Nanofibrous hollow microspheres self-assembled from star-shaped polymers as injectable cell carriers for knee repair

For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue. Nature Materials – To repair complexly shaped tissue defects, an injectable cell carrier is desirable to …

Update of the Mundane Singularity: Tech Singularity Without Molecular Nanotechnology and Artificial General Intelligence Triggers

This weekend is when the Singularity Summit is being held in San Jose. Let us revisit the idea of technological singularity and the mundane singularity. Later this today there will be coverage of the Singularity Summit talks. Ray Kurzweil, defines the singularity as a period of extremely rapid technological progress. Robin Hanson, economist, proposes that …
