A world-first, non-invasive AI system can turn silent thoughts into text while only requiring users to wear a snug-fitting cap. The Australian researchers who developed the technology, called DeWave, tested the process using data from more than two dozen subjects. Participants read silently while wearing a cap that recorded their brain waves via electroencephalogram (EEG)

Google on Wednesday infused its Bard chatbot with a new-generation artificial intelligence model called Gemini, which it touts as being able to reason better than ChatGPT and other rivals. The search engine juggernaut is aiming to take the generative AI lead from ChatGPT-maker OpenAI as that company deals with the aftermath of a boardroom coup

ChatGPT was launched on 30 November 2022, ushering in what many have called artificial intelligence’s breakout year. Within days of its release, ChatGPT went viral. Screenshots of conversations snowballed across social media, and the use of ChatGPT skyrocketed to an extent that seems to have surprised even its maker, OpenAI. By January, ChatGPT was seeing

For the first time, artificial intelligence (AI) has searched for, detected, confirmed, classified, and announced a supernova discovery without any human intervention. An international team of scientists developed a new AI tool called Bright Transient Survey Bot (BTSbot), using over 1.4 million images from nearly 16,000 sources to train its machine-learning algorithm. Northwestern University reports

In the world of lithium-ion batteries, smartphones take centre stage. Yet they’ve also sparked an ongoing debate: does prolonged (or overnight) charging wreak havoc on your battery? A number of factors determine a phone battery’s lifespan, including its manufacturing age and its chemical age. The latter refers to the battery’s gradual degradation due to variables

Wi-Fi signals can do much more than deliver streaming movies and music around the home, it turns out: they can also be used to identify shapes through solid walls, as demonstrated in recent experiments. The ability for Wi-Fi to spot movement through walls has been shown off before, but the technology struggles with seeing anything

Ever since 1911, when British mycologist Michael Cressé Potter noticed that brewer’s yeast generated electricity, scientists have been trying to harness the power of microbial fuel cells. But the efficiencies of tiny, budding ‘bioreactors’ have been too low for practical use. What’s more, it turns out microbes can be surprisingly picky in what substrates they

In an effort to create robots capable of controlling their own life-cycles, researchers have developed squishy little devices that can melt themselves into a puddle of goo. “We have mimicked death in a life cycle where the robot could end itself,” Seoul National University engineer Min-Ha Oh told Peter Grad at Tech Xplore. This ‘death’
