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.
The bacteria in our gut — a community called the gut microbiome — have been in the spotlight a lot lately. What we're learning about how our intestinal bacteria adapt and grow with our bodies could help athletes perform better, according to researchers starting a company focused on creating probiotics that mimic athletes' microbiomes.
A terrifying antibiotic-resistant superbug, one thought to only infect hospital patients, has made its debut in the real world. For the first time ever, the superbug carbapenem-resistant Enterobacteriaceae (CRE) infected six people who hadn't been in or around a hospital in at least a year, and researchers aren't sure how they got infected.
It’s called Urophagia—the art of consuming urine. There could be any number of reasons for having the desire to drink your own urine (or somebody else’s). There’s the so-called term “urine therapy,” which uses human urine as an alternative medicine. In urine therapy, or uropathy, it’s used therapeutically for various health, healing, and cosmetic purposes. There’s also those people who drink urine as sexual stimulation, where they want to share every part of each other. And then there’s the o...
Acne develops when pores become blocked with dead skin cells and oil. They usually disappear over time but sometimes they leave a scar. When those blemishes form white blood cells rush to the surface to help heal the area. But occasionally a scar forms. Popping and picking can send bacteria further into the skin and increase the blemish and it greatly increases the likelihood that a scar will appear. Nodules and cysts are more severe blemishes and have an increased likelihood of leaving scars...
Bacteria gets a bad rap. Most headlines focus on the danger and discomfort posed by pathogens like bacteria, but many of the bacteria that live on and in us are vital to our health. Many products out there, called probiotics, are sold with the implication that they're supporting these healthy bacteria that share our bodies — but do they actually work?
Are you looking for a little microbe magic? Think composting. Composting is a great way to reuse food and plant waste that you would otherwise throw into the trash, which would just end up in a landfill somewhere. During the composting cycle, microbes reduce this organic waste until it can be fed back into the soil as rich, crumbly compost. When returned to the soil, compost feeds plants and improves the nature of life underground. Sound like a great idea? It is — and it's easy.
Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.
Was Napoleon's death really due to stomach cancer, or was it arsenic poisoning? Some scientist believe the latter. Arsenic poisoning was a deadly weapon in that era, because it was undetectable when administered over a long period of time, making murder seem like natural causes. But if arsenic (As) is poisonous to most multicellular life, then what's with the newest NASA discovery?
You can use either an open or a closed container for your terrarium. Because there is no drainage hole in the container it's really important to have a false drainage system. So you can add river gravel or rocks to the bottom of the terrarium as a drainage level. Put about one inch of rocks in the bottom of the terrarium. Add a layer of charcoal on top of the rocks and it will help to keep the whole terrarium fresh. The charcoal will help keep mold and bacteria from growing in the terrarium. ...
The incidence of tuberculosis (TB) is dropping in the US, but the World Health Organization (WHO) considers it to be epidemic in the rest of the world — there were over 10 million new cases in 2016.
New research reveals how E. coli bacteria construct elaborate and effective tunnels to pump unwanted molecules like antibiotics and other toxins out of cells. The discovery could help us better understand how antibiotic resistance occurs and give us a leg-up to beat them at their own game.
It doesn't take a nutritionist to know that eating too much meat is not good for your body. From hormones added to the feed for cows and chickens to contamination from bacteria, it's a good idea to integrate lighter vegetable dishes into your diet on a regular basis.
This video shows how to wash a horse's sheath. The instructor notes that you do not want to wash the horse's sheath to often because certain good bacteria needs to exist in the horse's sheath. It is noted that you can use soap but his method of choice is to just use water to clean the sheath. This sort of sheath cleaning is only necessary with tame horses and must be done very carefully. The instructor notes that you can just let water run into the sheath and just let it remove any dirt. It i...
This video teaches the viewer how to cook 10-minute noodles. First, we are shown to slice an onion. Second, roughly chop some garlic. Heat up some oil in your skillet. While you're waiting, you can slice a pepper. Toss all the ingredients in and be sure to keep them moving in the skillet. Next, chop up some chicken. Flip the board over to prevent spreading bacteria, and then chop up some green beans. Toss the green beans into the skillet, along with any other chopped vegetables you choose. Co...
Learn how to make a "Resident Evil"-style Biohazard Virus with nothing except the brush tool and layer effects in Photoshop. Use adjustment layers to create extra grain and contrast to your made from scratch hi-res microscopic bacteria and learn more about those brush tool options you didn't know about.
In this video Debbie Witter gives tips on how to get rid of a stye. A stye is a painful little pimple on your eyelid that comes from a bacteria called staphylococcal, which is found in the nose. Children get styes often because they pick their noses and then rub their eyes. Frequent hand washing is the best way to keep from getting a stye. Other possible causes are a clogged pore or ingrown hair.
There is nothing like fresh vegetables from the garden. Dave Epstein shows us the secrets to planting peas.
John White of Southwest Yard and Garden along with Kitty Schafer teach you about bio-intensive gardening. Bio-intensive gardening is the combination of two techniques. Part of the technique involves composting top soil with other coarse organic material into a lasagna style mound. Add 2 inches of straw to the soil and spray with water. Add 2 inches of green material that you have collected from other area of your garden, such as bug eaten greens or specific greens for composting. Then add som...

Peach trees and other related plants are susceptible to the devastation caused by fire blight, a contagious bacterial disease. Once contracted, infected trees have to be burned to contain the disease and prevent spread to nearby trees. Increasing resistance to antibiotic treatment has sent scientists in search of alternative ways to deal with the bacteria and prevent its catastrophic damage.
Although their effectiveness is waning, antibiotics remain a front-line defense against many infections. However, new science reveals using the wrong antibiotic for an infection could makes things much worse.
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.
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.
The search is on to find antibiotics that will work against superbugs — bacteria that are rapidly becoming resistant to many drugs in our antibiotic arsenal.
In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.
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.
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.
The squiggly guys in this article's cover image are Propionibacterium acnes. These bacteria live in low-oxygen conditions at the base of hair follicles all over your body. They mind their own business, eating cellular debris and sebum, the oily stuff secreted by sebaceous glands that help keep things moisturized. Everybody has P. acnes bacteria—which are commonly blamed for causing acne—but researchers took a bigger view and discovered P. acnes may also play a part in keeping your skin clear.
Legionnaires' disease is named after 1976 outbreak in Philadelphia that sickened 221 people and killed 34. More often striking adults over the age of 50, the Centers for Disease Control and Prevention (CDC) recently reported two cases where newborns contracted the often fatal disease — at their moment of birth.
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.
As unappealing as it sounds, transplants with fecal material from healthy donors help treat tough Clostridium difficile gastrointestinal infections. Researchers credit the treatment's success to its ability to restore a healthy bacterial balance to the bowels, and new research has shown that the transplanted bacteria doesn't just do its job and leave. The good fecal bacteria and its benefits can persist for years.
A promising new antibiotic has been discovered in, of all things, another bacteria. Burkholderia bacteria live in diverse habitats, including soil, plants, and humans where they thrive by knocking out other microbes that compete with them for resources or threaten their existence. Scientists have discovered they accomplish this by producing a very effective antibiotic.
Have you ever wondered what makes a healthy vagina? Bacteria play an important role in vaginal health. If you've ever had your vaginal microbiome—the bacterial community that lives in your vagina—wiped out by taking antibiotics, you probably are well aware of that.
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.
Have you ever had a burning sensation when you urinate? Low fever, back pain, and maybe cloudy urine? Male or female, it could have been a urinary tract infection. If it lasted long enough, the chances are good you went to the doctor for help. For about 20% of women, standard testing for a UTI does not reveal the presence of infection-causing bacteria, even though bacteria may be causing their symptoms. Well, a new test may provide better answers.
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.
As many as 700 species of bacteria live on our teeth and in our mouth, and just like the microbiomes inhabiting other parts of our bodies, they change in response to diseases and other health conditions.
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...
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.
