Wheat Gene Database is Tool for Improved Yield and Nutrition

By Ann Filmer

Plant scientists and wheat breeders now have a new tool to develop more nutritious and productive wheat varieties: A public online database of 10 million mutations in wheat genes. Scientists at UC Davis and three institutions in the UK created the database, which will allow scientists worldwide to study the function of every gene of wheat. The research will be reported in Proceedings of the National Academy of Sciences this week.

UC Davis Plant Sciences Professor, Jorge Dubcovsky is working to improve the yield and nutritional value of wheat, one of the world's most important crops.

World’s First Total-Body PET Scanner Takes A Big Step Forward

The UC Davis-based EXPLORER consortium, which aims to build a revolutionary total-body PET (positron emission tomography) scanner, has announced the selection of two industry partners to help build the prototype device. They are United Imaging Healthcare America, a North American subsidiary of Shanghai United Imaging Healthcare, and SensL Technologies of Cork, Ireland.

Positron emission tomography, or PET, scanning uses short-lived radioactive tracers to show how organs and tissues are functioning in the body, while magnetic resonance imaging (MRI) and computed tomography (CT) scans mostly show anatomy. PET scans are widely used to diagnose and track a variety of illnesses, including cancer, heart disease and Alzheimer’s disease.

Multivitamins And Early Nurturing Boost Child Development

By Pat Bailey

For all the moms who obediently popped their prenatal vitamins during pregnancy while  wondering if the supplements could actually benefit their babies, an international research group has the answer, and it’s a resounding “yes.”

In fact, in a recent study the researchers discovered children whose mothers took multi-micronutrient supplements during pregnancy were advanced in cognitive abilities by as much as one full year of schooling by age 9-12 years.

The study, conducted in Indonesia and published Jan. 16 in the journal Lancet Global Health, also indicated that other essential ingredients in the recipe for smarter kids include early-life nurturing, happy moms, and educated parents.

Cybersecurity in 2017: What next after the 2016 Election hack?

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.

Modeling Shows How Social Networks Help Animals Survive

By Mike Gil

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?

Gelatin supplements, good for your joints?

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.

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.

SNO+ Neutrino Detector Gets Ready For Run

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.

UC Davis Veterinary Student Shares in Zika Virus Discoveries

By Pat Bailey

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.

LASER Art/Science Series Reboots

By Jeffrey Day

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.laser-logo

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.
