# Summary of IRC Log from #hplusroadmap (July 7, 2012)

* Discussion about transcranial direct current stimulation (tDCS), with particular interest in high-definition tDCS (HD-tDCS), noting it shows promise and is more accessible than transcranial magnetic stimulation (tMS), though effectiveness needs improvement.

* Conversation about the Microwave Auditory Effect and whether it could be implemented using 2.4GHz signals, with links to a WiFi-based radar project, concluding it would require access to digital signal processing source code.

* Research shared on bi-maternal mice (mice derived from two mothers) showing they are smaller and live 30% longer than normal mice, with links to studies about the Rasgrf1 gene's role in this longevity effect and its connection to the GH/IGF1 pathway.

* Brief discussion about genetic determinism and the overuse of "Brave New World" references in discussions about genetics and biotechnology, noting the phrase originated with Shakespeare.

* Exchange about surface-mount soldering techniques, with participants confirming that regular SMD components can be soldered by hand with practice, while BGA (Ball Grid Array) is more challenging and LGA (Land Grid Array) requires specialized reflow soldering methods.
