Published Engineers devise technology to prevent fouling in photobioreactors for CO2 capture
(via sciencedaily.com) Original source A new, inexpensive technology can limit the buildup of algae on the walls of photobioreactors that can help convert carbon dioxide into useful products. Reducing this fouling avoids costly cleanouts and allows more photosynthesis to happen within tanks.
Published Timing of snowshoe hare winter color swap may leave them exposed in changing climate, study finds
(via sciencedaily.com) Original source A new study, which used 44 years of data, shows that as the globe has warmed, altering the timing and amount of snow cover, snowshoe hares' winter transformation may be out of sync with the color of the background environment; this may actually put them at a greater disadvantage.
Published Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists
(via sciencedaily.com) Original source Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.
Published Electrification push will have enormous impacts on critical metals supply chain
(via sciencedaily.com) Original source The demand for battery-grade lithium, nickel, cobalt, manganese and platinum will climb steeply as vehicle electrification speeds up and nations work to reduce greenhouse gas emissions through mid-century. This surge in demand will also create a variety of economic and supply-chain problems, according to new research.
Published Photonic filter separates signals from noise to support future 6G wireless communication
(via sciencedaily.com) Original source Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The device is expected to help next-generation wireless communication technologies efficiently convey data in an environment that is becoming crowded with signals.
Published Researchers discover new circuit element
(via sciencedaily.com) Original source Researchers have identified a new circuit element known as a meminductor.
Published Cities will need more resilient electricity networks to cope with extreme weather
(via sciencedaily.com) Original source Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.
Published Scientists advocate for integration of biogeography and behavioral ecology to rapidly respond to biodiversity loss
(via sciencedaily.com) Original source An interdisciplinary team of researchers is advocating for convergent research that integrates the fields of biogeography and behavioral ecology to more rapidly respond to challenges associated with climate change and biodiversity loss.
Published Shutting down nuclear power could increase air pollution
(via sciencedaily.com) Original source A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.
Published In Florida study, nonnative leaf-litter ants are replacing native ants
(via sciencedaily.com) Original source A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.
Published Long-forgotten equation provides new tool for converting carbon dioxide
(via sciencedaily.com) Original source To manage atmospheric carbon dioxide and convert the gas into a useful product, scientists have dusted off an archaic -- now 120 years old -- electrochemical equation.
Published Shedding light on mechanisms of electrochemical energy storage
(via sciencedaily.com) Original source Researchers have developed a new technique that can quickly identify the exact electrochemical mechanisms taking place in batteries and supercapacitors of various compositions -- a breakthrough that could speed the design of higher performing energy storage devices.
Published Discovery of ferroelectricity in an elementary substance
(via sciencedaily.com) Original source Researchers have discovered a new single-element ferroelectric material that alters the current understanding of conventional ferroelectric materials and has future applications in data storage devices.
Published Levies on Renewable Energy Profits could serve as a barrier to achieving Net Zero Targets in the UK
(via sciencedaily.com) Original source Placing levies on the profits made in the renewable energy industry could hinder the UK's ability to meet its 2050 net zero carbon reduction targets, an expert has said.
Published Coral skeletons influence reef recovery after bleaching
(via sciencedaily.com) Original source Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.
Published New tool shows progress in fighting spread of invasive grass carp in Great Lakes
(via sciencedaily.com) Original source Researchers created a new way to estimate the abundance of invasive 'sleeper' species in freshwater ecosystems and help guide management strategies.
Published Major storage capacity in water-based batteries
(via sciencedaily.com) Original source Chemical engineers have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.
Published Warming Arctic draws marine predators northwards
(via sciencedaily.com) Original source Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
Published Innovative method predicts the effects of climate change on cold-blooded animals
(via sciencedaily.com) In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.
Published Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk
(via sciencedaily.com) Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.
