Defective glial cells can push neurons toward Parkinson's disease

Researchers from the University of Barcelona have shown that defective versions of human brain cells called astrocytes are linked to the buildup of a toxic protein that is the hallmark of Parkinson's disease. The studied ...

Why human eyes are wired backwards

The human eye is optimised to have good colour vision at day and high sensitivity at night. But until recently it seemed as if the cells in the retina were wired the wrong way round, with light travelling through a mass of ...

Genetics

The surprising twist behind a rare neurological disorder

A fruit fly study, by an international group of researchers, has pinpointed how a genetic mutation causes one of the important molecular machines in our cells to malfunction. The findings provide a biological mechanism behind ...

Alcohol kills brain cells: Addressing a medical myth

Do you ever wake up with a raging hangover and picture the row of brain cells that you suspect have have started to decay? Or wonder whether that final glass of wine was too much for those tiny cells, and pushed you over ...

Why get a filling when you could print a new smile?

Twinges. Painful teeth. About one in 10 people suffer from dental sensitivity caused by worn enamel. But rather than providing short-term solutions like special toothpastes or fillings, new techniques could print whole new ...

ALS treatment delays disease and extends life in rats

Investigators at Cedars-Sinai are exploring a new way to treat amyotrophic lateral sclerosis (ALS) by transplanting specially engineered neural cells into the brain. Their new study shows the transplanted cells delayed disease ...

How glial cells develop in the brain from neural precursor cells

Two types of cells are active in the brain: nerve cells and glial cells. Glial cells have long been regarded primarily as supportive cells, but researchers increasingly recognize that they play an active role in the communication ...
