Published Fossil discovery in storeroom cupboard shifts origin of modern lizard back 35 million years


A specimen retrieved from a cupboard of the Natural History Museum in London has shown that modern lizards originated in the Late Triassic and not the Middle Jurassic as previously thought.
Published Health benefits of using wind energy instead of fossil fuels


A new study finds that the health benefits associated with wind power could more than quadruple if operators turned down output from the most polluting fossil-fuel-based power plants when energy from wind is available. However, compared to wealthier communities, disadvantaged communities would reap a smaller share of these benefits.
Published Lost medieval chapel sheds light on royal burials at Westminster Abbey, finds new study featuring 15th-century reconstruction


New evidence, helping to form a 15th-century reconstruction of part of Westminster Abbey, demonstrates how a section of the building was once the focus for the royal family's devotion to the cult of a disemboweled saint and likely contained gruesome images of his martyrdom.
Published Fossil overturns more than a century of knowledge about the origin of modern birds


Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds.
Published Mammoth problem with extinction timeline



Paleontologists say environmental DNA is not always helpful in identifying when animals like mammoths went extinct because genetic material found in sediment could have come from animals that died thousands of years earlier.
Published New quantum computing feat is a modern twist on a 150-year-old thought experiment


New research demonstrates a 20x improvement in resetting a quantum bit to its '0' state, using a modern version of the 'Maxwell's demon'.
Published Researchers create method for making net-zero aviation fuel


An interdisciplinary team of researchers has developed a potential breakthrough in green aviation: a recipe for a net-zero fuel for planes that will pull carbon dioxide (CO2) out of the air.
Published DNA sequence enhances understanding origins of jaws


Researchers have discovered and characterized a DNA sequence found in jawed vertebrates, such as sharks and humans, but absent in jawless vertebrates, such as lampreys. This DNA is important for the shaping of the joint surfaces during embryo development.
Published Ancient superpredator got big by front-loading its growth in its youth



Whatcheeria, a six-foot-long salamander-like creature that lived 340 million years ago, was the T. rex of its time: the biggest, baddest predator in its habitat. A new study reveals how they grew to their 'giant' size: instead of growing slow and steady throughout their lives like many modern reptiles and amphibians, they did most of their growing when they were young.
Published 525-million-year-old fossil defies textbook explanation for brain evolution


According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom. Combining detailed anatomical studies of the fossilized nervous system with analyses of gene expression patterns in living descendants, they conclude that a shared blueprint of brain organization has been maintained from the Cambrian until today.
Published Ancient Roman coins reveal long-lost emperor


A gold coin long dismissed as a forgery appears to be authentic and depicts a long-lost Roman emperor named Sponsian, according to a new study.
Published 1,700-year-old spider monkey remains discovered in Teotihuacán, Mexico



The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.
Published Footprints claimed as evidence of ice age humans in North America need better dating, new research shows


The preserved footprints found in New Mexico's Lake Otero Basin would upend scientific understanding of how, and when, humans first arrived in North America, if they are accurately dated. A new study brings the age claim into question.
Published Welsh 'weird wonder' fossils add piece to puzzle of arthropod evolution



International team of researchers describe new fossil species discovered in fossil deposit near Llandrindod Wells in mid-Wales. The fossil, Mierridduryn bonniae, shares many features with Cambrian 'weird wonder' Opabinia, but is 40 million years younger. Robust phylogenetic analyses suggest that Mierridduryn is either the third opabiniid ever discovered, or is a distinct group that is key for understanding the evolution of the arthropod head.
Published Prehistoric predator? Artificial intelligence says no


Artificial intelligence has revealed that prehistoric footprints thought to be made by a vicious dinosaur predator were in fact from a timid herbivore.
Published Full decarbonization of U.S. aviation sector is within grasp


New research shows a pathway toward full decarbonization of U.S. aviation fuel use by substituting conventional jet fuel with sustainably produced biofuels. The study found that planting the grass miscanthus on 23.2 million hectares of existing marginal agricultural lands -- land that often lays fallow or is poor in soil quality -- across the United States would provide enough biomass feedstock to meet the liquid fuel demands of the U.S. aviation sector fully from biofuels, an amount expected to reach 30 billion gallons/year by 2040.
Published Oldest evidence of the controlled use of fire to cook food, researchers report



The remains of a huge carp fish mark the earliest signs of cooking by prehistoric human to 780,000 years ago, predating the available data by some 600,000 years, according to researchers.
Published Mimicking life: Breakthrough in non-living materials


Researchers have discovered a new process that uses fuel to control non-living materials, similar to what living cells do. The reaction cycle can easily be applied to a wide range of materials and its rate can be controlled -- a breakthrough in the emerging field of such reactions. The discovery is a step towards soft robotics; soft machines that can sense what is happening in their environment and respond accordingly.
Published Automated system to detect compressed air leaks on trains


Researchers have developed a proof-of-concept system to autonomously detect compressed air leaks on trains and relay the location of the leaks to mechanical personnel for repair. The automated system could reduce the time, costs and labor needed to find and repair air leaks, and it could lower the locomotive industry's overall fuel consumption and exhaust emissions.
Published New pterosaur species found in sub-Saharan Africa



With wings spanning nearly 16 feet, a new species of pterosaurs has been identified from the Atlantic coast of Angola.
