The U.S. Department of Energy recently announced $218 million in new grants for “Quantum Information Science” and researchers with the Center for Quantum Mathematics and Physics (QMAP) at UC Davis are among the recipients.
The QMAP initiative at UC Davis is aimed at fundamental research in theoretical and mathematical physics.
Professors Veronika Hubeny and Mukund Rangamani were awarded $348,000 over two years for work on “Entanglement in String Theory and the Emergence of Geometry.” They will explore connections between the nature of spacetime, quantum entanglement and string theory. Entanglement, famously described by Einstein as “spooky action at a distance,” is a phenomenon in quantum physics where the properties of pairs of particles are correlated even when they are widely separated.
Doctoral candidate Philipp Brand and his colleagues at the University of California, Davis, had just finished compiling the genome, or complete set of genetic material of the firebrat — a tiny wingless, nocturnal insect found throughout much of the world — when something surprised him.

There they were–odorant receptor genes, the scent-detecting genes thought to have evolved with winged insects more than 400 million years ago. But this groundbreaking discovery indicates they evolved millions of years earlier.
Scientists are gaining a better understanding of Pierce’s disease and how it affects grapevines. The disease, which annually costs California more than $100 million, comes from a bacterium called Xylella fastidiosa. While the bacterium has been present in the state for more than 100 years, Pierce’s disease became a more serious threat to agriculture with the arrival of the glassy-winged sharpshooter insect, which can carry the bacterium from plant to plant.
Medical research studies involving prison inmates have a bad reputation, but now a group of nutrition researchers proposes to use prisoners to answer a long running question in nutrition: what is the connection between salt intake and health? They recently published their proposal in the journal Hypertension, reported by Gina Kolata in the New York Times.
Arguments over the role of dietary salt in heart health — the “Salt Wars” — have been raging for years. David McCarron, a nephrologist and former research affiliate with UC Davis’s Department of Nutrition is a prominent “Salt Skeptic,” arguing that Americans eat about the same amount of salt now as 40 years ago, and that salt intake in humans is regulated by the brain, not by how much is added to food.
In this month’s episode of Three Minute Egghead, UC Davis graduate student Gabrielle Black talks about collecting samples of ash from neighborhoods burned by last year’s northern California wildfires. The intense heat on a wide range of household items from insulation to electronics may have created new chemical pollutants. Thanks to modern analytic technology, Black plans to search for both known pollutants and new compounds, and compare them to the ashes of burned wild land.
California’s drive to save water during the drought had a double benefit: it saved a lot of energy as well.
This interactive website shows how California cities and water districts saved energy and water
In April 2015, Governor Jerry Brown mandated a 25 percent cut in urban water consumption in the face of continuing drought. Water suppliers were required to report their progress to the State Water Resources Control Board. Now analysis of those figures by researchers Edward Spang, Andrew Holguin and Frank Loge at the UC Davis Center for Water-Energy Efficiency shows that while the state came within 0.5 percent of the water conservation goal, California also saved 1830 GigaWatt-Hours of energy — enough to power more than 270,000 homes.
As the Juno space probe approached Jupiter in June last year, researchers with the Computational Infrastructure for Geodynamics’ Dynamo Working Group were starting to run simulations of the giant planet’s magnetic field on one of the world’s fastest computers. While the timing was coincidental, the supercomputer modeling should help scientists interpret the data from Juno, and vice versa.

“Even with Juno, we’re not going to be able to get a great physical sampling of the turbulence occurring in Jupiter’s deep interior,” Jonathan Aurnou, a geophysics professor at UCLA who leads the geodynamo working group, said in an article for Argonne National Laboratory news. “Only a supercomputer can help get us under that lid.”
A simple method for manufacturing extremely low-density palladium nanofoams could help advance hydrogen storage technologies, reports a new study from the University of California, Davis.

The Molecular Prototyping and BioInnovation Laboratory, or “Biomaker Lab” at UC Davis is a place where students can try out their ideas and develop their own projects in biotechnology. It reflects as “maker culture” that is well-established in engineering, and growing in biological sciences.
