Scientists may have finally found how Alzheimer's spreads through the brain

A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow

Climate scientist who “proved” humanity is warming Earth says government report got it wro

A pioneering climate scientist is challenging a U.S. government report that cited his research while reaching what he says is the exact opposite conclusion. Benjamin Santer and his colleagues say decades of satellite data clearly reveal the atmospheric “fingerprint” of human-caus

Nanozymes map nanoparticle routes inside live cells without genetic engineering

Nanoparticles are widely used in medicine to deliver drugs, genes or imaging agents to specific parts of the body. Once a nanoparticle reaches a cell, however, many things can happen—it can reach its target, be degraded, interact with proteins that help transport it, or interact
