# Key Points from #hplusroadmap IRC Discussion

• Participants explored the feasibility of implantable biofuel cells in humans, discussing optimal placement locations, glucose availability, and clotting risks, with consensus that retroperitoneal surgery would be too invasive for DIY experimentation.

• The conversation covered existing implantable chemical release systems like Norplant, Implanon, and Mirena, while speculating about the development of more advanced controlled-release implant technologies.

• A research paper on giant squid eyes was shared, explaining their evolutionary advantage: the 27cm eyes with 9cm pupils evolved specifically to detect large predators like sperm whales at distances over 120m in deep ocean environments.

• French researchers' breakthrough in cellular rejuvenation was discussed, where scientists restored youth to 100-year-old cells using six genetic factors (OCT4, Sox2, Myc, KLF4, NANOG and LIN28) typically used for inducing pluripotency.

• Participants debated whether organizations like the Richard Dawkins Foundation should redirect efforts toward life extension research, suggesting that achieving longevity escape velocity could naturally reduce religious belief by eliminating the psychological need to cope with mortality.

• Technical tools for DIY projects were compared, including magnetic linear encoders with 15-micron resolution and digital calipers with 0.001 resolution that would be less affected by magnetic field interference.

• The relationship between atmospheric oxygen content and insect size was discussed, referencing research on tracheal development in Drosophila melanogaster and mentioning a project breeding silkworms in high-oxygen environments.
