Archaeologists have long wondered how ancient workers accomplished such an architectural feat before the advent of large machinery like bulldozers and cranes. Because the pyramid sits near a long-gone branch of the Nile, researchers hypothesise that the ancient Egyptians utilised the water source to build the 62-metre-tall pyramid by designing a 'modern hydraulic system' comprising a dam, a water treatment plant and a hydraulic freight elevator, all powered by the river. They posit that the mysterious Gisr el-Mudir enclosure near the pyramid worked as a structure that captured sediment and water.

The Space Force is launching lasers into orbit
The Space Force aims to better pinpoint the location of Earth's true centre using lasers on GPS satellites, slated to launch in 2025. A set of Laser Retroreflector Arrays, or LRAS, will be installed onto two GPS III satellites, SV9 and SV10, as part of NASA's Space Geodesy Program. The lasers are designed to make precise sub-centimetre measurements using a technique called Satellite Laser Ranging, which will allow researchers to more accurately determine Earth's centre.
Eating too much sugar may accelerate cellular ageing
A nutrient-rich diet with few added sugars may slow the rate of biological ageing in women. Scientists found that middle-aged women who ate more foods packed with vitamins, minerals and antioxidants had 'younger looking' cells than those who consumed less nutrient-rich diets.
