Everything, everywhere, all at once: Inside the chaos of Alzheimer’s disease

To truly understand Alzheimer’s disease, we may need to take a systems approach, in which inflammation, vascular injury, impaired glucose metabolism and other factors interact in complex ways.

Plaque levels differ in popular Alzheimer’s mouse model depending on which parent’s variants are passed down

5XFAD model mice that inherit two disease-related genes from their fathers have double the plaques seen in those with maternal inheritance, a new study shows.

Putting a bright idea to the test

A surprising wave of findings in mice suggests that light and sound flickering at 40 hertz clears the brain of Alzheimer’s-disease-linked plaques. Several companies are hoping to prove it works in people.

Grant review needs reform. How about we add an element of chance?

A process that uses a lottery system saves time, reduces strategic resubmission and accepts that, above a quality threshold, luck has always played a part in science funding.
