Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
Coronaviruses are common viruses, and most of us catch one at some point — they cause about 30% of all common colds. A new accidental discovery could help fight these viruses, even the deadlier, emerging ones.
Facebook is testing a new feature in India. One that could help you protect your profile photos from being used on sites without your permission.
Citrus greening disease — caused by a bacteria spread by psyllid insects — is threatening to wipe out Florida's citrus crop. Researchers have identified a small protein found in a second bacteria living in the insects that helps bacteria causing citrus greening disease survive and spread. They believe the discovery could result in a spray that could potentially help save the trees from the bacterial invasion.
Bioluminescence — the ability of an organism to produce and emit light — is nature's light show. Plants, insects, fish, and bacteria do it, and scientists understand how. Until now, though, we didn't know how fungi glow.
A disease called "citrus greening" has devastated and permanently altered citrus production in the United States, but a vaccine that could protect orange trees may be part of a winning strategy to beat the bacteria that is killing the trees.
Growing populations and higher temperatures put pressure on world food supplies. Naturally occurring soil bacteria may save crops in drought-stressed areas, put more land into crop production, and produce more food.
To keep fungal pathogens at bay in their crowded homes, wood ants mix potions to create powerful protection for their nest and their young.
Tremendous strides have been made in the treatment and outlook for patients infected with HIV, the human immunodeficiency virus. Treatment with a combination of antiretroviral drugs can keep patients with HIV alive for decades, without symptoms of the infection. The trouble is, if HIV-infected people stop taking their medications, the virus takes over in full force again—because the virus hides out quietly in cells of the immune system, kept in check, but not killed by the treatment.
Cholera is rapidly spreading in Mozambique, with over 1,200 people infected. Since the outset of 2017, cholera has spread from the capital city of Maputo (pictured above) to three of its ten provinces. Health officials report other areas in the country are seeing case counts rise, and two deaths have been logged so far.
In the past, infection with human immunodeficiency virus (HIV) commonly led to dementia as the virus made its way to the brain. Even in effectively treated people, HIV can hide out and replicate in places like the brain, where it's tough to detect. That's why it's very concerning that half of all HIV-infected patients still report cognitive problems.
We may not fully appreciate all the important roles wheat plays in our lives until it's gone—or at least, when it's in very short supply. What would a world be like without bread, cakes, cereal, pasta, or wheat beer? If the dire warnings about an impending stem rust fungus come to pass, we may know all too soon.
Seagrass may help your favorite beach stay a little less toxic. A new study, led by Joleah Lamb, a postdoctoral researcher in the Harvell Lab at Cornell University, found that coastal seagrasses reduce levels of pathogens dangerous to humans and marine organisms in near-shore waters.
Using extreme time-lapse microscopy, scientists watched a virus take over a bacteria to create a cell that looked and functioned more like a plant or animal cell. True story.
Whether you made the switch from iOS, or you came from a different Android device, there's a lot to learn about your new Galaxy device. Samsung does things a bit differently, and thanks to their TouchWiz interface, there are tons of added features to take advantage of—though some folks might find these extras to be a bit too much.
We haven't had a working jailbreak method since October of last year, and that only worked for about a month until iOS 9.2 came out and shut down the loophole it was using. So all of those cool Cydia tweaks have been out of the question for quite a while now, unless you downgraded your firmware to keep jailbreak compatibility.
To become a tried-and-true Pokémon master in Pokémon GO, there's an incredibly important decision that needs your attention: Team Instinct, Team Mystic, or Team Valor?
The octopus is famous for its bulbous head, enormous eyes, and four pairs of long arms. The stuff of legends and nightmares, octopi have been featured in stories, artwork, and meals galore. But how do you eat this distinctive looking, bilaterally symmetrical sea creature?
Google Photos is one of the best photo management services out there. It allows you to back up an unlimited amount of high-quality images without ever paying a dime, the photos and videos sync flawlessly across all of your devices, and its neural network-powered visual search feature seems like something that was pulled directly out of a Sci-Fi movie.
We keep at least half a dozen hard-boiled eggs in the fridge for times when we're on the go and need a quick snack. Often, we eat them sliced in half with a pinch of sea salt and black pepper, or we just make some deviled eggs or a quick egg salad—but these gets old very quick, and our creativity tells us to do otherwise.
Google has a lesser-known Android app called Device Assist that might just be one of the most useful programs the company has ever published. It offers interactive guides and general tech support for Android, plus it can diagnose your device and help you fix any issues it finds.
Greek yogurt has always been in my regular snack rotation. Packed with more protein than plain yogurt, it fills me up and stabilizes my energy with its low levels of carbohydrates and sugar.
Macs are generally highly power efficient due to, in part, the optimized sleeping schedule with OS X. Yet in certain scenarios, you might not want your Mac to go to sleep: downloading a huge file, reading a book, reviewing a spreadsheet, analyzing some content on the screen... the list goes on. To resolve this, you can go to System Preferences and mess with the settings, but this can be an annoying process if you need to do it often.
Welcome to a tutorial on XOR encryption. We'll be looking at what XOR is and how we can use it to encrypt or decrypt data.
Hello there! This will probably be the final tutorial on functions where we will be looking over a method called pass by reference. This technique allows us to modify large amounts of data without the overhead and return multiple values. Let's go!
The end of a weekend can be depressing knowing just how bad Monday morning will be when you get back to work, but that feeling is tenfold when coming back from a lengthy vacation with zero work responsibilities.
In previous tutorials we have encountered these things called pointers and addresses but we still don't know what they really are. Let's learn a bit more to clear things up.
Welcome back to another tutorial on functions. Last time, we looked inside memory to see what functions looked like in the flesh and all that Assembly was pretty nasty. At least you have some exposure to it. This time, we will be examining how functions work with the stack.
If you have no desire to get a separate Mac desktop computer, but want to either supersize your laptop's screen for gaming or need to get additional screen real estate while you work, then connecting your MacBook, MacBook Air, or MacBook Pro to an external display is the right call.
3D Touch is a new feature on the iPhone 6S and 6S Plus that's reinventing the way we interact with our smartphones. With just a little bit of added pressure when tapping on the display, you can perform Quick Actions from an app's home screen icon, "Peek" at emails, stories, and photos in-app, as well as perform other app-specific gestures. Since 3D Touch is such a new concept, here are some of the apps that currently support it, along with the shortcuts you can use.
Instead of wasting time asking where your friends and family are at a given moment, then having them waste time by describing their location, there are several Android apps you can use that will automate this whole process. To top it off, it doesn't have to be about invading privacy or spying on someone, since most of these apps are offer two-way location sharing, or at least let you share locations only when you feel comfortable with it.
Newer gaming systems like the PlayStation 4 have a nice, subtle feature that goes a long way towards helping create a more immersive experience. Any time you're on the main menu or home screen, an ambient background music track is playing, which adds an aural appeal to an experience that would otherwise be all about the visuals.
Your average Android phone or tablet comes with quite a few apps already installed—even before you turn the device on for the first time. These pre-installed apps are certainly helpful when it comes to getting your feet wet with Android, but in many cases, they're not always the best apps available for accomplishing the tasks that they perform. Additionally, many third-party apps can add lots of cool functionality to your device, so you might say that sticking with only the pre-installed apps...
I've never met a person who doesn't love French fries. And, to be frank, I have no desire to meet such a person.
For foods that encompass both tastiness and convenience, it's hard to beat boxed mac and cheese. Mac and cheese in a box takes 15 minutes to make, dirties only one dish, requires no skill, costs only two bucks, and is, despite all of the above, wildly delicious. Yet it can get even more delicious just by adding a few more ingredients.
If you're a child of the '70s, then you'll probably remember Pop Rocks, those fizzy little candies that created such a buzz. They went out of style in the States for a while, but now they're back with retro status. I was surprised to see them in my kids' Halloween bags a few years ago, and one taste brought me back to my childhood.
It's that time of year again, folks. Each fall, Google debuts a new device alongside the latest iteration of its mobile operating system—but this year marked the release of three new Nexus gadgets.
With Safestrap bringing custom recovery functionality to the AT&T and Verizon Wireless variants of the Samsung Galaxy S5, it's high time we covered this process for all other versions of the GS5.
When people first learn that their Android device is capable of dual-booting different operating systems, e.g. Linux, they almost universally respond with, "That's so cool." And for those of us ambitious enough to actually try one out, we are typically filled with glee as we see Ubuntu, or something similar, boot up for the first time on our tablet or phone.
Contrary to popular belief, taking someone's mind off their sadness and telling them to "cheer up" doesn't do much good. Misery loves company, and while it may be a tiresome cliché, there's actually some science behind it.
