Dissecting a black widow spider to get its silk glands seems like a task fraught with peril. Luckily, for anyone who dares, now there is video from scientists to show you how it’s done.

Before there were photocopiers, scanners and printers, there was the Ditto Machine (a.k.a. spirit duplicator), produced by the Illinois-based Ditto Corporation. Originally introduced in 1923, the Ditto Machine was a printing method that transferred ink onto a master copy made of smooth, waxy paper. An alcohol-based fluid (hence “spirit”) was then applied to transfer the image to a copy. Primarily used by schools and churches, the Ditto became less and less commonplace as other copying technologies were brought to market.

A new study out today from the Texas Transportation Institute shows that the country saw a historic dip in traffic jams in 2008 and 2009.

When Frenchman Louis Mantin died in 1905, he mandated that his house be sealed up for a century, then reopened to the public as a museum. And now it is, effectively becoming a time capsule for all to see.
The French mansion, located in the town of Moulins, is full of artifacts and pieces that Mantin had collected over the course of his life, including paintings, tapestries, prehistoric flints, Egyptian relics and other pieces from the Medieval and Neolithic eras.
