Transmission electron microscopy (TEM) studies reveal that the spore walls of Echinostelium minutum, E. bisporum, E. arboreum, E. coelocephalum, E. corynophorum and Echinostelium sp. consist of two ...

After placing an ancient extreme Earth organism outside of the ISS for nine months, scientists were shocked to find it was ...

Moss spores have just joined the short list of life forms proven to withstand the raw vacuum of space for months at a time, surviving unshielded on the exterior of the International Space Station and ...

Histochemical tests, light and electron microscopy have been used to investigate the structure of the dormant spore of Gigaspora margarita (Endogonaceae). There is a plug in the neck of the mature ...

Airborne DNA from decades-old filters shows mosses moving their life cycles earlier as warming disrupts northern seasons.

Researchers have tested protenemata, brood cells and sporophytes of Physcomitrium patens under simulated space environments, identifying spores as the most resilient, and subsequently exposed them to ...

When spore-forming bacteria, such as Bacillus or Clostridium, enter a state of starvation, they transform into a state of dormancy in order to survive. No other life form is as difficult to eliminate ...

Moss spores survived an extended stay on the outside of the ISS and remained capable of germinating once back on Earth. Their resilience to vacuum, extreme temperatures, and UV radiation surprised the ...

A seed consists of an embryo with a packet of nutrition (usually), all housed in a protective coat. They range in size from the dust-like seeds of orchids to coconuts. And they all trace their origin ...
