Podcast: Intensive Training for Parents Referred to CPS Improves Child Physiology

Traumatic experiences, such as maltreatment as children, can influence how our mind and body react to stressful situations. UC Davis psychologist Paul Hastings and colleagues at the University of Washington have shown that intensive training for parents referred to Child Protective Services can improve physiological reactions to stress in their young children.

Gene Discovery Pushes Back Origins of Insect Sense of Smell

By Kathy Keatley Garvey

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.

New Insight Into Why Pierce’s Disease Is So Deadly to Grapevines

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.

Could Prison Studies End the Salt Wars?

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.

Making an Impact in Research: Advice from Experience, Pitch Slams from Grad Students

Sometimes there’s just too much going on at UC Davis. Today, you could hear from two groups of researchers at very different points in their careers, looking to make an impact and talking about how to have an impact with research.

Today’s UC Davis Research Expo was put on by the Office of Research with the theme “Pathways to Impact”. This afternoon, the Office of Graduate Studies hosted the final UC Davis round of the Grad Slam competition.

A panel of accomplished UC Davis scientists (and one classicist) discuss how to make an impact with your research at the UC Davis Research Expo, April 5, 2018.

Looking for New Pollutants in the Ashes of Sonoma

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 Water-Saving Drive Saved Energy, Too

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.

Supercomputer Simulates Dynamic Magnetic Fields of Jupiter, Earth, Sun

By Becky Oskin

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.”

New Technique Makes Light Metallic Nanofoam

By Becky Oskin

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.

Hear This: Knockout Mice Show Genes Linked to Deafness

Fifty-two newly discovered genes that are critical for hearing have been found by testing gene-modified ‘knockout’ mice. The newly identifed genes will provide insights into the causes of hearing loss in humans. The study published Oct. 12 in Nature Communications was carried out by the International Mouse Phenotyping Consortium (IMPC), which includes the Mouse Biology Program at the University of California, Davis.
