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.
A new study has found that up to half of people who think they have a penicillin "allergy" can still receive the drug, and other antibiotics with similar structures, without any negative reactions to the meds. Why? Because they're not really allergic, doctors say.
You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body.
In this article, we will build a parallel password cracker using the techniques explained in the previous part. As SHA-512 is the digest function that Kali (and most modern Linux distributions) use to store our passwords, we will make a SHA-512 password cracker.
Few things in life are as relaxing and enjoyable as baking. When I'm having a bad day, I make cookies. When I'm stressed out, I bake a cake. When I have a free Sunday with nothing to do but listen to music and drink coffee, I bake a tart or a batch of cupcakes.
When I was 12, for some mysterious reason, my dad put my little brothers and me in charge of cooking the Thanksgiving turkey. Naturally, my brothers and I spent the rest of the day playing hide-in-seek in the backyard and forgot all about the humble bird defrosting in the sink.
Security is a priority for many when they first set up their mobile devices. Nobody wants to have a stranger or nosey friend go through their phone and discover risqué photos or embarrassing text messages. These days, the closet is gone—everyone keeps their skeletons in their phones.
Welcome back, my novice hackers! It has become clear from some of your questions that quite a few of you are unfamiliar with the hexadecimal system, or simply, hex. The hexadecimal system is used throughout computing and if you have never studied this Base16 numering system, it may appear relatively opaque.
If you save scraps of yarn, and have a dog, this is an easy project for you. The Mobius scarf has the advantage of not having any ends to come untied, or dangle down for your dog to trip over, or get tangled in branches and stuff. I made this one for Pepper, my 16lb rat terrier. Step 1: Choose Your Yarn: I had very little yarn to work with. I had one more ball, but it had just a little more on it than the largest shown here.
Continuing our series on building a dynamic user interface for the HoloLens, this guide will show how to rotate the objects that we already created and moved and scaled in previous lessons.
During the millions of years they've been on earth horseshoe crabs have developed a trick that can save our lives even now — and may be especially useful in the fight against healthcare-associated infections.
Are you looking for a little microbe magic? Think composting. Composting is a great way to reuse food and plant waste that you would otherwise throw into the trash, which would just end up in a landfill somewhere. During the composting cycle, microbes reduce this organic waste until it can be fed back into the soil as rich, crumbly compost. When returned to the soil, compost feeds plants and improves the nature of life underground. Sound like a great idea? It is — and it's easy.
While no longer native to the United States, hospitalization from malaria occurs in this country more than most would believe. Why is that, and what can you do to protect yourself when you travel abroad to regions where malaria is active?
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
Even when no one is in your kitchen, it is crowded. The refrigerator, sink, and counters are all covered with microbes that are just hanging around. They are inadvertent remnants from the raw chicken you used in that recipe last night, brewing a bacterial cocktail in your Nespresso machine, or just growing their merry little colonies on your leftovers.
Welcome back! In our last training session, we covered some advanced list topics. We'll be going deeper into the advanced list rabbit hole today with lambda and lambda operators! (And I'm not talking about Gordan Freeman)
Once upon a time in America, there was coffee and there was decaf. That's it. No capuccinos. No espressos. And certainly no Starbucks. Coffee was just coffee, something that you bought at a gas station or donut shop. If you made it at home, it was either in a metal pot or instant coffee.
The paper towel is a wondrous invention. It allows cooks to wipe up really gross stuff without having to constantly do laundry and drain fried foods so they're crunchy and crispy instead of oily and heavy. But did you know that your humble paper towel has several other uses besides the obvious ones? Read on to find out these essential hacks.

You might think you need to buy a thousand dollar phone to get a great experience while streaming movies and TV shows from services like Netflix, Hulu, and YouTube, but that's just not true anymore. While phone prices keep rising and the midrange segment now ranges from $300–$500, there are still cost-effective options that come with top-notch displays and media features.
The one thing that separates a script kiddy from a legitimate hacker or security professional is the ability to program. Script kiddies use other people's tools, while hackers and security pros write their own tools. To that end, we're going to see how a stack overflow vulnerability allows us to flood a variable with enough input to overwrite the instruction pointer with our own commands.
Lack of appetite often signals a cold or flu. Eating can be the last thing we want to do when we have a sore throat or are too fatigued or achy to even get out of bed. When hungry, we don't feel as strong as when we are well fed—and we more than likely aren't as strong.
For many, phones are starting to replace televisions as the primary device for watching videos. Thanks to their portability and easy to use apps, it's often simpler to watch Netflix, Hulu, YouTube, or Prime Instant Video on the smaller screen. But not every phone is suited to fit this need, so we did some testing to find the best of the best when it comes to streaming videos.
When it's time to calculate a tip at a restaurant or bar, I usually try some mental math at first, but sometimes I resort to opening the Calculator quickly from the Control Center on my iPhone and doing a quick calculation. But with Apple's Shortcuts app, there's an even easier way, and you don't even have to leave your lock screen to get the results.

In the case of Apple Watch v. Fitbit, the winner comes down to the judge at hand. Apple currently offers two smartwatches — the Series 5 and the Series 3 — while Fitbit offers three models — the Fitbit Versa 2, Fitbit Ionic, and Fitbit Versa Lite. Whatever your assumptions about these devices are, throw them out the window, as each has something unique to bring to the table.
In this Education video tutorial you will learn how to know if matrices can be multiplied. If the column of the first and the row of the second match, you can multiply them. For example if, matrix A has 2 rows and 3 columns (A: 2x3) and matrix B has 3 rows and 4 columns (B: 3x4), then you can multiply them. But, if A: 3x2 and B: 3x4, you cannot multiply them. The shape of the resultant matrix will be the shape of the outer numbers. For example, we saw that if A:2x3 and B :3x2, then they can b...
Use a simple mathematical formula to find the circumference of a circle. The circumference of a circle can be determined by using the formula 2 times pi times the circle's radius. Pi is equal to 3.14. If a circle's radius is 10 centimeters, first multiply pi times 2. Pi, or 3.14, times 2 is 6.28. The next step then is to multiply 6.28 times the circle's radius. Since the circle's radius is 10 centimeters, multiply it by 6.28. This gives you 60.28. 60.28 inches, then, is the circumference of t...
In this tutorial, we learn how to solve the circumference with pi. You will first need to know what to equation to figure out circumference is. C= (pi) x (diameter) is what the equation is. So, to figure out the circumference, first figure out what the diameter is. Once you have this, multiply it by pi. This will probably be on your calendar as a symbol, but you can also type it in as 3.14. After you multiply these two numbers together, the number you get is what the circumference is. Make su...
In this video tutorial, viewers learn how to solve the area of a triangle. The formula for the area of a triangle is A = ½ x b x h or bh/2. The base of the triangle is always at the bottom; it is the side that the triangle sits on. The height is the length between the base and the highest point of the triangle. Multiply the base and height of a triangle; then divide by two or multiply by half. The measurement unit of the answer should be squared. This video will benefit those viewers who need...
Learn how to calculate percentages with this easy video tutorial! One of the easiest way to calculate percentages is as follows:
Everyone has used a ruler at some point in their life, whether for art sizing, blueprint plans, or sizing up your widescreen television on your living room wall. But there's a lot of little ticks on the ruler that you may not be aware of. Your ruler shouldn’t be used only to draw a straight line. Make sense of all those little lines and take advantage of its intended use.
In this video you can learn how to find the area of a hexagon. Visualize that the hexagon is made up of six equilateral triangles, with each side of the hexagon as the base for a different triangle. Determine the length of any triangle side by measuring it. Each side should be equal in length to any other side. L will represent this number. Determine the height of any triangle. This can be done by putting one end of your ruler at the halfway point on any side of any triangle and the other end...
