China launched its first freight train to London on Sunday, according to the China Railway Corporation.

The train will travel from Yiwu West Railway Station in Zhejiang Province, Eastern China to Barking, London, taking 18 days to travel over 7,400 miles.

The route runs through Kazakhstan, Russia, Belarus, Poland, Germany, Belgium and France, before arriving in London. The UK is the eighth country to be added to the China-Europe service, and London is the 15th city.

Writing in The Lancet Gastroenterology & Hepatology, scientists have officially announced the discovery of a new organ inside the human body. That’s right, there’s a brand new organ hiding in our abdomen and it’s only just been classified.

Known as the mesentery (meaning “in the middle of the intestines”, it can be found in our digestive systems. Leonardo da Vinci actually gave one of the first descriptions of it back in the day, but until around 2012 it was thought to be a series of separate structures keeping the intestines attached to the abdominal wall, like a series of support girders.

A team from the University of Limerick, however, used complex microscopy work to confirm that the structures are all interconnected and appear to be part of one overall structure. Much of the research was conducted on patients undergoing an operation to remove most or all of their colon.

Having been taught to medical students since 2012 as being a new organ, it has now been added to the famous Gray’s Anatomy textbook and described in this new paper.
