The challenge with detecting dark matter is that the signal will probably be incredibly small – perhaps only a couple of particles per day. So it would be really easy to be fooled by some other signal, such as lead-210, which is radioactive. Dr Anton Wallner is testing the crystals that will be used...

by Rebeka Selmeczki If you’ve ever walked into a shop selling Australian merchandise, you will have noticed one of the nation’s most iconic symbols, the Sydney Harbour Bridge, stamped across clothing and shot glasses.   The 92-year-old metal arch, which in its early days was called...

Physicists have devised a way to combine an atomic magnetometer with a gyroscope, using a pulsed laser system and a simple mixture of gases. The new technique will not only be a radical improvement for precision measurements of rotation, but has the potential to be a powerful tool in the search for exotic...

A random conversation between physicists from different areas has led to a new ultrasensitive device to search for dark matter. The device is inspired by an instrument designed for mitigating noise in gravitational wave detectors, and will be sensitive to extremely light dark matter particles, around...
