Using a 3D imaging technique called seismic tomography and data gathered from more than 1,000 on- and offshore seismometers, researchers William Hawley, Richard Allen, and Mark Richards have captured a clearer picture of one portion of the earth’s elusive deep structure. It’s a giant, sausage-shaped accumulation of buoyant material beneath the Juan de Fuca Plate—an oceanic plate nearly the size of Michigan. The plate’s western edge runs from Northern California to Vancouver Island, Canada.
Amid rumors that President Donald Trump will soon pull out of the Paris climate agreement that former President Barack Obama signed last year, more than 2,300 faculty from California universities have signed an open letter to the Trump administration calling for sustained action on climate change and urging the president to honor the country’s commitment to reducing greenhouse gas emissions as set forth in the agreement.
L&S congratulates Peter Gao on being named the inaugural postdoc fellow in Heising-Simons' "51 Pegasi b" program! Named after the first exoplanet discovered, 51 Pegasi b Fellows are exceptional scientists who will advance planetary astronomy.
Katherine de Kleer, a current Berkeley doctoral candidate, is also an inaugural fellow. Katherine will do her fellowship at Caltech.
Art Rosenfeld, a Lawrence Berkeley National Laboratory (Berkeley Lab) Distinguished Scientist Emeritus who is also known as California’s “godfather” of energy efficiency and who has been credited with being personally responsible for billions of dollars in energy savings, died Friday at his home in Berkeley, California. He was 90.
In a paper published online last week in the journal Physical Review Letters, the UC Berkeley assistant professor of physics,Norman Yao, describes exactly how to make and measure the properties of such a crystal, and even predicts what the various phases surrounding the time crystal should be — akin to the liquid and gas phases of ice.
The astonishing beauty of galaxies visible from Earth has enchanted humanity ever since our ancestors first gazed into the twinkling night and wondrously beheld them. Some galaxies look like elegant whirling spirals or cosmic frisbees, while others look like elliptical blobs or lumpy irregular clumps smeared across the sky. The variety of galactic shapes prompts questions as old as astronomy: why do galaxies form these characteristic shapes? Can elliptical galaxies become spirals, or vice versa?
One of the rare and brief bursts of cosmic radio waves that have puzzled astronomers since they were first detected nearly 10 years ago has finally been tied to a source: an older dwarf galaxy more than 3 billion light years from Earth.
