OverviewVacuum arcs are a concern in nearly every vacuum device under electric field; consequently they are present in a very wide range of applica

An idea derived from string theory suggests that dark matter is hidden in an as-yet-unseen extra dimension. Scientists are racing to test the theory to see if it holds up.

Astronomers using the James Webb Space Telescope have peered into the famous SN 1987A supernova remnant and found something special inside.

  Did you know that particle accelerators are also used to treat cancer? That medical imaging has taken great leaps forwards thanks to the crystals and chips developed for particle physics? And that CERN is home to a facility that develops isotopes for medical research? Ever since X-rays were discovered by Wilhelm Röntgen in 1895, physics and medicine have been closely intertwined. Medical imaging and cancer treatments have benefited from developments in particle physics over the years, and th...

BetaVolt’s nuclear battery lasts for decades, but you won’t see one in your next iPhone—powering a mobile device would require a cell the size of a yak.

There’s energy in Bend’s water system that could power hundreds of homes — if the city seizes the opportunity.

As winter bids farewell, the recommissioning of CERN’s accelerator complex gathers pace, with the scientific community eagerly awaiting particle beams in their experiments. Following the traditional winter break (called the “year-end technical stop” (YETS)), the Linear accelerator 4 (Linac4) is the first machine to resume beam operation, followed by the downstream machines: the Proton Synchrotron Booster (PSB), Proton Synchrotron (PS), Super Proton Synchrotron (SPS) and Large Hadron Collid...

The Electrifiers, in collaboration with the EVTown Steering Committee, aim to educate the community about the benefits of electric vehicles and promote Bloomington-Normal as the EV capital of the Midwest.

AEgIS is one of several experiments at CERN’s Antimatter Factory producing and studying antihydrogen atoms with the goal of testing with high precision whether antimatter and matter fall to Earth in the same way. In a paper published today in Physical Review Letters, the AEgIS collaboration reports an experimental feat that will not only help it achieve this goal but also pave the way for a whole new set of antimatter studies, including the prospect to produce a gamma-ray laser that would all...

I’ve read biographies of highly creative, original artists and have observed a similarity in their character and temperament. They make poor husbands and fathers. They are highly self-absorbed, encapsulated and
