Published Fossil named 'Attenborough's strange bird' was the first in its kind without teeth



A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.
Published Modeling the origins of life: New evidence for an 'RNA World'



Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals



A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published Slimming down a colossal fossil whale



A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
Published Change in gene code may explain how human ancestors lost tails



A genetic change in our ancient ancestors may partly explain why humans don't have tails like monkeys.
Published Stronger storms free more nutrients from mud flats



If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas.
Published High resolution techniques reveal clues in 3.5 billion-year-old biomass



To learn about the first organisms on our planet, researchers have to analyze the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time. A research team has now found new clues about the formation and composition of this ancient biomass, providing insights into the earliest ecosystems on Earth.
Published Utah's Bonneville Salt Flats has long been in flux



It has been long assumed that Utah's Bonneville Salt Flats was formed as its ancient namesake lake dried up 13,000 years ago. But new research has gutted that narrative, determining these crusts did not form until several thousand years after Lake Bonneville disappeared, which could have important implications for managing this feature that has been shrinking for decades to the dismay of the racing community and others who revere the saline pan 100 miles west of Salt Lake City. Relying on radiocarbon analysis of pollen found in salt cores, the study concludes the salt began accumulating between 5,400 and 3,500 years ago, demonstrating how this geological feature is not a permanent fixture on the landscape.
Published New detection method aims to warn of landslide tsunamis



Researchers have devised a way to remotely detect large landslides within minutes of occurrence and to quickly determine whether they are close to open water and present a tsunami hazard.
Published Butterfly and moth genomes mostly unchanged despite 250 million years of evolution



Comparison of over 200 high-quality butterfly and moth genomes reveals key insights into their biology, evolution and diversification over the last 250 million years, as well as clues for conservation.
Published An awkward family reunion: Sea monsters are our cousins



The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling vital functions like blood pressure and heart rate -- of both sea lampreys and humans is built using an extraordinarily similar molecular and genetic toolkit.
Published Did neanderthals use glue? Researchers find evidence that sticks



Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought.
Published Mystery solved: The oldest fossil reptile from the alps is an historical forgery



Palaeontological analysis shows that a renowned fossil thought to show soft tissue preservation is in fact just paint. The fossil discovered in 1931 was thought to be an important specimen for understanding early reptile evolution. While not all of the celebrated fossil is a forgery, scientists urge caution in how the fossil is utilized in future.
Published Ancient retroviruses played a key role in the evolution of vertebrate brains



Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is essential for myelin production in mammals, amphibians, and fish. The gene sequence, which they dubbed 'RetroMyelin,' is likely a result of ancient viral infection, and comparisons of RetroMyelin in mammals, amphibians, and fish suggest that retroviral infection and genome-invasion events occurred separately in each of these groups.
Published Anthropologists' research unveils early stone plaza in the Andes



Located at the Callacpuma archaeological site in the Cajamarca Basin of northern Peru, the plaza is built with large, vertically placed megalithic stones -- a construction method previously unseen in the Andes.
Published Some Pre-Roman humans were buried with dogs, horses and other animals



Some people from an ancient community in what is now northern Italy were interred with animals and animal parts from species such as dogs, horses and pigs. The reasons remain mysterious, but might indicate an enduring companion relationship between these humans and animals, or religious sacrificial practices, according to a new study.
Published Great apes playfully tease each other



Babies playfully tease others as young as eight months of age. Since language is not required for this behavior, similar kinds of playful teasing might be present in non-human animals. Now cognitive biologists and primatologists have documented playful teasing in four species of great apes. Like joking behavior in humans, ape teasing is provocative, persistent, and includes elements of surprise and play. Because all four great ape species used playful teasing, it is likely that the prerequisites for humor evolved in the human lineage at least 13 million years ago.
Published Archaeologists discover oldest known bead in the Americas



The bead found at the La Prele Mammoth site in Wyoming's Converse County is about 12,940 years old and made of bone from a hare.
Published The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly



Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
Published Surprisingly vibrant color of 12-million-year-old snail shells



Snail shells are often colorful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed. Residues of ancient color patterns are therefore very rare. This makes a new discovery all the more astonishing: researchers found pigments in twelve-million-year-old fossilized snail shells.
