Google Made a Major Change to Its Privacy Policy—Here’s How to Opt Out

Over the summer, Google abandoned a policy that had set them apart from other big sites like Facebook and Twitter. The search giant once vowed to make privacy a priority, keeping identifiable information gathered from Gmail separate from the web-browsing data used by advertisers. But as of June 28, that distinction is no longer in place by default. According to the update, user activity “on other sites and apps may be associated with your personal information in order to improve Google’s services and the ads delivered by Google.”

This change was widely glossed over when it first was made, but ProPublica recently took a closer look. If you were an existing user at the time of the move, you would have received an opt-in request titled something along the lines of “Some new features for your Google account.” Anyone who has signed up for an account since then would have been opted in by default.

In the past, the customized DoubleClick ads that popped up around the web were only based on users’ Google searches—but now they can reference keywords mined from Gmail as well. It’s easy to see how this might raise privacy concerns for some users, especially those who weren’t aware of the switch. To see if you’re affected, go to the Activity Controls section on Google’s My Account page. If the box that reads “Include Chrome browsing history and activity from websites and apps that use Google services” is unchecked, you’re in the clear.

Unfortunately, Google is just one of the sites doing questionable things with your personal information. To see how much Facebook knows about you, you can download this Chrome plug-in.

Watch Tesla’s Fully-Autonomous Vehicle in Action

Tesla Motors recently made a groundbreaking announcement: From this point forward every car from the automaker will have the hardware necessary for self-driving capabilities, TechCrunch reports. That includes cameras and sensors that will allow vehicles to navigate themselves with zero driver assistance.

For now, the autonomous driving software meant to go along with it still isn’t ready for consumers. But after more tests are completed, the company plans to demonstrate the new technology with a cross-country road trip at the end of 2017.

For a peek at what that might look like, Tesla released a four-minute video of one of their vehicles navigating a city commute on its own.

After sharing the clip on Twitter, CEO Elon Musk announced a few special features that could help Tesla stand out from other companies looking to break into the autonomous vehicle market. According to Musk, the car is able to “read” signs so it knows where not to park. He also described a feature that would allow car owners to summon their vehicles from their smartphones, even from the other side of the country. That may sound like science fiction to today’s motorists, but experts predict that an autonomously-driven reality is just a few years away.

Scrotum Frogs Near Lake Titicaca Die Off in Alarming Numbers

Telmatobius culeus, Lake Titicaca Water Frog (captive), IUCN Redlist: Critically Endangered, Balsa de los Sapos, Pontificia Universidad Catolica del Ecuador, Quito, Ecuador

 
An odd-looking frog with a funny name is currently facing a very serious threat. As National Geographic reports, Titicaca water frogs (Telmatobius coleus), also known as scrotum frogs, are turning up dead by the thousands in South America, and scientists are still unsure why.

The species, which can be found around Lake Titicaca on the border of Peru and Bolivia, was in a dire situation to begin with. Populations have plummeted by 80 percent in recent years, and this latest mass death has placed added stress on the critically endangered amphibian.

Roughly 10,000 of the frogs were found dead along a 30-mile stretch of the Coata River branching out from Lake Titicaca. Water tests and necropsies will hopefully shed more light on the cause, but scientists are already pointing fingers at pollution. Human sewage and heavy metal runoff from mining are both possible factors at play.

The scrotum frog is aptly named for its wrinkly, baggy skin. In addition to creating a distinct look, the extra skin folds allow the frogs to absorb more oxygen underwater in the high altitudes of the Andes. The name has also led to an unfortunate (and false) association with virility: Those seeking health benefits will sometimes harvest frogs from the lake and turn them into medicinal broths known locally as “frog juice” or jugo de rana.

Scientists say it’s possible that these human-made stresses are compounding threats from nature. Chytrid, a disease responsible for the deaths of millions of amphibians around the globe, is another potential menace experts are considering.

6 Classic Séance Tricks Explained

filed under: History, magic

Today self-proclaimed psychics tend to get a bad rap, but during the late 19th and early 20th centuries they enjoyed celebrity status. Whether the medium performed at home or on stage, the chance to see them summon disembodied hands, decipher otherworldly messages, and belch up ectoplasm was considered quality entertainment back in the day. These so-called communions with the dead have since generally been debunked as clever parlor tricks (thanks to skeptics like Harry Houdini). But knowing the behind-the-scenes secrets of séances doesn’t make them sound any less entertaining.

1. SPIRIT RAPPING

The famous Fox sisters had spirit rapping to thank for their careers. After their mother heard mysterious knocks coming from the walls and furniture of their home, she concluded the noise was metaphysical in nature. The Fox girls were indeed responsible for the rapping, but the source was actually apples they had tied with string and bounced against the floor of their bedroom.

The sisters used this concept as the basis for their medium act. During séances, they would recite the alphabet and pretend to wait for spirits to slowly spell out messages. The “ghosts” they corresponded with weren’t really ghosts at all, nor were they apples. Rather, the girls produced the sounds themselves by manipulating the joints in their knuckles and toes.

After relying on the trick for decades, one of the sisters decided to reveal her fraud to a live audience by banging her bare toe against a wooden stool to show them how it was done. The New York Herald wrote, “There stood a black-robed, sharp-faced widow working her big toe and solemnly declaring that it was in this way she created the excitement that has driven so many persons to suicide or insanity. One moment it was ludicrous, the next it was weird.”

2. MANIFESTATION CABINETS

After first appearing on the séance scene in the 1850s, manifestation cabinets, or spirit cabinets, soon became a staple of the genre. Mediums would enter the cabinets (often curtained-off sections of stage) with their hands bound to prevent them from faking any paranormal activity. To gain the full trust of the audience, they sometimes invited spectators to come on stage and tie the ropes to their liking. Once the curtains were drawn and the lights were extinguished, all sorts of spooky mayhem took place. Hands poked out from between the drapes, ghostly figures materialized, and instruments left on the floor of the cabinet started to play themselves. At the end of the scene the curtains parted to reveal the medium tied up just as they were left.

This was a convincing trick in its time, and all it required was a little escape artistry to pull off. The medium would slip their bonds as soon as they were out of sight, freeing their hands to stand in for the rambunctious spirits. Meanwhile, accomplices would wait for the lights to go out to slip in through trap doors elsewhere on stage. As long as the ropes were refastened before the trick’s conclusion, the audience was never the wiser.

3. SPIRIT SLATES

As an alternative to the tedious task of spelling out messages one letter at a time via ouija board, mediums often used slates that spirits could supposedly write on themselves. Séance participants were given a pair of black slates and told to jot down their messages to the deceased on a slip of paper that was then sandwiched between the boards. Once the slabs were bound together, the medium would hold them to the sitter’s head, shoulder, or perhaps hang them from the chandelier for a few moments while waiting for the spirit convey their thoughts. After finally separating the slates, a mystical message would be revealed inside.

There were a few ways for mediums to pull off this sham, one of which involved a strategically placed square of cardboard. A black sheet cut to the exact size and shape of the slate would be laid inside the frame, hiding the pre-written message beneath it. When it came time to take apart the two slates the medium lifted up the prepared cardboard off the top and left the flap to cover the blank slate on the bottom. The extra slate was quickly brushed away, with the note from the great beyond providing a convenient distraction.

4. ECTOPLASM

On occasion, lucky séance participants were treated to the sight of ectoplasm oozing from their mediums. The gauzy substance was said to be part of the supernatural veil separating the spiritual realm from the physical one. The trick required near-darkness or else, according to mediums, the ectoplasm would disintegrate. Once the conduit reached a trance-like state, various orifices would secrete the material, signaling a breach between worlds.

One of the mediums best known for this phenomenon was Marthe Beraud (also known as Eva C. and Eva Carrière). Instead of extruding ghostly goo through her mouth, nose, and ears, she stuffed them with muslin or a similar fabric. She sometimes added photos clipped out from newspapers to give the ectoplasm a bit of personality. This signature touch ended up being her downfall: The faces she used (which included those of actress Mona Delza, King Ferdinand of Bulgaria, and Woodrow Wilson) were eventually recognized, exposing her deception.

5. SPIRIT TRUMPETS

One of the most unusual accessories to come out of the spiritualism craze was the spirit trumpet. Without context, the instrument more closely resembles a cheap telescope than a tool for communicating with the dead. Such contraptions were believed to amplify the whispers of spirits and could produce sounds when the medium was nowhere near it. Of course the medium was behind every murmur: A rubber hose connecting the trumpet on stage to a manifestation cabinet could be threaded beneath the carpet, allowing the out-of-sight psychic to provide the vocals. More outrageous accounts of trumpets floating “around the room in a bright light, tapping the sitters on the head, talking and going through a whole lot of strange maneuvers without any assistance from mortals,” have been spread in the past. In the 1903 book Mysteries of the Séance and Tricks and Traps of Bogus Mediums, the author advises readers who’ve heard of such scenes to “sprinkle a little salt on the tale before you swallow it.”

6. FIRE TESTS

Mediums would sometimes subject themselves to a series of trials to prove their connection to their spiritual realm. One especially convincing trick was the fire test: The mediums in question boasted that a special power given to them by the spirits made them impervious to heat. They backed up this claim by holding hot coals, waving their hands through flames, and performing other feats of pain endurance. The reason they were able to pull this off without screaming in agony boils down to chemistry. A mixture of a few basic components—namely camphor gum, whiskey, quicksilver, and liquid storax—could be used to create a fireproof glove of sorts. But no matter how desperate you are to take your séance to the next level, this is one trick we don’t recommend trying at home.

Meet the Librarians Who Act as the New York Public Library’s Human Google

filed under: libraries

Before the age of smartphones, anyone with a burning question either had to keep it to themselves or head to the library for an answer. The New York Public Library opened their “Ask NYPL” hotline for curious callers to pose their inquiries to a live librarian in 1967. Nearly five decades later, the service still handles over 30,000 calls a year. Great Big Story recently highlighted a few of the men and women who continue to act as human search engines for people who either don’t have access to technology or “just want somebody to talk to.” After watching the video above, you can check out even more odd questions the library has received over the years.

Tips for Scoring a Satisfying In-Flight Meal

In-flight meals rank up there with gabby neighbors and cramped legroom as one of the least enjoyable aspects of air travel. But on long flights, a soggy, pre-prepared dinner is often a necessary evil. Bloomberg recently shared a few tips for eating well on an airplane if flyers don’t feel like packing food from home.

To make the most of the next dish you’re served in-air, Inflight Feed founder Nikos Loukas told Bloomberg he recommends sitting as close to the front of the plane as possible. First and business class passengers obviously eat better than those seated in the back (they have a different menu), but the principle applies within economy as well. Because flight attendants usually take orders from front to back, seats closer to the front tend to get served the best-looking food. Less-appealing plates may be skipped over before finally reaching the customers seated in the very back.

Other tips for receiving the most satisfying meal possible include ordering meats served in sauces (bold, spicy flavors hold up well against the effects of flying on your taste buds) and asking for an upgrade. According to Loukas, flight attendants have been known to serve business class meals to economy passengers who ask for something better.

If you’re still unable to boost your food quality after going through all that trouble, consider supplementing your sorry meal with an in-flight cocktail. Delta’s director of on-board services Brian Berry recently told Business Insider that the simplest cocktails are the best choices for in-flight boozing. With limited time and space for flight attendants to practice mixology, drinks with long ingredient lists tend to suffer in quality. Berry recommends ordering a drink of no more than three ingredients. A can of bloody Mary mix or tomato juice with some vodka—a scientifically proven great drink to enjoy at 30,000 feet—is a good place to start.

British Phone Booth Transformed Into ‘World’s Smallest Museum’

It doesn’t take long for guests to explore the contents of the newly-opened Warley Museum in West Yorkshire, England. That’s because the museum, which formerly served as a telephone booth, only has room to accommodate one visitor at a time.

As The Telegraph reports, the museum started as a passion project for the Warley Community Association (WCA). The WCA assumed the booth from British Telecommunications after the company decided to pull the plug on 43 phone booths in the area.

Instead of repurposing the space into a salad shop or a tiny office, the town decided to make it into a museum dedicated to local history. Today the phone box is filled with items like photographs, antique jewelry, and glass etchings, which anyone can stop in to admire. Every three months, the artifacts will be switched out to fit a new theme.

The museum claims to be the world’s smallest, but the WCA is still waiting to hear back from the Guinness World Records committee for the official designation. Other institutions that have brandished the title include a 134-square-foot shed in Superior, Arizona and an old freight-elevator shaft in New York City.

Tasmanian Devil Milk Could Help Fight Drug-Resistant Bacteria

As more people use antibiotics to fight infections, certain strains of bacteria are becoming harder to beat. A future tool in the fight against drug-resistant superbugs may come from an unusual source: Tasmanian devil milk. As Gizmodo reports, milk from the marsupials contains certain chemical compounds that can wipe out most dangerous bacterial infections.

For their research, recently published in Scientific Reports, scientists from the University of Sydney analyzed Tasmanian devil milk in their search for new superbug-fighting compounds. Milk from marsupials like Tasmanian devils differs from that of other mammals in that it has to provide nourishment to an underdeveloped infant. Joeys enter the pouch after a little more than a month of gestation, and their mother’s milk offers them extra immune support once they leave the safety of the womb.

The research team was able to pin down the compounds responsible for this special property. Tasmanian devil’s milk contains six antimicrobial peptides called cathelicidins. For comparison, humans have just one. After synthesizing the compounds in the lab, researchers found them to be effective against potentially deadly bacteria such as vancomycin-resistant Enterococcus faecalis and methicillin-resistant Staphylococcus aureus, or golden staph.

Antibiotic-resistant superbugs are one of the biggest health threats we’re currently facing. Tasmanian devils aren’t the only marsupials that might prove useful in the battle against them: Wallabies and opossums boast exceptionally high numbers of antimicrobial compounds as well. Study researcher Emma Peel told the BBC that studies into koala milk are also underway.

Airbnb Is Offering Two Guests a Stay in Dracula’s Castle on Halloween Night

Image credit:

If flickering candles, squeaky staircases, and coffin beds fit your description of a cozy vacation home, Airbnb has the perfect listing for you. As The Telegraph reports, the lodging service is inviting two guests to stay at Bran Castle, or “Dracula’s Castle,” on the night of October 31.

Though Dracula author Bram Stoker never visited the location in person, it’s believed to have been one of the primary inspirations for the castle featured in his famous novel. He described his fictional fortress as sitting “on the very edge of a terrible precipice”—a striking parallel to the real-life building in the Carpathian mountains of Transylvania, Romania.

According to the Airbnb listing, guests will arrive at the castle in a horse-drawn carriage at sunset. The description reads: “The chill that suddenly fills the carriage is not the evening mist, it’s a fear older than the forests now grown up around the castle rock. This is the lair of vampires, and you cannot leave until dawn.”

From there, visitors will be welcomed in by their host for the night, Dacre Stoker, the great grandnephew of Bram and a “vampire expert.” After dining on a “blood-enriching” dinner, guests will retire to the Count’s crypt for a good night’s sleep in velvet-lined coffin beds.

Dracula’s castle does enforce a few house rules: Garlic-scented items are banned, mirror-selfies are frowned upon, and crossing cutlery or “placing anything in a cross formation” is prohibited. Anyone who can agree to adhere to those conditions can enter to win their stay through Airbnb. As was the case with the one-night stay in the Paris catacombs offered through the site last Halloween, guests will be chosen based on their response to an essay question. This year’s prompt: Explain what you would say to Count Dracula if you were to meet him in his castle.

High-Tech Paper Rolls Up Into a Functioning Torch

Takeo has been producing fine paper in Japan since it was established in 1899, but the manufacturer recently embarked on a project that veered away from its traditional roots: As engadget reports, the company teamed up with the printable circuits start-up AgIC to create a sheet of paper that doubles as an adjustable flashlight.

The Paper Torch is the most recent capsule collection from the product development platform Design of Things. The project uses printed circuits to achieve the simple and unique design. When the sheet is rolled up the circuits appear to react, creating shortcuts and delivering more power to the light bulb. The amount of light dispersed varies based on how tightly the torch is rolled.

Printed circuits have been used to create paper-thin lights in the past: In July we highlighted a bookmark produced by another Japanese design firm that transforms into a reading light when bent. The Paper Torch looks like it produces a lot more illuminating power, but consumers will have to wait a while before getting their hands on one. A crowdfunding campaign for the concept is set to launch in Japan in mid-November.
