Your gut isn’t the only place that harbors a community of microbes. There are also microbiomes coating your skin and most household, industrial, and commercial surfaces. There's even a community hanging out in the lower atmosphere. Scientists in Spain have monitored this airborne microbiome by taking rain and snow samples every two weeks for seven years at a site in the central Pyrenees. The samples were then run through a DNA sequencer to reveal the airborne microbiome. They found that the bacteria, archaea, protists, and fungi all varied predictably by season.
In the wintertime, microbes frequently had marine origins, coming primarily from the Atlantic, although these were mixed in with bugs from forest and other terrestrial sources. Overall, the winter atmospheric microbiome was the most diverse, and that diversity included the highest levels of pathogens in any season.
In the summer the microbiome was more regional, coming from the Mediterranean as well as fresh water, cropland, and cities. There was more pollution in the summer; the scientists monitored atmospheric levels of chemicals, including nitrates and sulphates, in addition to microbes. One of the most abundant and recurring taxa over the seven summers was Ramlibacter, related to a bacterium first isolated in 2011 from meteorite fragments buried in the sands near Tatouine, in Tunisia. It is specifically adapted to live in hot, dry, desert climes, so the researchers suggested that it could be used as a forensic signature for “summertime in Europe—African dust in the air”.

Defra concedes end-to-end testing can throw up challenges as MPs shout into the void
The UK's food and farming department has yet to test six critical IT systems ahead of Brexit and may have to rely on manual workarounds or "unsophisticated" tech, MPs have warned.…
Black holes are… um, black. The point of a black hole is that the force of gravity is strong enough to prevent light from escaping its grasp. But the matter that is being sucked into a black hole is not at all happy about its fate. The matter gets hot and bothered and starts to glow very brightly before it reaches the black hole. This produces what are called luminous accreting black holes.
Most black holes are proud of themselves, sucking down matter right before our very eyes. But others are shy and seem to hide their antisocial behavior, raising questions about whether they were actually there. It turns out that these murderous monsters are hiding behind the gas clouds created by galaxy collisions. It took a serious amount of detective work to penetrate the fog.Introducing the eyewitnesses
Astronomers have long recognized that not everything in the Universe happens slowly. Sure, our Sun will be stable for billions of years, but when things start to go wrong, they go downhill quickly (use your remaining eight minutes wisely). Likewise, when something big gets sucked into a black hole, it sends a last desperate SOS in the form of a bright X-ray flash.

5G is on its way.
Comcast has agreed to pay $700,000 in refunds "and cancel debts for more than 20,000 Massachusetts customers" to settle allegations that it used deceptive advertising to promote long-term cable contracts, Massachusetts Attorney General Maura Healey announced yesterday. "Comcast stuck too many Massachusetts customers with lengthy, expensive contracts that left many in debt and others with damaged credit," Healey said.
The Massachusetts AG alleged that Comcast violated state consumer protection laws by "fail[ing] to adequately disclose the actual monthly price and terms of its long-term contracts for cable services, including failing to disclose to customers that the company could increase the price of certain monthly fees at any point during the long-term contracts."
Comcast advertised a $99 lock-in rate "but did not adequately disclose equipment costs and mandatory monthly fees" that would add to monthly bills, and "failed to adequately disclose that the fees could increase while the customer was locked into the long-term contract," the AG investigation found.
The real thing will, presumably, not be made of wire.
Ford is working with Postmates and Walmart on a pilot program for self-driving grocery deliveries, the companies announced on Wednesday.
"We are exploring how self-driving vehicles can deliver many everyday goods such as groceries, diapers, pet food and personal care items," Ford said in a press release.
The grocery delivery pilot experiment will be based in Miami, where Ford's self-driving car company, Argo, is already testing self-driving vehicles. Ford had been testing self-driving deliveries with Postmates prior to this announcement.

Sound is very much an ephemeral phenomenon. So when acoustician Yuri Lysoivanov wanted to capture the unique acoustics of natural caves, he lugged all his recording equipment to Mammoth Cave in Kentucky to analyze the reverberations and resonances. He described this experience at a meeting of the Acoustical Society of America in Victoria, Canada, earlier this month.
Reverberation is a critical design element, especially for performance spaces. It's not the same as an echo, which is what happens when a sound repeats. Reverb is what happens indoors when sound can't travel sufficient distance to produce those echoing delays. Instead, you get a continuous ring that gradually "decays" (fades).
American audio engineer Bill Putnam was the first person to use "artificial reverb" for commercial recording in the late 1940s with the Harmonicats' "Peg o' My Heart"—achieved by placing a microphone and loudspeaker in the recording studio's bathroom. (Bathroom and subway tiles have excellent reverberation, which is why buskers have their favorite spots in New York City's subway stations.) Today, one of the most popular digital techniques is called convolution reverb, which uses recordings of the acoustics of real spaces to produce highly realistic simulations of those spaces.
