Explore just how indispensible mass spectrometry is becoming to life science researchers.

The authors propose that the shots might keep the immune system primed to battle diseases that would otherwise contribute to cognitive decline.

The cell conversion strategy restores neurons and motor functions lost as a result of an induced Parkinson’s-like illness in the animals.

The gene, aquaporin-4, is critical in rodents for the cerebrospinal fluid bath the brain gets during sleep. It’s now also tied to slow wave electrical activity during deep sleep in people.

This year’s most beautiful illustrations covered topics including the molecular underpinnings of Parkinson’s disease and strategies for tracking marine organisms around the world’s oceans.

A look at some of the circulating molecules that may indicate various Alzheimer’s pathologies and serve as the bases of noninvasive tests for the disease.

Researchers hope circulating biomarkers will enable earlier detection and better monitoring of the neurodegenerative disorder—and perhaps help usher in new treatments.

New evidence points to a waste-clearing problem in patients’ cells, rather than the accumulation of protein tangles, as the root cause of the neurodegenerative disease.

Evidence is accumulating that breathing contaminated air might impair cognition.
