New patent: Template-synthesized DNA nanotubes

A method of forming DNA nanotubes composed entirely or predominantly from DNA that, The methods of the present invention form single layer or multilayer template-synthesized nanotubes where the bulk of the tube is composed of DNA, and the layers are held together by hybridization of complementary DNA strands. The DNA molecules making up these tubes may be varied as desired, and the DNA is capable of being released from the tube.

Logik mit Atomen: das kleinste "Oder" der Welt

Wissenschaftler der Uni Hamburg konnten erstmals ein funktionierendes Spintronik-Logik-Bauteil verwirklichen, das aus wenigen magnetischen Atomen aufgebaut ist. Beim Schalten des realisierten logischen Oder-Gatters ist im Gegensatz zu herkoemmlichen elektronischen Bauteilen kein Stromfluss noetig, da nur die magnetische Ausrichtung der Atome umgeschaltet wird.

Equinox Summit: Energy 2030 - inspiring ingenuity in energy solutions

Flash forward 20 years... What if our best efforts to lower carbon emissions, wean off fossil fuels, and plan for a soaring population weren't enough? Would we ask ourselves why we didn't take action sooner, transforming the ideas from our greatest innovators into the technologies needed to prepare for a more secure and sustainable future?
