• Tasso Hemolink, a needle-free microfluidic vacuum device, was presented as a way to collect capillary blood without lancets or syringes.  
• JangoBio’s parabiosis-based rejuvenation program claims that restoring youthful circulating reproductive hormones can reverse aging, although no detailed mechanism has been published.  
• A comprehensive literature review on non-viral gene delivery to the brain was circulated, covering PAMAM dendrimers, transferrin- and RVG-peptide–targeted nanoparticles, and microbubble/ultrasound “sonoporation” to transiently open the blood–brain barrier.  
• The newly released “Multilayer Connectome of Caenorhabditis elegans” paper was discussed; it integrates monoaminergic and neuropeptide signaling networks with the classic synaptic connectome, and the OpenWorm project is working to incorporate these extrasynaptic edges into PyOpenWorm.  
• Recent experimental papers on optimizing PAMAM–gold nanoparticle conjugates and on increasing lipoplex concentration at the cell surface to boost transfection in hard-to-transfect cells were shared.  
• A DIYbio thread on using Terminal deoxynucleotidyl Transferase (TdT) for enzymatic DNA synthesis received a detailed reply summarizing protocols, suppliers, and troubleshooting tips.
