Today’s Pulse rundown
El Niño in PNG
Transcript: What if the weather suddenly shifted and froze your entire summer garden? Families across the Highlands of Papua New Guinea are facing severe drought and frost. The National Weather Service says the El Niño weather pattern is shifting rainfall away and reducing moisture levels. The lack of cloud cover allows heat to escape rapidly at night, causing temperatures to drop below freezing. This sudden frost is destroying crops like potatoes that up to three million people rely on for food and income. How would you protect your plants from a sudden overnight freeze?
Chewing Sounds AI
Transcript: Can you guess what someone is eating just by listening to them chew? Scientists at Florida Atlantic University trained an artificial intelligence model to identify exactly what marine predators are eating. They recorded the underwater sounds of whitespotted eagle rays crushing shells off the Florida coast. The AI can tell the difference between prey because snails take less time to eat than clams. Snails have just one point of attachment to their shell, so they break open much faster! Next time you eat a loud, crunchy snack, think about what your chewing sounds like!
NASA's Lucy Asteroid
Transcript: What if you found a giant space rock shaped exactly like a peanut? NASA just released data from the Lucy mission showing that asteroid Donaldjohanson is a wobbling, bilobate rock. The spacecraft flew within six hundred and fifty miles of it back in April 2025. The asteroid spins end-over-end once every ten point five Earth days. The YORP effect alters the asteroid's rotation because sunlight warms the uneven surface and releases infrared radiation, creating a tiny recoil force that twists it. If you could name a newly discovered asteroid, what would you call it?
Strangler Fig Toilets
Transcript: Did you know that wild animals in the rainforest share a public restroom? Researchers from the University of Connecticut discovered that strangler fig trees in Costa Rica serve as treetop toilets. They caught seventeen different mammal species using the trees! The trees have a flat platform up to thirty-nine inches wide where the branches join. Sloths might use the tree latrine because it is risky to poop on the ground, or because the dirt-covered platform seems enough like the ground to them. What is the strangest animal behavior you have ever heard of?
Scouts AI Badges
Transcript: What if you could earn a scout badge for mastering artificial intelligence? The Explorer Scouts are launching exciting new badges focused on content creation and online safety. The group consulted nearly three thousand teenagers to design the updated program. Instead of just learning how to build campfires, fourteen to eighteen-year-olds will learn how to navigate the modern digital world. The badges teach young people how to investigate digital footprints and design resources to help others manage online risks safely. If you could invent a brand-new scout badge, what modern skill would it test?
TESS Super-Puff Planets
Transcript: Imagine visiting a giant alien planet that is as light and fluffy as cotton candy! NASA just announced that the TESS mission discovered two super-puff planets orbiting a star one thousand one hundred and thirteen light years away. Scientists calculated the planets' masses by using the variation in orbital timing caused when the planets tug on each other gravitationally. They found that the larger planet contains just five point nine percent of Jupiter's mass, making it incredibly light! If you could travel to a cotton candy planet, who would you take with you?
RAISE US AI Nonprofit
Transcript: How do we make sure robots do not take over everyone's jobs? A new bipartisan nonprofit called RAISE US is working to prepare workers for the rise of artificial intelligence. They are launching pilot programs in Arkansas, Maryland, Utah, and Connecticut. The group wants to help companies adopt new technology without leaving American workers behind. They are teaming up with major businesses to create new training programs so people can learn the skills needed for the future economy. What kind of job do you think will be most important in the future?
Katy Perry 'Watch It Burn'
Transcript: Are you ready for a fiery new pop anthem? Katy Perry just released a brand-new pop-rock song called Watch It Burn on Thursday night. The cinematic music video features her wreaking havoc as a monstrous scorpion-human hybrid! The singer says the powerful song is about reclaiming her life and finally putting herself first. She even performed the track live for fans at a massive music festival in Spain before it was officially released to the world. What is your absolute favorite song to listen to when you need a burst of energy?

How Earthquakes Shake the Ground
Transcript: Did you know that massive earthquakes can sometimes happen in pairs? The U.S. Geological Survey says the back-to-back earthquakes that struck Venezuela on Wednesday evening were a rare event known as a doublet. A seven point two magnitude quake hit first, followed by a seven point five just thirty-nine seconds later! Doublet earthquakes happen when a pair of similar-sized quakes hit close in location and time. The quakes were unleashed by a rupture where the Caribbean and South American tectonic plates meet. Have you ever felt the ground shake during an earthquake?
