Scientists used to think cysteine was required to manufacture itself. Turns out, it isn’t. In fact, cysteine slows down the manufacture of itself. Go figure!
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.
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
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
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
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
