Common Household Materials Can Cool Outdoor Temperatures
By Photonics.com
Using “Scotch tape” and aluminum foil, engineers at UCLA built a passive radiative cooler that lowers outdoor temperatures without electricity or refrigerants. The team’s cooler design exhibits solar reflectance, long wavelength infrared (LWIR) emittance, and optical selectivity that is comparable to leading radiative coolers, the engineers said.

Helmets on before surf’s up: Concussions an increasing concern in a growing sport
By Mark Mester
Derek Dunfee, a former professional big wave surfer and photographer, said he used to ride 50-foot waves. However, the San Diego surfer’s career ended after more than 20 concussions and with him being almost blind in one eye. “There’s a lot of stuff I did that I prepared for these wipeouts, but when you get hit by a 50-foot wave, especially in terms of head trauma and concussions, there’s not much you can do to prepare for that,” Dunfee said.

From oximeters to AI, where bias in medical devices may lurk
By Nicola Davis
Dr Achuta Kadambi, an electrical engineer and computer scientist at the University of California, Los Angeles said Black or Asian people are assumed to have lower lung capacity than white people – a belief he noted may be based on inaccuracies in earlier studies. As a result, “correction” factors are applied to the interpretation of spirometer data – a situation that can affect the order in which patients are treated.

DIY radiative cooler developed to serve as a research standard
By SPIE
The term “greenhouse effect” became part of public lexicon decades ago, thanks to the ongoing discourse on climate change. A natural phenomenon, the greenhouse effect describes how heat from the sun, in the form of radiation, is trapped by gases in the Earth’s atmosphere. But a large amount of radiation is still lost to outer space, because these wavelengths are poorly absorbed by atmospheric gases. These wavelengths constitute long wavelength infrared (LWIR) radiation.

Magnetoelastic material sustainably powers health monitors using body movement
By Dan O’Brien
The future of bioelectronics – including wearables, implantable devices and smart technologies – hinges on the ability to sustainably power devices. A number of approaches for converting biomechanical energy into electricity have been introduced, including piezoelectrics and triboelectrics, which function by deriving charge from compressing or contacting materials. Unfortunately, these techniques’ suboptimal electronic properties and vulnerability to ambient humidity limit their effectiveness.

Coast Guard: Pipeline damage that caused California oil spill likely happened months ago
By Associated Press
A Southern California underwater oil pipeline was likely struck by an anchor several months to a year before a leak spilled tens of thousands of gallons of crude, the U.S. Coast Guard announced Friday. A large vessel of some kind may have struck the massive pipeline, shattering the concrete casing but not necessarily causing the slender crack from which oil spewed last weekend, said Capt. Jason Neubauer, chief of the Coast Guard’s office of investigation and analysis.
California pipeline likely damaged up to a year before spill
By Michael R. Blood, Matthew Brown and Amy Taxin
An underwater oil pipeline off the Southern California coast was likely damaged by a ship’s anchor several months to a year before it ruptured and sent oil spewing into the ocean and then onto some of the area’s best-known beaches, investigators said Friday.

Statisticians Reveal the Number of Serial Killers That Were Never Caught During The 20th Century
By The Physics arXiv Blog
The most prolific modern serial killer, according to Wikipedia, is probably Harold Shipman, a British doctor who probably killed as many as 250 people.
Shipman’s crimes went unnoticed because his victims were mostly elderly and whose deaths were unlikely to raise suspicions. However, researchers have since pointed out that Shipman’s murderous tendencies stick out like a sore thumb if they are viewed through the lens of statistics. Too many of his patients died unexpectedly and this statistical signature could have raised the alarm earlier.

Light computes any linear transformation without a digital processor
By katewinslet
Various forms of linear transforms, such as the Fourier transform, are widely used for information processing in different applications. These transformations are typically implemented in the digital domain using an electronic processor, and the computational speed is limited by the capacity of the electronic chip used, which becomes a bottleneck for large data and image sizes. The solution to this problem is to replace the digital processor with a compatible optical processor and use light to process the information.

Cloud spraying and hurricane slaying: how ocean geoengineering became the frontier of the climate crisis
by Amy Fleming
Tom Green has a plan to tackle climate change. The British biologist and director of the charity Project Vesta wants to turn a trillion tonnes of CO2 into rock, and sink it to the bottom of the sea.
Green admits the idea is “audacious”. It would involve locking away atmospheric carbon by dropping pea-coloured sand into the ocean. The sand is made of ground olivine – an abundant volcanic rock, known to jewellers as peridot – and, if Green’s calculations are correct, depositing it offshore on 2% of the world’s coastlines would capture 100% of total global annual carbon emissions.

This Carbon-Capture Tech Removes CO2 From the Ocean By Making Seashells

Some startups are turning to machines that suck CO2 directly from the air. Others are betting on trees. But a team of scientists from the University of California, Los Angeles, is turning to the ocean instead.

This is probably both a cause and an effect of the September 2020 Executive Order on Combating Race and Sex Stereotyping. The order states that, “…training that promotes race or sex stereotyping or scapegoating…promote[s] divisiveness in the workplace and distract[s] from the pursuit of excellence and collaborative achievements in public administration.”

Long ago, in lands that were always warm, people got ice from the heavens.
At sunset, they poured water into shallow earthen pits or ceramic trays insulated with reeds. All through the night the water would radiate its heat into the chilly void of space. By morning, it turned to ice — even though the air temperature never dropped below freezing.

The other day, as I was driving across the Brooklyn Bridge, the brakes of my car, a twenty-one-year-old Toyota, stopped working. I pressed the pedal. The car kept rolling. I was going slowly enough that I didn’t hit anyone, or anything, but the feeling was nauseating. The emergency brake, thankfully, still worked, and I inched into Manhattan with my hazards on.
Alder-ene-catalyzing enzymes discovered

Eldon Knuth was trapped.
It was November 1944, and U.S. forces were fighting to liberate the heavily fortified French city of Metz from the Nazis.
When Knuth’s battalion attacked the German-held Fort Jeanne d’Arc, he and about 30 other soldiers with the Army’s 95th Infantry Division got stuck behind enemy lines, in the bitter cold, with meager supplies.
