Phys.org / New NMR method allows the observation of chalcogen bonds
Toward the right side of the periodic table below oxygen, are the chalcogens, or "ore-forming" elements. The chalcogens that occur naturally, including sulfur, selenium and tellurium, are all somehow involved in biological ...
Phys.org / Magnetic microbots steer quantum sensors inside living cells
Cells are squishy and soft. Tiny nanometer-sized particles such as quantum sensors cannot move freely inside them due to viscous drag, which makes sensing challenging. Researchers at the Indian Institute of Science (IISc) ...
Phys.org / A tiny protein tweak, finally traceable: How light-based tagging targets pyroglutamate
Amino acids are like Lego blocks—they can be linked together to form complex structures called proteins. Unlike Legos, however, there are only 20 different types of amino acids available to build a protein. Proteins depend ...
Phys.org / A much more sensitive fentanyl detection strip, thanks to physics
Following the beginning of the COVID-19 outbreak, lateral flow assays (LFAs)—the category of test strips in which the presence or lack of a pink line indicates whether a specific molecule, like a drug or a virus, has been ...
Phys.org / Fish gill-inspired panels reveal path to efficient thermal mixing
A fascination with fish gills has led researchers at Cornell to develop a bio-inspired approach to mixing heat and molecules in fluids—findings that could inform future biomedical devices, heat exchangers and soft robotics.
Phys.org / Superconducting quantum processor performs well with significantly less wiring
Quantum computers, computing systems that process information using quantum mechanical effects, could outperform classical computers on some computational tasks. These computers rely on qubits, the basic units of quantum ...
Phys.org / Self-cleaning fabric could eliminate the need for detergent
Detergents may begin their journey by cleaning our clothes, but they end up contaminating the environment, flowing into rivers, ponds, and oceans, where they severely disrupt aquatic animal life. Even after wastewater treatment, ...
Phys.org / Quantum computers could have a fundamental limit after all
The performance of quantum computers could cap out after around 1,000 qubits, according to a new analysis published in the Proceedings of the National Academy of Sciences. Through new calculations, Tim Palmer at the University ...
Phys.org / How soil microbes may control the future of our planet
The soil beneath our feet is a huge carbon bank storing up to approximately three times more carbon than the entire atmosphere. That makes it a significant player in the future of our climate. If even a small fraction of ...
Phys.org / Moby Dick 'ship sinking' sperm whales caught headbutting on camera
New research from the University of St Andrews reports sperm whales headbutting one another. The behavior was captured on film and described scientifically for the first time, confirming accounts by 19th century mariners ...
Phys.org / Discovery of genetic switch could help turn rice into a perennial crop
Rice is a vital crop that feeds more than half of the world's population. In the wild, many rice species are perennials that live for several years, but the varieties we eat today are typically annuals that must be replanted ...
Phys.org / Urban blue tits use discarded cigarette butts to protect their nests, study suggests
Discarded litter not only makes our streets and neighborhoods look untidy, but it can also pose a significant risk to wildlife. However, in a surprising development, a study published in the journal Animal Behaviour reports ...
