How To: 16 Tips for Staying Awake When You're Tired

While there's an art to surviving the all-nighter, there's also an art to staying awake throughout the day when you're operating on little to no sleep. In 1964, the record for sleep deprivation was set by 17-year-old Randy Gardner, who stayed awake for an incredible 264 hours and 12 minutes. Now while we're not out to challenge Randy for his title, we can certainly look to him for inspiration in beating back our own fatigue.

How To: Diagnose and treat jumper's knee

Another name for jumper's knee is patellar tendinitis. Jumper's knee is an injury that affects the tendon connecting your kneecap (patella) to your shinbone. The patellar tendon plays a pivotal role in the way you use your legs. It helps your muscles extend your lower leg so that you can kick a ball, push the pedals on your bicycle, and jump up in the air. Learn about the different causes of, symptoms of, and treatments for jumper's knee in this video.

How To: Diagnose and treat a dislocated shoulder

A dislocated shoulder involves movement of the ball of the humerus away from the ball and socket joint. Ninety-five percent of the time, it will come out anteriorly when an individual's arm is forcefully pushed backwards and rotated in such a way that the ligaments in the front of their shoulder tear and the ball will pop out the front of the shoulder. This is a very common injury seen in contact sports. Learn how to diagnose and treat a dislocated shoulder in this medical how-to video.

How To: Use Metasploit's WMAP Module to Scan Web Applications for Common Vulnerabilities

Having an efficient workflow is an integral part of any craft, but it's especially important when it comes to probing apps for vulnerabilities. While Metasploit is considered the de facto standard when it comes to exploitation, it also contains modules for other activities, such as scanning. Case in point, WMAP, a web application scanner available for use from within the Metasploit framework.

How To: Get Started Writing Your Own NSE Scripts for Nmap

The road to becoming a skilled white hat is paved with many milestones, one of those being learning how to perform a simple Nmap scan. A little further down that road lies more advanced scanning, along with utilizing a powerful feature of Nmap called the Nmap Scripting Engine. Even further down the road is learning how to modify and write scripts for NSE, which is what we'll be doing today.

News: Magic Leap's Neal Stephenson Reveals What It's Like to Create Content for the Secretive Startup

Getting an insider view of the goings-on at Magic Leap is hard to come by, but occasionally, the company lets one of its leaders offer a peek at what's happening at the famously secretive augmented reality startup. One of those opportunities came up a few days ago when Magic Leap's chief futurist and science fiction novelist, Neal Stephenson, sat for an extended interview at the MIT Media Lab.

How To: Extract Windows Usernames, Passwords, Wi-Fi Keys & Other User Credentials with LaZagne

After exploiting a vulnerable target, scooping up a victim's credentials is a high priority for hackers, since most people reuse passwords. Those credentials can get hackers deeper into a network or other accounts, but digging through the system by hand to find them is difficult. A missed stored password could mean missing a big opportunity. But the process can largely be automated with LaZagne.

News: Researchers Look to Cows to Create Vaccine for HIV

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.

News: Replacement Joints with Antibiotics on Board Mean Lower Chance of Infection & Fewer Surgeries

For about a million Americans each year, a joint replacement brings relief from pain and restored mobility. But, 5–10% of those people have to endure another surgery within seven years, and most of those are due to an infection in their new joint. If doctors could treat infections more effectively, patients could avoid a second surgery, more pain, and another rehabilitation.

News: How Gut Bacteria Could Set Off the Immune System in Rheumatoid Arthritis

As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from Boston has figured out how that might occur.

News: Strep Bacteria a Deadly Participant in Development of Colorectal Cancer

Colorectal cancer — cancer of the colon or rectum — is the third most commonly diagnosed cancer in the US. To reduce the chances of a diagnosis we are all urged to stop smoking, keep our weight down, decrease our intake of alcohol and red meat, keep active, and get screened for colon cancer. But, new research has found something that participates in the development of colorectal cancer that might not be as easy to control: A strep bacteria that promotes tumor growth.

NR50: Next Reality's 50 People to Watch: Tony Parisi

Tony Parisi, the global head of VR/AR at Unity Technologies, has been passionately working with virtual and immersive spaces for a long time. And while the internet world we live in now is very different than when Parisi was co-authoring VRML (Virtual Reality Modeling Language) — an early attempt at creating 3D environments that would work in a web browser — some of the questions that were assumed answered are being asked again.

News: Long-Term Follow-Up Shows Lasting, Positive Impacts of Fecal Transplants

As unappealing as it sounds, transplants with fecal material from healthy donors help treat tough Clostridium difficile gastrointestinal infections. Researchers credit the treatment's success to its ability to restore a healthy bacterial balance to the bowels, and new research has shown that the transplanted bacteria doesn't just do its job and leave. The good fecal bacteria and its benefits can persist for years.
