Researchers found that the offspring of water fleas (Daphnia magna) exposed to nanoparticles of titanium dioxide react significantly more sensitively than the offspring of parents from a control group. This is the case even though the offspring themselves are not exposed to the nanoparticles.

Researchers at MIT have fabricated a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. The concave lens exhibits a property called negative refraction, bending electromagnetic waves - in this case, radio waves - in exactly the opposite sense from which a normal concave lens would work.

Drawing heavily upon nature for inspiration, a team of researchers has created a new artificial lens that is nearly identical to the natural lens of the human eye. This innovative lens, which is made up of thousands of nanoscale polymer layers, may one day provide a more natural performance in implantable lenses to replace damaged or diseased human eye lenses, as well as consumer vision products; it also may lead to superior ground and aerial surveillance technology.

We can look through glass, but what glass itself looks like on the inside has so far remained a mystery - at least as far as the precise position of the atoms is concerned. Scientists at the Fritz-Haber-Institute of the Max Planck Society in Berlin are now the first to have imaged the network of silicon and oxygen atoms - the main components of glass - in a silica film.

Röntgenstrahlen in einer Box 'auf Eis zu legen' und später nach Belieben wieder freizusetzen, klingt nach Science Fiction. Neue Rechnungen zeigen jedoch, dass mithilfe eines Magnetfelds einzelne Röntgenquanten eingefangen und ohne Qualitätsverlust wiedergewonnen werden können. Ausserdem ist es möglich, das gespeicherte Röntgenquant zu manipulieren, insbesondere seine Phase kontrolliert zu ändern.

Cell phones as thin and flexible as a sheet of paper. Energy-??storing house paint. Roll-??up touch screen displays. But if any of them is to work, said Northeastern University mechanical and industrial engineering professor Yung Joon Jung, experts also need to create a thin and flexible energy-??storage system. His lab has developed such a system.
