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: 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 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: 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.

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: 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.
