The Winogradsky column, invented by Sergei Winogradsky, is a device for culturing a large diversity of microorganisms. Pond mud and water are mixed into a column using carbon sources like newspapers and sulfur sources like egg yolks. Left in the sun for a few months, the column becomes a colony rich with microorganisms, bacteria, cyanobacteria, and algae. In this video, scientist Karen Dodson shows you how to make your own.
Water makes up about 60% of your body weight. Whether you like it plain, flavored, bubbly, or in beverages or food, we all need water daily to avoid dehydration and stay healthy. For communities in need of clean drinking water, new research using bacteria may offer a simplified, lower-cost method for boosting potable water supplies.
When the climate changes, so do all the things that rely on the climate, including people, plants, and pathogens. A European study recently took a broad look at what kind of microorganisms are most likely to be affected as climate change heats, cools, dries, and wets the world around us.
Michelle Phan presents this tutorial on how to take a tomato and turn it into an invigorating scrub.
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.
Check out this video tutorial on how to streak an agar plate. What's an agar plate? Well, an agar plate is a sterile Petri dish that contains a growth medium (typically agar plus nutrients) used to culture microorganisms. Selective growth compounds may also be added to the media, such as antibiotics.
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?
When a dead body is discovered, finding out when the person died is just as important as finding out how the person died. Determining the time of death has always involved lots of complicated scientific detective work and less-than-reliable methods. However, a study by Nathan H. Lents, a molecular biologist at the John Jay College of Criminal Justice in New York, is the first of its kind to show how microbes colonize a body's ears and nose after death.
Frozen meat is a saving grace for weeknight meals. Whenever I crave a certain protein, all I need to do is defrost it. Sometimes, I don't even need to defrost it in order to use it.
You've heard the old saying, "When life gives you lemons, make lemonade." Well, the same goes true for snow. When Mother Nature dumps loads of the white stuff onto your neighborhood, then make the most of it with treats like maple snow candy, snow ice cream, and snow cocktails.

An inflamed throat is often the first sign that you're getting sick. Help nip it in the bud with a few simple tricks.
Everybody into the pool! Or the ocean! But not before you take measures to prevent your hair from getting fried.
All fields of study have their own language. For people interested in learning about microbes, the language can sometimes be downright difficult — but it doesn't need to be. From antibiotics to xerophiles, we have you covered in an easy-to-understand glossary.
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.
You just sat down, coffee in hand, and the day is ready to start. Now that you have taken a few sips, let me pose a question: What is living in that coffeemaker of yours? The answer might make you dump that coffee down the drain pronto.
Learn how to choose an indoor plant. You don’t need a green thumb to have houseplants that flourish; you just need to know which ones will thrive in your home.
Everything from disposed of drugs to hormones and disease-causing bacteria — anything that is rinsed or flushed down the drain — can contaminate wastewater.
Look no further than Flint, Michigan, to discover the serious consequences of contaminated drinking water. Around the world, water polluted by pathogens and toxins sickens people or cuts them off from safe drinking water. Looking for a solution, researchers created tiny, swimming robots that pack a powerful punch against waterborne pathogens.
A bacterium which triggers respiratory disease has been detected in the water systems of two Pennsylvania nursing facilities.
It won't come as a surprise to hear that your cell phone, tablet, and laptop are loaded with bacteria and other organic material. While most of these bacteria are harmless, there are good reasons to reduce the capability of your mobile devices to infect you—or other people.
Listeria monocytogenes bacteria don't play fair. Healthy people can usually handle the food-borne infection, but the bacterial infection hits pregnant women, fetuses and cancer patients very hard. Interestingly, a new study found that other bacteria may help prevent Listeria infections in those people.
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.
The Great Barrier Reef in Australia is the largest living system on the planet. Yet more than 90% of the reef is bleaching because of the loss of a tiny algae that lives within the coral.
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.
Just what are probiotics and why are they so good for you? Probiotics are "viable microorganisms" that can confer lots and lots of health benefits if they reach your intestine while they're alive. You may have heard them described as "friendly bacteria."
As the fish farming industry struggles to become more environmentally friendly, it just gained another problem. Fish food loaded with antibiotic-resistant genes.
Think of the coolest, most unique way to create art that you can. Got it? Now think about creating that art out of living things.
After establishing itself as a leader among media companies in augmented reality in journalism over the course of 2018, The New York Times pulled back from the technology this year.
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.
That soil under your feet is not just dirt. It is teeming with life that may not change as fast as we would like when challenged by global warming.
The future of forests looks dreary in the face of a warming climate, but scientists are exploring the relationship between soil microbes and the ability of trees to move to higher altitudes, a key component of their survival.
While the United States, in general, doesn't have the worst overall pollution, the air quality can drastically change from one day to the next. If you're particularly sensitive to pollutants in the air, there are apps that show how clean or polluted the air is in your area, as well as in cities you plan on traveling to, but Apple's making those apps less relevant with a new feature in Apple Maps.
How would you feel if the stethoscope used by your doctor to listen to your heart and lungs was teeming with potentially unfriendly bacteria?
A 'superbug' fungus is currently running riot in the hospitals of New York and New Jersey. This outbreak of Candida auris has contributed to 17 deaths in NYC, according to recent reports.
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.
Kale is the new baby spinach: it's taken over salads everywhere, and for good reason. This nutrient-dense vegetable is a member of the brassica family, which also includes cabbage, broccoli, and watercress. Recent studies show that people who eat more brassicas tend to have less cancer. Not only that, but kale and other brassicas can actually clear air pollutants from your body.
Every state has begun reopening in some capacity. While there are important steps for everyone to get back to work and begin socializing, precautions will be in place for some time, especially with an expected second wave coming this fall. The virus is not over.
This is a tale about microbes, a man who became a hermit, and the parchment that carries both of their stories.
Not all bacteria in the eyes cause infection. A group of researchers from the National Eye Institue has shown that not only is there a population of bacteria on the eyes that reside there but they perform an important function. They help activate the immune system to get rid of bad, potentially infection-causing — pathogenic — bacteria there.
