News: These Special Sewage Bacteria Can Turn Dirty Water into Energy
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.
News: Rising Tide of Dust in the US Could Mean Public Health Menace
Blowing dust and fungal spores are creating a public health problem that could be just a slice of what's to come with climate change.
News: Hold That Breath — Fungus Goes Airborne Easier Than We Thought
Add breathing in your house as another possible danger to your health. If your home is sick, it's possible you could get sick too.
News: Glowing Bacteria Can Help Locate Devastating Hidden Land Mines
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.
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: How Researchers Could Use Bacteria to Determine Time of Death
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.
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: 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: Exotic Diseases Spreading to Europe as Ticks & Mosquitoes Expand Their Habitats
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.
News: Say Goodbye to Almonds—Common Pesticide Additive in Orchards Linked to Honey Bee Colony Collapse
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.
News: Bacteria Turn Off Plant Genes to Help Parasites Destroy Billions of Dollars of Crops Every Year
Before you bite into that beautiful tomato in your garden, the tomato fruitworm, or the Colorado potato beetle, might have beat you to it.
News: Airlines' Reliance on Group Boarding Could Spread Pandemics
On the airplane, in the middle of cold and flu season, your seatmate is spewing, despite the clutch of tissues in their lap. Your proximity to an infectious person probably leaves you daydreaming (or is it a nightmare?) of pandemics and estimating how likely it is that this seatmate's viral or bacterial effusions will circulate throughout the plane and infect everyone on board.
News: Extreme Cave-Dwelling Bacteria Found to Be Resistant to Antibiotics
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.
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: 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.
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: 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.
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: This Paper-Thin Foldable Battery Is Powered by Bacteria
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
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.
