On the very first day of Donald Trump’s second term, he signed an executive order targeting foreign aid programs, especially the U.S. Agency for International Development (USAID).Comprising less than 0.1% of the federal budget, USAID provides international humanitarian and development aid for poverty eradication, education, disease prevention, and medical programs. The Trump administration has cut off funding for these programs and most of the USAID staff was placed on leave or laid off.Since January, hospitals and clinics in places like Thailand, Syria, and India have shuttered; clinical trials on HIV and maternal health have been canceled; and projects on polio, malaria, and tuberculosis prevention have been stopped.Then, this week, the Supreme Court rejected a bid to keep some aid funds frozen. But what does that mean in practice for USAID’s global health initiatives?Host Flora Lichtman talks about the global health implications of dismantling USAID with Dr. Atul Gawande, surgeon and former head of global health at USAID; and Dr. Salim Abdool Karim, epidemiologist and director of the Centre for the AIDS Programme of Research in South Africa.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Scientists aren’t always encouraged to be politically active. But recent political interference by the Trump administration has many fired up. And, the Blue Ghost lunar lander, part of NASA’s CLPS initiative, completed the first fully successful commercial moon landing.Protesters ‘Stand Up For Science’ At Rallies Across The CountryScientists and defenders of science are gathering in cities across the U.S. today as part of Stand Up for Science rallies, events to protest recent political interference by the Trump administration in science funding. The main rally in Washington, D.C. features speakers including Bill Nye, Dr. Frances Collins and Dr. Atul Gawande, and will advocate for ending censorship, expanding scientific funding, and defending diversity, equity, and inclusion.Host Flora Lichtman speaks to science reporter Anil Oza, a Sharon Begley Fellow at STAT and MIT, about the runup to Stand Up For Science, and what he’s heard from organizers and attendees. Then, Flora speaks with two listeners, D.C.-based planetary scientist Mike Wong and University of Louisville student Emily Reed, about why they’re fired up to attend local rallies. Touchdown For The Blue Ghost Lunar LanderLast weekend, the Blue Ghost lander, built by the Texas-based company Firefly Aerospace, became the first commercial spacecraft to execute a fully successful landing on the surface of the moon. On board the lander were 10 NASA instruments flown as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative. The lander will be in operation on the moon over the course of one lunar day (about 2 Earth weeks), before running out of battery power as the lunar night falls.Kevin Scholtes, an engineer at Firefly Aerospace, and Dr. Nicky Fox, associate administrator for the NASA Science Mission Directorate, join Host Flora Lichtman to talk about building a commercial spacecraft, the role of private companies in spaceflight, and some of the science the mission aims to achieve.Transcripts for each segment will be available after the show airs on sciencefriday.com.

Last year, 9,000 deceased donor kidneys were discarded due to storage and time limitations. A kidney “life support” machine could change that. Also, the SS United States will join Florida’s 4,300 artificial reefs—human-made places for fish and other marine life to live. How do these reefs work?The Effort To Save Thousands Of Donor Kidneys From Being WastedSylvia Miles was diagnosed with lupus in 2006, a chronic autoimmune disease that causes the body’s immune system to attack healthy tissue—including her kidneys.Miles, who lives in Indianapolis, was later diagnosed with advanced kidney disease, and was in need of a kidney transplant.Kidney diseases are one of the leading causes of death in the United States with 37 million people living with chronic kidney disease. Together with advanced kidney disease—the later stage of CKD—it cost Medicare billions of dollars in recent years.People like Miles, who need a kidney transplant, wait an average of five years—often on dialysis.But despite the long waitlists and organ shortages, around 9,000 kidneys from deceased donors last year were discarded due to perceived issues with their viability. A new Indiana-based organization, 34 Lives, is working to limit that waste and rehabilitate the organs.Read the rest of this article on sciencefriday.com.Ocean Liner SS United States Will Become An Artificial ReefThis week, after a notable career, the SS United States, a 1950s ocean liner, took her sunset cruise. Like many retirees, the ship is heading south—from Philadelphia to Florida—where she’ll be reinventing herself. In this next chapter, the SS United States will have new passengers: fish and other marine creatures. The ship will be sunk to the bottom of the sea and turned into an artificial reef, joining more than 4,300 artificial reefs off the coast of Florida.Other sunken ships have become artificial reefs in the past, which have helped boost marine life as well as scuba diving and fishing tourism. Host Flora Lichtman speaks with Scott Jackson, a regional specialized agent with the Florida Sea Grant and University of Florida IFAS extension, about the science behind artificial reefs, and what has been learned from decades of research.Transcripts for each segment will be available after the show airs on sciencefriday.com.
