Today’s Pulse rundown
France Fires
Transcript: What if you had only five minutes to escape a wall of flames? Tens of thousands of people have evacuated their homes as massive wildfires merge across France and Spain. French President Emmanuel Macron asked the European Union for help as the emergency strains local resources. Scientists say human-driven climate change is increasing the intensity of heatwaves and droughts. The high temperatures are even warming French rivers used to cool nuclear reactors, causing them to reduce output to protect the environment. How can communities better prepare for extreme summer heat?
Upside-Down Whales
Transcript: Have you ever seen a giant whale floating completely upside-down? Researchers from the University of Western Australia noticed that southern right whale mothers sometimes rest belly-up in the water. The scientists believe mothers float upside-down because they need a break from their nursing calves. By keeping their bellies above the surface, mothers periodically restrict access to their milk to conserve energy. They lose around a quarter of their body weight while raising their young! What is your favorite way to recharge when you feel exhausted?
Natural Ozempic
Transcript: Imagine discovering a powerful new medicine hidden inside your own body! Stanford Medicine researchers used artificial intelligence to find a natural peptide called BRP. In mice, it suppresses appetite and reduces body weight without common side effects. The molecule acts specifically in the hypothalamus, a small brain region that controls appetite. Because it targets this specific area, it influences hunger without producing as many effects elsewhere in the body. The algorithm was absolutely key to sorting through thousands of proteins. How else could AI help doctors discover new treatments?
Graduation Outfits
Transcript: How much would you spend to look perfect for a single photograph? University students in the UK are finding creative ways to manage the high costs of graduation outfits. With official photos costing up to three hundred and fifty pounds, students are feeling the pressure. What this means for you: To save money, graduates are thrifting dresses on apps like Depop, renting gowns, or asking family members to tailor custom suits. It is a smart way to celebrate a major milestone without breaking the bank. Would you rather buy an outfit or design your own?
AI for Tasks
Transcript: If a robot lifts weights for you at the gym, do your muscles get any stronger? A professor at the Harvard Kennedy School says students should not use artificial intelligence to write their policy memos. What this means for you: He argues that the struggle of writing helps develop critical thinking skills because the act includes thinking, outlining, drafting, and editing. If you skip that uncomfortable process, those mental skills will slowly fade away. The initial discomfort is a normal and healthy stage of learning. When is it okay to use AI for your homework?
Moon Rocks
Transcript: What if a rock could tell you exactly what happened billions of years ago? Scientists at the Guangzhou Institute of Geochemistry are analyzing ancient samples collected by the Chang'e-6 mission from the moon's far side. The far side preserves a cleaner record of asteroid impacts because it was much less affected by later geological events than the side facing Earth. The rocks reveal that early asteroid impacts declined gradually rather than happening in one catastrophic burst. This helps us understand the conditions experienced by the young Earth. What secrets do you think are hiding on the moon?
Ocular Prosthetics
Transcript: What if your medical device doubled as a dazzling piece of art? In Portland, Oregon, ocularist Christina Leitzel is crafting custom prosthetic eyes that feature sparkling night skies, gold irises, and even cat eyes! Most eye prosthetics have two parts, including a surgically implanted sphere. Tissue grows into the porous implant, helping the prosthetic move with the wearer's natural eye. While half of her work matches the real thing, Leitzel's fun designs help clients express their personalities and heal from trauma. If you could design a custom artistic eye, what pattern would you choose?
The Strokes
Transcript: How does a famous rock band keep their sound fresh? The New York City rock band The Strokes just released their seventh album, called Reality Awaits. What this means for you: The album successfully blends frontman Julian Casablancas's experimental side projects with the band's classic pop minimalism. Fans are thrilled to hear the group exploring playful new melodies and energetic grooves. Taking creative risks can lead to a long career. Who is your favorite band to listen to for an energy boost?
Lanterns Trailer
Transcript: Are you ready to patrol the galaxy with a magical ring of green light? HBO just released a new trailer for Lanterns, an upcoming eight-episode DC Studios series premiering on August 16. What this means for you: The show stars Kyle Chandler as Hal Jordan and Aaron Pierre as John Stewart. The heroes use magical rings that allow them to create any object imaginable out of green light. They travel to Nebraska to investigate a mysterious murder involving shape-shifting aliens called Manhunters. If you had a Green Lantern ring, what is the first object you would create?
Overnight Deliveries
Transcript: Have you ever wondered who stays awake so your package arrives by breakfast? In South Korea, shoppers are guaranteed delivery by seven in the morning for orders placed before midnight. What this means for you: This convenience is possible thanks to a huge overnight workforce. However, the industry is facing scrutiny after forty-six warehouse and delivery workers died from suspected overwork. While some drivers prefer the night shifts for the higher pay, families are demanding better safety rules. Would you be willing to wait longer for a package if it helped workers stay safe?
