Published New study highlights feasibility and optimization of ammonia-based power generation for carbon neutrality
(via sciencedaily.com) A research team has evaluated the feasibility of ammonia-based power generation through techno-economic and carbon footprint analyses.
Published Bees struggle to find flowers because of air pollution
(via sciencedaily.com) Original source A new study has found that air pollution is preventing pollinators finding flowers because it degrades the scent.
Published Artificial intelligence could help build pollen jigsaw of present and ancient flora
(via sciencedaily.com) Original source An emerging system which combines rapid imaging with artificial intelligence could help scientists build a comprehensive picture of present and historic environmental change -- by swiftly and accurately analyzing pollen.
Published Beaver activity in the Arctic increases emission of methane greenhouse gas
(via sciencedaily.com) Original source The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.
Published Mums exposed to air pollution give birth to smaller babies, but living in a greener area may mitigate the risks
(via sciencedaily.com) Original source Women exposed to air pollution give birth to smaller babies, according to new research. The research also shows that women living in greener areas give birth to bigger babies and this may help counteract the effects of pollution.
Published Invasive alien species play key role in 60% of global plant and animal extinctions
(via sciencedaily.com) A new report presents major findings on the gravity of impacts from invasive alien species on our planet.
Published New study reveals the power of railroads to buffer coal plants from a carbon emissions tax
(via sciencedaily.com) A new study suggests that railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources.
Published Lack of evidence hampers progress on corporate-led ecosystem restoration
(via sciencedaily.com) An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.
Published Nudging food delivery customers to skip the fork drastically cuts plastic waste, study shows
(via sciencedaily.com) Original source A new study examines how a food-delivery platform in China used 'green nudges' to increase the share of no-cutlery orders by 648 percent. Extending the changes to all of China would reduce 3.26 million metric tons of plastic waste and save 5.44 million trees each year.
Published A finer picture of global migration reveals complex patterns
(via sciencedaily.com) Original source New research shows that socio-economic factors play a larger role in migration than climate.
Published Bursting air bubbles may play a key role in how glacier ice melts
(via sciencedaily.com) Original source New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.
Published Cattle on low-protein rations may need amino acid supplement to boost milk yield
(via sciencedaily.com) Original source When dairy cows are fed diets with reduced protein concentrations -- aimed at decreased environmental nitrogen pollution from their manure such as nitrate leaching, nutrient-laden run-off and ammonia volatilization -- their milk production can suffer. Supplementing the amino acid histidine may help in maintaining, and even increasing, milk and milk-protein yields.
Published First U.S. study of nest temperature impacts on leatherback hatchlings
(via sciencedaily.com) Original source A study shows nest temperatures affect leatherback hatchling shape, performance and nest success. Lower temperatures produced longer hatchlings; highest temperatures produced hatchlings with thicker body depths. Hatchlings from the highest nest temperatures had shorter flippers. Righting response (ability to flip over) scores were significantly lower in hatchlings from hotter nests. Hatchlings that were smaller and/or had a larger body depth struggled to right themselves. The leatherback turtle nests in this study also had an overall lower hatching success (45 percent) than loggerhead (73 percent) and green sea turtles (70 percent).
Published Capturing carbon in savannas: New research examines role of grasses for controlling climate change
(via sciencedaily.com) New research shows that, in addition to trees, humble grasses also play an essential role in capturing carbon.
Published Scientists develop new method to recover high-purity silicon from expired solar panels for upcycling into lithium-ion batteries
(via sciencedaily.com) Scientists have devised an efficient method of recovering high-purity silicon from expired solar panels to produce lithium-ion batteries that could help meet the increasing global demand to power electric vehicles.
Published Stability inspection for West Antarctica shows: marine ice sheet is not destabilized yet, but possibly on a path to tipping
(via sciencedaily.com) Original source Antarctica's vast ice masses seem far away, yet they store enough water to raise global sea levels by several meters. A team of experts has now provided the first systematic stability inspection of the ice sheet's current state. Their diagnosis: While they found no indication of irreversible, self-reinforcing retreat of the ice sheet in West Antarctica yet, global warming to date could already be enough to trigger the slow but certain loss of ice over the next hundreds to thousands of years.
Published Ag tech can cut billions of tons of greenhouse gas emissions
(via sciencedaily.com) Original source As the Earth's human population grows, greenhouse gas emissions from the world's food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions -- reducing more greenhouse gas than food systems add.
Published New research highlights opportunities to protect carbon and communities from forest fires
(via sciencedaily.com) Original source As the climate and wildfire crises have intensified, so too have concerns regarding the loss of carbon captured and stored in forests from decades to centuries of tree growth. A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.
Published Researchers develop highly efficient and stable photoelectrode for water splitting using organic semiconductors
(via sciencedaily.com) A recent study has unveiled a significant breakthrough in photoelectrode development.
Published Switching from harmful to helpful fungi
(via sciencedaily.com) Original source Mold and diseases caused by fungi can greatly impact the shelf life of fruit and vegetables. However, some fungi benefit their hosts by aiding plant survival. Colletotrichum tofieldiae (Ct) is a root mold which typically supports continued plant development even when the plant is starved of phosphorus, an important nutrient for photosynthesis and growth. Researchers studied a unique pathogenic strain of the fungi, called Ct3, which conversely inhibits plant growth.
