# Key Points from IRC Log (June 11, 2011)

• Ultrasound brain stimulation technology was discussed extensively, with kanzure sharing William Tyler's patent filing that describes "low-intensity (<500 mW/cm²), low-frequency ultrasound (<0.9 MHz)" methods for modulating neuronal activity, which Tyler calls a "brain regulation interface."

• A Quantified Self (QS) meetup in Paris was reported as disappointing by Utopiah, who noted it was primarily a showcase for startups rather than knowledge sharing, contrasting with Bay Area QS meetups which prohibit sales presentations.

• kanzure shared several resources related to aging research, including papers on NF-κB signaling in aging processes and a collection of reorganized papers in biology and neuroscience directories (http://diyhpl.us/~bryan/papers2/).

• Several interesting scientific resources were shared, including StemBook.org for stem cell research and a video about Argyroneta aquatica (diving bell spider) along with related scientific literature.

• The SKDB project was discussed, which aims to create a package management system for physical objects similar to apt-get, allowing users to download designs and bills of materials for DIY scientific equipment like OpenPCR and DremelFuge.

• Ed Boyden's optogenetics work was mentioned in relation to a TED talk, with kanzure noting this technology had been presented earlier than the May 2011 date claimed.

• DARPA's "Novel Neural Interface Workshop" was referenced along with fiber optic neural interfaces, indicating ongoing military research interest in brain-computer interface technologies.
