The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE).

“I liked how you could combine physics, chemistry and biology into something more applied,” she said. “Engineering also gave me a way to mix my interest in science while actually doing good for the environment.”

In the last decade, researchers in academia and the technology sector have been racing to unlock the potential of artificial intelligence. In parallel with federally-funded efforts from the National Institutes of Health and the National Science Foundation, heavy-hitters such as Microsoft, Facebook and Google are deeply invested in artificial intelligence.
As part of the BRAIN Initiative, many UC Davis investigators are studying the nervous system and developing new technologies to investigate brain function.

UC Davis scientists are taking part in a project to build the new “Frontera” supercomputer at the University of Texas at Austin. Funded by a $60 million grant from the National Science Foundation announced last week, Frontera will be the fastest computer at any U.S. university and among the most powerful in the world.

“Spintronics” holds promise for new types of devices for information processing and data storage, with ones and zeros being stored in the spin state of electrons as well as their electric charge. Such devices could be faster and more energy efficient than current electronics.
Dilute magnetic semiconductors such as manganese-doped gallium arsenide are a promising material for spintronics, said Slavomir Nemsak, staff researcher at the Lawrence Berkeley National Laboratory and former postdoc in the UC Davis Department of Physics, working with Professor Charles Fadley and Adjunct Professor Claus Schneider. They have ferromagnetic properties but are not themselves metals. They are called “dilute” because the dopant makes up a small amount (a few percent) of the semiconductor material.
Digital information may appear to exist as abstract ones and zeroes, flipping effortlessly from one to another. But in fact there is a minimum amount of energy required to run any computation system, regardless of how “energy efficient” are its component parts. A recent paper from Jim Crutchfield and Alex Boyd at the UC Davis Complexity Sciences Center with Dibyendu Mandal at UC Berkeley shows that there is some inescapable friction, or “grit in the gears” between the levels of organization in an information system.
Josh Hihath is trying to fuse biology and electrical engineering and to build new types of electronic memory based on DNA. Hihath, professor in the UC Davis Department of Electrical and Computer Engineering, is principal investigator of a grant just funded by the Semiconductor Synthetic Biology for Information Processing and Storage Technologies (SemiSynBio) program. SemiSynBio is a partnership between the National Science Foundation and the Semiconductor Research Corporation.

A first-ever tissue implant to safely treat a common jaw defect, temporomandibular joint dysfunction, has been successfully tested in animals by researchers from UC Irvine and UC Davis.
“We were able to show that we could achieve exceptional healing of the TMJ area after eight weeks of treatment,” said UCI Distinguished Professor of biomedical engineering Kyriacos Athanasiou, senior author on the study, published Wednesday in Science Translational Medicine. Athanasiou, who joined UC Irvine last year after several years at UC Davis’ Department of Biomedical Engineering, has been working on the condition for nearly two decades.
Spinal injuries are life-changing, and it used to be thought that recovery of limb movement below the injury was impossible. But new research is showing that with the right therapies, the body can find ways to work around spinal injuries. Professor Karen Moxon of the UC Davis Department of Biomedical Engineering talks about her work with rats and how they can recover from injury.
