Astronomers have released more than three million new spectra in a sweeping expansion that, for the first time, brings SDSS-V optical observations to the Southern Hemisphere. The data reveal everything from rare stars and glowing nebulae to hundreds ...

Researchers have discovered that a gene linked to congenital heart disease acts like an architect for the heart cell's DNA. Losing just one copy of TBX5 can cause the genome's carefully folded 3D structure to unravel, disrupting the genes needed to . ...

NASA's Perseverance rover caught a striking first from Mars: Earth disappearing behind the tiny moon Phobos. Seen from nearly 195 million miles away, our planet was reduced to a single point of light before briefly vanishing behind Phobos. The rare . ...

Astronomers using the James Webb Space Telescope have discovered a bizarre object from just a few hundred million years after the Big Bang that looks like an enormous star but shines far too brightly to actually be one. The mysterious red object, ...

Scientists may have uncovered evidence that a mammal ancestor was giving birth to live young 236 million years ago. A fossilized cynodont showed a neonatal growth line and an unusually large birth size that closely match patterns seen in modern ...

A protein inside appetite-controlling brain cells may play an important role in preventing overeating and obesity, particularly when high-fat foods are readily available. Unexpected differences between males and females could also help explain why .. ...

A single human brain cell may be far more powerful than scientists once realized. Researchers found that cortical neurons can perform remarkably complex computations, giving them capabilities more like tiny biological computers than simple on-off ...

Why do we keep making the same choices even when better options are available? Researchers found that simply repeating a decision can reshape what we prefer, causing familiar choices to feel better than alternatives. Instead of weighing every option ...

AI has helped scientists measure the brain's hidden cleaning system, revealing that fluid moves rapidly around its outer spaces but about 50 times more slowly through deep tissue. The discovery could eventually help researchers detect circulation ...

Ozempic-like drugs appear to weaken more than hunger--they may also reduce cravings for alcohol and other addictive substances. Scientists are increasingly tracing this effect to the lateral septum, a brain region that helps connect memories and ...
