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......»»
Discovery of oldest 3D-preserved microorganisms
For the first time ever, researchers have been able to study the form of microorganisms from the early days of evolution some 1.5 billion years ago. These microorganisms are of exceptional importance for our understanding of the development of early.....»»
Q&A: Research with embryo models needs legal clarity
Science often runs ahead of legislation—and this is now also true for research on embryo-like cell aggregates from human stem cells. Bioethicist Alessandro Blasimme of ETH Zurich explains why this controversial topic calls for legal clarity......»»
‘Embryo Models’ Challenge the Legal, Ethical, and Biological Concepts of an "Embryo"
With constructs built entirely from stem cells, researchers can revolutionize scientific understanding of human development. But how close is too close?.....»»
Mammal bites dinosaur in "once-in-a-lifetime" fossil find
A badger-like mammal was sinking its teeth into the ribs of a dinosaur three times its size when they were buried in volcanic ash 125 million years ago, capturing the pair in a deadly embrace......»»
Hitting reset to start a new embryo
New work by scientists in the U.S. and China shows how a fertilized egg cell, or zygote, hits "reset" so that the newly formed embryo can develop according to its own genetic program. The study was published July 17 in Nature......»»

Cell communication: Wnt signaling interpreted differently depending on receiving cell and signal duration
The same message can be interpreted differently by different individuals; also true among cells. This is shown by researchers at Linköping University who studied cell communication through Wnt signaling, which plays a decisive role in embryo develop.....»»

Unusual fossil shows rare evidence of a mammal attacking a dinosaur
Canadian and Chinese scientists have described an unusual fossil from around 125 million years ago that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur......»»
An Ancient Battle Is Playing Out in the DNA of Every Embryo
Millions of years ago, retroviruses invaded the human genome. Today some of these viral remnants threaten the developing embryo, while others fight to defend it......»»
A key function for tight junctions in embryo models
As a human embryo grows, a set of molecules directs cells as they multiply and take on specific identities and spatial positions within the embryo. In one crucial step known as gastrulation, these signaling molecules guide a single layer of embryonic.....»»
Preserved presolar silicate grains found in Ryugu samples
A large international team of space scientists and geochemists has found preserved presolar silicate grains in surface samples collected from the Ryugu asteroid by the Japanese space probe Hayabusa2 in 2018 and 2019 and returned to Earth in 2020. In.....»»

The rise and fall of the Roman empire preserved in pollen
Sediments at the bottom of the ocean can offer a window into the past, indicating environmental conditions not just from the sea but washed in from terrestrial runoff, as well as preserving the flora and fauna of the time. Scientists access this know.....»»
Smelling in stereo—a surprising find on a fossilized shark
Fossils and modern experiments are telling us what a shark's nose knows. Enlarge / Artist's reconstruction of the shark as it once lived. (credit: Klug et. al.) Sharks are largely cartilaginous, a body structure that oft.....»»
Fossils reveal how ancient birds molted, could explain why modern birds survived while other dinosaurs died
Every bird you've ever seen—every robin, every pigeon, every penguin at the zoo—is a living dinosaur. Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at th.....»»
Fossilized beaches help scientists understand impacts of past global warming
Fossilized beaches along the UK coastline have enabled scientists to demonstrate for the first time how melting Antarctic ice sheets impacted global sea levels during a period of pronounced climate warming more than 100,000 years ago......»»
