Elon Musk Bets Twitter Users Will Like a More Freewheeling Platform
Mr. Musk’s planned changes at Twitter, and the response, will be closely watched. Twitter is smaller and less profitable than other social-media companies. … But Twitter users include media personalities, politicians, activists and tech aficionados who help shape social discourse. “It has influence way beyond its user base and way beyond its valuation, and so we care about it,” said David Kaye, former United Nations special rapporteur focused on free speech and now a [clinical] law professor at the University of California, Irvine.

Russia must account for its war crimes, experts say
Heidi Hardt, [associate] professor of political science at UC Irvine, said the U.S. needs to understand the implications of a nuclear power invading a sovereign state. But any policy decisions should start by addressing the human toll of the atrocities occurring in Ukraine, said Hardt, who is on sabbatical from teaching as she works at the State Department on the Council of Foreign Affairs. “We are truly at a critical juncture right now for U.S. foreign policy,” Hardt said.

Large Hadron Collider Seeks New Particles after Major Upgrade
The newest additions to the LHC are far smaller than their cohort—one new detector could fit snugly in a suitcase. The Forward Search Experiment (FASER) is designed to detect new featherweight particles, such as those connected to the dark sector, and FASERnu is designed to detect well-known particles: neutrinos. … “Roughly speaking, about 90 percent of [the particles] actually pass through a piece of paper held 480 meters away,” says Jonathan Feng, a physicist [and Distinguished Professor of physics and astronomy] at the University of California, Irvine, and co-founder of FASER. “If we made it bigger, we wouldn’t actually increase the event rate too much.”

Study shows fitness competition helps weight loss
Online companies are coming up with their own incentives to keep customers coming back borrowing from techniques found in video games. That’s the subject of a study done by academics, including Behnaz Bojd, an [assistant] professor at the University of California, Irvine specializing in information systems. … “Our data shows the competition only works with the exercise and with dieting it’s backfiring.” … Fitness competitions have already gained prominence on social media platforms like Instagram, Bojd said.

What will the Earth look like if all the ice melted? The answer is terrifying.
Meanwhile, a second, NASA-backed study on the Greenland ice sheet found that at least 74 major glaciers that terminate in deep, warming ocean waters are being severely undercut and weakened. … “It’s like cutting the feet off the glacier rather than melting the whole body,” Eric Rignot, a study co-author and a glacier researcher at NASA’s Jet Propulsion Laboratory and [Earth system science professor at] the University of California, Irvine, told The Washington Post. “You melt the feet and the body falls down, as opposed to melting the whole body. I think this is an example that the current projections are conservative. As we peer below we realize these feedbacks are kicking in faster than we thought.”
