Moxie Marlinspike, the mind behind Signal, has announced a partnership with Meta to weave his AI privacy tech into the company’s new chatbot. The move aims to make sure that conversations stay private even when powered by artificial intelligence. The new AI, called Confer, is already built on a fou
After menopause, many women notice changes in their body that go beyond hot flashes. Research on mice shows these changes could link to a hormone-like substance called asprosin. After removing ovaries to mimic menopause in mice, scientists found that asprosin levels jumped higher in blood and fat ti
"Bamboo is famous for tasty shoots, but what makes their outer sheaths look so different? Scientists studied five types of a popular bamboo called Chimonobambusa utilis. Each type was named C1 through C5, and researchers measured how bright or dull each sheath looked. One variety, C1, had a very lig
Pharmacy learners often think they know how well they will do on tests, but their guesses are usually too high. The problem is a lack of metacognitive awareness – the skill of checking one’s own understanding. When students overestimate, they also feel overly confident about their predictions.
A new device made from two layers of aluminum can change the way light twists, working well across a wide range of colors from green to near‑infrared. The designers did not use an idealized flat coating; instead they measured the real, uneven shape of a silica (SiO₂) layer that sits on top of the
Scientists are turning to a special imaging trick that makes the normally invisible flow of energy inside cells visible. By feeding cells a version of pyruvate that glows brighter than usual, researchers can watch how it turns into lactate in real time. The key to understanding this process lies in
Meta has taken legal action against three groups that ran deceptive ads using celebrity images and deep‑fake technology. The lawsuits were filed in Brazil, China, and Vietnam against operators who lured users worldwide with false promises about investments and health products. The Brazilian cases
Many people who receive a liver transplant later develop metabolic syndrome, a mix of health problems that can shorten life. Doctors say exercise is key to keeping these patients healthy, but most do not stick with it. A research team used the COM‑B model to figure out why some patients move a
The new science shows that the best way to protect your mind as you age is to move enough, but not too much. Studies that followed older people for almost a decade found that those who walked between 5, 000 and 7, 500 steps each day had slower buildup of the tau protein that causes Alzheimer’s. E
When people try to shed pounds, a new idea catches attention: chill cooked starches before eating them. The concept is based on the science of two kinds of starch found in foods like rice, pasta and potatoes. One type, amylose, is hard for the body to break down quickly; the other, amylopectin, diss
