Hundreds of thousands of people in Los Angeles could experience at least a foot of flooding during a 100-year disaster, a new scientific study has found, highlighting the hazards of aging infrastructure in America’s second-largest city. This is a much higher estimate of flood exposure in Los Angeles than the one produced by the federal government. … The discrepancy is explained, in part, because the new study takes a more realistic view of the city’s water infrastructure, said the report’s lead author, Brett F.

A team led by researchers at UC Irvine has won a $904,000 grant from the Air Force Office of Scientific Research for a four-year project to uncover the multiscale architectural features and functions of the exoskeletons of two beetle species.

UC Irvine Civil Engineering Professor Brett Sanders, who researches the region’s sand erosion trends and troubles [said], “It will spread out across the coast,” explained Sanders, whose team has measured the coastline and studies wave action that moves sediment. “There will be times it gets pulled offshore. When there’s milder waves, it tends to push it back on shore.

The shallow lake was at its most expansive in recent decades in the late 1990s …. But a 5-year dry spell that began in 1998 was coupled with increasing water diversion for irrigation. “We call it anthropogenic drought,” says Amir AghaKouchak, [professor of civil & environmental engineering], a hydrologist at the University of California (UC), Irvine, who first visited Urmia as a student in 1998. … In the past few years, such worries receded as ample precipitation helped boost lake levels by about 1.5 meters.

Now, [Ron] Davis and other scientists at Stanford and the University of California, Irvine, have created a device that could make diagnosing ME/CFS much simpler. The research was published Monday in Proceedings of the National Academy of Sciences. Known as a “nanoneedle,” the new device picks up on certain changes in electrical signals to identify people with ME/CFS.

Sand helps buffer the coast from storms …. It keeps the waves from digging into the base of coastal bluffs. So what happened to all that sand? The ocean has been sucking up sand faster than it can be replaced, according to Brett Sanders, a professor of civil and environmental engineering at the University of California, Irvine. Besides storm surges and sea-level rise, there’s also an inland side to the problem, he said. “We’ve kind of been slowly starving our coasts of the sediment supply that it needs to be healthy and resilient,” Sanders said.

Global warming is a potent instigator of deadly heat, with research from University of California, Irvine this month finding the probability of a heatwave killing in excess of 100 people in India has doubled due to a 0.5C increase in temperature over the past 50 years.
