Epigenetic changes in twins and babies of dieting mothers increase obesity, diabetes risk

Epigenetic changes in gene structure lead to higher incidents of obesity and diabetes for mothers with poor nutrition at the time of conception. The study found that dieting around the time of conception and early pregnancy can alter genes controlling food intake and glucose levels, increasing the risk of obesity and type 2 diabetes.

How black holes grow

A University of Utah astrophysicist has proposed that supermassive black holes in galaxy centers grow by consuming single stars from wandering binary pairs. The study found that this process is an efficient way to bring stars close to black holes, outperforming gas clouds as a growth mechanism.

New discovery may lead to effective prevention and treatment of graft-versus-host dsease

Scientists have discovered that the platelet activating factor receptor plays a crucial role in graft-versus-host disease, which can cause significant tissue damage and mortality. Blocking this receptor may lead to reduced tissue injury and improved survival rates for patients undergoing bone marrow transplants.
