Published Renewable grid: Recovering electricity from heat storage hits 44% efficiency



Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to new research.
Published Iron could be key to less expensive, greener lithium-ion batteries, research finds



Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Published New milestone for lithium metal batteries



Scientists develop a porous structures for lithium metal batteries.
Published The global clean water crisis looms large



Water scarcity will intensify with climate and socioeconomic change, disproportionately impacting populations located in the Global South.
Published Rising temperatures will significantly reduce streamflow in the upper Colorado river basin as groundwater levels fall



The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.
Published Future climate impacts put whale diet at risk



A new study predicts future climate change impacts could disrupt the krill-heavy diet that humpback whales in the southern hemisphere consume.
Published Beach erosion will make Southern California coastal living five times more expensive by 2050, study predicts



Southern California's iconic sandy coastlines are vanishing at an alarming rate, and it's a warning sign for coastal communities worldwide, new research suggests.
Published Smoke covered 70% of California during biggest wildfire years



As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published Conservation of nature's strongholds needed to halt biodiversity loss



To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.
Published Alaska's rusting waters: Pristine rivers and streams turning orange



Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.
Published Batteries: Modeling tomorrow's materials today



Which factors determine how quickly a battery can be charged? Microstructural models have helped researchers discover and investigate new electrode materials. When sodium-nickel-manganese oxide is used as cathode material in sodium-ion batteries, simulations reveal modifications of the crystal structure during charging. These modifications lead to an elastic deformation, as a result of which capacity decreases.
Published Regional differences in bird diversity in agroforestry systems



The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.
Published Rabies outbreaks in Costa Rica cattle linked to deforestation



Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study.
Published A rise in sea urchins and related damage to kelp forests impacts Oregon's gray whales and their food



A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.
Published The impacts of climate change on food production



A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Cloudy waters causes African fish to develop bigger eyes



Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
Published Subduction zone splay faults compound hazards of great earthquakes



Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis.
Published Record low Antarctic sea ice 'extremely unlikely' without climate change



Scientists have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without climate change and four times more likely under its effects.
Published How heatwaves are affecting Arctic phytoplankton



The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic. The phytoplankton's behavior primarily depends on the cooling phases after or between heatwaves.
Published Can we revolutionize the chemical industry and create a circular economy? Yes, with the help of catalysts



A new commentary paper puts forth a transformative solution to the unsustainable reliance on fossil resources by the chemical industry: catalysis to leverage sustainable waste resources, ushering the industry from a linear to a circular economy.
