Published The future is foggy for Arctic shipping
(via sciencedaily.com)
Original source 
As the Arctic warms and loses sea ice, trans-Arctic shipping has increased, reducing travel time and costs for international trade. However, a new study finds that the Arctic Ocean is getting foggier as ice disappears, reducing visibility and causing costly delays as ships slow to avoid hitting dangerous sea ice.
Published Early-nesting ducks at increased risk due to changes in climate, land use
(via sciencedaily.com)
Original source 
Each year approximately 10 million waterfowl fly north to their breeding grounds in the Prairie Pothole Region of North America, but the landscape that greets them has changed. Weather patterns and agricultural practices have significantly transformed the pothole-dotted native grasslands that waterfowl have used for thousands of years.
Published Scientists discover antibiotic resistance genes in clouds
(via sciencedaily.com)
Original source 
The atmosphere is a large-scale dissemination route for bacteria carrying antibiotic-resistance genes. A research team has shown that these genes can be transported by clouds.
Published Using microbes to get more out of mining waste
(via sciencedaily.com)
Original source 
Researchers have developed a new mining technique which uses microbes to recover metals and store carbon in the waste produced by mining. Adopting this technique of reusing mining waste, called tailings, could transform the mining industry and create a greener and more sustainable future.
Published Is the ocean a solution for ushering in the era of environmentally friendly energy?
(via sciencedaily.com)
Original source 
Researchers confirm the superiority of seawater batteries that use chelating agents.
Published Twilight zone at risk from climate change
(via sciencedaily.com)
Original source 
Life in the ocean's 'twilight zone' could decline dramatically due to climate change, new research suggests.
Published Chemists tackle the tough challenge of recycling mixed plastics
(via sciencedaily.com)
Original source 
Polymer chemists have been finding ways to tackle the environmental problems humans have created with plastics waste. Now, a team has come up with fundamental new chemistry that seeds a creative solution to the challenge of recycling mixed-use plastics.
Published How the Amazon rainforest is likely to cope with the effect of future drought
(via sciencedaily.com)
Original source 
A major collaboration involving 80 scientists from Europe and South America has identified the regions of the Amazon rainforest where trees are most likely to face the greatest risk from drier conditions brought about by climate change. Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.
Published New chemistry can extract virgin-grade materials from wind turbine blades in one process
(via sciencedaily.com)
Original source 
Researchers have developed a chemical process that can disassemble the epoxy composite of wind turbine blades and simultaneously extract intact glass fibers as well as one of the epoxy resin's original building blocks in a high quality. The recovered materials could potentially be used in the production of new blades.
Published Humidity may increase heat risk in urban climates
(via sciencedaily.com)
Original source 
A new study investigated the combined effect of temperature and humidity on urban heat stress using observational data and an urban climate model calculation. Researchers found that the heat stress burden is dependent on local climate and a humidifying effect can erase the cooling benefits that would come from trees and vegetation.
Published Robot fish makes splash with motion breakthrough
(via sciencedaily.com)
Original source 
A coil-powered robot fish could make underwater exploration more accessible.
Published Mixing theory, observation to envision warmer world
(via sciencedaily.com)
Original source 
A more realistic look at what a hot summer can bring to a nearby pond, and new respect for the blinding speed global warming is bringing.
Published Ocean ecosystem: Mixotrophic microorganisms play key role
(via sciencedaily.com)
Original source 
Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in the marine layer between 200 and 1000 meters.
Published Mysterious underwater acoustic world of British ponds revealed in new study
(via sciencedaily.com)
Original source 
The previously hidden and diverse underwater acoustic world in British ponds has been uncovered by a team of researchers.
Published CO2 recycling: What is the role of the electrolyte?
(via sciencedaily.com)
Original source 
The greenhouse gas carbon dioxide can be converted into useful hydrocarbons by electrolysis. The design of the electrolysis cell is crucial in this process. The so-called zero-gap cell is particularly suitable for industrial processes. But there are still problems: The cathodes clog up quickly.
Published Jellyfish-like robots could one day clean up the world's oceans
(via sciencedaily.com)
Original source 
Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
Published Progress in alternative battery technology
(via sciencedaily.com)
Original source 
It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers have now succeeded in uniting all of these characteristics in zinc metal batteries.
Published Treating polluted water with nanofiber membranes
(via sciencedaily.com)
Original source 
Researchers develop a fabrication method to increase the efficacy and longevity of membrane separation technology. The team created a nanofibrous membrane with electrospinning, in which a liquid polymer droplet is electrified and stretched to make fibers, and increased the roughness of the membrane surface by loading it with silver nanoparticles. In water, this rough surface promotes a stable layer of water, which acts as a barrier to prevent oil droplets from entering the membrane. The technology is greater than 99% effective at separating a petroleum ether-in-water emulsion.
Published Global research reveals countries where record-breaking heatwaves are likely to cause most harm
(via sciencedaily.com)
Original source 
A new study has highlighted under-prepared regions across the world most at risk of the devastating effects of scorching temperatures.
Published Poor air quality linked to cognitive problems in babies
(via sciencedaily.com)
Original source 
New research shows that poor air quality could be causing cognitive problems in babies and toddlers. A new study reveals an association between poor air quality in India and impaired cognition in infants under two. Without action, the negative impact on children's long-term brain development could have consequences for life.
