Ok, maybe it’s possible that they aren’t using a very focused electron beam, but usually when scientists think about using an electron beam they mean something inside of a machine like an SEM or e-beam lithograph. These only operate on small areas.
If an unfocused beam (and therefore lower energy density) can be used, then this could likely be scaled more easily. Even if a focused beam is needed, scaling may still be possible, but will likely require additional developments to create that process.
Obviously it’s over hipped news, but, would it be ethical to print neutral network brains made of human cells? How about the question… How many chicken brain cells does it take to do the same job as a given amount of human cells? And if that number is 3 or 46, does that mean that we are 3 or 46 times smarter on average than a chicken? Or maybe 1 human vote is 45 times a chicken’s? 1/45th vote rule?
A similar experiment was actually done 20 years ago, using rat neurons to pilot a flight simulator. 25,000 rat neurons in a petri dish were capable of flying the simulated F-22. research.ufl.edu/publications/…/extract2.html
Will the missile know that Osama has be gone for a while? Is it going to get bored just hanging from an F14 all day? Will it go off if it’s depressed? Is it male or female? Will you feel bad if it’s a really sexy female missile? How do you grow up a missile control neutral network? Do you have to have the birds and bees talk with your missile? If Johny the missile jumps off the empire State building, does your missile have to hump from the empire State building? Gosh! So many questions!
Do female missiles have a period? Can two missiles that really love each other have baby missiles? Do they go off when they go off? Where does daddy missile work? Does he cheat with mommy missile?
But seriously, the Thought Emporium is a great channel. If you wish to feel amazed and inspired, grab a drink, dial down the lights and binge a few videos in a row.
Article title seems AI generated. Makes it sound like the whole of Alaska Airlines was barred.
Due to this, Alaska Airlines opted to limit the aircraft from extended flights over water to ensure that the plane “could return very quickly to an airport” if the warning light reappeared, according to Jennifer Homendy, National Transportation Safety Board (NTSB) chair.
Looks like Alaska knew about the previous warnings and voluntarily pulled it from international flights.
This sounds like one of those sciency bullshit articles where
a) the study was on a subcategory of proteins that in some very boring and specific cases influence the aging of a certain type of cell in a minor way
b) the study was a miniscule pilot study with 10 participants
c) it explicitly said that it's results are more than shaky and need further testing to prove anything
d) it didn't mention humans aging at all
e) the participants were some kind of worm
but some journalist read half the excerpt, misunderstood it completely and did a catchy article about what he hallucinated into the study.
I’m extremely curious what those weapon systems look like. A missile? Maybe two? 10 bricks? 5,000 ball bearings? Any object hitting anything at ~4,000 mph would do a fuckton of damage.
This new plane is a hypersonic weapon delivery drone, barely related to the SR-71 aside from the speed it can travel.
As to the sixty years thing, satellites made spyplanes nearly entirely obsolete and traditional aircraft with stealth technology covered the remaining cases well enough that there wasn’t a need for more speed. Research went into making missiles better instead, and this is designed to be a launch platform for those missiles.
Then why do we still operate the U2? SR-71 was operated all the way until 1999. Hubble was launched in 1990 so the large mirrors for spy telescopes had to have been in use well before that.
