Prehistoric Pacific Coast diets had salmon limits

Researchers have found that prehistoric Pacific Coast people employed various dietary solutions to balance their diet and avoid 'salmon starvation'. They offset stored salmon protein with acorns, root crops like camas, and fat-heavy fish, and traded or processed bone marrow from caribou and elk.

Imbalance in gum bacteria linked to Alzheimer's disease biomarker

A study by NYU College of Dentistry and Weill Cornell Medicine found that older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid beta, a key biomarker for Alzheimer's disease. The researchers suggest that high levels of 'good' bacteria may be protective against Alzheimer's.

Decreased winds and onset of autumnal leaf changes

A 34-year climate study reveals that decreased wind speed is associated with delayed onset of annual leaf drop, extending favorable growth conditions later into autumn. The authors suggest that reduced soil drying due to decreased winds may be a key factor in this phenomenon.

Study snapshot: Untested admissions

A study found that test-optional admissions policies at selective private institutions led to a 3-4% increase in Pell Grant recipients, a 10-12% increase in first-time Black, Latinx, and Native students, and a 6-8% increase in women enrollment. However, these gains were relatively small compared to the overall student body.
