2016 saw an unprecedented use of cyberattacks during a U.S. presidential election. According to the U.S. Department of Homeland Security and the Office of the Director of National Intelligence, the Russian government directed theft of emails and release of information in an apparent attempt to influence the election.
What does this mean for the coming year? I asked Professors Karl Levitt, Matt Bishop, Hao Chen, and Felix Wu of the UC Davis Computer Security Laboratory for some thoughts about cybersecurity in the wake of the 2016 election hack. Here’s what they had to say.
With the third and final debate over, those voters who haven’t yet made up their minds will be focusing on their choice for President. But what do the woolly bear caterpillars of Bodega Bay have to say about the election?

The caterpillars shot to fame a few months ago when UC Davis graduate student Eric Lo Presti pointed out in a blog post that cycles in the caterpillar population tracked with the fortunes of political parties in presidential election years. Going back as far as 1984, Democrats won the White House in years when the caterpillars were abundant in March, and Republicans when the caterpillars were less prolific.
Our species, Homo sapiens, left Africa earlier than previously thought and our diverse cultures have been heavily influenced by geography, according to a recent review by Alexander (Sandy) Harcourt, professor emeritus of anthropology at the University of California, Davis.
The paper grew out of a keynote address to a National Academy of Sciences colloquium in Irvine earlier this year on comparative phylogeography, the study of the geographic distribution of species (Watch a video of Harcourt’s lecture below).
Al Capone’s network drew in thousands of people through activities both legal and illegal.
The Prohibition era, from 1920 to 1933, is remembered as a time when organized crime flourished in the U.S., and no name is more notorious than Al Capone in Chicago. But Capone’s organization didn’t operate in a vacuum: he had clients, suppliers, associates and acquaintances both legitimate and not so much, forming a vast network throughout the city.
We’re adding a new element to the Egghead blog this month with Three Minute Egghead, a podcast about research at UC Davis. While we figure out a few details about RSS feeds and XML, I’ll be posting these audio files to the Egghead blog, usually with an accompanying blog post.
Our first piece is about two UC Davis computer scientists who are using data from the open-source programming website GitHub to learn about coder’s work habits and in particular, how multitasking affects productivity.
Study author Bogdan Vasilescu will be presenting the study at the International Conference on Software Engineering in Austin, Texas tomorrow, May 20.
Global carbon dioxide emissions are triggering permanent changes to ocean chemistry along the West Coast. Failure to act on this fundamental change in seawater chemistry, known as ocean acidification, is expected to have devastating ecological consequences for the West Coast in the decades to come, warns a multistate panel of scientists, including two from UC Davis Bodega Marine Laboratory.
Their report, issued this week, urges immediate action and outlines a regional strategy to combat the alarming global changes underway. Inaction now will reduce options and impose higher costs later, the report said.

How many projects can you work on at the same time, before losing efficiency? There are many reasons to get involved in multiple projects – impress your boss, gain personal satisfaction, help out colleagues or just because you’re interested. But at some point, there must be one project too many.
“There is a limit,” said Bogdan Vasilescu, postdoctoral researcher in the DECAL lab at the UC Davis Department of Computer Science. “Multitasking fills time that’s otherwise unused, but there is a limit at four or five projects in a week.”
Within just a few years, we’ve got used to controlling devices by swiping, scrolling or tapping our fingers on a touch screen. But soon you might not even have to touch anything at all to check your email or play a video – just wave your hand in the air, thanks to ultrasonic technology from Chirp Microsystems, a startup company founded in 2013 by researchers from UC Davis and UC Berkeley.
Chirp’s technology is “disruptive” in the ultrasound area, said David Horsley, professor of electrical and computer engineering at UC Davis and co-founder of the company. Chirp’s ultrasound transducers are smaller and operate with much lower power needs than any currently available.
College students in the STEM fields could see sizable savings thanks to a $600,000 grant awarded to an open source textbook project developed at the University of California, Davis.
The ChemWiki project recently received $600,000 from the National Science Foundation to support further expansion of its open source textbooks into fields including statistics, math, geology, physics, biology and solar energy.
Digital course materials are steadily climbing in use in response to textbook cost concerns, according to an annual survey released in July by the National Association of College Stores. In August, the University of Maryland announced plans to completely eliminate print textbooks this academic year.
Clinical trials are testing whether oxytocin, sometimes called the “love hormone” for its role in intimacy and social bonding, has potential as a treatment for anxiety, depression and post-traumatic stress disorder. New research by behavioral neuroscientists Michael Steinman, Brian Trainor and colleagues at UC Davis suggests oxytocin may have different effects in men and women—and in certain circumstances the hormone may actually trigger anxiety.
In a series of experiments at the UC Davis Department of Psychology, the team administered doses of oxytocin with a nasal spray to male and female mice. Some of the mice were bullied by an aggressive mouse, an experience that reduces motivation to associate with unfamiliar mice. Consistent with previous studies, oxytocin increased the motivation for social interaction in stressed males.
