5,000 mysterious holes carved into a Peruvian hillside were an ‘ancient computer’ used for accounting

For nearly a century, thousands of strange holes carved into a barren Peruvian hillside puzzled archaeologists, historians, and even conspiracy theorists. Stretching across the dry slopes of the Pisco Valley in southern Peru, the massive formation contains more than 5,000 carefully arranged pits that can only truly be appreciated from the air. Some believed they…

In 1985, three chemists spotted an unexpected soccer-ball molecule that reshaped nanotechnology

The Chemists were vapourising carbon and noticed a perfect 60-atom cage. Image credit – Gemini While conducting experiments on the vaporisation of carbon atoms in 1985, chemists Harold Kroto, Robert Curl, and Richard Smalley obtained surprising results that showed the stability of a cluster comprising only 60 carbon atoms. This molecular structure became famous by…

Scientists have created a steel sphere device that could help buildings survive earthquakes without electricity

Earthquake-resistant technology may soon become simpler, cheaper and far more reliable thanks to a newly patented steel sphere cylinder developed by researchers at the University of Sharjah. The passive seismic damping device, created by civil engineering professor Moussa Leblouba, uses friction generated by steel balls inside a hollow cylinder to absorb earthquake vibrations in buildings,…

In 1982, a metal revealed a 10-fold structure scientists thought was impossible and ended up rewriting crystal science

Dan Shechtman found a forbidden pattern while looking at an aluminium alloy through an electron microscope. Image credit – Wikimedia When Dan Shechtman analysed the aluminium-manganese alloy rapidly cooled in April 1982 through a transmission electron microscope, the materials scientist found something unusual. The diffraction pattern on the metal revealed the tenfold symmetry, a structure…
