Scientists have created the first artificial tongue that can sense and identify flavors entirely in liquid environments — mimicking how human taste buds work. The achievement, described July 15 in the journal PNAS, could lead to automated systems for food safety and early detection of diseases via chemical analysis, the researchers say. The technology could … Read more
NASA is accelerating its plans for a nuclear reactor on the moon. For several years now, the agency has been working to get a 40-kilowatt fission system ready for launch to the moon by the early 2030s. But interim NASA chief Sean Duffy is about to announce a more ambitious path, via a directive set … Read more
Continents have lost so much water since 2002 that they have surpassed ice sheets as the biggest contributor to global sea level rise, a new study reveals. Almost 70% of this loss is due to unchecked groundwater extraction, which removes water from deep aquifers and eventually transfers it to the ocean, researchers found. Together with … Read more
Both Salvador Dalí and Thomas Edison are said to have used dreams to stoke their creative process. To spark new ideas, the men would let themselves drift off to sleep for just a few moments, and then wake up and note the dreamlike visions they had on the brink of unconsciousness. But you may have … Read more
Engineers have designed a spacecraft that could take up to 2,400 people on a one-way trip to Alpha Centauri, the star system closest to our own. The craft, called Chrysalis, could make the 25 trillion mile (40 trillion kilometer) journey in around 400 years, the engineers say in their project brief, meaning many of its … Read more
In 2024, Scottish futurist David Wood was part of an informal roundtable discussion at an artificial intelligence (AI) conference in Panama, when the conversation veered to how we can avoid the most disastrous AI futures. His sarcastic answer was far from reassuring. First, we would need to amass the entire body of AI research ever … Read more
DNA that humans acquired from ancient viruses plays a key role in switching parts of our genetic code on and off, a new study has found. Nearly half of the human genome consists of segments called transposable elements (TEs), also known as “jumping genes” because they can hop around the genome. Some of these TEs … Read more
The energy needed for thunderstorms could come from an avalanche of electrons seeded by extraterrestrial cosmic rays, a new study claims. Scientists already knew that lightning is an electrical discharge between thunderclouds and Earth’s surface, but exactly how storm clouds obtain an electric field powerful enough to hurl a bolt has remained a mystery for … Read more
A universal cancer vaccine in development could help rev up the immune system against tumors and supercharge the effects of existing cancer therapies, an animal study suggests. Similar to vaccines for viral infections like the flu, many cancer vaccines are designed to help the immune system recognize specific proteins. However, while conventional vaccines aim to … Read more
Google has harnessed motion sensors on more than 2 billion smartphones to create an earthquake early-warning system that’s as effective as standard seismometers, a new study reveals. Between 2021 and 2024, the company’s Android Earthquake Alerts (AEA) system captured more than 11,000 quakes through smartphone accelerometers and issued more than 1,200 alerts to Android users … Read more
