This video tutorial is about Android, and no it's not a robotic creature, it's a software platform and operating system form mobile phones and PDAs. The Android system is based on Linux and was developed by Google and the Open Handset Alliance. Code is managed in the Java language, but can be written in C also, although C is not officially supported. A lot of the new cell phone and other mobile devices will be running off of Android, so know how to use it.
If you're a beta tester, you know Apple released iOS 13.3 this week, bringing with it stability for multitasking as well as minor changes throughout the OS. It seems Apple doesn't want the rest of us to go without this critical patch, as the company releases iOS 13.2.2 today, Thursday, Nov. 7.
Augmented reality might not be able to cure cancer (yet), but when combined with a machine learning algorithm, it can help doctors diagnose the disease.
This demo made with Apple's ARKit is 13/10 and features a very good boy. Since the ARKit was announced, there have been rumors going around about what it could mean for pet lovers who want to see augmented reality dogs. The popular Twitter We Rate Dogs has created a Good Dogs Game app that lets you have a your own virtual dog, but now Ridgeline Labs have also entered the arena with an ARKit dog game of their own, and it's the best thing I've ever seen.
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
You will soon be able to play an AR version of one of the most frustrating mobile games of all time, thanks to Apple's ARKit.
Coronaviruses are common viruses, and most of us catch one at some point — they cause about 30% of all common colds. A new accidental discovery could help fight these viruses, even the deadlier, emerging ones.
Intense exercise can cause problems with our digestive tract. It even has a name — "Exercise-induced Gastrointestinal Syndrome." Simply put, strenuous exercise can damage the gut and let the bacteria that reside there potentially pass into the bloodstream.
For companies wary of the temperature, PTC just made it easier for them to dip their toes in the waters of augmented reality.
Phase 2 of a Zika vaccine trial began in the United States this week, along with Central and South America.
In the past, infection with human immunodeficiency virus (HIV) commonly led to dementia as the virus made its way to the brain. Even in effectively treated people, HIV can hide out and replicate in places like the brain, where it's tough to detect. That's why it's very concerning that half of all HIV-infected patients still report cognitive problems.
By looking for the mechanism that allows influenza A to invade lung cells, scientists also discovered a treatment that might block the virus from taking hold there.
As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.
Transmitted by a sandfly one-third the size of a mosquito, parasitic Leishmania protozoa are responsible for a flesh-destroying disease that kills an estimated 20,000 people per year. Two new studies offer understanding of how the parasite provides immunity through persistence and why some people suffer more virulent forms of the disease.
Lighthouses and signal fires may have been the first social media. Without the ability to share language, a distant light meant "humans here." A new study from the University of California, San Diego, finds that bacteria can also send out a universal sign to attract the attention of their own, and other bacterial species.
Video: . Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an "extraterrestrial" or "alien" (or, to avoid confusion with the legal sense of "alien," a "space alien"). These as yet hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans. The possibility that viruses might exist extraterrestrially has also been proposed.
Fasting—or the practice of regularly abstaining from ingesting anything except water—is a pretty drastic move. I tried to fast for two days and made it to the 12-hour mark, which is when I broke down and ate a quart of ice cream.
If you've seen any videos of aurora borealis, star trails, or a solar eclipse, then you're probably well familiar with time-lapse photography. Whether it's a beautiful moving landscape or a deadly natural disaster, time-lapses show us what would otherwise be hour-long recordings as short and sweet videos.
In 2006, everything that revolved around my world shattered into tiny pieces as I learned that scientists had decided to rescind Pluto's planetary status. Given the ol' Jeff Probst treatment, Pluto was officially voted off our solar system in the blink of an eye, leaving us with only eight planets and a whole load of useless textbooks. The primary reason that Pluto was demoted down to a "dwarf planet" was due to Pluto's largest moon, Charon, being about half the size of Pluto; all the other p...
The cell phone may have replaced the pocket watch, but thanks to some clever mods and hacks, "old-fashioned" time telling is making a comeback. Smart watches that connect to your mobile device cannot only tell you what time it is, but also change the song you're listening to and let you know how many Facebook notifications are waiting for you. Frank Zhao, an electrical engineering student at the University of Waterloo, decided to do something a little different with his LED pocket watch. It h...
Technology is awesome. You can use your iPad to record music or even turn your tunes into a solar system, but sometimes being plugged in all of the time can leave you nostalgic for simpler times. This new concept by Joelle Aeschlimann brings together the best of both worlds by turning your iPad into an old-fashioned, hand-cranked music box. The artist created three different music boxes, each one with its own unique song and visualization. The music boxes were made using wooden cylinders with...
Want to build your own life-sized, working replica of WALL-E? Be prepared to take on a second job! Mike Senna spent two years perfecting his own version, working 25 hours a week and totaling somewhere around 3,800 hours for the whole project. He had no blueprints to go by, so he spent a lot of time watching the movie over and over to get everything just right. The video below shows some of the construction; skip to about the one minute mark to see WALL-E in action.
For years, astronomers have been trying to figure out how our galaxy came to be. Even with the help of high-performance computers, no model of a spiral galaxy has ever been able to recreate the Milky Way, until now. An international team of researchers has created the first successful simulation of what happened 14 billion years ago to give our galaxy its unique shape. Turns out, all they needed was a bigger bang. Photo by IntelFreePress
