The ouroboros (ancient Greek for 'tail devourer') is a motif found in many cultures: a snake biting its own tail, it symbolizes eternity and cycles. Researchers have now constructed a molecular tail devourer, and have named this new class of compound 'ouroborand'. Their tail-biter is a molecular 'machine', which functions as a nanocontainer with a built-in switch that regulates access to the cavity.

Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy.

Transistors, the cornerstone of electronics, are lossy and therefore consume energy. Researchers from the ETH Zurich and EPF Lausanne have developed transistors targeting high switching speeds and higher output powers. The devices can be used more efficiently as conventional transistors, so as to reduce energy consumption and CO2 emissions.
