Published Understanding climate mobilities: New study examines perspectives from South Florida practitioners
(via sciencedaily.com) Original source A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.
Published From NYC to DC and beyond, cities on the East Coast are sinking
(via sciencedaily.com) Original source Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.
Published Reducing inequality is essential in tackling climate crisis, researchers argue
(via sciencedaily.com) Original source Promoting climate-friendly behaviors will be more successful in societies where everyone has the capacity: financially, physically, and time-wise, to make changes.
Published 'Nutritional quality must be at the heart of climate smart agriculture' -- researchers
(via sciencedaily.com) Original source Farmers in sub-Saharan Africa need to diversify away from growing maize and switch to crops that are resilient to climate change and supply enough key micronutrients for the population, according to a major research study. Maize is a staple crop across the region -- where it is grown and consumed in vast quantities.
Published Global warming intensifies typhoon-induced extreme precipitation over East Asia
(via sciencedaily.com) Original source Scientists use a 3km high-resolution climate model to reveal expanded extreme rainfall from typhoons.
Published Unraveling the mysteries of fog in complex terrain
(via sciencedaily.com) Original source While fog presents a major hazard to transportation safety, meteorologists have yet to figure out how to forecast it with the precision they have achieved for precipitation, wind and other stormy events. This is because the physical processes resulting in fog formation are extremely complex, Now researchers report their findings from an intensive study centered on a northern Utah basin and conceived to investigate the life cycle of cold fog in mountain valleys.
Published In coastal communities, sea level rise may leave some isolated
(via sciencedaily.com) Original source Amid the threat of dramatic sea level rise, coastal communities face unprecedented dangers, but a new study reveals that as flooding intensifies, disadvantaged populations will be the ones to experience some of the most severe burdens of climate change.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought
(via sciencedaily.com) Original source Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published Electronic 'soil' enhances crop growth
(via sciencedaily.com) Original source Barley seedlings grow on average 50% more when their root system is stimulated electrically through a new cultivation substrate. Researchers have now developed an electrically conductive 'soil' for soil-less cultivation, known as hydroponics.
Published New material allows for better hydrogen-based batteries and fuel cells
(via sciencedaily.com) Original source Researchers have developed a solid electrolyte for transporting hydride ions at room temperature. This breakthrough means that the full advantages of hydrogen-based solid-state batteries and fuel cells can be had without the need for constant hydration. This will reduce their complexity and cost, which is essential for advancing towards a practical hydrogen-based energy economy.
Published Big impacts from small changes in cell
(via sciencedaily.com) Original source Tiny things matter -- for instance, one amino acid can completely alter the architecture of the cell. Researchers have now investigated the structure and mechanics of the main component of the cytoskeleton of the cell: a protein known as actin. Actin is found in all living cells where it has a range of important functions -- from muscle contraction to cell signalling and cell shape. This protein comes in two different varieties termed 'isoforms', which are known as gamma actin and beta actin.
Published How jellyfish regenerate functional tentacles in days
(via sciencedaily.com) Original source At about the size of a pinkie nail, the jellyfish species Cladonema can regenerate an amputated tentacle in two to three days -- but how? Regenerating functional tissue across species, including salamanders and insects, relies on the ability to form a blastema, a clump of undifferentiated cells that can repair damage and grow into the missing appendage. Jellyfish, along with other cnidarians such as corals and sea anemones, exhibit high regeneration abilities, but how they form the critical blastema has remained a mystery until now.
Published How technology and economics can help save endangered species
(via sciencedaily.com) Original source A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published Researchers map how measles virus spreads in human brain
(via sciencedaily.com) Original source Researchers mapped how the measles virus mutated and spread in the brain of a person who succumbed to a rare, lethal brain disease. New cases of this disease, which is a complication of the measles virus, may occur as measles reemerges among the unvaccinated, say researchers.
Published GPCR structure: Research reveals molecular origins of function for a key drug target
(via sciencedaily.com) Original source Scientists reveal how G protein-coupled receptors, major therapeutic drug targets, decode critical properties of their ligands.
Published New tool unifies single-cell data
(via sciencedaily.com) Original source A new methodology that allows for the categorization and organization of single-cell data has been launched. It can be used to create a harmonized dataset for the study of human health and disease.
Published Location, location, location: The hidden power of intracellular neighborhoods
(via sciencedaily.com) Original source New findings provide details about the hidden organization of the cytoplasm, showing it makes a big difference where in that cellular broth that messenger RNA (mRNA) get translated into proteins. The findings hold promise for increasing or altering the production of proteins in mRNA vaccines and therapies.
Published The future of canine stem cell therapy: unprecedented, painless, and feeder-free
(via sciencedaily.com) Original source Scientists have developed an efficient, non-invasive, and pain-free method to generate canine-induced pluripotent stem cells (iPSCs). They identified six reprogramming genes that can boost canine iPSC generation by 120 times compared to conventional methods using fibroblasts. The iPSCs were created from urine-derived cells without the need for feeder cells, an impossible feat until now. Their findings are expected to advance regenerative medicine and genetic disease research in veterinary medicine.
Published The key mechanism to cell growth has been elucidated
(via sciencedaily.com) Original source Researchers have discovered how amino acids activate a key cell, TORC1, which is a master regulator in living organisms that controls whether cells grow or recycle their contents in yeast. Notably, the team found that the amino acid cysteine is sensed by a protein called Pib2 and that the two bind together to trigger TORC1. This is important because faulty TORC1 has been linked to disease such as cancer.
Published Novel catalyst system for CO2 conversion
(via sciencedaily.com) Original source Researchers are constantly pushing the limits of technology by breaking new ground in CO2 conversion. Their goal is to turn the harmful greenhouse gas into a valuable resource. A novel catalyst system could help reach that goal.
