Deep-sea mussels still show biological rhythms tracking sunlight, tides

Like many land animals, marine organisms follow daily and seasonal clocks—in the water, those clocks are set by the cadence of the sun and the moon. But researchers hadn’t known if deep-sea creatures also exhibit biological rhythms, tucked away in … Continue reading

Country-level assessment hides big variations in soy’s carbon footprint

Analysts usually estimate a crop’s carbon footprint based on country-level factors. But that formulation isn’t adequate, according to a new analysis of soy exports from Brazil. Published in Global Environmental Change, the study tracked soy from specific production sites in … Continue reading

Neurons in the hippocampus can make several different maps of the same environment

Nestled deep in the brain, the hippocampus is the seat of spatial cognition. Specialized hippocampal neurons fire in consistent patterns thought to construct mental maps that help us navigate the world—in general, researchers believed there was one map for every … Continue reading
