Don’t Rely on an App to Identify Which Mushrooms You Can Eat

Mushroom hunting is a dangerous sport. The differences between deadly and delicious mushrooms can be subtle and hard to spot, and it's not a verdict that should be left up to guessing. Earlier this year, 14 people in Northern California became sick after eating foraged "death cap" mushrooms, and three had to have liver transplants.

An app called Mushroom claims to be able to identify whether a mushroom is safe or toxic through artificial intelligence. However, as The Verge reports, experts say an app isn't a foolproof way to identify mushrooms, and users could be putting themselves in danger by relying on it.

Some mushrooms need to be touched and smelled to identify whether they are a truly safe-to-eat species or if they're a similar-looking toxic variety, a mushroom expert told The Verge. And artificial intelligence working solely off images won't be able to tell the difference. As one environmental scientist put it on Twitter, the app's shortcomings could have deadly results.

In response to the uproar, the app seems to have been edited to focus just on the lucrative practice of truffle-hunting. The new app's description is a confusing liability warning: "The app is intended for the general interest truffle hunter as a reference guide who is [sic] looking to hunt and sell truffles locally. The app is not intended for use when foraging for wild food and we strongly recommend you do not handle or consume wild mushrooms." In other words, use it as a reference guide if you want to sell truffles, but don’t eat them. While truffles aren't toxic, there are species of "false truffles" that are poisonous, so probably don't rely solely on artificial intelligence for those, either.

There are several other mushroom-hunting guide apps, but they mostly regurgitate information that you would find in books on the subject. Getting an illustrated guidebook is most experts' recommended method for safely foraging for mushrooms. So please, if you want to become a mushroom hunter, ditch the apps, hire a guide, take a class, or, at the very least, buy a good book. Don't simply trust the 'bots.

The World’s First 3D-Printed Opera Set Is Coming to Rome

In October, the Opera Theater in Rome will become the first theater to play host to a 3D-printed set in one of its operas. The theater’s performance of the 19th-century opera Fra Diavolo by French composer Daniel Auber, opening on October 8, will feature set pieces printed by the Italian 3D-printing company WASP, as TREND HUNTER reports.

Set designers have been using 3D printers to make small-scale set models for years, but WASP says this seems to be the first full 3D-printed set. (The company is also building a 3D-printed town elsewhere in Italy, to give you a sense of its ambitions for its technology.)

The Fra Diavolo set consists of what looks like two warped historic buildings, which WASP likens to a Dalí painting. These buildings are made of 223 smaller pieces. It took five printers working full-time for three months to complete the job. The pieces were sent to Rome in mid-July in preparation for the opera.

Recently, 3D printing is taking over everything from housing construction to breakfast. If you can make an office building with a printer, why not a theater set? (Though it should be noted that the labor unions that represent scenic artists might disagree.)

A Simple Way to Charge Your iPhone in 5 Minutes

Spotting the “low battery” notification on your phone is usually followed by a frantic search for an outlet and further stress over the fact that you may not have time for a full charge. On iPhones, plugging your device into the wall for five minutes might result in only a modest increase of about three percent or so. But this tip from Business Insider Tech may allow you to squeeze out a little more juice.

The trick? Before charging, put your phone in Airplane Mode so that you reduce the number of energy-sucking tasks (signal searching, fielding incoming communications) your device will try and perform.

Next, take the cover off if you have one (the phone might be generating extra heat as a result). Finally, try to use an iPad adapter, which has demonstrated a faster rate of charging than the adapter that comes with your iPhone.

Do that and you’ll likely double your battery boost, from about three to six percent. It may not sound like much, but that little bit of extra juice might keep you connected until you’re able to plug it in for a full charge.
