Discovering he is getting old before his time, David Cox tries to lower his biological age by changing his diet in a helpful new book, The Age Code, says Graham Lawton
Exercise has been touted as a tool for managing and treating long covid, but much of the evidence has neglected one of its most debilitating symptoms: post-exertional malaise
A traditional vaccine primes the immune system to build better defences. Researchers think we can do something similar to increase our resilience to the pressures and worries of life
Stress is linked to many of our biggest killers, but a growing body of research suggests that certain types can sharpen the mind and strengthen the body. Here’s how to find your perfect dose
People who are terminally ill are commonly reunited with lost loved ones in their dreams and have visions of doors, stairways and light, which are said to help them accept the dying process
Patients are requesting that blood transfusions come from people who they know have not been vaccinated against covid-19, which can cause dangerous delays
The protein craze is in full swing and beef consumption is on the rise, particularly in the US, where health agencies are promoting red meat as part of an optimum diet. So, how much beef should we really be eating, and how does it impact our well-being?
A study of more than 10 million siblings suggests that firstborns are more likely to be autistic and have allergies, while conditions like migraine and shingles tend to affect their younger sibling
Some gut bacteria recycle discarded sex hormones, like oestrogens, back into the body. The level of these bacteria seems to be higher in industrialised societies, which could have big implications for our health
A woman with three different autoimmune conditions had all of them treated simultaneously by genetically modifying her immune cells to kill off the rogue ones causing problems
A drug known only as compound X helped to remove the problematic proteins associated with Parkinson's disease from the brains of mice, and improved their balance and mobility
Scientists have uncovered a key brain signal that helps us break old habits and adapt when circumstances suddenly change. By watching mice navigate a virtual maze, researchers found that disappointment—when an expected reward failed to appear—triggered a surge of the neurotransmitter acetylcholine, making the animals more likely to try a new strategy. When acetylcholine was blocked, the mice became less flexible and were more likely to stick with outdated choices.
A major long-term study of more than 54,000 adults found that where nitrate comes from may matter far more than how much you consume. People who got more nitrate from vegetables—roughly the amount in a cup of baby spinach a day—had a lower risk of developing dementia, while higher nitrate and nitrite intake from red meat, processed meat, and even drinking water was linked to a greater risk.
A trio of major studies found that finerenone may protect the kidneys and heart in far more people than previously thought. The drug significantly slowed kidney disease progression and reduced the risks of kidney failure, heart failure, cardiovascular death, and overall mortality. Researchers saw benefits not only in patients with diabetes but also in those with non-diabetic kidney disease, a group with limited treatment options.
A traditional Chinese medicinal root used for over a thousand years is attracting new scientific attention for its potential to combat hair loss. Studies suggest Polygonum multiflorum can block harmful hormones, activate hair-growth signals, protect follicles, and boost blood flow to the scalp. Researchers say the herb’s effects align remarkably well with both ancient descriptions and modern hair biology.
A large study found that women taking GLP-1 drugs, the medication class behind Ozempic, Wegovy, Mounjaro, and Zepbound, were about 30% less likely to develop breast cancer. Researchers say the findings are promising but not yet proof, and clinical trials are now being planned to test whether these drugs could help prevent breast cancer.
Supplements are often marketed as shortcuts to better health, but for many older adults, the real issue is whether they have a specific deficiency. Vitamins like B12 and D can play an important role when levels are low, while protein may be one of the most overlooked nutrients for maintaining strength and independence. More isn’t always better, though—some supplements can cause harm or interact with medications.
Scientists warn that free-living amoebae may be an underappreciated public health threat, capable of causing deadly infections and shielding other dangerous microbes from water treatment. Climate change and aging infrastructure could help these resilient organisms spread more widely in the years ahead.
Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS, and related bat viruses with pandemic potential. By targeting features shared across an entire virus family, it aims to provide protection even as viruses evolve.
Scientists have identified genetic variants that may make some people less responsive to GLP-1 drugs used to treat Type 2 diabetes. Roughly 10% of the population carries these variants, which appear to cause a mysterious form of "GLP-1 resistance." In several clinical trials, carriers were significantly less likely to reach healthy blood sugar targets while taking GLP-1 medications.
A major review of nearly 8,000 participants found that collagen supplements can improve skin health and ease osteoarthritis symptoms, especially when taken consistently over longer periods. Researchers also found modest benefits for muscle and tendon health. But the results challenge claims that collagen enhances sports performance, as it showed little effect on recovery or post-workout soreness.
A large study of older adults in Brazil found that adding extra salt at the table is still a common habit, especially among men. While too much salt is linked to serious health problems and faster cognitive decline, researchers discovered that women’s salt-shaking habits were tied more closely to lifestyle and diet.
For decades, pancreatic cancer has been one of the most lethal cancers, with few effective treatment options. A new drug, daraxonrasib, targets the KRAS mutation that fuels most pancreatic tumors—something many scientists once thought couldn't be done. In a major clinical trial, the treatment nearly doubled survival for patients with advanced disease and reduced the risk of death by 60%.
Health secretary Robert F. Kennedy Jr.’s new autism panel is championing a controversial communication method popular among parents of severely autistic people. Critics warn of abuse — and fake “telepathy.”
Big cuts to healthcare programs in the 2025 GOP budget law are creating an affordability crunch for many Americans: Higher health insurance premiums. Confusion about who Medicaid will cover under the new rules. KFF Health News chief Washington correspondent Julie Rovner explains how the changes could leave nearly 2 million children uninsured.
Come January, pregnancy care physician billing codes will change from a bundled system to an à la carte one. Many obstetricians say this approach will better reflect the amount and type of care they provide. But it could incentivize providers to pile on visits and services.
Travel bans and conflict have disrupted supply chains in the Democratic Republic of Congo, leaving health workers without Ebola tests and protective gear needed to contain the outbreak.
To collect and scrutinize millions of Americans’ health data, U.S. health secretary Robert F. Kennedy Jr. aims to work with state organizations that help health systems share medical records. In Nebraska, millions in federal dollars has flowed into one nonprofit cooperating with Kennedy’s project.
