Encyclopedia

Microorganism, or microbe, is a microscopic organism, which may be single-celled or multicellular. Microorganisms include all unicellular organisms and so are extremely diverse. Of the three domains of life identified by Carl Woese, all of the Archaea and Bacteria are microorganisms. These were previously grouped together in the two domain system as Prokaryotes, the other being the Eukaryotes. The third domain Eukaryota includes all multicellular organisms and many unicellular protists and protozoans. Some protists are related to animals and some to green plants. Many of the multicellular organisms are microscopic, namely micro-animals, some fungi and some algae, but these are not discussed here.

They live in almost every habitat from the poles to the equator, deserts, geysers, rocks and the deep sea. Some are adapted to extremes such as very hot or very cold conditions, others to high pressure and a few such as Deinococcus radiodurans to high radiation environments. Microorganisms also make up the microbiota found in and on all multicellular organisms. A December 2017 report stated that 3.45-billion-year-old Australian rocks once contained microorganisms, the earliest direct evidence of life on Earth. — Wikipedia

Science

Microbiology is the study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, parasitology, mycology and bacteriology.

Eukaryotic microorganisms possess membrane-bound cell organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include eubacteria and archaebacteria. Microbiologists traditionally relied on culture, staining, and microscopy. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means.
Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example 16s rRNA gene sequence used for bacteria identification. — Wikipedia

    • Biologists shed new light on an old question
      on December 12, 2018 at 6:44 pm

      For nearly 100 years biologists have argued about how exactly natural selection can possibly work. If nature selects the individuals with the best genes then why aren't all organisms the same? What maintains the genetic variation that natural selection acts upon, the genetic variation that has ultimately led to the spectacular diversity of life on Earth today? Recent findings suggest that the answer could be sex. […]

      on December 12, 2018 at 6:44 pm

      Figuring out how bacteria bring in nutrients could point to ways of killing them without poison. More generally, this research could also reveal how small organisms cooperate by generating networks of flow patterns. […]

      They approach with the telltale sign -- a high-pitched whine. It's a warning that you are a mosquito's next meal. But that mosquito might carry a virus, and now the virus is in you. Now, with the help of state-of-the-art technology, researchers can see how a virus moves within a mosquito's body, which could lead to the prevention of mosquitoes transmitting diseases. […]

    • Stop sterilizing your dust
      on December 11, 2018 at 6:33 pm

      A new study has found that an antimicrobial chemical called triclosan is abundant in dust -- and linked to changes in its genetic makeup. The result is dust with organisms that could cause an antibiotic-resistant infection. […]

      Why do orally-administered drugs for diabetes work for some people but not others? According to researchers, bacteria that make up the gut microbiome may be the culprit. […]

      The ammonia oxidizing archaea, or Thaumarchaeota, are among the most abundant marine microorganisms. Yet, scientists are still discovering which factors allow them to thrive in the ocean. A research team from the Max Planck Institute for Marine Microbiology in Bremen and the University of Vienna was now able to show that marine Thaumarchaeota have a broader metabolism than previously thought. The results are published in the journal Nature Microbiology. […]

      on December 10, 2018 at 4:00 pm

      A well-accepted principle in the animal kingdom—from wasps to deer—is that creatures already occupying a habitat nearly always prevail over competitors from the same species that arrive later. Such infighting for the same territory may be deemed "wasteful" by nature. […]
