There are more than 600 muscles in the human body, and it's impossible to strengthen each and every one. Yet there are plenty whose power you can enhance, and doing so is key to enjoying a healthy, active life.

Rare bacterial infections, such as invasive strep A, are popping up around the United States and Europe, with unusual effects for children.

Scientists from Oxford University and the University of Birmingham have made the first bone marrow ‘organoids’ that include all the key components of human marrow. This technology allows for the screening of multiple anti-cancer drugs at the same time, as well as testing personalised treatments for individual cancer patients.

Children born without a working immune system due to a rare genetic disorder called Artemis-deficient severe combined immunodeficiency (Artemis-deficient SCID) may be able to lead normal lives thanks to a new gene-replacement therapy. A trial found that the therapy either partially or fully restored the immune systems of 10 infants with the condition.

A 13-year-old girl became the first-ever patient to receive a base-editing therapy, and her leukemia went into remission. Here's how it works.

A new study finds that nearly 6% of the estimated 130 million people who go to US emergency rooms every year are misdiagnosed, which translates to about 1 in 18 patients getting the wrong diagnosis.

Gene therapies promise long-term relief from intractable diseases—if insurers agree to pony up.

Researchers hope the vaccine, which blocked the drug from entering rats’ brains, could help reduce overdoses in humans

Authorities have urged anyone suffering from a range of severe symptoms after eating it to go to hospital.

It uses the same messenger-RNA technology as some Covid-19 vaccines.

A new study published in the journal PLoS ONE has reported on the first human tests of an experimental therapy using sound and light to treat Alzheimer's disease (AD). The initial findings are promising.

New Zealand will phase in a near-total tobacco ban from next year. Legislation passed by parliament on Tuesday means that anyone born after 2008 will never be able to buy cigarettes or tobacco products.

A lawsuit filed by New Jersey will attempt to hold Ford accountable for decades of environmental damage to native lands. Richard Hall talks to the residents still fighting for justice.

New way of altering DNA is used to engineer an "exciting", experimental therapy for a 13-year girl.

Every time you flush a toilet, it releases plumes of tiny water droplets into the air around you. We used lasers to show how, writes John Crimaldi.

A study shows that a substance in the drink kefir can help combat disease-causing, antibiotic resistant bacteria by disrupting their communication.

"Immunity debt" can explain this year’s eye-popping cold and flu season — but it can also be dangerously misinterpreted.

Lecanemab is the first drug to remove damage, but there are questions around its impact, side effects and use.

Preliminary results offer hope that gene therapy can protect people with a version of the brain disease driven by a particular gene variant.

Assuming rejuvenation research continues to progress, and is to some degree successful, a lot of our attitudes towards death will change.
