Quantum brain sensors could enable earlier Alzheimer's diagnosis

A University of Sussex study has demonstrated how a new type of quantum sensor could help doctors catch neurodegenerative diseases like Alzheimer’s earlier. The scanners precisely detect tiny changes in magnetic fields produced by firing neurons.

All-star cast of spacecraft chases solar storm across the Solar System

An all-star cast of spacecraft has teamed up from across the Solar System. After a CME erupted from the Sun in October 2014, its journey through space was tracked by Curiosity, Rosetta, Cassini, New Horizons and possibly even Voyager 2, allowing astronomers to study the phenomenon in detail.

Rosetta spacecraft picks up target comet's mysterious "song"

On the eve of the first landing on comet 67P/Churyumov-Gerasimenko, the European Space Agency (ESA) announced that the unmanned Rosetta orbiter carrying the Philae lander has recorded a "song" emanating from comet.
