Scientists at University of Washington have attempted to improve upon previous population models developed by the United Nations and the Austrian Wittgenstein Centre by using different calculation techniques for two key factors – fertility and migration.
Researchers found that minerals from rocks deposited in karst aquifers during storms comes in two waves.
A study of burned and unburned cigarettes found that water chemistry and microbes living in Mediterranean beach sediments changed after 4 days of exposure to a cigarette filter.
Microbes on Earth have adapted to survive in some pretty extreme locations. The extreme dryness of deserts, high salinity in salt deposits, cold temperatures of glaciers, and even high pressures of the deep ocean don’t stop some life forms. Another READ MORE
Researchers found a hidden selenium cycle tied to manganese oxide minerals made by common soil fungi.
Can photosynthetic organisms help clean up contamination? New research from @DominiqueChaput, @biominerals, @RadicalMicrobe & authors studied manganese mineral formation by photosynthetic organisms living in a Mn polluted environment.
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
Sulfuric acid production by sulfur-oxidizing bacteria may be a solution to a long standing mining problem.
