Scientists unveil fire-safe fuel      (via sciencedaily.com)     Original source 

Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a 'safe' liquid fuel.

Plastic cloud: New study analyzes airborne microplastics in clouds      (via sciencedaily.com)     Original source 

Plastic waste that accumulates on land eventually ends up in the ocean as microplastics. However, it is now speculated that microplastics are also present in the atmosphere, contained in clouds. In a new study, researchers analyzed cloud water samples from high-altitude mountains in Japan to ascertain the amount of microplastics in them. They also shed light on how these airborne particles influence cloud formation and their negative impact on the climate.

Atlantic walrus more vulnerable than ever to Arctic warming      (via sciencedaily.com)     Original source 

Past cycles of climate change, along with human exploitation, have led to only small and isolated stocks of Atlantic walrus remaining. The current population is at high risk of the same issues affecting them severely, according to a new study.

Protecting lands slows biodiversity loss among vertebrates by five times      (via sciencedaily.com)     Original source 

Protecting large swaths of Earth's land can help stem the tide of biodiversity loss -- especially when those protected areas are in less disturbed landscapes and in countries with effective national governance. A new study looked at how amphibians, reptiles, mammals and birds fared in protected versus unprotected areas worldwide. Vertebrate abundance decreased five times more slowly inside protected areas, offering much-needed support for the United Nations' '30 by 30' conservation initiative.

How to save plants from climate change? Just ask them      (via sciencedaily.com) 

Climate change and a range of human-caused factors have disrupted the habitats of many California native trees and other plant species. Efforts to protect or relocate plant species would be bolstered by understanding which habitats are best suited for each species. A new study identified a range of characteristics from more than 100 types of plants that can be analyzed to determine each species' preferred temperature and rainfall amount.

Scientists reveal what fuels wildfires in Sierra Nevada Mountains      (via sciencedaily.com)     Original source 

Wildfires in California, exacerbated by human-driven climate change, are getting more severe. To better manage them, there's a growing need to know exactly what fuels the blazes after they ignite. Scientists now report that one of the chief fuels of wildfires in California's Sierra Nevada mountains is the decades-old remains of large trees.

Theories about the natural world may need to change to reflect human impact      (via sciencedaily.com) 

New research has validated at scale, one of the theories that has underpinned ecology for over half a century. In doing so, the findings raise further questions about whether models should be revised to capture human impacts on natural systems.

Despite being properly treated and highly diluted, wastewater still impacts on the river ecosystem      (via sciencedaily.com)     Original source 

An experiment using water from a large wastewater treatment plant has shown that this water continues to affect river diversity and the trophic web (food web) despite being properly treated and highly diluted before discharge. The study shows that the limits currently in place and the procedures used to treat wastewater may not be sufficient to protect the natural properties of food webs.

Ocean acidification makes ecologically important seaweed species fragile      (via sciencedaily.com)     Original source 

Ocean acidification will likely almost triple by the end of the century -- a drastic environmental change that could impact important marine species like fleshy seaweeds, algae that grow vertically and promote biodiversity in more than a third of the world's coastline. To get a better idea of how seaweeds might fare in a rapidly acidifying ocean, a team of marine scientists subjected a common fleshy seaweed species to the acidification levels expected by the end of the century. They report that increased acidification impacted the seaweed's chemical balance, made both its structure and its tissues weaker, and reduced its overall chances of survival.

Probing the deep genetic structure of Africa      (via sciencedaily.com)     Original source 

Using ancestry decomposition techniques an international research team has revealed a deeply divergent ancestry among admixed populations from the Angolan Namib desert. This unique genetic heritage brings the researchers closer to understanding the distribution of genetic variation in the broader region of southern Africa before the spread of food production.

Efficient fuel-molecule sieving using graphene      (via sciencedaily.com) 

A research team has successfully developed a new method that can prevent the crossover of large fuel molecules and suppress the degradation of electrodes in advanced fuel cell technology using methanol or formic acid. The successful sieving of the fuel molecules is achieved via selective proton transfers due to steric hindrance on holey graphene sheets that have chemical functionalization and act as proton-exchange membranes.

Re-wetting is key for boosting CO2 storage in southern US peatlands      (via sciencedaily.com)     Original source 

Maintaining a water level between 20 and 30 centimeters below the local water table will boost southern peatlands' carbon storage and reduce the amount of greenhouse gases they release back into the atmosphere during dry periods by up to 90%, a new study finds. Applying this guideline on 100,000 acres of restored or partially restored peatlands across the Southeast could reduce U.S. carbon losses by 2% to 3% of our total national goal.

We could sequester CO2 by 're-greening' arid lands, plant scientists say      (via sciencedaily.com)     Original source 

Reducing CO2 levels in the atmosphere will take more than cutting emissions -- we will also need to capture and store the excessive volumes of already-emitted carbon. A team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.

How climate warming could disrupt a deep-rooted relationship      (via sciencedaily.com) 

Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.
