Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism ...

Scientists have traced a devastating pattern of brain cell loss in a handful of families to a single, ultra-rare mutation that sabotages one of the brain’s key protective enzymes. The discovery not ...

A microscopic flaw in the brain’s cellular scaffolding can shape brain size for life.

In the mutation accumulation experiment, amoebae were allowed to reproduce until they formed a visible plaque, and then one was picked at random and carried to a new plate where it was allowed to ...

The disorder, which is linked to a mutation in a gene called ACAA2, can lead to low blood sugar, liver damage in babies, and ...

Some fungi live up to 2,500 years thanks to an internal system that eliminates harmful cells and prevents genetic mutations.

In the 1940s, the famous Luria–Delbrück experiment showed that bacteria evolve resistance to drugs they'd never encountered thanks to a random mutational process. When you purchase through links on ...

Scientists studying how microbes evolve have long assumed that nearly all new genetic mutations get passed down at a predictable pace and usually without either helping or hurting the microbe in ...

Robert Moffit, Ph.D., is a senior research fellow in the Center for Health and Welfare Policy at The Heritage Foundation. Dr. Jordon Trishton Walker, a director of research and development for the ...

Dr. Jordon Trishton Walker, a director of research and development for the Pfizer Corp., recently became an overnight internet sensation. The reason: In a set of rambling remarks to an undercover ...
