A Primer on Aerosols

Aerosols, explained
Tiny particles floating in the atmosphere have a much bigger impact on the planet than you might think, and human activity plays a role.
BY ALEJANDRA BORUNDA for National Geographic

THE MOST VIBRANT sunsets, cloud-choked skies, and cough-inducing days all have something in common: They happen because of aerosols, tiny particles that float in the air. Aerosols can be tiny droplets, dust particles, bits of fine black carbon, and other things, and as they float through the atmosphere they change the whole energy balance of the planet.

Aerosols have an outsized effect on the planet’s climate. Some of them, like black and brown carbon, warm the Earth’s atmosphere, while others, like sulfate droplets, cool it. Scientists think that on balance, the whole budget of aerosols ends up cooling the planet slightly. But exactly how much, and how much that…

Face-Scanning Tech Expanding in USA, EU

Fight against facial recognition hits wall across the West
The result is an impasse that has left tech companies largely in control of where and how to deploy facial recognition.

Face-scanning technology is inspiring a wave of privacy fears as the software creeps into every corner of life in the United States and Europe — at border crossings, on police vehicles and in stadiums, airports and high schools. But efforts to check its spread are hitting a wall of resistance on both sides of the Atlantic.

One big reason: Western governments are embracing this technology for their own use, valuing security and data collection over privacy and civil liberties. And in Washington, President Donald Trump’s impeachment and the death of a key civil rights and privacy champion have…

Cave art depicting human-animal hybrid figures hunting warty pigs and dwarf buffaloes has been dated to nearly 44,000 years old, making it the earliest known cave art by our species.

The artwork in Indonesia is nearly twice as old as any previous hunting scene and provides unprecedented insights into the earliest storytelling and the emergence of modern human cognition.

Previously, images of this level of sophistication dated to about 20,000 years ago, with the oldest cave paintings believed to be more basic creations such as handprints.

Twitter Stencils Cause a... twitter (SF)

Twitter ad campaign runs afoul of city vandalism laws

Some BART riders have called a recent Twitter ad blitz around Powell Station “irritating” and “overkill,” but city officials are calling it illegal.

Or at least part of it.

The social media company launched an ad campaign this week in San Francisco and New York City that covered the walls of the station with images of user tweets about Twitter.

All well and good, if potentially annoying for some viewers, but the campaign continued outside with sidewalk chalk stencils extending into the Tenderloin — and that puts it in breach of The City’s vandalism laws, the Department of Public Works said Thursday.

“Our sidewalks are not to be used for commercial purposes, they are not billboards,” said Rachel Gordon, a spokesperson for…

They usually strike at night. Spray can in hand, they scrawl their crude tags on San Francisco’s historic brick facades, business windows and sidewalks.

And when morning reveals the destructive spree of graffiti, the vandals are usually long gone, leaving property owners with a stubborn cleanup job — possibly even a fine.

But thanks to an aggressive new strategy by police and prosecutors, such incidents of vandalism appear to be in decline, according to the latest numbers. Reports of graffiti to 311 have hit an all-time low since the city started tracking the data at the start of 2016.

There were 3,371 such calls in November compared with 7,611 reported during March,…

LILY MOAYERI | MARCH 30, 2018 | LA WEEKLY

The horror show that is parking in Los Angeles is legendary. And parking in West Hollywood takes the nightmare to a whole other level. But Pattern Park, the fourth and most recent of West Hollywood’s micro-parks, is a bright and colorful spot in this dismal landscape.

The park was designed and painted by renowned street artist Chase. His striking patterns, applied using spray paint, exterior latex paint and stencils, decorate the sidewalk surrounding the parking lot on the…

Boulder’s incognito street artist on a life of rebellion

By Emma Murray -  April 19, 2018

Emma Murray | Boulder Weekly

Ten minutes before I turn onto Pearl Street, my phone vibrates. A message: “I forgot to ask… Will you keep my identity a secret?”

I’m en route to a cafe, meeting the person responsible for the impressionist cats, portraits and landscapes sprinkled around Boulder’s downtown electrical boxes, alleyways and forgotten doors — like the tri-color tabby’s face that stares at me from a brick wall on 17th Street.

“Of course,” I reply. Inside, I order a coffee and scan the crowd. What does an incognito graffiti artist…
