News: Living Bacteria in Clothing Could Detect When You Come in Contact with Pathogens or Dangerous Chemicals

While at work, you notice your gloves changing color, and you know immediately that you've come in contact with dangerous chemicals. Bandages on a patient signal the presence of unseen, drug-resistant microbes. These are ideas that might have once seemed futuristic but are becoming a reality as researchers move forward with technology to use living bacteria in cloth to detect pathogens, pollutants, and particulates that endanger our lives.

News: Downloads for Encrypted Messaging App Signal Have Almost Doubled Since Trump Took Office

Signal, the encrypted messaging app, has seen 1.4 million downloads in just the first quarter of 2017—roughly twice the downloads it received in the same period last year. Rani Molla at Recode attributes this to Donald Trump's inauguration, as the private messaging service saw a 40% increase in US downloads between Election Day and the end of the first quarter of 2017.

How To: Check Your iPhone for 32-Bit Apps That Won't Work in iOS 11

Apple has removed support for older 32-bit applications in the new iOS 11, which was to be expected after the 10.3 update added the ability to detect apps that are still running 32-bit processes on your iPad, iPhone, or iPod touch. Apple even excluded restore images for 32-bit devices such as the iPhone 5 and iPad (4th gen) in the iOS 10.3.2 beta 1 update for developers, so this shouldn't be a surprise.

How To: Protect Individual Apps on Android That You Can Only Unlock with Your Face

Locking individual apps on your Android device gives you an added layer of security by safeguarding app data from unwanted attention. I personally prefer using an app locker over a standard lock screen because my kids play with my phone, and they've completely disabled it after inputting the wrong PIN. So app lockers give me the right balance between giving my children access to my device, and the security of locking down my data from would-be intruders.

How To: Add a Google Photos Shortcut to Your Android's Camera App

If your Android phone was made by Samsung, LG, HTC, or any other manufacturer that likes to apply skins on top of stock Android, then your camera app is tied to the custom gallery app that was preinstalled on your device. In other words, when you tap that little image preview icon after taking a picture, you'll be taken to a camera roll interface that was made by an electronics manufacturer.

News: You Can Now Turn Pixel's 'App Shortcuts' into Their Own Home Screen Icons

One of our favorite features on the Pixel Launcher is its App Shortcuts, which work a lot like Apple's 3D Touch for iOS or Huawei's Force Touch. Instead of using pressure sensitivity to call up static and dynamic shortcut menus for apps, Launcher Shortcuts relied on a simple long-press. Now, in the Android 7.1 update for Pixels, there's an update to App Shortcuts that let's you pin shortcut options directly to your home screen for even quicker access.

How To: Change Android's Language & Locale on a Per-App Basis

Android clearly wasn't made with bilingual users in mind. When you set a default system locale, every app on your phone uses that region's language—and there's no granular control here. This really becomes an issue if you use social media or news apps that are primarily in a different language, because apps are generally written in the developer's native tongue, then poorly translated to all other languages.

How To: Make Your Own Battery-Saving 'Lite Apps' for Android

Several major web services—most notably Facebook—have horrendous Android apps that occupy way too much space and drain battery life at an alarming rate. Such issues have led to a new trend where third-party developers create minimalist "lite" apps that are essentially the mobile website bundled into a native Android wrapper, freeing up storage space and saving battery life without sacrificing many features at all.

How To: Stop Apps from Accessing Your Google Account

Many apps and services that are available for Android can only work if they have access to your Google account. While you're setting up one of these apps, you'll see a popup that says something like "This app would like to access your Google account," and the options are "Accept" or "Cancel." Of course we tap "Accept" here to ensure that the app will work properly, but what are the long-term repercussions of doing that?
