- Expansion microscopy (ExM) was discussed as a low-cost, open-source imaging technique that uses baby-diaper hydrogel polymers and DNA oligo linkers to physically enlarge biological samples up to 4–10×, enabling super-resolution imaging on ordinary microscopes (Cho et al., Nature Methods 2016).  
- nmz787_ shared the PRESTO-Tango paper (Nature Structural & Molecular Biology 2015) describing an open-source, genome-wide platform for interrogating the entire human GPCRome with barcoded reporters, aimed at accelerating drug discovery.  
- Practical DIY lab infrastructure: a scanning electron microscope requiring ~10–15 A at 100 V AC was being wired into a home lab; Oregon homeowners can legally perform their own electrical work under state code with permits and inspections.  
- Machine-learning resources linked: TensorFlow beginner MNIST tutorial and Michael Nielsen’s deep-learning chapter on the softmax activation function were posted for newcomers to neural networks.  
- Antigen retrieval and chemical fixation artifacts in immunohistochemistry were noted, with Wikipedia references provided for mitigating formaldehyde-induced protein masking.
