Why alcohol blocks the liver from healing, even after you quit

Alcohol doesn’t just damage the liver — it locks its cells in a strange “in-between” state that prevents them from healing. Even after someone quits drinking, liver cells often get stuck, unable to function normally or regenerate. Scientists have now traced this problem to runaway inflammation, which scrambles the cell’s instructions and silences a key helper protein. By blocking these inflammatory signals in lab tests, they were able to restore the liver’s healing ability — a finding that could point to new treatments beyond transplants.

Metformin offers no strength training benefits for seniors, study shows

A clinical trial argues against the hypothesis that the diabetes drug metformin could help exercising seniors gain more muscle mass. The double-blind trial found that older adults who took metformin while performing rigorous resistance exercise training had smaller gains in muscle mass than the placebo group.

Researchers developing new 'DNA stitch' to treat muscular dystrophy

A new therapeutic being tested is showing early promise as a more effective treatment that could help nearly half of patients with Duchenne muscular dystrophy (DMD). The treatment — a cocktail of DNA-like molecules — results in dramatic regrowth of a protein called dystrophin, which acts as a support beam to keep muscles strong. The protein is virtually absent in those with DMD.

Gene editing enables researchers to correct mutation in muscle stem cells in DMD model

Duchenne muscular dystrophy (DMD) is a rare but devastating genetic disorder that causes muscle loss and physical impairments. Researchers have shown in a mouse study that the powerful gene editing technique known as CRISPR may provide the means for lifelong correction of the genetic mutation responsible for the disorder.
