# Key Points from #hplusroadmap IRC Discussion (August 28, 2012)

• Researchers discussed ultrasound as a potentially more precise alternative to transcranial direct current stimulation (tDCS) for brain stimulation, sharing a collection of research papers on the topic.

• A technical discussion compared computer vision techniques for polygon recognition, including FAST corner detection, Hough transforms, and edge detection methods, with particular focus on mobile device performance constraints.

• Participants debated the intersection of leftist politics and transhumanism in response to Dale Carrico's anti-transhumanist writings, exploring how peer-to-peer production models might address resource distribution challenges in futurist scenarios.

• A biohacker shared information about "magnetofection," a technique where DNA attached to iron particles is forced into cells using oscillating magnetic fields to increase successful DNA transfer rates.

• Several DIY biology resources were discussed, including a kit for adding DNA to cat cells, GFP (Green Fluorescent Protein) plasmids, and documentation on working with bioluminescent dinoflagellates.

• The channel noted significant technical resources including the International Workshop on Bio-Design Automation (IWBDA) wiki and Boston University's CIDAR (Cross-disciplinary Integration of Design Automation Research) wiki for synthetic biology work.
