Random gene pulsing generates patterns of life

A team of Cambridge scientists working on the intersection between biology and computation has found that random gene activity helps patterns form during development of a model multicellular system.

Tuberculosis bacteria survive in amoebae found in soil

Scientists from the University of Surrey and University of Geneva have discovered that the bacterium which causes bovine TB can survive and grow in small, single-celled organisms found in soil and dung. It is believed that ...
