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: 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: 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: 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: 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.
How Epidemics Happen: The Terrifying Reality of Superspreaders
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?
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: 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: 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: 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.
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: 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.
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: 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: 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: 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: 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.
