Soil Actually Has a Microbiome
Gut bacteria have been getting a lot of attention lately (yogurt, anyone?) but it turns out the soil in your own back yard is teeming with microbial life. According to Kate Scow, a professor of soil science and microbial ecology at UC Davis, a quarter teaspoon of soil can easily contain a billion bacterial cells. And she estimates there can be 10,000 to 50,000 different taxa of microbes in a single teaspoon. Soil is one of the most complex and diverse ecosystems on the planet, and it is one that is essential for human life through all the functions it provides: the breakdown of organic materials, food production, water purification, greenhouse gas reduction, and pollution cleanup, just to name a few.
Compounds Could Be Basis For Devices That Turn Waste Heat Into Electricity
Cage-like compounds called clathrates could be used for harvesting waste heat and turning it into electricity. UC Davis chemists just discovered a whole new class of clathrates, potentially opening new ways to make and apply these materials.
UC Davis chemists discovered a new class of clathrates that break the four-bond rule. The discovery was featured on the cover of the journal Angewandte Chemie (Wiley)
Where do honey bees come from? A new study from researchers at the University of California, Davis and UC Berkeley clears some of the fog around honey bee origins. The work could be useful in breeding bees resistant to disease or pesticides.

UC Davis postdoctoral researcher Julie Cridland is working with Santiago Ramirez, assistant professor of evolution and ecology at UC Davis, and Neil Tsutsui, professor of environmental science, policy and management at UC Berkeley, to understand the population structure of honey bees (Apis mellifera) in California. Pollination by honey bees is essential to major California crops, such as almonds. Across the U.S., the value of “pollination services” from bees has been estimated as high as $14 billion.

In a universe with billions upon billions of planets, narrowing the search for extraterrestrial life is no mean feat. One approach seeks analogs of otherworldly conditions here on Earth, and characterizes the mineralogy, geochemistry and biology of these areas.

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.

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?

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.
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.

On October 5th, two scientists from the UC Davis Museum of Wildlife and Fish Biology joined a multi-national team of researchers to conduct biodiversity surveys on the island of New Britain, Papua New Guinea.

California’s coastal redwoods are one of the state’s most prominent icons, drawing more than 2 million visitors a year. Another prominent icon? Fog, winding its way across the coast and through the trees. Climate change may be impacting both of them.
Climate change may affect the fog that waters California’s iconic coastal redwoods.
While coastal redwoods typically get plenty of water during the winter, fog helps them get through the summer. But fog is on the decline. What that means for the coastal redwoods in currently unclear.
