Everything from disposed of drugs to hormones and disease-causing bacteria — anything that is rinsed or flushed down the drain — can contaminate wastewater.
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.

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.
Just like all living organisms, lawns need the proper amount of food and water in order to survive. Not giving them enough can lead to a dead looking yard that is unpleasant to look at.
If you own an Apple iOS device (iPhone, iPod Touch, iPad) then you probably have the 4.3 firmware update by now. It's got some cool improvements, but as usual necessitates a new jailbreak. Enter Sn0wbreeze 2.3b1, the beta version of the jailbreak for the new iOS. It's in beta, so it's not perfectly stable, but this video will show you how to use it. You can see a written version of the guide and the necessary download links here.

Hospitals are places we go to get well, and we don't expect to get sick or sicker there. But a study from researchers at the Cleveland Clinic, Case Western Reserve University School of Medicine, and Cleveland VA Medical Center in Ohio found that hospital floors in patient rooms were frequently contaminated with healthcare-associated pathogens—often dangerous multi-drug resistant bacteria.
Fondant frills are magical cake trims that resemble frilly lace and pretty ruffles. On cakes and cupcakes, they can be used to adorn borders for an uber feminine touch, and are especially beautiful on wedding cakes.
Spooky Halloween parties necessitate a certain amount of creeptastic spider webs, but the cheap cottony stuff that comes in plastic bags at most retailers feel fake and have been overused over the last few years.
Gonorrhea infections reached a peak in 1975, then decreased until 2009, when infection rate started rising and has increased each year since. With the rise of antibiotic resistance, those numbers are only going to get worse — unless we find new treatments against the bacteria.
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.
Drug-resistant bacteria have made curing some infections challenging, if not nearly impossible. By 2050, it's estimated that 10 million people will be dying annually from infections with antibiotic-resistant organisms.
The evolution of our infection-fighting systems may have something to teach modern scientists. That's what a group from the University of Granada in Spain found when they studied a protein that's been around for over four billion years. Their work, by senior author José Sánchez-Ruiz and colleagues in the Department of Physical Chemistry, was published in the journal Cell Reports.
Every year, 100-200 people in the US contract leptospirosis, but usually 50% of the cases occur in Hawaii where outdoor adventurers are exposed to Leptospira bacteria found in freshwater ponds, waterfalls, streams, and mud. That's why it's so alarming that two people in the Bronx have been diagnosed with the disease and a 30-year-old man has died from it.
Life has many perils: parasites, predators, and pitfalls. Eventually, any organism will succumb, and if that organism has not first passed on its genes, those genes will face extinction.
Significant strides have been in the race to find antibiotics to treat superbug infections — those caused by bacteria resistant to the antibiotics used to treat them. Now, an international team of scientists has discovered a new antibiotic produced by a microbe found in Italian soil.
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.
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.
Scientists are constantly on the search for new organisms, species, and other types of life. A special group of these researchers, calling themselves "bioprospectors," dive deep into mines to find unique lifeforms with special properties not found anywhere else.
Looking for a quick workout to get that six pack you've always wanted? Just like the classic 8 Minute Abs workout, this simulated workout will show you the exercises to motivate you to get a ripped midsection in no time at all!
In this how-to video, you will learn how to indicate if tree damage has occurred due to a natural gas leak. In this example, a Mexican Elder tree has been damaged by the gas leak. You can tell by the brown leaves. The plastic around the soil has trapped the gas in the soil, cutting off the oxygen from the tree. The Indian Hawthorne in this example has also been damaged. There is some foliage burn on the leaves. The bush will have to be trimmed back in order to save it. There are several plant...
To shine light on the future of the relationship between humans and viruses, a team of researchers from the University of Oxford looked into the dim and distant past.
In this how to video, you will learn how to make your own compost heap. Compost is nature's own living fertilizer. It can be purchased at stores, but you can also make it yourself. This can be started in any weather and at any time of the year. Tree trimmings, grass clippings, food scraps, coffee grounds, saw dust, and even dryer lint can be used for compost. Any mix can be used. The critical ingredient is oxygen. Coarse and soft mixes should be used. Water is also important. You want living ...
Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.
Mitochondria are known as the powerhouses of our cells because they generate energy to power them. But they also play a key role in the death of cells when they're damaged, infected, stressed, no longer needed, or at the end of their life.
Some bacteria can already do it—generate electric current, that is—and those microbes are called "electrogenic." Now, thanks to the work of a research group from the University of California, Santa Barbara, we know how to easily turn non-electrogenic bacteria into electricity producers.
Organic fertilizer is based of natural occurring compounds instead of chemical based compounds. With healthy, natural soil, learn how your plants and the environment can thrive in this free gardening video series about how to use organic fertilizers on plants. The following clips illustrate:
Video: . Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an "extraterrestrial" or "alien" (or, to avoid confusion with the legal sense of "alien," a "space alien"). These as yet hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans. The possibility that viruses might exist extraterrestrially has also been proposed.
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.
You've packed your own lunch and can't wait to get to the little vacuum-sealed cup of dessert you brought along. You keep rummaging in the bottom of the bag, searching for the spoon you're certain you packed…except you didn't. Uh-oh.
Building a robot in real life is not an easy task, and not usually accomplishable unless you have a degree in electrical engineering. But building one virtually on your computer is something almost anyone can do, if you know what program to use.
