The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE).

The goal of the symposium was to facilitate an interdisciplinary transfer of research, ideas and methodologies between outstanding early-career American and European engineers under the age of 45 from industry, universities and other research institutions.
The Center for Integrated Computing and STEM Education at the University of California, Davis, has released version 4 of its popular C-STEM Studio software suite. In addition to free breakthrough tools for teaching math, coding, robotics and making, this major update includes expanded support with textbooks and curriculum for Lego Mindstorms NXT and EV3 robots, Raspberry Pi computers and Arduino control boards as well as Barobo Linkbots. These hardware platforms and related curriculum are seamlessly integrated in C-STEM Studio for learning math with hands-on physical computing and real-world projects.
C-STEM Studio is compatible with robots widely used in school classrooms.

Sometimes, one darn thing leads to another in a series of cascading failures. Understanding the weak points that lead to such cascades could help us make better investments in preventing them.
Professor Raissa D’Souza in the UC Davis College of Engineering studies complex systems and how they can go wrong.
In the Nov. 17 issue of Science, Raissa D’Souza, professor of computer science and mechanical and aerospace engineering at UC Davis, wrote a perspective article about cascading failures that arise from the reorganization of flows on a network, such as in electric power grids, supply chains and transportation networks.

To win the battle against heart disease, cardiologists need better ways to identify the composition of plaque most likely to rupture and cause a heart attack. Angiography allows them to examine blood vessels for constricted regions by injecting them with a contrast agent before X-raying them. But because plaque does not always result in constricted vessels, angiography can miss dangerous buildups of plaque. Intravascular ultrasound can penetrate the buildup to identify depth, but lacks the ability to identify some of the finer details about risk of plaque rupture.

Creating a model of atrial fibrillation with live human heart cells on a chip is the goal of a new $6 million, five-year grant to Professor Steven George at the UC Davis Department of Biomedical Engineering and colleagues at Washington University in St. Louis.
UC Davis biomedical engineer Steven George will grow heart cells on a chip to study atrial fibrillation.
Atrial fibrillation is an irregular heartbeat caused when the heart’s upper chambers beat chaotically and out of sync with the lower chambers, leading to a variety of health problems including stroke and death. Nearly one in ten people over the age of 65 suffer from atrial fibrillation at a cost of around $6 billion.
Applying mathematics to detect chemical weapons, hidden explosives or other threats is the goal of an ongoing project at the UC Davis Department of Mathematics, supported by grants from the National Science Foundation.
Blind deconvolution is a mathematical method to clarify a blurred image without knowledge of the original image, or how it was blurred. Top, original image; bottom, blurred image after blind deconvolution (Original image by Steve Byland).
Threat detection involves math at a range of levels, said Professor Thomas Strohmer, who leads the project. It can include quickly processing large amounts of data, coordinating multiple sensors, or extracting clarity from background noise.

New Instrument Will Enable Discovery in Biology
By Cassaundra Baber
The addition of a ground-breaking microscope to the College of Biological Sciences’ arsenal of research tools will transform the way UC Davis life scientists conduct research, researchers say. The lattice light-sheet microscope — one of approximately 25 of its type in the world — has the potential to revolutionize what is known about the living cell.
“Think about Galileo and his telescope,” said Michael Paddy, scientific coordinator for the Light Microscopy Imaging Facility in the Department of Molecular and Cellular Biology. “His invention changed astronomy and our understanding of our place in the world.”
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)
