In a healthy brain, millions of nerve cells, known as neurons, receive and transmit electrical signals. Together, these transmissions enable communication within the brain, as well as between the brain and other organs, systems, and body parts. In individuals with Alzheimer s disease, deteriorating neurons lose this essential ability to communicate and eventually die, severely inhibiting critical brain functions like memory, language, and reasoning.
Plaques and Tangles
In patients with Alzheimer s, researchers have studied two specific molecular and cellular changes within the brain. First, a protein known as amyloid precursor protein breaks down, causing abnormal levels of amyloid proteins to accumulate in clumps among the neurons. These clumps, known as amyloid plaques, interfere with neurons ability to communicate with one another and can eventually contribute to the cell s deterioration.

The impact of atmospheric aerosols on clouds and climate may be different than previously thought. That is the conclusion of cloud researcher Franziska Glassmeier from TU Delft. The results of her study will be published in
Science on Friday, January 29th.
Clouds
Cloud decks cover vast stretches of the subtropical oceans. They cool our planet because they reflect incoming sunlight back to space. Air pollution in the form of aerosols particles suspended in the atmosphere can increase this cooling effect because it makes clouds brighter. The cooling effect of pollution offsets part of the warming effect of greenhouse gases. How much exactly, is one of the largest uncertainties faced by climate scientists
