Medieval People Drank More Beer Than Water
Due to unsafe drinking water, beer was the preferred daily beverage—even for children. It contained low alcohol levels but was safer than contaminated water.
A new study explores how advanced extraterrestrial civilizations might evolve into “stellivores,” harvesting stellar mass for energy beyond the Kardashev Scale's limits. Researchers suggest observing “accreting binaries” to detect potential tech
NASA’s Webb Telescope recently studied tiny dust particles in space, likely from asteroids and comets. These particles could reveal insights into planetary formation and the spread of essential life materials. Scientists aim to uncover cosmic processes
A new screw-driven robot prototype can autonomously navigate and mine rocky planets like Mars using Archimedean screws, ideal for challenging surfaces like sand and snow. Developed with EU support, it holds potential for extraterrestrial mining missions.
0.5% of the male population are descended from Genghis Khan. (Scientists did a study in 2003 showing that about 16 million dudes share a Y chromosome with the famous Emperor.)
If you were to lay out all the blood vessels in the human body end to end, they would stretch over 60,000 miles. That's enough to circle the Earth more than twice!
