- Two new pre-prints describe “programmable RNA writing” via engineered trans-splicing: one demonstrates rewriting endogenous human transcripts (bioRxiv 2024.01.29.577779) and the other general programmable RNA writing (bioRxiv 2024.01.31.578223); both were highlighted as technically neat but questioned for therapeutic permanence.  
- A second, related technique—programmable RNA bridge recombination—was also circulated (tweeted by Patrick Hsu), underscoring a burst of innovation in RNA-level genome editing tools.  
- Discussion of the “Lulu and Nana Foundation” resurfaced with a recent tweet from He Jiankui, suggesting ongoing activity or a namesake organization.  
- Consumer biotech products were reviewed: an enzymatic, rinse-free kitchen cleaner (Naturally Clean) and veterinary-grade nano-hydroxyapatite enzymatic toothpaste for pets—both noted as examples of off-the-shelf bio-catalytic chemistry.  
- The peptide BPC-157 (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) was extensively examined: rodent data show oral, topical, and subcutaneous efficacy for tendon/ligament healing, IBS relief, anti-inflammatory effects, and dopaminergic modulation; no exact BLAST match exists, hinting at artificial or highly modified origin.  
- BPC-157 is orally bioavailable—rare among peptides—and is banned by WADA as a performance-enhancing recovery agent, prompting debate over whether anti-doping rules obstruct legitimate medical care.  
- Phage therapy for STI prevention was shared (LiveScience article), framed as an emerging alternative to antibiotics, though noted that the quoted experts are not U.S.-based.  
- A brief aside referenced Greg Egan’s “Teranesia” (anarcho-biopunk use of veterinary drugs on humans) and linked to a web-comic about paperclip maximizers, tying pop-culture references to bioethical themes.
