Their study of curved shells and curved-crease origami revealed how structures can develop multiple stable configurations, including unexpected states created by deformation known as pseudocreases.

Psychology says women who always wear a scarf in winter may be following a comfort cue their brain has learned to trust

A woman who always puts on a scarf before stepping outside may simply prefer the warmth, comfort or familiarity it provides. That habit alone says very little about her personality. There is no solid evidence that wearing a scarf can reliably indicate anxiety, introversion, heightened sensitivity, a need for security or a strong dependence on routine.

In 2019, 1,500 volunteers counted seals in 90,000 drone photos of a California island; some counts came within 5% of expert totals

In 2019–2020, over 1,500 citizen scientists analyzed 90,000+ drone images to count wildlife on California's Año Nuevo Island. During winter breeding season, volunteers matched expert seal counts within 5%, but accuracy dropped sharply (to ~46%) when sea lions and seals shared beaches simultaneously, causing species confusion. Researchers found that averaging counts from 11+ volunteers, using medians while discarding low outliers, improved reliability, demonstrating citizen science works well for simple, single-species identification tasks but struggles with species overlap.
