Cluster takes shape
The Rumba and Tango satellites were sent into space on board a French-Russia launcher. Over the next week they will rendezvous with the Salsa and Samba satellites that were launched on July 16. The fo...
New planets and star birth in Manchester
A team from the University of Colorado at Boulder will present evidence for what it believes is the youngest massive star cluster ever detected in the Milky Way. It contains about 100 type-O stars, th...

New life for Schrödinger’s cat
When the formalism of quantum mechanics is applied to experiments involving microscopic objects such as electrons, we often find that the resulting description assigns finite probability amplitudes to...

Strength is weakness on the Internet
In a ‘scale-free’ network of many interconnected nodes, like the Internet, most of the nodes are connected to a relatively small number of other nodes. Only a very small minority have a la...
Tau neutrino identified at last
The DONUT team fired an intense beam of neutrinos, which they expected to contain tau neutrinos, at a target consisting of iron plates with layers of emulsion sandwiched between them. One in a million...
Sir Mark Oliphant dies
Oliphant was born in Adelaide in 1901 and attended the local university before going to Cambridge University in 1927, where he worked on nuclear physics experiments with Ernest Rutherford. In 1937 he ...
Microscopy: two lasers are better than one
Stefan Hell and co-workers at Gottingen have adapted a technique known as fluorescence microscopy. In this form of microscopy the specimen is irradiated at a wavelength which excites either natural or...
