In 1959, physicist and Nobel prizewinner Richard Feynman set scientists a goal of imaging to a resolution of 0.1 Angstrom - smaller than the radius of an atom. In 2013, researchers working in electron microscopy say we might not ever reach that goal, despite hitting 0.5 Angstroms a few years ago.... why? www.nature.com/...
Should we set limits on what science can probe? Are some areas too questionable to investigate? Nature explores taboo genetics - the genetics of IQ, race, sexuality and violence - and the scientists that have crossed the red line to work on them. A poll asks if you think each of these areas should be off-limits to scientists... www.nature.com/... Nature Publishing Group
Twisty beams of light could boost the traffic-carrying capacity of the Internet, effectively adding new levels to the information superhighway, suggests research published in Science. Internet traffic is growing exponentially and researchers have sought ways to get ever more information into the fibre-optic cables that carry it. Now researchers have successfully squeezed extra data-carrying streams of light into a fibre-optic cable and transmitted it for a record 1.1 kilometres.
