Aging Analytics Agency has launched an interactive IT-platform alongside its “Longevity Industry in California Landscape Overview 2019” report that turns the report’s static mindmaps into dynamic and interactive infographics, enabling complex interactions between industry entities and stakeholders to be visualized, filtered, searched and thus more easily understood.

We exhibit a simple, systematic procedure for detecting and correcting errors using any of the recently reported quantum error-correcting codes. The procedure is shown explicitly for a code in which one qubit is mapped into five. The quantum networks obtained are fault tolerant, that is, they can function successfully even if errors occur during the error correction. Our construction is derived using a recently introduced group-theoretic framework for unifying all known quantum codes.
Gating—controlling the state of one qubit conditioned on the state of another—is a key procedure in all quantum information processors. As the scale of quantum processors increases, the qubits will need to interact over larger and larger distances, which presents an experimental challenge in solid-state architectures. Wan et al. implemented the 20-year-old theoretical proposal of quantum gate teleportation that allows separated qubits to interact effectively. They deterministically teleported a controlled-NOT gate between two computational qubits in spatially separated zones in a segmented ion trap, demonstrating a feasible route toward scalable quantum information processors.

Large-scale quantum computers will require quantum gate operations between widely separated qubits. A method for implementing such operations, known as quantum gate teleportation (QGT), requires only local operations, classical communication, and shared entanglement. We demonstrate QGT in a scalable architecture by deterministically teleporting a controlled-NOT (CNOT) gate between two qubits in spatially separated locations in an ion trap. The entanglement fidelity of our teleported CNOT is in the interval (0.845, 0.872) at the 95% confidence level. The implementation combines ion shuttling with individually addressed single-qubit rotations and detections, same- and mixed-species two-qubit gates, and real-time conditional operations, thereby demonstrating essential tools for scaling trapped-ion quantum computers combined in a single device.

ETH researchers have found an error-free way to store information in the form of DNA, potentially preserving it for millions of years: encapsulate the information-bearing segments of DNA in silica (glass), using an error-correcting information-encoding scheme.
Scrolls thousands of years old provide us with a glimpse into long-forgotten cultures and the knowledge of our ancestors. In this digital era, in contrast, a large part of our knowledge is located on servers and hard drives, which may not survive 50 years, let alone thousands of years. So researchers are searching for new ways to store large volumes of data over the long term.
Recently, 300,000 year old mitochondrial DNA from bears and humans has been sequenced. DNA has also been utilized as a coding language, for applications in forensics, product tagging, and DNA computing, the researchers note.
Elon Musk says adding two to four Raptor Engines to the Starship will let it go sub-orbital for 6000 miles at mach 20. This would mean trips like San Francisco to Shanghai or New York to Berlin. Many world cities are within 6000 miles of each other.
Boeing extended range 767s can reach 6000 miles and the newer 777 and 787 have longer ranges.
If SpaceX can determines ways to save 30% on Starship point to point efficiency then they could get to 8000-mile ranges. This might be possible by lightening landing gear and heat shields. They could need less heat shields for sub-orbital only vehicles.
Some antidepressants could potentially be used to treat a wide range of diseases caused by bacteria living within cells, according to work by researchers in the Virginia Commonwealth University School of Medicine and collaborators at other institutions.
Research published in the April print edition of the journal Life Science Alliance, shows that antidepressant drugs called FIASMAs, including desipramine, amitriptyline, and nortriptyline, halt the growth or kill four different intracellular bacterial pathogens in tissue cell culture and animal models.
“Antibiotic options for diseases caused by intracellular bacteria are limited because many of these drugs cannot penetrate our cell membranes. In essence, the bacteria are protected,” said Jason Carlyon, Ph.D., leader of the study and professor in the VCU Department of Microbiology and Immunology.
