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 ...

Putting proteins in their proper place

A host of special molecules called nuclear RNA-binding proteins (RBPs), when misplaced outside the nucleus, form the harmful clumps seen in several brain disorders, including frontotemporal dementia (FTD) and amyotrophic ...

Cosmic magnifying lens reveals inner jets of black holes

Astronomers using Caltech's Owens Valley Radio Observatory (OVRO) have found evidence for a bizarre lensing system in space, in which a large assemblage of stars is magnifying a much more distant galaxy containing a jet-spewing ...

Chaining up diarrhoea pathogens

Researchers have clarified how vaccinations can combat bacterial intestinal diseases: vaccine-induced antibodies in the intestine chain up pathogens as they grow in the intestine, which prevents disease and surprisingly also ...

The lifetimes of massive star-forming regions

Astronomers can roughly estimate how long it takes for a new star to form: it is the time it takes for material in a gas cloud to collapse in free-fall, and is set by the mass, the size of the cloud, and gravity. Although ...

Molecules form gels to help cells sense and respond to stress

A specific protein inside cells senses threatening changes in its environment, such as heat or starvation, and triggers an adaptive response to help the cell continue to function and grow under stressful conditions, according ...

The stability of the solar wind

NASA's Wind spacecraft observes the solar wind before it impacts the magnetosphere of Earth. Launched in 1994 into an orbit more than two hundred Earth-radii away, one of Wind's prime objectives is to investigate the basic ...
