DNA code shapes gold nanoparticles

DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA's code can similarly shape metallic structures. The team found that DNA segments can direct the shape of gold nanoparticles - tiny gold crystals that have many applications in medicine, electronics and catalysis.

Five Hopkins students conduct nanotechnology research in Belgium

Each summer, Johns Hopkins Institute for NanoBioTechnology has funding to support several summer research internships abroad. The International Research Experience for Students program, funded by the National Science Foundation, provides support for students to work with researchers at The Inter-University MircroElectronics Centre (IMEC) in Leuven, Belgium. Students work at IMEC's world-class microfabrication facility and learn to design, fabricate and test a wide range of biomedical devices.

Quantum technologies just round the corner? New studies say it's likely

Researchers have realised that entanglement may not always be necessary, and new examples of technologies that can gain a quantum advantage without entanglement have been discovered over the past few years. A new study has focused on a technology called quantum discord. This phenomenon, far more robust and easily accessible than entanglement, can also deliver a quantum advantage: it could be harnessed to bring quantum technologies within easier reach than expected.

New phenomenon in nanodisk magnetic vortices

The phenomenon in ferromagnetic nanodisks of magnetic vortices - hurricanes of magnetism only a few atoms across - has generated intense interest in the high-tech community because of the potential application of these vortices in non-volatile Random Access Memory (RAM) data storage systems. New findings indicate that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well.
