A study led by a northern Ontario scientist could lead to more insights into how humans and other living things think, and she used organisms (sinh vật) without brains (không có não) to come to her conclusions.

Nirosha Murugan, an assistant professor at Algoma University in Sault Ste. Marie, Ont., had research published this week in the journal, Advanced Materials. It was from a study she conducted while working as a postdoctoral scholar at Allen Discovery Centre at Tufts University in Massachusetts.

The study looked at organisms called Physarum polycephalum, known colloquially (thông tục) as slime mold (nấm nhầy). It normally grows on forest floors or humid forest areas.

Physarum polycephalum do not have brains, but Murugan's tests showed that it does make decisions (ra quyết định).

For the experiment the slime mold was put in petri dishes with a layer of gel. Clear glass discs of varying weights were placed at each end. Murugan says it took about 24-hours for the entire process, and for the first seven hours the physarum grew evenly in a ring shape (hình tròn).
