Space station mold survives high doses of ionizing radiation

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station's walls to prevent mold from becoming a health ...

Injection-molding wood powder for sustainable fabrication

Biomass materials such as wood are environmentally-friendly alternatives to fossil resources. As an example, wood is typically non-toxic and carbon neutral. Furthermore, wood can be produced in a sustainable manner by appropriate ...

Beewolves use a gas to preserve food

Scientists from the Universities of Regensburg and Mainz and the Max Planck Institute for Chemical Ecology discovered that the eggs of the European beewolf produce nitric oxide. The gas prevents the larvae's food from getting ...

How to develop affordable sensors using slime mold

Physarum polycephalum, which literally means "many-headed slime," is a slime mold that inhabits damp and dark habitats, such as decaying wood. Thanks to its ability to respond to stimuli such as light, chemicals and vibrations, ...

Molecular inhibition gets cells on the move

Researchers at Osaka University show how the mutual inhibition of two molecules results in their localization at opposite ends of cells, acting as a trigger for the formation of appendages at one cell end that makes directional ...

Mold

Molds (or moulds; see spelling differences) are fungi that grow in the form of multicellular filaments called hyphae. Molds are not considered to be microbes but microscopic fungi that grow as single cells are called yeasts. A connected network of these tubular branching hyphae has multiple, genetically identical nuclei and is considered a single organism, referred to as a colony.

Molds do not form a specific taxonomic or phylogenetic grouping, but can be found in the divisions Zygomycota, Deuteromycota and Ascomycota. Some molds cause disease or food spoilage, others play an important role in biodegradation or in the production of various foods, beverages, antibiotics and enzymes.
