Published Industrial pollution leaves its mark in Mediterranean corals



For the first time, pollutants from burning fossil fuels have been found embedded in corals, offering scientists a potential new tool to track the history of pollution, finds a new study.
Published New process allows full recovery of starting materials from tough polymer composites



In a win for chemistry, inventors have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer and later recovering all of its starting materials.
Published Researchers unveil method to detect 'forever chemicals' in under 3 minutes



PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.
Published Technique could improve the sensitivity of quantum sensing devices



A new technique can control a larger number of microscopic defects in a diamond. These defects can be used as qubits for quantum sensing applications, and being able to control a greater number of qubits would improve the sensitivity of such devices.
Published Foul fumes pose pollinator problems



Scientists have discovered that nighttime air pollution -- coming primarily form car exhaust and power plant emissions -- is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.
Published Physicists capture the first sounds of heat 'sloshing' in a superfluid



For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of heat flow in superconductors and neutron stars.
Published Combining materials may support unique superconductivity for quantum computing



A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum computing.
Published Greenhouse gas repurposed



Cutting-edge research converted waste carbon dioxide into a potential precursor for chemicals and carbon-free fuel.
Published Scientists develop artificial 'worm gut' to break down plastics



A team of scientists has developed an artificial 'worm gut' to break down plastics, offering hope for a nature-inspired method to tackle the global plastic pollution problem.
Published What turned Earth into a giant snowball 700 million years ago? Scientists now have an answer



Inspired during field work in South Australia's Flinders Ranges, geoscientists have proposed that all-time low volcanic carbon dioxide emissions triggered a 57-million-year-long global 'Sturtian' ice age.
Published Green doesn't always mean clean: Cleaning products urgently need better regulation, researchers warn



Researchers say there needs to be better regulation and more guidance for consumers about how safe cleaning products really are.
Published New study sheds new light on forests' role in climate and water cycle



Forests, which cover a third of Earth's land surface, are pivotal in carbon storage and the water cycle, though the full scope of their impact remains to be fully understood. In a new study, researchers provide new insights into the complex role forests play in the climate system and water cycle.
Published Inexpensive, carbon-neutral biofuels are finally possible



When it comes to making fuel from plants, the first step has always been the hardest -- breaking down the plant matter. A new study finds that introducing a simple, renewable chemical to the pretreatment step can finally make next-generation biofuel production both cost-effective and carbon neutral.
Published 3D printed nanocellulose upscaled for green architectural applications



For the first time, a hydrogel material made of nanocellulose and algae has been tested as an alternative, greener architectural material. The study shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods.
Published MXene-coated devices can guide microwaves in space and lighten the payload



One of the most important components of satellites that enable telecommunication is the waveguide, which is a metal tube for guiding radio waves. It is also one of the heaviest payloads satellites carry into orbit. As with all space technology, reducing weight means reducing the amount of expensive and greenhouse gas-producing fuel it takes to launch a rocket, or increasing the number of devices carried by the same rocket to space. Researchers are trying to lighten the load by creating and testing a waveguide made from 3D-printed polymers coated with a conductive nanomaterial called MXene.
Published Researchers reveal elusive bottleneck holding back global effort to convert carbon dioxide waste into usable products



Think of it as recycling on the nanoscale: a tantalizing electrochemical process that can harvest carbon before it becomes air pollution and restructure it into the components of everyday products. The drive to capture airborne carbon dioxide from industrial waste and make it into fuel and plastics is gaining momentum after a team of researchers uncovered precisely how the process works and where it bogs down.
Published Structural isomerization of individual molecules using a scanning tunneling microscope probe



An international research team has succeeded in controlling the chirality of individual molecules through structural isomerization. The team also succeeded in synthesizing highly reactive diradicals with two unpaired electrons. These achievements were made using a scanning tunneling microscope probe at low temperatures.
Published How plants obtain nitrogen by supplying iron to symbiotic bacteria



Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors regulate nitrogen homeostasis by maintaining a balance between nitrogen and iron concentrations in plants without rhizobial symbiosis.
Published Unveiling the generation principles of charged particles 'trion' in 2D semiconductor



Researchers pioneer dynamic manipulation and the generation principles of trion at the nanoscale using tip-enhanced cavity-spectroscopy.
Published Ammonia attracts the shipping industry, but researchers warn of its risks



Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia -- as well as emissions of laughing gas, which is a very potent greenhouse gas.
