James Webb discovers a rare giant planet with surprisingly Earth-like temperatures
Astronomers have used the James Webb Space Telescope to characterize TOI-199b, a Saturn-sized gas giant over 330 light-years away that maintains surprisingly Earth-like temperatures despite its massive scale. The planet's methane-rich atmosphere makes it one of the first so-called "temperate" gas giants ever studied in meaningful detail. The discovery opens a new category of planetary science, offering a potential window into atmospheric dynamics that have no analog in our own solar system.

AI makes a major breakthrough in a math problem that had stumped experts for decades
Mathematicians have been unable to crack the planar unit distance problem since Paul ErdΕs first posed it in 1946 β until now. An AI system has delivered a breakthrough on the nearly 80-year-old geometry puzzle, marking a significant moment in machine-assisted mathematical discovery. The development signals a growing role for AI in tackling problems that have resisted the best human minds for generations.

βZombie cellsβ arenβt always bad and that could transform anti-aging medicine
Senescent "zombie" cells have long been cast as villains in the aging process, but new research suggests some actually play a protective role in the body. This nuanced understanding is forcing a rethink of broad-spectrum senolytic drugs, which indiscriminately clear aging cells and may do more harm than good. The next frontier in anti-aging medicine hinges on developing targeted therapies that eliminate only the damaging cells while leaving beneficial ones intact.

Overpopulation can impair fertility. A new study explains why
Decades of research have shown that overcrowding suppresses reproduction across species β from chickens laying fewer eggs to mice bearing smaller litters β but the underlying mechanism has remained elusive. A new study now offers a biological explanation for why population density directly impairs fertility. The findings could shed light on declining birth rates in densely populated human societies.

Hi-res microscopes give biologists petabytes of data. Scientists are creating an AI assistant to make sense of it
Modern microscopy has become a victim of its own success, generating petabytes of imaging data that far outpace researchers' ability to analyze it. Scientists at UC Berkeley are now developing AI tools trained on this firehose of high-resolution biological imagery to automate analysis and surface insights that would otherwise take years to extract manually. The effort could fundamentally accelerate how quickly biologists move from raw data to discovery.
