From the article Quantum Light Beams Good For Fast Technology:
The researchers have successfully superposed light beams, which produces a state that appears to be both on and off at once.
Light beams that are simultaneously on and off are vital for the next-generation super computers which should be faster than current computers based on bits, that are either on or off.
Previously, only smaller light particles had been superposed and the group has also proved a quantum physics theory known as Schrödinger's cat.

Astronomers find gaping hole in the Universe from PhysOrg.com
University of Minnesota astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies and gas, as well as the mysterious, unseen “dark matter.” While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all.

Using life's building blocks to control nanoparticle assembly from PhysOrg.com
Using DNA, the molecule that carries life’s genetic instructions, researchers at the U.S. Department of Energy’s Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters.

From the article Scientists hail ‘frozen smoke’ as material that will change world:
A MIRACLE material for the 21st century could protect your home against bomb blasts, mop up oil spillages and even help man to fly to Mars.
Aerogel, one of the world’s lightest solids, can withstand a direct blast of 1kg of dynamite and protect against heat from a blowtorch at more than 1,300C.
Scientists are working to discover new applications for the substance, ranging from the next generation of tennis rackets to super-insulated space suits for a manned mission to Mars.

Nanoreactors for Reaction Cascades from PhysOrg.com
Living cells are highly complex synthetic machines: Numerous multistep reactions run simultaneously side by side and with unbelievable efficiency and specificity. For these mainly enzymatic reactions to work so well collectively, nature makes use of a variety of concepts. One of the most important of these is division into compartments. Enzymes are not only separated spatially, but also positioned in specific locations within the cell.

Quantum analog of Ulam's conjecture can guide molecules, reactions from PhysOrg.com
Like navigating spacecraft through the solar system by means of gravity and small propulsive bursts, researchers can guide atoms, molecules and chemical reactions by utilizing the forces that bind nuclei and electrons into molecules (analogous to gravity) and by using light for propulsion. But, knowing the minimal amount of light required, and how that amount changes with the complexity of the molecule, has been a problem.

Proposed 'Nanomechanical' Computer is Both Old-School and Cutting-Edge from PhysOrg.com
A group of engineers have proposed a novel approach to computing: computers made of billionth-of-a-meter-sized mechanical elements. Their idea combines the modern field of nanoscience with the mechanical engineering principles used to design the earliest computers.
