Classic biomolecules continue to surprise with unexpected reactivity

Written by

Biological hydrides like NADH and folates were identified by early biochemists for their importance in fermentation and hydrogen transfer and are today some of the most thoroughly studied biomolecules. Dr Michael Denk, Professor of Chemistry at the University of Guelph, PhD candidate Nicholas Milutinovic and PhD candidate Katherine Marczenko have been performing research which has shown that these old biomolecules […]

Proteomics reveals new possibilities in the fight against infection

Written by

The work of Dr Jennifer Geddes-McAlister at the University of Guelph investigates the interactions between hosts and pathogens to uncover new treatment options to combat infections. Her lab uses a range of techniques centered around proteomics, the study of proteins, to progress knowledge of fungal and bacterial infections in humans and agricultural crops. The results of this research can be […]

Understanding plant thermoregulation in the face of climate change

Written by

Plants possess the fascinating ability to control their body temperature. This physiological process is fundamental for the growth, reproduction, and survival of numerous species of plants. In the face of climate change, as temperatures increase and rainfall patterns become more variable, understanding the capability of plants to adapt to changing conditions is becoming critical. Prof Peter Kevan and colleagues at […]

Secrets of the stalk: Regulating plant temperature from the inside out

Written by

Have you ever questioned the reasoning behind hollow stems in some plants? When we think about it there are a surprising number of plants with this feature. A common misconception would be to believe it is solely for nutrient or water transport. In fact, the reality has much more to do with temperature regulation. Dr Peter Kevan from the University of Guelph […]
