Science Friday Folgen

From down here on Earth, life on the International Space Station seems magnificent: floating through the day, enjoying stunning views out your window, having an experience only a handful of other people will ever get.But what’s it really like to live up there? How does experiencing 16 sunrises and 16 sunsets every day change your perception of time? How do you cope with being so far from the people you love?Those are some of the questions explored in the novel Orbital, which won the Booker Prize late last year. In the book, author Samantha Harvey imagines the inner life of astronauts aboard the ISS.Host Flora Lichtman is joined by Samantha Harvey, along with astronaut Dr. Cady Coleman, who spent almost six months on the Space Station, and is an author herself. They talk about the unexpected mundanities of living in space, how Harvey was inspired to write the book during lockdown, and how astronauts make sense of their new reality when separated from the rest of humanity.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Since January 7, wildfires have been devastating the Los Angeles area. In the span of 10 days, several different fires, including the Palisades and Eaton fires, have burned more than 40,000 acres and destroyed more than 12,000 structures. At least 25 people have died.The threat of fire is growing, especially in zones known as the wildland-urban interface, or WUI. That’s where unoccupied wildland and human developments meet and mingle. Think of a city sprawling around a forest, for example. In the US, around one in three homes is in this type of high-risk zone.So what’s the science behind urban fires? And how do we protect ourselves in the face of them?Ira Flatow talks with Dr. Kimiko Barrett, senior wildfire researcher and policy analyst at the research group Headwaters Economics in Bozeman, Montana; and Dr. Alexandra Syphard, senior research scientist at the Conservation Biology Institute in San Diego, California.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The SpaceX rocket carries lunar landers from companies based in Texas and Japan. They could arrive at the moon in the coming months. HPV can cause a variety of cancers, including cervical. New mortality data for women under 25 point to the success of the HPV vaccine.Rocket Launches With Lunar Landers From 2 Private CompaniesOn Wednesday, a SpaceX rocket launched carrying payloads from two separate private companies hoping to achieve lunar landings. The pair of landers—one from Japanese company ispace, and one from Texas-based Firefly Aerospace—will take months to reach the moon. Firefly’s lander is scheduled to arrive first, in March, with ispace’s lander planned for a touchdown in late May or early June.Another SpaceX launch on Thursday, a test flight of the company’s Starship system, had mixed results. The booster returned to earth and was successfully “caught,” but the spacecraft exploded over the Caribbean shortly after launch. That explosion is under investigation.Jason Dinh, climate editor at Atmos in Washington, D.C., joins Ira to talk about the Wednesday launch and plans for private lunar exploration. They also discuss other stories from the week in science, including the ban of Red Dye #3 an AI approach to snake antivenom, and a study predicting a rise in US dementia cases by 2060.As Cervical Cancer Deaths Plummet, Experts Credit HPV VaccineIn 2006, a vaccine for the human papillomavirus (HPV) became widely available to adolescents. HPV is the most common sexually transmitted infection, and it can cause cancers of the mouth, throat, and sexual organs. It’s also the cause of nearly every case of cervical cancer.Now, almost 20 years after the HPV vaccine was introduced, a study published in JAMA noted a 62% drop in deaths due to cervical cancer in women under 25 in the US: from 50 or 60 deaths per year to 13. This follows earlier research that noted a decrease in cervical precancer and cancer since the introduction of the vaccine.With HPV vaccine uptake at about 60% for adolescents aged 13-15, a higher uptake could virtually eliminate cervical cancer, experts say. However, childhood vaccination rates have dwindled since the start of the COVID-19 pandemic, sparking concerns about the spread of preventable disease.Joining Flora Lichtman to talk about this latest study is lead author Dr. Ashish Deshmukh, professor of public health sciences and co-leader of the Cancer Prevention and Control Program at the Medical University of South Carolina in Charleston, South Carolina.Transcripts for each segment will be available after the show airs on sciencefriday.com.
