# Summary of #hplusroadmap IRC Discussion

• A research paper on "Holographic acoustic elements for manipulation of levitated objects" from Nature Communications was shared, demonstrating advanced techniques for acoustic manipulation of objects.

• Plant mutation techniques were discussed, with participants sharing research papers about electron beam radiation equipment for biotechnological materials and the unintended consequences of plant transformation.

• A participant reported testing "Joylent" (a Soylent alternative) as a meal replacement option, suggesting it might be preferable to standard cafeteria food.

• An article on nanoscale metal 3D printing was shared, describing a technique using AFM/STM cantilever tips as electrodes for electrochemical deposition to achieve nanoscale precision in fabrication.

• Technical details about a mini laser etcher project were discussed, including PWM (pulse-width modulation) control implementation and the potential use of RC filters to convert PWM signals to analog voltage for better laser current stabilization.

• A critique of contemporary science fiction was briefly mentioned, with one participant expressing disappointment about the current state of science fiction as featured in an Adobe Slate publication.
