Well, first things firsts, it's been awhile! I'm sorry the series has been dead for a little bit, but I recently hit some personal relationship issues and needed to take some time to think. But, now that it's all said and done, the dust can settle and we can start training again!
I was a vegetarian from age 6 until age 23. When I started eating meat again for the first time in 17 years, most people I knew (including me) expected me to be pretty conservative about it: chicken breasts, hot dogs, and all the other "basic" meats that everyone loves.
Like Costco's price codes or the tags on your bread, the numerical codes printed on those sticky little fruit and vegetable labels can reveal a lot of information to us consumers. Once you understand the codes, you can look at that little label (also known as PLU, or "price look up" label) and know whether the produce you're about to buy or eat was treated with pesticides, genetically modified, both, or neither. Before we go any further with deciphering the codes on these labels, let's take a...

When Kaci Hickox, a Doctors Without Borders nurse, returned to New Jersey from working with Ebola patients in West Africa in 2014, she was surprised by her reception. Instead of a quiet return to her home in Maine after four weeks on the front line of Ebola treatment, she was quarantined by the State of New Jersey in Newark. She later filed a lawsuit in U.S. District Court for violation of her civil rights, false imprisonment, and invasion of privacy.
When the HoloStudy Demo app for HoloLens came out in September, it was a pretty impressive start to what could be a very valuable science tool for education. Now, Moscow-based HoloGroup, makers of HoloStudy, started an Indiegogo campaign to improve their modular teaching app.
With Passover soon upon us, many Jews are dreading a week (or eight days for Conservative and Orthodox Jews) of making matzo, the staple of their diet. Matzo is also known as "the bread of affliction," and I'm pretty sure it's because by day three or so you're convinced that matzo is the 11th plague.
If you're anything like me, you started down the Android-modding path for two distinct reasons; to run cutting-edge software and squeeze every bit of performance out of your hardware. Utilizing the new F2FS file system on your rooted Nexus 4 or 5 fulfills both of those desires at the same time.
While landing a job isn't the easiest thing in the world, you can probably blame your résumé for a number of lost opportunities. Writing up a cover letter and résumé is frustrating and time-consuming, but if you spend the time to get them right, the effort will drastically increase your chances of getting employed.
The development of virtual reality at Facebook has been evolving lightspeed in the last few years. But while a relatively small group of VR enthusiasts and gamers are enjoying the social media giant's dedication to immersive headsets, it is the augmented reality space and its potential scale that truly has the tech market enthralled.
If you live in the US, it's your civic duty to understand our governing bodies and the political system that puts them in place. It doesn't matter what your age is, knowing who to vote for is as important as voting at all. That starts with policing your own representatives to help decide whether or not we should re-elect them.
We recently set out to find the best phones for people whose primary usage revolves around social media apps like Facebook and Instagram. Samsung, Apple, and Google were the three brands that made our top five, and while the latter only had one finalist, the two bigger OEMs had a pair of phones each. What struck us, however, was that Samsung's phones edged out Apple's not once, but twice.
Many of the beauty products you buy at drug and department stores are loaded with potentially toxic ingredients like parabens, while their active ingredients are made of things like glycolic, lactic, malic, and alpha hydroxy acids and retinoids, which are all derived from foods.
A few weeks ago, Facebook published a blog post called "Proposed Updates to our Governing Documents," which outlines a few changes in their policies and user voting system. These changes would essentially take away users' right to vote on future changes to Facebook's data use policy while also taking away Facebook's responsibility to alert users of those changes. If the new policy is enacted, the vote will be replaced with "a system that leads to more meaningful feedback and engagement," what...
Let's say that you've got the look down, and you have your Steampunk props all ready to go. Congratulations! You're a Steampunk!
In the aftermath of the unindicted police killings of Michael Brown and Eric Garner, we've been told that the system worked as intended. When our legal system's outcome is at conflict with what a majority of Americans believe is just, it's clear that some changes are needed. But what specifically needs to change? And what can an average citizen with a moral and just cause do to prevent these kinds of tragedies from repeating themselves again and again?
People say that money makes the world go 'round. And it's no different in the world of augmented reality.
Just like cash, bitcoin is used for everything from regular day-to-day business to criminal activities. However, unlike physical cash, the blockchain is permanent and immutable, which means anyone from a teen to the US government can follow every single transaction you make without you even knowing about it. However, there are ways to add layers of anonymity to your bitcoin transactions.
Most of us skip through documents like privacy policies and EULAs (end-user license agreements) because they're long and boring. But, as Congress just passed the SJR34 bill in early April, you're probably a little concerned about your personal data, so we summarized the privacy policies for major ISPs and mobile carriers in the US.
Apple just announced the iPhone 6, and no matter whether you've been with Android for a few months or few years, there's a good chance you're enticed by the idea of switching over to the other side.
Today is the 10-year anniversary of the death of Apple co-founder and former CEO Steve Jobs. To commemorate the occasion, Apple has posted a message and a mini-documentary on its website.

On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
There's a lot that goes into making a nice crystal radio set, so this is going to have to be broken down into two parts. The first part is the actual making of a functional radio, and the second part is making the whole arrangement look nice. In this part, I'm actually going to tell you more than just how to make a crystal radio, but I'm also going to explain how and why they work. Crystal radios are pretty Steampunk in and of themselves, since they were first developed in the late 19th centu...
Spoofed phone calls originate from one source that's disguising its phone number as a different one, and you probably get these calls all the time. Maybe they're numbers from your local area code or for prominent businesses, but the callers are just hijacking those digits to fool you into picking up. Turns out, making a spoofed call is something anybody can do — even you.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
These days, using Reddit on your iPhone is just as good, if not better, than Redditing on a desktop browser. While there's an official Reddit app for iOS, there are plenty of third-party clients that have similar features as well as custom perks to enhance the experience. But figuring out which Reddit client is best for your daily use can be a lot of work — work that we can make easier on you.
Cases and stickers are always great, but they aren't the only way to customize an iPhone. The software on your device is full of customization options, from a better-looking home screen and cooler lock screen wallpapers to app icon changes and a system-wide dark mode. There's literally over 100 ways to make iOS on your iPhone genuinely unique, some of which are hiding in plain sight.
Smartphones are now indispensable when traveling. Domestic and overseas travel alike require food, navigation, translation, and so much more to make work or vacation successful. Gone are the days of lugging multiple tourist books around with you everywhere you go — you need to let your smartphone handle the dirty work.
The iPhone doesn't stop at last year's excellent iPhone 12 lineup. Apple's been developing its iPhone 13 models for a while now, and there are a lot of rumors already with eight or nine months still to go until a release. This year, we're expecting four new models with similar sizes and features to 2020's offerings. If you want to know what makes the 2021 iPhones so different, we've got answers.
The top-secret US National Security Agency is not required to reveal any deal it may have with Google to help protect against cyber attacks, an appeals court ruled Friday.
On this topic, Rick said: “We're looking for someone who writes what they believe in in stone and stands true to what they say."
Conservative challenger Rick Santorum announced Tuesday that he is suspending his Republican presidential campaign after a weekend of "prayer and thought," effectively ceding the GOP nomination to front-runner Mitt Romney.
NBC News has fired the producer it deemed most responsible for the airing of a selectively edited 911 call placed by George Zimmerman the night he killed Trayvon Martin.
After last night’s sweep, the writing’s on the wall: Romney, unless the extraordinary occurs, is going to be the GOP nominee… And Santorum isn’t going to win… Updated delegate count: Romney 573, Santorum 212, Gingrich 137, Paul 34… Santorum’s no-win situation heading into Pennsylvania… Obama’s speech yesterday achieved one thing: It drove the conservative intelligentsia crowd nuts… Romney, at 11:45 am ET, gets chance to respond to Obama at the very same venue… And Scott Brown embraces Obama.
