Researchers discover insights into amyloids associated with Alzheimer’s and type 2 diabetes

A Virginia Tech research team has discovered insights into the stabilizing forces of amyloid fibrils that are associated with Alzheimer’s disease and type 2 diabetes. These findings were recently published in the Journal of Molecular Biology. Amyloids are aggregates of proteins that form a shape that allows many copies of that protein […]

Cells stop dividing when this gene kicks into high gear, study finds

Scientists seeking to unlock the secrets of cellular aging have identified a gene that triggers senescence, a phenomenon in which cells stop dividing. Senescence is a natural occurrence in the life of a cell, and researchers have sought to learn about it for a couple of reasons. First, it’s connected […]

Scientists solve the case of the missing subplate, with wide implications for brain science

The disappearance of an entire brain region should be cause for concern. Yet, for decades scientists have calmly maintained that one brain area, the subplate, simply vanishes during the course of human development. Recently, however, research has revealed genetic similarities between cells in the subplate and neurons implicated in autism—leading a […]

Not Junk: ‘Jumping Gene’ is Critical for Early Embryo

A so-called “jumping gene” that researchers long considered either genetic junk or a pernicious parasite is actually a critical regulator of the first stages of embryonic development, according to a new study in mice led by UC San Francisco scientists and published in Cell. Only about 1 percent of the human […]

Toward a Cure for Sickle Cell: How Doctors Are Fighting a Crippling Disease

Each year, 300,000 infants worldwide are born with a genetic disease that warps the shape of their red blood cells, which break apart and fail to deliver life-giving oxygen, or pile up in tiny blood vessels and result in episodes of severe pain, swelling of hands and feet, organ damage, […]
