How does the ‘brain’ of a living cell work, allowing an organism to function and thrive in changing and unfavourable environments?

Queensland University of Technology (QUT) researcher Dr Robyn Araujo has developed new mathematics to solve a longstanding mystery of how the incredibly complex biological networks within cells can adapt and reset themselves after exposure to a new stimulus.

Her findings, published in Nature Communications, provide a new level of understanding of cellular communication and cellular ‘cognition’, and have potential application in a variety of areas, including new targeted cancer therapies and drug resistance.

Dr Araujo, a lecturer in applied and computational mathematics in QUT’s Science and Engineering Faculty, said that while we know a great deal about gene sequences, we have had extremely limited insight into how the proteins encoded by these genes work together as an integrated network – until now.

“Proteins form unfathomably complex networks of chemical reactions that allow cells to communicate and to ‘think’ – essentially giving the cell
