This week, the first-ever archaeological survey in space was carried out on the ISS, we investigated if the Egyptians really built their oldest pyramid with a hydraulic lift, and we explained why people are so excited about Perseverance’s “possible biosignature” discovery on Mars. Finally, we asked why we believe in urban legends like the Russian sleep experiment.Subscribe to the IFLScience newsletter for all the biggest science news delivered straight to your inbox every Wednesday and Saturday. "World’s Oldest Calendar" May Depict Catastrophic Comet Impact 13,000 Years AgoA cataclysmic comet impact 13,000 years ago may have sparked the rise of civilization, according to the authors of a new study. The event – which many scientists believe never happened – may even be documented at the world-famous site of Göbekli Tepe, forming part of a series of carvings that the researchers say represent the world’s oldest solar calendar.

According to the authors, the mind-blowing system enabled enormous building blocks to be floated from the floor to the pyramid's summit via a central shaft, like lava flowing upwards through a volcano - yet archaeologists remain unconvinced.

Nicknamed Cheyava Falls, the arrowhead-shaped rock is the most promising find in the search for ancient life on Mars yet. There are structures visible in the rock that are consistent with being modified by microorganisms – it doesn’t mean that this is a discovery of life, but there is plenty to be excited about.

The implantation of a total artificial heart (TAH) is a proposed solution to help people with heart failure who need a heart transplant and is currently seen as a bridge to heart transplant in severe cases of heart failure.

But what makes stories like this so “believable”? Or, to put it another way, why do some stories become urban legends when others do not, and why do we accept them? Read the full story here More content:Have you seen our e-magazine, CURIOUS?
