93%Seven complete specimens of new flower, all 100 million years old
A Triceratops or Tyrannosaurus rex bulling its way through a pine forest likely dislodged flowers that 100 million years later have been identified in their fossilized form as a new species of tree.George Poinar Jr., professor emeritus in Oregon State University's College of Science, said it's the first time seven complete flowers of this age have been reported in a single study. The flowers range from 3.4 to 5 millimeters in diameter, necessitating study under a microscope... read more
83%Dino-killing asteroid could have thrust Earth into two years of darkness
Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs.www.sciencedaily.com/releas...
91%Research has solved the mystery of how the first animals appeared on Earth
Research led by The Australian National University (ANU) has solved the mystery of how the first animals appeared on Earth, a pivotal moment for the planet without which humans would not exist.Lead researcher Associate Professor Jochen Brocks said the team found the answer in ancient sedimentary rocks from central Australia."We crushed these rocks to powder and extracted molecules of ancient organisms from them," said Dr Brocks from the ANU Research School of Earth Sciences... read more
85%‘Vanished’ people may live on in the U.S. Southwest
In the late 1200s, the Ancestral Puebloan people of what is today the Four Corners Region of the U.S. Southwest suddenly vanished. For centuries, the culture—also known as the Anasazi—had grown maize and built elaborate villages and sandstone castles. Then, it was gone. Now, using DNA extracted from ancient turkeys, researchers say they have new insights into where these mysterious people went, though some experts are skeptical of the findings... read more
91%Unique imaging of a dinosaur's skull tells evolutionary tale
Collaboration creates highest-resolution scan of a large tyrannosaur skullResearchers 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. The results add a new piece to the puzzle of how these bone-crushing top predators evolved over millions of years... read more
95%Mystery of 8,500-year-old copper-making event revealed through materials science
An international team of archaeological scientists have put an end to the more than half-a-century old claim about the earliest copper smelting event at the Late Neolithic site of Çatalhöyük in central Turkey -- one of the world's best-studied prehistoric archaeological sites.Scholars have been hotly debating the origins and spread of metallurgy for decades, mainly due to the relationship this technology had with the rise of social complexity and economy of the world's first civilisations in... read more
97%Experiments cast doubt on theory of how Earth was formed
New geochemical research indicates that existing theories of the formation of the Earth may be mistaken. The results of experiments to show how zinc (Zn) relates to sulphur (S) under the conditions present at the time of the formation of the Earth more than 4 billion years ago, indicate that there is a substantial quantity of Zn in the Earth's core, whereas previously there had been thought to be none. This implies that the building blocks of the Earth must be different to what has been supposed... read more
82%Ancient pottery reveals insights on Iroquoian population's power in 16th century
An innovative study demonstrates how decorations on ancient pottery can be used to discover new evidence for how groups interacted across large regions.www.sciencedaily.com/releas...
96%Analysis of Roman coins tells of Hannibal's defeat and Rome's rise
The defeat by the ancient Romans of Hannibal, despite the Carthaginian leader’s famous feat of marching his army – complete with war elephants – over the Pyrenees and Alps into Italy, also meant that the Romans captured the silver mines of the Iberian peninsula, bringing so much silver into the Roman empire that it can be traced through the coinage.www.theguardian.com/science...?
81%The Real Story Behind the "House of Jesus' Apostles" Discovery
The "lost home of Jesus' apostles" has just been found, according to a recent Israeli newspaper report. Yet while the actual discovery is not nearly as sensational as many headlines suggest, the new results are adding very interesting fuel to an ongoing debate about the location of one of the most important cities in the New Testament. news.nationalgeographic.com...
