Mangos, often dismissed as too sugary, may hold hidden benefits for those at risk of diabetes. A George Mason University study found that daily mango eaters showed better blood sugar control and less body fat than those eating a lower-sugar snack. The results suggest that it’s not just sugar levels, but how the sugar is packaged in whole foods, that matters.
Read moreNot drinking enough water could intensify stress responses. Researchers found that under-hydrated individuals had cortisol levels more than 50% higher during stressful situations. Poor hydration didn’t make participants feel thirstier, but it did trigger biological signs of strain. Keeping a water bottle handy could help manage stress and safeguard health.
Read moreMeditation apps are revolutionizing mental health, providing easy access to mindfulness practices and new opportunities for scientific research. With the help of wearables and AI, these tools can now deliver personalized training tailored to individual needs.
Read moreWhy do some people stay protected after vaccination while others quickly lose immunity? Researchers in Japan tracked over 2,500 people for 18 months and found four distinct immune response patterns. The so-called “rapid-decliners” looked strong at first but lost antibodies quickly, leaving them more vulnerable to infection.
Read moreResearchers have identified 57 genetic variations of a gene strongly associated with declines in blood oxygen levels during sleep. Low oxygen levels during sleep are a clinical indicator of the severity of sleep apnea, a disorder that increases the risk of heart disease, dementia, and death.
Read moreNew research into the mechanics of cellular sleep and shutdown could shed light on the aging process and how to potentially intervene.
Read moreScience tells us that a lot of good things happen in our brains while we sleep — learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called microglia — which play an important role in reorganizing the connections between nerve cells, fighting infections, and repairing damage — are also primarily active while we sleep.
Read moreAn easy-to-use electrode set can assess sleep bruxism severity as well as a conventional polysomnography, a new study shows.
Read moreVirtual-reality researchers have developed a virtual-walking system that records a person's walking and re-plays it with vision and foot vibrations. Psychological experiments showed that the sensation of walking and telepresence from the oscillating visual flow combined with foot vibrations is stronger than without vibrations. The system can reconstruct the experience of walking to people who are a distance away, or who have a disability that may impair walking in the future.
