In the multicellular soil bacterium Streptomyces coelicolor, some cells start producing lots of antibiotics after mutations delete big chunks of their genomes. Now a computer model has helped to ...

Cooperation is a classic solution to hostile environments that limit individual survival. In extreme cases this may lead to the evolution of new types of biological individuals (e.g., eusocial ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...

A new study shows that multicelled organisms like the metazoan daphnia (pictured) require a tenfold increase in energy compared with protists for their growth, maintenance and survival. The high cost ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

A new study led by researchers at Yale and McGill University reveals how fluctuations in the Earth’s oxygen levels over 700 million years ago may have set the stage for the diversification of ...

Algal cells that cheat are more vulnerable to stress. This trade-off could help explain the emergence of multicellular organisms, and what keeps cells in algae and cells in our bodies cooperating with ...

Life and death are traditionally viewed as opposites. However, the emergence of new multicellular life forms from the cells of a dead organism introduces a “third state” that lies beyond the ...

In multicellular organisms, there are three types of protein glycosylation. N-glycosylation, O-mannosylation and C-mannosylation. All of these processes take place in the endoplasmic reticulum, and in ...

Multicellular organisms are a mosaic of different cells, tissues, and systems, each with their own specific function and interactions with other cells within the organism and/or the larger environment ...
