Finding New Forces with Old Techniques 

Interactions predicted by beyond-standard-model theories could be detected using a variation on Mössbauer spectroscopy, according to a new proposal. - Marric Stephens - APS Physics - December 24th 2020.


Nobel Prize: Facing the Reality of Black Holes Three scientists were recognized for proving that gravitational collapse can lead to a black hole and for observing the supermassive black hole at the center of our Galaxy - Michael Schirber - APS News - October 2020


A Few Qubits Go a Long Way  The right combination of quantum and classical computations allows for accurate quantum chemistry simulations using surprisingly few qubits - Marric Stephens - APS News - January 2020


Directly Measuring an Entangled State Researchers have directly measured the components of a nonlocal, entangled wave function, rather than relying on indirect tomographic or reconstructive techniques - David Starling - APS News - October 2019


Unified Theory - APS Physics History - Einstein’s fruit-less quest Albert Einstein spent the last thirty years of his life on a fruitless quest for a way to combine gravity and electromagnetism into a single elegant unified theory - Ernie Tretkoff - APS News - December 2005


World Bee Day: the buzz around Imperial’s research - To mark World Bee Day, we take a look back at Imperial’s un-bee-lievable research into these pollinating insects. - Joanna Wilson - Imperial College - May 2019
