Published The West is best to spot UFOs
(via sciencedaily.com) Original source Researchers identified environmental factors that explain why reports of Unidentified Anomalous Phenomena (UAP) are more common in certain regions of the country. Most sightings occur in the American West where proximity to public lands, dark skies and military installations afford more opportunities to see strange objects in the air. Understanding the environmental context of these sightings will make it easier to find explanations for their occurrence and help identify truly anomalous objects that may be a legitimate threat.
Published Climate change shrinking fish
(via sciencedaily.com) Original source Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other species for food. During the 2010s, while the number of Japanese sardine and chub mackerel moderately increased, the effect of climate change warming the ocean appears to have resulted in more competition for food, as cooler, nutrient-dense water could not easily rise to the surface. These results have implications for fisheries and policymakers trying to manage ocean resources under future climate change scenarios.
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 Want fewer microplastics in your tap water? Try boiling it first
(via sciencedaily.com) Original source Nano- and microplastics are seemingly everywhere -- water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.
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 How air pollution can harm team performance
(via sciencedaily.com) Original source High levels of air pollution can affect teams doing complex tasks, which holds implications for emerging economies.
Published Researchers are first to see at-risk bat flying over open ocean
(via sciencedaily.com) Original source On a research cruise focused on marine mammals and seabirds, scientists earned an unexpected bonus: The first-ever documented sighting of a hoary bat flying over the open ocean.
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 You may be breathing in more tiny nanoparticles from your gas stove than from car exhaust
(via sciencedaily.com) Original source Cooking on your gas stove can emit more nano-sized particles into the air than vehicles that run on gas or diesel, possibly increasing your risk of developing asthma or other respiratory illnesses, a new study has found.
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 Extinctions could result as fish change foraging behavior in response to rising temperatures
(via sciencedaily.com) Original source Fish species respond to temperature increases by going after more readily available prey. Models suggest this behavior could lead to more extinctions.
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 Scientists propose new method for tracking elusive origins of CO2 emissions from streams
(via sciencedaily.com) Original source A team of researchers that specializes in accounting for the carbon dioxide release by streams, rivers and lakes recently demonstrated that the chemical process known as 'carbonate buffering' can account for the majority of emissions in highly alkaline waters. Furthermore, carbonate buffering distorts the most commonly used method of tracking the origins of CO2 in streams. The research proposes a better method for tracking the origin of riverine CO2 emissions.
Published Latest science shows endocrine disrupting chemicals in plastics, pesticides, and other sources pose health threats globally
(via sciencedaily.com) Original source A report from the world's leading scientific and medical experts on hormone-related health conditions raises new concerns about the profound threats to human health from endocrine disrupting chemicals (EDCs) that are ubiquitous in our surroundings and everyday lives. Everyday exposures to EDCs in the environment may be linked to increasing rates of infertility, diabetes, immune deficiencies, and other serious conditions; Highly Hazardous Pesticides pose ongoing threats.
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 Butterflies mimic each other's flight behavior to avoid predators
(via sciencedaily.com) Original source Researchers have shown that inedible species of butterfly that mimic each others' color patterns have also evolved similar flight behaviors to warn predators and avoid being eaten.
Published What will it take for China to reach carbon neutrality by 2060?
(via sciencedaily.com) Original source To become carbon neutral by 2060, China will have to build eight to 10 times more wind and solar power installations than existed in 2022, according to a new study. Reaching carbon neutrality will also require major construction of transmission lines.
