News: We've Finally Figured Out Why Some Mushrooms Glow
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.
Soil Science: How Microbes Make Compost to Feed the Soil
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.
News: Microbots to the Rescue! Swimming Bots Kill Bad Water Microbes
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.
News: Sponge Bacteria Clean Heavy Metals & Toxins Like Arsenic from Water, Saving Turtles & Humans Alike
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.
News: Scientists Turn Bacteria into Mini Cyborg Solar Panels
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.
News: How Livestock Farts Lead to a Warmer Climate
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.
News: How a Vaccine Could Protect Florida's Orange Trees
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.
News: Termite Guts May Hold the Key to More Efficient Biofuels
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.
How To: Here's How to Compost if You Are an Apartment Dweller
Being a city dweller does not mean you cannot save the planet — or your food scraps. Climate change and resource management are big issues. Composting in any size space is not only possible, but it gives you a chance to reduce greenhouse gasses and reuse food scraps. Right now, about 40% of all food in the US goes to the landfill. In addition to planning meals and using your food in creative ways to reduce the amount that goes to waste, you can compost.
News: Like Peaches? Protective Virus Could Save Millions of Dollars in Fruit from Fire Blight
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.
News: Soil Microbes Are Key to Understanding Climate Change on (& in) The Ground
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.
News: Melting Ice Sheets Are Releasing Toxins in Our Water — Bacteria Could Take Some of That Out of Play
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.
News: Another Reason to Wash Your Sheets—Deadly Hospital Fungus Linked to Moldy Linens
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.
News: A Beach Infected with Fecal Coliform Can Ruin Your Vacation, but Seagrasses Can Save the Day
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.
Deadlier When Hot: These Infections Are Likely to Get Worse as the Climate Changes
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.
News: Study Finds HIV Family of Viruses Far Older Than Civilization
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.
News: How El Niño—& Climate Change—Kill People with Virus Epidemics
Using mathematical modeling, researchers suggest weather and warming created the "perfect storm" that drove the Zika outbreak in 2016.
News: Latest Research Cements Link Between Climate Change & West Nile Outbreaks
A recent study underscores a connection between climate change and infectious disease, raising concerns about our quickly warming planet.
News: Unexpected Microbial Life in Glacial Clay Could Offer Antibiotic Solutions
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.
News: Sleeping with the Fishes — Decay in Wastewater Damages Aquatic Life
Everything from disposed of drugs to hormones and disease-causing bacteria — anything that is rinsed or flushed down the drain — can contaminate wastewater.
