Thread 508903296

Anyone worked with an electron microscope? I work in lab medicine and have never ever seen those things in a lab.

I just see a kike rubbing his hand.

1pbtid kike slide threads created once every minute and jannies allow it. Sage

This virus was the first virus ever to be invented

The Hubble space telescope launched 30 years ago. It seems that space telescopes are just as large and expensive then as they are now -- has there been no improvement?

>>508904350
Well, you are opening another can of worms here

I see it too bros.

>>508903832
Just make more money. Anything is possible when you aren't a lazy bum.

>>508903296 (OP)
Give more info.
>t. work in a uni biotech lab

>>508903296 (OP)
yes

electron microscopy has its own lab

>>508905373
Why electron microscopes aren’t used for diagnosis of viruses?

>>508905690
rRNA sequences are used to identify viruses

The news that spark this post was a Greek farmer dying today from Crimea Congo virus. Thought crimea was too far from Congo. It seems the Congo specimens were processed in Rockefeller virus institute in New York in 1956. What method did exist back then to verify that the virus samples from Crimea and Congo was the same virus? I don’t think they could tell that at the time

>>508904350
Things aren't becoming cheaper to produce just by being older, they get cheaper by an having over-production or a suddenly dropping demand creating oversupply.
Somehow I doubt there are warehouses full of space telescopes waiting for sales, so it won't get cheaper.
I am pretty sure it could be done somewhat smaller today. But they won't build those things for shit and giggles, unless they have some contracts researching prototypes that survived DOGE.
Things like that are only made specifically to customer-order and build in whatever size/weight said customer has demanded/is able to fit into their rocket payloads.
Besides, the successor James-Webb went operational 2022.

no they couldn't

That's spaghetti

>>508906240
The hospital I work literally paid over 200k investment for covid pcr infrastructure and trained totally ignorant on pcr technologists in a month. They didn’t have a problem to do that

>>508903296 (OP)
You don’t work in a lab.

>>508906370
Maybe they lied about it then?

I do. Try me

>RNA-dependent RNA polymerase RNA sequences (aka RdRp)
viruses may also be classified by certain proteins
they can also be classified by DNA sequences

>>508907136
Yeah I don’t think in 1956 they had assays for proteins

>>508906494
>pcr
You could train monkeys to do this. No comparison to electron microscope.

>>508907291
What’s so special about electron microscope that makes its use prohibitive except mythological laboratories?

>>508906370
there was no way to verify then
idk what this is about
to answer your original question, elctron microscopes are typicallyt in the basement and a lab all their own, and have cryo EM too, etc

>>508907439
I'm not saying that it requires some kind of esoteric knowledge or whatever, just that it is not as comparable to pcr as you are suggesting.

>>508907212
>assays for proteins
Just got curious, if a Biuret test qualifies that one has been used since 1857.

>electron microscope
Nope never been so lucky. But you can do some cool shit like destroying cancer cells by viewing at it's resonating frequency

>>508907439
needs a vacuum chamber
needs high voltage
may need a few tanks of gas (pure nitrogen, helium) depending on what you are doing with it
a few consumable parts like the emitter, expensive to replace when it wears out
very sensitive to vibration so may need an isolated quiet room

that said, I've known folks who put up a shingle operating surplus electron microscopes

>>508907776
This is for peptide bonds. All proteins test positive. But in 1956 you couldn’t tell two samples contained the same protein

>>508903296 (OP)
Uh oh, electronbros, I don't feel so good...

>>508907991
Ah okay.

>>508906494
Also no Covid 19 virus pics through electron microscope ever after all this worldwide fuss.

>>508903463
stfu brainlet

This shit i more interesting the 95% or more of all the other dogshit you thirdie retards, niggers, kikes and bots all shit out endlessly.

>>508907439
just to let you know, random mutations can also cause reversion mutants, so a more pathogenic viral strain can lose its pathogenicity and then regain it later after multiples rounds of replication
and just b/c a lab contained a sample of a virus doesn't mean that virus isn't in the wild, too, it just means the lab has a sample of it

>>508908382
Oh found these
https://www.microscopeworld.com/p-4317-covid-19-under-the-microscope.aspx
They’re from fort Detrick, that was the Center of US biological weapons program till 1969 and now is multinational bioresearch facility

>>508908774
Forgot pic

>>508903296 (OP)
There was a really cool webm. Just kept zooming in and zooming in.

>>508908737
An interesting stuff the pharma representative (that handled the pcr equipment all over many Greek hospitals) told us was that never, in the whole world, was a covid 19 infection in a laboratory setting.

here is an EM image of SARS2 (aka CoVID)

>>508908827
Found it

>>508909080
Source NIAID-RML the same origin with the link I posted above

>>508903463
This. I can't believe a BBC spam thread died for this..

>>508909000
>was a covid 19 infection in a laboratory setting.
oh yes there were many SARS2 strains isolated and sequenced
pic rel is the sequence that was first isolated
china never gave up patient zero's samples or sequence, so picrel was considered one of the earliest cases

>>508909497
That’s interesting too. I just meant no person ever worldwide was infected with Covid 19 while handling specimens in the laboratory. That’s very strange

>>508909080
impressive how they are able to distinguish blue electrons from brown electrons

>>508909080
coronaviruses were thought to be the common cold, they have been around forever in innocuous strains
coronmaviridae often coinfect cells with other +ssRNA enveloped respiratory viruses like the flu

SARS and MERS were also beta coronaviruses, but went quickly extinct, as most viral strains do due to random mutations

>>508909300
noice

>>508909732
they are colored afterward for teaching purposes or to discern between cell structures in papers

>>508909080
someone better be making a merchant

>>508909864
maybe they could try adding big red arrows and celebrities with gaping mouths as well

>>508909300
Really cool webm that.
Anyone else always gets this disorientated feel when looking closely at any micro electronics?
It is like if you are flying miles above some cityscape and dive down toward ground level at speed.
