# Summary of IRC Log from #hplusroadmap (June 26, 2016)

* kanzure shared information about a Light Plate Apparatus (LPA), an open-hardware platform for optogenetics and photobiology that can deliver precise light signals to control gene expression, available for under $400 and assemblable by non-experts in one day.

* A significant advancement in genetic recording was discussed: "Continuous genetic recording with self-targeting CRISPR-Cas in human cells," which enables recording molecular stimuli as DNA mutations, potentially allowing tracking of signaling dynamics within cellular niches.

* The "Ex-STORM" technique was mentioned, which combines Expansion Microscopy with single molecule super-resolution microscopy, preserving fluorophores during sample preparation and enabling new approaches to visualizing expanded samples.

* Founders Fund published an article titled "Longevity Inc." about investments in longevity research, indicating growing interest in aging research from venture capital.

* A critique of blockchain applications was shared, questioning the claim that AI is necessary for smart contracts to replace human judgments in complex applications.

* SETI Institute videos were shared, including presentations on planetary cartography and the 100 Year Starship project, showing ongoing interest in space exploration and interstellar travel.

* A revised scientific estimate of the number of human and bacteria cells in the body was referenced via a biorxiv.org paper, representing updated understanding of human microbiome composition.
