Two astronauts aboard the ISS conducted their fourth and final spacewalk to finish a series of repairs aimed at extending the functioning of a cosmic ray detector attached to the spacecraft.
Decades ago, Armenian scientists built a high-elevation trap to catch and study cosmic rays. Physics has mostly moved on, but the station persists—a ghost observatory with a skeleton crew.
A growing suite of computational instruments is helping scientists determine how fast local concentrations of dark matter move, which in turn could help them cut in on the dance of dark matter particles.
3D chips—smaller and more powerful than their 2D counterparts—are beginning to make an impact in industry. Now, Fermilab is working with industrial partners to fabricate prototype 3D chips for use in science.
At the heart of many particle physics experiments sits a device with a catchy name: the time projection chamber. With an important job and a storied history, TPCs have a special place in particle physics.
Serge Haroche and David Wineland, who opened a new era of research by building particle traps and experimenting with individual particles without destroying them, were honored with the 2012 Nobel Prize in physics.
