A rare meteorite that crashed through a New Jersey roof contains evidence of ancient salty fluids, organic compounds, and amino acids from a primitive asteroid. Its pristine chemistry could offer new clues about how space rocks helped supply early Earth with some of the ingredients needed for life.

The charity says plans for a new buyer fell through, meaning all the monkeys will be rehomed.

Scientists have generated quantum entanglement directly from sunlight, potentially offering a lower-energy alternative to the lasers normally used in quantum technology. Their outdoor experiment produced entangled photons with about 94% similarity to an ideal state. The result could pave the way for...

Blocking the glycine transporter SLC6A20 restored important brain signaling and improved social, communication, and repetitive behaviors in autism-related mouse models. The treatment also worked in human brain organoids and showed lasting effects in adult mice, suggesting the brain may remain more t...

Metal-rich asteroids could one day become hardware stores for Mars, supplying the materials needed to build and repair a growing colony. A new analysis shows that carefully selected asteroids may be reachable with current spacecraft technology. Some could even provide the ingredients for making rock...

Several enormous Megalodon vertebrae thought to have been destroyed in 1989 were found sitting unnoticed on a museum shelf. Their analysis strengthens evidence that the giant shark could exceed 24 meters (79 feet) in length and live for nearly a century. Researchers also estimate that its newborns m...

The bald eagle, who has gained worldwide fame as the protagonist of a nest live-stream in California, has been diagnosed with anemia.
