They also play an important ecological role in global biogeochemical cycles. Recent research by researchers at the University of Kaiserslautern-Landau (RPTU) has identified a previously unknown auxiliary metabolic gene in aquatic phages, thereby significantly expanding the previous understanding of these bacterial predators. /news/2024-10-bacteria-auxiliary-metabolic-genes-phages.html Cell & Microbiology Molecular & Computational biology Tue, 15 Oct 2024 16:49:04 EDT news648229741 Researchers at QuTech have found a way to make Majorana particles in a two-dimensional plane.

When studying systems comprised of several strongly interacting particles (i.e., many body systems) in two or more dimensions, numerically predicting the amount of information shared between these particles, a measure known as entanglement entropy (EE), becomes highly challenging. /news/2024-03-method-rnyi-entanglement-entropy-auxiliary.html Quantum Â鶹ÒùÔºics Thu, 28 Mar 2024 06:50:01 EDT news630753225 Peaceful though it may seem from Earth, space is beset by "weather" that can prove perilous for the sensitive—and expensive—technology aboard the spacecraft and satellites increasingly populating the realms outside our atmosphere. /news/2024-03-tech-local-space-weather-real.html Planetary Sciences Wed, 20 Mar 2024 13:30:55 EDT news630160252 Particle accelerators hold great potential for semiconductor applications, medical imaging and therapy, and research in materials, energy and medicine.

This property is chirality, a feature of the matter that plays with the symmetry of biological structures at different scales, from the DNA molecule to the tissues of the heart muscle. /news/2022-04-reveals-mechanism-chirality-molecules-nanoscale.html Bio & Medicine Nanomaterials Tue, 26 Apr 2022 15:28:06 EDT news570205679 Microfluidic devices are compact testing tools made up of tiny channels carved on a chip, which allow biomedical researchers to test the properties of liquids, particles and cells at a microscale. They are crucial to drug development, diagnostic testing and medical research in areas such as cancer, diabetes and now COVID-19. However, the production of these devices is very labor-intensive, with minute channels and wells that often need to be manually etched or molded into a transparent resin chip for testing. While 3D printing has offered many advantages for biomedical device manufacturing, its techniques were previously not sensitive enough to build layers with the minute detail required for microfluidic devices. Until now. /news/2022-04-3d-technique-game-changer-medical.html Materials Science Tue, 12 Apr 2022 15:58:24 EDT news568997893 Glasses are an indispensable part of everyday life. One of the most important reasons for this is that glass objects can be manufactured almost universally and inexpensively in a wide variety of shapes and sizes using their corresponding melts. Processing in the (viscous) liquid phase offers a versatility that can hardly be achieved with other materials. However, this presupposes that the material from which the glass is made in terms of its chemical composition can be melted at all. /news/2021-09-glasses-unmeltable-compounds.html Materials Science Wed, 29 Sep 2021 11:55:49 EDT news552135346 Heaters, sold under such well-known brand names as Webasto and Eberspächer, among others, are used in both passenger cars and heavy-duty vehicles to preheat the engine and provide additional cabin heating while driving. Emissions from heaters are not regulated, although they are widely used in especially colder regions, such as Finland. Therefore, they can have a significant impact on local air quality, and even on regional or global emissions budgets. /news/2021-09-surprisingly-high-emissions-fuel-powered-auxiliary.html Environment Thu, 09 Sep 2021 10:47:46 EDT news550403264 In a study published in Â鶹ÒùÔºical Review Letters, a team led by academician Guo Guangcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has made progress in high dimensional quantum teleportation.

This has been especially true with respect to the paradigms for explaining material properties using the concept of topology, "ideas that are currently revolutionizing condensed matter physics," according to Tel Aviv University researcher Roni Ilan. While topological physics first emerged in condensed matter physics, the ideas have now spread into many other areas, including optics and photonics, as well as acoustics and other mechanical systems, where things have been getting a little tricky. /news/2020-11-topological-mechanical-metamaterials-newton-law.html General Â鶹ÒùÔºics Quantum Â鶹ÒùÔºics Thu, 19 Nov 2020 09:39:16 EST news525001142 An official report admitting to toxic emissions being generated by three waste-to-energy (WtE) plants operating in the Indian capital has thrown a question mark on the future of WtE incinerators as a way to deal with the municipal solid waste generated by the country's 1.3 billion people. /news/2020-10-waste-to-energy-delhi-pollution-woes.html Environment Thu, 22 Oct 2020 09:40:02 EDT news522576733 An infinite chain of hydrogen atoms is just about the simplest bulk material imaginable—a never-ending single-file line of protons surrounded by electrons. Yet a new computational study combining four cutting-edge methods finds that the modest material boasts fantastic and surprising quantum properties. /news/2020-09-infinite-chains-hydrogen-atoms-properties.html General Â鶹ÒùÔºics Mon, 14 Sep 2020 12:40:02 EDT news519305711 Â鶹ÒùÔºicists have long sought to understand the irreversibility of the surrounding world and have credited its emergence to the time-symmetric, fundamental laws of physics. According to quantum mechanics, the final irreversibility of conceptual time reversal requires extremely intricate and implausible scenarios that are unlikely to spontaneously occur in nature. Â鶹ÒùÔºicists had previously shown that while time-reversibility is exponentially improbable in a natural environment—it is possible to design an algorithm to artificially reverse a time arrow to a known or given state within an IBM quantum computer. However, this version of the reversed arrow-of-time only embraced a known quantum state and is therefore compared to the quantum version of pressing rewind on a video to "reverse the flow of time." /news/2020-08-time-reversal-unknown-quantum-state.html Quantum Â鶹ÒùÔºics Mon, 10 Aug 2020 09:40:01 EDT news516269275 Simulating computationally complex many-body problems on a quantum simulator has great potential to deliver insights into physical, chemical and biological systems. Â鶹ÒùÔºicists had previously implemented Hamiltonian dynamics but the problem of initiating quantum simulators to a suitable quantum state remains unsolved. In a new report on Science Advances, Meghana Raghunandan and a research team at the institute for theoretical physics, QUEST institute and the Institute for quantum optics in Germany demonstrated a new approach. While the initialization protocol developed in the work was largely independent of the physical realization of the simulation device, the team provided an example of implementing a trapped ion quantum simulator. /news/2020-03-quantum-simulators-sympathetic-cooling.html Quantum Â鶹ÒùÔºics Fri, 13 Mar 2020 09:32:59 EDT news503310774 Researchers of the University of Basel have developed a new method with which individual isolated molecules can be studied precisely—without destroying the molecule or even influencing its quantum state. This highly sensitive technique for probing molecules is widely applicable and paves the way for a range of new applications in the fields of quantum science, spectroscopy and chemistry, as the journal Science reports. /news/2020-03-perturbation-free-molecules.html Quantum Â鶹ÒùÔºics Thu, 12 Mar 2020 14:00:02 EDT news503225972
