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 Double trouble at chromosome ends
(via sciencedaily.com) Original source New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought.
Published Change in gene code may explain how human ancestors lost tails
(via sciencedaily.com) Original source A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys.
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 First DNA study of ancient Eastern Arabians reveals malaria adaptation
(via sciencedaily.com) Original source People living in ancient Eastern Arabia appear to have developed resistance to malaria following the appearance of agriculture in the region around five thousand years ago.
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 New discovery shows how cells defend themselves during stressful situations
(via sciencedaily.com) Original source A recent study has unveiled an exciting discovery about how our cells defend themselves during stressful situations. The research shows that a tiny modification in the genetic material, called ac4C, acts as a crucial defender, helping cells create protective storage units known as stress granules. These stress granules safeguard important genetic instructions when the cell is facing challenges. The new findings could help shed light on relevant molecular pathways that could be targeted in disease.
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 Microbial comics: RNA as a common language, presented in extracellular speech-bubbles
(via sciencedaily.com) Original source Decoding the conversations between microbes of hypersaline environments reveals deep insights into the origins of complex life.
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 Human stem cells coaxed to mimic the very early central nervous system
(via sciencedaily.com) Original source The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists.
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.
