Published Hydrogen flight looks ready for take-off with new advances
(via sciencedaily.com) Original source The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.
Published Mapping the world's fungi from air samples
(via sciencedaily.com) Original source Researchers have found that the key to a quick and cost-effective mapping of biodiversity has been right in front of our eyes all along, but at the same time invisible -- i.e., in the air that surrounds us.
Published Air pollution harms pollinators more than pests, study finds
(via sciencedaily.com) Original source Pollinators experienced a 39-percent decline in foraging efficiency after being exposed to elevated air pollution levels. In contrast, plant-eating aphids and other pests were not significantly impacted.
Published Targeted home systems to remove PFAS more cost-effective than system-wide solutions
(via sciencedaily.com) Original source PFAS, the potentially cancer-causing chemicals known as 'forever chemicals', have become an increasing concern in home drinking water. Solutions to reduce the risk of exposure range from mandated municipal-level water treatment to under-the-sink home treatment systems. But are consumers willing to foot the bill for an additional treatment system to help municipalities meet new federal drinking water regulations? Researchers found that they are, if it helps reduce the risk and fits their budget.
Published First ever 3D reconstruction of 52,000-year-old woolly mammoth chromosomes thanks to serendipitously freeze-dried skin
(via sciencedaily.com) Original source An international research team has assembled the genome and 3D chromosomal structures of a 52,000-year-old woolly mammoth -- the first time such a feat has been achieved for any ancient DNA sample. The fossilized chromosomes, which are around a million times longer than most ancient DNA fragments, provide insight into how the mammoth's genome was organized within its living cells and which genes were active within the skin tissue from which the DNA was extracted. This unprecedented level of structural detail was retained because the mammoth underwent freeze-drying shortly after it died, which meant that its DNA was preserved in a glass-like state.
Published Could lead overcome reverse current and advance a green hydrogen economy?
(via sciencedaily.com) Original source Researchers developed a catalyst that enhances the stability of alkaline water electrolysis systems.
Published New study provides enhanced understanding of tropical atmospheric waves
(via sciencedaily.com) Original source Findings has critical implications for predicting extreme weather events such as hurricanes and heavy rainfall.
Published A new species of extinct crocodile relative rewrites life on the Triassic coastline
(via sciencedaily.com) Original source The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.
Published Planted mangroves' ability to store carbon
(via sciencedaily.com) Original source Ecologists have published new findings on how planted mangroves can store up to 70% of carbon stock to that found in intact stands after only 20 years.
Published Mozambican Woodlands could store more than double the carbon previously estimated
(via sciencedaily.com) Original source The capacity of Mozambican woodlands to capture and store carbon is underestimated and potentially undervalued for their protection and restoration, finds new research from an international team of scientists.
Published Research reveals the most complete dinosaur discovered in the UK in a century
(via sciencedaily.com) Original source The most complete dinosaur discovered in the UK in the last 100 years, with a pubic hip bone the size of a 'dinner plate', has been described in a new article.
Published Wolves' return has had only small impact on deer populations in NE Washington
(via sciencedaily.com) Original source Wolves returned to Washington state in 2008. A new study shows that, despite their rising numbers, wolves are not having much of an impact on white-tailed deer, one of their primary prey. Scientists report that the biggest factor shaping white-tailed deer populations in northeast Washington is the quality of habitat available, which is largely determined by human activity. Cougars were second in their impact. Wolves were a distant third.
Published Enhancing live football broadcasts by eliminating camera operator distractions with AI
(via sciencedaily.com) Original source Researchers have developed an end-to-end system to enhance the viewing experience by eliminating visual distractions caused by overlapping camera angles.
Published New period product offers progress in women's health
(via sciencedaily.com) Original source Researchers have created an eco-friendly, blood absorbent biomaterial that improves the performance of menstrual products by minimizing blood leakage and spilling, while also helping prevent infection.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com) Original source New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published The plague may have caused the downfall of the Stone Age farmers
(via sciencedaily.com) Original source Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows.
Published Researchers show promising material for solar energy gets its curious boost from entropy
(via sciencedaily.com) Original source Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).
Published Cutting farm nitrous oxide emissions helps climate and ozone layer
(via sciencedaily.com) Original source Adding crushed basalt rocks and special fertilizers can reduce potent nitrous oxide (N2O) greenhouse gas emissions and help safeguard the stratospheric ozone layer.
Published Researchers examine economic effects on technological advancements of blue hydrogen production
(via sciencedaily.com) Original source Experience from the deployment of blue hydrogen projects will be helpful in lowering future costs of hydrogen production and will remain cost competitive. Additionally, paired with extended tax incentives for carbon sequestration, costs could be significantly reduced further.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
