Five mysteries the Standard Model can’t explain

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and accurate in its predictions. It math... Continue reading

Studying the stars with machine learning

To keep up with an impending astronomical increase in data about our universe, astrophysicists turn to machine learning. Kevin Schawinski had a problem. In 2007 he was an astrophysicist at Oxford University and hard at work reviewing... Continue reading

Looking for dark matter using quantum technology

Fermilab scientists are harnessing quantum technology in the search for dark matter. For decades, physicists have been searching for dark matter, which doesn’t emit light but appears to make up the vast majority of matter in the unive... Continue reading

Progress in plasma wakefield acceleration for positrons

Three new studies show the promise and challenge of using plasma wakefield acceleration to build a future electron-positron collider. Matter is known to exist in four different states: solid, liquid, gas or—under circumstances such as... Continue reading

The 3-ton ruler

A specialized measuring machine at SLAC is helping scientists build precise detectors for the ATLAS experiment. When physicist Katy Grimm and her students began using SLAC National Accelerator Laboratory’s coordinate measuring machine... Continue reading

2018 Photowalk winners announced

Photographers from Italy, the UK and Canada won professional and public votes. From deep under the North Sea to the outskirts of Rome and the Canadian shores of the Pacific, the winning images from the 2018 Global Physics Photowalk co... Continue reading

Life as an accelerator operator

Behind some of the world’s biggest scientific instruments are teams with a set of skills you can’t find anywhere else.  One Friday night in March, accelerator operator Alyssa Miller was chatting with fellow staff members in the rec ce... Continue reading

How not to be fooled in physics

Particle physicists and astrophysicists employ a variety of tools to avoid erroneous results. In the 1990s, an experiment conducted in Los Alamos, about 35 miles northwest of the capital of New Mexico, appeared to find something odd. ... Continue reading
