    Me, Myself, and Why

    Near the end of Ouellette’s new book — a personal journey exploring what shapes people’s sense of self — she pops a candy tablet of LSD and settles in for her first psychedelic experience. Ouellette had heard that once the drug wore off and the acid-induced wonderland slipped away, the “self” came barreling back.

    Power-packed bacterial spores generate electricity

    With mighty bursts of rehydration, bacterial spores offer a new source of renewable energy.

    Bacillus spores quickly shrivel in dry times and bloat with a blast of humidity. The transitions, which take about half a second, pack a powerful punch that biophysicist Ozgur Sahin at Columbia University realized could translate to usable energy. By smearing spores onto a flat piece of rubber...

    Corals may whip up whirlpools to spin specks of food in and bits of waste out. Scientists had known that hairlike bristles, or cilia, on coral help sweep nutrients in, but the purpose of bristles lining the valleys between coral polyps had been more mysterious. Using video microscopy, MIT environmental engineer Vicente Fernandez and colleagues recorded two short clips...
