Published Greenhouse gas release from permafrost is influenced by mineral binding processes



New insights into the binding of carbon to mineral particles in permafrost can improve the prediction of greenhouse gas release.
Published Fungal genetics could help develop novel biotechnologies



An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in the biotech industry.
Published Biologists discover bees to be brew masters of the insect world



Scientists have made a remarkable discovery about cellophane bees -- their microbiomes are some of the most fermentative known from the insect world. These bees, which are named for their use of cellophane-like materials to line their subterranean nests, are known for their fascinating behaviors and their important ecological roles as pollinators. Now, researchers have uncovered another aspect of their biology that makes them even more intriguing.
Published Chitin from consuming insects can help both gut microbiota and global health



Increased insect consumption by humans may be better for both gut health and planetary health. Chitin (kai'tin) and healthy fats from insects appear to contribute to healthy gut microbiota and are strong sources of protein and nutrients, according to a recent paper.
Published Recycling lake sediments for crop production: A sustainable solution for closing the phosphorus cycle



A four-year field experiment conducted on the shores of restored Lake Mustijärv in Viljandi, Estonia, has revealed that recycling phosphorus-rich lake sediments back to agriculture could have positive impacts on crop production.
Published Chicken breeding in Japan dates back to fourth century BCE



Conclusive evidence of chicken breeding in the Yayoi period of Japan has been discovered from the Karako-Kagi site.
Published African penguins: Climate refugees from a distant past?



Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.
Published Immediate carbon cuts, common marine heatwave terminology urged



Oceanographers provide a reality check on the limitations of carbon dioxide removal and a warning that marine heatwaves need clear definitions so communities can adapt.
Published Scientists identify 2022 sea urchin killer



A team of researchers has identified a single-celled organism called a ciliate as the cause of a massive die-off event to a marine animal vital to coral reef health.
Published Nature's chefs: Scientists propose food-making as means of understanding species interactions



An interdisciplinary group of researchers is proposing a new way to think of some interactions between species, classifying a variety of plants, animals and fungi as 'nature's chefs.' Specifically, nature's chefs are organisms that provide food -- or the illusion of food -- to other organisms. The concept offers a new perspective on species interactions, which can inform how people think about food across the tree of life as well as disparate research disciplines.
Published Why this bird flu is different: Scientists say new avian influenza requires urgent coordinated response



A new study tracks arrival and spread of highly pathogenic Avian Influenza (H5N1) decimating wild birds, impacting poultry and pushing up egg prices. The team found that the deadly impact on wild birds and a shift from seasonal to year-round infections signal dangerous changes in avian influenza in the U.S.
Published New findings pave the way for stable organic solar cells that may enable cheap and renewable electricity generation



Organic solar cells show great promise for clean energy applications. However, photovoltaic modules made from organic semiconductors do not maintain their efficiency for long enough under sunlight for real world applications. Scientists have now revealed an important reason why organic solar cells rapidly degrade under operation. This new insight will drive the design of more stale materials for organic semiconductor-based photovoltaics, thus enabling cheap and renewable electricity generation.
Published Organic beekeeping rivals conventional methods for bee health, productivity



Honey bee colonies managed using organic methods were as healthy and productive as those managed in conventional systems, while avoiding the use of synthetic pesticides to control pests and pathogens inside the hive, according to entomologists.
Published Stronger paper bags, reused repeatedly then recycled for biofuel could be future



As the world searches for ways to reduce the use of plastics such as single-use plastic bags, a novel study demonstrates a process to make paper bags stronger -- especially when they get wet -- to make them a more viable alternative.
Published X-ray analysis sheds new light on prehistoric predator's last meal



We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.
Published How does a millipede get its legs?



Millipede legs grow in an unexpected way, according to new research. Previously, it was thought that when a millipede molts (sheds its exoskeleton), it grows new segments on the end of its body without legs. Then after the next molt, the previously new segments re-emerge with fully formed legs attached. However, a team has found that new segments actually contain tiny bundles of legs, which appear as transparent protrusions before molting and then become fully formed afterwards. This discovery could help us understand how not only millipedes, but also other arthropods (invertebrates with jointed legs) grow.
Published Using machine learning to find reliable and low-cost solar cells



Hybrid perovskites are organic-inorganic molecules that have received a lot of attention over the past 10 years for their potential use in renewable energy. Some are comparable in efficiency to silicon for making solar cells, but they are cheaper to make and lighter, potentially allowing a wide range of applications, including light-emitting devices. However, they tend to degrade way more readily than silicon when exposed to moisture, oxygen, light, heat, and voltage. Researchers used machine learning and high-throughput experiments to identify perovskites with optimal qualities out of the very large field of possible structures.
Published Chemists propose ultrathin material for doubling solar cell efficiency



Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.
Published SpyLigation uses light to switch on proteins



Scientists can now use light to activate protein functions both inside and outside of living cells. The new method, called light-activated SpyLigation, can turn on proteins that are normally off to allow researchers to study and control them in more detail. This technology has potential uses in tissue engineering, regenerative medicine, and understanding how the body works. The scientists applied their new method to control the glow of a green fluorescent protein derived from Japanese eel muscle.
Published Swimming secrets of prehistoric reptiles unlocked by new study



The diverse swimming techniques of the ancient reptiles that ruled the Mesozoic seas have been revealed.
