More than 70% of neurological diseases, including Alzheimer's disease and the concussion-related disorder CTE, are believed to be fueled by protein clusters called tau aggregates. A new study sheds light on how they damage brain cells and could ultimately lead to new therapies for such "tauopathies."

Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.

One of the most comprehensive statistical analyses of drivers of food insecurity across 65 countries has concluded that household income consistently explains more discrepancy in food security than any other factor, including agricultural land resources and production.

Results suggest vaccination against COVID-19 remains crucial even in young adults who were previously infected.

Russian scientists have proposed a theory of phase transformation in polymer gels. It explains the mechanisms of the dramatic reduction in volume of zwitterionic hydrogels when they are cooled. The results are published in the journal Chemical Communications (ChemComm).

New research sheds light on how autism-spectrum disorder manifests in the brains of girls, prompting the scientists to warn that conclusions drawn from studies conducted primarily in boys should not be assumed to hold true for girls.
