Scientists have uncovered a surprising link between dark chocolate and slower aging. A natural cocoa compound called theobromine was found in higher levels among people who appeared biologically younger than their real age.

Researchers discovered that nerve injuries can alter the immune system throughout the body, and males and females react very differently. Male mice showed strong inflammatory responses, while females showed none, yet both transmitted pain-inducing .. ...

Long COVID still affects people worldwide with stubborn symptoms like fatigue and cognitive issues. A clinical trial tested whether boosting NAD+ using nicotinamide riboside could help. Although overall group differences were limited, many ...

Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility ...

Researchers found that both how often and how much someone drinks significantly shape their cancer risk, even at moderate levels. Vulnerability varies across groups, with genetics, socioeconomic status, obesity, and lifestyle behaviors amplifying ...

Scientists discovered that the protein RPA plays a critical and previously unconfirmed role in stimulating telomerase to maintain long, healthy telomeres. When RPA malfunctions, telomeres can shorten dangerously, leading to serious diseases.

A cutting-edge therapy using base-edited immune cells is offering a major breakthrough for patients with one of the toughest forms of blood cancer, T-cell acute lymphoblastic leukaemia. By precisely rewriting tiny sections of DNA, scientists at UCL . ...

Northwestern scientists have created the fastest-ever hepatitis C diagnostic, delivering accurate results in only 15 minutes. The test uses the DASH rapid PCR system, originally developed for COVID, but adapted for whole blood samples. Independent .. ...

Scientists discovered that certain cancer cells use a low-level activation of a DNA-dismantling enzyme--normally seen in cell death--to survive treatment. Instead of dying, these "persister cells" leverage this sublethal signal to regrow. Because the ...

Researchers uncovered how shifting levels of a brain protein called KCC2 can reshape the way cues become linked with rewards, sometimes making habits form more quickly or more powerfully than expected. When this protein drops, dopamine neurons fire . ...
