A first-ever tissue implant to safely treat a common jaw defect, temporomandibular joint dysfunction, has been successfully tested in animals by researchers from UC Irvine and UC Davis.
“We were able to show that we could achieve exceptional healing of the TMJ area after eight weeks of treatment,” said UCI Distinguished Professor of biomedical engineering Kyriacos Athanasiou, senior author on the study, published Wednesday in Science Translational Medicine. Athanasiou, who joined UC Irvine last year after several years at UC Davis’ Department of Biomedical Engineering, has been working on the condition for nearly two decades.
Spinal injuries are life-changing, and it used to be thought that recovery of limb movement below the injury was impossible. But new research is showing that with the right therapies, the body can find ways to work around spinal injuries. Professor Karen Moxon of the UC Davis Department of Biomedical Engineering talks about her work with rats and how they can recover from injury.

Teams of undergraduate engineers from UC Davis and nearby colleges and universities will be pulling an all-nighter this weekend, working on using the inspiration or processes of nature to prevent or mitigate natural hazards.
The Center for Bio-mediated and Bio-inspired Geotechnics Design-a-thon runs from 11 a.m. Saturday, April 28 to 3 p.m. on Sunday, April 29 in room 1065, Kemper Hall.
Registration is still open: click here
Student teams will select a natural hazard such as fire, flood, earthquake, tsunami or hurricane, and come up with an engineering solution that is affordable, sustainable, has minimal environmental impact and is equitable for all. There will be cash prizes for first, second and third places.
Neutrophils are the most abundant type of white blood cell. They play a vital role in defending us from infections, by engulfing and destroying bacteria and viruses or cancerous cells. A new study by UC Davis engineering student Emmet Francis, working with Professor Volkmar Heinrich in the Department of Biomedical Engineering, adds to our knowledge of how neutrophils are drawn towards infection sites and how they can attack their targets.
First, Francis and Heinrich looked at how isolated neutrophils respond to chemical messengers called anaphylatoxins. These molecules guide immune cells to their targets but can cause severe illness in excessive amounts.
California’s drive to save water during the drought had a double benefit: it saved a lot of energy as well.
This interactive website shows how California cities and water districts saved energy and water
In April 2015, Governor Jerry Brown mandated a 25 percent cut in urban water consumption in the face of continuing drought. Water suppliers were required to report their progress to the State Water Resources Control Board. Now analysis of those figures by researchers Edward Spang, Andrew Holguin and Frank Loge at the UC Davis Center for Water-Energy Efficiency shows that while the state came within 0.5 percent of the water conservation goal, California also saved 1830 GigaWatt-Hours of energy — enough to power more than 270,000 homes.

On Nov. 16-18, the UC Davis College of Engineering hosted more than 60 engineers from the U.S. and European Union for the National Academy of Engineering’s 2017 Frontiers of Engineering symposium.

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.
