Summary[edit] Description: English: An international team of scientists has found that a strange type of bacteria can turn light into fuel in incredibly dim environments. Similar bacteria could someday help humans colonize Mars and expand our search for life on other planets, researchers said in a statement released with the new work. Organisms called cyanobacteria absorb sunlight to create energy, releasing oxygen in the process. But until now, researchers thought these bacteria could absorb only specific, higher-energy wavelengths of light. The new work reveals that at least one species of cyanobacteria, called Chroococcidiopsis thermalis — which lives in some of the world's most extreme environments — can absorb redder (less energetic) wavelengths of light, thus allowing it to thrive in dark conditions, such as deep underwater in hot springs. [Extreme Life on Earth: 8 Bizarre Creatures] "This work redefines the minimum energy needed in light to drive photosynthesis," Jennifer Morton, a researcher at Australian National University (ANU) and a co-author of the new work, said in the statement. "This type of photosynthesis may well be happening in your garden, under a rock." (In fact, a related species has even been found living inside rocks in the desert.) When grown in far-red light, this cyanobacteria, called Chroococcidiopsis thermalis, can still photosynthesize where others falter. Credit: T. Darienko/CC BY-SA 4.0.

Summary[edit] Description: English: The spirochete is a form of bacteria that results in lyme disease. It is characterized by its spiral formation. In addition to its spring-like shape, a spirochetal bacteria has filaments on the outside of its protoplasma. These filaments allow the bacteria to move while continuously rotating in place. Such placement of the flagella on a spirochete makes it easier for it to move throughout the bloodstream. Spirochetal bacteria also have the ability to cloak themselves within the bilayer of a cell, thereby avoiding detection from the immune system. This form of evasion makes it possible for a spirochete to remain dormant for long periods of time (by invading intracellular spaces). Date: 29 May 2012. Source: Own work. Author: Cvolk12.

Summary[edit] Description: English: Snapshots of electron tomograms and models of free and intracellular bacteriophages infecting Methylomirabilis cells. Tomogram (A) and model (B) of an infected Methylomirabilis cell. Most bacteriophages have the capsid (blue) assembled around the electron dense core (green). Some bacteriophages are still in the process of assembly and only consist of the electron dense core (pink). The cell is swollen and the cytoplasmic membrane (dark blue) is broken at many places (arrows). The cell wall (yellow) is still intact. All green electron dense cores were surrounded by a capsid, but not all capsids were modeled for reasons of clarity. Tomogram (C) and isosurface density model (D) of two free bacteriophages showing the icosahedral capsid (blue) and electron dense core (yellow). Tomogram (E) and Chimera model (F) showing two free bacteriophages. The electron dense core is enclosed by a putative membrane (arrows). Date: 8 November 2016.
