Published Fungal genetics could help develop novel biotechnologies
(via sciencedaily.com) Original source An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in the biotech industry.
Published Engineering the next generation of cell and gene therapies
(via sciencedaily.com) Original source Investigators are developing a novel way to treat amyotrophic lateral sclerosis (ALS) and retinitis pigmentosa using engineered stem cells that may eventually lead to personalized treatments.
Published Water arsenic including in public water is linked to higher urinary arsenic totals among the U.S. population
(via sciencedaily.com) Original source A new study shows that water arsenic levels are linked to higher urinary arsenic among the U.S. population for users of both private wells and public water systems.
Published Research collaboration aims to improve nationwide water quality, restore wetlands
(via sciencedaily.com) Original source The new classification system demonstrates the effects wetlands have on water quality at a continental scale -- invaluable data that can be used to better define whether wetlands are federally regulated under the U.S. Clean Water Act.
Published Recycling lake sediments for crop production: A sustainable solution for closing the phosphorus cycle
(via sciencedaily.com) Original source A four-year field experiment conducted on the shores of restored Lake Mustijärv in Viljandi, Estonia, has revealed that recycling phosphorus-rich lake sediments back to agriculture could have positive impacts on crop production.
Published Polar ice sheet melting records have toppled during the past decade
(via sciencedaily.com) Original source The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record. The melting ice sheets now account for a quarter of all sea level rise -- a fivefold increase since the 1990's -- according to researchers who have combined 50 satellite surveys of Antarctica and Greenland taken between 1992 and 2020, funded by NASA and the European Space Agency.
Published Immediate carbon cuts, common marine heatwave terminology urged
(via sciencedaily.com) Original source Oceanographers provide a reality check on the limitations of carbon dioxide removal and a warning that marine heatwaves need clear definitions so communities can adapt.
Published Companies' zero-deforestation commitments have potential to halve cattle-driven deforestation in Brazilian Amazon
(via sciencedaily.com) Original source Study shows better adoption and implementation of company supply chain policies for Brazilian beef and leather could significantly reduce carbon emissions.
Published Scientists identify 2022 sea urchin killer
(via sciencedaily.com) Original source A team of researchers has identified a single-celled organism called a ciliate as the cause of a massive die-off event to a marine animal vital to coral reef health.
Published A once-stable glacier in Greenland is now rapidly disappearing
(via sciencedaily.com) Original source As climate change causes ocean temperatures to rise, one of Greenland's previously most stable glaciers is now retreating at an unprecedented rate, according to a new study.
Published Simple addition to corn bran could boost grain's nutritional value 15-35%
(via sciencedaily.com) Original source What if, by adding a couple of cell layers inside a corn kernel, the grain could become significantly richer in essential nutrients like iron, zinc, and protein? Such an improvement could benefit people who rely on corn for a large portion of their diet, as in many parts of the global south.
Published Study links 'stuck' stem cells to hair turning gray
(via sciencedaily.com) Original source Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.
Published Loops, flags and tension in DNA
(via sciencedaily.com) Original source Two protein complexes carry the major responsibility for the spatial organization of chromosomes in our cell nuclei. DNA tension plays a surprising role in this. Nanoscientists now publish how they have visualized this.
Published New mechanism for DNA folding
(via sciencedaily.com) Original source A hitherto unknown mechanism for DNA folding is described in a new study. The findings provide new insights into chromosomal processes that are vital to both normal development and to prevent disease.
Published Organic beekeeping rivals conventional methods for bee health, productivity
(via sciencedaily.com) Original source Honey bee colonies managed using organic methods were as healthy and productive as those managed in conventional systems, while avoiding the use of synthetic pesticides to control pests and pathogens inside the hive, according to entomologists.
Published Stronger paper bags, reused repeatedly then recycled for biofuel could be future
(via sciencedaily.com) Original source As the world searches for ways to reduce the use of plastics such as single-use plastic bags, a novel study demonstrates a process to make paper bags stronger -- especially when they get wet -- to make them a more viable alternative.
Published Novel nanocages for delivery of small interfering RNAs
(via sciencedaily.com) Original source Small interfering RNAs (siRNAs) are novel therapeutics that can be used to treat a wide range of diseases. This has led to a growing demand for selective, efficient, and safe ways of delivering siRNA in cells. Now, in a cooperation between the Universities of Amsterdam and Leiden, researchers have developed dedicated molecular nanocages for siRNA delivery. In a paper just out in the Journal Chem they present nanocages that are easy to prepare and display tuneable siRNA delivery characteristics.
Published World's climate plans make for a worrying read
(via sciencedaily.com) Original source CLIMATE According to the climate plans submitted to the UN by 50 countries, 12 gigatons of CO2 per year will continue to be emitted by 2050 -- and need to be removed from the atmosphere. Among other things, countries are betting on technology and nature restoration to solve the problem of residual emissions. Researchers describe this as worrying. The researchers recommend rapid reductions here and now.
Published Fluorescent blue coumarins in a folk-medicine plant could help us see inside cells
(via sciencedaily.com) Original source Plants that glow under ultraviolet (UV) light aren't only a figment of science fiction TV and movies. Roots of a traditional medicine plant called the orange climber, or Toddalia asiatica, can fluoresce an ethereal blue hue. And now, researchers have identified two coumarin molecules that could be responsible. These natural coumarins have unique fluorescent properties, and one of the compounds could someday be used for medical imaging.
Published Next decade decisive for PV growth on the path to 2050
(via sciencedaily.com) Original source Global experts on solar power strongly urge a commitment to the continued growth of photovoltaic (PV) manufacturing and deployment to power the planet, arguing that lowballing projections for PV growth while waiting for a consensus on other energy pathways or the emergence of technological last-minute miracles 'is no longer an option.'
