| A new dimension in magnetism and superconductivity launched Posted: 03 Nov 2021 12:08 PM PDT An international team of scientists has launched a new paradigm in magnetism and superconductivity, putting effects of curvature, topology, and 3D geometry into the spotlight of next-decade research. |
| Posted: 03 Nov 2021 12:08 PM PDT For the past seven years, an autonomous robotic rover, Benthic Rover II, has been continuously operational 225 kilometers off the coast of central California and 4,000 meters below the ocean's surface. This innovative mobile laboratory has further revealed the role of the deep sea in cycling carbon. The data collected by this rover are fundamental to understanding the impacts of climate change on the ocean. |
| Securing data transfers with relativity Posted: 03 Nov 2021 11:01 AM PDT The volume of data transferred is constantly increasing, but the absolute security of these exchanges cannot be guaranteed, as shown by cases of hacking frequently reported in the news. To counter hacking, a team has developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer. This system allows users to identify themselves in complete confidentiality without disclosing any personal information, promising applications in the field of cryptocurrencies and blockchain. |
| Posted: 03 Nov 2021 11:01 AM PDT A new analytical technique is able to provide hitherto unattainable insights into the extremely rapid dynamics of biomolecules. The team of developers is presenting its clever combination of quantum physics and molecular biology. The scientists used the technique to track the way in which the photoactive yellow protein (PYP) undergoes changes in its structure in less than a trillionth of a second after being excited by light. |
| Turning plastic grocery bags into sustainable fuel Posted: 03 Nov 2021 10:59 AM PDT Researchers report using catalytic pyrolysis to turn plastic wastes into a valuable fuel source. They focused on recycling plastic and upgrading plastic into other products or converting it to a vapor with heat, which met a catalyst and turned into the desired fuel-like product. This pyrolytic process transforms primary organic waste into a sustainable fuel or other valuable chemical. |
| Gravitational ‘kick’ may explain the strange shape at the center of Andromeda Posted: 03 Nov 2021 08:54 AM PDT A new study dives into the explosive physics of what happens when two supermassive black holes collide. |
| Quantifying spin for future spintronics Posted: 03 Nov 2021 08:54 AM PDT An international collaboration quantifies spin in a 2D quantum spin Hall insulator (QSHI), a promising option for future low-energy nano-electronic and spintronic devices. The team used anisotropic magnetoresistance (AMR) to reveal the relationship between the electrons' spin and momentum when the current is spin-polarized, demonstrating the promising potential of QSHI for novel spintronic devices, and proving the value of AMR for design and development of QSHI-based spintronic devices. |
| Electric soot collector shows promise in mitigating emissions from residential biomass combustion Posted: 03 Nov 2021 08:54 AM PDT A new study introduces a novel method to reduce particulate emissions from residential biomass combustion: the high-temperature electric soot collector, HiTESC. In HiTESC, an electrically insulated high-voltage electrode is installed in a combustion chamber, which generates an electric field. |
| Thin-film, high-frequency antenna array offers new flexibility for wireless communications Posted: 03 Nov 2021 07:50 AM PDT Researchers have taken a step toward developing a type of antenna array that could coat an airplane's wings, function as a skin patch transmitting signals to medical implants, or cover a room as wallpaper that communicates with internet of things (IoT) devices. |
| New software predicts the movements of large land animals Posted: 03 Nov 2021 07:50 AM PDT New software helps determine the movements of large wild animals thereby minimizing conflicts with people. The software is simpler than measurements obtained using radio transmitters and can be used where conventional methods fail. |
| Posted: 03 Nov 2021 07:50 AM PDT Government action is needed so driverless vehicles can be insured against malicious hacks which could have potentially catastrophic consequences, a study says. |
| ALMA scientists detect signs of water in a galaxy far, far away Posted: 03 Nov 2021 05:44 AM PDT Water has been detected in the most massive galaxy in the early Universe. Scientists studying SPT0311-58 found H20, along with carbon monoxide in the galaxy, which is located nearly 12.88 billion light years from Earth. Detection of these two molecules in abundance suggests that the molecular Universe was going strong shortly after the elements were forged in early stars. The new research comprises the most detailed study of molecular gas content of a galaxy in the early Universe to date and the most distant detection of H20 in a regular star-forming galaxy. |
| Tidal stream power can aid drive for net-zero and generate 11% of UK’s electricity demand Posted: 02 Nov 2021 06:01 PM PDT A day before world leaders meet at COP26 to discuss the importance of clean energy, scientists from across the UK say that harnessing the power of the ocean's tidal streams can provide a predictable and reliable means of helping to meet the country's future energy demand. |
| Artificial intelligence to detect colorectal cancer Posted: 02 Nov 2021 03:05 PM PDT A researcher found that artificial intelligence can accurately detect and diagnose colorectal cancer from tissue scans as well or better than pathologists, according to a new study. |
| Energy efficiency instead of long-term storage Posted: 02 Nov 2021 10:17 AM PDT Incorporating energy efficiency measures can reduce the amount of storage needed to power the nation's buildings entirely with renewable energy, according to a recent analysis. |
| Better models of atmospheric ‘detergent’ can help predict climate change Posted: 02 Nov 2021 09:54 AM PDT Earth's atmosphere has a unique ability to cleanse itself by way of invisible molecules in the air that act as minuscule cleanup crews. The most important molecule in that crew is the hydroxyl radical (OH), nicknamed the 'detergent of the atmosphere' because of its dominant role in removing pollutants. New research will aid in building more accurate computer models of OH. The study has important implications in advancing policies to combat climate change. |
| High-speed laser writing method could pack 500 terabytes of data into CD-sized glass disc Posted: 28 Oct 2021 09:04 AM PDT Researchers describe a new high-speed laser writing method for writing data that encompasses two optical dimensions plus three spatial dimensions. The new approach can write at speeds of 1,000,000 voxels per second, which is equivalent to recording about 230 kilobytes of data (more than 100 pages of text) per second. |
