Scientists have found a new way to tweak tiny lasers so they can emit light at different colors and stay super focused. Imagine a laser that can change its color smoothly while staying sharp and strong—that's what these micro lasers now do. They used a trick with changing chemicals inside the laser
The human brain is wrapped in a tight shield called the blood-brain barrier. Its job is to block harmful stuff while letting in water and nutrients. When this barrier leaks even a little, the brain can get hurt. Scientists want to measure how fast water moves in and out—not to crack the door open, b
When a rocket explodes during testing, the damage isn’t just physical—it ripples through schedules, contracts, and rivalries. Blue Origin’s New Glenn rocket suffered just such a fate, leaving its launch pad in pieces and its future plans in limbo. The incident happened during a routine test fire, a
Russia is scrambling to get its hands on advanced technology from the West, not just to keep its military running but to stay relevant in the long run. With sanctions squeezing its economy and years of war draining resources, Moscow is turning to spies, fake companies, and cyberattacks to steal what
Helping people regain their ability to walk after an injury isn’t easy. Traditional rehabilitation can be slow, and some patients struggle to regain full movement. A new kind of robotic suit might change that. This lightweight exoskeleton helps patients relearn how to walk by gently guiding their le
This week, tech stocks hit all-time highs, but some are now pushing into risky territory. Micron, a chipmaker for AI gadgets, saw its stock jump nearly 30%, pushing it into "overbought" levels. That’s fancy talk for "maybe it’s too expensive right now. " The surge came after UBS boosted its price ta
Remember that old phone gathering dust in your drawer? It might end up doing more than just taking photos. Scientists have found a clever way to give these devices a second life as environmental guardians. Instead of tossing them, researchers turn them into eco-friendly sensors that track how trees
In a chilly March night near the Rio Grande Gorge, two teens were saved by a buzzing machine instead of a helicopter. The drone’s infrared camera spotted them before the cold set in, and rescuers acted fast from a command center. The success shows how drones can cut down wait times for help, giving
An artist in Brooklyn has turned her studio into a living laboratory, where tiny organisms and flying robots mingle to ask big questions about life. Her work shows how bacteria can paint, perfume, and even build ecosystems that grow on their own. In a park in New York’s Hudson Valley she set up colu
Walmart is cutting the price of a robotic pool cleaner by $151, making it an affordable choice for families who want to keep their pools tidy. The WYBOT Cordless Robotic Pool Cleaner is now listed at $88, down from its original $240 tag. The device works in both above‑ground and in‑ground pools, han
