Published Rising mercury pollution in soil could be related to climate change
(via sciencedaily.com) Original source In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. The study estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more.
Published Could manure and compost act like probiotics, reducing antibiotic resistance in urban soils?
(via sciencedaily.com) Original source Research suggests that, in some cases, boosting urban soil health with compost and treated manure may reduce the amount of pathogenic and anti-biotic resistant bacteria.
Published Newly discovered ability of comammox bacteria could help reduce nitrous oxide emissions in agriculture
(via sciencedaily.com) Original source An international research team has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source. This unique ability opens new avenues for targeted cultivation of these enigmatic microbes and could also provide a key to reducing agricultural nitrous oxide emissions.
Published Climate change raised the odds of unprecedented wildfires in 2023-24
(via sciencedaily.com) Original source Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.
Published Scientists achieve more than 98% efficiency removing nanoplastics from water
(via sciencedaily.com) Original source Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.
Published Chemists synthesize plant-derived molecules that hold potential as pharmaceuticals
(via sciencedaily.com) Original source Chemists developed a way to synthesize complex molecules called oligocyclotryptamines, originally found in plants, which could hold potential as antibiotics, analgesics, or anticancer drugs.
Published Halogen bonding for selective electrochemical separation, path to sustainable chemical processing demonstrated
(via sciencedaily.com) Original source A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen atom when electricity is applied. The polymer then attracts only certain targets -- such as halides, oxyanions, and even organic molecules -- from organic solutions, a feature that has important implications for pharmaceuticals and chemical synthesis processes.
Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts
(via sciencedaily.com) Original source A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
Published Changing food consumers' choices may help cut greenhouse gases
(via sciencedaily.com) Original source Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets.
Published Expansion of agricultural land threatens climate and biodiversity
(via sciencedaily.com) Original source Food, feed, fiber, and bioenergy: The demand for agricultural raw materials is rising. How can additional cultivation areas be reconciled with nature conservation? Researchers have developed a land-use model that provides answers.
Published Protecting surf breaks mitigates climate change, helps coastal communities
(via sciencedaily.com) Original source Safeguarding places to hang ten and shoot the curl is an opportunity to simultaneously mitigate climate change, fuel tourism and help surrounding ecosystems, research has shown.
Published Reduce, reuse, 're-fly-cle'
(via sciencedaily.com) Original source Black soldier flies are now commercially used to consume organic waste -- but genetic modifications proposed by bioscientists could see the insects digesting a wider variety of refuse, while also creating raw ingredients for industry.
Published Ships now spew less sulfur, but warming has sped up
(via sciencedaily.com) Original source New findings document fewer ship tracks, reduced cloud cover, and boosted warming after ship emissions regulations took effect in 2020.
Published New study unveils 16,000 years of climate history in the tropical Andes
(via sciencedaily.com) Original source Researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.
Published Forest restoration can boost people, nature and climate simultaneously
(via sciencedaily.com) Original source Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
Published Why carbon nanotubes fluoresce when they bind to certain molecules
(via sciencedaily.com) Original source Nanotubes can serve as biosensors. They change their fluorescence when they bind to certain molecules. Until now, it was unclear why. Researchers have gained new insights into the cause of the fluorescence.
Published Mature forests vital in frontline fight against climate change
(via sciencedaily.com) Original source Mature forests have a key role to play in the fight against climate change -- extracting carbon dioxide (CO2) from the atmosphere and locking it into new wood.
Published Balancing technology and governance are key to achieving climate goals
(via sciencedaily.com) Original source Despite advancements in clean energy, global CO2 emissions continue to rise. IIASA researchers contributed to a new international study that underscores the importance of integrating technological advancements with robust institutional capacities to formulate effective climate policies.
Published Drug protects against air pollution-related Alzheimer's signs in mice
(via sciencedaily.com) Original source A new study shows how feeding mice a drug called GSM-15606 provided protection against air pollution-related increases in proteins linked to Alzheimer's disease.
Published Just say 'climate change' -- not 'climate emergency'
(via sciencedaily.com) Original source The familiar terms 'climate change' and 'global warming' are more likely to resonate with people than other commonly used phrases.
