The obesity headlines that matter, in one email every morning. Free.
A surprising study of more than 4,500 older adults found that people who were overweight or obese when diagnosed with dementia had a 16% to 27% lower risk of death than those at a normal weight. Researchers suspect that extra energy and muscle reserves may help patients survive t
Scientists have discovered that tumors release natural antioxidants to shut down the immune cells responsible for destroying cancer, exploiting a surprising weakness in the body's defenses. Blocking this mechanism in mice restored immune activity and improved immunotherapy respon
After more than 35 years of research, scientists have uncovered surprising clues about what really drives Lyme disease risk. Contrary to longstanding assumptions, deer populations appear less important than mice, which can fuel a 40% increase in tick numbers the following year. E
Scientists have discovered that a buildup of a protein called Miro1 may be a hidden driver of insulin resistance in Type 2 diabetes, with preclinical experiments showing that removing it restores the muscles’ response to insulin. Exercise was also found to lower Miro1 levels in p
MIT scientists have developed nanoparticles that reprogram immune cells directly inside the body to attack cancer and harmful immune cells, eliminating tumors and reversing liver damage in mouse experiments. The breakthrough could make powerful immune therapies dramatically simpl
A surprising new study suggests that an anti-aging drug could help protect people genetically predisposed to Alzheimer's disease. Researchers found that just four weeks of low-dose rapamycin improved brain blood flow in healthy middle-aged adults carrying the high-risk APOE4 gene
Scientists have developed a revolutionary gel that could regrow lost tooth enamel by harnessing minerals naturally found in saliva, potentially overcoming one of dentistry’s biggest limitations. The regenerated enamel behaves much like healthy enamel, raising hopes for a simple t
A new study suggests that ultra-processed foods may influence children's developing brains in ways that encourage weight gain. Researchers from USC studied 46 children ages 7 to 10 and found that those who ate more ultra-processed foods showed stronger activity in the brain's rew
A major 24-year study involving more than 8,200 adults suggests that excess body weight may accelerate brain aging, leading to faster declines in memory, concentration, and decision-making skills. The connection was particularly strong among people over 65, raising concerns about
In a surprising discovery, scientists found that certain diets associated with obesity can make cancer immunotherapy more effective in mice, challenging traditional assumptions about diet and cancer treatment. The findings suggest that the secret may lie in how food interacts wit
A UCLA study found that long-term exposure to a common pesticide was linked to more than 2.5 times the risk of Parkinson's disease. Scientists also uncovered how the chemical damages brain cells and identified a promising way to protect them.
Scientists have discovered a bizarre bacterial defense system that works almost completely backward from anything seen before. Unlike typical bacterial immune systems that keep a deadly toxin under control until a virus attacks, this unusual mechanism waits until an infection beg
A surprising study of more than 4,500 older adults found that people who were overweight or obese when diagnosed with dementia had a 16% to 27% lower risk of death than those at a normal weight. Researchers suspect that extra energy and muscle reserves may help patients survive t

A new study found that energy drinks and stimulant supplements were linked to disproportionately frequent reports of serious heart problems, including 11 times more reports of cardiac arrest and 4.5 times more reports of heart attacks. Young adults accounted for nearly half of th
Ancient manuscripts, including the 1,000-year-old York Gospels, have revealed traces of a deadly sheep virus whose history stretches back more than 3,700 years. Scientists discovered that the virus has remained remarkably unchanged for millennia, turning historic parchment into a
A surprising new weapon against microbes linked to head and neck cancer could be as simple as chewing gum. Scientists developed a bioengineered gum that reduced HPV levels by up to 93% in oral samples from cancer patients and nearly eliminated two harmful bacterial species after
New research involving more than 440,000 Americans links cannabis use to increased cardiovascular risk, with occasional users showing 40% higher odds of reporting a history of stroke. The findings suggest that even infrequent marijuana use may warrant concern, although researcher
A major review of more than 350 studies suggests that eating less protein could slow aging, improve metabolic health, and potentially extend lifespan, challenging the widespread belief that more protein is always better. Researchers warn that many sedentary adults may be consumin
Scientists have discovered that tumors release natural antioxidants to shut down the immune cells responsible for destroying cancer, exploiting a surprising weakness in the body's defenses. Blocking this mechanism in mice restored immune activity and improved immunotherapy respon
Even when bad cholesterol is brought down to healthy levels, some people remain at risk of heart attacks, and scientists may have discovered why. Researchers identified two types of fat-carrying particles that appear to promote inflammation and damage blood vessels through mechan
A surprising discovery suggests that some early signs of Alzheimer’s disease may begin outside the brain. Using miniature laboratory systems made from human cells, scientists found that genetic mutations associated with inherited Alzheimer’s can disrupt nerve-to-muscle connection
Scientists have discovered that pantethine, a readily available vitamin B5 derivative, can calm overactive immune cells and may help fight psoriasis. The supplement prevented psoriasis in mice and showed promising results in a small human trial, revealing an unexpected connection
Scientists have discovered that gut bacteria can feed on the protective mucus lining your intestines, producing potentially harmful compounds, but fiber helps keep this activity in check. Overlooked proteins in plant foods also help shift gut bacteria toward producing beneficial
