Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery


A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
Published Prehistoric fish fills 100 million year gap in evolution of the skull



X-rays of an ancient jawless fish shows earliest-known example of internal cartilage skull, unlike that of any other known vertebrate.
Published Tall buildings could be built quicker if damping models were correct, study finds


Multi-story buildings are assembled over-cautiously to withstand wind strengths, researchers have found.
Published Cheap and efficient catalyst could boost renewable energy storage


Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published How wind turbines react to turbulence


The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.
Published RNA for the first time recovered from an extinct species



A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses.
Published Predictive model could improve hydrogen station availability


Consumer confidence in driving hydrogen-fueled vehicles could be improved by having station operators adopt a predictive model that helps them anticipate maintenance needs, according to researchers.
Published Step change in upconversion the key to clean water, green energy and futuristic medicine


Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
Published Making hydrogen from waste plastic could pay for itself


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



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 New ionic materials boost hydrogen fuel cell efficiency!


A research team has made a groundbreaking advancement in improving the efficiency of hydrogen fuel cells, which are gaining significant attention as eco-friendly next-generation energy sources.
Published St Helena's 'liberated' Africans came from West Central Africa between northern Angola and Gabon



Between 1840 and 1867, thousands of enslaved Africans who had been 'liberated' from slave ships intercepted by the British Royal Navy were taken to the South Atlantic island of St Helena. But little is written in history books or otherwise known about the lives of these individuals. Now, ancient DNA analyses offer the first direct evidence for the origins of St Helena's liberated Africans.
Published Scientists develop new method to recover high-purity silicon from expired solar panels for upcycling into lithium-ion batteries


Scientists have devised an efficient method of recovering high-purity silicon from expired solar panels to produce lithium-ion batteries that could help meet the increasing global demand to power electric vehicles.
Published New battery holds promise for green energy


A chemist envisions a future where every house is powered by renewable energy stored in batteries. He has created a new battery that could have profound implications for the large-scale energy storage needed by wind and solar farms.
Published Researchers develop highly efficient and stable photoelectrode for water splitting using organic semiconductors


A recent study has unveiled a significant breakthrough in photoelectrode development.
Published Pioneering research sheds surprising new light on evolution of plant kingdom



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


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 Striking gold with molecular mystery solution for potential clean energy


Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed themselves. The catalytic reaction usually occurs on the reactive -- and expensive -- metal, but on some catalysts, hydrogen atom-like equivalents literally spill from the metal to the oxide. These hydrogen-on-oxide species are called 'hydrogen spillover.'
Published Energy storage in molecules


Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. A team of researchers has used a quantum computing method to find a particularly efficient molecular structure for this purpose. Their procedure was based on a dataset of more than 400,000 molecules, which they screened to find the optimum molecular structure for solar energy storage materials.
Published Europe's very own dinosaurs -- the enigmatic Late Cretaceous rhabdodontids



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.
