- Rydberg atoms and Rydberg matter were highlighted as a potentially near-term, Earth-based technology with more immediate utility than speculative interstellar applications; a full graduate-level course on the topic from Leibniz University Hannover (2015) is openly available on Wikiversity.  
- A link to Winterberg’s 2009 arXiv paper “Ultradense Deuterium” (0912.5414) was shared as a resource for ultra-high-density fusion fuel concepts relevant to advanced propulsion and energy projects such as Orion’s Arm.  
- A participant with an implanted Medtronic PrimeAdvanced SureScan MRI neurostimulator (T8 model) described using the inductive recharging system for spinal-cord stimulation to manage chronic pain, illustrating a real-world cyborg use case.  
- The same participant demonstrated EEG-based mind-controlled robotics using Raspberry Pi and off-the-shelf electrodes, referencing Adafruit’s 2018 tutorial on recording brainwaves with a Pi as a starting point for DIY BCI work.  
- TensorFlow Lite for Microcontrollers was noted for running on an Arm Cortex-M3 in only 22 KB, enabling on-device keyword-spotting and other AI functions in ultra-low-power implants or wearables.  
- A pre-print study on COVID-19 (medRxiv 2020.05.14.20101998) was discussed, showing that each 1 dm² increase in visceral fat area raised ICU risk 22-fold and mechanical-ventilation risk 16-fold, while paradoxically finding lower BMI patients more likely to be intubated—possibly due to triage practices.  
- Debate followed on whether “overweight” BMI can be protective in the elderly; metformin was proposed as a confounder because diabetics on the drug reportedly outlive both untreated diabetics and non-diabetics, and it is the fourth most prescribed medication in the US.  
- Adipose-tissue composition was emphasized as critical: the inflammatory burden (leakiness, macrophage infiltration, cytokine release) correlates with the degree of polyunsaturated fatty acids in fat stores, potentially explaining heterogeneity in obesity-related risks.
