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: World Malaria Day Reminds Us That The Fight Isn't Over

The theme for 2017's World Malaria Day, which is today, April 25, is "End Malaria for Good." For many Americans, this might seem like an odd plea. Especially since Malaria is seemingly an obsolete problem here. However, on World Malaria Day, it's important to remember the danger of malaria is still very much present in the US. And around the world, the disease is at the epicenter of a global crisis.

News: The Latest in HIV Prevention — Syringe Vending Machines in Vegas & On-Site Testing at Walgreens

It's about time people acknowledged that judging drug users would do nothing productive to help them.

News: Compound in a Frog's Defensive Slime May Treat Your Next Flu Infection

Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.

News: Frustrated by Acne? New Research Shows Skin Microbiome Makes a Difference

The squiggly guys in this article's cover image are Propionibacterium acnes. These bacteria live in low-oxygen conditions at the base of hair follicles all over your body. They mind their own business, eating cellular debris and sebum, the oily stuff secreted by sebaceous glands that help keep things moisturized. Everybody has P. acnes bacteria—which are commonly blamed for causing acne—but researchers took a bigger view and discovered P. acnes may also play a part in keeping your skin clear.

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: Secure Your Instagram Account by Adding 2-Factor Authentication & Managing Privacy Settings

The photo-centric Instagram app is a great way to share "evergreen" pictures and videos when compared to Snapchat and Facebook's new Messenger Day feature. But like all social media, keeping the account secure is an essential aspect, as it restricts unwanted viewers from seeing your content and can prevent unauthorized users from accessing your account. Instagram has several methods for locking down the account including a new two-factor authentication (2FA) mechanism.

News: Scientists Discover How to Track Down HIV's Hiding Spots—A Potential Pathway to a Cure

Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.

How To: Fix 'Wrong PIN' Errors After Restoring a NANDroid Backup

Making a NANDroid backup can save you from all sorts of flashing-related mishaps and accidents. Bootloops, SystemUI crashes, accidental wipes, bad ZIPs, or a dozen other possibilities—there's almost no condition in which a NANDroid is unable to correct problems with your device. However, recent changes to Android have created an almost paradoxical situation where restoring a NANDroid can actually lock you out of your phone.

How To: Punchabunch Just Made SSH Local Forwarding Stupid Easy

SSH local forwarding is a must for covering your tracks and getting out there to do your work. Also called SSH tunneling, this process will put one or more steps between your machine and the machine you're working on, for security and other purposes. It can be a bit daunting for newbies to get down, and that's where Punchabunch comes in.

How To: Stop Sites from Tracking You on Your iPhone with Firefox Focus

When you do an internet search, you'll see ads that are relevant to your query mixed in with the rest of your results. Nothing surprising there—it's how the internet is funded. But then, when you click one of the search results, you'll also see ads that are related to your initial search. Now that's a bit creepy, because it demonstrates that one webpage knows what you typed into a different webpage.

How To: Activate Your iPhone's Hidden Magnifying Glass for Extreme Zooming

When you want to see something far away with a little more clarity or you're having a hard time reading small letters right in front of you, you can point your iPhone's camera at the subject and "pinch" to zoom for a better look. But there's actually something built into iOS for the exact purpose of magnifying objects, and it goes above and beyond the normal camera features.

How To: Install Android 7.0 Nougat on Your Nexus Right Now

Android 7.0 Nougat has finally arrived—well, technically, it's in the process of arriving on Nexus devices across the globe. Google uses a staged rollout system to prevent excessive server load when issuing Android updates, which means even though Nougat has made its official debut already, you might not get that "Update available" notification for another few weeks.
