Skin accounts for around 15 percent of your body mass. It is the largest and most visible organ in the human body. Yet many of the skin’s functions are often overlooked. It’s a sunscreen, a shield from germs, a reservoir of vitamin D, and a means of tightly regulating our body temperature. Being the most ...
From the bristles of brushes to the porous surfaces of sponges, your makeup kit can harbor a host of bacteria and fungi. These potentially hazardous contaminants can originate not only from the cosmetics themselves, but also from the very surface of our skin. So, how can we keep things hygienic and avoid microbial growth on ...
About 400,000 years after the Big Bang, the cosmos was a very dark place. The glow of the universe’s explosive birth had cooled, and space was filled with dense gas — mostly hydrogen — with no sources of light. Slowly, over hundreds of millions of years, the gas was drawn into clumps by gravity, and ...
The morning started with a message from a friend: “I used your photos to train my local version of Midjourney. I hope you don’t mind,” followed up with generated pictures of me wearing a flirty steampunk costume. I did, in fact, mind. I felt violated. Wouldn’t you? I bet Taylor Swift did when deepfakes of ...
As the world rushes to make use of the latest wave of AI technologies, one piece of high-tech hardware has become a surprisingly hot commodity: the graphics processing unit, or GPU. A top-of-the-line GPU can sell for tens of thousands of dollars, and leading manufacturer NVIDIA has seen its market valuation soar past US$2 trillion ...
For decades, psychology departments worldwide have studied human behavior in darkened laboratories that restrict natural movements, such as walking. Our new study, published in Nature Communications, challenges the wisdom of this approach. Using virtual reality (VR), we have revealed previously hidden aspects of perception that occur during a simple everyday action — walking. We found ...

It’s unthinkable that a modern Boeing 777-200ER jetliner with 239 people on board can simply vanish without any explanation. Yet multiple searches in the past decade have ...
In the few short years since the COVID pandemic changed our world, China, Japan, and India have all successfully landed on the Moon. Many more robotic missions have flown past the Moon, entered lunar orbit, or crashed into it in the past five years. This includes spacecraft developed by South Korea, the United Arab Emirates, ...
You may be used to hearing that it takes the Earth 365 days to make a full lap, but that journey actually lasts about 365 and a quarter days. Leap years help keep the 12-month calendar matched with Earth’s movement around the Sun. After four years, those leftover hours add up to a whole day. ...
Over half the adult population in the UK and U.S. have gum disease from poor oral health. Typical treatments include mouthwash and, in severe cases, antibiotics. These treatments have side effects, such as dry mouth, the development of antimicrobial resistance, and increased blood pressure. Research has indicated that a molecule called nitrate, which is found ...
