Plutonium tricks cells by 'pretending' to be iron
(PhysOrg.com) -- Plutonium gets taken up by our cells much as iron does, even though there's far less of it to go around.

Mapping the nuclear pore complex: 1.5 billion years of innovation
(Phys.org)—If asked to describe the differences between humans and frogs, a child might say that one hops and rib-its while the other walks and talks. If we ask that same child how to build a frog, they will probably need ...
New insights on an old polymer material, Nafion, will enable design of better batteries
Designing new materials depends upon understanding the properties of today's materials. One such material, Nafion, is a polymer that efficiently conducts ions (a polymer electrolyte) and water through its nanostructure, making ...
