Largest Animal Crossing, First Complete Human Genome, Exoplanet Discoveries. November 25, 2022, Part 2

11/25/2022
Building The World’s Largest Animal Crossing Outside of LA There’s a spot on Highway 101 in Agoura Hills, it’s pretty inconspicuous. There’s brown and green rolling hills on either side of the highway. Homes are sprinkled here and there. And then a small metal gate that leads off on a hiking trail. You probably wouldn’t know it, but soon this spot will be the location of the world’s largest animal crossing. This crossing will reconnect habitats that have been cut off from each other for...

The Science Behind Your Favorite Thanksgiving Dishes Thanksgiving is right around the corner, and for many people, that means it’s time to start thinking about what will be on the menu for dinner that night. Many people will opt for a classic turkey: others, a vegetarian-focused meal. Regardless of the plan, preparing food for the holiday can take some planning, and there’s a lot of science that goes into it. Cookbook author Kenji López-Alt thinks about the science behind cooking a lot....

What Is The Metaverse, Missouri Groundwater Contamination, Eight Billion People On Earth. November 18, 2022, Part 1

11/18/2022
There Are Now Eight Billion People On Earth. What’s Next? Humankind just hit a big milestone this week: a world population of eight billion people. A hundred years ago, there were less than two billion, and now we’ve more than quadrupled that. But after decades of quick population growth, what will the next few decades hold? Sophie Bushwick, technology editor at Scientific American, explains this to Ira live from the studio. They also talk about other science news this week, like a new...

How Past Extinctions At The La Brea Tar Pit Can Teach Us About Our Climate Future If you drive through Los Angeles, you’ll pass by some of California’s most iconic sites—the Hollywood Walk of Fame, Universal Studios, the Santa Monica Pier. But if you don’t look for it, you may miss the La Brea tar pits—a place where Ice Age life from around 50 thousand years ago got trapped and preserved in sticky black ooze. Visitors can see megafauna, including skeletons of saber tooth cats and dire...

Contraceptive Failures, Future Of Combating Covid, Rapid Evolution In The Anthropocene. Nov 4, 2022, Part 1

11/4/2022
Why Contraceptive Failure Rates Matter In A Post-Roe America Birth control options have improved over the decades. Oral contraceptives are now safer, with fewer side effects. Intrauterine devices can prevent pregnancy 99.6% of the time. But no prescription drug or medical device works flawlessly, and people’s use of contraception is inexact. “No one walks into my office and says, ‘I plan on missing a pill,’” said obstetrician-gynecologist Dr. Mitchell Creinin. “There is no such thing as...

11/4/2022
Using Family Photos Of Fall Foliage To Track Climate Change Leaf-peeping, or tourism based on observing the colors of fall foliage, is a big industry in parts of the Northeast. So as leaves continue to change across the northern United States with the turning of the seasons, researchers are working to better understand how climate change may be affecting fall colors—changes that may affect the bottom line for those tourism-rich areas. But to tease out the factors involved with the timing of...

Why Do Cats Purr? An Investigation Into A Purr-fect Mystery Science Friday recently received a voicemail from a listener named Violet from Maui, Hawai’i, who wanted to know: Why do cats purr? We wanted to see what other cat lovers knew about cat purring. So we sent our talented SciFri colleagues Diana Montano and Kyle Marian Viterbo to the Meow Parlor, a cat cafe in New York City to find out. Guest host Katherine Wu, who recently wrote about why cats purr for The Atlantic, also talks with...

Don’t Trust What You See On TikTok This Election Season Midterm elections in the United States are just under two weeks away. And new research suggests a significant risk of misinformation for American social media users—particularly from the video-sharing platform TikTok.

10/21/2022
The Science Behind Why You Should Ask For Help Sometimes asking for help—even for the smallest of favors—can feel awkward, or like you’re inconveniencing someone else. But the odds are, you’re probably wrong. Studies show that people are much more willing to lend a helping hand than you would think, and both parties usually end up happier. Guest host Shahla Farzan talks with Dr. Xuan Zhao, a psychologist at Stanford University, about the psychology behind asking for help. A Possible...

Burying Green: Eco-Friendly Death Care On The Rise Dying, it turns out, isn’t carbon neutral. Like many of the choices we make in our lifetimes, the choice to cremate or preserve our bodies after death comes with tradeoffs as well. With preservation and burial, there’s the carbon cost of cemetery space, the materials to make a coffin, and the chemicals required to prevent decay. With cremation, the body’s carbon is released into the atmosphere through the burning of natural gas. This is...

Scientists Are Trying To Study Human Neurons… In Rat Brains? Scientists have a tricky time studying neurons, partially because they are remarkably difficult to grow in a lab. They need other cells around them, and they don’t replicate or reproduce like other cells do. In a new study in Nature, researchers figured out that they can take a ball of human brain tissue and frankenstein it into a rat’s brain, and the rat can respond to it. This exciting discovery could offer scientists a new way...

The Politics Of Science: Voters Have An Important Voice This November’s general election season covers every level of government, from Congress at the federal level, to state governors and local ballot initiatives. Also on the ballot are many issues where understanding science better might result in better policy—think zoning questions about building next to rising seas or fire-prone wildlands, or questions about drug legalization and abortion access. Even whether to invest in education...

Hurricane Ian Destroys Iconic Florida House Meant To Survive Hurricanes The Cape Romano Dome House, built in 1982, was an iconic—if more recently unsightly—piece of Florida architecture. The six interconnected domes located in Collier County, Florida, were built to be hurricane resistant and self-sustaining, with solar power, rainwater harvesting, and other innovations. However, erosion and rising sea levels had put the structure at risk, with the structure’s foundation pillars being...

Sperm Swim Together To Help Each Other Reach The Egg New research is complicating our understanding of how, exactly, sperm are able to reach eggs. The predominant theory is that sperm compete against each other, with the strongest swimmer fertilizing the egg. But a new study, using cow sperm, suggests that sperm might actually swim together, forming clusters to help each other swim upstream to reach the egg. Researchers created a device that has some of the features of a female...
