Plastic Fantastic How the Biggest Fraud in Physics shook the scientific world PALGRAVE MACMILLAN 2009. 272 PP. 15.00 26.95 HARDBACK Sometime in 1999, when I was editor of Physics World magazine, I commissioned Bertram Batlogg, then based at the world-famous Bell Laboratories in Murray Hill, New Jersey, to write an article on cuprate superconductors. As I recall, a first draft arrived a few months later, and I replied with some queries and suggestions. I also recall that it took much longer than...

Quantum dots defined in carbon nanotubes are attractive for exploring a wide range of phenomena in fundamental physics. For some of these experiments it is necessary to confine a single electron in a quantum dot, while controlling the height of the barriers on either side of the dot, but this has proved difficult. Now, Gary Steele, Georg Gotz and Leo Kouwenhoven have confined a single electron in a tunable double quantum dot in a nanotube for the first time, and also observed a novel type of...

Nano Lett. doi 10.1021 nl901165f 2009 Nature 459, 73-76 2009 DNA is a natural polymer with nanoscale geometry. It is comprises a backbone of repeated sugar-phosphate units, with one of the four bases adenine A , cytosine C , guanine G or thymine T attached to each sugar. The base-pairing rules A-T and C-G that form the double helix can also be exploited to build self-assembled nanostructures. One promising approach to DNA nanotechnology, introduced by Paul Rothemund in 2006, uses a lengthy...
