Young researchers Jan Gralton and Sven-Eric Schelhorn are fascinated by the minute world of viruses. They have plenty of questions for Harald zur Hausen who won a Nobel Prize for proving that human papillomaviruses (HPV) can cause cervical cancer

(PhysOrg.com) -- Harvard physicists have expanded the possibilities for quantum engineering of novel materials such as high-temperature superconductors by coaxing ultracold atoms trapped in an optical lattice -- a light crystal -- to self-organize into a magnet, using only the minute disturbances resulting from quantum mechanics. The research, published in the journal Nature, is the first demonstration of such a “quantum magnet” in an optical lattice.
