News: This Genetic Defect Could Be Why Typhoid Mary Never Got Typhoid Fever

Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...

News: Intestinal Viruses Directly Associated with Development of Type 1 Diabetes

Type 1 diabetes is an attack on the body by the immune system — the body produces antibodies that attack insulin-secreting cells in the pancreas. Doctors often diagnose this type of diabetes in childhood and early adulthood. The trigger that causes the body to attack itself has been elusive; but many research studies have suggested viruses could be the root. The latest links that viruses that live in our intestines may yield clues as to which children might develop type 1 diabetes.

How To: View Indoor Maps for Malls & Airports in Apple Maps

Apple has some great features aimed at making the lives of globetrotters and mall aficionados significantly easier, such as having detailed floor plans for airports and shopping centers in its native Maps app. With this feature available in Apple Maps, you no longer need to rely on publicly posted maps and directions that are often hard to understand.

How To: 3 Ways to Unlock Your Samsung Galaxy S8 Faster — Without Using the Fingerprint Scanner

A great many S8 and S8+ users have undoubtedly spent quite a bit of time figuring out ways to unlock their new Galaxy in as few steps as possible. One of the most endearing features of previous Galaxy models was the ability to unlock the phone by pressing the home button and momentarily leaving your finger there for the sensor to do its job, almost instantaneously opening the device — all without having to pick up the phone.

How To: Gamify Diagnostics on Your Android Phone

Running diagnostics on your Android phone can be a very tedious process. More often than not, you need to key in dialer codes to see if your device's hardware is functioning properly, though you can also download apps — but these are often hard to understand for a layperson. When a smaller component like a proximity sensor fails, you're often left with no other choice but to take it to a professional.

News: Antibiotics Could Be Contributing to Dramatic Drop in Bee Populations

Add antibiotics to the possible list of culprits responsible for honeybee decline around the world. While it may come as a surprise, antibiotics are commonly mixed into feed used by commercial beekeepers to maintain their hives. In a recent study published in PLOS Biology, researchers from the University of Texas at Austin found antibiotics used to treat honeybees may be a contributing factor in individual bee death and colony collapse.

News: Say Goodbye to Almonds—Common Pesticide Additive in Orchards Linked to Honey Bee Colony Collapse

The search for the causative agent of colony collapse—the mass die off of honey bees throughout the US and Europe—has escalated with increasing confusion lately. Everything from pesticides and stress to viruses and mites have been implicated, and some researchers think that many of these environmental factors work together to take down hives.

News: How Researchers Could Use Bacteria to Determine Time of Death

When a dead body is discovered, finding out when the person died is just as important as finding out how the person died. Determining the time of death has always involved lots of complicated scientific detective work and less-than-reliable methods. However, a study by Nathan H. Lents, a molecular biologist at the John Jay College of Criminal Justice in New York, is the first of its kind to show how microbes colonize a body's ears and nose after death.

News: MSG Is the Ultimate Healthy Flavor Hack

Hear me out. No, really. Before you sharpen your pitchforks and give me anecdotal evidence of your Chinese restaurant syndrome, I think you need to know a few things about monosodium glutamate. First of all, it's a naturally-occurring chemical compound that can be found in anything from tomatoes to cheese, and is used in all kinds of foods from KFC to breakfast sandwiches. So spare me the comments on MSG and Chinese food—you probably eat MSG on a daily basis without even knowing it. (And also...

News: I Ditched My iPhone for Windows & Went Right Back After 100 Days

I've been an iPhone user in the iOS ecosystem for years now after a brief stint in the Android realm. But, I'm also enthusiastic about varying forms of technology in general; I realize that iOS is far from perfect and that healthy market competition is beneficial for all. So, naturally being curious about other platforms, I decided to take Windows Phone for an extended trial run.

Hack Like a Pro: How to Scan for Vulnerabilities with Nessus

Welcome back, my tenderfoot hackers! Generally, you will want to perform a vulnerability scan before doing a penetration test. Vulnerability scanners contain a database of all known vulnerabilities and will scan your machine or network to see whether those vulnerabilities appear to exist. If they do, it is your job to test whether they are real and can be exploited.

Networking Foundations: Subnetting Madness

Hello everyone! How's subnetting going? Did you practice a lot? I hope you did, but even if you didn't we will go through some more examples so you can be feeling confident after reading this article. It's all about that bad boy binary!

How To: The Only 'Recipe' You'll Ever Need for Roasting Veggies

I've never had a problem with veggies—we've always been the best of friends—but I do have a lot of other people in my life that have been less than enamored with this basic food group in the past. Some cite the bitter flavor associated with veggies like Brussels sprouts, while others dislike the various consistencies that come with boiling or steaming vegetables such as broccoli or eggplant.

How To: If Cooking Stresses You Out, Mise en Place Can Help

My daughter moved into her first apartment last year, a huge rite of passage in any young person's life. With a mother and two grandmothers who are good cooks (to say the least, in the case of the latter), it's not surprising that she turned to us for some advice about how to improve her own skills in the kitchen. Without question, the single best piece of advice we have given her is to employ mise en place each and every time she prepares a meal.

How To: The Ultimate Potato Cheat Sheet: Which Potato Goes Best with What?

I've been a fan of potatoes ever since I can remember... but mainly because they weren't a big part of my daily diet (which usually consisted of rice). And because my experience with potatoes was so limited, I only knew of two varieties growing up: big, brown Russets and sinewy sweet potatoes. As for cooking with potatoes—well, I'm embarrassed to admit that the only time I cooked potatoes when I was a kid was with the instant kind.

How To: Install Android 6.0 Marshmallow on Your Nexus Right Now

Google has finally released the next version of the world's leading operating system—Android 6.0 Marshmallow. This latest iteration isn't as much of a visual overhaul as Lollipop was, but it packs in more new functionality than almost any update before it. Awesome features like Now on Tap, granular permissions control, and a deep sleep battery-saving feature called Doze round out the highlights, but there is far more to it than that.
