack exploded</a>. While a setback for the team, SpaceX head Elon Musk said that a lot had been learned from the flight, and another test launch would take place in several months.
Purbita Saha, senior editor at Popular Science, joins SciFri’s John Dankosky to talk about the launch and <a href="https://www.sciencefriday.com/segments/spacex-rocket-explosion/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">other stories from the week in science</a>, including an Earth Day look at water conservation issues across the country, a new named COVID variant, work on an experimental skin cancer vaccine, and the materials science of Mayan plaster.

Dismantling Myths About Menstruation
Saying the phrase “menstrual blood” or or the word “period” can feel almost dirty. That’s because in the western world, people with periods are taught not to discuss this exceedingly normal biological process. Half the world will menstruate at some point in their lives, and yet <a href="https://www.sciencefriday.com/segments/menstruation-myths-period-book/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">menstruation remains exceedingly under-studied</a>.
Biological anthropologist Kate Clancy dug into the history of menstruation research, and the myriad misconceptions about it, while working on her book “Period: The Real Story of Menstruation.” What she found was <a href="https://www.sciencefriday.com/segments/menstruation-myths-period-book/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">a lack of basic understanding of the biological process, from physicians and menstruators alike</a>. Clancy speaks with guest host Maddie Sofia about the misconceptions of a “normal” menstrual cycle, and other persisting period myths.
Fighting Climate Change With Genetically Modified Trees
Vince Stanley has a saying, which he holds as true in a commercial forest as on a row crop farm: Every acre has a plan. In a wetland he owns in Tattnall County, about 70 miles west of Savannah, downhill from an orderly grove of predictably profitable loblolly pines, he is trying out something new. “Now, look at this guy right here,” Stanley said, pointing out what looked more like a stick in the mud compared to the tupelos growing a few yards away in the deeper water. This stick, surrounded by pin flags and planted about six feet away from its sister, had signs of new life: dark green leaves. “That’s impressive,” Stanley said.
And the germ of the new plan for these acres, is something that, until now, Stanley said he didn’t really have. “We’re just leaving this up to Mother Nature,” he said. “So now with Living Carbon, we’ve gone to Option B.” This nascent tree and 10,499 others are at the heart of Option B, what might be the first effort of its kind in the nation: genetically engineered trees planted in a forest. What’s more, these trees are for sale.

All You Need To Know About Anesthesia
If you’ve ever had surgery, you’ve probably wondered about how anesthesia works, or maybe even lied awake at night anxious about going under. If you’ve ever been there, I’m sure you remember: Right before surgery, you get rolled into the operating room. The anesthesiologist tells you to start counting down from 10. The next thing you know, you’re awake in the recovery room and you don’t remember anything that just happened to you. <a href="https://www.sciencefriday.com/segments/how-does-anesthesia-work/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">How exactly did anesthesiologists manage to get you safely into that state and back out again?</a>
Guest host John Dankosky talks with Dr. Louise Sun, professor of anesthesiology, perioperative and pain medicine at Stanford University Health and Dr. Gunisha Kaur, anesthesiologist, director of the Human Rights Impact Lab, and medical director of Weill Cornell Center for Human Rights at Weill Cornell Medicine <a href="https://www.sciencefriday.com/segments/how-does-anesthesia-work/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">about the basics of how anesthesia works</a>.
