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...
The next time you suffer a cut or abrasion, think twice before you reach for the Neosporin. It's time, and mom, tested — you get a cut, you wash it carefully, then apply some triple-threat antimicrobial ointment. You may or may not slap on a band-aid. We won't cover it here, but so that you know, covering the wound with a sterile dressing or band-aid is a good idea.
Amidst reports of the newspaper industry struggling to survive, it's becoming more and more clear that people are increasingly turning to their smartphones for the news. In fact, a new study by the Pew Research Center has found that 85% of US adults check the news on mobile devices. Surprisingly, seniors constitute a sizable portion of this.
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?
Just like in the Spy Kids 3D movie, US soldiers may soon upgrade their mission planning from 2D to 3D. Welcome to the wonderful world of augmented reality, US Army.
Bacteria gets a bad rap. Most headlines focus on the danger and discomfort posed by pathogens like bacteria, but many of the bacteria that live on and in us are vital to our health. Many products out there, called probiotics, are sold with the implication that they're supporting these healthy bacteria that share our bodies — but do they actually work?
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.
Take one down, pass it around, 99 bottles on which to play classical music? As someone who has studied music extensively, I've seen many interpretations of famous pieces of music played on glass bottles, but hearing these four interpretations of famous pieces (not all classical) completely blew my mind.
When a new version of iOS comes out, everybody gets caught up in the craze of finding features and playing around with new functionality. But this generally leads to a lack of coverage on the finer aspects of the update—things like bugs, minor tweaks, and pain points that users discover along the way.
The Null Byte community is all about learning white hat hacking skills. In part, this is because I believe that hacking skills will become the most valuable and important skill set of the 21st century.
Welcome to my tutorial where Voidx and I will be expanding on my previous article to provide more clarity into the logic of the code.
I am very new to Null Byte but I find much of its content and community incredibly interesting. I spent quite a bit of time just chronologically going through the posts and I noticed a common theme in many of the beginner posts. Many people seem to want to know the 'secret' or a paragraph on "How to Hack" and become a hacker in a few minutes. I started off this post as a reply to a question from a beginner but thought it might be beneficial to have for those stumbling across this site.
Did you know that your face shows others how much alcohol you drink? Whether you've never had a sip of booze with those around you or you're known as the party animal of the group, the genes that shape your appearance also show others just how much you enjoy liquor. Pinpointing the big drinker in any setting is easy to determine: you just need to make eye contact.
Are you someone who always struggles to wake up in the morning, no matter how much you've slept? For most, the thought of getting out of bed any earlier sounds horrific. Yet dragging yourself out of bed and towards the coffee maker a few hours earlier each day can have benefits you've never realized. Here are six reasons that make a compelling case for ending our bad habit of sleeping a little too long.
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.
Although your friends might roll their eyes every time you talk about playing Clash of Clans, Call of Duty, or Candy Crush Saga, your excessive gaming habits might actually be making you healthier than everyone else.
We all know that it's important to drink water regularly throughout the day. After all, it has so many benefits, including flushing toxins out of the body and maintaining kidney health and good bowel movements. Turns out that's only part of the story. While being properly hydrated is key to maintaining overall health, it's also a big component of maintaining and even increasing cognitive ability. Plus, drinking enough water regularly can help you lose weight, if you know when to drink it and ...
We've all walked into a restaurant with the best of intentions only to order something absurd, like a cheese-injected burger topped with bacon on a brioche bun. It's delicious for the few minutes it takes to eat the thing, and then you're left with a bellyful of regret and an inability to directly look at the numbers on your scale. Turns out that getting yourself to make healthy choices isn't as hard as one might think.
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.
Welcome back, my novice hackers! My recent tutorials have been focused upon ways to NOT get caught. Some people call this anti-forensics—the ability to not leave evidence that can be tracked to you or your hack by the system administrator or law enforcement.
Hey dolls! I have to share the secret of Copper peptides with you all. I don't know why it's taken me so long to jump on this band wagon because the science and studies behind the product are amazing!
The vast majority of people involved in Steampunk are interested in history but, like with science, there's something about history that we don't talk about very often: The holes.
No matter how many PSAs are published on the topic, studies continue to show that we are generally terrible at creating secure passwords and PINs. Using the same password (or variations of it) for multiple sites is another huge no-no that the majority of people ignore, and even though you should change your passwords frequently, most of us don't.
Motion can be studied in different dimensions. Study of motion of a body in a straight line is called motion in one dimension. A falling body can be called as motion in one dimension. Things can also move sideways when they fall at the same time. This is also called as projectile motion and it is a study of motion in two dimensions. When studying projectile motion we can neglect one dimension of the motion and study the other dimension obtaining the results of motion in that dimension. If a b...
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.
Apple just released iOS 13.5 for iPhone developers today, Monday, May 18. This GM (golden master) update comes 12 days after the release of iOS 13.5 dev beta 4, which introduced updated COVID-19 exposure notification logging settings and the ability to share your Medical ID with first responders when placing an emergency call.
Did you take a vacation this holiday season? It appears Apple did. After the release of iOS 13.3.1 developer beta 1 (then public beta 1 one day later), iOS beta testing went silent for almost a full month. With 2019 now in the books, it seems Apple is back to work, as developers received iOS 13.3.1 beta 2 today, Tuesday, Jan. 14.
Two-factor authentication (also known as 2FA) adds a necessary additional layer of security to your username and password in many important apps. On Instagram, 2FA requires you to confirm it's you attempting to log in, with a special code sent to you via text message. Enter the code and you're in ... but what happens when you need to log in and don't have access to your phone?
For many of us, getting to inbox zero is the highlight of our day. But if you used your email address to sign up for various sites and services, your inbox is probably cluttered with all sorts of spam, news letters, and unimportant emails. Thankfully, Gmail has a feature that can solve this by using machine learning.
You seriously won't even recognize Twitter after this. Twitter has launched a major redesign, their first in years and it seems the app is finally starting to listen to what users are looking for — starting to being the keywords.
We all know the internet isn't exactly a safe place. While plenty of its users are innocent and kind, you won't last long unless you treat every new screen name like a criminal (we're all this cynical while surfing the web, right?). Well, that cynicism is proven correct today, a post on Medium uncovered a group of scammers on the iOS App Store that are costing victims up to $400 a month.
Cyanogen, Inc., the for-profit company that spun off from its CyanogenMod roots several years ago, has announced that they're shutting down all of their services. The company's impending demise shouldn't directly impact many Android users, but the announcement does have one major repercussion: The servers that used to host the popular CyanogenMod custom ROM have now been shut down.
Kryptowire, a company specializing in mobile security solutions, released a report on Tuesday, November 15 that exposed firmware in a number of Android devices that was collecting personally identifying information (PII) and uploading it to third-party servers without users' knowledge.
When you're browsing the internet on a computer, you just need to hit Ctrl F (or Command F) and type something out to find all instances of that word in the webpage. It's a handy feature baked into most browsers (nearly all mobile browsers have a "find" feature, too), but unfortunately, it doesn't work with real-world documents, signs, and menus—or at least it hasn't, up until now.
When it comes to sharing files between a smartphone and a computer, there are several solutions available for a Windows and Android pairing. But for those of us with Apple devices, the selection of apps in this category isn't quite as great. You can use AirDrop to quickly share files, but searching for files is not so easy.
GIFs are awesome, but GIFing from your keyboard is some next-level stuff, and Apple knows this. That's why they've included a way to find and send GIFs in Messages from the stock iOS 10 keyboard. However, iOS 10 is not out for the public just yet, so if you want to easily send GIFs in your messages, you'll have to settle for a third-party keyboard.
When it comes to news, updates, and arbitrary nonsense, it's hard to find a better source than Twitter. And for some of us, the best way to consume Twitter is through the web (versus a mobile app). But as much as I prefer the standard browser version, it's easy to make it better, faster, and more convenient using a few Chrome extensions—and here are my favorites.
After my hard drive crashed recently, I lost everything. Old college essays, half-written stories, short films, and most importantly, all of the photos that I had saved from the past five years... all gone.
Hello you sexy, savage, surreptitiously tech-savvy penetrators (Pun intended)!
My reliance on autocorrect has made me a horrible speller. I take it for granted that it'll catch all my mistakes, but it only ends up making matters worse (especially when it inadvertently makes correct words wrong). So instead of relying on autocorrect to fix typos, why not try to completely prevent mistakes from happening in the first place?
