High-tech tags on marine animals yield valuable data for biologists and oceanographers

...the same time, Costa's group was also tracking the movements of elephant seals and albatrosses. These species, which typically forage across a broad area of the North Pacific Ocean, showed little change in their movement patterns in 2004 and 2005. As platforms for ocean sensors, northern elephant seals and Cal...

Picking apart how neurons learn

...eflex. The vestibulo-ocular reflex coordinates eye movements with head movements, allowing us to perform activities such as reading in a moving automobile. "We've long known that LTD underlies responses like the vestibulo-ocular reflex. This study gets at the heart of how LTD occurs, specifically how PICK1 co...

Scientists directly view immune cells interacting to avert autoimmunity

...cells, rather than random activity. These directed movements are followed by prolonged interaction between autoimmune T cells and dendritic cells that lead to proliferation of autoimmune cells and eventually tissue destruction.
