Concrete usually adds to the world’s carbon burden, but a new formula absorbed CO2 while becoming stronger than a conventional mix. Researchers at Mepco Schlenk Engineering College in India developed the concrete by combining two naturally derived materials: porous zeolite and bamboo biochar. Tests described in Carbon Research suggest the blend could give infrastructure a […]
Scientists Create Stronger Concrete That Absorbs CO2 From the Air

Stacked Mummies Reveal 700 Years of Changing Burial Rituals in Ancient Egypt
The shift from placing mummies individually to stacking bodies in a Theban tomb shows how burial practices and their symbolic meanings changed over time. In tomb TT 209, an ancient Egyptian burial place in the Theban Necropolis opposite Luxor, four human mummies and a mummified dog were buried one above another. The dog rested directly […]
Hidden Toxic Metal Pollution Is Hitting Bumblebees Much Harder Than Honeybees
Bumblebees carried more heavy metals than honeybees sharing the same landscape, suggesting that pollution exposure can vary substantially between bee species. Bumblebees living beside honeybee colonies in Cambridgeshire brought back pollen with far higher levels of toxic metals. For most of the metals tested, concentrations were between two and seven times those in honeybee pollen, […]
