Mar 18, 2022 (Nanowerk News) Tohoku University scientists in Japan have developed a virus-based approach for measuring variations in gene regulatory elements, called transcription factors, as conditions change in live organisms. The research, published in the journal iScience ("PCR-based profiling of transcription factor activity in vivo by a virus-based reporter...
Magnet-free chiral nanowires for spintronic devices
Mar 18, 2022 (Nanowerk News) Researchers from the Basque Nanoscience Research Center CIC nanoGUNE (San Sebastian, Spain), in collaboration with POLYMAT (San Sebastian, Spain), the Institute of Physics of the Martin Luther University Halle-Wittenberg and the Max Planck Institute of Microstructure Physics (both in Halle, Germany) demonstrate the all-electrical generation,...
With machine learning to new supramolecular materials
Mar 17, 2022 (Nanowerk News) A team of scientists at the TUM Innovation Network ARTEMIS (Artificial Intelligence Powered Multifunctional Material Design), named after the Greek goddess of hunting, are researching supramolecular materials. They are investigating their use in medicine and energy production supported by machine learning. “The idea of ARTEMIS...
Web3 technology puts farmers in charge of their data
Mar 17, 2022 (Nanowerk News) Innovations such as Web3, the third generation of the internet, and easy-to-use video-based technologies in local languages have the potential to drive change in agriculture in developing countries, say technology advocates. Web3, which refers to efforts to create a decentralised version of the internet based...
Arsenic makes black phosphorus hop for energy efficiency
Mar 17, 2022 (Nanowerk News) The quest for thermoelectric materials that efficiently convert changes in temperature into electric voltage is challenging. For optimal performance, a material must conduct small amounts of heat and large amounts of electricity. However, crystal structure and electrons that carry electricity also carry heat. Researchers have...
Engineering an ‘invisible cloak’ for bacteria to deliver drugs to tumors
Mar 17, 2022 (Nanowerk News) Columbia Engineering researchers report that they have developed a “cloaking” system that temporarily hides therapeutic bacteria from immune systems, enabling them to more effectively deliver drugs to tumors and kill cancer cells in mice. By manipulating the microbes’ DNA, they programmed gene circuits that control...
Physicists find direct evidence of strong electron correlation in a 2D material for the first time
Mar 17, 2022 (Nanowerk News) In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that allows electrons to flow with zero resistance. These materials, which...
Paving the way to tailor-made carbon nanomaterials
Mar 17, 2022 (Nanowerk News) Carbon exhibits a remarkable tendency to form nanomaterials with unusual physical and chemical properties, arising from its ability to engage in different bonding states. Many of these “next-generation” nanomaterials, which include nanodiamonds, nanographite, amorphous nanocarbon and nano-onions, are currently being studied for possible applications spanning...
Mathematical paradoxes demonstrate the limits of AI
Mar 17, 2022 (Nanowerk News) Humans are usually pretty good at recognising when they get things wrong, but artificial intelligence systems are not. According to a new study, AI generally suffers from inherent limitations due to a century-old mathematical paradox. Like some people, AI systems often have a degree of...
Moon’s orbit proposed as a gravitational wave detector
Mar 17, 2022 (Nanowerk News) Researchers from the UAB, IFAE and University College London propose using the variations in distance between the Earth and the Moon, which can be measured with a precision of less than a centimeter, as a new gravitational wave detector within a frequency range that current...
