Four Students Had an Unusual Idea To Make Drinks Safer. Then Their Invention Took Off

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.…
More Singles Are Deciding They Like Life Without A Partner

For years, being single was treated like an unfinished chapter. Find someone, settle down, and move on to the next milestone. New research suggests a surprising number of Americans are no longer waiting for that chapter to begin. One in four single adults say they would stay single even if their “perfect match” appeared tomorrow,…
Scientists Found A Strange Signal Hidden Inside Living Cells

Something inside living cells appears to be producing a signal that researchers cannot easily explain with ordinary chemistry. A team in Shanghai detected an unusual oscillation at 71 terahertz in living human cells, mouse tissues and intact mitochondria, then found that the signal disappeared when the cellular structure was destroyed. The finding has reopened a…
The Three Albums People Turn To When Life Gets Hard

There is a strange moment after a breakup, a death, a career collapse, or one of those weeks when everything seems to go wrong. You open your music library and somehow end up playing the same album you heard during another terrible chapter years ago. For millions of listeners, three records have become especially powerful…
The Big Bang May Have Been A Cosmic Bounce After All

The universe may have had a beginning. Or it may have had a previous life that ended in a colossal collapse before bouncing back into the expanding cosmos we see today. A team of physicists has proposed a strange alternative to the standard picture of cosmic history: the event we call the Big Bang may…
Scientists Turned A Probiotic Into A Tiny Chemotherapy Factory

A bacterium commonly used as a probiotic has been genetically redesigned to manufacture chemotherapy inside tumors instead of sending the drug throughout the body. In experiments involving mice with colorectal cancer, the engineered bacteria helped three of seven treated tumors completely regress, while also triggering an immune response that affected cancer beyond the original treatment…
