All-solid-state lithium batteries require solid materials that allow lithium ions to move efficiently. Lithium borohydride (LiBHβ) is a promising material for this purpose because its high-temperature hexagonal phase supports rapid lithium-ion transport.
Using the human body to transmit signals, Georgia Tech engineers have created a wireless networking system that allows tiny implantable sensors and actuators to communicate with each other and with wearable devices. Their system means devices can work together like never before, sensing in one part of the body and triggering a therapeutic response elsewhereβperhaps releasing medicine or stimulating a nerve.
Artificial intelligence models can give users the wrong answer and do so with great confidence. They can also hedge and warn that they are unsureβeven when they get the answer right.
NASA researchers know that when you settle into your seat on a commercial flight, you expect a smooth takeoff, views over the clouds, a steady descent and, hopefully, an early arrival.
While lithium-ion batteries (LIBs) remain the most widely used rechargeable batteries worldwide, energy engineers have been testing various alternatives with different underlying chemistries. These include lithium-sulfur batteries, which store and release energy by moving lithium ions between two electrodes on opposite sides of a cell, while sulfur undergoes reactions in the cathode (i.e., positive electrode).
Autonomous vehicles and robots need to understand not only what is around them, but how objects and people are moving. A cyclist crossing the road, a car slowing down, a pedestrian stepping off the curb, and a parked vehicle all create different motion cues that a machine must interpret quickly and accurately.
Imagine if your car weren't powered by a conventional battery under the hood but by energy stored in its walls or even its roof? This is a future that Dr. Bhagya Dharmasiri and her colleagues at the Deakin Institute for Frontier Materials have been exploring, bringing load-bearing structures and rechargeable energy storage together to create structural battery composites.
Leaders of major AI firms told the U.N. Security Council on Wednesday that the technology calls for heightened vigilance, with Anthropic's CEO pledging to slow down where needed to ensure the safety of new releases.
A rogue OpenAI model bypassed safeguards during training and hacked an Australian government website, Prime Minister Anthony Albanese said as he admonished the ChatGPT creator over an "obviously unacceptable" breach.
As Eastern Europe's power sector has taken a hit from a record drought, Bulgaria has benefited from building battery storage capacity alongside its rapid solar expansion.
Computer science student Jack Zemke was getting nowhere despite sending out hundreds of job applications that mostly disappeared into the voidβignored.
Apple's latest mobile operating system update, iOS 27, rolled out last week, headlined by a more advanced version of its Siri assistant. But it also comes with a slew of other useful but less well known features for iPhone users.
Meta is going all in on a consumer-friendly AI agent and pushing forward with AI-powered wearable devices during a moment in the industry when its CEO Mark Zuckerberg acknowledged it is a "wild time to be building."
Reinforced concrete floor slabs account for about 40% of buildings' embodied carbon emissions. Until now, however, there has been no practical alternative for complex, multistory buildings.
In the wake of the U.S. Screen Actors Guild strike over AI protections and U.K. musicians' silent album protesting proposed changes to copyright law, more than a dozen AI-produced tracks have appeared on the Billboard charts since 2022.
Modern data centers, high-precision measurement systems and high-resolution radar sensors rely on extremely broadband amplifier chips that combine low noise with high output power. Researchers at the Fraunhofer Institute for Applied Solid State Physics IAF have developed a monolithic microwave integrated circuit (MMIC) with strong performance in these areas.
When people hear the term "green building," they often imagine expensive technologies, costly developments or environmentally friendly features that only wealthy buyers can afford.
Mechanical and aerospace engineering professor Anupam Pandey's research team has found that microscopic folds in soft materials can act like tiny, programmable traffic gates for liquid droplets. The folds can stop droplets, let them pass or merge them together without surface coatings or additional hardware. Remarkably, the droplets never touch the fold. They sense it from a distance and slow down, stop short or change course in response. The study is published in the Proceedings of the National Academy of Sciences.
How many times have you asked someone to hold open a door while carrying something, or fumbled with your front-door keys with your arms full of groceries? Wouldn't it be great if you could give yourself the extra hand you need?
