What Did People Use to Mask Surgical Pain Before Modern Anesthesia?

Other than ingesting alcohol and narcotics in sufficient doses to induce a state of analgesia, for most of its history, people in the West got through surgery with the aid of little more than forcible restraint and grit. Read more…

TripAdvisor Fined In Italy For Fake Reviews

mpicpp writes with news that TripAdvisor, a travel website filled with user-generated reviews, has been hit with a €500, 000 ($611, 000) fine for “misleading customers” by failing to cull fake reviews from their list. “The regulator complained that people reading TripAdvisor Italy were unable to distinguish between genuine and fake reviews posted on the site. It said both were presented by TripAdvisor as ‘authentic and genuine in nature.’ Demanding payment of the fine within 30 days, the ICA also accused the travel company of failing to provide proper checks to weed out bogus postings.” Read more of this story at Slashdot.

Hasenkopf’s ‘Frescata’ Material-Processing Technology Yields Beautiful and Unique Surfaces

One of the cooler materials we saw at Holz-Handwerk wasn’t really a material at all, but a process. German industrial manufacturer Hasenkopf’s booth drew a steady stream of visitors all reaching out to touch the weird-looking totems, like the one above, that they had on display; I eagerly checked the product tag to find it was nothing more than Corian. So what gives? Hasenkopf was showing off their bag of new material-processing tricks called Frescata , whereby they hit Corian, Parapan, and even wood with four different bits in a five-axis CNC mill to create the intricate patterns you see here.

The Battle of the Tooth Worm

I come across a lot of strange objects in my research: books bound in human skin , prosthetic noses made of silver , iron coffins with safety devices to prevent premature burial. But perhaps one of the strangest objects I’ve seen is the one pictured on the left. This is a depiction of the infamous tooth worm believed by many people in the past to bore holes in human teeth and cause toothaches.  But before I tell you about this fascinating piece of art, let me give you a quick lesson in dental folklore. Tooth worms have a long history, first appearing in a Sumerian text around 5,000 BC. References to tooth worms can be found in China, Egypt and India long before the belief finally takes root (pun intended) into Western Europe in the 8th century. [1] Treatment of tooth worms varied depending on the severity of the patient’s pain. Often, practitioners would try to ‘smoke’ the worm out by heating a mixture of beeswax and henbane seed on a piece of iron and directing the fumes into the cavity with a funnel. Afterwards, the hole was filled with powered henbane seed and gum mastic.  This may have provided temporary relief given the fact that henbane is a mild narcotic. Many times, though, the achy tooth had to be removed altogether. Some tooth-pullers mistook nerves for tooth worms, and extracted both the tooth and the nerve in what was certainly an extremely painful procedure in a period before anaesthetics. [2] The tooth worm came under attack in the 18 th century when Pierre Fauchard—known today as the father of modern dentistry—posited that tooth decay was linked to sugar consumption and not little creatures burrowing inside the tooth. In the 1890s, W.D. Miller took this idea a step further, and discovered through a series of experiments that bacteria living inside the mouth produced acids that dissolved tooth enamel when in the presence of fermentable carbohydrates. Despite these discoveries, many people continued to believe in the existence of tooth worms even into the 20 th century. The piece of art at the top of the article is titled ‘The Tooth Worm as Hell’s Demon.’ It was created in the 18 th century by an unknown artist, and is carved from ivory. It is an incredibly intricate piece when you consider it only stands a little over 4 inches tall. The two halves open up to reveal a scene about the infernal torments of a toothache depicted as a battle with the tooth worm, complete with mini skulls, hellfire, and naked humans wielding clubs. It is, without a doubt, one of the strangest objects I’ve come across in my research; and today, I pass this random bit of trivia on to you in the hopes that you may use it someday to revive a dying conversation at a cocktail party. 1.

This Helmet Gives Eurofighters X-Ray Vision

In conventional combat aircraft, the target generally needs to be in both the pilot’s field of vision and within the sights of the plane itself. That is, the plane needed to be pointed in the general direction of whatever you’re shooting at. But in the case of the new Eurofighter Typhoon, pilots can squeeze off a few Sidewinders at bogies incoming from any direction thanks to a super helmet that links their eyes to the plane’s electronic brain.

Twitter Sued For $50M For Refusing To Identify Anti-Semitic Users

redletterdave writes “After a French civil court ruled on Jan. 24 that Twitter must identify anyone who broke France’s hate speech laws, Twitter has since refused to identify the users behind a handful of hateful and anti-Semitic messages, resulting in a $50 million lawsuit. Twitter argues it only needs to comply with U.S. laws and is thus protected by the full scope of the First Amendment and its free speech privileges, but France believes its Internet users should be subject to the country’s tighter laws against racist and hateful forms of expression.” Read more of this story at Slashdot.
