Four engineering students were determined to find a way to help prevent sexual assault after seeing how deeply the crime had affected people close to them. Their solution was unlike anything they had worked on before: a clear fingernail polish designed to change color when it comes into contact with certain drugs that can be…
Scientists Just Found a Third Type of Magnetism, And It Could Change Electronics

For more than a century, physicists largely treated magnetism as a two-option system. Materials either had their tiny magnetic moments lined up like a conventional magnet, or those moments pointed in opposite directions and cancelled each other out. Then one stubborn piece of metal began behaving as though the rules had left something important out.…
Elon Musk Just Gave Workers a Blunt Warning About AI’s Next Move

For years, workers have been told that artificial intelligence could transform the way they earn a living. Some companies see AI as a tool that will remove repetitive tasks and allow employees to focus on more valuable work, while critics fear businesses will use the technology to replace people wherever possible. Now, after a meeting…
Scientists Program Bacteria To Consume Tumors From The Inside

A cancer treatment that sends microscopic organisms into a tumor sounds like something from a science-fiction movie, but researchers at the University of Waterloo are exploring a version of that idea in the laboratory. Their approach uses engineered bacteria that can grow inside the oxygen-starved center of solid tumors and potentially consume the nutrients there…
Atlantic Ocean Current Weakening Raises New Concerns For US Coastlines

A huge system of ocean circulation has been weakening for years, and scientists are watching closely for signs that the slowdown could become something much more serious. The concern stretches far beyond the North Atlantic, with research pointing to possible changes in weather, sea levels and coastal flooding. The biggest question is whether the Atlantic…
The Woman Behind NASA’s Next Giant Telescope Was Breaking Barriers Long Before Hubble Took Flight

A NASA telescope preparing to explore some of the biggest mysteries in the universe carries a name that deserves far more attention. Nancy Grace Roman helped shape American space astronomy from its earliest days, becoming NASA’s first chief astronomer and its first female executive. Long before the Hubble Space Telescope became one of the most…
