Published Making hydrogen from waste plastic could pay for itself
(via sciencedaily.com) Researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that generates graphene as a by-product, which could help offset production costs.
Published Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs
(via sciencedaily.com) Original source A new study by researchers from the University of Bath (UK) and Universidad Nacional Autónoma de México (Mexico) shows that flowering plants escaped relatively unscathed from the mass extinction that killed the dinosaurs 66 million years ago. Whilst they suffered some species loss, the devastating event helped flowering plants become the dominant type of plant today.
Published Fossil spines reveal deep sea's past
(via sciencedaily.com) Original source Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.
Published Pioneering research sheds surprising new light on evolution of plant kingdom
(via sciencedaily.com) Original source A new study has uncovered intriguing insights into the evolution of plant biology, effectively rewriting the history of how they evolved over the past billion years.
Published Efficient and mild: Recycling of used lithium-ion batteries
(via sciencedaily.com) Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles -- and increasingly also vehicles -- with power. As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.
Published Mutation rates in whales are much higher than previously reported
(via sciencedaily.com) Original source An international team of marine scientists has studied the DNA of family groups from four different whale species to estimate their mutation rates. Using the newly determined rates, the group found that the number of humpback whales in the North Atlantic before whaling was 86 percent lower than earlier studies suggested.
Published Europe's very own dinosaurs -- the enigmatic Late Cretaceous rhabdodontids
(via sciencedaily.com) Original source A new study brings together intriguing details about the little-known Rhabdodontidae dinosaurs of Late Cretaceous Europe. These gregarious herbivores, characterized by robust builds and beaks specialized for tough vegetation, inhabited the European archipelago. Despite being widespread and abundant, they vanished in Western Europe due to environmental changes around 69 million years ago, while surviving longer in Eastern Europe. Their fossil record offers valuable insights into their evolution and lifestyle, although its limited nature still challenges comprehensive understanding.
Published Graphene: Perfection is futile
(via sciencedaily.com) It has long been known that graphene has excellent electronic properties. However, it was unclear until now how stable these properties are. Are they destroyed by disturbances and additional effects, which are unavoidable in practice, or do they remain intact? Scientists have now succeeded in developing a comprehensive computer model of realistic graphene structures. It turned out that the desired effects are very stable. Even graphene pieces that are not quite perfect can be used well for technological applications.
Published Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution
(via sciencedaily.com) Original source Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans.
Published Golden rules for building atomic blocks
(via sciencedaily.com) Physicists have developed a technique to precisely control the alignment of supermoiré lattices by using a set of golden rules, paving the way for the advancement of next generation moiré quantum matter.
Published Wastewater pipe dig reveals 'fossil treasure trove'
(via sciencedaily.com) Original source A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.
Published New quantum device generates single photons and encodes information
(via sciencedaily.com) A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A team stacked two different, atomically thin materials to realize this chiral quantum light source.
Published New study finds ways to suppress lithium plating in automotive batteries for faster charging electric vehicles
(via sciencedaily.com) A new study has found a way to prevent lithium plating in electric vehicle batteries, which could lead to faster charging times.
Published Newly discovered 'primitive cousins of T rex' shed light on the end of the age of dinosaurs in Africa
(via sciencedaily.com) Original source Researchers have discovered the fossils of two new abelisaurs in Morocco, showing the diversity of dinosaurs in this region at the end of the Cretaceous period.
Published Graphene discovery could help generate hydrogen cheaply and sustainably
(via sciencedaily.com) Researchers have finally solved the long-standing puzzle of why graphene is so much more permeable to protons than expected by theory.
Published Scientists zero in on timing, causes of ice age mammal extinctions in southern California
(via sciencedaily.com) Original source Radiocarbon dating on bones in the La Brea Tar Pits lead archaeologists to warn that history may be repeating itself.
Published The modern sea spider had started to diversify by the Jurassic, study finds
(via sciencedaily.com) Original source An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind.
Published Carbon-based quantum technology
(via sciencedaily.com) Graphene nanoribbons have outstanding properties that can be precisely controlled. Researchers have succeeded in attaching electrodes to individual atomically precise nanoribbons, paving the way for precise characterization of the fascinating ribbons and their possible use in quantum technology.
Published Scientists explore dinosaur 'Coliseum' in Denali National Park
(via sciencedaily.com) Original source Scientists have discovered and documented the largest known single dinosaur track site in Alaska. The site, located in Denali National Park and Preserve, has been dubbed 'The Coliseum' by researchers.
Published Key role of ice age cycles in early human interbreeding
(via sciencedaily.com) Original source Recent paleogenomic research revealed that interbreeding was common among early human species. However, little was known about when, where, and how often this hominin interbreeding took place. Using paleoanthropological evidence, genetic data, and supercomputer simulations of past climate, a team of international researchers has found that interglacial climates and corresponding shifts in vegetation created common habitats for Neanderthals and Denisovans, increasing their chances for interbreeding and gene flow in parts of Europe and central Asia.
