Parasitic Weeds Threaten Tomato Plants on California Farms

At first glance, Orobanche ramosa looks like an interesting blossoming plant, one that could add a unique flair to flower arrangements. But it’s a parasitic weed that attaches to roots, sucks out nutrients and is threatening California’s lucrative $1.5 billion processing tomato industry.

Matter at Extremes: A Question of Scale

In a paper published last week by Physical Review Letters, Jean-Pierre Delplanque, a professor in the Department of Mechanical and Aerospace Engineering and the dean of graduate studies at the University of California, Davis, and a team of researchers from Lawrence Livermore National Laboratory (LLNL) and Sandia National Laboratories, have developed a scaling law to analyze the kinetics of high-pressure, rapid solidification of metastable liquids observed in national laboratory and academic experiments over the past few decades.

New Drone Research Advances Wildfire Monitoring

Typically, the primary indicator of a burgeoning wildfire in California is a plume of hazy, gray smoke wafting through the air, seen by satellites or cameras. The California Department of Forestry and Fire Protection, or CalFire, is alerted, and mitigation and containment efforts ensue.
