Published Precipitation helped drive distribution of Alaska dinosaurs
(via sciencedaily.com) Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research. The finding discusses the distribution of hadrosaurids and ceratopsids -- the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago.
Published Lignin-based jet fuel packs more power for less pollution
(via sciencedaily.com) An experimental plant-based jet fuel could increase engine performance and efficiency, while dispensing with aromatics, the pollution-causing compounds added to conventional fuels, according to new research.
Published Cheaper hydrogen fuel cell could mean better green energy options
(via sciencedaily.com) Researchers have developed a hydrogen fuel cell that uses iron instead of rare and costly platinum, enabling greater use of the technology.
Published Extract from a common kitchen spice could be key to greener, more efficient fuel cells
(via sciencedaily.com) Researchers have discovered a novel way to combine curcumin -- the substance in turmeric -- and gold nanoparticles to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.
Published What is causing the rise in black lung disease?
(via sciencedaily.com) Silica exposure is a driving force behind rising rates of coal workers' pneumoconiosis, according to a new study that compared the pathology and mineralogy of the disease across generations. The study offers scientific evidence explaining why progressive massive fibrosis, the most severe form of black lung disease, is occurring more frequently and among younger coal workers in West Virginia, Virginia and Kentucky.
Published Injured dinosaur left behind unusual footprints
(via sciencedaily.com) A set of dinosaur footprints in Spain has unusual features because the dinosaur that made the tracks had an injured foot, according to a new study.
Published T. rex's short arms may have lowered risk of bites during feeding frenzies
(via sciencedaily.com) Extinct for 66 million years, T. rex still inspires speculation about its anatomy, behavior and fierce physique. One conundrum: its peculiarly short forelimbs, which have relatively limited mobility. While scientists have suggested explanations, a paleontologist puts the proposals to the test and finds them wanting. He hypothesizes that the arms reduced in size to limit damage, possibly fatal, when a pack of T. rexes descended on a carcass with their bone-crunching teeth.
Published Mammals put brawn before brains to survive post-dinosaur world
(via sciencedaily.com) Prehistoric mammals bulked up, rather than develop bigger brains, to boost their survival chances once dinosaurs had become extinct, research suggests.
Published Scavenger nanoparticles could make fuel cell-powered vehicles a reality
(via sciencedaily.com) Engineers have developed a material that could give fuel cell systems a competitive edge over the battery systems that currently power most electric vehicles.
Published New method purifies hydrogen from heavy carbon monoxide mixtures
(via sciencedaily.com) Refining metals, manufacturing fertilizers and powering fuel cells for heavy vehicles are all processes that require purified hydrogen. But purifying, or separating, that hydrogen from a mix of other gases can be difficult, with several steps. Chemical engineers have now demonstrated that the process can be simplified using a pump outfitted with newly developed membrane materials.
Published Fuel from waste wood
(via sciencedaily.com) According to the latest assessment report from the Intergovernmental Panel on Climate Change, a considerable reduction in CO2 emissions is required to limit the consequences of climate change. Producing fuel from renewable sources such as waste wood and straw or renewable electricity would be one way to reduce carbon emissions from the area of transportation.
Published Carbon-coated nickel enables fuel cell free of precious metals
(via sciencedaily.com) A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, researchers have found.
Published Dense bones allowed Spinosaurus to hunt underwater
(via sciencedaily.com) Spinosaurus is the largest predatory dinosaur known -- over two metres longer than the longest Tyrannosaurus rex -- but the way it hunted has been a subject of debate for decades. In a new paper, palaeontologists have taken a different approach to decipher the lifestyle of long-extinct creatures: examining the density of their bones.
Published Wind, solar could replace coal power in Texas
(via sciencedaily.com) A fraction of the wind and solar projects already proposed in Texas could eliminate the state's remaining coal power plants and their emissions, according to engineers.
Published Soil erosion and wildfire another nail in coffin for Triassic era
(via sciencedaily.com) New research has revealed that soil erosion and wildfires contributed to a mass extinction event 201 million years ago that ended the Triassic era and paved the way for the rise of dinosaurs in the Jurassic period.
Published Could we make cars out of petroleum residue?
(via sciencedaily.com) Researchers have developed a way to make lightweight fibers, for possible use in the bodies of cars, out of an ultracheap feedstock: the waste material from the refining of petroleum.
Published Newly identified softshell turtle lived alongside T. rex and Triceratops
(via sciencedaily.com) Scientists describe the find of a new softshell turtle from the end of the Cretaceous Period.
Published Greater greenhouse gas reductions for pickup truck electrification than for other light-duty vehicles
(via sciencedaily.com) Major automotive manufacturers are ramping up production of electric trucks as a key strategy to reduce the greenhouse gas emissions of their vehicles.
Published New species of stegosaur is oldest discovered in Asia, and possibly the world
(via sciencedaily.com) Relatively small, but fearsome-looking stegosaur measured about 2.8 meters (9 feet) from nose to tail -- but scientists can't tell whether the remains are those of an adult or juvenile.
Published Physics race pits Usain Bolt against Jurassic Park dinosaur
(via sciencedaily.com) A physics professor has developed an innovative activity that poses the question: Is Usain Bolt faster than a 900-pound dinosaur?
