Published Producing novel liquid crystals by stacking antiaromatic units



In a recent study, researchers developed modified norcorrole molecules whose side chains favored the formation of columnar -stacking structures. Using these compounds, they produced liquid crystals with high electrical conductivity and thermotropic properties. Their findings open up new design avenues for materials useful in electronics, sensing, optics, and biomedicine.
Published Unlocking complex sulfur molecules: Novel approach for synthesis of functionalized benzenethiol equivalents



Organosulfur skeletons are crucial in many fields, including pharmaceuticals and electronics. Synthesizing organosulfur skeletons requires o-bromobenzenethiols. However, conventional methods face challenges due to quick oxidation and formation of highly reactive intermediates. Researchers have now developed a new method for synthesizing o-bromobenzenethiols from aryne intermediates via bromothiolation. This method can pave the way for the synthesis of new organosulfur compounds with applications in diverse fields.
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 Researchers design new metal-free porous framework materials



Researchers have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.
Published Adhesive coatings can prevent scarring around medical implants



Engineers have found a way to eliminate the buildup of scar tissue around implantable devices, by coating them with a hydrogel adhesive. The material binds the device to tissue and prevents the immune system from attacking the device.
Published Promethium bound: Rare earth element's secrets exposed



Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.
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 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes



In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.
Published New polystyrene recycling process could be world's first to be both economical and energy-efficient



Engineers have modeled a new way to recycle polystyrene that could become the first viable way of making the material reusable.
Published Ethylene from CO2: Building-kit catalyst



Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. Nitrogen atoms with a particular electron configuration play a critical role for the catalyst.
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 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 Can coal mines be tapped for rare earth elements?



A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.
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 Seeking stronger steel, systematic look at 120 combinations of alloy elements provides clues



Investigating ways to create high-performance steel, a research team used theoretical calculations on 120 combinations of 12 alloy elements, such as aluminum and titanium, with carbon and nitrogen, while also systematically clarifying the bonding mechanism.
