MIT Researchers Make New Chips That Work On Light (3 minute read)

Lightelligence is a startup from MIT that makes high-speed optical chips with low power consumption and low latency. Its processors have orders of magnitude better performance than standard architectures. The chips generate very little heat due to their low power consumption. Servers for computationally intensive AI processing take up a huge chunk of data center capacity, so there is a lucrative market for chips that reduce running costs while increasing computational capability.
This self-healing concrete automatically fills in cracks (2 minute read)

A new type of concrete uses an enzyme found in red blood cells to heal itself. Making concrete more durable could help lower carbon emissions due to concrete production, repair, and transport. Earlier attempts at making self-healing concrete used bacteria, but the process was slow and expensive. Carbonic anhydrase is the enzyme that transfers CO2 from cells into the bloodstream. When added to concrete powder, it helps the concrete turn CO2 from the atmosphere into calcium carbonate crystals, filling in cracks. It can be put into a spray and used to fix cracks in traditional concrete.

This Weirdly Smart, Creeping Slime Is Redefining Our Understanding of Intelligence (7 minute read)

Physarum polycephalum is a yellow slime mold that can learn, solve complex puzzles, and remember novel substances. It doesn't have a central nervous system or any specialized tissues. Scientists have always assumed that thought required a brain or some type of higher information processing system, but the mold proves otherwise. While the mold is acellular, it still has parts that operate independently, sharing information with its neighboring sections. The article contains pictures and videos of the mold.
