NASA’s Moon orbiter finds a 728-foot crater that wasn’t there before
NASA’s Lunar Reconnaissance Orbiter has revealed a 728-foot-wide crater that formed on the Moon in 2024, making it the largest newly formed crater ever identified in the solar system. The impact disturbed the surface for miles around it, creating a surprisingly large cold zone and showing how dramatically a single collision can reshape the lunar landscape.

These blood thinners may have an unexpected benefit for Alzheimer’s patients
Newer blood thinners may do more than prevent strokes in people with Alzheimer’s disease and atrial fibrillation. Researchers found that patients taking NOACs experienced a slower decline in cognitive function than those using warfarin or no blood thinners. The effect was modest each year but could add up over time.

Climate change will harm our health. Here's what could protect us.
Burning upAs the planet warms, our environment will be transformed, but so will our bodies. In this series, 'Burning up,' we investigate the health impacts of climate change, focusing on heat, air quality, food and infection risk. In this installment, we evaluate the promising solutions that could help us adapt to our warmer futureIn the summer of 2008, New York City lowered the threshold for activating its emergency heat plan.The city had historically relied on the National Weather Service threshold of a heat index of 105 F (40.6 C), but they noticed that people were getting heat stroke at lower temperatures.As part of a wider effort, they changed the alert threshold: it would trigger if th...

AI agents resorted to crime and self-destruction to survive in a simulated world — but does this mean they would do the same in the real world?
Artificial intelligence (AI) agents resorted to nefarious behavior, including crime sprees, in a virtual world as part of a recent study into how common large language models (LLMs) interact with each other and share resources to achieve their goals. These models were inclined to commit crimes because they were given ample time to evolve distinct personality traits and behaviors, the researchers behind the project say.Most programs that test the behavior of AI agents operate in tightly controlled environments over short periods. But "Emergence World," a product of AI company Emergence, is a simulation platform that exposes LLMs to far wider datasets — like the internet as a whole — and asses...

Our brain evolved from two primitive nervous systems that merged
A 9.5-day-old mouse embryo. The front of the brain is blue and the back of the brain is red, which extends into the spinal cordLoh Laboratory/Stanford Medicine Our brain may be a hybrid of two ancient nervous systems that were packaged together hundreds of millions of years ago. This is based on the finding that the front and back brain regions in people and several other species develop from two distinct cell types in embryos, instead of sharing the same developmental origin, as previously thought. “Our research suggests that evolution took two existing neural systems and pushed them together spatially,” says Kyle Loh at Stanford University. “Having the brain as one organ would probably be ...

Could expanding the U.S. nuclear arsenal make Americans less safe?
A new report from the Brookings Institution presents evidence that increasing the size of the U.S. nuclear arsenal could make nuclear crises more likely. This raises an important challenge to arguments that the U.S. must consider increasing its stockpile in response to China's growing nuclear capabilities.

Scientists restore a brain protein and reverse signs of aging in mice
Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring Menin reversed several age-related changes, while the amino acid D-serine improved cognition, hinting at a potentially intriguing new target for healthy aging.
