RNA and DNA Engineered to Count While in Living Cells

Researchers are focusing on designing small biological circuit components to accomplish specific tasks. Journal Science abstract. Supplemental material. To demonstrate their concept, the team built circuits that count up to three cellular events, but in theory, the counters could go much higher. The first counter, dubbed the RTC (Riboregulated Transcriptional Cascade) Counter, consists of a …

Superconducting Computer Chip Breakthrough

Artist view of the implantation of gallium ions (animated in blue) into germanium wafers followed by a reconstruction of the lattice using short-term flash-lamp annealing and, finally, of the observation of superconductivity at low temperatures. Other than in normal conductors, superconductivity is caused by the formation of electron pairs with anti-parallel momentum and spin (animated …
