doi: 10.2210/rcsb_pdb/goodsell-gallery-048 The Virus that Cures It’s been over 25 years since the science magazine Discover first ran an extraordinary article about how a long-forgotten medical treatment, used in the former Soviet country of Georgia, could save us from the growing threat of untreatable, drug-resistant infections.
Most people would take the two CRISPR gene-editing components (a Cas9 protein and guide RNA), package them up inside of a virus, and then inject the viruses into the skulls of mice. 📎 Papers Strands of DNA can be used to build molecular logic gates. If you want to edit a gene inside of a neuron, what do you do? From Stahl E.C.

DNA sequences are designed on a computer, and it takes a dozen or more clicks to change a single nucleotide. DNA sequences are also checked by hand, so it’s easy to make a mistake. The tool outputs a DNA sequence that encodes all the required enzymes. A phage is a virus that infects bacteria.

“The recombinant DNA breakthrough has provided us with a new and powerful approach to the questions that have intrigued and plagued man for centuries. The central dogma is often depicted as DNA→RNA→protein, but it’s much more: A biophysical marvel inside the smallest of vessels. Biology is a Burrito.
By combining mammoth DNA recovered from ancient permafrost with stem cells of the species’ closest living ancestor, the Asian elephant, the company aims to make hybrid embryos. These embryos must then be nurtured and able to grow to term, ideally inside of an Asian elephant. .” Presumably, Lamm aims to fill in these gaps.
Some scientists even think it had a virus defense system; “researchers say LUCA likely housed 19 CRISPR genes, which bacteria use to slice up viral threats,” reports Quanta Magazine. DNA and RNA molecules are also built from exclusively right-handed nucleic acids.
This led some to believe that the Black Death was caused by a different pathogen, perhaps anthrax or a virus like influenza or even Ebola. pestis DNA in the dental pulp of skeletons in various medieval burial sites across Europe, which corresponded to recorded outbreaks, including in cemeteries used exclusively for Black Death victims.
Short DNA strands were discovered that can specifically and tightly bind to zinc and cadmium ions. Perhaps there is now a way to use DNA to extract metals: You could fuse the DNA strands to an antibody, coat them onto electronics, and then use a column to isolate the DNA:metal compounds? coli DNA using a Retro-Cascorder.
This week: A way to measure a transgene’s expression in the brain using ultrasound, a DNA sequencing method that uses 1000x less reagents, and base editors get even smaller. An engineered version of this protein can convert DNA bases with efficiencies up to 92%. so this Digest will be published more irregularly.

Influenza incidence and severity are increasing , against a backdrop of novel drifts (small genetic changes) and shifts (larger changes) to the virus, all against a backdrop of novel infection pathways, such as birds to cows to people. The mRNA in COVID vaccines tells cells to produce the virus’s spike protein.
