Published Looking to the past to prevent future extinction
(via sciencedaily.com) Original source Anthropologists created a computational model to predict the likelihood of animal extinctions based on the complex interaction of hunting and environmental change.
Published Combination of the climate crisis and continued deforestation may result in significant damage to the animal world
(via sciencedaily.com) Original source A new study states that the combination of global warming and extreme heat events, alongside the continued expansion of deforestation in the world, may be devastating for many species of animals, especially those that know how to climb trees. As part of the study, the researchers focused on lizards and showed that following the effects of climate change, they will seek refuge from the hot ground by spending a lot of time on trees. However, due to human-related activities, such as deforestation, urbanization and the expansion of agricultural lands at the expense of natural lands, the availability of trees in the areas where the lizards live will decrease, and this may lead to the collapse of many populations.
Published Biologists uncover new species of tiger beetle: Eunota houstoniana
(via sciencedaily.com) Original source Evolutionary biologists have unearthed a new species of tiger beetle, deemed Eunota houstoniana, honoring the Houston region where it predominantly resides.
Published Evolution of the most powerful ocean current on Earth
(via sciencedaily.com) Original source The Antarctic Circumpolar Current plays an important part in global overturning circulation, the exchange of heat and CO2 between the ocean and atmosphere, and the stability of Antarctica's ice sheets. An international research team has now used sediments taken from the South Pacific to reconstruct the flow speed in the last 5.3 million years. Their data show that during glacial periods, the current slowed; during interglacials, it accelerated. Consequently, if the current global warming intensifies in the future, it could mean that the Southern Ocean stores less CO2 and that more heat reaches Antarctica.
Published Curbside collection improves organic waste composting, reduces methane emissions
(via sciencedaily.com) Original source Most organic household waste ends up in landfills where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming. A new study explores the effects of curbside compost collection programs.
Published Researchers find energy development and tree encroachment impact Wyoming pronghorn
(via sciencedaily.com) Original source While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.
Published In paleontology, correct names are keys to accurate study
(via sciencedaily.com) Original source When the skeletal remains of a giant ground sloth were first unearthed in 1796, the discovery marked one of the earliest paleontological finds in American history.
Published New roadmap to prevent pandemics centers on protecting biodiversity
(via sciencedaily.com) Original source An international team of 25 scientists has proposed a roadmap for how to prevent the next pandemic by conserving natural areas and promoting biodiversity, thereby providing animals with enough food, safe havens and distance to limit contact and the transfer of pathogens to humans.
Published New maps help decision-makers factor albedo into tree-planting decisions
(via sciencedaily.com) Original source A new study provides a global analysis of where restoration of tree cover is most effective at cooling the global climate system, considering not just the cooling from carbon storage but also the warming from decreased albedo. The researchers provide a tool practitioners and land managers can use to determine just how much of a problem albedo is for any reforestation or afforestation project on the globe.
Published Climate change will see Australia's soil emit CO2 and add to global warming
(via sciencedaily.com) Original source New research has shown the warming climate will turn Australia's soil into a net emitter of carbon dioxide (CO2), unless action is taken. Soil helps to keep the planet cool by absorbing carbon, however as the climate gets warmer its ability to retain carbon decreases -- and in some instances can start to release some carbon back into the air. A global research team has predicted the changes in the amount of carbon in Australia's soil between now and the year 2100.
Published Two coral snakes recorded battling for prey in a scientific first
(via sciencedaily.com) Original source Two red-tailed coral snakes have been observed competing over a caecilian in the first documented wild case of kleptoparasitism within the family Elapidae.
Published Crackdown on illicit drugs detects rise in 'designer' drug substitutes
(via sciencedaily.com) Original source As authorities crack down on illicit drugs, experts have issued an alert on the use of the synthetic stimulant pentylone, as new research finds a 75% increase in detections across Australia.
Published Research lights up process for turning CO2 into sustainable fuel
(via sciencedaily.com) Original source Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published Research identifies characteristics of cities that would support young people's mental health
(via sciencedaily.com) Original source As cities around the world continue to draw young people for work, education, and social opportunities, a new study identifies characteristics that would support young urban dwellers' mental health. The findings, based on survey responses from a global panel that included adolescents and young adults, provide a set of priorities that city planners can adopt to build urban environments that are safe, equitable, and inclusive.
Published Pairing crypto mining with green hydrogen offers clean energy boost
(via sciencedaily.com) Original source Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published Global study of coastal seas as carbon dioxide reservoirs
(via sciencedaily.com) Original source Coastal seas form a complex transition zone between the two largest CO2 sinks in the global carbon cycle: land and ocean. Ocean researchers have now succeeded for the first time in investigating the role of the coastal ocean in a seamless model representation.
Published Citizen scientists contribute vital information about 35 seahorse species
(via sciencedaily.com) Original source Thanks to diligent observers, seahorses, those enigmatic and charismatic fish, are not only being discovered in new habitats and expanded geographic ranges, they are also being found at new ocean depths. While their capacity for male pregnancy has long fascinated people, new information on sex ratio and pregnancy seasonality has been discovered.
Published 'Winners and losers' as global warming forces plants uphill
(via sciencedaily.com) Original source Some plant species will 'win' and others will 'lose' as global warming forces them to move uphill, new research shows.
Published Cool paint coatings help pedestrians feel up to 1.5 degrees Celsius cooler in urban setting
(via sciencedaily.com) Original source A real-world study has shown that the use of cool paint coatings in cities can help pedestrians feel up to 1.5 degrees Celsius cooler, making the urban area more comfortable for work and play.
Published A self-cleaning wall paint
(via sciencedaily.com) Original source Beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while -- but over time, the color changes and needs to be renewed. Now, special titanium oxide nanoparticles have been developed that can be added to ordinary, commercially available wall paint to establish self-cleaning power: The nanoparticles are photocatalytically active, they can use sunlight not only to bind substances from the air, but also to decompose them afterwards.
