Spiroplasma is a genus of pretty odd bacteria. Most bacteria can be classified as either Gram-positive or Gram-negative. That is, they’re either surrounded by a cell wall and plasma membrane ...
Fruit flies across North America are evolving at breakneck pace -- and it has nothing to do with their genes. Instead they've acquired a bacterial infection that protects against the sterilizing ...
Maternally inherited symbionts are common in arthropods and many have important roles in host adaptation. The observation that specific symbiont lineages infect distantly related host species implies ...
Bacteria of the Spiroplasma genus produce toxic, ribosome-inactivating proteins (RIPs) that appear to protect their symbiotic host flies against parasitic wasps. Bacteria of the Spiroplasma genus ...
An endosymbiotic bacterium, Spiroplasma, specifically kills the males of its fruit-fly host (Drosophila). This has perplexed biologists since the 1950's, but scientists have now solved the mystery by ...
Bacteria of the genus Spiroplasma are widely found in plants and arthropods. Some of the maternally transmitted Spiroplasma endosymbionts in arthropods are known to kill young male hosts (male killing ...
Michael Phelps, one of the greatest swimmers of all time, propels himself forward by hurling water behind his body. If he were the size of a bacterium, though, that strategy wouldn’t make much of a ...
Osaka Metropolitan University researchers have made the mobile lifeforms that have the smallest genome so far. They introduced seven proteins, thought to let Spiroplama bacteria swim by spiraling, ...
The “kinky” motion of a primitive spiral-shaped bacterium swimming could help design efficient micromachines, suggests a new modelling study. The motion of Spiroplasma swimming through fluid by ...
