Now, a team of engineers and geologists brings a new theory to the table — a hydraulic lift device that would have floated the heavy stones up through the middle of Egypt’s oldest pyramid using stored water. Water from ancient streams flowed into a system of trenches and tunnels that surrounded the Step Pyramid, according to the study team. The shaft within the Step Pyramid is connected to a 200-meter-long (656-foot-long) underground tunnel that connects to another vertical shaft outside the pyramid. Conversely, a moderate-sized hydraulic lift can raise 50 to 100 tons. “It doesn’t mean (the hydraulic lift device) wasn’t used,” she added.

London CNN —Spanish artist Almudena Romero is known for creating artworks that use plants as her medium. Almudena Romero “The Pigment Change” series has a chapter called “Family Album,” in which Romero projects a negative onto live watercress, using the plants’ natural photosynthesis to create areas of light and dark. Almudena Romero This artwork, which was exhibited this year on International Women’s Day, is a tribute to a childhood friend. Almudena Romero Romero questions the long-term future of conventional photographic film, when the materials needed to produce it are limited.
