Chronic illness

Researchers have demonstrated how a secret weapon made in the gut, produced by consuming pomegranate and walnuts, can rejuvenate the immune system in middle age, shielding us from cell damage, inflammation and chronic diseases including cancer.

Millions of people with type 2 diabetes might actually be undermining their efforts to improve their health, with researchers demonstrating that the commonly prescribed metformin blocks the cardiovascular benefits normally gained through exercise.

In a groundbreaking study, scientists have cultivated and then awoken more than 100 new viruses found within different human gut microbes, providing a remarkable look at our bacteria and forms the very first living model of the "gut virome."

A first-of-its-kind study has found that recognizing – and using – personal strengths is linked with better physical and psychological wellbeing and fewer mental-health challenges in adults with attention-deficit/hyperactivity disorder.

Friendships, community ties and family bonds may apply the brakes to cell aging, providing a simple way to invest in health in older age. In a new study, scientists find that social connections are tied to slower biological aging and less inflammation.

Researchers believe they have developed the first blood test to diagnose chronic fatigue syndrome, or myalgic encephalomyelitis, and it has the potential to be a game-changer for millions around the globe suffering with the debilitation condition.

A simple haircut may reveal more than just split ends. By testing for the stress hormone cortisol, which is stored in hair, researchers can identify kids with chronic illness who face the greatest risk of anxiety, depression, or behavioral struggles.

When scientists study obesity, it's often focused on genetics, physical activity and poor eating habits. However, new findings show that stress, hardship, isolation and social inequality create the biological environment that underpins the epidemic.

A new drug candidate could become a first-in-class medication, after impressive results in a mid-stage clinical trial for drug-resistant epilepsy. It now moves to Phase 3 trials, raising hope for people who suffer seizures despite being on medication.

People who eat high ultra-processed diets have a specific elevated health marker that's a telltale sign of chronic inflammation – even without any symptoms. This inflammation is a slow burn, contributing to diseases likes heart conditions and diabetes.

When we eat as we get older changes, but what impact this has on our health isn't well understood. New research, however, has found that in midlife and beyond, eating one particular meal later in the day is linked with a higher risk of early death.

A new study combining brainwave monitoring and machine learning has found that certain types of music can dramatically reduce motion sickness symptoms – by more than half in some cases – offering fresh hope for more pleasant travel experiences.
