# Summary of ##hplusroadmap IRC Log (September 17, 2015)

* Ken Hayworth (Brain Preservation Foundation) published a response to MIT Technology Review, addressing criticisms of brain preservation techniques.

* A new optogenetics breakthrough was discussed involving OptoSTIM1, a hybrid protein combining cryptochrome 2 with STIM1 that allows for greater control of calcium channels in cells, potentially enabling neurological enhancements.

* Interstellar travel concepts were explored, including a system of mirrors and Fresnel lenses to both accelerate and decelerate lightsails, with discussion of how this approach could overcome rocket equation limitations.

* Researchers shared advances in molecular sensing technology, with discussion of variable laser spectrometers that use optical heterodyning as potentially revolutionary for portable spectroscopy.

* A D-Link security vulnerability was highlighted, showing serious security flaws in consumer networking equipment.

* Discussion of laboratory work included tissue clearing techniques for microscopy of brain tissue and potential projects involving oligonucleotide ligase investigation and follistatin-Fc expression in yeast.
