Published Combining twistronics with spintronics could be the next giant leap in quantum electronics
(via sciencedaily.com) Original source Quantum researchers twist double bilayers of an antiferromagnet to demonstrate tunable moiré magnetism.
Published Groundwork for future ultra-precise timing links to geosynchronous satellites
(via sciencedaily.com) Original source Scientists have demonstrated a capability long sought by physicists: transmitting extremely precise time signals through the air between far-flung locations at powers that are compatible with future space-based missions. The results could enable time transfer from the ground to satellites in geosynchronous orbit with femtosecond precision -- 10,000 times better than the existing state-of-the-art satellite approaches. It also would allow for successful synchronization using the bare minimum timing signal strength, which would make the system highly robust in the face of atmospheric disturbances.
Published Researchers reveal mechanism of protection against breast and ovarian cancer
(via sciencedaily.com) Original source Researchers have outlined the structure and function of a protein complex which is required to repair damaged DNA and protect against cancer.
Published Scientists discover new embryonic cell type that self-destructs to protect the developing embryo
(via sciencedaily.com) Original source Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos.
Published Completing genome of rusty patched bumble bee may offer new approach to saving endangered bee
(via sciencedaily.com) Original source A detailed, high-resolution map of the rusty patched bumble bee's genome has been released, offering new approaches for bringing the native pollinator back from the danger of extinction. Putting together the rusty patched bumble bee genome is part of the Beenome 100 project, a first-of-its-kind effort to create a library of high-quality, highly detailed genome maps of 100 or more diverse bee species found in the United States.
Published Cryo conservation: A cool solution to saving species from extinction
(via sciencedaily.com) Original source In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.
Published A new tool to study complex genome interactions
(via sciencedaily.com) Original source Genome Architecture Mapping captures complex, multi-way interactions in the genome. This is different than the workhorse technique of 3D genomics, which sees mostly two-way contacts, finds a new study.
Published From cross to self-pollination
(via sciencedaily.com) Original source Biologists provide evidence for an alternative genetic mechanism that can lead to plants becoming self-pollinators.
Published Tethering of shattered chromosomal fragments paves way for new cancer therapies
(via sciencedaily.com) Original source Scientists discover shattered chromosomal fragments are tethered together during cell division before being rearranged; destroying the tether may help prevent cancerous mutations.
Published Close up on aging reveals how different cell types in the body age at different pace
(via sciencedaily.com) Original source A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.
Published Photosynthesis, key to life on Earth, starts with a single photon
(via sciencedaily.com) Original source A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes.
Published For experimental physicists, quantum frustration leads to fundamental discovery
(via sciencedaily.com) Original source A team of physicists recently announced that they have discovered a new phase of matter. Called the 'chiral bose-liquid state,' the discovery opens a new path in the age-old effort to understand the nature of the physical world.
Published Metamaterials with built-in frustration have mechanical memory
(via sciencedaily.com) Original source Researchers have discovered how to design materials that necessarily have a point or line where the material doesn't deform under stress, and that even remember how they have been poked or squeezed in the past. These results could be used in robotics and mechanical computers, while similar design principles could be used in quantum computers.
Published New technique in error-prone quantum computing makes classical computers sweat
(via sciencedaily.com) Original source Today's quantum computers often calculate the wrong answer because of noisy environments that interfere with the quantum entanglement of qubits. IBM Quantum has pioneered a technique that accounts for the noise to achieve reliable results. They tested this error mitigation strategy against supercomputer simulations run by physicists, and for the hardest calculations, the quantum computer bested the supercomputer. This is evidence for the utility of today's noisy quantum computers for performing real-world calculations.
Published Elimination of type of bacteria suggests treatment for endometriosis
(via sciencedaily.com) Original source A research group has discovered that using an antibiotic to target Fusobacterium, a common bacterium that causes inflammation, improved the symptoms of endometriosis. Their findings suggest an alternative treatment for the disease.
Published Scientists discover small RNA that regulates bacterial infection
(via sciencedaily.com) Original source Researchers have identified the major mechanism behind the transition between chronic and acute P. aeruginosa infections. Their research findings can inform the development of future treatments for life-threatening acute infections.
Published Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved
(via sciencedaily.com) Original source Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.
