This beetle's shell is so diabolically tough it can be driven over. Now we know how
And scientists have just used a suite of tools to discover the physical and mechanical properties that give the diabolical ironclad beetle its incredible fortitude. "The ironclad is a terrestrial beetle, so it's not lightweight and fast but built more like a little tank," said materials scientist David Kisailus of the University of California Irvine.

Temperatures top 110 in Delhi as punishing heat wave builds in India
While this part of the world is no stranger to extreme heat, scientists say conditions have been worsened because of climate change. “Heat waves happen more frequently now and they are spread around throughout the year,” said Amir AghaKouchak, a professor [of civil and environmental engineering and Earth system science], at University of California, Irvine, in an email. “This is the new normal and most likely it will only get worse in the future unless we take serious actions.” [Subscription required, campus-wide access provided by UCI Libraries.

Toyota Invests Long-Term in Hydrogen Production
Toyota has commissioned FuelCell Energy to build a system to make renewable electricity, hydrogen, and water for the car maker’s largest port facility in North America. The project is Toyota’s latest in a series of moves in reach of an ambitious corporate goal: net zero emissions from its operations by 2050. ... FuelCell Energy brought Tri-gen to fruition working with the U.S. Department of Energy, several California agencies, and the University of California at Irvine. Read More

This beetle is practically indestructible. Now scientists know why
"The ironclad is a terrestrial beetle, so it's not lightweight and fast but built more like a little tank," said David Kisailus, a professor of materials science and engineering at the University of California, Irvine and co-author on the study, in a release. … To study the tiny tanks, a member of the research team, Jesus Rivera, captured beetles and brought them back to the lab. First, researchers discovered the beetle's exoskeleton could withstand around 150 newtons of force -- 39,000 times its body weight.

The Risky Business of Predicting Where Climate Disaster Will Hit
“If you see a flood model, how much confidence can you have in the information?” asks Brett Sanders, a civil and environmental engineering professor at [UC] Irvine and a co-author of the study. He and his colleagues sought “to reveal there are significant differences in models trying to characterize the same thing.” Read More

These MIT Researchers Have Developed Silk Capsules To Replace Microplastics
The researchers state that the new process can make use of the low-grade silk that is normally wasted because it has no applications. “This elegant and clever study describes a sustainable and biodegradable silk-based replacement for microplastic encapsulants, which are a pressing environmental challenge,” says Alon Gorodetsky, an associate professor of chemical and biomolecular engineering at the University of California at Irvine, who was not associated with this research.
