Helicopters with fuel cells
Fraunhofer Institute for Reliability and Microintegration June 3rd, 2008 In future, an unmanned helicopter will search for people trapped in fallen buildings or investigate contaminated terrain. The mini-helicopter will be powered by a very light fuel cell that weighs only 30 grams and has an output of 12 watts.

Prototype of machine that copies itself goes on show
University of Bath June 4th, 2008 A University of Bath academic, who oversees a global effort to develop an open-source machine that ‘prints' three-dimensional objects, is celebrating after the prototype machine succeeded in making a set of its own printed parts. The machine, named RepRap, will be exhibited publicly at the Cheltenham Science Festival (4-8 June 2008).

“Super paper:” New nanopaper more break-resistant than cast iron
American Chemical Society (ACS) June 4th, 2008 Researchers in Sweden and Japan report development of a new type of paper that resists breaking when pulled almost as well as cast iron. The new material, called "cellulose nanopaper," is made of sub-microscopic particles of cellulose and may open the way for expanded use of paper as a construction material and in other applications, they suggest. Their study is scheduled for the June 9 issue of ACS' Biomacromolecules, a monthly journal.

Argonne research unveiling the secrets of nanoparticle haloing
Argonne National Laboratory June 5th, 2008 A glass of milk, a gallon of paint and a bottle of salad dressing all look to the naked eye like liquids. But when viewed under a microscope these everyday liquids, called "colloids," actually contain small globules or particles that stay suspended in solution.

Multi-particle entanglement in solid is a first
physicsworld.com June 6th, 2008 An international team of physicists has entangled three diamond nuclei for the first time. The development promotes solid-state systems to a rank of quantum systems including ions and photons that have achieved entanglement for more than two particles. Entanglement lies at the heart of fields such as quantum computation and quantum teleportation. At its most basic level, if two particles are entangled a measurement of the state of one reveals something about the state of the other, regardless of the distance separating them. But entanglement is difficult to achieve. It requires quantum states to be manipulated while preventing them from interacting with their environment, which tends to degrade the quantum system into a classical state. Physicists have had some successes, having entangled up to eight calcium ions and up to five photons. So far, however, solid state systems have proved trickier. Now, a team led by Jöerg Wrachtrup of the University of Stuttgart, Germany, has demonstrated that two or three diamond nuclei can be entangled (Science 320 1326). "If we compare the quality of entanglement in our experiments with those [of ions and photons], our results compare favourably," says Wrachtrup. His team includes researchers from the University of Tsukuba, the National Institute of Advanced Industrial Science and Technology, and the Nanotechnology Research Institute, Japan, and Texas A&M University, US.
