Simple, ingenious way to create lab-on-a-chip devices could become a model for teaching and research

With little more than a conventional photocopier and transparency film, anyone can build a functional microfluidic chip. A local Cambridge high school physics teacher invented the process; now, thanks to a new undergraduate teaching lab at Harvard's School of Engineering and Applied Sciences (SEAS), students will be able explore microfluidics and its applications.

With chemical modification, stable RNA nanoparticles go 3-D

For years, RNA has seemed an elusive tool in nanotechnology research - easily manipulated into a variety of structures, yet susceptible to quick destruction when confronted with a commonly found enzyme. By replacing a chemical group in the macromolecule, researchers have found a way to bypass RNase and create stable three-dimensional configurations of RNA, greatly expanding the possibilities for RNA in nanotechnology.

Colloidal quasi-crystals discovered

An international research group has discovered colloidal quasi-crystals for the first time. In contrast to the quasi-crystals previously documented, which can only be produced under special laboratory conditions, they are simply structured polymers that evolve through self-assembly. Due to their structural characteristics, they will probably be used in the development of innovative devices in photonics.

10 billion bits of entanglement achieved in silicon

Scientists from Oxford University have made a significant step towards an ultrafast quantum computer by successfully generating 10 billion bits of quantum entanglement in silicon for the first time - entanglement is the key ingredient that promises to make quantum computers far more powerful than conventional computing devices.

NIST advances single photon management for quantum computers

The quantum computers of tomorrow might use photons, or particles of light, to move around the data they need to make calculations, but photons are tricky to work with. Two new papers by researchers working at the National Institute of Standards and Technology (NIST) have brought science closer to creating reliable sources of photons for these long-heralded devices.
