Every time you grab your phone to participate in a group chat, watch a YouTube video, or search the internet, you leave a digital footprint of your activity. This trail can compromise your privacy the next time a friend borrows your device. It also puts your personal information at risk should your phone fall into really unscrupulous hands. In this guide, we’ll explain how you can prevent your device from logging and storing data where other people can easily stumble across it....

Indian food is my everyday food. Dal, rice, and sabzi are the staples my mom used to make for our family when she came home from busy days at work and had to put dinner on the table in 20 minutes. These are the dishes that I cook when I come back from vacation and need to reset. In the U.S., Indian cooking is often misunderstood to be complicated, time-consuming, and overly heavy....

Once they’ve demonstrated their mastery of the challenges, and signed contracts vowing to never use their skills for evil, the guards graduate. If they choose, they can seek Ethical Bank Robbing certificates, or can hop right in to a career in security. That’s essentially how many young hackers (the friendly kind) are trained today. The first step for students, before moving into a government or Big Business job where they work to prevent hacks, is to learn the darker side of the trade: exploiting loopholes, thieving from servers, cracking passwords–and not just learning those techniques but actually performing them, in a classroom set up especially for the experience....

1 Take three barf bags from nearby seat pockets, and remove their pliable closure tabs. 2 Bend two tabs into Z shapes. Work one end of each tab into gaps above the tray table lock. The other ends cradle the bottom of your phone. 3 Fashion the third tab into an inverted J, and wedge it between the lock and the upholstered seat to secure the top of the phone....

But, there may be a reason why, as a species, humans are late bloomers. A new study published today in the journal Science Advances finds that the ability to to forage for difficult-to-extract resources increases slowly over the course of a human childhood. Because foraging as a human is a tricky task, we need plenty of time to learn how to do it. “Early human life history is quite unique, in the sense that childhood, as a period loosely delimited by weaning and the onset of the physiological and social changes that lead to maturation, is a period of life unique to humans,” lead author of the study Ilaria Pretelli, told Popular Science....

“The damages that we are seeing are catastrophic,” said Governor Pedro Pierluisi via The Associated Press. Just after 2 p.m., before the storm even made landfall, power was out for the entire island. About 1.3 million residents were impacted. Power restored for about 100,000 overnight according to LUMA Energy, Puerto Rico’s main power supplier. LUMA warned that full power restoration in Puerto Rico could take several days, with the storm creating “incredibly challenging” conditions for repair workers....

The technique of freeze-drying is not limited to the food-service industry. In fact, commercial freeze-drying was developed during World War II. It was used to preserve blood plasma and medications like penicillin without the need for refrigeration. Freeze-dried coffee was invented by Nescafe in 1938 in order to help deal with surpluses of coffee in Brazil. Today you can purchase a wide variety of freeze-dried food products in the marketplace, ranging from fruits and vegetables to entire freeze-dried meals from lasagna with meat sauce to Jamaican-style chicken and rice....

As International Business Times wrote: The holiday timing of the delivery, as well as its relatively innocuous contents, adds a charming twist to a growing threat: cheap drones used to bring contraband into prisons. In the United States, the Justice Department stated it wants to find a way to keep drones out of the prisons it controls, and people have already used drones stateside to get contraband into prisons. While the United Kingdom deals with a rash of drone smugglers, they might want to turn to Tokyo for advice....

The feature, called Sensitive Content Control, lets users choose if they want to see more or less “sensitive content” from people or accounts that they do not follow. “You can think of sensitive content as posts that don’t necessarily break our rules, but could potentially be upsetting to some people — such as posts that may be sexually suggestive or violent,” Instagram says in their press release. “Because we show you posts from people you don’t follow on Explore, we try not to show content that some may find sensitive,” the company elaborated on Twitter following the announcement....

Surprisingly, players challenged calls from the other side of the court an equal amount, and both players and linesman were less accurate calling balls on the baseline and service line than on the sidelines or center line. Players who challenged less weren’t found to be more or less accurate than their counterparts, so don’t go home with a challenge in your pocket. Hawk-Eye is a camera-based system that got its start in cricket....

The iPhone 7 release date is, at the moment, unknown as are the details surrounding what Apple’s new flagship phone may contain. But a series of recent reports that began in November 2015 suggest that Apple could be moving to eliminate the 3.5mm headphone jack on the iPhone 7 entirely, instead relying on the existing Lightning charging port to also carry audio (the Lightning standard allows for this today on current-gen iPhones), as well as wireless headphones....

Here’s how DARPA describes their MAgnetoHydrodynamic Explosive Munition (MAHEM) railgun: Essentially, the weapon will use electricity to bend metal into the specific deadly form needed as it’s fired. If built, a person firing the weapon could adapt their attacks if the vehicle they’re attacking survived one type of shot. Beyond that, details of the weapon in American publications are sparse, but David Hambling at Popular Mechanics appears to have found a paper by Chinese researchers that details a very similar weapon....

Researchers from Sweden looked at power weightlifters that had stopped using anabolic steroids years before. The study found that while the drugs could no longer be detected, a physiological difference still existed that could benefit the athletes. The study analyzed three groups of lifters: previous users who hadn’t used in years, current lifters who had never used, and current lifters who were still using. Muscle fiber distribution, fiber area, and a handful of other biological indicators were tested in the vastus lateralis muscle (quadriceps) and the trapezius muscle....

Popular Science: Where did your interest in science come from? J.J. Abrams: My grandfather was a huge inspiration. He was the owner of an electronics company, and after World War II he sold surplus radio and electronics kits to schools. We would spend hours building and soldering things. As a young kid, it’s so inspirational to see that you can build things that aren’t made by the hand of God, that you can attach the motor to a wire and make something work....

William Myers’ new book, Bio Design: Nature + Science + Creativity, imagines a world where grass is grown into benches, bacteria is wearable clothing and animals can help their owners breathe. Highlighting collaboration between designers and biologists, it’s a collection of the most innovative ideas biodesign — design that incorporates living materials — has to offer. Click here to enter the gallery Fusing natural organisms with human innovation, these designs — some of them far-fetched concepts, some prototypes and some completed projects — re-imagine our relationship with the natural world....

To better understand how these violent storms work, researchers have combined data from a number of imaging systems: Juno, which has been orbiting Jupiter since 2011, the Hubble Space Telescope, which just celebrated its 30th birthday in orbit, and the Gemini observatory, a pair of telescopes that sit atop mountains in Hawaii and Chile. Together, these three technological beasts have allowed scientists to understand and image Jupiter’s weather in more detail than ever before....

In a statement on Thursday, Juul cited two studies released this week in the Journal of the American Medical Association showing just how popular e-cigs have gotten among kids and adolescents. One of the studies estimates 2.4 million teenagers now use flavored e-cigarettes, including nearly 30 percent of all high-schoolers. Juul is by far the most popular brand, and as the other study shows, mint is the flavor of choice among its high-school customers (and a close second for 8th-graders)....

But these powders, seeds, roots, and fruits have to start somewhere—and their plants of origin can be unrecognizable. Here are ten of the most surprising seasoning shrubs. Saffron As the red stigma of a purple flower that turns dishes yellow, saffron always keeps you guessing. One of the most expensive and precious spices in the world, it’s believed to have been initially cultivated in Greece, though today it’s also grown in the Middle East and India....

The trend exists worldwide, paralleling the increasing intensity and frequency of marine heat waves. Even if we could stop our greenhouse gas emissions today, corals would face a precarious future, in which a jump in temperature of just a couple degrees could destroy vast numbers of these creatures. That’s why some marine biologists are looking for ways to buy these organisms some time. And one way to do that might be to enhance their symbiotic algae, as a new study in Science Advances finds....
