1. Auditing LLM Chemical Priors for Multi-Objective Bayesian Optimization of Chemical Reactions: A Validity, Alignment, and Diversity Benchmark1
An unreviewed benchmark finds that language-model suggestions can help, leave unchanged or harm multi-objective reaction optimization, depending on the reaction dataset. Diversity-based initialization matches or exceeds the reported benefits. The results make a useful case for testing prior alignment before spending experimental resources. Our account is restricted to the repository-deposited abstract.1
2. Continuous Solar-Adaptive Electrochemical Stripping for Circular Nitrogen Recovery from Urine2
An unreviewed study couples sunlight-responsive flow control to multistage electrochemical stripping of urine. More than 80 hours of off-grid operation reportedly recovered over 75% of incoming nitrogen as ammonium sulfate despite changing sunlight. The work connects process control with nutrient recovery; its battery-saving comparison is modeled. Our account is restricted to the deposited abstract.2
3. Reimagining the Wolff-Kishner Reduction: Light-Driven Carbonyl Deoxygenation without Strong Base3
Researchers report a light-driven Wolff–Kishner reduction that removes oxygen from aryl and aliphatic carbonyl compounds near ambient temperature under essentially neutral conditions. This expands access to a classical transformation while addressing reactions associated with strong base and heat. Mechanistic studies suggest substrate-dependent activation pathways. Our account is restricted to the publisher-deposited abstract.3
4. Direct Tunnel Channeling of Unstable Amino Aldehyde Intermediates Enables Stepwise Diamination in Transaminases4
Engineering a tunnel between transaminase subunits helps shuttle unstable amino aldehydes between catalytic sites before they escape into solution. A Shimia marina enzyme variant reportedly improves catalytic efficiency 1.98-fold for converting diformylfuran into a diamine. Stopped-flow kinetics and simulations support altered intermediate transport, informing sequential biocatalysis. Our account is restricted to the publisher-deposited abstract.4
5. Accelerated discovery of thermostable mRNA–lipid nanoparticle vaccines using data-efficient AI5
AGENT combines high-throughput experiments with Bayesian optimization to identify thermostable mRNA–lipid nanoparticle formulations in six iterations over one month. The reported solid formulations retained bioactivity after more than two months at 37°C; vaccine responses were tested in rodents and nonhuman primates. This supports a formulation-search strategy, without establishing human performance. Our account is restricted to the publisher abstract.5
