European leaders open world’s longest rail tunnel in Switzerland –
The world’s longest rail tunnel, running for 35 miles (57km) under the Swiss Alps, has officially opened. The Swiss president, Johann Schneider-Ammann, said the tunnel, which it is hoped will ease transit through the heart of the continent, would “join the people and the economies” of Europe at a time of rising nationalism and border closures. He spoke before European leaders made a ceremonial first journey through the Gotthard base tunnel. Passengers included the German chancellor, Angela Merkel, the French president, François Hollande, and the Italian prime minister, Matteo Renzi. While the tunnel was entirely funded by Switzerland, a non-EU member, the bloc’s transport commissioner, Violeta Bulc, hailed it as “a godsend” for the continent. It runs from Erstfeld in the central Swiss canton of Uri, to Bodio in the southern Ticino canton. [The Guardian]

Dagger in Tutankhamun’s tomb was made with iron from a meteorite –
A dagger entombed with King Tutankhamun was made with iron from a meteorite, a new analysis on the metal composition shows. In 1925, archaeologist Howard Carter found two daggers, one iron and one with a blade of gold, within the wrapping of the teenage king, who was mummified more than 3,300 years ago. The iron blade, which had a gold handle, rock crystal pommel and lily and jackal-decorated sheath, has puzzled researchers in the decades since Carter’s discovery: ironwork was rare in ancient Egypt, and the dagger’s metal had not rusted. Italian and Egyptian researchers analysed the metal with an x-ray fluorescence spectrometer to determine its chemical composition, and found its high nickel content, along with its levels of cobalt, “strongly suggests an extraterrestrial origin”. They compared the composition with known meteorites within 2,000km around the Red Sea coast of Egypt, and found similar levels in one meteorite. That meteorite, named Kharga, was found 150 miles (240km) west of Alexandria, at the seaport city of Mersa Matruh, which in the age of Alexander the Great – the fourth century BC – was known as Amunia.
