Based on new DNA results, the researchers were able to provide better classification of cyanobacteria.
Sort of like a fossilized microbial lasagna, fossils called “stromatolites” are formed when layered communities of different types of bacteria trap sand, dirt, and debris in their structure over time. Stromatolites are found in rocks as old as 3.5 billion years, and containing the planet’s earliest life forms.
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.
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
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
Sulfuric acid production by sulfur-oxidizing bacteria may be a solution to a long standing mining problem.
Our coral reef ecosystems, often called “underwater rainforests,” are quickly changing. Coral reefs are elaborate and complex ecosystems and even though they make up only a small fraction of the ocean, they contain 25% of all marine life. Reefs are READ MORE
Antibiotic resistance is a major public health crisis worldwide as bacteria develop the ability to defend themselves against many, sometimes all, of the antibiotics we have at our disposal. Infections caused by these bacteria are often life-threatening. In order to READ MORE
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
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
