An anonymous reader quotes CNET: The early morning hours on the U.S. East Coast might be unusually colorful as NASA plans to produce artificial blue-green and red clouds that may be visible from New York to North Carolina… It’s a test of a new system that helps scientists study the auroras and ionosphere. A NASA sounding rocket (a small, sub-orbital rocket often used in research) will launch from Wallops Flight Facility off the coast of Virginia and release several soda-sized canisters of vapor tracers in the upper atmosphere that may appear as colorful clouds. The tracers use vapors made up of lithium, barium and tri-methyl aluminum that react with other elements in the atmosphere to glow, letting researchers visually track the flows of ionized and neutral particles. It’s a bit like being able to dye the wind or ocean currents to be able to get a visual picture. CNN adds that “If you’re near the eastern U.S. coast, look toward the eastern horizon beginning about 4:30 a.m. The farther you are from the launch location, the lower the clouds will appear on the horizon.” Basically, try to adjust your gaze towards Virginia’s eastern shore — and if you’re not on the east coast, NASA is livestreaming the launch and posting updates on Facebook and Twitter.

NASA Will Create Fake Red And Green Clouds Near Virginia
One of the largest spam operations in the world has exposed its entire operation to the public, leaking its database of 1.37bn email addresses thanks to a faulty backup. From a report: A faulty backup has inadvertently exposed the entire working database of notorious spam operator River City Media (RCM). In all, the database contains more than 1.37 billion email addresses, and for some records there are additional details such as names, real-world addresses, and IP addresses. It’s a situation that’s described as “a tangible threat to online privacy and security.” Details about the leak come courtesy of Chris Vickery from macOS security firm MacKeeper who — with a team of helpers — has been investigating since January. River City Media’s database ended up online thanks to incorrectly-configured Rsync backups. In the words of Vickery: “Chances are you, or at least someone you know, is affected.” The leaked, and unprotected, database is what’s behind the sending of over a billion spam emails every day — helped, as Vickery points out, by “a lot of automation, years of research, and fair bit of illegal hacking techniques.” But it’s more than a database that has leaked — it’s River City Media’s entire operation.

Major cities across northern China choked Monday under a blanket of smog so thick that industries were ordered shut down and air and ground traffic was disrupted. From a report: At least 23 cities issued red alerts for a swath of pollution that has hovered over much of the nation since Friday, China’s Xinhua news agency reported. Alerts are expected to remain in effect through Wednesday. Hospitals set emergency procedures in motion to deal with an influx of breathing-related illnesses. Large hospitals in the port city of Tianjin, less than 100 miles southeast of Beijing, saw a surge in asthma and other respiratory issues, China’s People’s Daily reported. The pollution forced the city to close the highways and caused delays and cancellations for dozens of flights, Xinhua said. Read more of this story at Slashdot. 
An anonymous reader quotes a report from Phys.Org: Using a new satellite-based method, scientists at NASA, Environment and Climate Change Canada, and two universities have located 39 unreported and major human-made sources of toxic sulfur dioxide emissions. A known health hazard and contributor to acid rain, sulfur dioxide (SO2) is one of six air pollutants regulated by the U.S. Environmental Protection Agency. The 39 unreported emission sources, found in the analysis of satellite data from 2005 to 2014, are clusters of coal-burning power plants, smelters, oil and gas operations found notably in the Middle East, but also in Mexico and parts of Russia. In addition, reported emissions from known sources in these regions were — in some cases — two to three times lower than satellite-based estimates. Altogether, the unreported and underreported sources account for about 12 percent of all human-made emissions of sulfur dioxide — a discrepancy that can have a large impact on regional air quality, said Chris McLinden, an atmospheric scientist and lead author of the study. The co-author of the study, Nickolay Krotkov, says quantifying the sulfur dioxide bull’s-eyes is a two-step process that would not have been possible without an improvement in the computer processing that transforms raw satellite observations from the Dutch-Finnish Ozone Monitoring Instrument aboard NASA’s Aura spacecraft into precise estimates of sulfur dioxide concentrations, and the ability to detect smaller concentrations using a new computer program that precisely detects sulfur dioxide that had been dispersed and diluted by winds.

iONiUM writes: The Economist has a story about how bad the air quality is in Beijing. Due to public outcry the Chinese government has created almost 1, 000 air quality monitoring stations, and the findings aren’t good. They report: “Pollution is sky-high everywhere in China. Some 83% of Chinese are exposed to air that, in America, would be deemed by the Environmental Protection Agency either to be unhealthy or unhealthy for sensitive groups. Almost half the population of China experiences levels of PM2.5 that are above America’s highest threshold. That is even worse than the satellite data had suggested. Berkeley Earth’s scientific director, Richard Muller, says breathing Beijing’s air is the equivalent of smoking almost 40 cigarettes a day and calculates that air pollution causes 1.6m deaths a year in China, or 17% of the total. A previous estimate, based on a study of pollution in the Huai river basin (which lies between the Yellow and Yangzi rivers), put the toll at 1.2m deaths a year—still high.” Read more of this story at Slashdot. 
An anonymous reader writes with a link to BBC’s report that [A]uthorities in China have a removed from websites a popular documentary which highlights the country’s severe pollution problem. Under the Dome explains the social and health costs of pollution, and was watched by more than 100 million people online, sparking debates. It was removed just two days after Premier Li Keqiang called pollution a blight on people’s lives. Searching YouTube gives you a pretty good idea of what the Chinese government doesn’t want people to see. Read more of this story at Slashdot. 
Stanford’s Linear Accelerator Laboratory operates the longest particle accelerator of its kind—it’s produced groundbreaking work in particle physics over the decades, as well as several Nobel prizes. But surprisingly, it also played a major role in the early web: By hosting the first web site in the US . It wasn’t much to look at, but that’s not important. Read more…
