Exquisitely preserved embryo found inside fossilized dinosaur egg
A 72- to 66-million-year-old embryo found inside a fossilized dinosaur egg sheds new light on the link between the behavior of modern birds and dinosaurs, according to a new study......»»
First-ever artificial cell nuclei created in living egg from purified DNA injection
A research group is the first in the world to succeed in constructing artificial cell nuclei by injecting purified DNA solution instead of sperm into living mouse eggs. Their findings are published in the journal Genes to Cells......»»
Nanopillars create tiny openings in the nucleus without damaging cells
Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells.....»»
New insights into sauropod evolution: Discovery of tail clubs in India
A new University of Michigan study of dinosaur fossils from India has revealed that the sauropod dinosaur Kotasaurus yamanpalliensis wielded a bony tail club......»»
Discovery of 3,775-year-old preserved log supports "wood vaulting" as a climate solution
A new study published in the journal Science suggests that an ordinary old log could help refine strategies to tackle climate change......»»
Studying fossil extraction on Native lands and exploring the depths of untold histories
In 2019, historian Lukas Rieppel published a book about the history of dinosaur fossils and their excavation in the late 1800s to create museum displays......»»
Magnifying deep space through the "Carousel Lens"—rare alignment offers unique opportunity to study cosmology
In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a massive cluster-scale gravitational lens system that.....»»
Ethics of biobanking for conservation: Researchers adjust ethical assessment tool for the use of genome research banks
In the face of the global biodiversity crisis, more and more biobanks are being set up to safeguard and potentially restore genetic diversity. Preserved tissue or cells allow scientists and conservationists to overcome spatial and even temporal fragm.....»»
Trilobite fossils from upstate New York reveal "extra" set of legs
A new study finds that a trilobite species with exceptionally well-preserved fossils from upstate New York has an additional set of legs underneath its head. The research, led by the American Museum of Natural History and Nanjing University in China,.....»»
Genomic analysis confirms the uniqueness of Iberian red deer in Europe
A genome study of more than 700 European red deer has identified four distribution areas on the continent (Norway, Scotland, Spain and Central Europe), each with their own genetic characteristics that need to be preserved.....»»
Archaeologists discover an ancient Neanderthal lineage that remained isolated for over 50,000 years
A fossilized Neanderthal discovered in a cave system in the Rhône Valley, France, represents an ancient and previously undescribed lineage that diverged from other currently known Neanderthals around 100,000 years ago and remained genetically isolat.....»»
Large theropod dinosaurs thrived near South Pole, Australian tracks show
A discovery of dinosaur tracks on Australia's southern coast—dating back to the Early Cretaceous when Australia was still connected to Antarctica—indicates that large theropod dinosaurs thrived in this polar environment, prowling the river floodp.....»»
Ancient viral genomes preserved in glaciers reveal climate history—and how viruses adapt to climate change
As humans alter the planet's climate and ecosystems, scientists are looking to Earth's history to help predict what may unfold from climate change. To this end, massive ice structures like glaciers serve as nature's freezers, archiving detailed recor.....»»
South Korea court to rule on embryo plaintiff climate case
A groundbreaking climate case brought against the South Korean government by young environmental activists who named an embryo as a lead plaintiff is set to be decided Thursday by the country's Constitutional Court......»»
Microscopic fossilized shells reveal ancient climate change patterns
At the end of the Paleocene and beginning of the Eocene epochs, between 59 to 51 million years ago, Earth experienced dramatic warming periods, both gradual periods stretching millions of years and sudden warming events known as hyperthermals......»»
Locked in a glacier: Virus adaptations to extreme weather provide climate change insights
Ancient viruses preserved in glacial ice hold valuable information about changes in Earth's climate, a new study suggests......»»
Matching dinosaur footprints found on opposite sides of the Atlantic Ocean
An international team of researchers led by SMU paleontologist Louis L. Jacobs has found matching sets of Early Cretaceous dinosaur footprints on what are now two different continents......»»
Paleontologists discover new predatory dinosaur with a distinctive "eyebrow"
Theropod dinosaurs are one of the most important large groups of dinosaurs, including well-known predators, such as Tyrannosaurus and Allosaurus, as well as modern birds. A variety of theropods are known from the Mesozoic Era, the age of the dinosaur.....»»
Fossil hotspots in Africa obscure a more complete picture of human evolution, study says
Much of the early human fossil record originates from just a few places in Africa, where favorable geological conditions have preserved a trove of fossils used by scientists to reconstruct the story of human evolution......»»
Using dental growth rings scientists reveal differences in growth patterns between ancient and modern mammals
A study published in Science Advances reveals how early mammals grew and developed during their pivotal Jurassic radiation. Using a technique called synchrotron X-ray tomography to image growth rings in fossilized tooth roots, the researchers were ab.....»»
New species of tyrannosaurid dinosaur identified in China
A team of paleontologists at the Zhejiang Museum of Natural History in China reports a new species of tyrannosaurid dinosaur. Their find is published in the journal Scientific Reports......»»
