Published Ant mounds are more important for biodiversity than previously thought
(via sciencedaily.com) Original source The ant mounds on the heath, in the forest and in your garden are oases for life. The heat and nutrients from ant mounds make them the perfect home for unique plant and animal species, according to new research.
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 How spheres become worms
(via sciencedaily.com) Original source A previously unknown form of hydrogel formation has been elucidated: chemists found unusual interactions between polymers.
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 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 Nifty nanoparticles help 'peel back the curtain' into the world of super small things
(via sciencedaily.com) Original source Physicists are using nanoparticles to develop new sources of light that will allow us to 'peel back the curtain' into the world of extremely small objects -- thousands of times smaller than a human hair -- with major gains for medical and other technologies.
Published A simple paper test could offer early cancer diagnosis
(via sciencedaily.com) Original source Engineers designed a nanoparticle sensor that could enable early diagnosis of cancer with a simple urine test. The sensors, which can detect many cancerous proteins, could also be used to distinguish the type of a tumor or how it is responding to treatment.
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 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 'BeerBots' could speed up the brewing process
(via sciencedaily.com) Original source Craft brewers are continuously upping the ante and coming up with innovative ways to make or flavor their newest beers. Now, researchers are adding a new twist of their own, speeding up the brewing process with beer-making mini-robots or 'BeerBots.' The team shows that these self-propelled, magnetic packages of yeast can make the fermentation phase go faster and cut out the need to filter the beverage.
Published Massive iceberg discharges during the last ice age had no impact on nearby Greenland, raising new questions about climate dynamics
(via sciencedaily.com) Original source New findings suggest that Heinrich Events had no discernible impact on temperatures in Greenland, which could have repercussions for scientists' understanding of past climate dynamics.
Published New programmable smart fabric responds to temperature and electricity
(via sciencedaily.com) Original source A new smart material is activated by both heat and electricity, making it the first ever to respond to two different stimuli.
Published Algae in Swedish lakes provide insights to how complex life on Earth developed
(via sciencedaily.com) Original source By studying green algae in Swedish lakes, a research team has succeeded in identifying which environmental conditions promote multicellularity. The results give us new clues to the amazing paths of evolution.
Published Group cyclists urged to spread out as it can affect exposure to vehicle emissions: Study
(via sciencedaily.com) Original source The notion that in a group of cyclists, the person in front of the group is always the most exposed to harmful vehicle pollutants has now been debunked.
Published Cryo-imaging lifts the lid on fuel cell catalyst layers
(via sciencedaily.com) Original source Thanks to a novel combination of cryogenic transmission electron tomography and deep learning, EPFL researchers have provided a first look at the nanostructure of platinum catalyst layers, revealing how they could be optimized for fuel cell efficiency.
Published Nanowire networks learn and remember like a human brain
(via sciencedaily.com) Original source Scientists have demonstrated nanowire networks can exhibit both short- and long-term memory like the human brain.
Published Greener batteries
(via sciencedaily.com) Original source Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural 'green' materials. A team has now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled.
