Oscillations are widespread throughout the natural world and a number of fascinating inorganic oscillating reactions are known—but the formation and control of oscillating, self-replicating synthetic systems has remained challenging. Now, it has been shown that chemically fuelled oscillations within a network of organic replicators can drive supramolecular assembly and disassembly.

If you are interested in artificial general intelligence (AGI), then I have a panel discussion to recommend. My friend, David Wood, has done a masterful job of selecting three panelists with deep insight into possible regulation of AGI. One of the panelists was my friend, Dan Faggella, who was eloquent and informative as usual. For this session of the London Futurists, David Wood selected two other panelists with significantly different opinions on how to properly restrain AGI.


An artificial general intelligence (AGI), by one definition, is an agent that requires less information than any other to make an accurate prediction. It is arguable that the general reinforcement learning agent AIXI not only met this definition, but was the only mathematical formalism to do so. Though a significant result, AIXI was incomputable and its performance subjective. This paper proposes an alternative formalism of AGI which overcomes both problems. Formal proof of its performance is given, along with a simple implementation and experimental results that support these claims.

Here are some things I would expect any AGI to be able to do:…


Epistemic status: trying to feel out the shape of a concept and give it an appropriate name. Trying to make explicit some things that I think exist implicitly in many people’s minds. This post makes truth claims, but its main goal is to not to convince you that they are true.

Today we’re going to shine some light on Lumen, the fully dynamic global illumination and reflections system featured in Unreal Engine 5.

Hi, we’re Daniel and Krzysztof, engineers working on Lumen is Unreal Engine 5’s fully dynamic global illumination and reflections system, which is enabled out of the box. It is designed for next-generation consoles and high-end visualizations beyond games like architectural visualization. Here, we’ll walk through Lumen’s features and give an overview of the technical details. For a complete reference, see the Lumen documentation.
