Virginia Mason announced today Edmonds Family Medicine, the largest family practice group serving north King and south Snohomish counties, plans to become part of the Virginia Mason Health System early next year.
Rural counties continue to rank lowest among counties across the U.S., in terms of health outcomes. A group of national organizations including the Robert Wood Johnson Foundation and the National 4-H Council are leading the way to close the rural health gap.
The two teeth are from small, rat-like creatures that lived 145 million years ago in the shadow of the dinosaurs. They are the earliest undisputed fossils of mammals belonging to the line that led to human beings.
Human teeth hold vital information about Vitamin D deficiency, a serious but often hidden condition that can now be identified by a simple dental X-ray, McMaster anthropologists Lori D’Ortenzio and Megan Brickley have found.
A team of scientists and students at the University of Rhode Island is inching closer to revealing how a group of animals from the Late Triassic went extinct
Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54 million-year-old sea turtle hatchling. The work provides direct evidence that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago.
According to NAU researcher Chris Doughty, these large animals are important not for the quantity of dung they produce, but for their ability to move long distances across landscapes, effectively mixing the nutrients.
UT Southwestern Medical Center researchers today published a 3-D atomic structure of the ion channel found in mammals that is implicated in a rare, inherited neurodegenerative disease in humans.
CIPRES, for CyberInfrastructure for Phylogenetic RESearch, is a web-based portal or “gateway” launched at the San Diego Supercomputer Center (SDSC) at UC San Diego that allows researchers to explore evolutionary connections among species using supercomputers provided by the National Science Foundation’s (NSF’s) XSEDE (eXtreme Science and Engineering Discovery Environment) project.
A new study on an exceptionally preserved salamander from the Eocene of France reveals that its soft organs are conserved under its skin and bones. Organs preserved in three dimensions include the lung, nerves, gut, and within it, the last meal of the animal, according to a study published in the peer-reviewed journal PeerJ.
Ancient DNA extracted from fossil bones and museum specimens has shed new light on the mysterious loss of the Tasmanian tiger (thylacine) from Australia’s mainland.
The first large-scale study of ancient human DNA from sub-Saharan Africa opens a long-awaited window into the identity of prehistoric populations in the region and how they moved around and replaced one another over the past 8,000 years.
Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study published in Systematic Biology.
Some big plant-eating dinosaurs roaming present-day Utah some 75 million years ago were slurping up crustaceans on the side, a behavior that may have been tied to reproductive activities, says a new University of Colorado Boulder study.
In an effort to settle the debate about the origin of dog domestication, a technique that uses 3-D scans of fossils is helping researchers determine the difference between dogs and wolves.
Dr. Igor Ulitsky has found that ancient genes that lost their ability to make proteins were “recycled,” surviving across millennia – and species – by evolving to produce a type of RNA that regulates major biological processes. His findings could lead to treatments for a number of genetic diseases.
Scientists say that a large, now extinct, frog called Beelzebufo that lived about 68 million years ago in Madagascar would have been capable of eating small dinosaurs.
Missouri S&T geologist Dr. Wan Yang has devoted his academic career to unlocking the mysteries of thePermian mass extinction more than 250 million years ago. That geological odyssey now finds him leading an 11-institution consortium that’s been collectively awarded a $2.1 million National Science Foundation research grant.
UAB’s team of rehab psychologists provides care and pathways to better the quality of life for patients who suffer from a multitude of traumatic injuries.
Researchers at University of California San Diego School of Medicine and collaborators discovered a new kind of glycan (sugar chain) that survives even in a 4 million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept study, published September 11 in Proceedings of the National Academy of Sciences, sets the stage for unprecedented explorations of human origins and diet.
The fossilized plesiosaur Sankar Chatterjee found in 1984 is giving scientists a new understanding of convergent evolution between reptiles and mammals.
A new study led by the University of Southampton has shed light on the swimming style of plesiosaurs by creating a robot to mimic its movements.
A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there. The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region.
Researchers from the Naturalis Biodiversity Center in Leiden examined woolly rhino and modern rhino neck vertebrae from several European and American museum collections and noticed that the remains of woolly rhinos from the North Sea often possess a ‘cervical’ (neck) rib—in contrast to modern rhinos. The study, published in the open access journal PeerJ today, reports on the incidence of abnormal cervical vertebrae in woolly rhinos. Given the considerable birth defects that are associated with this condition, the researchers argue it is very possible that developmental abnormalities contributed towards the eventual extinction of these late Pleistocene rhinos.
Baleen whales are amongst the largest animals to have ever lived and yet very little is known about their breeding habits. One researcher’s second look at previously found baleen whale fossils from Japan provides new evidence of a now long-gone breeding ground of the extinct baleen whale Parietobalaena yamaokai dating back over 15 million years.
Researchers using Los Alamos’ unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done.
Two 160 million-year-old mammal fossils discovered in China show that the forerunners of mammals in the Jurassic Period evolved to glide and live in trees. With long limbs, long hand and foot fingers, and wing-like membranes for tree-to-tree gliding, Maiopatagium furculiferum and Vilevolodon diplomylos are the oldest known gliders in the long history of early mammals.
An international team of researchers has shown in unprecedented detail that prehistoric farmers took their animals away from permanent settlements to graze in more fertile areas – probably because of high demand for land locally.
Ten-year Jude Sparks’s accidental discovery in the Las Cruces desert led a New Mexico State University professor to a rare, mostly intact 1.2 million year-old stegomastodon skull. NMSU biology professor Peter Houde put together a team that worked for about a week to carefully unearth the skull.
Little is known about the origin and early evolution of the Notosuchia, hitherto unknown in the Jurassic period. New research on fossils from Madagascar, published in the peer-reviewed journal PeerJ by Italian and French paleontologists, begin to fill the gap in a million-year-long ghost lineage.
One popular theory about the Paleolithic cave paintings proposes that sites were chosen based on the acoustics in the caves. The originators of the theory reported a causal connection between the “points of resonance” in three French caves and the position of Paleolithic cave paintings. David Lubman, an acoustic scientist and fellow of ASA, will share some of the insights from his research during Acoustics ’17 Boston, held June 25-29, in Boston, Massachusetts.
How baleen whales became filter feeders is widely debated among scientists—but now anatomy researchers at NYIT College of Osteopathic Medicine may finally solve this mystery.
Dinosaurs' faces might have been much more sensitive than previously thought, and crucial to tasks from precision eating and testing nest temperature to combat and mating rituals, according to a University of Southampton study.
Ancestors of the iconic New Zealand Christmas Tree, Pōhutukawa, may have originated in Australia, new fossil research from the University of Adelaide suggests.
A North Dakota State University assistant professor has received a national award that will bring more than $500,000 to the geosciences department at NDSU and provide research opportunities for students.
An ancient otter tooth recently discovered in Mexico suggests certain mammals migrated across America during the Miocene geologic epoch, roughly 23 million to 5.3 million years ago. The new hypothesized route questions other theories such as migrations above Canada and through Panama, and has implications for a much larger biologic event — the Great American Biotic Interchange, when land bridges were formed and animals dispersed to and from North America and South America.
Paleontologists Adam Tomašových of the Slovak Academy of Sciences and Susan Kidwell of the University of Chicago examine a lost ecosystem of scallops and shelled marine organisms called brachiopods in a new study.
The Cleveland-Lloyd Dinosaur Quarry is the densest collection of Jurassic dinosaur fossils. Since its discovery in the 1920s, numerous hypotheses have been proposed to explain the origin of the quarry. Were the dinosaurs poisoned? Did they die due to drought? Were they trapped in quick sand? A new study suggests that the quarry represents numerous mortality events which brought the dinosaurs to the site over time, rather than a single fatal event.
Scientists are now confident animal life on solid ground started with a few short bursts of marine creatures making the leap from the oceans. New research at the University of Portsmouth also paints a clear picture of how animals rapidly spread out and changed once they made the leap.
An interdisciplinary study suggests that the strange creatures which lived in the Garden of the Ediacaran more than 540 million years ago before animals came on the scene may have been much more dynamic than experts have thought.
A Florida State- Oklahoma State research team found that T. rex could pulverize bones, chomping down with nearly 8,000 pounds of force.
The team’s findings, published today in eLife, shed light on how immune cells might be harnessed to someday help stimulate tissue regeneration in humans.
Around 66 million years ago, at the end of the Cretaceous period, a giant asteroid crashed into the present-day Gulf of Mexico, leading to the extinction of the non-avian dinosaurs. How plants were affected is less understood, but fossil records show that ferns were the first plants to recover many thousands of years afterward. Now, a team including Cornell researchers reports the discovery of the first fossilized flowers from South America, and perhaps the entire Southern Hemisphere, following the extinction event
New sauropod species is named Galeamopus pabsti by the same team which recently reinstated the brontosaurus as a distinct genus.
Studies of bones from Ice Age megafaunal animals across Eurasia and the Americas have revealed that major increases in environmental moisture occurred just before many species suddenly became extinct around 11-15,000 years ago. The persistent moisture resulting from melting permafrost and glaciers caused widespread glacial-age grasslands to be rapidly replaced by peatlands and bogs, fragmenting populations of large herbivore grazers.
A new facility at the University of Arkansas combines laser ablation and mass spectrometry for quick, efficient analysis of trace elements and radiogenic isotopes.
CT scans of fossils of the pre-mammalian reptile, Euchambersia, shows anatomical features, designed for venom production
The creature has a considerably shorter and stronger neck with larger muscles than the long graceful necks of others in its species.
Researchers from Canada, the U.S. and Italy uncover evidence that people in the Upper Paleolithic Period used stone spatulas to decorate the bodies of the dead with ochre
