Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com) Original source Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published Unknown animals were leaving bird-like footprints in Late Triassic Southern Africa
(via sciencedaily.com) Original source Ancient animals were walking around on bird-like feet over 210 million years ago, according to a new study.
Published Artificial intelligence paves way for new medicines
(via sciencedaily.com) Original source Researchers have developed an AI model that can predict where a drug molecule can be chemically altered.
Published Releasing brakes on biocatalysis
(via sciencedaily.com) Original source Enzymes from microorganisms can produce hydrogen (H2) under certain conditions, which makes them potential biocatalysts for biobased H2 technologies. In order to make this hydrogen production efficient, researchers are trying to identify and eliminate possible limiting factors. These include formaldehyde, which occurs naturally as a metabolic product in cells and inhibits the particularly efficient [FeFe] hydrogenase.
Published Greener solution powers new method for lithium-ion battery recycling
(via sciencedaily.com) Original source Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. Researchers have improved on approaches that dissolve the battery in a liquid solution in order to reduce the amount of hazardous chemicals used in the process. This simple, efficient and environmentally-friendly solution overcomes the main obstacles presented by previous approaches.
Published How shifting climates may have shaped early elephants' trunks
(via sciencedaily.com) Original source Researchers have provided new insights into how ancestral elephants developed their dextrous trunks. A study of the evolution of longirostrine gomphotheres, an ancestor of the modern day elephant, suggests moving into open-land grazing helped develop their coiling and grasping trunks.
Published Chemists use oxygen, copper 'scissors' to make cheaper drug treatments possible
(via sciencedaily.com) Original source Researchers have devised a way to produce chemicals used in medicine and agriculture for a fraction of the usual cost. Using oxygen as a reagent and copper as a catalyst to break organic molecules' carbon-carbon bonds and convert them into amines, which are widely used in pharmaceuticals. Traditional metal catalysis uses expensive metals such as platinum, silver, gold and palladium, but the researchers used oxygen and copper -- an abundant base metal.
Published Hybrid transistors set stage for integration of biology and microelectronics
(via sciencedaily.com) Original source Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
Published This sea worm's posterior body part swims away, and now scientists know how
(via sciencedaily.com) Original source A research team shows how the expression of developmental genes in the Japanese green syllid worms, Megasyllis nipponica, helps form their swimming reproductive unit called stolon.
Published Sophisticated swarming: Bacteria support each other across generations
(via sciencedaily.com) Original source When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and time.
Published New method for determining the water content of water-soluble compounds
(via sciencedaily.com) Original source Researchers have developed a new method for the accurate determination of the water content of water-soluble compounds. This plays a significant role in various areas, including determining drug dosages.
Published Trilobites rise from the ashes to reveal ancient map
(via sciencedaily.com) Original source Ten newly discovered species of trilobites, hidden for 490 million years in a little-studied part of Thailand, could be the missing pieces in an intricate puzzle of ancient world geography.
Published Effect of aerosol particles on clouds and the climate captured better
(via sciencedaily.com) Original source Global measurements and model calculations show that the complex relationship between the chemistry and climate impact of aerosol particles can be successfully captured by a simple formula.
Published Unearthing how a carnivorous fungus traps and digests worms
(via sciencedaily.com) Original source A new analysis sheds light on the molecular processes involved when a carnivorous species of fungus known as Arthrobotrys oligospora senses, traps and consumes a worm.
Published Innovative aquaculture system turns waste wood into nutritious seafood
(via sciencedaily.com) Original source Innovative aquaculture system turns waste wood into nutritious seafood. Researchers hoping to rebrand a marine pest as a nutritious food have developed the world's first system of farming shipworms, which they have renamed 'Naked Clams'.
Published Putting an end to plastic separation anxiety
(via sciencedaily.com) Original source Bio-based plastics often end up in recycling streams because they look and feel like conventional plastic, but the contamination of these compostable products makes it much harder to generate functional material out of recycled plastic. Scientists have now developed a biology-driven process to convert these mixtures into a new biodegradable material that can be used to make fresh products. The scientists believe the process could also enable a new field of biomanufacturing wherein valuable chemicals and even medicines are made from microbes feeding off of plastic waste.
Published Shedding light on unique conduction mechanisms in a new type of perovskite oxide
(via sciencedaily.com) Original source The remarkable proton and oxide-ion (dual-ion) conductivities of hexagonal perovskite-related oxide Ba7Nb3.8Mo1.2O20.1 are promising for next-generation electrochemical devices. The unique ion-transport mechanisms they unveiled will hopefully pave the way for better dual-ion conductors, which could play an essential role in tomorrow's clean energy technologies.
Published Like the phoenix, Australia's giant birds of prey rise again from limestone caves
(via sciencedaily.com) Original source Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again. Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.
Published Much more than waste: Tiny vesicles exchange genetic information between cells in the sea
(via sciencedaily.com) Original source Researchers take a look at data that has so far been mostly discarded as contamination, revealing the previously underestimated role of extracellular vesicles (EVs). These are important for the exchange of genetic information between cells and thus for the microbial community in the sea.
Published Pushing the boundaries of eco-friendly chemical production
(via sciencedaily.com) Original source A team of pioneering researchers has made a significant leap forward in the complex world of molecular chemistry. Their focus? Azaarenes, unique molecular puzzle pieces crucial to many everyday products, from eco-friendly agrochemicals to essential medicines. The team developed an innovative way to modify these molecules using light-powered enzymes -- a groundbreaking discovery that holds promise for new industrially relevant chemical reactions and sustainable energy solutions.
