(via sciencedaily.com) Original source New research could lead to major improvements in marine oil spill cleanup processes. The innovative study assessed the impact of the Deepwater Horizon oil spill on microscopic seawater bacteria that perform a significant role in ecosystem functioning.
Published Breakthrough research enhances stability and efficiency of perovskite solar cells
(via sciencedaily.com) Original source A research team has achieved remarkable advancements in the stability and efficiency of perovskite solar cells.
Published Groundbreaking discovery enables cost-effective and eco-friendly green hydrogen production
(via sciencedaily.com) Original source A research team has developed a novel catalyst for the high-efficiency and stable production of high-purity green hydrogen.
Published Food from urban agriculture has carbon footprint 6 times larger than conventional produce, study shows
(via sciencedaily.com) Original source A new study finds that fruits and vegetables grown in urban farms and gardens have a carbon footprint that is, on average, six times greater than conventionally grown produce.
Published Ice age could help predict oceans' response to global warming
(via sciencedaily.com) Original source A new way to measure the ocean oxygen level and its connections with carbon dioxide in the Earth's atmosphere during the last ice age could help explain the role oceans played in past glacial melting cycles and improve predictions of how ocean carbon cycles will respond to global warming.
Published The megalodon was less mega than previously believed
(via sciencedaily.com) Original source A new study shows the Megalodon, a gigantic shark that went extinct 3.6 million years ago, was more slender than earlier studies suggested. This finding changes scientists' understanding of Megalodon behavior, ancient ocean life, and why the sharks went extinct.
Published Wobbling particles in the sky
(via sciencedaily.com) Original source Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size smaller than 1 millimeter with unprecedented accuracy. Their observations gave rise to a model which can help to refine prediction on air pollutants or weather forecasts.
Published Sea otters helped prevent widespread California kelp forest declines over the past century
(via sciencedaily.com) Original source The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.
Published Climate change linked to spread of diarrheal illness
(via sciencedaily.com) Original source Temperature, day length and humidity have been found to be linked to the increased spread of a diarrheal illness a new study reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services.
Published Scientists, farmers and managers work together to avoid the decline of the little bustard, an endangered steppe bird
(via sciencedaily.com) Original source The collaboration between scientists, farmers and managers is crucial to improve the protection of the little bustard, an endangered steppe-land bird in Spain due to human activity. The reduction of natural habitats, the increase in irrigation and the urbanization of the land have led to having less surface areas that guarantee the survival of this vulnerable species.
Published Researchers pump brakes on 'blue acceleration' harming the world ocean
(via sciencedaily.com) Original source Protecting the world ocean against accelerating damage from human activities could be cheaper and take up less space than previously thought, new research has found.
Published Machine learning method speeds up discovery of green energy materials
(via sciencedaily.com) Original source Researchers have developed a framework that uses machine learning to accelerate the search for new proton-conducting materials, that could potentially improve the efficiency of hydrogen fuel cells.
Published Why animals shrink over time explained with new evolution theory
(via sciencedaily.com) Original source The new theoretical research proposes that animal size over time depends on two key ecological factors.
Published Key factors in human-made earthquakes
(via sciencedaily.com) Original source Researchers report that the roughness of pre-existing faults and associated stress heterogeneity in geological reservoirs play a key role for causing human-made earthquakes, so-called runaway events. The study combines novel fluid injection experiments under acoustic monitoring performed in GFZ's geomechanical laboratory with numerical modelling results.
Published Next-generation batteries could go organic, cobalt-free for long-lasting power
(via sciencedaily.com) Original source In the switch to 'greener' energy sources, the demand for rechargeable lithium-ion batteries is surging. However, their cathodes typically contain cobalt -- a metal whose extraction has high environmental and societal costs. Now, researchers in report evaluating an earth-abundant, carbon-based cathode material that could replace cobalt and other scarce and toxic metals without sacrificing lithium-ion battery performance.
Published Translating nuclear waste site data into microbial ecosystem insights
(via sciencedaily.com) Original source A flagship seven-year study that explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater has now been published.
Published Efficiently moving urea out of polluted water is coming to reality
(via sciencedaily.com) Original source Researchers have developed a material to remove urea from water and potentially convert it into hydrogen gas. By building these materials of nickel and cobalt atoms with carefully tailored electronic structures, the group has unlocked the potential to enable these transition metal oxides and hydroxides to selectively oxidize urea in an electrochemical reaction. The team's findings could help use urea in waste streams to efficiently produce hydrogen fuel through the electrolysis process, and could be used to sequester urea from water, maintaining the long-term sustainability of ecological systems, and revolutionizing the water-energy nexus.
Published Cobalt-free batteries could power cars of the future
(via sciencedaily.com) Original source A new battery material could offer a more sustainable way to power electric cars. The lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel.
Published The heat is on: Scientists discover southern Africa's temps will rise past the rhinos' tolerance
(via sciencedaily.com) Original source Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts aimed at protecting rhinos have focused on poaching, but until now, there has been no analysis of the impact that climate change may have on the animals. A research team has recently reported that, though the area will be affected by both higher temperatures and changing precipitation, the rhinos are more sensitive to rising temperatures, which will quickly increase above the animals' acceptable maximum threshold.
Published Rain can spoil a wolf spider's day, too
(via sciencedaily.com) Original source Researchers found that wolf spiders can't signal others or perceive danger from predators as easily on rain-soaked leaves compared to dry ones. Even communicating with would-be mates is harder after it rains.
