In technology news, a team of researchers at the University of California, Irvine, discovered a way to use music to trigger a deadly pathogen release—a finding that showed that people working in negative-pressure rooms could be easily put at risk by criminals using smartphones. Read More

Native to the Western Pacific Ocean and Indian Ocean, the octopus uses the iridescent blue rings on its underlying brown skin to signal to other creatures, camouflage itself and ward off enemies. To mimic this action, the UCI team used wrinkled blue rings surrounding brown circles, sandwiched between a transparent proton-conducting electrode and an underlying acrylic membrane, with another identical electrode underneath.

And a team at the University of California, Irvine, discovered that music could be used to trigger a deadly pathogen release from a negative-pressure room used for biological research. They noted that someone familiar with how pressure controls are used for such rooms could embed a tone in a song playing on a smartphone that would change how the pressure-control fans operate in the room, and thus affect air flow, potentially blowing air out instead of keeping it in.

Inspired by the small but deadly blue-ringed octopus, [UCI] researchers have created a novel technology that rapidly changes color and appearance under various kinds of light, enabling camouflaging and signaling. The tech has potential applications in fields like the military, medicine, and robotics. … “We are fascinated by the mechanisms underpinning the blue-ringed octopus’ ability to rapidly switch its skin markings between hidden and exposed states,” said Alon Gorodetsky, corresponding author of the study.

Cynthia Guidry, who most recently served as deputy executive director of Los Angeles World Airports (LAWA), was today announced as the new director of the Long Beach Airport. … She holds a bachelor’s degree in civil engineering from the University of California, Irvine and a master’s in business administration from Pepperdine University.
