Well-Preserved Embryo Found Inside Fossilized Dinosaur Egg
A rare look inside a fossilized dinosaur egg found in southern China has revealed an exquisitely preserved embryo -- and evidence suggesting that some of these prehistoric creatures had even more in common with modern birds than previously thought. F.....»»
New beetle species found pristinely preserved in fossilized dropping of dinosaur ancestor
Fossilized feces are common finds at paleontological dig sites and might actually contain hidden treasures. By scanning fossilized dung assigned to a close dinosaur relative from the Triassic period, scientists discovered a 230-million-year-old beetl.....»»
Ancient carved snake found in Finland
A pair of researchers from the University of Turku and the University of Helsinki, respectively, both in Finland, has found a well-preserved ancient carved snake at Järvensuo 1, a dig site in south-west Finland. In their paper published on the Cambr.....»»
Digging into the molecules of fossilized dinosaur eggshells
Dinosaurs roamed the Earth more than 65 million years ago, and paleontologists and amateur fossil hunters are still unearthing traces of them today. The minerals in fossilized eggs and shell fragments provide snapshots into these creatures' early liv.....»»
Study provides first genome-wide evidence for functional importance of unusual DNA structures
Some regions of the human genome where the DNA can fold into unusual three-dimensional structures called G-quadruplexes (G4s) show signs that they are preserved by natural selection. When G4s are located in the regulatory sequences that control how g.....»»
The evolution of axial patterning
Body axes are molecular coordinate systems along which regulatory genes are activated. These genes then activate the development of anatomical structures in correct locations in the embryo. Thus, the body ensures that we do not develop arms on our he.....»»
"Dragon man" fossil may replace Neanderthals as our closest relative
A near-perfectly preserved ancient human fossil known as the Harbin cranium sits in the Geoscience Museum in Hebei GEO University. The largest of known Homo skulls, scientists now say this skull represents a newly discovered human species named Homo.....»»
Dinosaurs Lived In the Arctic, Research Suggests
An array of tiny fossils suggests dinosaurs not only roamed the Arctic, but hatched and raised their young there too. The Guardian reports: While dinosaur fossils have previously been found in the Arctic, it was unclear whether they lived there year-.....»»
Multiple dinosaur species not only lived in the Arctic, they also nested there
In the 1950s, researchers made the first unexpected discoveries of dinosaur remains at frigid polar latitudes. Now, researchers reporting in the journal Current Biology on June 24 have uncovered the first convincing evidence that several species of d.....»»
New findings on body axis formation
In the animal kingdom, specific growth factors control body axis development. These signaling molecules are produced by a small group of cells at one end of the embryo to be distributed in a graded fashion toward the opposite pole. Through this proce.....»»
How do developing spinal cords choose "heads" or "tails"?
The progression from a round ball of cells to an embryo with a head and a tail is one of the most critical steps in an organism's development. But just how cells first start organizing themselves with directionality along this head-to-tail axis is ha.....»»
Profiling gene expression in plant embryos, one nucleus at a time
Following fertilization, early plant embryos arise through a rapid initial diversification of their component cell types. As a result, this series of coordinated cell divisions rapidly sculpts the embryo's body plan. The developmental phenomenon in q.....»»
Study identifies trigger for "head-to-tail" axis development in human embryo
Scientists have identified key molecular events in the developing human embryo between days 7 and 14—one of the most mysterious, yet critical, stages of our development......»»
The most ancient ice in the Alps will be preserved in Antarctica
The Ice Memory international mission on Monte Rosa has been accomplished. After working for five days at 4,500 meters in the accumulation zone of the Grenzgletscher, the glacier saddle of Colle Gnifetti, scientists extracted three shallow ice cores (.....»»
Trace fossils, the most inconspicuous bite-sized window into ancient worlds
“One animal could have made thousands of traces during its lifetime, but only left one skeleton." Enlarge / It may not look like much, but you can actually learn a lot from a fossilized leaf that preserves insect damage. (credit: Donovan et. a.....»»

Fossilised moa poo paints a picture of the past
Knowledge of the diets of New Zealand's extinct moa (Aves: Dinornithiformes) comes from careful analysis of moa coprolites (fossilized poop) and gizzard contents. Moa coprolites and gizzard contents can be dissected and analyzed under the microscope.....»»
This Range Rover Classic restomod runs on Tesla power
An intriguing and much more unusual alternative to the six-figure supercar. At first glance, this just looks like a very well-preserved 1995 Range Rover Classic. But it's been rebuilt from the chassi.....»»
Young T. rexes had a powerful bite, capable of exerting one-sixth the force of an adult
Jack Tseng loves bone-crunching animals—hyenas are his favorite—so when paleontologist Joseph Peterson discovered fossilized dinosaur bones that had teeth marks from a juvenile Tyrannosaurus rex, Tseng decided to try to replicate the bite marks a.....»»
A fiery past sheds new light on the future of global climate change
Centuries-old smoke particles preserved in the ice reveal a fiery past in the Southern Hemisphere and shed new light on the future impacts of global climate change, according to new research published in Science Advances......»»
