Purdue proves concept of using nano-materials for drug discovery

...round cells and regulate the movement of molecules into and out of the cells, contain a variety of proteins, some of which are directly responsible for cancer's ability to resist anti-tumor chemotherapy drugs. These proteins act as tiny pumps that quickly remove chemotherapy drugs from tumor cells, making...

In the sea slug's defense against lobsters, confusion is key

...ug's ability to trick the lobster's nervous system into activating feeding-associated behaviors succeeds, in combination with ink and opaline's other effects, in distracting the lobster sufficiently to enable the slug's successful evasion. Because the set of behaviors stimulated by the slug's secretions ...
