Super alloy’s stamina to bear extreme heat and cold shocks scientists
Researchers have uncovered a new remarkable metal alloy that doesn’t crack at extreme temperatures due to kinking, or bending, of crystals in the alloy at the atomic level. Unlike most materials, the new alloy displays impressive strength and toughness at extremely hot and cold temperatures, a combination that seemed nearly impossible to achieve until now.

Survival in the Atacama Desert
The cyanobacteria "didn't need water from the rock, they got it from their surroundings", says David Kisailus, from UC Irvine. "But when they were put under stressed conditions, the microbes had no alternative but to extract water from the gypsum, inducing this phase transformation in the material." Read More

Study: Droughts Are Growing Hotter Under Climate Change
Now, scientists at University of California, Irvine have found that areas experiencing dry conditions are heating up faster than the rest of the country. "We've observed a shift of approximately 0.6 degrees Celsius [1.0 Fahrenheit] between the first and the second half of the 20th century. But if you only include months classified as dry, you see that there's almost double the shift in temperature," said lead author Felicia Chiang, a graduate student researcher in civil and environmental engineering at UC Irvine.

Smart skin sticker could detect asthma attacks before they happen
The device is made using Shrinky Dinks – plastic sheets that shrink to a fraction of their original size when heated. They are popular among children because they can be coloured and cut into shapes before shrinking. … It could be a useful tool for monitoring people with chronic lung conditions, such as asthma and cystic fibrosis, says Michelle Khine at the University of California, Irvine, who led the team. People will use the device by sticking it to their lower ribs.

Spies Can Tell What a 3D Printer is Making by Listening to it
Mohammad Al Faruque of the Advanced Integrated Cyber-Physical Systems lab. "According to the fundamental laws of physics, energy is not consumed; it's converted from one form to another -- electromagnetic to kinetic, for example. Some forms of energy are translated in meaningful and useful ways; others become emissions, which may unintentionally disclose secret information," he explained, in a complicated way of saying making stuff = sound clues. Like, you could fake a chair by listening to the chipping sounds of a carpenter.

Study: Transitioning California Off Gas Could Lower Costs and Prioritize Low-Income Communities
Last week, the California Energy Commission hosted a workshop to dig into Energy and Environmental Economics (E3) and UC Irvine’s latest “Future of Gas” study, which analyzes pathways to a low-carbon buildings sector.

Study: Los Angeles’ major flood risk is much higher than previously thought
When it comes to storm damage, Los Angeles County may not be the first place that comes to mind. But according to a new study, the area’s “hundred-year” flood risk is far greater than what the federal government currently estimates — and a disproportionate danger for Black residents in certain key areas. … And it may not just be L.A.

Study offers new approach for more accurate epidemic modeling
"Standard epidemiological models rely on the presumption of strong mixing between infected and non-infected individuals, with widespread contact between members of those groups," said co-author Tryphon Georgiou, UCI Distinguished Professor of mechanical & aerospace engineering. "We stress, rather, that transmission occurs in geographically concentrated cells.
