"De novo" means "starting from scratch", that is: you type the desired sequence into a computer, and the synthesize it.
The "de novo" part is important, because it distinguishes this from the already well solved problem of duplicating DNA from an existing DNA template, which is what all our cells do daily, and which can already be done very efficiently in vitro with polymerase chain reaction.
Notably, the dream of most of those companies is to have a machine that sits on a lab bench, which synthesises whatever you want.
The initial main applications are likely going to be:but the real pipe dream is building and bootstraping entire artificial chromosomes
- polymerase chain reaction primers (determine which region will be amplified
- creating a custom sequence to be inserted in a plasmid, i.e. artificial gene synthesis

Nuclera eDNA enzymatic de novo DNA synthesis explanatory animation (2021)
Source. The video shows nicely how Nuclera's enzymatic DNA synthesis works:- they provide blocked nucleotides of a single type
- add them with the enzyme. They use a werid DNA polymerase called terminal deoxynucleotidyl transferase that adds a base at a time to a single stranded DNA strand rather than copying from a template
- wash everything
- do deblocking reaction
- and then repeat until done
In some systems, e.g. including Metamath, modus ponens alone tends to be enough, everything else can be defined based on it.
CIA 2010 covert communication websites 2013 DNS Census virtual host cleanup heuristic keyword searches Updated 2025-04-24 +Created 1970-01-01
There are two keywords that are killers: "news" and "world" and their translations or closely related words. Everything else is hard. So a good start is:
grep -e news -e noticias -e nouvelles -e world -e global
iran + football:
- iranfootballsource.com: the third hit for this area after the two given by Reuters! Epic.
3 easy hits with "noticias" (news in Portuguese or Spanish"), uncovering two brand new ip ranges:
- 66.45.179.205 noticiasporjanua.com
- 66.237.236.247 comunidaddenoticias.com
- 204.176.38.143 noticiassofisticadas.com
Let's see some French "nouvelles/actualites" for those tumultuous Maghrebis:
- 216.97.231.56 nouvelles-d-aujourdhuis.com
news + global:

"headline": only 140 matches in 2013-dns-census-a-novirt.csv and 3 hits out of 269 hits. Full inspection without CDX led to no new hits.
He looks like an older and more experienced dude compared to Bezos at the time.

Amazon.com Continues to Grow by NBC 15 (2014)
Source. Features short excerpt of filmed interview with Shel.visualizing the Riemann hypothesis and analytic continuation by 3Blue1Brown (2016) is a good quick visual non-mathematical introduction is to it.
The key question is: how can this continuation be unique since we are defining the function outside of its original domain?
The answer is: due to the identity theorem.
CIA 2010 covert communication websites Are there .org hits? Updated 2025-04-24 +Created 1970-01-01
Previously it was unclear if there were any .org hits, until we found the first one with clear comms: web.archive.org/web/20110624203548/http://awfaoi.org/hand.jar
Later on, two more clear ones were found with expired domain trackers:further settling their existence. Later on newimages.org also came to light.
Others that had been previously found in IP ranges but without clear comms:
.org is very rare, and has been excluded from some of our search heuristics. That was a shame, but likely not much was missed.
Ways in which it can happen:
There are unlisted articles, also show them or only show them.
