Chemists reveal how tau proteins form tangles

One of the hallmarks of Alzheimer's disease is the presence of neurofibrillary tangles in the brain. These tangles, made of tau proteins, impair neurons' ability to function normally and can cause the cells to die.

Team simulates how Alzheimer's disease spreads through the brain

For the first time, scientists have developed a computer simulation of how clumps of defective proteins in neurodegenerative diseases like Alzheimer's spread through the brain, much of the time in stealth mode, over as long ...

Weed scientist finds slight rise in herbicide chronic toxicity

A University of Wyoming weed scientist—frustrated with the noise surrounding genetically modified organisms and glyphosate use—analyzed data to see for himself if biotech adoption has had a negative or positive effect ...

Using heat to beat toxins

Researchers have developed a promising way to cleanse the environment of volatile organic compounds (VOCs) – some of the most insidious toxins known to humans.
