Published Self-powered microbial fuel cell biosensor for monitoring organic freshwater pollution



Biodegradable waste from plant and animal sources released into freshwater ecosystems is a significant environmental concern. Nonetheless, current methods for assessing water quality seem more or less impractical due to their complexity and high costs. In a promising development, a team of researchers has successfully constructed a self-sustaining and buoyant biosensor using inexpensive carbon-based materials for monitoring water quality at the inlets of freshwater lakes and rivers.
Published Two million European households could abandon the electrical grid by 2050



Researchers report that 53% of European freestanding homes could have supplied all their own energy needs in 2020 using only local rooftop solar radiation, and this technical feasibility could increase to 75% in 2050. The study shows that there is no economic advantage for individual households to be fully self-sufficient under current or future conditions, though in some cases the costs are on par with remaining on-grid. The researchers estimate that self-sufficiency will be economically feasible for 5% (two million) of Europe's 41 million freestanding single-family homes in 2050, if households are willing to pay up to 50% more than the cost of remaining fully grid dependent.
Published Buzz around new centralized pollination portal for better global bee data



A powerful new way to fill major gaps in public bee data -- including from Africa, Asia and other under-reported zones -- has been addressed with a centralized tool for consolidating bee pollinator occurrences around the globe.
Published Efficient biohybrid batteries



Formic acid, which can be produced electrochemically from carbon dioxide, is a promising energy carrier. A research team has now developed a fast-charging hybrid battery system that combines the electrochemical generation of formic acid as an energy carrier with a microbial fuel cell. This novel, fast-charging biohybrid battery system can be used to monitor the toxicity of drinking water, just one of many potential future applications.
Published Australasia's hidden pollination crisis could threaten biodiversity and food security



Australasia's hidden pollination crisis, mirroring global threats, could pose a significant risk to regional biodiversity and food security, new research has found.
Published Study uncovers hundred-year lifespans for three freshwater fish species in the Arizona desert



New study finds some of the oldest animals in the world living in a place you wouldn't expect: fishes in the Arizona desert.
Published Two bee species become one as researchers solve identity puzzle



A new study has found that what were thought to be two different species of native Australian bee are in fact one.
Published Wireless device makes magnetism appear in non-magnetic materials



Researchers have succeeded in bringing wireless technology to the fundamental level of magnetic devices. The emergence and control of magnetic properties in cobalt nitride layers (initially non-magnetic) by voltage, without connecting the sample to electrical wiring, represents a paradigm shift that can facilitate the creation of magnetic nanorobots for biomedicine and computing systems where basic information management processes do not require wiring.
Published Increasing risk of invasive species colonization on marine debris



A groundbreaking scientific study conducted along the Southeast coast of India has unearthed a pressing environmental concern -- the increasing risk of invasive species colonization on marine debris. The research delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters.
Published New battery technology could lead to safer, high-energy electric vehicles



Researchers studying how lithium batteries fail have developed a new technology that could enable next-generation electric vehicles (EVs) and other devices that are less prone to battery fires while increasing energy storage.
Published Even treated wood prevents bacterial transmission by hand



According to a new study, surface treatment and moisture affect the antibacterial properties of wood. Based on the findings, treated wood should be increasingly used as surface material.
Published DNA Origami nanoturbine sets new horizon for nanomotors



Researchers introduce a pioneering breakthrough in the world of nanomotors -- the DNA origami nanoturbine. This nanoscale device could represent a paradigm shift, harnessing power from ion gradients or electrical potential across a solid-state nanopore to drive the turbine into mechanical rotations. The core of this pioneering discovery is the design, construction, and driven motion of a 'DNA origami' turbine, which features three chiral blades, all within a minuscule 25-nanometer frame, operating in a solid-state nanopore. By ingeniously designing two chiral turbines, researchers now have the capability to dictate the direction of rotation, clockwise or anticlockwise.
Published Bitcoin mining has 'very worrying' impacts on land and water, not only carbon



As bitcoin and other cryptocurrencies have grown in market share, they've been criticized for their heavy carbon footprint: Cryptocurrency mining is an energy-intensive endeavor. Mining has massive water and land footprints as well, according to a new study that is the first to detail country-by-country environmental impacts of bitcoin mining.
Published Scientists develop new method to create stable, efficient next-gen solar cells



Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing visible light.
Published Tiny spirits roam the corals of Japan -- two new pygmy squids discovered



Named after Japanese folklore, two cephalopod species have been discovered in the coastal waters of the Okinawa Islands.
Published Soil carried on sea freight loaded with dangerous pests and diseases, research finds



While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
Published Unearthing the ecological impacts of cicada emergences on North American forests



New research unveils the cascading effects of periodical cicada emergence events on forest ecosystems ahead of an historic convergence of broods set to emerge spring of 2024.
Published Heat waves harm bird reproduction on agricultural lands



The effects of extreme temperatures on avian reproduction can vary depending on the type of environment that birds call home. A new study found that extreme high temperatures significantly diminish bird reproductive success in agricultural landscapes.
Published Cobalt-free battery for cleaner, greener power



High-capacity and reliable rechargeable batteries are a critical component of many devices and even modes of transport. They play a key role in the shift to a greener world. A wide variety of elements are used in their production, including cobalt, the production of which contributes to some environmental, economic, and social issues. A team now presents a viable alternative to cobalt which in some ways can outperform state-of-the-art battery chemistry. It also survives a large number of recharge cycles, and the underlying theory can be applied to other problems.
