Nvidia’s lead in the AI chip race has made it the fourth most valuable company in the world.

AI image generators are getting faster, and cheaper to use.

Internet networking pioneer Cisco Systems is jettisoning more than 4,000 employees, joining the parade of technology companies in a trend that has helped boost their profits and stock prices while providing a sobering reminder of the job insecurity hanging over an industry increasingly embracing artificial intelligence.

A global registry tracking the flow of chips destined for AI supercomputers is one of the policy options highlighted by a major new report calling for regulation of "compute"—the hardware that underpins all AI—to help prevent artificial intelligence misuse and disasters.

A new insight into how leaves transform into slippery layers on railway lines, causing delays for passengers and costing the rail industry millions of pounds every year, has been revealed by engineers at the University of Sheffield.

Microsoft said Wednesday that U.S. adversaries—chiefly Iran and North Korea and to a lesser extent Russia and China—are beginning to use its generative artificial intelligence to mount or organize offensive cyber operations.

Lyft shares jumped 62% after the closing bell Tuesday thanks in part to a typo in the ride-hailing company's earnings release that appears to have sent investors' auto-trading algorithms—or "bots"—into a buying frenzy.

A team of researchers led by Center for Hybrid and Organic Solar Energy (CHOSE), Electronic Engineering Department at Tor Vergata University of Rome has developed the first air-stable lead (Pb) and tin (Sn)-free perovskite solar modules, fabricated with an antimony (Sb)-based perovskite-inspired material (PIM) as the light absorber. The results are published in the journal ACS Energy Letters.

Large language models (LLMs) are deep learning artificial intelligence programs, like OpenAI's ChatGPT. The capabilities of LLMs have developed into quite a wide range, from writing fluent essays, through coding to creative writing. Millions of people worldwide use LLMs, and it would not be an exaggeration to say these technologies are transforming work, education and society.

The excitement of auto racing comes from split-second decisions and daring passes by fearless drivers. Imagine that scene, but without the driver—the car alone, guided by the invisible hand of artificial intelligence. Can the rush of racing unfold without a driver steering the course? It turns out that it can.

Sam Altman, chief executive of ChatGPT-maker OpenAI, is reportedly trying to find up to US$7 trillion of investment to manufacture the enormous volumes of computer chips he believes the world needs to run artificial intelligence (AI) systems. Altman also recently said the world will need more energy in the AI-saturated future he envisions—so much more that some kind of technological breakthrough like nuclear fusion may be required.

Scientists have been trying to build snakelike, limbless robots for decades. These robots could come in handy in search-and-rescue situations, where they could navigate collapsed buildings to find and assist survivors.

Imagine heating your home from the ceiling, not from underfloor heating or radiators. Once installed like wallpaper, hi-tech infrared fabric emits heat in a similar way to the sun's rays. This could be a logical way to add low-carbon heat into existing homes that need retrofitting to improve energy efficiency.

General Motors is adding about 350,000 miles (563,000 kilometers) of roadways in the U.S and Canada to the area where drivers can use the company's "Super Cruise" partially automated driving system.

One of the features of 5G networks is so-called slicing, which is segmentation of the network. Physically, the network remains the same but is logically divided into slices depending on current requests. This approach guarantees a given level of signal quality. Resources are allocated dynamically to a specific segment: If some resources are not currently being used, they can be redirected to another segment.

Gotham City's Dark Knight boasts an impressive collection of technological marvels, but the superhero scientists at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) have cutting-edge capabilities of their own.

A nuclear power plant in Georgia has begun splitting atoms in the second of its two new reactors, Georgia Power said Wednesday, a key step toward providing carbon-free electricity.

Advanced AI systems are coming under increasing criticism for how much energy they use. But it's important to remember that AI could also contribute in various ways to our response to climate change.

Cybersecurity experts are warning that hospitals around the country are at risk for attacks like the one that is crippling operations at a premier Midwestern children's hospital, and that the U.S. government is doing too little prevent such breaches.

SINTEF researchers are applying methodologies used to transport oil and gas in their efforts to upscale a technology for carbon capture and storage. This is good news for the climate.
