'New Study Shows Microplastics Turn Into "Hubs" for Pathogens, Antibiotic-Resistant Bacteria
It's estimated that an average-sized wastewater treatment plant serving roughly 400,000 residents will discharge up to 2,000,000 microplastic particles into the environment each day. Yet, researchers are still learning the environmental and human health impact of these ultra-fine plastic particles[...] found in everything from cosmetics, toothpaste and clothing microfibers, to our food, air and drinking water.
[...] researchers found certain strains of bacteria elevated antibiotic resistance by up to 30 times while living on microplastic biofilms that can form inside activated sludge units at municipal wastewater treatment plants.
[...] "These wastewater treatment plants can be hotspots where various chemicals, antibiotic-resistant bacteria and pathogens converge and what our study shows is that microplastics can serve as their carriers, posing imminent risks to aquatic biota and human health if they bypass the water treatment process."
"Most wastewater treatment plants are not designed for the removal of microplastics, so they are constantly being released into the receiving environment," [...] "Our goal was to investigate whether or not microplastics are enriching antibiotic-resistant bacteria from activated sludge at municipal wastewater treatment plants, and if so, learn more about the microbial communities involved."'

'One of America's $135.8 Million Fighter Jets Shot Itself
[...] the F-35 was flying in a training mission at night [...] Arizona when it shot itself. This particular F-35 has an externally mounted gatling gun that fires a 25mm armor piercing high explosive round. [...] the gun discharged and the round exploded, damaging the underside of the jet.
[...] The F-35 is the most expensive weapon ever built. [...] The total cost for the entire F-35 program is estimated to be more than a $1 trillion over the course of the program's lifetime.'

'Gravitational lenses could allow a galaxy-wide internet
[...] our first emissaries to the stars will be robotic probes. [...] we will want them to phone home and tell us what they've discovered. The stars are distant, so the probes will need to make a very long-distance call.
[...] Although we can transmit powerful radio signals into space, the strength of these signals grows faint over stellar distances. Most of what we transmit couldn't be detected beyond a few light years given our current technology. Several solutions have been proposed, such as using focused laser light, but a new study looks at using gravitational lensing to get the job done.
[...] Since stars gravitationally warp the space around them, light passing near a star can be gravitationally lensed. This effect can be used to focus radio light similar to the way a glass lens focuses optical light.
[...] did some basic calculations of the kind of bandwidth one could get between the sun and nearby stars such as Alpha Centauri and Barnard's Star. The data rate could be on the order of kilobits/second, which is on the order of the old dial-up days of the internet. Not great by modern standards, but certainly enough to transmit useful images and data from another star.'

'The Massive Remnants of an Alien World Are Hidden Near the Earth's Core, Study Proposes
Two gigantic chunks of material lurking deep under the surface of Earth might be remnants of an alien world called Theia that violently collided with our infant planet in an ancient impact that created the Moon.
[...] suggests that two mysteriously dense zones located more than 1,000 miles under Earth's surface are "left-over Theia mantle materials," [...]
[...] geodynamical models as well as evidence collected about these subterranean zones, which are known as large low-shear-velocity provinces (LLSVPs), or more informally as the "blobs." Located under the Pacific Ocean and West Africa, these continent-sized LLSVPs are hundreds of miles high and thousands of miles across, making them the most massive formations in Earth's interior.
[...] Scientists have generally estimated that this bygone planet, named Theia after the mother of a Greek lunar goddess, was about the size of Mars, but some models suggest it was both smaller and bigger than that scale.
[...] initial calculation suggested the scale of the LLSVPs was roughly in line with an ancient impact origin, though Theia would need to have been bigger than Mars because a lot of this mantle material would be lost to space in the aftermath of the crash.
[...] if scientists could get their hands on pristine samples of the Moon's mantle, perhaps retrieved from the exposed crater in the lunar South Pole, they might be able to compare its composition to the makeup of the LLSVPs. Though these blobs are located far too deep inside our planet to be directly sampled, their composition can be inferred from seismic studies of their densities and analysis of volcanic islands that are linked to these deep zones via mantle plumes.'
