As Black Friday approaches, you’re probably being inundated with ads for bigger, better televisions. But just how good is good enough? Are there limits to what our eyes can even make out? Visual perception researcher Maliha Ashraf joins Host Flora Lichtman to describe her new study on display resolution—including a display calculator she and her co…

Decades ago, non-native carp were brought onto fish farms on the Mississippi River to control algae and parasites. They escaped, thrived, and eventually flooded the Illinois River, outcompeting native species and wreaking havoc. If the carp find their way into the Great Lakes, they could do major damage to those vital ecosystems. There’s a proposed…

Axolotls are one of the most charismatic and beloved amphibians out there. But did you know that there’s only one place in the whole world where you can find them in the wild? It’s Lake Xochimilco in Mexico City. There, scientists are scrambling to save them from extinction by creating refuges, using environmental DNA to track them down, and tag-te…

Endometriosis is a painful disease that occurs when endometrium-like tissue grows outside of the uterus. It’s extremely common—if you have a uterus, you have a 1 in 10 chance of getting it. Yet, it takes seven years on average to receive a formal diagnosis. What does the latest science tell us about the biology of the condition and how to treat it?…

We've figured out how to harness renewable energy from many natural systems, like solar, wind, and geothermal power. But what about the ocean’s waves? It might seem like converting wave power into electricity on a large scale would’ve been figured out by now, but the tech is actually just getting its sea legs. Why has it been so hard to develop? An…

For Halloween, we bring you an ode to three quintessentially creepy creatures: bats, arachnids, and snakes. First, bat researcher Elena Tena joins Host Flora Lichtman to describe tracking the greater noctule bat in flight and learning that it can feed on migratory birds. Then, arachnologist Paula Cushing describes the camel spider, which is neither…

There’s an established playbook for getting one’s affairs in order before death—create a will, name legal guardians, and so on. But there’s also a newer consideration: what will happen to our digital presences, like social media accounts, files, photos, videos, and more. So how do we manage them, and make sure we’re not turned into AI chatbots with…

At first blush, the plots of many horror movies don’t seem particularly appealing. Take “The Shining”: A murderous psychopath tries to kill his family in a haunted, secluded hotel. But horror movies have had devoted fans for as long as they’ve been around, and lately, scary movies and television shows like “Sinners” or “The Walking Dead” have made …

For decades, peanut allergies were on the rise in the US. But a study released on October 20 found that peanut allergies in babies and young children are now decreasing. This drop correlates with a change in guidance from the National Institute of Allergy and Infectious Diseases. In 2017, the agency started recommending exposing children to peanuts…

Bacteria have been around for billions of years. Could they have come up with complex behaviors that we just don’t understand yet? Could they have their own language? Their own culture? Their own complex societies playing out right under, and in, our noses? Microbiologist Bonnie Bassler has been studying these questions for more than 30 years. She …

After years of development, lab-grown fish is taste-test ready for the public. Four restaurants in the US are serving up cultivated salmon made by the company Wildtype. Producer Kathleen Davis gives Host Flora Lichtman a rundown on how Wildtype tastes, initial public perception, and the upstream battle to take cultivated meat mainstream. Plus, SciF…

Do science documentaries need a refresh? What if the goal wasn’t just teaching you something, but making you feel something? A new series from the BBC, airing on PBS, called “Human” tries to do just that. It tells the tale of our ancient family tree, embracing the complex and dramatic sides of the story. It asks: Who were the different species of h…

TikTok and other social media sites are full of mental health content—often short, grabby, first-person videos detailing symptoms for conditions like ADHD and autism. But what does this mean for teens and young adults who spend hours a day scrolling? A new study published in PLOS One analyzes the 100 most viewed TikTok videos about ADHD to assess b…
