Published Mushrooms and their post-rain, electrical conversations
(via sciencedaily.com) Original source Certain types of fungi can communicate with each other via electrical signals. But much remains unknown about how and when they do so. A group of researchers recently headed to the forest to measure the electrical signals of Laccaria bicolor mushrooms, finding that their electrical signals increased following rainfall.
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 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 Brain circuits for locomotion evolved long before appendages and skeletons
(via sciencedaily.com) Original source Scientists found parallels between the neural circuitry that guides locomotion in sea slugs and in more complex animals like mammals.
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 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 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 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 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.
Published Whales stop by Gold Coast bay for day spa fix with full body scrubs
(via sciencedaily.com) Original source A new Griffith University study has found that humpback whales will use sandy, shallow bay areas to 'roll' around in sandy substrates to remove dead skin cells on their return journeys south to cooler waters. Using data and footage collected from the tags, whales were observed performing full and side rolls in up to 49m water depth on the sea floor that was lined with fine sand or rubble.
Published Using solar farms to generate fresh desert soil crust
(via sciencedaily.com) Original source Biocrusts play a crucial role in maintaining soil health and ecosystem sustainability, but they are currently under assault. Human activities including agriculture, urbanization, and off-road vehicle use can lead to the degradation of biocrusts, which have long-term consequences for these fragile environments. Climate change is also placing stress on biocrusts, which struggle to adapt to sunlight and searing heat in arid landscapes like the Sonoran Desert.
Published Greenhouse gas release from permafrost is influenced by mineral binding processes
(via sciencedaily.com) Original source New insights into the binding of carbon to mineral particles in permafrost can improve the prediction of greenhouse gas release.
Published Fungal genetics could help develop novel biotechnologies
(via sciencedaily.com) Original source An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in the biotech industry.
