'Metascreen' forms ultra-thin invisibility cloak
Up until now, the invisibility cloaks put forward by scientists have been fairly bulky contraptions -- an obvious flaw for those interested in Harry Potter-style applications.

Nanowire solar cells raise efficiency limit
Scientists from the Nano-Science Center at the Niels Bohr Institut, Denmark and the Ecole Polytechnique Fédérale de Lausanne, Switzerland, have shown that a single nanowire can concentrate the sunlight up to 15 times of the normal sun light intensity. The results are surprising and the potential for developing a new type of highly efficient solar cells is great.

New chemo drug gentler on fertility, tougher on cancer
A new gentler chemotherapy drug in the form of nanoparticles has been designed by scientists to be less toxic to a young woman's fertility but extra tough on cancer. This is the first cancer drug tested while in development for its effect on fertility using a novel, quick in vitro test designed by the scientists.

Quantum computers counting on carbon nanotubes
Carbon nanotubes can be used as quantum bits for quantum computers. A study by physicists at the Technische Universitaet Muenchen has shown how nanotubes can store information in the form of vibrations. Up to now, researchers have experimented primarily with electrically charged particles. Because nanomechanical devices are not charged, they are much less sensitive to electrical interference.

Discovery of first motor with revolution motion in a virus-killing bacteria advances nanotechnology
Scientists have cracked a 35-year-old mystery about the workings of the natural motors that are serving as models for development of a futuristic genre of synthetic nanomotors that pump therapeutic DNA, RNA or drugs into individual diseased cells. Their report revealing the innermost mechanisms of these nanomotors in a bacteria-killing virus -- and a new way to move DNA through cells -- is being published online today in the journal ACS Nano.

Under the skin, a tiny laboratory
EPFL scientists have developed a tiny, portable personal blood testing laboratory: a minuscule device implanted just under the skin provides an immediate analysis of substances in the body, and a radio module transmits the results to a doctor over the cellular phone network. This feat of miniaturization has many potential applications, including monitoring patients undergoing chemotherapy.

New nanomedicine resolves inflammation, promotes tissue healing
Researchers have developed biodegradable nanoparticles that are capable of delivering inflammation-resolving drugs to sites of tissue injury. The nanoparticles, which were successfully tested in mice, have potential for the treatment of a wide array of diseases characterized by excessive inflammation, such as atherosclerosis. The study was published today in the online edition of the Proceedings of the National Academy of Sciences.

Nature: Smallest vibration sensor in the quantum world
Carbon nanotubes and magnetic molecules are considered building blocks of future nanoelectronic systems. Their electric and mechanical properties play an important role. Researchers of Karlsruhe Institute of Technology and French colleagues from Grenoble and Strasbourg have now found a way to combine both components on the atomic level and to build a quantum mechanical system with novel properties. It is reported now in the print version of Nature Nanotechnology journal.
