Engineers at the University of California, Irvine have invented an end-to-end transmitter-receiver silicon chip that is capable of processing digital signals with significantly greater speed and energy efficiency because of its unique digital-analog architecture. The new wireless transceiver boosts radio frequencies into 100-gigahertz territory, quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications standard.

When hydroelectric power isn’t reliable, people typically turn to fossil fuels, says Brian Tarroja, an energy researcher at the University of California, Irvine. “You do want to build new assets, more renewable energy, more storage, more flexibility and all that stuff,” he says. … That could mean plants that work with lower amounts of water. Even more crucial, he says, is making sure that other renewable energy sources are built up as well. Otherwise, shortcomings in hydropower will continue to mean sliding back into fossil fuel use.

Wetlands constructed along waterways are the most cost-effective way to reduce nitrate and sediment loads in large streams and rivers, according to scientists at the University of California, Irvine; the University of Kansas; the University of Minnesota and other institutions.

Project Scientist …. has partnered with UC Irvine the past three summers and held an expedition last week at the university’s Henry Samueli School of Engineering. “The event was a great opportunity for the girls to dip their toes into STEM and get familiar with all possible career options available to them,” said A. Lili Castillo, outreach co-chairwoman for UCI’s chapter of the Society of Women Engineers.

Find a way to get more than 800 people from Los Angeles to San Francisco in about an hour.

That's the goal for members of the HyperXite team at UC Irvine as they finalize their designs for a pod that would speed through a tube at more than 700 mph, levitated by compressed air.
