It’s been five years since the first laboratory-confirmed case of COVID-19 in the U.S., a bleak milestone in the early days of a pandemic that touched the lives of everyone. For the lucky ones, the virus mainly meant more precautions: mask-wearing, the occasional COVID test. But for others, a COVID-19 infection turned into long COVID . This is a chronic condition that lingers long after a COVID infection, and can reduce one’s ability to live their day-to-day life. It’s been estimated that about ...
Jan 28, 2025•18 min•Ep 953•Transcript available on Metacast A recent study in the journal Nature unveiled new proteins that can neutralize the deadliest of snake venoms. They’re “new” in that they aren’t found in nature—they were created in a lab, dreamed up by AI. Using AI to discover, or design, the building blocks of drugs is a fast-growing area of research. Another team of scientists out of Philadelphia is using AI to discover new antibiotics by resurrecting long-lost molecules from extinct species like neanderthals and woolly mammoths. We know what ...

Jan 24, 2025•24 min•Ep 952•Transcript available on Metacast Editors at scientific journals are quitting in droves. According to Retraction Watch , a watchdog publication, there have been at least 20 mass resignations since 2023. So, what’s going on? If you look closely, you’ll notice a common pattern—publishers are cutting back on the number of editors, increasing the number of papers, and charging hefty fees for authors to publish their work. The most recent mass resignation happened at the Journal of Human Evolution at the end of 2024. Both co-editors ...

The flashiest event of the season is also one of the easiest to see without binoculars or a telescope. A “parade of planets” —Venus, Saturn, Jupiter, and Mars—will be visible, and recognizable by their incredible brightness against the night sky. Uranus and Neptune will also be visible, but with a telescope. This string of planets will be visible for all of January. Additionally, the ATLAS ...

And, the decision for how to proceed with NASA's Mars Sample Return Mission will fall to the incoming administration. What Makes A Hula Hoop Stay Up? Hula hooping might appear to be a simple physical activity. But there’s some complex math and physics at play as the hoop goes around your body, and scientists haven’t had a clear understanding of those hidden forces—unt...

Jan 14, 2025•19 min•Ep 944•Transcript available on Metacast On January 6, the U.S. reported its first human death from the bird flu. According to the CDC, more than 60 people were diagnosed with bird flu in the US last year, up from just one case in 2022. If you look at global cases over the last two decades, of the nearly 900 reported cases in people, roughly half the patients died. H5N1 avian influenza has been circulating in birds—and even some mammals—for years. But in the spring of 2024, the virus turned up in dairy cattle . Since then, over 900 her...

From their crucial role in ecosystems as indicators of air quality to their stri...
Jan 09, 2025•31 min•Ep 941•Transcript available on Metacast You’re probably familiar with the concept of handedness—a glove made for your left hand looks basically like the one for your right hand, but won’t fit—it’s a mirror image. Many of life’s important molecules, including proteins and DNA, are chiral, meaning they can exist in either a left-handed or a right-handed form. But on Earth, nature only uses one version or the other in living organisms. Your proteins, for example, are all the left-handed version, while your DNA is all right-handed . With ...
