Published New material offers more durable, sustainable multi-level non-volatile phase change memory


Researchers scientists have unlocked a new realm of possibilities for non-volatile phase change memory, a type of electronic memory capable of retaining data even without power. Traditionally, researchers have relied on chalcogenides, materials with reversible electrical properties during transitions between crystalline and amorphous states. But an exciting alternative has emerged in the form of layered nickelates, complex oxide materials composed of nickel ions. These nickelates, with their unique layered structure and thermally reversible switching of room-temperature electrical resistivity, offer superior performance and sustainability potential.
Published Balancing biodiversity, climate change, food for a trifecta


Scientists identify ways landowners in rural Brazil can find win-win situations with biodiversity and farming.
Published Electrifying heavy-duty vehicles could reduce environmental inequalities


If the region surrounding Chicago -- North America's largest freight hub -- shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new study. The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.
Published Invasive species are animals, too: Considering a humane approach


Invasive alien species are animals that may pose a threat to biodiversity, but it's time to deal with that threat in a more ethical way.
Published Large herbivores keep invasive plants at bay


Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.
Published Scientists develop an energy-efficient wireless power and information transfer system


Simultaneous wireless information and power transfer (SWIPT)-aided nonorthogonal multiple access (NOMA) system, used for communication in the Industrial Internet of Things (IIoTs), suffers from significant energy loss with transmission distance. Now, researchers have developed an energy-efficient framework by applying SWIPT-NOMA to a distributed antenna system. This technology is expected to pave the way for more efficient and optimized IoT environments.
Published Farms that create habitat key to food security and biodiversity


Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.
Published Better cybersecurity with new material


Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published Flowering for naught: 120 years with nothing to show



Flowering for some plants is a yearly occurrence, for others, it is a once-in-a-lifetime event. A widespread species of bamboo in Japan, Phyllostachys nigra var. henonis, takes this one-time flowering event and pushes it to the extreme: they flower once every 120 years before dying to make way for the next generation. Researchers have realized there might be another issue at hand with this monocarpic species, which is the lack of germination of the seeds from a majority of the flowering specimens. Implications of a once dense field of bamboo, something that serves both as a food source and a source of material for crafts, turning to grassland for several years until the regeneration of bamboo begins to start somehow, can impact the ecology of the area in addition to the country's economy.
Published Coastal fisheries show surprising resilience to marine heat waves


New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.
Published New 'droplet battery' could pave the way for miniature bio-integrated devices


Researchers have developed a miniature battery that could be used to power tiny devices integrated into human tissues. The design uses an ionic gradient across a chain of droplets -- inspired by how electric eels generate electricity. The device was able to regulate the biological activity of human neurons. This could open the way to the development of tiny bio-integrated devices, with a range of applications in biology and medicine.
Published Male crested macaques more likely to respond to offspring screams recruiting support



When infants are involved in agonistic conflicts, male crested macaques (Macaca nigra) are more likely to respond to screams from their own offspring. This is the conclusion of a recent study led by behavioral ecologists. The researchers studied the behavior of crested macaques in the Tangkoko Nature Reserve on Sulawesi, Indonesia, over a 24-month period (2008 to 2010).
Published Direct power generation from methylcyclohexane using solid oxide fuel cells



Methylcyclohexane is very promising as a hydrogen carrier that can safely and efficiently transport and store hydrogen. However, the dehydrogenation process using catalysts has issues due to its durability and large energy loss. Recently, researchers have succeeded in using solid oxide fuel cells to generate electricity directly from methylcyclohexane and recover toluene for reuse. This research is expected to not only reduce energy requirements but also explore new chemical synthesis by fuel cells.
Published Broken by bison, aspen saplings having a tough time in northern Yellowstone


In northern Yellowstone National Park, saplings of quaking aspen, an ecologically important tree in the American West, are being broken by a historically large bison herd, affecting the comeback of aspen from decades of over-browsing by elk.
Published Researcher finds inspiration from spider webs and beetles to harvest fresh water from thin air


A team of researchers is designing novel systems to capture water vapor in the air and turn it into liquid. They have developed sponges or membranes with a large surface area that continually capture moisture from their surrounding environment.
Published New study reveals anti-cancer properties in Kencur ginger



Scientists have verified the anticancer effects of Kencur, a tropical plant of the ginger family, mainly grown in Southeast Asia, in cell and animal experiments. They found that Kencur extract and its main active components significantly inhibit cancer cell growth at the cellular and animal levels. Furthermore, the involvement of TFAM in the mechanism of action was confirmed.
Published Soils forming on the branches of trees are an overlooked forest habitat


A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced.
Published Math enables blending hydrogen in natural gas pipelines


Mathematical modeling can show how to safely blend hydrogen with natural gas for transport in existing pipeline systems. A secure and reliable transition to hydrogen is one of the proposed solutions for the shift to a net-zero-carbon economy.
Published Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses


Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.
Published New study finds ways to suppress lithium plating in automotive batteries for faster charging electric vehicles


A new study has found a way to prevent lithium plating in electric vehicle batteries, which could lead to faster charging times.
