Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.
Unfortunately, the very places we go to receive health care put us at risk for becoming infected with superbugs, bacteria exposed to so many antibiotics that they have become immune to their effects. Clostridium difficile (C. diff) is one such bacteria. It causes inflammation of the colon and rampant diarrhea that can have life-threatening consequences. Part of its virulence lies in the tough spores formed by the bacteria. They are responsible for starting infections in the colon and for spre...
The growing list of dangerous antibiotic resistant organisms has just acquired three new members. Researchers have discovered three new species of Klebsiella bacteria, all of which can cause life-threatening infections and have genes that make them resistant to commonly used antibiotics.
The intestinal parasite Cyclospora cayetanensis has a dramatically increased infection rate this summer, and the source is still unknown, the CDC advised today. 2017 is a good year for Cyclospora looking for homes to start their families and a bad year for those of us who don't like food-stealing tenants living in our bodies.
When you have an infection, a doctor prescribes antibiotics to make the bacteria that causes it disappear. Sounds like a good idea, but the disappearance of microorganisms that have inhabited humans for millennia could be driving rising numbers of serious illness and debilitating conditions.
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.
Antibiotics are one of our main weapons against infections. The problem is that many bacteria are becoming resistant to most of the antibiotics we use to treat them, and those 'superbugs' have created an urgent threat to our global health. A research group found a new way to hit a well known bacterial target and have developed a drug to hit it.
New research explores how the bacteria on the penis can leave men more susceptible to infection with HIV.
Flu vaccines can help prevent us from getting or suffering the most severe effects of the flu. But, each vaccine only protects us from three different strains of the flu. If we don't have a vaccine against all types of flu, it leaves us open for an epidemic with a flu virus we didn't expect.
With a death rate of one in five, sepsis is a fast-moving medical nightmare. New testing methods might improve your odds of survival if this infection ever hits you.
Montezuma's revenge, the runs, the trots, or just diarrhea — everyone gets it sooner or later. What exactly is diarrhea good for, if anything?
Some types of bacterial infections are notoriously tough to treat — and it's not all due to antibiotic resistance. The bacteria themselves are rugged and hard to penetrate with drugs.
Update 6/20/17: Olixar, a smartphone case manufacturer, has released images of an iPhone 8 case design. While at first glance this might seem to confirm the iPhone 8's final design, 9to5 Mac reports that Olixar admits they produced these renders based on "information and schematics they've acquired through their factories and contacts in the far east."
The Centers for Disease Control and Prevention estimated that there were 212 million cases of malaria across the world in 2015, and 429,000 of those people died — mostly children living in Africa. Preventing and treating those infections has been a challenging world priority. That makes a new malaria drug discovery — published in Science Translational Medicine — incredibly important.
While at work, you notice your gloves changing color, and you know immediately that you've come in contact with dangerous chemicals. Bandages on a patient signal the presence of unseen, drug-resistant microbes. These are ideas that might have once seemed futuristic but are becoming a reality as researchers move forward with technology to use living bacteria in cloth to detect pathogens, pollutants, and particulates that endanger our lives.
Viral infections have been the focus of attention in the development of autoimmune diseases—diseases where the body's immune system reacts to the body's own cells—because they trigger the immune system into action.
An advance in the race to stop birth defects caused by Zika-infected mothers has been made by a team of researchers from Rensselaer Polytechnic Institute in Troy, New York. They have identified the process Zika uses to gain entry into the placenta, and published their findings in the journal Biochemistry.
There could be a fresh outbreak of the Zika virus in the Americas as the weather heats up and the mosquito population blooms.
Call them what you will—moss piglets, water bears, or by their real name, tardigrade—but these intriguing tiny creatures can come back from the brink of death. They can survive boiling, deep freezing, UV radiation, completely drying out, and even a trip to space—without the benefit of being in a spacecraft.
A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the drug-resistance process.
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.
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.
As we slowly approach its January 3 start date, CES 2017 seems to be shaping up to be an exciting year for smart glasses as well as augmented and mixed reality.
Google's new Project Fi cellular carrier has been making waves across the mobile industry, so we decided to put it to the test against T-Mobile, one of the more established networks. For the actual testing, we slapped a SIM card from each carrier into two identical Pixel XL phones, which offer full compatibility with both networks.
This tutorial shows you how to create an intruder alarm that sends you text message alerts when motion is detected. This may sound complicated but I am pretty confident any beginner with electronics should be able to do this just fine. The range sensor senses motion and tells your Arduino board to send the text (SMS). So you can leave the intruder detector at home, connected to your network, and still receive the SMS alerts, no matter where you are, as long as you have cell phone service.
Video covering how to set up a Venn diagram. The video covers how to draw the diagram and then look at a set of data and place the data in the correct part of the Venn diagram. The sample problem is as follows.
Work, school, and everything in between keeps us pretty busy—so much so, that sometimes we run out of the house with our shirts on backwards, our headphones misplaced, and our computers running all day long.
Sitting at home alone on Friday night, I'm often in the mood to watch something more recent than the offerings on Netflix, Hulu, or Amazon Prime Video. And since the demise of video rental stores, that leaves me with browsing through the Redbox catalogue, then strolling down to the nearest 7-Eleven to pick up my movie.
The trick in the video is that the magnets are made of a conducting material and they connect the battery terminals to the copper wire, so the battery, magnets and copper wire make a circuit that generates a magnet field just in the vicinity of the battery. The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets.
You're hiking up a beautiful mountain when all of a sudden you remember it's your mother's birthday. You begin to panic—you forgot her birthday last year, and you know if you don't say something soon, you're as good as dead.
On June 12th, Samsung introduced their newest tablet series, the Galaxy Tab S line. These are the thinnest and lightest in Samsung's history, measuring in at only 6.6mm in width and weighing 465g (10.5-inch) and 294g (8.4-inch). Additionally, both have a WQXGA (2560x1600) Super AMOLED display giving these screens both richer and crisper colors.
I'm a textaholic. One of the problems with being a textaholic is that your device just can't keep up with you.
Sometimes you've got a head of lettuce that you want to eat but it lacks a certain youth. In other words, it's wilted and browning at the edges. Other times, you get to the grocery store near the end of day and the only lettuce or greens available look a little on the sad side. Never fear. You're not doomed to a meal of fast food or mouthfuls of soggy salad. You can easily revive those leaves and have something crisp, green, and delicious for your next meal, so don't dump it in the trash.
Mobile gaming, in case you haven't noticed, is huge. From the astronomical popularity of Candy Crush Saga, to the ease of using old school emulators, we love gaming on our mobile devices. The future is also bright, just take a look at the Oculus Rift, an immersive virtual world that just might change the way we view and play games.
Via Twitter, HTC, the Taiwanese device manufacturer, announced today that their barely 18 month old flagship phones will not see official updates for anything past Jellybean. HTC went on to elaborate, saying:
Adjusting the brightness on your Samsung Galaxy S3 can be a real pain sometimes. Each app you open may need a different amount of light to better optimize its use of the screen, and then you have to worry about it potentially eating up your battery life if it's too bright.
It's hot this summer, but it's not that easy to cool down when you're on the go. You can't take an air conditioner with you, and a handheld fan will just tire you out, so you'll need to find more creative ways to cool down when you're on the go. One of these ways is a DIY solar-powered fan baseball cap.
You can find a ton of live wallpapers for your Android device on Google Play, but the more alluring interactive ones are a harder to come by, which can bring your home screen to life using a few finger swipes and taps.
About a year ago, Abode decided to discontinue support for Flash on the Android platform. With its security concerns, it's understandable why some people would want to disable Flash on their devices, but there are still some things you can't do without it. Amazon Instant Videos is one thing you can't do, giving you nothing but a "Flash Player is not installed" warning.
