Welcome back, my budding hackers! People often ask me, "Why are you training hackers? Isn't that illegal?" Although I usually give them a short version of this post, there are MANY reasons why YOU should be studying hacking.
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.

A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.
Bacteria, viruses and other germs sometimes set off the immune system to overreact, producing a severe condition called sepsis. Sepsis is so dangerous that it is the leading cause of death of children across the world, killing a million kids every year, mostly in developing countries. Probiotic bacteria might be able to prevent sepsis and infections, but no large research studies have been done to find out whether that actually works. Until now.
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
Move over whole wheat — white bread may be back in style after a new study shows that it may be your gut microbes that decide what kind of bread is best for you.
As summer mosquito season approaches, researchers are warning people with previous exposure to West Nile virus to take extra precautions against Zika. A new study found that animals with antibodies to West Nile in their blood have more dangerous infections with Zika than they would normally.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
In this free video math lesson YAY MATH, we learn how to simultaneous equations — sets of equations with multiple variables — in basic algebra. With mathematics, as with anything else, not everyone progresses at the same rate. Algebra is no exception. Happily, in the age of Internet video tutorials, this isn't a problem. Those who progress quickly can go beyond what's being taught them and those who are struggling likewise have all the time in the world to catch up. Whether you need help fini...
See how to solve quadratic equations in algebra through factoring with this free video math lesson. Factoring quadratic expressions is easy once you know the system. Learn it with this how-to. From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts. And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test).
Learn two quick study habits that will help increase your grades on tests and exams.
If high school students spent as much time on studying as they tend to spend on looking for new ways to cheat, everyone in America would have straight A's. But, cheating is so much more fun than studying, isn't it?
We might think of Zika as a mosquito-borne virus that effects developing fetuses, but, it also can be passed through sex by either a man or a woman, just like herpes and other STD viruses. New research has shown that vaginal bacteria can inhibit sexually transmitted Zika virus and Herpes Simplex Virus-2 in women.
By connecting the dots between theory and real-life effect, two new studies offer more proof that neonicotinoid insecticides are causing extensive damage to honeybee colonies.
The body's usual response to a bacterial infection in the blood — called sepsis — takes time. It requires a carefully orchestrated sequence of events that gets the body's immune system ramped up to deal with the invading bacteria.
Electrical impulses course through our heart and keep it beating. That's why a jolt from an automated external defibrillator can boost it back into action if the beating stops. But new research says there may be more to keeping a heart beating than just electrical impulses.
Maternal infection with genital herpes, or other pathogens, during early pregnancy could increase risk of autism, or other neurodevelopmental disorders, says a new study.
Since I first announced the new Null Byte recognition for excellence a few weeks ago, several of you have written me asking, "How can I study for this certification exam, and what material will be covered on the exam?" Now I have an answer for you. The White Hat Hacker Associate (CWA) will cover 14 domains or areas. Everything you need to know is here on Null Byte. There will be no questions that are not covered here on this site, guaranteed.
The flash card is one of the most effective and distinctly old-school methods of studying. If you want to eschew the computer and bust out the flash cards, watch this video to learn some ways to make more effective flash cards and rock your next test.
Kids would usually rather play than do their homework, but follow these parenting tips to make studying fun for them. Determine your child's learning style, and tailor homework time specially for them. Remove distractions from the environment so kids can focus on their education and passing the next test.

Do you write down everything you hear—then get overwhelmed when it’s time to study? Save time—and improve your grades—with this note-taking system. Learn how to take good notes in class with this Howcast guide.
Palm reading can be complicated because chirognomy, the study of the mounts of the hand, sometimes contradicts chiromancy, the study of the lines of the hand. For that reason, it's best to do a reading as a whole. In this particular video palmistry tutorial, Peter John explains the significance of the thumb, highlighting the areas on a detailed map of the hand. Watch this instructional palm-reading video and learn how to interpret the meaning behind the thumb.

Law and business are frequently connected more closely than many are comfortable with. Thus, writing business case studies is a big part of legal life in law school and when working at a firm. Watch this video to learn how to write a great business case study.
Studies have shown (yes, there have been studies on this) that the keyboard and mouse control setup employed by PC gamers is better for first person shooters than a console controller. Fortunately, there's a nifty peripheral for the Xbox 360 called the XFPS Sniper that allows you to connect a keyboard and mouse to the console and use them to control your characters in Call of Duty, Halo, Gears of War, or whatever other of the dozens of shooters on the XBox 360 you play. This will give you a p...

Rising on the world stage, dengue fever is transmitted by mosquitoes — and apparently air travel too.
Young girls, especially those who live in areas where HIV is epidemic, like sub-Saharan Africa, are particularly vulnerable to becoming infected with HIV. A vaginal ring containing the antiviral agent dapivirine has been shown to decrease the chance of developing HIV-1 in adult women over 21 and now in the first step for use in adolescents, the ring has been shown to be safe and well-tolerated in that younger age group.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
