For as long as 14,000 years, the First Nations people of the Heitsuk Nation have made their home along the Central Coast of the Canadian province of British Columbia. Among the territory's inlets, islands, rivers, and valleys lie a clay deposit on the north side of Kisameet Bay, near King Island. For as long as most can remember, the tribe has used the clay as medicine. Now science says microbes that live in that clay may have important antibacterial properties.
On July 20, 1969, humans set foot on the moon for the first time. But some say our microbes beat us there. With the Space Age came new questions about microscopic invaders from outer space and concern about where we are leaving our microbial footprints. The questions are even more relevant today.
A 6,000-year-old forest inhabitant awakens to find life in the forest around it in crisis. Plants, trees, animals, and birds are moving north to escape increasingly heated air, even as mass extinctions take place around the world. The inhabitant stirs and remembers it has lived this before and knows what to do.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
About a third of the methane released into the environment comes from the production and transport of natural gas. The gas leaks as it moves along the transport chain from gas wellheads to market.
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.
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.
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.
Everything from disposed of drugs to hormones and disease-causing bacteria — anything that is rinsed or flushed down the drain — can contaminate wastewater.
A new study casts real suspicion on the possibility of life on Mars. Why? It seems the surface of the planet may be downright uninhabitable for microbial life as we know it.
Just like your gastrointestinal tract, and the soil we walk on — a dust storm has a collection of bacteria, fungi, and viruses all its own called a "dust microbiome."
Earlier this year, NASA reported on findings that might point to water, and microbial life, on moons orbiting Jupiter and Saturn. Named Europa and Enceladus, those moons contain large oceans under their icy surfaces, which many speculate could hold microbial life.
The Deepwater Horizon oil spill that began on April 20, 2010, was the largest maritime oil spill in history. Killing 11 people and discharging 4.1 million barrels of oil and natural gas into the Gulf of Mexico, the event was an unparalleled personal, environmental, and business disaster. It was also the first major oil spill to take place in the deep ocean.
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.
One thousand feet under the ground, extremophile microbes that have not seen the light of day for four million years are giving up some fascinating facts to scientists who go the distance.
Citrus greening disease — caused by a bacteria spread by psyllid insects — is threatening to wipe out Florida's citrus crop. Researchers have identified a small protein found in a second bacteria living in the insects that helps bacteria causing citrus greening disease survive and spread. They believe the discovery could result in a spray that could potentially help save the trees from the bacterial invasion.
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.
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.
We've worked hard to reduce the flow of toxic chemicals into our waterways, which means no more DDT and other bad actors to pollute or destroy wildlife and our health. But one observation has been plaguing scientists for decades: Why are large quantities of one toxic chemical still found in the world's oceans?
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.
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.
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.
Termite poop and biofuels — what's the connection? New research into termites' intestinal comings and goings describes a process that may speed the development and lower the cost of fuels made from plant matter.
Devastating and deadly, land mines are a persistent threat in many areas of the world. Funding to clear regions of land mines has been decreasing, but new research may offer a less dangerous method of locating hidden, underground explosives by using glowing bacteria.
When it comes to global warming, most of us think of carbon dioxide emissions. While carbon dioxide is the most important greenhouse gas, carbon dioxide emissions have stayed constant for the last three years. On the other hand, methane, the second most important gas, has been steadily rising since 2007.
Growing populations and higher temperatures put pressure on world food supplies. Naturally occurring soil bacteria may save crops in drought-stressed areas, put more land into crop production, and produce more food.
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.
The beauty of southern Europe won't protect it from invasions of disease-carrying ticks and mosquitoes—in fact, the Mediterranean climate and landscape may be part of the reason the bloodsuckers are expanding there, bringing unique and terrifying diseases in their wake.
Arsenic occurs naturally in the environment, but it is also one of the most commonly found heavy metals in wastewater, deposited there by inappropriate disposal and arsenical pesticides, for example.
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.
We may not fully appreciate all the important roles wheat plays in our lives until it's gone—or at least, when it's in very short supply. What would a world be like without bread, cakes, cereal, pasta, or wheat beer? If the dire warnings about an impending stem rust fungus come to pass, we may know all too soon.
At a global security conference in Munich, philanthropist and businessman Bill Gates spoke about the next pandemic and a dire lack of global readiness. Here's how his statement could come true—and how to be ready when it does.
Six people have died from fungal infections in Pittsburgh hospitals since 2014—that fact is indisputable. The rest of the situation is much vaguer. A lawsuit has been filed against the hospitals on behalf of some of the deceased patients, alleging that moldy hospital linens are to blame. While the lawyers argue over who's at fault, let's look at how this could have happened.
Jostled in the airport, someone is coughing in line. The air looks empty but it is loaded with microbes that make their way into your body. You get sick. You give it to your family, and that's pretty much it. But what if you were so contagious that you spread it to your entire community and beyond?
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.
Exposed to hormones, pharmaceuticals, and other chemicals, the beautiful wild fish in Canada's Grand River have taken on some pretty odd characteristics—they're turning into females. A long-term study suggests using bacteria to manage polluted water could turn the tide for feminized fish.
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.
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.
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.
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.
The search for the causative agent of colony collapse—the mass die off of honey bees throughout the US and Europe—has escalated with increasing confusion lately. Everything from pesticides and stress to viruses and mites have been implicated, and some researchers think that many of these environmental factors work together to take down hives.
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.
