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...

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...

‘Committed’ CO2 emissions jeopardize international climate goals, UCI-led study finds
“We need to reach net-zero carbon dioxide emissions by midcentury to achieve stabilization of global temperatures as called for in international agreements such as the Paris accords,” said lead author Dan Tong, a UCI postdoctoral scholar in Earth system science. “But that won’t happen unless we get...

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...

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...

Study Warns We Could Melt the Entire Greenland Ice Sheet if We Don't Change Course
Research published Wednesday in Science Advances finds that if emissions continue to climb at their current rate, all of Greenland’s ice could melt by the year 3000, causing sea levels to rise 23 feet and redrawing coastlines around the world. On timescales a bit closer to home, doing nothing to...

Mark Vagins featured in ABC news story about Super-Kamiokande Neutrino Detector Upgrade
This is a neutrino. It’s been hurtling through space for billions of years, emanating from a massive dying star — a supernova — eight times bigger than our Sun. We wouldn’t exist without supernovas — they contain the building blocks of life. So by learning about neutrinos, we can explore our own...

UCI scientists create new class of two-dimensional materials
Irvine, Calif., June 6, 2019 – In a paper published this week in Nature, materials science researchers at the University of California, Irvine and other institutions unveil a new process for producing oxide perovskite crystals in exquisitely flexible, free-standing layers. A two-dimensional...

The Apollo 11 Moon Landing Anniversary Is a Reminder of the Importance of Women in STEM
“When I returned to astronomy after leaving the field for over a decade to pursue acting as a career, I thought I had to downplay and hide my background in the arts. A mentor told me to view my theater background as my superpower. She was right. It totally is! It helps me to communicate the results...

Heart of Lonesome Galaxy is Brimming with Dark Matter
The galaxy, known as Markarian 1216 (abbreviated as Mrk 1216), contains stars that are within 10% the age of the universe — that is, almost as old as the universe itself. Scientists have found that it has gone through a different evolution than typical galaxies, both in terms of its stars and the...
