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
An experimental drug called DT-109 reversed severe fatty liver disease in animal studies by repairing the gut and preventing harmful toxins from damaging the liver. The discovery could open the door to a new class of treatments for MASH and potentially other diseases tied to gut health.
Researchers found that every pregnancy rewires the brain in its own way, with a second pregnancy bringing a different pattern of changes than the first. The discoveries could lead to better ways to recognize and treat maternal mental health challenges, including peripartum depression.
Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that worked well enough for survival but still leave us prone to pain, injury, and disease. Structures like the appendix and ear muscles also remain because they were never harmful enough for evolution to eliminate. Together, these features tell the story of a body shaped by history rather than perfection.
Heavy marijuana smoking may raise the risk of lung cancer and several head and neck cancers, according to growing research, but many important questions remain unanswered. Scientists are still trying to determine how much marijuana use is enough to significantly increase cancer risk. Edibles have not been linked to lung cancer so far, while the long-term effects of vaping marijuana and secondhand marijuana smoke are still being investigated.
A naturally occurring bacterium from amphibian intestines completely eliminated colorectal tumors in mice with a single treatment by both attacking cancer cells and activating the immune system. The findings point to a promising new type of cancer therapy that could one day work against many solid tumors.
Scientists found that a modified Mediterranean-style diet with low protein and just enough methionine helped mice live healthier lives while reducing body fat and frailty. Human data also linked lower animal protein intake to lower rates of obesity and Type 2 diabetes, suggesting the approach could benefit people as well.
A new study debunks the long-standing claim that baby rattlesnakes are more dangerous than adults. Researchers found that young rattlesnakes can control their venom just like adults, while adult snakes usually inject much more venom and cause more serious bites. The team also uncovered how the myth spread through decades of inaccurate news reports and misleading quotes from trusted sources.
Researchers found that mRNA cancer vaccines can recruit an unexpected immune cell to launch powerful tumor-fighting responses, overturning a long-held assumption about how the vaccines work. The discovery could lead to more effective cancer vaccines and help scientists tailor treatments for better patient outcomes.
A surprising discovery is reshaping scientists' understanding of how humans develop sharp central vision before birth. Instead of blue cone cells migrating away from the retina's center, the study found they transform into red and green cones under the influence of vitamin A-related signals and thyroid hormones. The findings could improve lab-grown retinal tissue and lay the groundwork for future cell therapies to restore vision lost to age-related eye diseases.
Poison control calls involving semaglutide (Ozempic and Wegovy) soared after the drug was approved for weight management, with researchers linking the increase to accidental dosing mistakes rather than intentional misuse. Simple education about proper weekly dosing and gradual dose increases could help prevent many of these avoidable incidents.
Scientists have created a silicon chip that can write dozens of DNA sequences simultaneously using electricity and water-based enzymes, offering a cleaner alternative to conventional DNA manufacturing. The breakthrough could eventually support portable DNA-writing devices and even massive DNA data storage, although new chemistry will be needed to scale the technology further.
Tiny silica nanoparticles engineered to seek out prostate cancer caused tumor cells to self-destruct and supercharged the immune system in preclinical mouse studies. Combined with immunotherapy, the treatment produced complete remissions in multiple mice, raising hopes for a powerful new approach to prostate cancer.
California’s next governor will face tough decisions on a highly controversial piece of healthcare policy: what to do about health coverage for the more than 1.4 million low-income residents without legal status. Democrat Xavier Becerra and Republican Steve Hilton present starkly different choices as public opinion wavers.
Drugmakers provide financial assistance to help patients afford increasingly expensive medications. But some insurers do not count those payments toward a plan’s deductible or out-of-pocket maximum and make patients pay instead.
Over the past 70 years, the number of inpatient psychiatric beds has dropped dramatically, leaving many without critical care when they experience mental health crises. I was one of the lucky ones to get a bed — after 21 hours of waiting.
Insurers that sell plans in Obamacare marketplaces across 16 states and the District of Columbia have asked regulators to approve a 14% median premium increase for 2027, according to a new Peterson-KFF analysis.
Many Americans are shopping around for affordable options as the cost of health insurance soars. But some who hope to keep the same doctors and medications face a thicket of red tape and disruption after they switch plans.
Thousands of people who had a Medicare drug plan with zero-dollar premiums last year got small premium increases this year — and didn’t know it. They were dropped from their coverage for failing to pay amounts as little as $8, and most can’t get it again until 2027.
