China has finally touched down where nobody has gone before: the mysterious far side of the moon. Unlike previous uncrewed missions, which largely relied on luck for a safe landing, the Chang'e 4 lander and rover made it to the lunar surface with the help of some impressive technology. David Rothery explains the science behind the mission and discusses what to expect next.

Some 4,300 years ago, a mysterious man known as Sargon of Akkad conquered a series of city states in Mesopotamia and founded the world’s first empire. But just a century or so later, Akkadia collapsed, kicking off a wave of conflict and mass migration. Now, scientists say they have evidence that the unrest was caused by a severe drought – and the evidence is found in cave stalagmites hundreds of miles away in Iran. Vasile Ersek explains.

After media coverage of a “migration crisis” in the English Channel over the holidays, Bobby Duffy argues this was another example of rhetoric running way ahead of reality. He outlines the many misperceptions Britons hold about migration – and why it’s now up to politicians to tell the truth.
