Dr. Christopher Lepisto on a study that proves Kolorex (Horopito) is as effective as the leading pharmaceutical drug to killing fungus, without the side effects.
A macOS computer can reveal a lot of information about the owner, including which Wi-Fi network they have permission to access. With an Arduino-based attack, we'll use a five-dollar setup to inject a rogue Wi-Fi network and steal the list of trusted Wi-Fi networks, allowing us to see where the computer has been.
Pumpkin carving and decorating is a favorite October pastime. After you've carved an amazing design or face into a pumpkin or two, you want to show it off through your window or set it out on your porch for the neighbors to see.
There's an ongoing debate about whether or not it's safe or even desirable to rinse meat before you cook it. Many fall into the anti-rinsing camp, saying that it's not effective at dislodging bacteria, especially on poultry, as we've discussed before. Meanwhile, some argue that rinsing certain meats, like bacon, could be beneficial since it possibly prevents it from shrinking.
Welcome back, my hacker apprentices! Metasploit framework is an incredible hacking and pentesting tool that every hacker worth their salt should be conversant and capable on.
I feel like doing a bit of chemistry today, how about you? To my knowledge, thermite is the hottest burning man-made substance. Thermite is a pyrotechnic composition of a metal powder and a metal oxide that produces an exothermic oxidation-reduction reaction known as a thermitereaction.
One of iOS 14's more exciting features lets you tag someone in a group iMessage chat in the same way you would @ someone on Twitter, Instagram, and other social media platforms. Even if the conversation is muted, you can get notified when you're mentioned, which helps you jump in only when needed. But if you want complete silence, then disable contact tagging notifications altogether.
Not every app is designed well. With nearly 3 million apps on the Play Store and countless more that you can sideload from other sources, there are bound to be a few stinkers. And many of them do a terrible job using RAM.
OnePlus releases some unique and exciting features before they start catching on with everyone else. Their OxygenOS is often considered the cleanest and most useful variant of Android. However, there are still a few key features OnePlus has yet to bring to their devices. This includes a proper lift to wake option.
The 2020 iPhone SE had been through the rumor mill for a long time, but Apple finally unveiled the second-generation iPhone SE on Wednesday, April 15. While it doesn't sport the 4-inch design of the original SE, it combines a small form-factor with modern specs. The big question, of course, is when and how you can get your hands on one.
SSH, or the secure shell, is a way of controlling a computer remotely from a command-line interface. While the information exchanged in the SSH session is encrypted, it's easy to spy on an SSH session if you have access to the computer that's being logged in to. Using a tool called SSHPry, we can spy on and inject commands into the SSH sessions of any other user logged in to on the same machine.
Last December, Google unceremoniously killed off Google Glass Explorer Edition with a final software update, leaving the Glass Enterprise Edition 2 as the only remaining AR wearable from Google.
Did Google CEO Sundar Pichai kill Google Glass for non-enterprise users? That's the obvious first question following news that non-enterprise Glass users will no longer have access to Google's core apps after February 2020.
If reaching up to access Camera controls like the flash, HDR, and timer wasn't bad enough, it's gotten a lot more tedious on recent iPhones like the X, XS, and 11 series thanks to their tall displays. If you have a jailbroken iPhone, however, you can easily fix this issue using a free tweak.
The game wizards at Insomniac take pride in diving deep when it comes to world-building, and the same is true for the studio's latest title for Magic Leap One called Seedling.
While last year's revelation that Apple slows down iPhones with aging batteries left a bad taste in users' mouths, the company's $29 battery replacement program was a step in the right direction. However, all good things must come to an end; Apple will soon shut down the program, leaving users to pay the full $79 to replace their faulty batteries.
WhatsApp comes with a ton of great features that make it the go-to messaging app for millions of people around the world. Among these is the ingeniously simple Read Receipts that let you know your message has been viewed. If you want to read a message without alerting the sender, however, there are simple tricks you can perform to give yourself plausible deniability.
From its official launch back in September, iOS 11 has been equal parts revered as it has been criticized. Even with all the great, new features we've come to expect from a major iOS update, plenty of bugs and glitches have forced users to overlook the positives. Perhaps that is why, four months later, 25% of iPhone owners are still running iOS 10.3 or earlier.
At this point, we've seen Samsung's vision for Android Oreo on both the Galaxy S8 and Galaxy Note 8. Just last month, Samsung opened its Oreo Beta Program for the S8 to the public. A few days ago, we obtained and detailed a leaked beta build of Oreo for the Note 8. While both of these updates have some compelling new features, there are always tweaks we hoped to see that didn't make the cut.
Karen Gillan must have had an absolute blast chewing the scenery as Nebula in Guardians of the Galaxy Vol. 2, seeing as how Nebula is a ball of pure, seething fury pretty much 24/7. Combine that larger-than-life personality with her iconic blue and silver cyborg look, and you have a guaranteed hit for cosplay or Halloween.
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...
You can send self-destructing messages in Secret Chats, but that's not the only thing that can destroy itself in Telegram after a specified amount of time. Your whole account can disappear after a certain amount of inactivity, so it's important to adjust these settings to give you more time or to kill your account even quicker.
Former Google and Uber engineer Anthony Levandowski's scathing accusations challenging the physics behind Tesla CEO and founder Elon Musk's claims about Autopilot should force Musk to make his case that self-drive cars don't need LiDAR in the next few months.
So cute, so furry, and so chock full of parasites. While raccoons are fun to watch, they are neither friendly nor clean — and they can make you sick in more ways than one.
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.
Whether your palate runs to domestic or imported, a piece of cheese can be a real treat for the senses. Its smell, taste, and texture are all parts of its appeal. A big part of what makes that savory wonderfulness comes from the microbes in and on the cheese. Thanks to a team of researchers dedicated to studying those microbes, we have a better understanding of their importance to cheese and us.
The number of households in the US that go hungry because they lack money for food hit a high of almost 15% in 2011. While that number continues to decline, nearly 13% of American households still go hungry.
If you've accidentally turned on "Read Receipts" for all of your iMessages, there's an easy way to disable it so that no one knows when you're actually reading their incoming messages. You could also pick and choose which conversations can see that you've read their messages if you don't want to kill the feature entirely.
If you've ever wanted to scour the basement of a Hollywood hotel looking for evidence of a gruesome murder spree, this new AR experience might be the game for you.
Results of an early-stage clinical trial of an HIV vaccine could mean a hoped-for breakthrough in the battle against AIDS.
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.
Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.
Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.
The new battlefield AR game announced by Skyrocket Toys today is similar to the childhood game "Tag", except the stakes are much, much higher.
When Chan Mei Zhi Alcine chose her senior project, she thought outside the box by thinking inside the bottle. Along with a research team at her university, she found a way to combine health and enjoyment, while meeting a challenge not so definitively met before in alcoholic beverages. She and a research team at her university claim they've created the world's first probiotic sour beer.
