At LIGO, three’s a trend

The third detection of gravitational waves from merging black holes provides a new test of the theory of general relativity.

Hot extra dimensions

The most-cited paper in theoretical particle physics in 2004 was "A large mass hierarchy from a small extra dimension" by Lisa Randall and Raman Sundrum, published in Physical Review Letters in 1999.

City-states of science

Tomorrow's particle physics experiments are redrawing the map for scientific collaboration. Although the field has long been accustomed to large groups of scientists, life in the new CERN collaborations will surely be different.

Starship it's not

"It's funny to see how people react to it. Non-technical people steer wide and won't touch it, while engineers and designers, people you wouldn't think of as given to humor, will stand in front of it until it moves around or put a handkerchief on the wireless camera.

Debbie Harris: Balancing it all

Whether climbing trees with her eight-year-old son Isaac, trying to put a dress on her four-year-old daughter Sonia, or running tests on the MINOS neutrino beam line, Debbie Harris is a problem solver and her mind is always busy. "It's really hard to be a parent," she says.

Two tribes become one

A physicist who has devoted his career to developing linear colliders confronts the decision that changed the global physics community and the focus of his work.

Extra dimensions

In 1998, theorists Lisa Randall and Raman Sundrum met in a coffee shop in Boston to discuss how extra dimensions of space would change the predictions of particle theories.

Solar neutrinos

Deep in the Homestake Gold Mine in Lead, South Dakota, during the early 1970s, Ray Davis monitored a 100,000-gallon tank of perchloroethylene, a chlorine-rich dry-cleaning chemical.

The elusive neutrino

Not only are neutrinos hard to catch, but they also change form as they travel through space. New experiments hope to understand their chameleonic nature.
