Aug 07, 2019 ALMA Dives into Black Hole’s ‘Sphere of Influence’
What happens inside a black hole stays inside a black hole, but what happens inside a black hole’s “sphere of influence” – the innermost region of a galaxy where a black hole’s gravity is the dominant force – is of intense interest to astronomers and can help determine the mass of a black hole as...
Aug 07, 2019 Parts of Alaska Have No Sea Ice For the First Time Ever As Temperatures in the Region Hit Record Highs
Compared to all other recorded years of research, this August has the lowest levels of arctic sea ice ever, according to Mark Serreze, the director of the National Snow and Ice Data Center (NSIDC). “Basically, if you look at Point Barrow — the northernmost point of Alaska — there’s probably no sea...

Jul 29, 2019 UCI, JPL glaciologists unveil most precise map ever of Antarctic ice velocity
Published today in a paper in the American Geophysical Union journal Geophysical Research Letters, the map is 10 times more accurate than previous renditions, covering more than 80 percent of the continent. “By utilizing the full potential of interferometric phase signals from satellite synthetic-...
Jul 26, 2019 Physical Sciences professors sweep 2019 Academic Senate awards for research
Professors Eric Rignot, Tim Tait and Jenny Yang have been named recipients of the 2019 Academic Senate awards for research making the UCI School of Physical Sciences the only school on campus to win awards in the research category. These awards are conferred by the Senate on a faculty member who...
Jul 26, 2019 Europe’s heat wave is about to bake the Arctic
It’s what this system, characterized by a strong area of high pressure aloft — often referred to as a heat dome — will do to the Arctic that has some scientists increasingly concerned. Temperatures in parts of Scandinavia will reach into the 90s or higher, on the heels of an intense heat wave in...
Jul 25, 2019 Extremely powerful cosmic rays are raining down on us. No one knows where they come from.
You may think the greatest, most perplexing mysteries of the universe exist way out there, at the edge of a black hole, or inside an exploding star. No, great mysteries of the universe surround us, all the time. They even permeate us, sailing straight through our bodies. One such mystery is cosmic...
Jul 02, 2019 Loss of deep-soil water triggered forest die-off in Sierra Nevada
Between 2012 and 2015, very little rain and snow fell on California. Aquifers shrank and the land dried out. In 2015 and 2016, the worst drought in a century hit. Temperatures soared. The combination of stressors was too much for the trees of the Sierra Nevada -- large numbers of trees died. New...
Jul 01, 2019 Existing power plants and vehicles have already consigned us to unsafe global warming
The Paris Agreement signed in 2015 implored governments around the world to take significant steps to limit global warming, with signees pledging to keep global temperatures from rising 2° C (3.6° F) above pre-industrial levels this century. More ambitiously, the agreement encouraged countries to...
Jul 01, 2019 UCI, UC Merced: California forest die-off caused by depletion of deep-soil water
“In California’s mixed-conifer mountain forests, roots extend from five to 15 meters deep, giving trees access to deep-soil water,” said co-author Michael Goulden, UCI professor of Earth system science. “This is what has historically protected trees against even the worst multi-year droughts.” But...
