Fossils embedded in rock reveal intriguing details about animals, plants and other life-forms that once called Earth home. ConsequencesCrawford Lake in Ontario is the geological site that best reflects a new epoch recognizing the impact of human activity on Earth, said geologists of the Anthropocene Working Group. The Anthropocene Working Group determined in 2016 that the epoch began around 1950 — the start of the era of nuclear testing. The international research group says that Crawford Lake in Ontario best charts humanity’s impact on Earth. Back then, it took 10 hours to relay a single image to Earth — incredibly slow by today’s standards.

Explore the universe with news on fascinating discoveries, scientific advancements and more.CNN —Researchers using a cutting-edge technique have discovered hidden details in two ancient Egyptian paintings in the Theban Necropolis, near the River Nile, that date back more than 3,000 years. Using portable chemical imaging technology, the researchers identified alterations made by the artists that are rare in Egyptian paintings, commonly thought to be the product of highly formalized workflows. We want to understand how these paintings were made.”X-ray fluorescence in chemical imaging technology helps to reveal alterations made in Egyptian tomb paintings that may not seem obvious to the naked eye. “It demonstrates the potential value of quantitative data, obtained through scientific analysis, for a more comprehensive and less subjective interpretation of ancient Egyptian art,” she said. “And the adaption of portable (X-ray) instruments as mobile devices designed for use in the field is a very exciting advancement in the study of ancient Egyptian wall paintings.”
