Published Engineers develop a soft, printable, metal-free electrode
(via sciencedaily.com) Original source Engineers developed a metal-free, Jelly-like material that is as soft and tough as biological tissue and can conduct electricity similarly to conventional metals. The new material, which is a type of high-performance conducting polymer hydrogel, may one day replace metals in the electrodes of medical devices.
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 Energy harvesting via vibrations: Researchers develop highly durable and efficient device
(via sciencedaily.com) Original source An international research group has engineered a new energy-generating device by combining piezoelectric composites with carbon fiber-reinforced polymer (CFRP), a commonly used material that is both light and strong. The new device transforms vibrations from the surrounding environment into electricity, providing an efficient and reliable means for self-powered sensors.
Published Metaverse could put a dent in global warming
(via sciencedaily.com) Original source For many technology enthusiasts, the metaverse has the potential to transform almost every facet of human life, from work to education to entertainment. Now, new research shows it could have environmental benefits, too.
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 First illustration of the molecular machinery that makes cilia beat
(via sciencedaily.com) Original source The first image of the structures that power human cilia -- the tiny, hairlike projections that line our airways -- has now been produced and it could lead to much-needed treatments for people with rare cilial diseases.
Published All-electric rideshare fleet could reduce carbon emissions, increase traffic issues
(via sciencedaily.com) Original source Two major ridesharing companies have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. To understand additional impacts of this transition, researchers conducted life-cycle comparisons of battery-powered electric vehicle fleets to a gas-powered one, using real-world rideshare data. They found up to a 45% reduction in greenhouse gas emissions from full electrification; however, traffic problems and air pollution could increase.
Published Novel ferroelectrics for more efficient microelectronics
(via sciencedaily.com) Original source A team of researchers is exploring novel materials that have potential to make microelectronics more energy efficient. Their recent work explores recently discovered wurtzite ferroelectrics, which are mainly composed of materials that are already incorporated in semiconductor technology for integrated circuits. These materials allow for the integration of new power-efficient devices for applications such as non-volatile memory, electro-optics, and energy harvesting.
Published Megawatt electrical motor designed by engineers could help electrify aviation
(via sciencedaily.com) Original source Aerospace engineers designed a 1-megawatt electrical motor that is a stepping stone toward electrifying the largest aircraft.
Published When water temperatures change, the molecular motors of cephalopods do too
(via sciencedaily.com) Original source Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.
Published Study unravels the mysteries of actin filament polarity
(via sciencedaily.com) Original source An electron microscopy study revealed key details of actin filaments, which are essential structural elements of cells and muscles.
Published Octopuses rewire their brains to adapt to seasonal temperature shifts
(via sciencedaily.com) Original source Octopuses don't thermoregulate, so their powerful brains are exposed to -- and potentially threatened by -- changes in temperature. Researchers report that two-spot octopuses adapt to seasonal temperature shifts by producing different neural proteins under warm versus cool conditions. The octopuses achieve this by editing their RNA, the messenger molecule between DNA and proteins. This rewiring likely protects their brains, and the researchers suspect that this unusual strategy is used widely amongst octopuses and squid.
Published New superconducting diode could improve performance of quantum computers and artificial intelligence
(via sciencedaily.com) Original source A team has developed a more energy-efficient, tunable superconducting diode -- a promising component for future electronic devices -- that could help scale up quantum computers for industry and improve artificial intelligence systems.
Published A compound from fruit flies could lead to new antibiotics
(via sciencedaily.com) Original source Research shows that the natural peptide, called drosocin, protects fruit flies from bacterial infections by binding to ribosomes in bacteria. Once bound, drosocin prevents the ribosome from making new proteins.
Published Muscle fibers: An unexpected organization revealed
(via sciencedaily.com) Original source Researchers have just made the unexpected discovery of a novel organization of muscle fibers in Parophidion vassali, a fish that lives in the Mediterranean Sea and, like many fish, uses specialized muscles to produce sounds. This is an important discovery that could well change our understanding of muscle contraction.
Published New class of antibiotics to fight resistant bacteria
