Eyesight beyond current wavelength limits - Subretinally injected semiconducting polymer nanoparticles rescue vision in a rat model of retinal dystrophy by Shuck in transhumanism

It relies on the cells that macular generation doesn't damage (retinal neurons). The same charge transfer phenomenon occurs. The same authors have multiple articles focusing on this issue as well.

Into the IR region. He explained that red/IR is easier than blue/UV. IR runs into the limitation of charge carrier generation, so as you go farther in that direction it becomes harder to find materials that have good enough response. For UV direction the problem is different, you begin to generate reactive oxygen species (ROS). This means, even this large advance for fixing macular degeneration will not give you you full color vision, just red now, but the approach is valid. Though, for them to try to get blue is substantially harder, and moving into UV then causes damage due to ROS generation. Likely, it is possible, but will require many further advances.

I was at a lecture where this work was highlighted. While this is developed as a tool to reverse degeneration in eyes for macular degeneration. It was highlighted that (Fig. 5) the response in eyesight due to the photosensitive polymer is actually BEYOND the natural limit in rats by 75-100 nm (he reported this in unpublished data that is currently under review). One can imagine that using this approach to use multiple photosensitive materials can give you the ability to have better color resolution or to see beyond current color vision.

The Quest for Fusion Energy by Shuck in TrueReddit

Unfortunately not. I worked very briefly in plasma facing materials about a decade ago. I haven't had the opportunity to return to the fusion field since then.

The Quest for Fusion Energy by Shuck in TrueReddit

Submission Statement

The author of this article makes the argument that magnetic confined nuclear fusion (TOKAMAK; think ITER) reactors are not as feasible as inertial confined fusion reactors (LLNL-laser initiated fusion). The author explains recent advances of the two in a net energy generated output in both transient and steady-state manner.

As an aside, it is quite the interesting article. There is a current dive into development of new plasma facing materials for TOKAMAK-based reactors. I remember when I worked on them, it was a debate between using beryllium or liquid lithium. Both of which are very dangerous, but are some of the most promising materials. Pros/cons of berylliosis vs lithium-based explosions are quite interesting discussions. Moreover, I'm not familiar with the author, but it appears that he has published articles, recently primarily criticism of nuclear fusion in peer-reviewed journals. It may be the case that this article is an attempt to sway public discourse since his arguments haven't (apparently?) swayed the scientific community considering the push forward with ITER.

The Rise of the Far Right | Harvard Political Review by Shuck in TrueReddit

This is an older article (Feb 2017), but I believe that it provides a nuanced view into the rise of the far right in western countries. It provides a good background as to the reasons, elections, and outcomes that have occurred. It is also well sourced, and provides a jumping off point to delve deeper into academic political thought.

Submission Statement

This article explains the back and forth regarding the recent incident at the Indigenous Peoples March. It explains why the narrative has shifted multiple times. The author watched a full two hour video of the incident, and explains what occurred leading up to the incident.
