Are Saturn’s Rings Really as Young as the Dinosaurs?

Are Saturn’s Rings Really as Young as the Dinosaurs?

Previously, planetary scientists had assumed that Saturn’s rings were as old as the solar system itself—about 4.5 billion years old.“Every new exciting result gets challenged,” said Burkhard Militzer, a planetary scientist at the University of California, Berkeley and a co-author of the Science paper.

If You Want a Robot to Learn Better, Be a Jerk to It

If You Want a Robot to Learn Better, Be a Jerk to It

To that end, researchers at the University of Southern California have shown that when working in a simulation, you can give robots “tough love” by trying to knock objects out of their hands, and it’ll actually help them better learn to grasp objects.

A New Gene Helps Explain Why Some People Need Less Sleep

A New Gene Helps Explain Why Some People Need Less Sleep

Fu and her colleague and spouse Louis Ptáček, both at the University of California, San Francisco, had just identified a gene mutation that significantly decreased how many hours someone needs to sleep .

A Molecule Designed By AI Exhibits 'Druglike' Qualities

A Molecule Designed By AI Exhibits 'Druglike' Qualities

The favorable results in cells and mice were a pleasant surprise; he’d expected the AI-generated molecules would require more tweaks and rounds of computations before they found one with potential.“It’s cool to see AI trained to think a little bit like how a medicinal chemist thinks,” says Adam Renslo, a professor of chemical biology at the University of California-San Francisco who also wasn’t involved in the research.

How a Group of Students Built and Launched a Rocket to Space

How a Group of Students Built and Launched a Rocket to Space

A group of undergraduates from the University of Southern California became the first students ever to launch a rocket into space, as WIRED reported last week . but at that point we knew that the rocket had worked and had stayed intact and was still transmitting data.

Inside the Quietly Lucrative Business of Donating Human Eggs

“There's a huge lack of data there to really [allow women] to make informed decisions,” says Dr. Diane Tober, an assistant professor at the University of California, San Francisco, who studies egg donors.

Facebook’s Ad System Might Be Hard-Coded for Discrimination

Facebook’s Ad System Might Be Hard-Coded for Discrimination

A new study from researchers at Northeastern University, University of Southern California, and the nonprofit Upturn finds ad delivery —the Facebook algorithms that decide exactly which users see those ads—may be just as important.

Is the Universe a Hologram? Maybe! This Math Trick Shows How

Is the Universe a Hologram? Maybe! This Math Trick Shows How

There is “tantalizing evidence,” said Xi Dong of the University of California, Santa Barbara, who led the research, that the new model is a piece of “a unified framework for quantum gravity in de Sitter [space].” Dong and co-authors Eva Silverstein of Stanford University and Gonzalo Torroba of the Bariloche Atomic Center in Argentina constructed a hologram of dS space by taking two AdS universes, cutting them, warping them and gluing their boundaries together.

Astronomers Creep Up to the Edge of the Milky Way’s Black Hole

Astronomers Creep Up to the Edge of the Milky Way’s Black Hole

The idea, first proposed in 2005 by Avery Broderick, now at the Perimeter Institute of Theoretical Physics and the University of Waterloo in Canada, and Avi Loeb of Harvard University, would explain why the black hole appears to flare.“It seems like they’ve got something really exciting here,” added astronomer Andrea Ghez, a longtime competitor to the European team at the University of California, Los Angeles.If these rotating flares are due to hot spots in the way that Broderick and Loeb imagined, additional flares will help reveal the black hole’s “spin,” a measure of its rotation.

Seeing hidden worlds under melting ice – Climate Change: Vital Signs of the Planet

Seeing hidden worlds under melting ice – Climate Change: Vital Signs of the Planet

OMG is a multi-pronged effort to map the underwater contours of the Greenland coast, and better understand how warming ocean waters drive melting ice. A giant leap forward came late in 2017, when NASA, the University of California, Irvine and others published high resolution maps of the bedrock and sea floor around Greenland.

Far Out! Worms May Dose Mice With Cannabinoids to Kill the Pain

Far Out! Worms May Dose Mice With Cannabinoids to Kill the Pain

Meaning, your late car payment ain’t got nothing on spending your entire life in an intestine.Researchers at the University of California, Riverside, have found that one nematode worm, Nippostrongylus brasiliensis, appears to boost its odds of survival by dosing its rodent hosts with endocannabinoids, molecules that are known to reduce inflammation.
