A new species of giant rhino has been unearthed in north-western China. A completely preserved skull and jawbone was found in the Linxia Basin of Gansu Province, where people have been looking for mammal fossils since the 1980s. The giant rhino had a long neck, slender skull, and two cone-shaped upper first incisors. It would have looked more like a horse than a rhino, but with a head height of 7 meters. The rhino is estimated to have weighed about 21 tonnes.

Tech in Argentina has always been inaccessible due to the country's traditionally protectionist policies. Even when the government decided to distribute free netbooks to students, it was under the condition that the netbooks be made in Argentina. More than four million students received a computer between 2011 and 2015. The netbooks brought a new generation of artists to the spotlight. While the netbooks weren't particularly powerful, they opened up a world of creative ability for young artists. The netbook program was slated to end in 2018, but it has continued to run under a new government.

The IRON stablecoin was partially collateralized with USDC, with the rest coming from TITAN, a volatile asset. If the price of IRON fell below $1, arbitrage traders could buy it and then redeem it with the IRON treasury for $0.75 USDC and $0.25 worth of TITAN. This caused traders to dump IRON and collect risk-free profit, which then devalued TITAN to nothing. The smart contract that holds the USDC to be redeemed requires the price of TITAN to be above zero for it to be unlocked, so now all the coins are stuck. This could have been easily prevented with a code audit.
