Researchers may have developed long-lived biological computers that could potentially persist inside cells. Researchers forgo the traditional DNA-based approach, opting instead to use the nucleic acid RNA to build computers. The results demonstrate that the RNA circuits are as dependable and versatile as their DNA-based counterparts. What's more, living cells may be able to create these RNA circuits continuously, something that is not readily possible with DNA circuits.

Demand response, a measure taken to reduce the energy load in response to supply constraints, within the Texas electric grid has been a topic of recent conversation after the wake of Winter Storm Uri just one year ago. Demand response can enhance the reliability of the grid through renewable energy penetration and also significantly reduce price volatility, or fluctuation, in the wholesale electricity market.

Researchers have analyzed samples of NdBi crystals which display interesting magnetic properties. In their experiments including measurements at BESSY II they could find evidence for so called Fermi arcs in the antiferromagnetic state of the sample at low temperatures. This observation is not yet explained by existing theoretical ideas and opens up exciting possibilities to make use of these kind of materials for innovative information technologies based on the electron spin rather than the charge.

Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).

Two teams of physicists have designed the first programmable quantum sensor, and tested it in the laboratory. To do so they applied techniques from quantum information processing to a measurement problem. The innovative method promises quantum sensors whose precision reaches close to the limit set by the laws of nature.
