A dying star could create a new universe instead of a black hole

What if some black holes aren’t black holes at all? A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon. Instead, the collapse could trigger the birth of a tiny new universe inside the dying star. Driven by dark energy, this miniature cosmos would expand and push back against gravity, preventing complete collapse and…

Alien planet spins revealed a hidden clue to how worlds form

Using the Keck Observatory, astronomers measured the spins of dozens of giant planets and brown dwarfs orbiting distant stars. They found that giant planets can spin faster than much more massive brown dwarfs, challenging simple assumptions about mass and rotation. The results suggest that magnetic fields and formation processes play a major role in determining how fast worlds end up spinning.

How can we make buildings more resilient before—and after—earthquakes? We put one solution to the test

This week's magnitude 7.8 earthquake in the Philippines came with scenes familiar to New Zealanders: collapsed buildings, shattered facades and streets strewn with rubble.

Battery-free artificial photosynthesis keeps solar fuel production stable under shifting sunlight

Researchers at Osaka Metropolitan University have developed an artificial photosynthesis system capable of producing solar fuels more stably by integrating a self-regulating chemical component directly into the electrolyzer itself. The new device doesn't rely on a battery-powered control method, removing an expensive component of such systems. The study is published in EES Solar.

Dark energy survives major challenge as universe keeps accelerating

A bold claim that the universe’s accelerating expansion was an illusion has been put to the test—and failed. Researchers found that the study behind the controversy made key mistakes when analyzing supernova data. After revisiting the evidence, astronomers concluded that cosmic acceleration remains as strong as ever.

Google researchers introduce 'faithful uncertainty,' allowing LLMs to offer best guesses instead of hallucinations

Large language models continue to struggle with hallucinations, presenting a major roadblock for real-world enterprise applications. Reducing these errors is a messy business, forcing model developers to navigate a strict tradeoff where eliminating factual errors often suppresses valid answers. In a new paper , Google researchers introduce the concept of "faithful uncertainty," a metacognitive…

80 Texas residents are suing SpaceX, saying rocket launches are literally destroying their homes

Eighty residents of towns near SpaceX’s Starbase facility in South Texas have filed a class-action lawsuit alleging that the company’s constant rocket launches are physically destroying their homes. The lawsuit accuses SpaceX of negligence, gross negligence, and trespass based on the Commercial Space Launch Act of 1984. One plaintiff showed Reuters her home in Port […] This story continues at The…

New strategy enhances oxygen reduction in zinc-air batteries

Batteries are undergoing rapid advances. For example, modern zinc-air batteries have the remarkable ability to use oxygen as energy—but that oxygen isn't stored in the battery itself. Zinc-air batteries take in surrounding oxygen to undergo a reaction to discharge energy called the oxygen reduction reaction (ORR). While this convenient strategy is promising, the slow speed of the ORR limits the…
