If a microbiologist is studying bacteria that bioremediate, or break down, toxic wastes and wants to know which specific genes are active when that bacterium is degrading, say, PCBs, he would likely use a tool called the DNA microarray.
Microarrays enable scientists to monitor the act... Read More
Microbiologists perform a wide range of jobs and activities, and the tools they use are just as diverse. The instruments and techniques that microbiologists use range from the simplest to the most complex.
Ant Farmers and Their Gardens of Fungi
It’s not clear precisely how and why some ancestral species of ant first took up fungus farming, but scientists have determined by genetic testing that it happened about 50 million years ago.
Major development projects are taking place in oceans across the globe all the time, enterprises that will provide shelter and food for a vast number of fish, mussels, urchins, and other marine life.
Collaborations on a Minute Scale
Over millions of years of evolution, we humans have worked out a mutually beneficial partnership with the microbes that came to inhabit our guts. In ... Read More
Fungi are eukaryotic organisms. This means that their DNA-containing chromosomes are enclosed within a nucleus inside their cells. (The chromosomes of bacteria and archaea are not walled off inside nuclei, making them prokaryotic organisms.)
Viruses are found on or in just about every material and environment on Earth from soil to water to air. They're basically found anywhere there are cells to infect. Viruses have evolved to infect every form of life, from animal to plant and from fungi to bacter... Read More
Lichens: When Fungi and Algae (or Cyanobacteria) Merged
Fungi feed themselves quite ably, absorbing nutrients from organic materials. Algae and cyanobacteria are also adept at providing for their own nutritional needs by turning sunlight into energy through photosynthesis.

The Partnerships That Led to Higher Life
If you could peer deep into one of the many cells in your body, you’d see little blobs, squiggles, and coils. These are the cel... Read More
In the deepest sea, where not a single photon of sunlight ever penetrates, life persists in eternal darkness, crowded around chemical- and lava-spewing fissures in the ocean’s floor. Life around these hydrothermal vents includes shrimp, crabs, and tall, slender tubeworms.... Read More
