Finding biomarkers for early lung cancer diagnosis

Despite decades of warnings about smoking, lung cancer is still the second-most common cancer and the leading cause of death from cancer in the U.S. Patients are often diagnosed only when their disease is already at an advanced stage and …

Engineering new routes to biochemicals

Living cells can make a vast range of products for us, but they don’t always do it in the most straightforward or efficient way. Shota Atsumi, a chemistry professor at UC Davis, aims to address that through “synthetic biology:” designing …

Wine cork or screwcap? It depends on aging

The winter holidays have brought many occasions to celebrate with wine and notice the variety of closures now being used to seal wines. As the New Year kicks off, you may find yourself wondering which type of closure is the …

New X-ray technique for surfaces

Surfaces are very interesting to material scientists. The reactions that happen at the point where inside and outside meet, and elements interact with other chemicals or radiation, are important for developing new technology for batteries, fuel cells or photovoltaic panels, …

Making oxygen before life

About one-fifth of the Earth’s atmosphere is oxygen, pumped out by green plants as a result of photosynthesis and used by most living things on the planet to keep our metabolisms running. But before the first photosynthesizing organisms appeared about …

Watching the structure of glass under pressure

Glass has many applications that call for different properties, such as resistance to thermal shock or to chemically harsh environments. Glassmakers commonly use additives such as boron oxide to tweak these properties by changing the atomic structure of glass. Now …

Reproducing deep-Earth chemistry

A new pressure cell invented by UC Davis researchers makes it possible to simulate chemical reactions deep in the Earth’s crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid …

Modeling of silicon nanoparticles for solar energy

Silicon nanoparticles embedded in a zinc sulfide matrix are a promising material for new types of solar cell. Computational modeling by Stefan Wipperman, Gergely Zimanyi, Francois Gygi and Giulia Galli at UC Davis and colleagues shows how such a material …

Probing hydrogen catalyst assembly, part II

Biochemical reactions sometimes have to handle dangerous things in a safe way. New work from researchers at UC Davis and Stanford University shows how cyanide and carbon monoxide are safely bound to an iron atom to construct an enzyme that …

UC Davis work leads to FDA action on antibacterial soaps

On Dec. 16, the U.S. Food and Drug Administration called on manufacturers of antibacterial soaps to demonstrate that the anti-microbial agents have added benefit over  washing with soap and water, and that these additives do not pose unacceptable risks. This …
