Phys.org January 4, 2023 Recent decades have witnessed exponential growth in the volume of new scientific and technological knowledge, thereby creating conditions that should be ripe for major advances. Yet studies suggest that progress is slowing in several major fields. A team of researchers in the US (University of Minnesota, University of Arizona) analysed the claims of new scientific and technological knowledge at scale across six decades, using data on 45 million papers and 3.9 million patents from six large-scale datasets, together with a new quantitative metric that characterizes how papers and patents change networks of citations in science and technology. They […]

Scientists discover material that can be made like a plastic but conducts like metal
Science Daily October 26, 2022 An international team of researchers (USA – University of Chicago, Stony Brook University, Argonne National Laboratory, South Korea) discovered a way to create a material that can be made like a plastic but conducts electricity more like a metal when they strung nickel atoms like pearls into a string of molecular beads made of carbon and sulfur. The material easily and strongly conducted electricity when heated or chilled or exposed to air and humidity, or even dripped acid and base. But the most striking thing was that the molecular structure of the material was disordered. […]
All-in-one device uses microwave power for defense, medicine
EurekAlert April 8, 2021 Researchers at Purdue University used composite based nonlinear transmission lines (NLTLs) as complete high-power microwave systems, encompassing high-voltage pulse and high-power microwave formation. The device combines the elements of traditional NLTLs into a composite-based system and eliminates typical bulky auxiliary equipment. The system is charged using a DC high-voltage supply and discharged using a high-voltage, gas-based switch. It eliminates the need for external pulse generation and is more rugged due to the solid-state construction. NLTLs have proven effective for applications in the defense and biomedical fields. They create directed high-power microwaves that can be used to […]
Translation software enables efficient DNA data storage
Nanowerk April 2, 2021 In support of the IARPA Molecular Information Storage (MIST) program researchers at the Los Alamos National Laboratory have developed a software called the Adaptive DNA Storage Codec (ADS Codex), that translates data files from what a computer understands into what biology understands. The short-term goal of MIST is to write 1 terabyte—a trillion bytes—and read 10 terabytes within 24 hours for $1,000. ADS Codex addresses two big obstacles to creating DNA data files: Figured out new strategies for error correction as the error rates while writing to molecular storage; Added additional information called error detection codes […]
Discovery of a ‘holy grail’ with the invention of universal computer memory
EurekAlert June 20, 2019 An international team of researchers (UK, Spain) has developed an oxide-free, floating-gate memory cell based on II-V semiconductor heterostructures with a junctionless channel and non-destructive read of the stored data. While writing data to DRAM is fast and low energy, the data is volatile and must be continuously ‘refreshed’ to avoid it being lost. This is clearly inconvenient and inefficient. Flash stores data robustly, but writing and erasing is slow, energy intensive and deteriorates data, making it unsuitable for working memory. The new device combines the advantages of both without their drawbacks…read more. Open Access TECHNICAL […]
5 Times People Thought a Science Idea Was Crackpot, And Were Proven Spectacularly Wrong
Science Alert February 12, 2019 Robert H. Goddard said “every vision is a joke until the first man accomplishes it; once realised, it becomes commonplace.” Science has the power to change the world, but it’s not always an easy path to enlightenment. At many junctures throughout history, proponents of revolutionary ideas have come up against criticism and pushback from the establishment. Science is all about experimentation, trial, error, and evidence. It may have taken years, but each of the following five ideas, once considered preposterous or silly, has now been accepted as correct: Continental drift ; Evolution ; Heliocentricity ; […]

DARPA has an ambitious $1.5 billion plan to reinvent electronics
MIT Technology Review July 30, 2018 To move beyond Moore’s Law the chances are that radically new materials, and new ways of integrating computing power and memory, will be needed. Shifting data between memory components that store it and processors that act on it sucks up energy and creates one of the biggest hurdles to boosting processing power. DARPA launched a $1.5 billion, five-year program known as the Electronics Resurgence Initiative (ERI) to support work on advances in chip technology. The agency has just unveiled the first set of research teams selected to explore unproven but potentially powerful approaches that […]
