A common worry among older adults is how their brains and bodies might decline as they age.A small but fortunate group will live past their 95th birthdays, while staying cognitively sharp and free of major health complications. They’re called “SuperAgers.”Researchers are working to figure out some of the genetic factors behind SuperAgers’ longevity—and how that knowledge might help the rest of the population live longer and healthier lives.Ira talks with Dr. Sofiya Milman, director of Human Longevity Studies at Albert Einstein College of Medicine and the lead researcher of the SuperAgers Family Study; and one of the study’s participants, Sally Froelich, a 95-year-old New York resident.Transcript for this segment will be available after the show airs on sciencefriday.com.

For years, Asheville, North Carolina, has been billed as a “climate haven,” a place safe from the touch of climate change-exacerbated disasters. But last month, Hurricane Helene called that label into question. Some of the worst damage of the storm occurred inland, in Western North Carolina.Data visualization designer David McConville lived in Asheville for about 20 years, before moving to California.“Watching people idealize Asheville was a little bit crazy-making,” McConville says. “There were very clear patterns of the combination of the topography and hydrology, weather patterns, and development patterns that were creating these dangers,” he says, referring to the extreme flooding and damage brought on by Hurricane Helene.Resilience and adaptation for communities hit hard by storms is a huge area of conversation for cities. And for places hit hard consecutively, like Florida’s coast after Hurricanes Helene and Milton, that need is even more pressing. Joining Ira to talk about this is Dr. Jesse Keenan, associate professor of sustainable real estate and urban planning at Tulane University in New Orleans, Louisiana; and Dr. Jola Ajibade, associate professor of environmental and climate justice at Emory University in Atlanta, Georgia.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Hurricane Milton caused a major storm surge, but also a reverse one. And, Lake Michigan's surface temperature has been above average nearly every day this year so far. All five Great Lakes are heating up.The Science Behind Hurricane MiltonOn October 9, Hurricane Milton made landfall in Siesta Key, Florida, then barrelled across the state. This comes just a couple of weeks after Hurricane Helene devastated parts of the southeastern US. Hurricane Milton dumped up to 18 inches of rain in some places, flooding cars, homes, and other buildings. Several people are confirmed dead. Around 3 million are without power.Hurricane Milton was expected to cause a 15-foot storm surge, but it appears that the storm surge maxed out at five to six feet. And there wasn’t just a storm surge, but a reverse one.Ira talks with Maggie Koerth, science writer and editorial lead for Carbon Plan, about some of the science of Hurricane Milton. They also discuss other science stories from the week, including President Biden’s new rule for replacing lead pipes, concerns about the security of genetic data with 23andMe, and how to tell if an elephant is left or right-trunked.Lake Michigan Swimmers Enjoy ‘Unsettling’ Warm WaterOn a sunny, mid-September afternoon, Olu Demuren took a running start off the concrete ledge just south of Belmont Harbor and leapt into Lake Michigan for the first time.“I was preparing myself for cold water,” Demuren said. “And this immediately felt very nice.”The water along Chicago’s lakeshore averaged an unseasonable 71 degrees that day. The weather was picturesque too: clear blue skies and temperatures in the mid-80s. Annelise Rittberg watched their friends from the concrete ledge and said the weather felt “deeply abnormal.”“While it’s fun to be out here, it’s also unsettling,” Rittberg said.Lake Michigan is heating up. The lake’s surface temperature has surpassed the running average dating back to 1995 nearly every day this year, according to National Oceanic and Atmospheric Administration (NOAA) data. And it’s not just one Great Lake. All five are warming. The massive bodies of water, which provide drinking water to more than 30 million people, are among the fastest-warming lakes worldwide, according to the federal government’s Fifth National Climate Assessment.Read the full story at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.
