Rebirth of the hot

When physicists in Japan discovered a new generation of high-temperature iron-based superconductors earlier this year, the finding prompted a huge surge of interest in these novel materials and rekindled the dream of room-temperature superconductivity, as Hai-Hu Wen explains

Eyeballing the universe

Just over a year ago, the online project Galaxy Zoo was launched. Two of its founders, Chris Lintott and Kate Land, reflect on the story of one of the most innovative astronomy projects out there

Renaissance man

The Italian physicist Edoardo Amaldi, who was born 100 years ago this month, worked in nuclear physics in the Fermi group before the Second World War and, afterwards, contributed to particle physics and to gravitational-wave research. However, he also played a key role in the setting up of CERN and the European Space Agency, and in promoting arms control, as his son Ugo Amaldi explains
