A soil-dwelling microbe has shown a surprising ability to trap carbon dioxide and turn it into rock. Scientists have discovered that Bacillus megaterium, a common bacterium long known for its role in biotechnology, can convert CO₂ gas into solid calcium carbonate with an efficiency rarely seen in either nature or industry. The process, recently detailed in a study led by …

A new study, published in the Cambridge Archaeological Journal by Dr. Esther Jacobson-Tepfer, reveals an astonishing transformation in elk images in 12,000 years of Altai rock art in western Mongolia. Once drawn in realistic detail, elk gradually evolved into stylized, nearly unrecognizable wolf-like figures, reflecting deep transformations of environment, mobility, and identity. Stylized elk.

For the past few weeks, I have been wearing a necklace that was a gift from my mother, Juliet, on my wedding day. She repurposed a brooch she herself had inherited into a pendant for me: a finely-wrought gold dragon holding a glowing red little ruby in its mouth. It’s beautiful and I have felt strangely compelled to wear it …

The ancient meteor impact that formed Arizona’s Barringer Crater sent shock waves through the Grand Canyon — likely triggering a landslide that dammed the Colorado River, a new study suggests. Barringer Crater, also called Meteor Crater, formed between 53,000 and 63,000 years ago, when a giant cosmic “curveball” punched a hole in Earth’s surface. The force of the impact traveled …

A discovery in Egypt has provided an extraordinary glimpse into the ancient art of winemaking. Archaeologists recently unearthed 5,000-year-old sealed wine jars in the tomb of Queen Meret-Neith at Abydos, one of the earliest known royal burial sites in Egypt. This discovery not only offers a tangible link to early winemaking but also sheds light on the advanced techniques used …
