Published Nano-sized cell particles are promising intervention tool in treating infectious diseases
(via sciencedaily.com) Original source Extracellular vesicles were found to inhibit the viral infection of COVID-19 and potentially other infectious diseases.
Published A spectrum of possibilities: Insights into the evolution of far-red light photosynthesis
(via sciencedaily.com) Original source Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could pave the way for engineering plants with enhanced light absorption capabilities and has implications for our search for extraterrestrial life.
Published Scientists harness flower 'super power' to pave the way for new drug treatments
(via sciencedaily.com) Original source Researchers have developed a way of joining up the head and tail of a protein, making it more stable and easier to get into cells.
Published Minimalist or maximalist? The life of a microbe a mile underground
(via sciencedaily.com) Original source Researchers characterize nearly 600 microbial genomes collected from goldmine. The study illuminates 'microbial dark matter' residing below the surface. Microbes divide into two groups: minimalists that have one, specialized job or maximalists that are prepared to use any available resource. Study has implications for how underground activities, like mining and carbon storage, could affect or be affected by microbial life. The lifestyle of these 'intraterrestrial' microbes also provides hints to what organisms could be living on other planets.
Published Slash-and-burn agriculture can increase forest biodiversity, researchers find
(via sciencedaily.com) Original source The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.
Published New material reduces bacterial infection and speeds up bone healing
(via sciencedaily.com) Original source Researchers have developed a new surgical implant that has the potential to transform the treatment of complex bone infections. When implanted on an injured or infected bone, the material can not only speed up bone healing, it also reduces the risk of infections without the need for traditional antibiotics.
Published Scientist discovers potential brain link between stress, emotional eating
(via sciencedaily.com) Original source Scientists describe how they identified a molecule that may trigger over-consumption of comfort foods after a threatening event.
Published Scientists find both potential threats and promising resources in the thriving colonies of bacteria and fungi on ocean plastic trash
(via sciencedaily.com) Original source Scientists have found both potential threats and promising resources in the thriving colonies of bacteria and fungi on plastic trash washed up on shores.
Published Promising salt for heat storage
(via sciencedaily.com) Original source Salt batteries can store summer heat to be used in winter, but which salt works best for the purpose?
Published Sensitive ecosystems at risk from mine waste
(via sciencedaily.com) Original source Nearly a third of the world's mine tailings are stored within or near protected conservation areas, new research has found.
Published Deoxygenation levels similar to today's played a major role in marine extinctions during major past climate change event
(via sciencedaily.com) Original source Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth's history. Their finding has implications for current day ecosystems -- and serves as a warning that marine environments are likely more fragile than apparent. New research, published today in leading international journal Nature Geosciences, suggests that oceanic anoxia played an important role in ecosystem disruption and extinctions in marine environments during the Triassic--Jurassic mass extinction, a major extinction event that occurred around 200 million years ago. Surprisingly however, the study shows that the global extent of euxinia (an extreme form of de-oxygenated conditions) was similar to the present day.
Published Fish IgM structure sheds light on antibody evolution
(via sciencedaily.com) Original source Researchers have analyzed the antibody Immunoglobulin M in rainbow trout to shed some light on why these proteins may have evolved over time.
Published Vampire bats make northward flight seeking stable climates
(via sciencedaily.com) Original source A new article predicts that vampire bats -- currently only found in Mexico and Central and South America -- are on the move, with the United States being a viable home in 27 years.
Published Study provides fresh insights into antibiotic resistance, fitness landscapes
(via sciencedaily.com) Original source A new study suggests that E. coli bacteria may have a higher capability to evolve antibiotic resistance than previously believed. Researchers mapped possible mutations in an essential E. coli protein involved in antibiotic resistance and found that 75% of evolutionary paths led to high antibiotic resistance, challenging existing theories about fitness landscapes in evolutionary biology. This discovery may have broader implications for understanding adaptation and evolution in various fields.
Published New clues into the head-scratching mystery of itch
(via sciencedaily.com) Original source Scientists show for the first time that bacteria can cause itch by activating nerve cells in the skin. The findings can inform new therapies to treat itch that occurs in inflammatory skin conditions like eczema and dermatitis.
Published Revolutionary breakthrough in the manufacture of photovoltaic cells
(via sciencedaily.com) Original source Engineers have achieved a world first by manufacturing the first back-contact micrometric photovoltaic cells.
Published Casas del Turuñuelo, a site of repeated animal sacrifice in Iron Age Spain
(via sciencedaily.com) Original source The Iron Age site of Casas del Turuñuelo was used repeatedly for ritualized animal sacrifice, according to a multidisciplinary study.
Published Hybrid transistors set stage for integration of biology and microelectronics
(via sciencedaily.com) Original source Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
Published How do temperature extremes influence the distribution of species?
(via sciencedaily.com) Original source As the planet gets hotter, animal and plant species around the world will be faced with new, potentially unpredictable living conditions, which could alter ecosystems in unprecedented ways. A new study investigates the importance of temperature in determining where animal species are currently found to better understand how a warming climate might impact where they might live in the future.
Published AI for perovskite solar cells: Key to better manufacturing
(via sciencedaily.com) Original source Tandem solar cells based on perovskite semiconductors convert sunlight to electricity more efficiently than conventional silicon solar cells. In order to make this technology ready for the market, further improvements with regard to stability and manufacturing processes are required. Researchers have succeeded in finding a way to predict the quality of the perovskite layers and consequently that of the resulting solar cells: Assisted by Machine Learning and new methods in Artificial Intelligence (AI), it is possible assess their quality from variations in light emission already in the manufacturing process.
