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.

Applications like Facebook and Twitter show us, on a daily basis, the power of social networks to influence individual behavior. While wild animals do not surf the web, they are connected with other individuals in shared landscapes, and “share information” through their behavior. But how does this information affect surrounding animals?
The formation of multi-species groups, such as these fish feeding on a coral reef, may be fostered by social information sharing. (Heather Hillard)
A new study from Keith Baar’s Functional Molecular Biology Laboratory at the UC Davis College of Biological Sciences and the Australian Institute of Sport suggests that consuming a gelatin supplement, plus a burst of intensive exercise, can help build ligaments, tendons and bones. The study is published in the January issue of the American Journal of Clinical Nutrition.
Connective tissue and bone injuries are common in both athletes and the elderly, and interfere with peoples’ ability (and enthusiasm) for exercise, whether they are an elite athlete or just trying to lose weight and maintain fitness and flexibility. Steps that can prevent injury and enhance recovery are therefore of great interest.
Event Includes Horse Therapies For First Time

Four UC Davis researchers with expertise in the application of stem cell science for therapies in human or veterinary medicine are slated to speak during the World Stem Cell Summit in Palm Beach, Florida, Dec. 6-9.

This will be the 12th consecutive year that the summit has brought together scientists, physicians and veterinarians, industry representatives and patient advocates from around the world to share medical breakthroughs in stem cell research, also known as regenerative medicine.

Not a still from a science fiction movie, but the SNO+ neutrino detector being filled with very pure water prior to starting operations. Located over a mile underground in a mine in Ontario, Canada, the SNO+ detector consists of an acrylic sphere 12 meters in diameter filled with 800 tonnes of scintillation fluid, floating in a bath of ultrapure water surrounded by 10,000 photomultiplier tubes that will detect flashes of light from passing neutrinos.

Hannah Laurence, a third-year student in the UC Davis School of Veterinary Medicine and a Howard Hughes Medical Institute fellow, had the privilege of doing biomedical research during the past year in the laboratory of Professor Jeff Kieft at the University of Colorado School of Medicine.
UC Davis veterinary student Hannah Laurence studied Zika virus through a HHMI fellowship.
Recently, the Kieft lab announced in the journal Science discovery of the molecular process used by the Zika virus to “hijack” the cells that it infects and potentially how the virus makes molecules that are directly linked to disease.

A series at UC Davis that brings together art and science restarts with a new format, location, time and leadership. The Leonardo Art, Science, Evening Rendezvous (LASER) will be re-launched Nov. 10 at 6 p.m. in the Art Annex room 107.
Free and open to the pubic, LASER at UC Davis is being co-directed by Timothy Hyde, assistant professor, Department of Art and Art History, and Jiayi Young, assistant professor, Department of Design.

In the latest episode of the Three Minute Egghead podcast, UC Davis astronomer Marusa Bradac explains why she’s looking towards the beginning of time to find the furthest, faintest object in the universe, and how a gigantic lens in the sky can help.

In the latest episode of the Three Minute Egghead podcast, Ilias Tagkopoulos talks about a computer model that predicts the metabolism of the bacteria Escherichia coli. While E. coli might be one of the most-studied organisms both in labs and as a cause of disease, there is still much we don’t know about it, he notes.
Tagkopoulos and his team spent two years pulling together all the data they could find on E. coli, from DNA sequences to metabolism, and assembling it into a single database. They then used computer clusters and the Blue Waters supercomputer to create their model. You can access their data here.

For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and will improve our understanding of environmental change in Earth’s past.
Foraminifera are marine plankton with complex shells. The shells of dead forams in ocean sediments form a record of climate hundreds of millions of years into the past.
Led by researchers from the University of California, Davis and the University of Washington, with key support from the U.S. Department of Energy’s Pacific Northwest National Laboratory, the team examined an organic-mineral interface where the first calcium carbonate crystals start to appear in the shells of foraminifera, a type of plankton.
