Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians from the University of California, Davis, provide mathematical proof that instabilities inherent in the Einstein-Euler equations imply that the current model of the expanding universe is not viable.

When Carson Jeffres looks at the Yolo Bypass, he sees much more than a heavily trafficked strip of I-80 cutting across land meant for water overflow and agriculture. He sees an ecosystem amidst transformation, one integral to making California, as Jeffres calls it, a “salmon society.” Jeffres shared this vision of California as a salmon society with a packed house at G Street WunderBar for the May edition of the Davis Science Café.

Chemistry graduate student Cocoro Nagasaka works at the interface of environmental and energy sciences. And now he’s continuing his research at the Lawrence Livermore National Laboratory, or LLNL, through the prestigious U.S. Department of Energy’s Office of Science Graduate Student Research (SCGSR) program.

When her ovarian tumor symptoms were misdiagnosed, UC Davis researcher Elizabeth Neumann trusted her instincts and it changed the course of her work. Now, she’s using advanced imaging and mass spectrometry to improve early detection of ovarian cancer, while also speaking out about the challenges women face in healthcare.

While almost the complete inverse of astronomy and cosmology, fields concerned with the largest objects in our universe, particle physics aims to answer similar questions but from a different vantage. Matthew Citron discusses how particle physicists like himself use particle accelerators to search for dark matter.
