A new study suggests that the Step Pyramid of Djoser in Egypt was built using a hydraulic lift around 4,500 years ago. This would be earlier than previously thought for major hydraulic systems. The pyramid’s design, waterways, and interior architecture all point to the use of a hydraulic system. The study, published in PLOS ONE, … Read more
What a fascinating article! Tycho Brahe, an astronomer and alchemist, was a true Renaissance man. His discovery of a supernova in 1572 led to his appointment as the royal astronomer for King Frederick II of Denmark and Norway, which enabled him to build his observatory on the island of Ven.

The new spacesuit urine filtration system by Cornell researchers recycles astronauts’ urine into drinkable water, aiming to improve comfort and efficiency on future Moon and Mars missions. Currently, astronauts must relieve themselves inside their spacesuits during spacewalks, which is uncomfortable, unhygienic, and wasteful. To address this issue, Cornell researchers designed a novel urine collection and … Read more
Antimatter detected on International Space Station challenges our understanding of physics Eight years ago, the International Space Station (ISS) detected antimatter particles that defy our current knowledge of physics. Researchers propose that cosmic “fireballs” could explain these mysterious particles. The ISS’s Alpha Magnetic Spectrometer (AMS-02) detected around 10 antihelium nuclei, which are antimatter versions of … Read more
