A user could ask ChatGPT to write a computer program or summarize an article, and the AI chatbot would likely be able to generate useful code or write a cogent synopsis. However, someone could also ask for instructions to build a bomb, and the chatbot might be able to provide those, too.

When scuba divers need to say "I'm okay" or "Shark!" to their dive partners, they use hand signals to communicate visually. But sometimes these movements are difficult to see.

Researchers at Linköping University, Sweden, have developed a digital display screen where the LEDs themselves react to touch, light, fingerprints and the user's pulse, among other things. Their results, published in Nature Electronics, could be the start of a whole new generation of displays for phones, computers and tablets.

The study focused on species of the Bacteroidales order, some of the most abundant species in the human gut microbiome.

It was a "bittersweet moment" as United Launch Alliance brought the Delta program to a close.

Vast amounts of worldwide emissions can be traced back to the supply chains that provide us with the goods we need. Some studies estimate that they generate up to two-thirds of global carbon emissions.

Smart textiles have the potential to revolutionize health care. In his doctoral thesis in textile technology, Emanuel Gunnarsson presents unique solutions to the bottleneck that has long inhibited the market.

Just as drivers in Brazil can be warned of traffic congestion ahead or a vehicle parked on the hard shoulder, notifications may soon pop up on their smartphone or on their car's computer screen to warn them in real time that an anteater, wolf or tapir is crossing the highway. No human will necessarily need to see the animal in question or press a control button to send the warning.

Deep learning is a form of artificial intelligence transforming society by teaching computers to process information using artificial neural networks that mimic the human brain. It is now used in facial recognition, self-driving cars and even in the playing of complex games like Go. In general, the success of deep learning has depended on using large datasets of labeled images for training purposes.

Research led by Hank Jenkins-Smith, Ph.D., director of the Institute for Public Policy Research and Analysis at the University of Oklahoma, explores American adults' perceptions of fusion energy. This first-of-its-kind study reveals broad public support from respondents, but their limited knowledge of the technology and frequent misconceptions could pose a challenge to those seeking to develop fusion energy in the U.S.

The concept of Waddington landscape, originally proposed by British developmental biologist Conrad Hal Waddington in 1957, has been influential in describing the dynamical evolution of cellular development.

Imagine a vast volume of porous sandstone reservoir, once full of oil and natural gas, now full of a different carbon-free fuel—hydrogen. Scientists at Sandia National Laboratories are using computer simulations and laboratory experiments to determine whether depleted oil and natural gas reservoirs can be used for storing this carbon-free fuel.

Study finds cancer-linked PFAS chemicals prevalent in drinking water sources across the globe, including many far over regulatory limits.

NASA flight engineers managed to photograph and videotape the moon's shadow on Earth about 260 miles below them.

Google’s chips also compete with Intel and Nvidia.

New chemistries for batteries, semiconductors and more could be easier to manufacture, thanks to a new approach to making chemically complex materials that researchers at the University of Michigan and Samsung's Advanced Materials Lab have demonstrated.

While cellular networks and Wi-Fi systems are more advanced than ever, they are also quickly reaching their bandwidth limits. Scientists know that in the near future they'll need to transition to much higher communication frequencies than what current systems rely on, but before that can happen there are a number of—quite literal—obstacles standing in the way.

A study led by Professor Sung-Kyun Jung and his research team in the School of Energy and Chemical Engineering at UNIST has unveiled a more stable approach to utilizing all-solid-state batteries (ASSBs), setting a new standard for the development of safe battery systems.

The 2024 solar eclipse fascinated millions across the U.S. — and those in the "path of totality" got to experience a few minutes of darkness during its daytime peak.

The next solar eclipses where parts of North America will experience totality won't be until 2044 and 2045.
