Science Friday

The Trump administration has proposed cutting NASA’s budget by almost 25% and shutting down 19 currently operating science missions. On July 21, several hundred current and former employees of the space agency released an official letter of dissent, titled “The Voyager Declaration,” arguing against “rapid and wasteful changes which have undermined our mission.” Retired NASA astronaut Cady Coleman joins Host Flora Lichtman to explai...

Menopause is having a moment. Celebrities like Halle Berry, Naomi Watts, and Michelle Obama have recently shared their personal menopause experiences. Menopause and perimenopause are showing up across social media and even in popular books. All this to say, menopause has finally gone mainstream. 

But, it wasn’t until about three decades ago that menopause research really kicked into gear. Since then, scientists have made a lot of pr...

The EPA recently announced that it’s going to shut down its scientific research arm, called the Office of Research and Development. Since the agency was founded nearly 55 years ago, it’s had in-house scientists researching things like pollutants in our air and water, and the risks posed by toxic chemicals. That research informs the EPA’s guidelines and standards.

Host Flora Lichtman talks with Jennifer Orme-Zavaleta, who spent 40 ye...

In December, the Parker Solar Probe made history when it made the closest-ever approach to the sun by a spacecraft. As it whizzed by, a camera recorded incredibly detailed images, which show the sun’s surface, the flow of solar winds, and eruptions of magnetized balls of gas. Seeing this activity in such detail could help scientists understand solar weather.

Host Flora Lichtman talks with Parker Solar Probe project scientist Nour Ra...

You can’t get a mortgage without home insurance. But in some parts of the country, it’s becoming harder and harder to find a plan, as insurance companies drop homeowners  and pull out of entire states, as flooding, wildfires, and storms become more frequent and intense. Host Flora Lichtman talks to reporters Jessica Meszaros and Rachel Cohen, who have been covering this issue in Florida and Colorado. Flora then speaks with Benjamin...

Gen Alpha slang can seem unintelligible to adults, but linguist and TikToker Adam Aleksic argues language development in the internet age is worth legitimate study. Adam talks to Host Flora Lichtman about how algorithms and social media are changing the way we speak, and discusses his new book, Algospeak: How Social Media is Transforming the Future of Language.

Guest:
Adam Aleksic is a linguist and content creator, and the author of ...

The New World screwworm has cattle ranchers, entomologists, and the federal government on edge. The pest was successfully eradicated from the US decades ago, but has recently been moving north from South America into Central America and Mexico, with concerns that it may cross the border into Texas. It’s notorious for laying eggs in the wounds of animals and slowly eating them from the inside out. Host Flora Lichtman speaks with ent...

In July 1925, the Scopes “Monkey” Trial captivated the nation. On its face, the case was relatively straightforward: A Tennessee biology teacher named John Scopes was accused of teaching human evolution to his students. At the time, that was against state law. Both sides enlisted the help of big name lawyers to represent them, and the case turned into a national spectacle. But, why has the legacy of the case persisted? And what can...

It’s shaping up to be one of the worst tick years yet, and concerns about Lyme disease—which is transmitted through the bites of some species—are high. Aside from a short-lived vaccine released in the late 1990s, people have not had the opportunity to get vaccinated against Lyme disease. But if our dogs can get vaccinated, why can’t we? Host Flora Lichtman speaks with immunologist and Lyme disease expert Linden Hu about the ongoing...

About 7% of veterans experience post-traumatic stress disorder (PTSD), and that number can be closer to 30% for those who have served in a war zone.  

But PTSD has been treated pretty much the same way since the disorder was first recognized roughly four decades ago: Patients are instructed to revisit their trauma until the memory no longer creates an emotional response. This process can be so harrowing that over half of veterans ar...

For decades, astronomers have been trying to nail down the value of the Hubble constant—a measure of how fast the universe is expanding. But some cosmologists say there’s evidence that the universe is expanding faster than physics can explain, and our current models of it might be broken. Hosts Flora Lichtman and Ira Flatow talk with Wendy Freedman and Dan Scolnic, two cosmologists with different takes on this constant controversy.

For decades, residents of the small city of Newburgh, New York, were unknowingly drinking water contaminated with toxic PFAS—also known as forever chemicals. The source turned out to be firefighting foam used on a nearby air base that had seeped into streams and creeks, and ultimately the city’s main drinking water reservoir.

Now, Newburgh is one of 10 sites that are part of a CDC-led study investigating the health effects of PFAS e...

Oceanographer Victoria Orphan’s dream was coming true. She was sitting in the Alvin submersible, on one of its deepest science dives ever. But the trip was anything but smooth sailing. Victoria takes us inside the sub, where her dream turns nightmarish as things start to go wrong, and Alvin pilot Nick O’Sadcia works frantically to troubleshoot. Oceanographer Shana Goffredi, who’s also Victoria’s wife, tells us about the tense scene...

Researchers found a new sea spider with a giant nose, leg cannons, and—most remarkably—a novel way of surviving in the lightless, freezing environment miles below the sea surface. These oceanic arthropods are powered by methane that seeps out of the ocean floor.

Biologist Shana Goffredi joins Host Flora Lichtman to tell us more about the discovery and explain how we’re connected to these little beasts.

Guest: Dr. Shana Goffredi is a ...

President Trump has said that he wants to phase out FEMA, the Federal Emergency Management Agency, and move responsibility for dealing with major disasters to the state level. Since its creation in 1979, the agency has played a key role in coordinating emergency response nationally. Host Ira Flatow talks with Samantha Montano, an emergency management specialist and author of Disasterology: Dispatches from the Frontlines of the Clim...

Most pasta is made from just two ingredients—flour and water. For decades this humble food has prompted physicists around the world to try to understand its mysterious properties and answer questions like: Why does a stick of spaghetti break into three pieces and not cleanly into two? And why is cacio e pepe so hard to perfect? The answers reveal more about the building blocks of the universe than you might expect. Host Ira Flatow ...

We live in a world filled with microbes—they’re inside our bodies, in soil, in deep sea hydrothermal vents, and in your window AC unit. Some microbiologists are hopeful that finding more of these tiny organisms could help us address the climate crisis. Joining Host Flora Lichtman to talk about how are microbiologists James Henriksen and Lisa Stein.

GLP-1 medications like Ozempic have dominated headlines over the past couple of years. When writing his new book, Diet, Drugs and Dopamine: The New Science of Achieving a Healthy Weight, former FDA commissioner David Kessler wanted to unpack the science beyond those headlines. He also has a personal relationship with the subject, having taken GLP-1 medications himself. Host Flora Lichtman joins Kessler to talk about the latest scie...

In both her life and her work, researcher Karmella Haynes has never followed the pack. Karmella explains why she created her own area of research at the intersection of synthetic biology and epigenetics. Emory colleague David Katz weighs in on the challenges Karmella faces in pioneering a new research field. Plus Karmella’s sister Sherrone Wallace fills us in on their family life, and how their father raised them to inhabit spaces ...
