Encyclopedia

Tardigrades, also known colloquially as water bears, or moss piglets), are water-dwelling, eight-legged, segmented micro-animals. They have been found everywhere: from mountain tops to the deep sea and mud volcanoes; from tropical rain forests to the Antarctic. Tardigrades are one of the most resilient known animals, with individual species able to survive extreme conditions that would be rapidly fatal to nearly all other known life forms, such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation. About 1,150 known species form the phylum Tardigrada, a part of the superphylum Ecdysozoa. The group includes fossils dating from 530 million years ago, in the Cambrian period. — Wikipedia

Science

Microbiology is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. 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 the 16S rRNA gene sequence used for bacteria identification. — Wikipedia

Using the principles of evolution to defeat cancer
on November 27, 2023 at 5:44 pm
November 24 marked 164 years since the publication of Charles Darwin's revolutionary "On the Origin of Species," one of the most influential scientific books ever written. In acknowledgement, 24 November is known as "Evolution Day" or the quirkier titled "All Our Uncles are Monkeys Day." The Institute of Cancer Research feels bound to commemorate this important work that challenged, and eventually transformed, our understanding of the natural world.

They're found on Mount Everest, in the deep seas, aboard the International Space Station and thousands of them have even crash landed and been spilled onto the moon. The microscopic water bear has a nearly unfathomable ability to survive in the most hostile environments. New research from the University of Copenhagen demonstrates that a wide variety of them also live in Denmark.

A team of biologists and Earth scientists from the U.S., China and South Korea has uncovered clues to explain the unique physiology of the tardigrade (also known as the water bear). In their paper published in Proceedings of the National Academy of Sciences, the group describes their analysis of tardigrade ancestors along with multiple tardigrade species.
