Published Tiny biobattery with 100-year shelf life runs on bacteria
(via sciencedaily.com) Original source A tiny biobattery that could still work after 100 years has been developed.
Published The diversity of present tree species is shaped by climate change in the last 21,000 years
(via sciencedaily.com) Original source A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.
Published Nullarbor rocks reveal Australia's transformation from lush to dust
(via sciencedaily.com) Original source Researchers have discovered how long ago the Australian Nullarbor plain dried out, with a new approach shedding light on how ancient climate change altered some of the driest regions of our planet.
Published Professor unearths the ancient fossil plant history of Burnaby Mountain
(via sciencedaily.com) Original source New research led by a paleobotanist provides clues about what plants existed in the Burnaby Mountain area (British Columbia, Canada) 40 million years ago during the late Eocene, when the climate was much warmer than it is today.
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 Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions
(via sciencedaily.com) Original source Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Solid-state lithium-sulfur batteries: Neutrons unveil sluggish charge transport
(via sciencedaily.com) Original source Solid-state Lithium-Sulfur batteries offer the potential for much higher energy densities and increased safety, compared to conventional lithium-ion batteries. However, the performance of solid-state batteries is currently lacking, with slow charging and discharging being one of the primary causes. Now, a new study shows that sluggish lithium ion transport within a composite cathode is the cause of this slow charging and discharging.
Published Researchers correlate Arctic warming to extreme winter weather in midlatitude and its future
(via sciencedaily.com) Original source A warmer Arctic has been linked to extreme winter weather in the midlatitude regions. But, it is not clear how global warming affects this link. In a new study, researchers show, using weather data and climate models, that while the 'Warm Arctic-Cold Continent' pattern will continue as the climate continues to warm, Arctic warming will become a less reliable predictor of extreme winter weather in the future.
Published Ice sheets can collapse faster than previously thought possible
(via sciencedaily.com) Original source Ice sheets can retreat up to 600 meters a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured. An international team of researchers used high-resolution imagery of the seafloor to reveal just how quickly a former ice sheet that extended from Norway retreated at the end of the last Ice Age, about 20,000 years ago.
Published The unexpected contribution of medieval monks to volcanology
(via sciencedaily.com) Original source By observing the night sky, medieval monks unwittingly recorded some of history's largest volcanic eruptions. An international team of researchers drew on readings of 12th and 13th century European and Middle Eastern chronicles, along with ice core and tree ring data, to accurately date some of the biggest volcanic eruptions the world has ever seen. Their results uncover new information about one of the most volcanically active periods in Earth's history, which some think helped to trigger the Little Ice Age, a long interval of cooling that saw the advance of European glaciers.
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 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 Deep ocean currents around Antarctica headed for collapse, study finds
(via sciencedaily.com) Antarctic circulation could slow by more than 40 per cent over the next three decades, with significant implications for the oceans and the climate.
Published A reconstruction of prehistoric temperatures for some of the oldest archaeological sites in North America
(via sciencedaily.com) Scientists often look to the past for clues about how Earth's landscapes might shift under a changing climate, and for insight into the migrations of human communities through time. A new study offers both by providing, for the first time, a reconstruction of prehistoric temperatures for some of the first known North American settlements.
Published Revolutionary battery technology to boost EV range 10-fold or more
(via sciencedaily.com) A team develops layering-charged, polymer-based stable high-capacity anode material.
Published The Greenland Ice Sheet is close to a melting point of no return
(via sciencedaily.com) A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.
Published Sea ice will soon disappear from the Arctic during the summer months -- and it has happened before
(via sciencedaily.com) In a new study, an international team of researchers warn that the Arctic Sea ice may soon be a thing of the past in the summer months. This may have consequences for both the climate and ecosystems. Ten thousand years ago, the ice melted at temperatures similar to those we have today.
Published New invention: The oxygen-ion battery
(via sciencedaily.com) An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.
Published 3000+ billion tons of ice lost from Antarctic Ice Sheet over 25 years
(via sciencedaily.com) Original source Scientists have calculated that the fastest changing Antarctic region?-?the Amundsen Sea Embayment?-?has lost more than 3,000 billion tonnes of ice over a 25-year?period.??
Published Batteries: Passivation layer mystery solved
(via sciencedaily.com) In our daily lives, lithium-ion batteries have become indispensable. They function only because of a passivation layer that forms during their initial cycle. As researchers found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution. Their findings allow the optimization of the performance and lifetime of future batteries.
