Children with higher blood pressure as young as age 7 face a sharply increased risk of dying from cardiovascular disease by their mid-50s, according to a massive decades-long study. Researchers found that even moderately elevated...
Scientists have uncovered a surprising new healing mechanism in injured cells called cathartocytosis, in which cells "vomit" out their internal machinery to revert more quickly to a stem cell-like state. While this messy shortcut helps...
University of Minnesota researchers developed a 3D-printed scaffold that directs stem cells to grow into functioning nerve cells, successfully restoring movement in rats with severed spinal cords. This promising technique could transform...
Researchers identified over 400 genes tied to various forms of frailty, offering fresh insight into why people age differently. The study highlights six distinct pathways of unhealthy aging, opening the door to more precise, targeted...
Researchers discovered that early puberty or childbirth doubles women’s risk for major diseases and accelerates aging, while later timing offers protective benefits. Genetic analysis reveals evolutionary tradeoffs, where reproductive...
Many foods we consume today are ultraprocessed, packed with unhealthy ingredients, and linked to major health risks. As consumption of these foods rises, so do chronic health issues, especially among lower-income groups. Experts are...
Sunniva Kwapeng struggled with lipoedema, a painful condition causing disproportionate fat accumulation, until finally being diagnosed in her 40s. An NTNU study found that a low-carb diet helped alleviate pain and resulted in more weight...

In a groundbreaking UK first, eight healthy babies have been born using an IVF technique that includes DNA from three people—two parents and a female donor. The process, known as pronuclear transfer, was designed to prevent the...
Kids who consume artificial and natural sweeteners like aspartame, sucralose, and glycyrrhizin may face an increased risk of early puberty, especially if they carry specific genetic markers. This large-scale Taiwanese study links...
Midlife sleep habits may matter more than previously thought. A large study finds that poor sleep, alongside high blood pressure and nicotine use, sharply increases the risk of heart problems in menopausal women yet only 1 in 5 score...
A group of scientists studying pregnancy across six different mammals—from humans to marsupials—uncovered how certain cells at the mother-baby boundary have been working together for over 100 million years. By mapping gene activity in...
Researchers testing urine from 2- to 4-year-olds in four U.S. states uncovered 96 different chemicals, many of them unmonitored and linked to hormone and brain disruption. Legacy toxins like triclosan are slowly declining, yet...
Teen vaping is changing fast — and not in a good way. A large national study found that more adolescents are vaping THC, CBD, and especially synthetic cannabinoids, which are often unregulated and far more dangerous. Even more troubling,...
Teens are being misled by cannabis edibles dressed up like health foods. Bright colors, fruit imagery, and words like vegan make these products look fun, natural, and safe even when they re not. A WSU study warns that this could increase...
Teens are diving into intense skincare routines inspired by TikTok, often slathering on six or more products daily, sometimes over ten in just minutes, chasing beauty ideals that favor lighter, flawless skin. But new research warns this...
A new study suggests that boys who become overweight in their early teens risk damaging the genes of their future children, increasing their chances of developing asthma, obesity and low lung function.
Researchers reviewed US national fatal crash data (2016-2021) and examined the vehicle age and driver assistance technologies of vehicles driven by teen and middle-aged drivers, and their associations with driver deaths during fatal...
A study sheds light on when and how bacterial strains emerge on facial skin. The findings could lead to new treatments for acne and other conditions, and may also help optimize the timing of such treatments.
