Published Researchers create new compound to build space-age antennas
(via sciencedaily.com) Original source In a first-of-its-kind development, researchers have created a new compound that can be used to 3D print telecommunication antennas and other connectivity devices. These 3D printed products, created by combining a two-dimensional compound called MXenes with a polymer, can be used as an alternative for metallic counterparts and can make a vast improvement in communication technology including elements such as antennas, waveguides and filters.
Published Genetic research revealed several new fern species in tropical America
(via sciencedaily.com) Original source Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.
Published A bright idea for recycling rare-earth phosphors from used fluorescent bulbs
(via sciencedaily.com) Original source Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.
Published Bottlenecks and beehives: How an invasive bee colony defied genetic expectations
(via sciencedaily.com) Original source An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be a sign that species under pressure from climate change can be resilient.
Published Study finds drought fuels invasive species after wildfires
(via sciencedaily.com) Original source Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
Published How molecular 'handedness' emerged in early biology
(via sciencedaily.com) Original source Chemists fill a major gap in origin-of-life theories.
Published Researchers develop novel method to photosynthesize hydrogen peroxide using water and air
(via sciencedaily.com) Original source Researchers have developed a microporous covalent organic framework with dense donor-acceptor lattices and engineered linkages for the efficient and clean production of hydrogen peroxide through the photosynthesis process with water and air.
Published Light stimulates a new twist for synthetic chemistry
(via sciencedaily.com) Original source Molecules that are induced by light to rotate bulky groups around central bonds could be developed into photo-activated bioactive systems, molecular switches, and more.
Published Vest can detect earlier signs of heart muscle disease
(via sciencedaily.com) Original source A reusable vest that can map the electric impulses of the heart in fine detail could detect abnormalities from a potentially fatal heart disease much earlier than is currently possible, a new study suggests.
Published Nanocarrier with escape reflex
(via sciencedaily.com) Original source Protein-based drugs must be transported into cells in a way that prevents their immediate degradation. A new approach is intended to ensure that they remain intact only in certain cells, such as cancer cells. A Japanese research team has introduced a nanocarrier that can 'escape' from endosomes before its cargo is destroyed there. This ability to escape is only triggered within the endosomes of certain tumor cells.
Published New disease testing component facilitates lower-cost diagnostics
(via sciencedaily.com) Original source Biomedical researchers have developed a new, less expensive way to detect nuclease digestion -- one of the critical steps in many nucleic acid sensing applications, such as those used to identify COVID-19 and other infectious diseases.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops
(via sciencedaily.com) Original source In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published Visual prosthesis simulator offers a glimpse into the future
(via sciencedaily.com) Original source Researchers have developed a simulator that enables artificial visual observations for research into the visual prosthesis. This open source tool is available to researchers and offers those who are interested insight into the future application.
Published Researchers use Hawk supercomputer and lean into imperfection to improve solar cell efficiency
(via sciencedaily.com) Original source Solar energy is one of the most promising, widely adopted renewable energy sources, but the solar cells that convert light into electricity remains a challenge. Scientists have turned to the High-Performance Computing Center Stuttgart to understand how strategically designing imperfections in the system could lead to more efficient energy conversion.
Published AI-driven lab speeds catalysis research
(via sciencedaily.com) Original source Researchers have developed a 'self-driving' lab that uses artificial intelligence (AI) and automated systems to provide in-depth analyses of catalytic reactions used in chemical research and manufacturing. The new tool, called Fast-Cat, can provide more information in five days than is possible in six months of conventional testing.
Published Cutting-edge 'protein lawnmower' created
(via sciencedaily.com) Original source Scientists have designed the first synthetic protein-based motor which harnesses biological reactions to fuel and propel itself. 'Imagine if a Roomba could be powered only by the dirt it picks up,' says one of the authors of the study. The motor uses the digestive enzyme trypsin to cut the peptides and convert them into the energy it needs to propel itself.
Published Black carbon sensor could fill massive monitoring gaps
(via sciencedaily.com) Original source Black carbon is up to 25 times more hazardous to human health than other airborne particles of a similar size. Standard sensors are expensive and burdensome, resulting in sparse coverage in regions infamous for poor air quality, such as the greater Salt Lake City area. A University of Utah-led study found that a portable, more affordable sensor recorded black carbon concentrations as accurately as the most widely used instrument for monitoring black carbon in real time. The portable sensor could help expand an accurate observation network to establish disease risk and create effective public health policies.
Published A new, comprehensive roadmap for the future of biomedical engineering
(via sciencedaily.com) Original source Experts published a detailed position paper on the field of biomedical engineering which lays the foundation for a concerted worldwide effort to achieve technological and medical breakthroughs.
Published A new theoretical development clarifies water's electronic structure
(via sciencedaily.com) Original source Scientists have decoded the electronic structure of water, opening up new perspectives for technological and environmental applications.
Published Birds and bee lessons as Pacific field trips also solve 'Michener's mystery'
(via sciencedaily.com) Original source Eight new Pacific bee species and new insights into Fijian bird behaviour on Viti Levu Island have been described in new scientific studies. The research highlights the potential for species discovery, ecological and conservation knowledge and cultural engagement from Asia-Pacific research collaborations.
