Transmitted by a sandfly one-third the size of a mosquito, parasitic Leishmania protozoa are responsible for a flesh-destroying disease that kills an estimated 20,000 people per year. Two new studies offer understanding of how the parasite provides immunity through persistence and why some people suffer more virulent forms of the disease.
Where in the world did it come from? All of a sudden, one day, someone had an infection with flesh-eating bacteria. It captured headlines and worldwide attention because it was such a severe, strange, uncontrollable, and really disgusting condition.
In the summer of 1976, 4,000 American Legionnaires descended upon the Bellevue-Stratford Hotel in Philadelphia, Pennsylvania, for a four-day convention. Several days later, many of the attendees experienced symptoms of severe pneumonia. By the beginning of August, 22 people had died. The Centers for Disease Control and Prevention (CDC) estimate that about 180 people were sickened and 29 people died before this mysterious outbreak burnt out.
Lighthouses and signal fires may have been the first social media. Without the ability to share language, a distant light meant "humans here." A new study from the University of California, San Diego, finds that bacteria can also send out a universal sign to attract the attention of their own, and other bacterial species.
Over 1.2 million people in the US are infected with human immunodeficiency virus (HIV)—and one out of eight of them don't know it. Even after decades of intense research into the virus, there's still no cure for it. One of the big problems is that the virus hides out in certain cells of the body, resisting treatments that kill it.
A recent pathogen outbreak in Illinois is just one of many outbreaks of an underappreciated, but serious, viral infection passed from rodents to humans. These hantaviruses have been cropping up more frequently in the last decade or so, giving us more reason to clean out our dusty attics, basements, and garages.
I know I'm in the majority when I say that grilled cheese sandwiches are one of life's simplest and best pleasures: gooey, rich, melted cheese, sandwiched between two perfectly-buttered pieces of toast... perfection.
If you're anything like me, you probably think it's borderline sacrilege to even think about a sandwich or a burger that doesn't have a layer of smooth mayonnaise. But I don't just keep a jar of it in my fridge for lunch—it's also there for practical purposes.
There are so many cutesy pink, red, and heart-shaped desserts and drinks put out on Valentine's Day, but none of those really get you into a low-light mood. Instead, turn up the heat with one of these aphrodisiac cocktails for grown-ups.
Sitting in a cubicle and never seeing sunlight during the workday is unpleasant to even think about—and sitting in a flourescent-light cube can have terrible effects on both our work performance and overall attitude. Yet there are ways to counteract the effects of cubicle sitting, even if you can't sit in a sunny office or work from home.
Welcome back, my neophyte hackers! As part of my series on Wi-Fi hacking, I want to next look at denial-of-service (DoS) attacks, and DoSing a wireless access point (AP). There are a variety of ways to do this, but in this tutorial we'll be sending repeated deauthentication frames to the AP with aircrack-ng's aireplay. Remember, hacking wireless networks isn't all just cracking Wi-Fi passwords! Our Problem Scenario
WonderHowTo is a how-to website made up of niche communities called Worlds, with topics ranging from Minecraft to science experiments to Scrabble and everything in-between. Check in every Wednesday evening for a roundup of user-run activities and how-to projects from the communities.
This week, Apple unveiled its own version of Google Lens in the form of Live Text. In response, Google just hit back with a new feature for its visual search tool called Places, a new search category that can recognize landmarks and return information on them within the camera view, which Apple touted as a capability of Live Text during its WWDC keynote.
With the new season of The Mandalorian underway, Google has launched a new AR app that enables some Star Wars fans to connect with virtual characters in between new episodes.
Every single photo you take carries with it a considerable amount of seemingly "invisible" yet important information known as metadata. Although metadata is usually helpful to sort your photographs by location and date, that same information could potentially be used against you, especially if the pictures are taken during a precarious situation.
One of the standout features of the OnePlus 7 Pro is the 90 Hz display. A higher refresh rate means smoother gameplay for all your favorite games, which is precisely what you'd want out of your gaming experience. However, not all games play nicely with these higher refresh rates — but luckily, there's a pretty simple fix.
Thanks to its free-to-play strategy, many items in Fortnite Battle Royale require V-Bucks, the in-game currency. You can purchase V-Bucks with real-world money, but many would rather earn V-Bucks instead of getting nickeled and dimed by micro-transactions. While limited, there are a few ways to earn free V-Bucks in the game.
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.
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.
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.
Killing more than 29,000 people each year, infection with Clostridium difficile (C. diff or CDI) is the most common healthcare-associated infection in the US. In a disturbing development, new research reveals recurring cases of the infection are soaring.
The best go-to method for reducing your risk of infection is to wash your hands. Next time you reach for the soap, here is some news you can use.
Tell the truth. The bat picture creeps you out. You are not alone. But in reality, bats truly are some of our best friends. They gobble thousands of disease-spreading bugs a night. But they also carry viruses that can be deadly to humans. So, bats — friend or foe?
While it is easy to create and maintain your compost pile, you can enjoy it more knowing a few basic tips.
HIV-infected people who are treated long-term with antiviral drugs may have no detectable virus in their body, but scientists know there are pools of the virus hiding there, awaiting the chance to emerge and wreak havoc again. Since scientists discovered these latent pools, they have been trying to figure out if the remaining HIV is the cause of or caused by increased activation of the immune system.
If you have encountered bed bugs lately, you are not alone. While the pesticides used to fight these pests are losing effectiveness, a fungus shows promise in knocking the bugs out of beds everywhere.
Bacteriotherapy sounds a lot more amenable of a term than "fecal transplant," yet they're both treatments that use bacteria itself to cure or treat infections. Fecal transplants, specifically, are an up-and-coming treatment option for a potentially deadly and difficult-to-treat diarrheal infection called Clostridium difficile.
Joe McKenna died when he was 30 years old. A young married man with his future ahead of him, he was cleaning up the station where he worked as a fireman. Struck by a piece of equipment fallen from a shelf, Joe complained of a sore shoulder. Over the next week, Joe worsened and ended up in the hospital. Chilled, feverish, and delirious, his organs shut down from an infection we'd now call septic shock.
Instead of suffering through long, dull meetings with your supervisors and coworkers, you can turn those office table sessions into your very own psychological experiment.
As a regular Mac OS X user, I have a love/hate relationship with the "Open With" contextual menu. Sometimes, it has just what I need. Other times, it's often packed with unnecessary or duplicate items, or missing the app I want to open the file up with the most.
Ever since the much-lauded effects of the Mediterranean diet became widely known, people have been buying olive oil by the gallon. A diet that prevents heart disease, is based on fresh, seasonal foods, and includes a tasty as hell fat like olive oil? Duh—that's a no-brainer.
Welcome back, my novice hackers! There are SOOOO many ways to hack a system or network, which means you need to think creatively in order to be successful.
It's rare that a developer listens to the wishes of the masses, but that's exactly what CyanogenMod has done with their new CyanogenMod Installer, which automates the entire ROM installation process on your HTC One or other Android device. Previously, upgrading from the stock HTC One ROM to CyanogenMod required an unlocked bootloader, a custom recovery, the latest CM version, and Gapps. Let's be honest—unlocking the bootloader is a pain the ass, and probably the only reason stopping most peop...
Welcome back, my novice hackers!
In Minecraft, a large aspect of the game is PVP (Player vs. Player Combat). A hardcore Minecraft fan will remember that back in Beta 1.8, combat was switched up, and it really changed the game around. Here are some tips on what a two-year Minecraft player has to say.
I've tried my hand in the past at defining Steampunk, but as anyone else who has made a similar attempt will tell you, there's a significant backlash from the community against working to create a real definition of what Steampunk is. That may sound ridiculous to some, but it's a very serious matter to others. With the recent announcement that TeslaCon 4 will be called the Congress of Steam, I think it's appropriate to talk about why all of this stuff is worth it. In this article, I'm going t...
If you're in an active Messages chat, writing a large email, or have a lot of notes to jot down, you might be acutely aware of just how loud your iPhone's keyboard can sound — especially with AirPods or other headphones on. "Click, click, click, click, click, click." If the fake keyboard sounds are driving your crazy as you type, there's something you can do about it.
Even for those of us who enjoy spending time alone at home, at a certain point, it just gets boring. We all need social interaction, but with stay-at-home orders, that can be hard to come by. If you're feeling the itch to hang out with friends and have a good time, you should know there are plenty of free multiplayer games for iPhone and Android that will let you do just that — remotely.
If you've ever needed to prove you have remote access to a device, or simply want a way to convince someone their computer is haunted, SSH can be used to make a device begin to show signs of being possessed.
SSH is a powerful tool with more uses than simply logging into a server. This protocol, which stands for Secure Shell, provides X11 forwarding, port forwarding, secure file transfer, and more. Using SSH port forwarding on a compromised host with access to a restricted network can allow an attacker to access hosts within the restricted network or pivot into the network.
