Published Researchers identify unique phenomenon in Kagome metal



A new study focuses on how a particular Kagome metal interacts with light to generate what are known as plasmon polaritons -- nanoscale-level linked waves of electrons and electromagnetic fields in a material, typically caused by light or other electromagnetic waves.
Published Scientists using new sound tech to save animals from extinction



Scientists are using new technology to help endangered animals by listening to their sounds.
Published Organic nanozymes have broad applications from food and agriculture to biomedicine



Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.
Published Plant-inspired polymers for water purification



Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.
Published Thousands of birds and fish threatened by mining for clean energy transition, study finds



Our increasing demand for metals and minerals is putting over four thousand vertebrate species at risk, with the raw materials needed for clean energy infrastructure often located in global biodiversity hotspots, a study has found.
Published Pioneering measurement of the acidity of ionic liquids using Raman spectroscopy



A study has made it possible to estimate experimentally the energy required to transfer protons from water to ionic liquids.
Published The ancestor of all modern birds probably had iridescent feathers



Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Published 'Miracle' filter turns store-bought LEDs into spintronic devices



Scientists transformed existing optoelectronic devices into ones that can control electron spin at room temperature, without a ferromagnet or magnetic field. Researchers replaced the electrodes of store-bought LEDs with a patented spin filter made from hybrid organic-inorganic halide perovskite.
Published New Zealand's flightless birds are retreating to moa refuges



Researchers have found New Zealand's endangered flightless birds are seeking refuge in the locations where six species of moa last lived before going extinct.
Published Ancient marine animal had inventive past despite being represented by few species



Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine



Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Better way to produce green hydrogen



Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
Published Tackling industrial emissions begins at the chemical reaction



Researchers are proposing a new way to curb industrial emissions, by tapping into the 'atomic intelligence' of liquid metals to deliver greener and more sustainable chemical reactions.
Published Researchers discover faster, more energy-efficient way to manufacture an industrially important chemical



The reactivity of zirconium on silicon nitride enhances the conversion of propane into propylene, a key commodity chemical needed to make polypropylene. This finding hints at the reactivity researchers might achieve with other nontraditional catalysts.
Published Researchers develop innovative battery recycling method



A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published Komodo dragons have iron-coated teeth to rip apart their prey



Scientists have discovered that the serrated edges of Komodo dragons' teeth are tipped with iron. The study gives new insight into how Komodo dragons keep their teeth razor-sharp and may provide clues to how dinosaurs like Tyrannosaurus rex killed and ate their prey.
Published Scientists assess how large dinosaurs could really get



A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.
Published A new way to make element 116 opens the door to heavier atoms



Researchers have successfully made super-heavy element 116 using a beam of titanium-50. That milestone sets the team up to attempt making the heaviest element yet: 120.
Published Researchers develop more environmentally friendly and cost-effective method for soil remediation



Chemists have developed a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment.
Published A window of opportunity for climate change and biodiversity



World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle climate change and biodiversity loss, say scientists. Without this, work on tackling either crisis could inadvertently harm progress on the other.
