Once dismissed as “junk,” a group of RNA molecules has been found to help regrow damaged nerves in mice in new research. The discovery could unlock new ways to treat nerve injuries and even restore growth in the brain and spinal cord.

Cutting a single amino acid from the diet caused rapid, drastic weight loss in mice by converting white fat into calorie-burning brown fat. The study reveals a powerful new mechanism for weight loss that doesn’t rely on eating less and moving more.

A new study published in Nature Microbiology has reported a naturally occurring family of bacterial species in the human gut that can absorb and break down toxic, long-lasting "forever chemicals" and carry them out as waste through feces.

Researchers from Caltech have developed a wireless smart capsule packed with tiny sensors to monitor the workings of your GI tract. This could help us get a better sense of our gut health, with the convenience of a pill you can swallow.

New research suggests that expectations are associated with asthma outcomes. People who thought more negatively about their condition reported worse symptoms, adding to growing evidence about the mind-body connection and its influence on health.

A type of medicine commonly used to treat everything from chronic obstructive pulmonary disease to depression has now been linked to accelerating the loss of mobility in older age. These anticholinergic drugs have already been linked to dementia.

Scientists have discovered a brain circuit that gives pain its emotional sting, explaining why some hurts linger as suffering. The breakthrough challenges our beliefs about how we process pain and may transform chronic pain treatments.

Dopamine doesn’t flood the brain as once believed – it fires in exact, ultra-fast bursts that target specific neurons. The discovery turns a century-old view of dopamine on its head and could transform how we treat everything from ADHD to Parkinson’s.

A new study reveals that Americans are confused about what “processed food” actually means, and which types pose health risks. Researchers found major gaps between public perception and science, highlighting the need for more comprehensive education.

An extremely popular nerve pain drug commonly given to those suffering from low-back issues has been linked to impaired mental health including dementia and mild cognitive impairment. The risk was present after six or more prescriptions were filled.

Engineers at MIT have developed a coin-sized device that can be safely implanted in the body to automatically deliver a dose of glucagon when a sensor notices blood glucose levels dropping too low – and potentially save the user's life.

Picking up where traditional antibiotics are failing, two natural compounds have been shown effective in killing antibiotic-resistant bacteria in wastewater. The finding could point towards a natural way to defeat the increasingly undefeatable bugs.

Humans have been getting infected by ancient bacteria and viruses for at least 37,000 years. Now, for the first time, pathogen DNA has uncovered a pivotal disease "turning point" that happened 6,500 years ago, which would forever change our lives.

If you could get a quick, easy scan in your 40s, which could add decades to your life and aging healthily, would you? Scientists have made such a tool, letting you glimpse into a crystal ball that identifies age-related disease risk long before onset.

Choosing a type of exercise that matches your personality might mean you’re happier working out and achieve better results, according to a new study. The research highlights the benefits of a “psychologically personalized” approach to fitness.
