Published Feathered friends can become unlikely helpers for tropical coral reefs facing climate change threat
(via sciencedaily.com) Original source Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs. However, there may be hope for some tropical reefs in the form of feathered friends. A new study has found that the presence of seabirds on islands adjacent to tropical coral reefs can boost coral growth rates on those reefs by more than double.
Published Baboons in captivity in Ancient Egypt: insights from collection of mummies
(via sciencedaily.com) Original source Baboons were raised in captivity before being mummified in Ancient Egyptian sites, according to a new study.
Published Climate change shown to cause methane to be released from the deep ocean
(via sciencedaily.com) Original source New research has shown that fire-ice -- frozen methane which is trapped as a solid under our oceans -- is vulnerable to melting due to climate change and could be released into the sea.
Published Greenhouse gases in oceans are altered by climate change impact on microbes
(via sciencedaily.com) Original source The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.
Published The ocean may be storing more carbon than estimated in earlier studies
(via sciencedaily.com) Original source The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report. Scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed. Plankton gobble up carbon dioxide and, as they grow, convert it into organic tissue via photosynthesis.
Published Plant nurseries are exacerbating the climate-driven spread of 80% of invasive species
(via sciencedaily.com) Original source Researchers have provided detailed maps of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.
Published Top 10 climate science insights unveiled
(via sciencedaily.com) Original source A new report equips policymakers with the latest and most pivotal climate science research from the previous 18 months, synthesized to help inform negotiations at COP28 and policy implementation through 2024 and beyond.
Published Harvesting water from air with solar power
(via sciencedaily.com) Original source Researchers have developed a promising new solar-powered atmospheric water harvesting technology that could help provide enough drinking water for people to survive in difficult, dryland areas: They synthesized a super hygroscopic gel capable of absorbing and retaining an unparalleled amount of water. One kilogram of dry gel could adsorb 1.18 kilograms of water in arid atmospheric environments and up to 6.4 kilograms in humid atmospheric environments. This hygroscopic gel was simple and inexpensive to prepare and would consequently be suitable for large-scale preparation.
Published Using AI to find microplastics
(via sciencedaily.com) Original source An interdisciplinary research team is using artificial intelligence (AI) to identify microplastics faster and more accurately than ever before.
Published 'Shocking' discovery: Electricity from electric eels may transfer genetic material to nearby animals
(via sciencedaily.com) Original source Researchers have discovered that electric eels can alter the genes of tiny fish larvae with their electric shock. Their findings help to better understand electroporation, a method by which genes can be transported using electricity.
Published Wildfires have erased two decades' worth of air quality gains in western United States
(via sciencedaily.com) Original source A new study concludes that wildfires originating in the western United States and Canada have erased air quality gains over the past two decades and caused an increase of premature deaths in fire-prone areas and downwind regions, primarily in the western U.S.
Published Fossil CO2 emissions at record high in 2023
(via sciencedaily.com) Original source Global carbon emissions from fossil fuels have risen again in 2023 -- reaching record levels, according to new research.
Published In hotter regions, mammals seek forests, avoid human habitats
(via sciencedaily.com) Original source As the climate warms, preserving forest cover will be increasingly important for wildlife conservation, finds a study of North American mammals.
Published New study identifies the greatest threat to wildlife across North America and Canada: people
(via sciencedaily.com) Original source A biology student studied more than 600,000 wildlife rehabilitation center records to look at the human impact on wild animals, from lead poisonings to window strikes to vehicle collisions.
Published 1.5°C pathways can still be achieved, combining fairness and global climate protection
(via sciencedaily.com) Original source Global warming can still be limited to 1.5°C by 2100 while ensuring that the poor are not hit hardest by climate policies and climate impacts. This is achieved by immediately introducing broad carbon pricing together with re-distributive policies using carbon pricing revenues and further measures to reduce energy consumption, accelerate technological transitions, and transform the land sector.
Published How mountains affect El Niño-induced winter precipitation
(via sciencedaily.com) Original source A consideration of how mountains influence El Niño and La Niña-induced precipitation change in western North America may be the ticket to more informed water conservation planning along the Colorado River, new research suggests.
Published Snail-inspired robot could scoop ocean microplastics
(via sciencedaily.com) Original source Inspired by a small and slow snail, scientists have developed a robot protype that may one day scoop up microplastics from the surfaces of oceans, seas and lakes.
Published Artificial light is luring birds to cities and sometimes to their deaths
(via sciencedaily.com) Original source Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.
Published More than a meteorite: New clues about the demise of dinosaurs
(via sciencedaily.com) Original source What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.
Published Researchers decode aqueous amino acid's potential for direct air capture of CO2
(via sciencedaily.com) Original source Scientists have made a significant stride toward understanding a viable process for direct air capture, or DAC, of carbon dioxide from the atmosphere. This DAC process is in early development with the aim of achieving negative emissions, where the amount of carbon dioxide removed from the envelope of gases surrounding Earth exceeds the amount emitted.
