Evaluating a new way to open clogged arteries

Over the past few decades, scientists have developed many devices that can reopen clogged arteries, including angioplasty balloons and metallic stents. While generally effective, each of these treatments has drawbacks, including the risk of side effects. A new study from MIT analyzes the potential usefulness of a new treatment that…

Sorting out the structure of a Parkinson’s protein

Clumps of proteins that accumulate in brain cells are a hallmark of neurological diseases such as dementia, Parkinson’s disease and Alzheimer’s disease. Over the past several years, there has been much controversy over the structure of one of those proteins, known as alpha synuclein. MIT computational scientists have now modeled…

Despite their widespread use, little is known about how these drugs create such a profound loss of consciousness. In a new study that tracked brain activity in human volunteers over a two-hour period as they…

A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no…
