Bacteria from the Black Sea Have an Unusual Diet A new species of bacterium was discovered that lives off manganese and sulfur instead of oxygen or carbon dioxide

Many organisms live by breathing in oxygen and breathing out carbon dioxide, and those that don’t often live by taking in carbon dioxide and releasing oxygen. However, did you know that these aren’t the only ways life can survive? Researchers recently discovered Sulfurimonas marinigri, a species of bacteria that survives by taking in sulfur and manganese instead of oxygen and carbon. This method of survival has long been theorized, but could never be proven until now.

Contaminants in groundwater can take over 20 years to break down But scientists have a method for removing the contaminants more quickly, using a underground barrier.

Have you ever driven past an old factory building and wondered what ever happened to the harsh chemicals that were used there? If you guessed that a lot of the chemicals ended up in the environment, you would be right. READ MORE

A Special Kind of Bacteria Lets Cement Fix Itself Mineral-forming bacteria that grow best in fast-flowing liquid may be the glue that researchers need to close cracks in underground cement.

Cement is one of those common building materials that you can find just about anywhere. When the cement starts to get cracked, fixing it is generally an easy task that involves widening the crack slightly before filling it with more READ MORE

Mining with acid-generating bacteria Sulfuric acid production by sulfur-oxidizing bacteria may be a solution to a long standing mining problem.

Parkinson’s Disease and Antioxidant Treatment A recent study highlights a promising potential therapy for the neurodegenerative disease

Parkinson’s disease currently affects over 10 million people worldwide, and in the United States approximately 60,000 people are diagnosed with the disease each year. It is a disease in which the brain cells, or neurons, that produce dopamine progressively die READ MORE

Can Fish Help Us Understand Why We Age? Fish that age rapidly and fish that live extremely long lives are different in terms of the compounds present in their blood.

What exactly causes aging at a molecular level? The answer to this question is important for understanding and potentially improving health and life itself.  In order to begin to answer this question, researchers at the Institute of Biomedical Chemistry in READ MORE

Oxygen, nitrogen, and what happens when biology gets involved How the Great Oxidation Event and photosynthesis created the nitrogen cycle we know today

When studying Earth’s past, researchers want to understand how nutrients like nitrogen cycled and the impact biology had on them. Scientists rely on ancient rock, soil, fossils, and marine sediment to understand the world that used to be.  Approximately 2.5 READ MORE

Heating Up the Microbial Soup: Warm Oceans May Benefit Cyanobacteria Cyanobacteria can grow better with limited nutrients if the water temperature is increased, but only to a certain extent.

The oceans are warming due to climate change and this will impact all oceanic life, from the smallest plankton to the largest tuna. The web of life in the ocean is complex, and so exactly which ecosystems will be affected READ MORE

Bacteria with Nanowires can Electrocute Metals Instead of Breathe Recycling Expensive and Toxic Metals with Bacteria

All life on Earth has to respire. For us this means inhaling oxygen to fuel our metabolism and exhaling waste gases like carbon dioxide. When we do this, we move the energy  from the food we eat to the oxygen READ MORE

“Hulk”-like microorganisms in soil can survive high levels of gamma radiation Scientists exposed soil microorganisms to low, medium, and high doses of gamma radiation to see who could survive

In the Marvel Universe, Bruce Banner exposed his body to high doses of gamma radiation during an experiment in his lab. The gamma radiation deformed Bruce’s DNA, so whenever he became angry, he could turn into the Hulk. In the READ MORE
