An international team of scientists led by the University of Birmingham adopted the novel approach of applying the forensic characterization of a single ancient, bright star called ν Indi as a probe of the history of the Milky Way Galaxy. Stars carry “fossilized records” of their histories and hence the environments in which they formed. ...
Clues from Canadian rocks formed billions of years ago reveal a previously unknown loss of life even greater than that of the mass extinction of the dinosaurs 65 million years ago. The Earth lost nearly three-quarters of its plant and animal species in a huge die-off in the ancient biosphere. Rather than prowling animals, this ...
Scientists have developed a new method for detecting traces of primordial life in ancient rock formations using potassium. The method relies on searching for high concentrations of potassium in ancient sedimentary rocks, rather than traditional methods that look for carbon, sulfur, or nitrogen—which can appear in ancient rocks through processes unrelated to ancient life. University ...
Two fossils, one found more than a century ago and another collected 70 years later, were the clues that enabled a Masters student to identify a new species of prehistoric crocodile. The new species of crocodile has been described from opalized fossils found at Lightning Ridge in NSW, Australia, from a fossil dug up more than ...
Archaeologists learn about the past by piecing together artifacts from material culture: The tools, artwork, and architecture left behind that tell us how ancient humans lived. But imagine being able to study their ancient DNA as well to learn about how different groups of people were related to each other, where they came from, or ...
Even with a highly skilled neurosurgeon, the most effective anesthesia, and all the other advances of modern medicine, most of us would cringe at the thought of undergoing cranial surgery today. After all, who needs a hole in their head? Yet for thousands of years, trepanation — the act of scraping, cutting, or drilling an ...
This is the story of how pigs defeated elephants in battles. We know that animals such as horses, elephants, cats, dogs, monkeys, and even rhinos have been used in ancient and modern warfare. But who would have thought that pigs (war pigs) would have been used as a weapon of war in ancient times? During ...
On a tiny Indonesian island, a large number of ancient cave paintings have been discovered. The island is called Kisar, which measures just 81 square kilometers, and was previously unexplored by archaeologists. Now, a team of researchers from The Australian National University (ANU) have found a total of 28 rock art sites. The sites date ...
