    [–] 'Bubble boy disease' cured using HIV with gene therapy at St. Jude's 10ebbor10 9 points ago in news

    A lot of genetic engineering is done with viruses or bacteria that transfer genetic material. It's easier to hijack a system's that's already evolved to insert genetic code than it is to create your own.

    [–] The real reason Boeing’s new 737 Max crashed twice 10ebbor10 1 points ago in CatastrophicFailure

    Is it because once the MCAS systems were disabled, the pilots pulled back on the stick in vain without being able to change the trim?

    The first crash never disabled MCAS.

    As you can see, pilot and MCAS keep trying to struggle for control of the trim till the end.

    The second crash did disable MCAS, but failed to recover.

    So the question becomes why are our pilots able to do it but they couldn't for the two flights that crashed.

    The Ethiopean airlines flight shut down MCAS. The problem is that shutting down MCAS also shuts down the pilot's electric trim controls.

    That means that the pilot has to retrim his plane using a manual wheel. However, if there's a lot of force on the horizontal stabilizer (because the pilot is trying to pull up) then it can be impossible to move the horizontal stabilizer manually. There's a trick to bypass this problem (basically, it involves rocking the plane by repeatedly letting the nose dip down), but it was removed from the manuals somewhere in the 70's.

    But nobody mentions anymore the experience levels of the Ethiopian pilots. The co-pilot had something like 200-300 hours flight time, where it takes almost 3000 hours to be a professional pilot in the states.

    The captain had 8500 hours though.

    If I tell people that the car I'm selling doesn't need any fuel to drive, they'll be very happy to hear it. I'll still be sued when it turns out that's a lie.

    It's Boeing's responsibility to tell their clients that they can not make the plane that the clients want, if they can't do so.

    This wasn't some Machiavellian scheme. It was a conscious design/engineering decision that was heavily tested and mostly has worked out fine over tens (hundreds) of thousands of flights.

    It's was a badly designed system.

    They had an automated system which is capable of commanding severe and continuous nose-down inputs with little documentation. This system relies on a single sensor, with no cross-checking (despite a second sensor being available) or redundancy. If that sensor fails, then the system will naively believe it, potentially resulting in continuous nose down inputs.

    In default configuration, the pilot is not informed that such a discrepancy between sensors exist. Both a warning light or a sensor value display are optional extras for which airlines need to pay.

    The only way to stop the system is to shut down the electric trim controls, but doing so also shuts down the pilot trim controls, forcing the pilot to undo MCAS's mistake using a tiny wheel. However, if there's a lot of force on the elevator (because the plane is diving and the pilot is trying to pull up), then the pilot(or co-pilot) is not physically able to efficiently turn this wheel.

    Honestly, it's lucky they didn't lose more planes.

    [–] CMV: people who suggest voter idea is racist are the real racist. What 10ebbor10 1 points ago in changemyview

    Do these people think minorities can’t get IDs. Do they think they are inferior to whites and are incapable of getting id.

    People who oppose voter ID know that in reality, research is done to find exactly which ID's that the targeted demographic doesn't tend to own.

    For example, in Texas, a handgun license counts as ID, but a federal/state id or student card does not. By carefully crafting which ID's are accepted and which are not, you can target your demographic.

    https://edition.cnn.com/2017/04/11/politics/texas-voter-id-law-discriminate/index.html

    Here's another example. It's required that the ID has a street address, but native Americans who live on reservations don't have an address, because the reservation doesn't have street names.

    https://www.npr.org/2018/10/13/657125819/many-native-ids-wont-be-accepted-at-north-dakota-polling-places

    This is combined with other changes to voting polling law, which can also be targeted. Here the Republicans asked which ways of voting where most used by black voters, and then eliminated those.

    They also implemented voter ID, and carefully selected which ID's they allowed.

    The law’s voter identification provision, for instance, “retained only those types of photo ID disproportionately held by whites and excluded those disproportionately held by African-Americans.”

    https://www.nytimes.com/2017/05/15/us/politics/voter-id-laws-supreme-court-north-carolina.html

    None of those tricks can be uniquely used against minorities. You can use them against any demographic. But in practice, there's only 1 party in the US who likes using them, and only certain demographics that they target.

    [–] Adults of Reddit born prior to 1980, do you remember the Chernobyl Disaster? What were you doing and what was your reaction upon learning what happened? 10ebbor10 5 points ago * (lasted edited a day ago) in AskReddit

    I have access to the book, and I can thus say that it's not in there.

    At around 1:30 p.m., the pilot took the helicopter up to a hundred meters, flew north, over the first of three villages close to Pripyat, and then turned to the west. The cockpit dosimeter remained at zero. Volodin dropped to fifty meters and continued toward the next village; nothing.

    He brought the helicopter down farther, to just twenty-five meters, but the needle of the radiometer didn’t move. Volodin suspected that it just wasn’t sensitive enough to get a reading. Passing the final turning point on the survey flight plan, Volodin began following the railway line, in the direction of the Chernobyl plant itself. On his right, he could see the village of Chistogalovka, where more people were tilling their gardens. The wind was now blowing southwest, carrying a thin trail of white smoke—or steam, perhaps—from the direction of the plant and the railway station, toward the village. Chistogalovka wasn’t a part of the survey flight plan, but Volodin decided to take some readings anyway.

    What if the smoke was radioactive? This stuff could be falling right on people’s heads. As he passed the railway station, he pulled the control yoke over. The helicopter banked right. Large beads of liquid began to form on the canopy. At first, Volodin thought it was rain. But then he noticed that it wasn’t breaking over the glass like water: instead, it was strange, heavy, and viscous.

    It flowed slowly like jelly and then evaporated, leaving a salty-looking residue. And the sky remained clear. He bent over the control panel, and looked up: directly above him, the same whitish smoke was blowing overhead, thin in some places, dense in others. Almost like a cloud. “Captain, it’s maxed out!” the flight engineer shouted. “What’s maxed out?” “The DP-3. The needle’s stuck.” “Then switch to a higher range,” Volodin said, and turned to check the dial himself.

    But the radiometer was already calibrated to its most extreme setting. The needle was glued to the far end of the range, at 500 roentgen per hour. And Volodin knew that the device took its readings from a receiver in the back of his seat. It seemed impossible: the level of radiation inside the cockpit had risen beyond the worst expected in a nuclear war.

    Whatever it was, he had to get them away from the cloud immediately. Volodin threw the yoke forward. The nose of the helicopter dipped down and to the left. The treetops flashed beneath them, a smear of green. He pushed the machine to its maximum speed, away from the railway station and toward Pripyat. Then the cockpit door flew open, framing the terrified civil defense major, his own radiometer in his hand. “What have you done?” the officer screamed against the howl of the engines. “You’ve killed us all!”

    I looked it up.

    The dosimeter the book mentions on the soviet Helicopters is a DP-3. It looks like this Link.

    As you can see, it's not circular, it just goes from left to right.

    In addition, the pilot, Sergei Volodin, was interviewed as late as 2006.

    The book is not the problem, you are.

    That seems like a made-up story.

    Only 1 helicopter crew died, and they died because the helicopter collided with a cable from a crane and crashed.
    Many helicopters flew over the core to dump stuff onto it (didn't really work), and none of those died from radiation sickness.
    I can't find any evidence of dosimeters with circular dials existing.

    Edit: Checked the book. The story is real, but you're seriously misrepresenting it.
    1) There was no circular meter. Both book and interview just indicate that they maxed out the instrument when they flew into the radiation plume.
    2) Neither book nor reality claim they approached the core. They just flew through the gas plume to measure the radiation.
    3) None of them got a lethal dose. They all lived. ((Though, to be fair to the book, it doesn't claim they died)).

    [–] French forces say they'll use everything but Trump's suggestion to fight the Notre Dame fire 10ebbor10 1 points ago in worldnews

    The full context makes it worse.

    WSJ: You think North Korea is trying to drive a wedge between the two countries, between you and President Moon?

    Mr. Trump: I’ll let you know in—within the next 12 months, OK, Mike?

    WSJ: Sure.

    Mr. Trump: I will let you know. But if I were them I would try. But the difference is I’m president; other people aren’t. And I know more about wedges than any human being that’s ever lived, but I’ll let you know. But I’ll tell you, you know, when you talk about driving a wedge, we also have a thing called trade. And South Korea—brilliantly makes—we have a trade deficit with South Korea of $31 billion a year. That’s a pretty strong bargaining chip to me.

    With that being said, President Xi has been extremely generous with what he’s said, I like him a lot. I have a great relationship with him, as you know I have a great relationship with Prime Minister Abe of Japan and I probably have a very good relationship with Kim Jong Un of North Korea.

    I have relationships with people, I think you people are surprised.

    [–] A leader of Germany's far-right AfD party on Tuesday tried to link the devastating fire at Paris's Notre-Dame cathedral to rising "intolerance" against Christians in Europe, although French investigators believe the inferno was an accident 10ebbor10 7 points ago * (lasted edited a day ago) in worldnews

    France had over 800 churches vandalized last year alone.

    I can't find any credible sources for that figure. Do you have one?

    Even the non-credible sources seem to suggest that the 800 figure also includes stuff like theft, so it seems like the figure may overinflated.

    So anti vaxxers are decreasing in number, not increasing as hysterists would have you believe.

    Uhm

    0.3 -> 1.3% is an increase, not a decrease.

    10% think the risk of vaccines outweight the benefit.

    So, it's not that big, but unfortunately we need a vaccination rate of around 95% for herd immunity to be fully effective.

    https://www.pewresearch.org/science/2017/02/02/vast-majority-of-americans-say-benefits-of-childhood-vaccines-outweigh-risks/

    In addition, among parents of young children (which is the demographic that matters), 17% thinks the risk of side effects is high, and 26% thinks the risk is medium. That is considerably higher than for other demographics.

    Secondly, whilst the cathedral as a whole is very historic and has stood for centuries, the roof is newer: I read it was replaced in the 19th Century.

    This is incorrect.

    The Spire was replaced in the 19th century. The roof was partially repaired at that time, but was still mostly original wood. Most of that wood (from the 12-13th century) has burned.

    [–] American tourists in town detected (Cadiz, Spain) 10ebbor10 8 points ago in pics

    The use of the capirote or coroza was prescribed in Spain and Portugal by the holy office of Inquisition. Men and women who were arrested had to wear a paper capirote in public as sign of public humiliation. The capirote was worn during the session of an Auto-da-fé. The colour was different, conforming to the judgement of the office. People who were condemned to be executed wore a red coroza. Other punishments used different colours.
