A new study reported by Science Daily finds that tiny air pollution particles from smoke, soot, and dust may worsen rheumatoid arthritis and trigger painful flares. Prolonged exposure appears to raise the risk the most.
According to Science Daily, a long-term brain study has identified four common, changeable health risks strongly linked to vascular dementia: smoking, high blood pressure, heart disease, and high blood lipids. Researchers say managing these risks together could reduce several types of brain damage at once.
According to the Guardian, an analysis of vapes confiscated from schoolchildren found many contained not cannabis but the synthetic cannabinoid known as spice. Experts warn parents may be misidentifying what their children are using — and that spice carries far greater risks.
A new study reported by STAT News finds that a Covid-19 infection can reawaken other viruses that have lain dormant in the body for years. The finding could help explain some of the lingering symptoms associated with long Covid.
According to the BBC, researchers have found a way to keep vaccines stable at room temperature for up to a year. The breakthrough could transform global immunization by eliminating the cold-chain failures that cause vast numbers of doses to be wasted every year.
Scientists have successfully created 16 viruses whose genetic code was designed entirely by artificial intelligence, according to the BBC. The bacteria-targeting viruses mark a milestone for AI in biology — and have reopened a debate about how such tools should be controlled.
Researchers found that a chewing gum formulated with specific compounds reduced oral HPV viral load by up to 93% in some study participants. The early-stage findings raise hope for a low-cost tool against a virus linked to a rising share of head and neck cancers.
New research suggests posture does more than protect the back — sitting upright appears to influence mood, stress response and even decision-making speed. Scientists behind the study explain what the body-mind link reveals about everyday posture habits.
A new long-term study has found that three modifiable health factors in midlife can delay the average onset of dementia by roughly 13 years. Researchers stress that addressing these factors in a person's 40s and 50s, rather than later in life, produces a substantially larger protective effect.
Researchers are testing whether transplanting gut bacteria from healthy donors can retrain the immune systems of children with severe food allergies, starting with peanut allergy. Early-stage trials show promise, but scientists caution that questions about safety, mechanism and durability remain unresolved.
The FDA has approved Moderna's mFlusiva, the first influenza vaccine built on mRNA technology, following the platform's rapid rollout during the Covid-19 pandemic. Researchers say the approval could reshape how quickly flu vaccines are updated each season and how effective they become.
Jet lag disrupts the body's internal clock when travelers cross several time zones quickly. Sleep scientists say adjusting light exposure, meal timing and sleep schedules before and during a trip can meaningfully shorten recovery. Here is what the research actually recommends.
Losing weight is not simply a test of willpower: the human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal. This biological 'memory' triggers stronger hunger, cravings and lower energy use after weight loss, helping explain why many people regain weight after dieting. It also explains why medications such as Wegovy and Mounjaro can help by dampening appetite signals, though their effects may fade once treatment stops.
The Ebola virus has killed more than 1,700 people in eastern Democratic Republic of Congo, in what STAT News describes as the fastest-growing outbreak of the disease on record. The virus spreads through direct contact with the bodily fluids of infected people or animals, and DRC has recorded more Ebola outbreaks than any other country since 1976. Health officials say accelerating vaccine access and expanding treatment capacity are now the most urgent priorities.
The US Centers for Disease Control and Prevention has reportedly expanded its investigation into the largest known cyclosporiasis outbreak to 15 states, according to a Washington Post report citing three people familiar with the matter. The expansion followed Michigan's health department reporting the first two US deaths linked to the outbreak. Cyclospora cayetanensis, the parasite behind the illness, typically spreads through contaminated fresh produce and causes watery diarrhea that can last for weeks.
Running has surged in popularity in recent years, but for anyone with joint pain or simply no love of pounding pavement, low-impact cardio options can deliver comparable benefits. Swimming, cycling, rowing, elliptical training and water aerobics all raise the heart rate without the repetitive jarring of running. Experts say the choice of activity matters less than warming up properly and pairing it with strength work.
A baby named Theo became the first British infant operated on in the womb to correct complex gastroschisis, a condition in which the intestines develop outside the body through an opening in the abdominal wall. The surgery, part of a pioneering clinical trial, aims to limit damage before the traditional postnatal repair takes place. Specialists say the approach needs further evaluation before it can be offered more widely.
Podiatrists repeat the same seasonal warning every summer: flat, backless flip-flops and slide sandals can cause heel pain, tendon strain and cracked skin. The problem stems from the constant toe-gripping needed to keep the sandal on and the lack of cushioning in most flat soles. Specialists say the fix is not avoiding sandals altogether but choosing more supportive styles and limiting how long the flattest ones are worn.
A four-month trial of 315 adults with central obesity found that a single weekly session of brisk interval walking cut body fat and waist size about as effectively as spreading the same amount of exercise across three days. Researchers say the finding could make exercise recommendations far easier to follow.
From marathon runners needing hip replacements to CrossFitters with ruptured ligaments, doctors say overuse injuries from pushing the body too hard are increasingly common. Physiotherapists explain why dedication to fitness can tip into damage, and how to spot the warning signs before surgery becomes the only option.
AI tools that automatically draft clinical notes are spreading fast through hospitals and medical schools. Educators are now split on whether letting trainee doctors rely on them early builds efficient habits or erodes the note-taking skills doctors need for careful clinical reasoning.
A new analysis finds that up to 95% of women under 50 who carry an elevated risk of breast cancer are missed by current NHS screening, which mostly begins at age 50. Researchers say risk-based checks, not age alone, may need to start earlier.
A mysterious virus that began killing horses, and then people, in 1990s Australia fundamentally reshaped how scientists understand diseases that jump from bats to other species. Adapted from a new book, this piece traces how researchers came to view the Hendra virus as a case study that foreshadowed today's coronavirus spillover science.
A ruling by the Michigan Supreme Court has cleared the way for state officials to investigate pharmaceutical company Eli Lilly's insulin pricing practices. The decision marks a significant development on the legal front of a long-running debate over insulin affordability in the United States.
US Health Secretary Robert F. Kennedy Jr. has called on families to vaccinate their children against measles amid an active outbreak, a statement reported as notable given his long-standing association with vaccine skepticism. The United States has experienced periodic measles outbreaks in recent years tied to declining vaccination rates.
Health officials are warning summer travelers about cyclospora, a parasite typically linked to contaminated fresh produce and water in popular travel destinations. The infection can cause severe and prolonged diarrheal illness, and experts are urging practical hygiene and food-safety precautions.
Researchers are working to explain why poor sleep appears to take a heavier toll on some people's brains than others. Emerging evidence points to individual variation in the brain's overnight waste-clearance system, along with genetic and age-related factors that may shape long-term vulnerability.
A major review of existing research examines whether reducing protein intake could slow biological aging by dampening growth-signaling pathways linked to cell division and repair. Researchers caution the evidence is largely observational and animal-based, and stress that older adults may need more protein, not less, to guard against muscle loss.
For four decades, doctors have treated a rise in BMI around age six, known as 'adiposity rebound', as an early warning sign of future obesity. New research suggests the rebound may reflect healthy muscle growth rather than fat gain, and that the theory needs a rethink.
From phone lockboxes at group events to pubs that ban devices at the door, a growing number of people are seeking out organised ways to put their smartphones down. Organisers say the appeal lies less in the tech itself than in the shared structure it provides.
