A tiny louse is responsible for decimating the citrus industry. Diaphorina citri, the louse in question, better known as the Asian citrus psyllid, harbors and spreads the "Candidatus Liberibacter asiaticus" bacteria that causes citrus greening disease.
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.
A young child becomes very thirsty very often and seems tired all the time. A visit to the pediatrician determines she has type 1 diabetes. The onset of type 1 diabetes may seem sudden, and it can be, but the disease may actually have been triggered by common childhood viruses years earlier.
Cholera may be rare in the US, but cases of the disease have increased worldwide since 2005, particularly in Africa, southeast Asia, and Haiti. An estimated 3 to 5 million people are infected, and more than 100,000 die from the disease globally each year, mostly from dehydration.
You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body.
Since the 1960s, bacteria have been hopping a ride into space on space vehicles and astronauts, and have been cultivated within experiments on space shuttles and the International Space Station (ISS). The extreme growing conditions and the low gravity environment on the Earth-orbiting vehicles offers a stable research platform for looking at bacteria in a different light.
Pain is, for the most part, unavoidable when you stub your toe, break your arm, or cut your finger open. It's instantaneous and, in some cases, long-lasting, but it only feels as bad as you want it to. Yes, that's right—that pain is all in your head.
We've all been there: facing a lengthy, complex word that ignores the phonics we were taught in elementary school, unsure of not only its pronunciation, but also its meaning. These words, from autochthonous to esquamulose, are both terrifying and impressive. After all, if someone knows how to use them—and even say them—they must be quite smart. Yet before you begin stuffing every email and presentation with verbose prose, you might want to reconsider what others perceive to be intelligent.
There are certain foods and beverages that can actually brighten your smile or improve your dental health when you chew or sip them. Once you understand their chemical properties or textures, you can look to items you already have in your cupboards or refrigerator to help keep your teeth looking and feeling their best.
Can you tell when someone is shooting you a fake smile? Even though fake smiles are easy enough to see through, we all still do it, attempting to show others just how happy we are when we're really feeling less than fantastic. Unfortunately, every smile we fake makes us a tiny bit more miserable.
Complete silence or a non-stop Pandora playlist? People are often divided on what type of work environment they prefer. Whether you're a frequent loud music listener or you can't stand any kind of background noise, chances are you're pretty set in your ways.
Journals are a great source of hilarity and embarrassment, detailing everything from your elementary school crushes to those super awkward middle school dances. While rereading your old hand-scrawled entries might make you cringe, that old journaling habit could benefit you as an adult.
Whether you like it or not, certain songs get stuck in your head. You might be driving to work or school when suddenly Cher's 1998 lead single "Believe" plays on the radio.
We go to such great lengths to secure our smartphones. We put passwords on our lock screens, encrypt our data, and install anti-theft programs, but it's never enough—someone, somewhere, will find a way around any protective measure you use, no matter how sophisticated.
At its F8 developer's conference in 2016, Facebook went on record with a roadmap that called for augmented reality integration into Oculus within 10 years. Now, it appears as though Facebook is accelerating those plans.
After joining Google and Huawei in underwriting the UW Reality Lab at the University of Washington in January, it appears Facebook is already seeing a return on its donation.
The addition of a new research mode for Microsoft HoloLens will enable researchers and developers to tap into a wider range of data collected by the device's sensors.
We've seen a number of unique mashups of augmented reality with other bleeding edge technologies, but somehow it took until 2018 for someone to come up with a now obvious complement to AR: 3D printing.
In the case of rotting food, microbes are not our friends. Now, scientists have developed a new food wrap coated with tiny clay tubes packed with an antibacterial essential oil that can extend the shelf life of perishable food, so we can waste less and eat more.
People infected with HIV take many different types of pills every day to decrease the amount of virus in their body, live a longer and healthier life, and to help prevent them from infecting others. That could all be in the past as new clinical trials testing the safety and effectiveness of a new type of treatment — injections given every four or eight weeks — look to be equally effective at keeping the virus at bay.
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...
Windborne microbes shifting in the snows of the great ice sheet of Greenland may be able to neutralize some of the industrial contaminants oozing out of the melting ice.
Most people are familiar with the decline of honeybee colonies around the world. Among other threats, Colony Collapse Disorder (CCD) is eroding the capability of honeybees to maintain their hives and provide their services to human farmers.
A new study published on April 12 in Medscape gives us an update on the Hantavirus genus of pathogens, which spread viruses via rodents that can cause fatal diseases in humans, such as hantavirus pulmonary syndrome (HPS).
Could the technology that powers games like Pokémon GO be used for surgery in the near future? Researchers at the University of Maryland think so.
A few lines of code in the iOS 9.1 library cache found by Chase Fromm (@uloshe) indicate that Apple could be working on making iPhones that are Li-Fi compatible.
Nothing gets me functioning in the morning better than strong coffee. And if I'm going to start my day with a dreaded workout, that steaming cup of caffeine is the exact motivation I need to get going. Although coffee might not seem like the best beverage to drink before hitting the gym, it actually has a few hidden benefits over water that may surprise you.
White rice is cheap, filling, and tasty. No wonder so many countries in the world rely on it as a mealtime staple, including most of East and Southeast Asia. Alas, because of its relative lack of nutrition and its high calorie count, consuming lots of white rice regularly also puts people at risk for diseases like diabetes and obesity.
Each morning, we spend a significant portion of our time staring into the mirror. From choosing clothes and accessories to perfecting our hair, we try to make ourselves attractive. Yet catching others' attention doesn't have to rely on preening and primping. There's some truth to the maxim of beauty in confidence—all you need to make yourself more attractive is spray on your favorite scent.
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.
Whether you're a serious, sweating athlete or just need to recover after a night of drinking, chances are you've replenished your body's fluids with a sports drink at some point. Those electrolytes aren't the only thing entering your systems, though. Sports drinks are sugary, sweet, and loaded with calories—but there's a way you can still recharge your body without ingesting the unhealthy additives.
Researchers at the University of California, Riverside and the University of Michigan announced recently that they have developed a hack that works 92% of the time on Google's Gmail system on Android, as well as with the H&R Block app.
We tend to assume that eating is mostly a physical act, but the mind has so much to do with the choices we make.
An open bottle of wine can be dangerous. You intend to enjoy—nay, savor—a single glass, but then two episodes of Top Chef later, that sucker is empty. Now you have to go to work the next day with a wine hangover. What happened? Turns out there are some unconscious reasons you might be chugging more wine than you wanted. Never fear. Along with clenching your fists to make better food choices, there are some tricks you can use to moderate your wine intake. Researchers at Cornell University disc...
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.
Remember those horrible, soul-crushing studies from a few years back linking grilled meats with cancer? Unfortunately, they're still true, but scientists have recently found that an unexpected ingredient can curb some of the harmful effects of high-temperature cooking.
Both professional and home cooks have been rinsing raw chicken and turkey before cooking it for what seems like forever. It's one of those divisive practices—either you do it or you don't, and people tend to be rather opinionated on their stances.
English can be difficult because few words are spelled phonetically, and every rule has exceptions. But you can become a champ in no time by memorizing a few basic rules.
You need a break from gloomy coronavirus updates. We all do. The unrelenting stream of doom and negative news is both helpful in terms of keeping ourselves and our families safe, but it also has the unfortunate effect of increasing our anxiety. When will this end? How bad will it get? Is there reason to be hopeful?
Just like Apple and Google, Facebook has been working to develop computer vision shortcuts designed to give mobile apps augmented reality superpowers.
