Immune cells in skin remember, defend against parasites

Just as the brain forms memories of familiar faces, the immune system remembers pathogens it has encountered in the past. T cells with these memories circulate in the blood stream looking for sites of new infection.

Tracking parasites with satellites

Scientists are teaming up to use satellite data to target deadly parasites to help predict patterns of parasitic diseases such as malaria, worms and hydatids.
