Large language models (LLMs), the artificial intelligence systems underpinning the functioning of ChatGPT, Gemini and other similar conversational agents, are now widely used worldwide. In addition to processing, interpreting ...

The field of silicon photonics, which uses light rather than electricity to transmit and process data on semiconductor chips, has enabled optical systems to evolve from bulky setups to compact, advanced systems. Typically, ...

ChatGPT maker OpenAI said Thursday it would begin rolling out its newest and most powerful artificial intelligence (AI) model to select customers, saying it had built in safeguards to mitigate security risks.

Researchers at the University of Southampton have come up with a way to help people spot AI-generated faces. They've developed a short training program that improves people's ability to distinguish between real, human faces ...

Physicists from the University of Amsterdam have developed a method to print three-dimensional structures in ice. The researchers show how small pillars can be printed at an angle, making it possible to print arbitrary profiles ...

Producing hydrogen is essential for some of the world's biggest industrial and agricultural needs, but it also comes with a steep environmental cost: Most hydrogen made today is generated through processes that release large ...

While most believe artificial intelligence (AI) is changing science, researchers at the University of Notre Dame are exploring the reverse.

Plug-in hybrids have enjoyed a surge in popularity, but a study published Thursday showed they are polluting far more than most buyers think because they rely on batteries less often than regulators expected.

A new study finds that composite metal foam (CMF) could significantly improve automobile safety during frontal collisions. Using computational models to run detailed simulations, researchers found that incorporating CMF into ...

One drawback of most solar cells made with efficiency-boosting perovskite is the presence of hazardous lead in the materials that turn sunlight into electricity. Next-generation solar cells made with the most promising lead-free ...

A new AI framework can predict how fast an ambulance will move through city traffic, giving fire departments a way to test emergency response strategies in a virtual environment before making changes on real streets.

Electric vehicle maker Tesla announced the debut of its self-driving robotaxi, dubbed "Cybercab," on Thursday in a bid to compete with the likes of Uber and Waymo.
