Bill Gates warned Wednesday that the world is dangerously unprepared for the upheaval brought by artificial intelligence, with the technology destroying jobs and threatening human connection, especially for young people.

A research team has developed a flexible near-infrared (NIR) photodetector that delivers photoresponsivity more than five times higher while maintaining its performance under repeated bending. The technology is expected to ...

A hiker is lost in the forest, and winter weather is setting in. The search needs to be speedy, thorough and efficient. Searchers send out an autonomous robotic drone. But how does it know where it should go? New research ...

Perovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the ...

Evaporation, the process by which water becomes vapor and disperses into the environment, draws heat from its surroundings. This heat, also known as atmospheric thermal energy, is abundant but diffuse, making it difficult ...

A Chinese humanoid robot set a new 100-meter sprint record of 8.86 seconds in Beijing on Tuesday, beating its robot competitors—and the fastest recorded human time.

Researchers at Princeton Engineering have created a semiconductor with unique properties: It is just a few molecules thick and can repeatedly change its properties in response to light. This is a step toward building more ...

Safety protections built into some of the world's most widely used artificial intelligence (AI) models can be stripped away with alarming ease, according to a new international study.

Researchers at the University of the Witwatersrand (Wits) and the University of Bordeaux in France have demonstrated a new way to send information through the atmosphere without correcting for the distortions that normally ...

Like past transformative technologies, from railroads and radio to the internet, artificial intelligence has attracted optimistic investors and inflated valuations, and with them speculation of a bubble market—when eager ...

Merchant ships, coastal infrastructure and maritime facilities are often built with iron and steel, which can corrode over time despite their strength, eventually to the point of failure. With lives and goods on the line, ...

Hydrogen gas (H₂) is widely regarded as a promising clean energy source. By weight, it stores nearly three times more energy than gasoline, and its use does not directly release carbon dioxide (CO₂). Yet most H₂ is still ...
