Dehydration can sneak up on you. Whether you’re out jogging or sitting at a desk, it’s easy to lose track of your fluid intake. But a new, tiny sweat sensor may soon solve this problem. Designed by UC Berkeley researchers, this wearable device can measure changes in your hydration status and help you decide when it’s time to take a break and get some water.

In a study recently published in Nature Electronics, researchers demonstrated how their sweat sensor measures electrodermal activity (EDA), an electrical property of the , to monitor hydration levels during physical activity. Until now, EDA, or skin conductance, has been thought to be effective at assessing only mental stress.

These findings could broaden EDA’s role in physiological monitoring and someday provide a simple way for people to also avoid dehydration.

Living to 100 may sound like a dream, but thanks to advancements in anti-aging and longevity research, it’s becoming more of a realistic goal than ever before. While genetics play a role, experts say your daily habits have a major impact on how gracefully—and healthfully—you age. From diet and movement to mindset and skincare, there are key lifestyle shifts and science-backed secrets that can help slow the aging process, boost vitality, and support a longer, more vibrant life.

Robert Love, a neuroscientist, shared three anti-aging and longevity secrets you should know about if you want to “slow down aging” and “even help reverse aging.” According to him, prioritizing sleep, avoiding ultra-processed foods, and taking healthy supplements are some of the best options. Read on to learn more.

Prioritizing sleep is one of the most powerful (and underrated) anti-aging tools you have. During deep sleep, your body goes into repair mode—producing growth hormone, regenerating cells, and fixing damage caused by stress and environmental factors. This nightly “reset” helps keep your skin, organs, and even brain functioning optimally.

Scientists have discovered a new four-body quasi-particle, the quadruplon, in a 2D semiconductor. Using laser experiments and advanced theory, they identified unique spectral features unexplained by existing models, confirming the quadruplon’s existence. A central goal of physics is to understand

Determining the passage of time in our world of ticking clocks and oscillating pendulums is a simple case of counting the seconds between ‘then’ and ‘now’

Down at the quantum scale of buzzing electrons, however, ‘then’ can’t always be anticipated. Worse still, ‘now’ often blurs into a haze of vagueness. A stopwatch simply isn’t going to work for some scenarios.

A potential solution could be found in the very shape of the quantum fog itself, according to a 2022 study by researchers from Uppsala University in Sweden.
