Published 3D bioprinting advances research on respiratory viruses
(via sciencedaily.com) Original source Researchers develop a microstructured 'artificial lung' model using bioprinting technology.
Published Effective new catalyst brings hope for cleaner energy, wastewater treatment, and green chemistry
(via sciencedaily.com) Original source A catalyst that significantly enhances ammonia conversion could improve wastewater treatment, green chemical and hydrogen production.
Published Microscopy technique 'paves way' for improving understanding of cellular functions
(via sciencedaily.com) Original source Scientists have developed a new way of counting labelled proteins in living cells that could become a standard and valuable tool in the field of biomedical research.
Published Detecting climate change using aerosols
(via sciencedaily.com) Original source Researchers analyzed long-term aerosol satellite observation big data focusing on the Pacific Ocean downwind of China. Using a newly developed metric that considered aerosols as tracers, they detected altered atmospheric transport patterns associated with climate change. They observed that the distance of transboundary air pollution moving east from China had shortened. Thus, long-term satellite-based Earth observations are crucial for early climate change detection and accurate evaluation of this trend.
Published Increasing clinicians' knowledge about climate change's impact on health and healthcare sustainability
(via sciencedaily.com) Original source A novel educational program for clinicians provided a foundation about climate change and the impact of fossil fuel-related pollution on individual health, and how healthcare systems contribute to carbon pollution and can address these challenges.
Published Unlocking the secrets of salt stress tolerance in wild tomatoes
(via sciencedaily.com) Original source As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.
Published Mix of factors prompts owl monkeys to leave their parents
(via sciencedaily.com) Original source There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.
Published How ribosomes in our cells enable protein folding
(via sciencedaily.com) Original source Scientists discovered a role played by ribosomes during the folding of new proteins in cells.
Published Alaskan land eroding faster due to climate change
(via sciencedaily.com) Original source A new study shows that frozen land in Alaska is eroding faster than it can be replaced due to climate change.
Published Viral defense protein speeds up female stem cell production
(via sciencedaily.com) Original source A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.
Published Individuals vary in how air pollution impacts their mood
(via sciencedaily.com) Original source Affective sensitivity to air pollution (ASAP) describes the extent to which affect, or mood, fluctuates in accordance with daily changes in air pollution, which can vary between individuals, according to a new study.
Published Study quantifies air pollution for NYC subway commuters
(via sciencedaily.com) Original source New York City subway commuters who are economically disadvantaged or belong to racial minority groups have the highest exposure to fine particulate matter during their commutes, according to a new study.
Published Work-from-home success might depend on home office setup
(via sciencedaily.com) Original source In a new survey study, Dutch employees who worked from home tended to report higher levels of productivity and less burnout if they were more satisfied with their home office setup. The study also linked more air ventilation in the home office to higher self-reported productivity.
Published Forever chemical pollution can now be tracked
(via sciencedaily.com) Original source Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.
Published When mammoths roamed Vancouver Island
(via sciencedaily.com) Original source Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.
Published Discovering how plants make life-and-death decisions
(via sciencedaily.com) Original source Researchers have discovered two proteins that work in tandem to control an important response to cell stress.
Published Study on planet-warming contrails 'a spanner in the works' for aviation industry
(via sciencedaily.com) Original source Modern commercial aircraft flying at high altitudes create longer-lived planet-warming contrails than older aircraft, a new study has found.
Published Used concrete transformed into new bricks while trapping CO2
(via sciencedaily.com) Original source Researchers have turned concrete from a demolished school building and carbon dioxide (CO2) from the air into new blocks strong enough to build a house with. The process involved grinding the old concrete into powder, reacting it with CO2 from the air, pressurizing it in layers in a mold and finally heating it to form the new block. Instead of making buildings from new concrete only, this technique could offer a way to recycle old materials while also trapping carbon dioxide in the process. The blocks could theoretically be remade again and again, through the same process.
Published Pesticide contamination is more than apple skin deep
(via sciencedaily.com) Original source Pesticides and herbicides are critical to ensuring food security worldwide, but these substances can present a safety risk to people who unwittingly ingest them. Protecting human health, therefore, demands sensitive analytical methods to identify even trace levels of potentially harmful substances. Now, researchers have developed a high-tech imaging method to detect pesticide contamination at low levels, and its application on fruits reveals that current food safety practices may be insufficient.
Published South Florida estuaries warming faster than Gulf of Mexico, global ocean, USF research shows
(via sciencedaily.com) Original source Estuaries in South Florida have experienced rapid warming over the past two decades, including a record-breaking marine heat wave in 2023, research shows. The findings paint a troubling picture for the marine life that calls Florida home. Possible causes include evaporation, water capacity and residence time (the amount of time water spends in an estuary). No single factor has been identified as dominant.
