(via sciencedaily.com) Original source Paleontologists have identified a new genus of fossil goby, revealing evolutionary secrets of a lineage that stretches back millions of years.
Published Ancient ocean slowdown warns of future climate chaos
(via sciencedaily.com) Original source When it comes to the ocean's response to global warming, we're not in entirely uncharted waters. A new study shows that episodes of extreme heat in Earth's past caused the exchange of waters from the surface to the deep ocean to decline.
Published No bones about it: 100-million-year-old bones reveal new species of pterosaur
(via sciencedaily.com) Original source New research has identified 100-million-year-old fossilized bones discovered in western Queensland as belonging to a newly identified species of pterosaur, which was a formidable flying reptile that lived among the dinosaurs.
Published Scientists unlock secrets of how archaea, the third domain of life, makes energy
(via sciencedaily.com) Original source An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how these tiny lifeforms make energy by consuming and producing hydrogen. This simple but dependable strategy has allowed them to thrive in some of Earth's most hostile environments for billions of years.
Published Lazy predator: A new species of mountain pitviper from China
(via sciencedaily.com) Original source Researchers have discovered a new species of medium-sized venomous snake in Yunnan, China. Ovophis jenkinsi is dark brownish-grey in color with trapezoidal patches on its back. It is endemic to China's Yingjiang County and is not difficult to find in the wild. In the future, researchers plan to collect more information about this new species, including its appearance, distribution, and habits.
Published Novel Genetic Clock discovers oldest known marine plant
(via sciencedaily.com) Original source An international research team has discovered the oldest known marine plant using a novel genetic clock. This 1400-year-old seagrass clone from the Baltic Sea dates back to the Migration Period. The research project is a significant step towards better understanding and protecting marine ecosystems.
Published Tiny new species of great ape lived in Germany 11 million years ago
(via sciencedaily.com) Original source Ancient apes in Germany co-existed by partitioning resources in their environment, according to a new study.
Published Tiny roundworms carve out unique parasitic niche inside pseudoscorpion's protective covering
(via sciencedaily.com) Original source In a parasitic first, a Baltic amber specimen has revealed that millions of years ago tiny worms known as nematodes were living inside of and feeding on the outer protective layer of pseudoscorpions.
Published Fishy mystery of marine reptile solved
(via sciencedaily.com) Original source The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
Published 'Missing' early sea sponges discovered
(via sciencedaily.com) Original source Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.
Published Combining pest treatments may be key to helping honey bees survive the winter
(via sciencedaily.com) Original source Winters can be tough on managed honey bee colonies, with beekeepers in the United States reporting that one-third of their colonies die each winter. A new study has found that using not one but multiple pest treatments may help bees make it to spring.
Published Gigantic Jurassic pterosaur fossil unearthed in Oxfordshire, UK
(via sciencedaily.com) Original source A team of palaeontologists has discovered a fossil of a gigantic flying reptile from the Jurassic period with an estimated wingspan of more than three metres -- making it one of the largest pterosaurs ever found from that era.
Published Frequent mowing puts poisonous weed into survival mode
(via sciencedaily.com) Original source A study has found that frequent mowing of Solanum elaeagnifolium, also known as silverleaf nightshade, may help create a 'superweed.' A professor of entomology and plant pathology has been studying silverleaf nightshade for more than a decade. New findings have shown that the more silverleaf nightshade was mowed, the more it developed ways to avoid destruction. The taproot went down further, nearly 5 feet deep, in the first generation of mowed plants. More spikes popped out on the stem as a defense against caterpillars feeding on the flowers. The flowers became more toxic to caterpillars, leading to less pressure from natural predators.
Published Urgent need for action now for increasing threat from invasive alien species
(via sciencedaily.com) Original source Urgent action now is needed to tackle the major and growing global issue of invasive alien species, says a team of 88 experts from 47 countries. The paper follows the (IPBES) thematic assessment report on invasive alien species and their control. The experts say co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.
Published Captivating blue-colored ant discovered in India's remote Siang Valley
(via sciencedaily.com) Original source A new species of blue ant was discovered in Yingku village in Arunachal Pradesh, Northeastern India. It was named Paraparatrechina neela, after the word 'neela' which means blue in various Indian languages. Its unique blue coloration makes it stand out among other ant species.
Published Mussels downstream of wastewater treatment plant contain radium, study reports
(via sciencedaily.com) Original source Burrowed into streambeds and rarely moving for their decades-long lifespans, freshwater mussels are biomonitors, meaning they indicate how clean their environment is, according to researchers. As the bivalves feed on organic matter and filter the water around them, their inner tissues and hard shells begin to reflect whatever is in their environment -- including radioactive particles.
Published 'Ugly' fossil places extinct saber-toothed cat on Texas coast
(via sciencedaily.com) Original source This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.
Published Origins of 'Welsh dragons' finally exposed by experts
(via sciencedaily.com) Original source A large fossil discovery has helped shed light on the history of dinosaurs in Wales.
