Rejoice, amateur and professional astronomers: This January is a fantastic time for looking up at the sky. 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 sk…

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 tim…

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 in…

For years, artificial intelligence companies have heralded the coming of artificial general intelligence, or AGI. OpenAI, which makes the chatbot ChatGPT, has said that their founding goal was to build AGI that “benefits all of humanity” and “gives everyone incredible new capabilities.” Google DeepMind cofounder Dr. Demis Hassabis has described AGI…

Scientists investigated how the shape of the human body makes hula hooping possible—and what hips and a waist have to do with it. 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’…

Alcohol poses many risks to our health, including liver damage and driving under the influence. Now, U.S. Surgeon General Dr. Vivek Murthy has highlighted another risk of drinking alcohol: cancer. In his latest advisory, Murthy detailed the growing body of research showing that drinking alcohol can increase the risk of at least seven types of cance…

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 ha…

After her SciFri internship 20 years ago, Flora went on to become a beloved science journalist, video producer, and podcaster. Now she’s back! Also, several different fires are causing extreme damage in the Los Angeles area. Strong Santa Ana winds are one factor behind their rapid spread. Science Friday Now Has Two Hosts: Meet Flora Lichtman! Big n…

Last October, Ira Flatow took a trip to the World Forestry Center in Portland, Oregon, for a daylong exploration of lichen—the fuzzy growths often found on trees, roofs, and gravestones. Ira sat down in front of a sold-out room with Dr. Hannah Prather, postdoctoral researcher and visiting assistant professor of biology at Reed College, and Dr. Jess…

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…

Each year, the journalists at the MIT Technology Review publish a list of 10 breakthrough technologies: these are things poised to hit a tipping point, and potentially change the way the world works. Unsurprisingly, artificial intelligence remains a big breakthrough. While 2024 was the year of large learning models, small learning models top Techno…

This winter marks the 125th year of Audubon’s Christmas Bird Count, in which bird nerds across the Western Hemisphere venture outside to record all the birds they see and hear. Scientists use that data to understand how birds are faring, where they’re moving, and what they’re up to when it’s not breeding season. With 125 years under its belt, the C…
