An experimental drug developed at Michigan Medicine has shown the ability to reverse severe fatty liver disease in animal studies by restoring gut health. The findings, published in The Journal of Clinical Investigation, suggest that targeting the connection between the gut and liver could offer a promising new approach for treating metabolic dysfunction-associated steatohepatitis (MASH).

The success of mRNA vaccines against SARS-CoV-2 during the COVID-19 pandemic transformed vaccine science. Now, the same Nobel Prize winning technology is being adapted to fight cancer, with experimental mRNA vaccines already being tested against melanoma, small cell lung cancer, bladder cancer, and several other cancers. Researchers hope these vaccines could eventually provide powerful new ways to prevent and treat the disease.

Scientists at Johns Hopkins University have uncovered how humans develop sharp central vision before birth, identifying a carefully timed interaction between a vitamin A derived molecule and thyroid hormones in the retina. The discovery challenges a decades old explanation for how key light sensing cells form and could guide future treatments for macular degeneration, glaucoma, and other diseases that damage vision.

For much of the early 20th century, quantum mechanics was one of the most puzzling ideas in science. The theory challenged conventional thinking and left even leading physicists struggling to make sense of its implications. A century later, it has become the foundation of technologies that influence daily life, including lasers, microchips, secure communications, and emerging quantum computers.

Creatine is one of the world's most popular sports supplements, widely used to improve strength and muscle performance. Now, researchers are exploring whether it could have benefits far beyond the gym. A new systematic review published in Brain Medicine examined whether creatine might help relieve depression by supporting the brain's energy needs.

Researchers at the University of Oxford have created a new calculator that estimates a person's individual risk of developing serious muscle disorders while taking statins. The tool is designed to help patients and doctors make more informed decisions about these commonly prescribed cholesterol lowering medications, which are widely used to prevent heart attacks and strokes.
