Published Charting a pathway to next-gen biofuels



From soil to sequestration, researchers have modeled what a supply chain for second-generation biofuels might look like in the midwestern United States.
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 Community science volunteers can set scientific world abuzz with new bumble bee sightings



Community science volunteers -- laypeople with an interest in bees and conservation -- significantly contribute to the scientific knowledge of native bumble bees across Canada and the United States. It's buzz worthy confirmation that community science programs can play an important role in monitoring the changing distributions of bumble bees and more.
Published Cement recycling method could help solve one of the world's biggest climate challenges



Researchers have developed a method to produce very low emission concrete at scale -- an innovation that could be transformative in the transition to net zero. The method, which the researchers say is 'an absolute miracle', uses the electrically-powered arc furnaces used for steel recycling to simultaneously recycle cement, the carbon-hungry component of concrete.
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 Streamlined microcomb design provides control with the flip of a switch



Researchers describe new microcomb lasers they have developed that overcome previous limitations and feature a simple design that could open the door to a broad range of uses.
Published Recycling carbon dioxide into household chemicals



Scientists report a family of tin-based catalysts that efficiently converts CO2 into ethanol, acetic acid and formic acid. These liquid hydrocarbons are among the most produced chemicals in the U.S and are found in many commercial products.
Published Legacy of Indigenous stewardship of camas dates back more than 3,500 years



A new study found evidence that Indigenous groups in the Pacific Northwest were intentionally harvesting edible camas bulbs at optimal stages of the plant's maturation as far back as 3,500 years ago.
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 Researchers find unique adaptations of fungus associated with bee bread



The past attempts of honey bee researchers to inventory the fungal diversity in honey bee colonies revealed that Aspergillus flavus is frequently found in hives. In a new study, researchers have discovered that this fungus is uniquely adapted to survive in bee colonies.
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 Powering wearable devices with high-performing carbon nanotube yarns



Carbon nanotube (CNT) yarns are promising for flexible and fabric-type wearable materials that can convert waste heat into thermoelectricity. To improve the thermoelectric properties of CNT yarns, researchers dispersed CNT filaments in a highly viscous glycerol, enabling the production of CNT yarn with highly aligned bundles together with surfactants that prevent increased thermal conductivity. This innovative approach can significantly improve carbon nanotube-based thermoelectric materials, making it possible to power wearable devices using just body heat.
Published Evolutionary history of extinct duck revealed



The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.
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 Magnetic imprint on deconfined nuclear matter



Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
Published More efficient bioethanol production might be possible using persimmon tannin to help yeast thrive



Researchers have found that persimmon tannin, known for its antioxidant properties, improves the growth of yeast in the presence of ethanol.
Published Wind farms can offset their emissions within two years



After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants.
Published Copper can't be mined fast enough to electrify the US



Copper cannot be mined quickly enough to keep up with current U.S. policy guidelines to transition the country's electricity and vehicle infrastructure to renewable energy, according to a new study.
Published Bees and butterflies on the decline in western and southern North America



Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a new study.
Published Tiger beetles fight off bat attacks with ultrasonic mimicry



When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by showing that tiger beetles use ultrasonic warning signals that mimic those of toxic moths.
