    I'll share an anecdote as well. I'm not sure how much others know about the history of flight before the Wright Brothers but a friend was doing research and learned about an earlier inventor, Gustave Whitehead. He flew (and crashed) several years before the Wrights, his craft even flew further and higher than the Wright flyer before hitting a building (which still stands, and I've probably looked at it a hundred times before I heard about it's significance). There's testimony that this guy was up in the air from eye witnesses including the chief of police!

    My friend posted all of the evidence that he'd found including newspaper archives and police reports from the ensuing crash, and within a couple of days, he received a call from the FBI enquiring about what exactly he was doing with the information he found. If they are actively policing something that went on over a century ago, I can very much imagine there's a tight leash on any current conspiracies out there and it's being monitored exactly what is shared.
    There are also newspaper stories from the 1890s about "air ships" appearing in the area and hovering, then zooming off. One - and I swear it's true that the article appeared, that a newspaper had the story, not the subject, necessarily - had someone "strange looking" get off it and say he's from the North Pole.

    There's another place in Texas that had a newspaper article - and no one questions that the article was real and ran in the late 1890s - that one of the "air ships" crashed into a farmer's windmill, the little town found a "victim" and had a small service to bury him. One guy was quoted as saying "One things for sure, the poor little feller was not of this world" - and everyone went back to work as if that wasn't some huge deal, just a sad thing he died, "not of this world" wasn't earthshaking.

    As for the video of the "unknown" object, I seriously doubt it's from outer space or some other "world." I agree with you that it's likely U.S. military, 70 miles off the coast of San Diego is a place with a lot of military exercises. It does sound like something so advanced that pilots had no idea what it was. The fact that there's a warehouse in Las Vegas with UFO objects of unknown alloys is an interesting tid-bit.

    The military industrial community has stuff that - direct quote - that "would make George Lucas drool" is one quote from the head of Lockheeds "Skunk Works" top secret program. Lots of just weird stuff. Who knows? Not us. Some people say that even if the tech is just human, they'd keep it out of people's hands bc the economy is so based upon, and reliant upon hydrocarbon industry that to introduce a new energy source, from wherever one wants to posit, that it would be far too disruptive to release it all at once. I can see that.

    Mars ice will help astronauts: https://www.sciencenews.org/article/...ronauts?tgt=nr

    Martian ice has a thin skin. The newly discovered exposure of ice on steep banks suggests that the Red Planet’s ice sheets are buried by just a meter or two of soil, researchers report in Science January 12.

    “What’s new and exciting here is that these ice sheets start quite shallowly,” says planetary scientist Colin Dundas of the U.S. Geological Survey in Flagstaff, Ariz. That could be good news for future astronauts hoping to use that water to drink, or to create oxygen to breathe or make fuel for returning spacecraft (SN: 1/20/18, p. 22)

    Someone will find a way. If you're skied Afghanistan, and some have, they'll find a way.

    No way could I not post an article named: https://www.space.com/39361-monster-...uble-burp.html


    Monster Black Hole Unleashes Messy Double 'Burp

    Black holes are voracious eaters, but it also turns out they don't have very good table manners," Julie Comerford, an astronomer at the University of Colorado Boulder, said during a news conference at the event today. "We know a lot of examples of black holes with single burps emanating out, but we discovered a galaxy with a supermassive black hole that has not one but two burps." [The Strangest Black Holes in the Universe]
    "This new burp is actually moving like a shock wave — it's coming out very fast, and so it's kind of like a sonic boom of a burp," Comerford said, "whereas the gas to the south shows us an older burp that happens 100,000 years earlier before that newer burp."

    “I don’t expect us to be perfect anytime soon,” guard Silas Melson said, “but one thing I do expect is trying to get better every day and playing tougher, harder and more physical than the opponent.”

    Thx, Reno. Many people have posted good things in here, my fav thread.

    Close enough to science and an excellent article as public service. http://www.esquire.com/news-politics...ear-bomb-plan/

    Minutes to Live: When the Nuclear Push Alert Is Not a Mistake
    For this reason, officials say, the instinct to flee is a dangerous one to heed. “Previously what we’ve chosen to practice is evacuation—the fire alarm goes off, get out. It’s understandable—there’s a hazard, take action,” says Buddemeier. But a panicked, uninformed attempt to escape could prove even more deadly than the initial blast, as civilians risk unnecessary exposure to radiation and rescuers fail to grasp potentially lifesaving measures like the fact that they can safely move into the damage zone as long as they stay upwind of the fallout cloud. “That’s a big mental shift we’re trying to get people through. Just like a tornado, getting into the center of the building or down into the basement is much better than trying to outrun the fallout.”



    The key is to get inside as quickly as possible. If you can shelter within ten to fifteen minutes, you can avoid the most damaging radiation. “What is a good shelter? Concrete, underground, center of the building if you have time,” Hawaii’s Miyagi says. “Get as low [in a building] as possible.” If you’re caught outside and survive the blast? Get inside and get naked. Simply removing your clothes eliminates 90 percent of radioactivity.


    Moving millions or even thousands of people on such short notice would be logistically impossible, and would risk stranding them in situations far more dangerous than the ones they were fleeing. Similar reasoning guided the city of Houston’s refusal to evacuate residents in advance of Hurricane Harvey—plus, today’s cars are built with too much plastic to offer much protection against radiation
    Kind of a cool article. Basic gist is that a disaster is a disaster, and what you have planned for your Earthquake, Tsunami, Hurricane disaster will work almost just as well for terrorism or nuclear warhead.

    Huge news on cause of plague: http://www.bbc.com/news/science-environment-42690577#

    Black Death 'spread by humans not rats'

    But a team from the universities of Oslo and Ferrara now says the first, the Black Death, can be "largely ascribed to human fleas and body lice".


    So we could construct models of the disease dynamics [there]."

    He and his colleagues then simulated disease outbreaks in each of these cities, creating three models where the disease was spread by:

    rats
    airborne transmission
    fleas and lice that live on humans and their clothes

    In seven out of the nine cities studied, the "human parasite model" was a much better match for the pattern of the outbreak.

    It mirrored how quickly it spread and how many people it affected.

    "The conclusion was very clear," said Prof Stenseth. "The lice model fits best."

    "It would be unlikely to spread as fast as it did if it was transmitted by rats.

    "It would have to go through this extra loop of the rats, rather than being spread from person to person."

    Very interesting.
    My friend that does the historical research posted some of the statistics for our county of the Spanish influenza outbreak and just how quickly it spread and the sheer numbers that were infected and dying within days of the initial victim were just astonishing. Sure medicine has come a long way in 100 years but I can't even imagine what it was like during the many plagues that hit with even more rudimentary medical knowledge.
    Apparently there's a theory out there that certain blood types had natural immunity to many of the sicknesses that have wiped out big swaths of the population.

    It would be terrifying either way, but to have no idea as to the disease process and bacterial infection would make the world seem utterly random, and have people suffering tremendously while also wondering if they "did something" to deserve it. Very sad to picture, 3/4 of towns wiped out and all.

    Dedicated to Martin Centre Mad Man, for the nice shout-out on MBB

    Some good news for a very serious problem, this whole article worth the time: https://www.sciencenews.org/article/...itively-solved

    The mystery of vanishing honeybees is still not definitively solved

    Colony collapse disorder, or CCD, as the sudden mass honeybee losses were called, has faded in recent years as mysteriously as it began. It’s possible the disappearances could start up again, but meanwhile bees are facing other problems.

    CCD probably peaked around 2007 and faded since, says Jeff Pettis, who during the heights of national curiosity was running the Beltsville, Md., honeybee lab for the U.S. Department of Agriculture’s research wing. And five years have passed since Dennis vanEngelsdorp, who studies bee health at the University of Maryland in College Park, has seen a “credible case” of colony collapse.



    “I think I know what happened,” says Pettis, now in Salisbury, Md., consulting on pollinator health. His proposed scenario for CCD, like those of some other veterans of the furor, is complex and doesn’t rest on a single exotic killer. But so far, no experiment has nailed the proof.
