(McGill University) Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, according to a new study led by an international team of researchers, including McGill University Professor Hans Larsson. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years. The findings, published in iScience, support that dinosaurs evolved flight in several different ways before modern birds evolved.
Those of us who reject the idea that mankind controls Earth’s thermostat do so for many reasons. As yet there exists no physical evidence to link the steady growth of carbon dioxide beginning in the 1950s with the erratic atmospheric…
Researchers who analyzed thousands of documents covering a 300-year span of plague outbreaks in London, England, have estimated that the disease spread four times faster in the 17th century than it had in the 14th century.

(Max Planck Institute for the Science of Human History) Using luminescence dating of ancient river sediments, a new study published in Quaternary Science Reviews presents evidence for river activity at Nal Quarry in the central Thar Desert starting from approx. 173 thousand years ago. These findings represent the oldest directly dated phase of river activity in the region and indicate Stone Age populations lived in a distinctly different Thar Desert landscape than we encounter today.
(Penn State) Rocks from the Rio Grande continental rift have provided a rare snapshot of active geology deep inside Earth’s crust, revealing new evidence for how continents remain stable over billions of years, according to a team of scientists.
A study done by Irish and U.S.-based researchers is calling into question the efficacy of renewable energy sources such as wind and solar in dealing with the so-called climate crisis. In fact, the study found that such energy sources are…
