Published Study unlocks the power of visible light for sustainable chemistry
(via sciencedaily.com) Original source A breakthrough in sustainable molecular transformations has been announced. Chemists have developed an important way to harness the power of visible light to drive chemical processes with greater efficiencies, offering a greener alternative to traditional methods.
Published How extratropical ocean-atmosphere interactions can contribute to the variability of jet streams in the Northern Hemisphere
(via sciencedaily.com) Original source Ocean-atmosphere coupling, the exchange in energy between the ocean and atmosphere, influences teleconnection patterns, the climate effects across vast geographical areas. However, its impact outside the tropics is unclear. A group of researchers examined the effect of ocean coupling on atmospheric circulation patterns in the Northern Hemisphere. They found that extratropical ocean-atmosphere coupling enhances teleconnection patterns and causes more meandering westerly jet streams, which are linked to extreme weather events.
Published North American cities may see a major species turnover by the end of the century
(via sciencedaily.com) Original source Climate change may dramatically affect the animal species observed in North American cities, according to a new study.
Published A solar cell you can bend and soak in water
(via sciencedaily.com) Original source Researchers have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed.
Published Rock-wallaby bite size ‘packs a punch’
(via sciencedaily.com) Original source Australian rock-wallabies are 'little Napoleons' when it comes to compensating for small size, packing much more punch into their bite than larger relatives. Researchers made the discovery while investigating how two dwarf species of rock-wallaby are able to feed themselves on the same kinds of foods as their much larger cousins.
Published Scientists warn: The grey seal hunt is too large
(via sciencedaily.com) Original source Researchers warn that today's hunting quotas of about 3,000 animals pose a risk to the long-term survival of the grey seal in the Baltic Sea. The conclusions of this new study are based on statistics from 20th century seal hunting and predictions of future climate change.
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 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 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 Discovery of amino acid unveils how light makes plants open
(via sciencedaily.com) Original source Scientists have uncovered a unique mechanism that regulates the opening of stomata in plants. Phosphorylation of the amino acid Thr881 on the plasma membrane proton pump plays a key role in this process. The study paves the way for the targeted manipulation of plant physiology, with potential applications in agriculture and environmental sustainability.
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 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 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 '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 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.
Published Researchers discover evolutionary 'tipping point' in fungi
(via sciencedaily.com) Original source Scientists have found a 'tipping point' in the evolution of fungi that throttles their growth and sculpts their shapes. The findings demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes.
Published Bees need food up to a month earlier than provided by recommended pollinator plants
(via sciencedaily.com) Original source Plant species which are recommended as 'pollinator friendly' in Europe begin flowering up to a month too late for bees, resulting in low colony survival and low production of queens. This research has quantified the decline in colony survival and queen production due to a shortage of early season food. Enhancing existing hedgerows with early blooming species has the potential to increase the probability that a bee colony survives from 35% to 100%.
