OpenAI, maker of ChatGPT, on Monday took the first step toward going public, one week after rival Anthropic announced its own filing, as both companies look to raise the massive sums needed to expand.

Quantum materials, materials with properties that are governed by the laws of quantum mechanics describing many-body interactions, have proved promising for the development of various advanced technologies. Many of these ...

Typically, the information encoded in DNA allows organisms to develop, function, and pass traits across generations. Yet DNA alone does not explain how genes are switched on and off in different cells and environments. This ...

Bryozoans are tiny, filter-feeding colonial invertebrates that thrive in the world's oceans today, yet for decades their origins presented a puzzling gap in the fossil record. While nearly every other major animal group made ...

Astronomers have investigated a puzzling binary star system in which two stars that may have formed together now show dramatically different chemical compositions. The new study, uploaded to the arXiv preprint server on May ...

By borrowing a trick from tiny jumping spiders, Northwestern University engineers have developed an extremely energy-efficient 3D camera. Called SpiderCam, the new device senses depth the same way that jumping spiders judge ...

Astronomers have spent over a decade tracking a unique type of compact dwarf galaxy, which continues to surprise everyone. Known as the "Little Red Dots" for their small, red appearance, these local galaxies look much like ...

Researchers from Tokyo Metropolitan University have used simulations to show that a newly developed, compact X-ray telescope could be used to map the chemical composition of the entire lunar surface, a vital breakthrough ...

Imagine a train parked at the station. Passengers climb aboard and find their seats. Conductors move up and down the aisles, checking tickets. But there's a problem—the engineer's watch is broken. As a result, the doors never ...
