Highly safe biocontainment strategy hopes to encourage greater use of GMOs

Hiroshima University researchers believe their simple phosphite-based control method will convince legislators to get with the times Use of genetically modified organisms (GMOs) – microorganisms not found in the natural world but developed in labs for their beneficial characteristics – is a contentious issue. For while GMOs could greatly improve society in numerous ways – e.g. attacking diseased cells, digesting pollution, or increasing food production – their use is heavily restricted by decades-old legislation, for fear of what might happen should they escape into the environment. For researchers, aware of their potential, it is important to develop safety strategies to convince legislators they are safe for release. For this reason… Read more

A Conversation with Distinguished Professor Kazunori Imaizumi A Common Cause Inside the cells of animals and plants is a folded, flattened tube of membranes piled on top of themselves. Studded along portions of the inside of this tube are ribosomes, small organelles that turn messages from DNA into protein. The proteins and occasionally important fats, or lipids, travel through the tube, folded and finalized into their completed form as they go. The tube itself is the Endoplasmic Reticulum, referred to as “the ER” by scientists. If something goes awry within the ER, proteins and lipids can get backed-up, clogging the tube and causing cellular stress. Both the potential causes and… Read more
