Can either be a cell's dick used during bacterial conjugation, or little attachment anchors.

One of the very few encrypted emails... beauty. And they also have an encrypted password manager!!! Using this is a must as of 2023 basically. The only missing thing now is to find a fully open source alternative!!!

Sure, search capabilities have to be somewhat limited: proton.me/blog/engineering-message-content-search

techcrunch.com/2021/09/06/protonmail-logged-ip-address-of-french-activist-after-order-by-swiss-authorities/ you've fucking got to use Tor Browser with it if you want your IP to remain hidden, learn that...

Their backend is closed source: www.reddit.com/r/ProtonMail/comments/iyjqxf/is_protonmails_backend_open_source/

Are daily notifications without a recovery email possible? www.reddit.com/r/ProtonMail/comments/yjau8f/allow_daily_email_notifications_without_having_a/ OK, they do work actually.

The lack of Gmail dot trick is tragic however, and you have to pay for multiple aliases. But you can however create separate inboxes with the same cell phone verification however.

If you are a programmer, grep becomes a verb: "to grep" means "to search text files", much like "to Google" means "to search random stuff online".

PNG reference implementation. Ahh, if feels good to have a dominating open source reference implementation.

Also known as: Quantitative PCR (qPCR).

Like PCR, but the amplification machine measures the concentration of DNA at each step.

This describes one possible concentration detection method with fluorescent molecules that only become fluorescent when the DNA is double stranded (SYBR Green)

This allows you to predict the exact initial concentration by extrapolating the exponential curve backwards.

TODO: vs non-real-time PCR. Why can't you just divide by 2 for every heating step to reach back the original concentration? Likely the reaction reach saturation at an unknown step.

TODO: vs non-real-time PCR in medical diagnostics: do you really need to know concentration for diagnostics? Isn't it enough to know if the virus is present or not?

Isothermal means "at fixed temperature".

This is to contrast with the more well established polymerase chain reaction, which requires heating and cooling the sample several times.

The obvious advantage of isothermal methods is that their machinery can be simpler and cheaper, and the process can happen faster, since you don't have to do through heating and cooling cycles.
