World record: Calculations with 14 quantum bits

Quantum physicists from the University of Innsbruck have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the scientists have not only come closer to the realization of a quantum computer but they also show surprising results for the quantum mechanical phenomenon of entanglement.

Nanoparticles shorten roundworms' lives

Even though nanoparticles are increasingly entering the environment, scientists still have a lot to learn about their biological effects. Now Chinese researchers have found that exposure to cerium dioxide nanoparticles shortens the lifespan of the roundworm Caenorhabditis elegans.

Biological molecules select their spin

Do the principles of quantum mechanics apply to biological systems? Until now, both biologists and physicists have considered quantum systems and biological molecules to be like apples and oranges. But new research definitively shows that a biological molecule - DNA - can discern between quantum states known as spin.

Microstructures innovation recognized as industry "game-changer"

"Industry is eager to harness the potential of micro-technology, but has been unable to do so for most consumer products because of the high manufacturing cost," explained William P. King, a professor and Willett Faculty Scholar in the Department of Mechanical Science and Engineering."Our low-cost, scalable micro-manufacturing technology changes the game."

Microreactors: Small scale chemistry could lead to big improvements for biodegradable polymers

Using a small block of aluminum with a tiny groove carved in it, a team of researchers is developing an improved "green chemistry" method for making biodegradable polymers. Their recently published work is a prime example of the value of microfluidics, a technology more commonly associated with inkjet printers and medical diagnostics, to process modeling and development for industrial chemistry.

Real-time monitoring of atomic force microscope probes adjusts for wear

Scientists at the National Institute of Standards and Technology (NIST) have developed a way to measure the wear and degradation of the microscopic probes used to study nanoscale structures in situ and as it's happening. Their technique can both dramatically speed up and improve the accuracy of the most precise and delicate nanoscale measurements done with atomic force microscopy (AFM).

Fast-recharge, lithium-ion battery could be perfect for electric cars

The next-generation battery, like next-generation TV, may be 3-D, scientists reported at the 241st National Meeting and Exposition of the American Chemical Society (ACS). They described a new lithium-ion (Li-ion) battery, already available in a prototype version, with a three-dimensional interior architecture that could be perfect for the electric cars now appearing in auto dealer showrooms.

The first non-Ttivial atom circuit: Progress towards an atom SQUID

Researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland have created the first nontrivial "atom circuit", a donut-shaped loop of ultracold gas atoms circulating in a current analogous to a ring of electrons in a superconducting wire.
