The world’s largest explosion lab is ready for big booms. And yes, it’s in Texas.

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent six days a week. Everything is bigger in Texas, and that includes its controlled detonations. Texas A&M University recently revealed what they say is the world’s largest controlled explosion lab, where researchers can fill a nearly 500-foot metal tube with gas and ignite it in the name of science. They are calling it The Detonation Research Test Facility (DRTF). By precisely measuring what it takes to turn a simple flame into a massive, deadly detonation, researchers hope to make discoveries that could better prepare engineers to prevent gas leaks, and potentially inform ways to build explosion-resistant infrastructure. And all of that will require lots and lots of yeehaw inducing bangs. Located in Southeast Central Texas, the detonation tunnel is about six feet in diameter and stretches nearly the length of two football fields. Its metal exterior consists of three-quarter-inch steel walls and is covered in earth to muffle the sound—or try to, at least. Inside, the tube holds various sensors that can measure …

On Africa trip, Pope Leo will face debate over polygamy as Catholicism booms

On Africa trip, Pope Leo will face debate over polygamy as Catholicism booms

VATICAN CITY — This week, Pope Leo XIV will walk in the footsteps of his icon, Saint Augustine of Hippo, a towering theologian whose birth in what is now Algeria makes him history’s most revered African Catholic. In strife-ridden Cameroon and authoritarian Equatorial Guinea, Leo will flex his powers as peacemaker and diplomat. In oil-rich Angola, he will confront a microcosm of the global tussle between Catholicism and evangelical faiths. Source link

Secondhand market booms, challenging luxury industry

Secondhand market booms, challenging luxury industry

Despite its astronomical price, the Kelly bag by Hermès has found a buyer. In December 2025, at the height of the Christmas rush, LuxSpace sold a gold leather model of the bag for €27,980. It was a secondhand item. Located in Paris’s 8th arrondissement at 90 Rue du Faubourg Saint-Honoré, the boutique specializes in pre-owned luxury goods. Its founders, Zhao Xiujun and her husband, Wang Goan, chose the address for its proximity to the historic Hermès store, which draws crowds year-round at number 24. LuxSpace offers more than 600 models, including the most expensive from Hermès, Louis Vuitton, Dior and Chanel. Most of the pieces cost several thousand euros. “If it’s in good condition, the Chanel 2.55 can be worth €7,000 to €8,000,” explained Qian Siu, who oversees consignments. That’s 30% less than the retail price. Secondhand luxury bags, each costing around €30,000. Inside the LuxSpace store in Paris, January 14, 2026. SIMONE PEROLARI FOR LE MONDE  The highly select consignment shop caters to buyers who are purchasing luxury goods for the first time, “tourists …

Sonic booms offer new way to track falling space debris

Sonic booms offer new way to track falling space debris

Sonic booms are no longer just associated with supersonic jets or rocket launches as scientists are now using sonic booms to help solve a rapidly escalating problem: tracking space debris as it reenters Earth’s atmosphere. Over the past decade, the number of defunct satellites, spent rocket stages, and fragmented spacecraft circling the planet has surged. This boom in orbital activity has led to a sharp rise in uncontrolled reentries, where objects plunge back to Earth without precise guidance or prediction. These events pose mounting risks to people, infrastructure, and the environment, particularly as more complex spacecraft carrying hazardous materials are sent into orbit. Predicting exactly when and where debris will fall remains a major challenge. Traditional monitoring systems, such as radar and optical tracking, often lose track of objects as they burn up in the atmosphere. As fragments break apart and scatter, accurate tracking becomes even more difficult, complicating emergency response and recovery efforts. Why is space debris so dangerous? Space debris refers to any non-functional, human-made object orbiting Earth. This includes defunct satellites, abandoned …

Study Shows How Earthquake Monitors Can Track Space Junk Through Sonic Booms

Study Shows How Earthquake Monitors Can Track Space Junk Through Sonic Booms

Scientists reported Thursday that seismic readings from sonic booms that were generated when a discarded module from a Chinese crew capsule reentered over Southern California in 2024 allowed them to place the object’s path nearly 20 miles (30 kilometers) farther south than radar had predicted from orbit. Using this method to track uncontrolled objects plummeting at supersonic speeds, they said, could help recovery teams reach any surviving pieces more quickly — crucial if the debris is dangerous. “The problem at the moment is we can track stuff very well in space,” said Johns Hopkins University’s Benjamin Fernando, the lead researcher. “But once it gets to the point that it’s actually breaking up in the atmosphere, it becomes very difficult to track.” His team’s findings, published in the journal Science, focus on just one debris event. But the researchers already have used publicly available data from seismic networks to track a few dozen other reentries, including debris from three failed SpaceX Starship test flights in Texas. A growing concern among scientists and others is that falling …
