Scientists have found that Uranus is emitting its own internal heat — even more than it receives from sunlight — and this discovery contradicts observations of the distant gas giant made by NASA’s Voyager 2 probe nearly four decades ago. Scientists led by Xinyue Yang of the University of Houston analyzed decades of readings from … Read more
Scientists have created a prototype robot that can grow, heal and improve itself by integrating material from its environment or by “consuming” other robots. It’s a big step forward in developing robot autonomy, the researchers say. The researchers coined the term “robot metabolism” to describe the process that enables machinery to absorb and reuse parts … Read more
As many as 200 worlds beyond our solar system discovered by astronomers may be larger than estimated, which could influence the search for extraterrestrial life. That’s the theory of a team of researchers who looked at hundreds of extrasolar planets, or exoplanets, observed by NASA’s Transiting Exoplanet Survey Satellite (TESS). TESS hunts exoplanets by catching … Read more
An experimental, hormone-free male birth control pill has just passed its first safety test in humans. The trial included 16 people and was only intended to test whether the drug reached adequate levels in the body, as well as whether it triggered any serious side effects, such as concerning changes in heart rate, hormone function, … Read more
Mars was a rainier, wetter place than planetary scientists previously thought, according to a new study of ancient, inverted river channels that span more than 9,000 miles (14,484 kilometers) in the Red Planet’s southern Noachis Terra region. “Our work is a new piece of evidence that suggests that Mars was once a much more complex … Read more
Our solar system has been around for 4.6 billion years. While that sounds like a long time, it’s just a blip in the 13.8 billion-year story of the universe. And one day, the solar system will cease to exist. But when will the solar system end? And how will it die out? The answers to … Read more
More than 5,000 people have applied for a first-of-its-kind migration visa that offers residents of a Pacific island an escape from the worst effects of climate change. Applications for the visa opened to people in Tuvalu on June 16 and close today (July 18). Under its terms, 280 Tuvaluans can relocate to Australia each year … Read more
You can use up all the storage on your phone or max out your computer’s drive, but can you use up all the memory space in your brain? Despite how you might feel before an exam or after a sleepless night before a work deadline, neuroscientists say that for a typical, healthy brain, memory capacity … Read more
On a weekend in mid-May, a clandestine mathematical conclave convened. Thirty of the world’s most renowned mathematicians traveled to Berkeley, Calif., with some coming from as far away as the U.K. The group’s members faced off in a showdown with a “reasoning” chatbot that was tasked with solving problems they had devised to test its … Read more
Up to 3 in every 1,000 newborns has hearing loss in one or both ears. While cochlear implants offer remarkable hope for these children, it requires invasive surgery. These implants also cannot fully replicate the nuance of natural hearing. But recent research my colleagues and I conducted has shown that a form of gene therapy … Read more
