# Key Points from #hplusroadmap IRC Discussions

- Gene therapy and doping techniques were discussed, including siRNA doping, adenoviral methods, and naked DNA injection, alongside natural competence in cells for DNA uptake, with participants noting that even E. coli can develop the ability to take up external DNA at low rates.

- A participant shared their experience building what they described as "probably the safest DIY tDCS (transcranial direct current stimulation) device," indicating ongoing interest in DIY neurostimulation technology within the community.

- The "Inventory for Composable Elements (ICE)" was mentioned as an open-source registry for biological parts tracking being developed by the Joint Bio Energy Institute, representing efforts to standardize synthetic biology components.

- 3D printing discussions compared Makerbot and RepRap capabilities, noting that while Makerbot offers two-material printing, it lacks dissolvable support materials, while RepRap has more advanced material options including PCB and tissue printing capabilities.

- Participants discussed the need for developing 3D printing materials that are dissolvable without harsh chemicals and have appropriate melting points, highlighting ongoing challenges in additive manufacturing.

- HP's memristor technology was shared via a Kurzweil AI article, with claims it would "reinvent computer memory by 2014," demonstrating the community's interest in next-generation computing hardware technologies.

- A collaborative mind mapping tool called "beautifulmind.io" was shared, prompting discussion about different brainstorming and information organization tools for collaborative thinking.
