We all want to change the world.

…but we also want a career.

As the new year rolls in and celebrations pass, we begin to wonder what lies ahead. For some of us this unexplored year brings excitement as well as insecurities that we might not be willing to admit. For most of us, however, we are in sync to the yearly rhythm of life, and neither look forward to the new year nor welcome it with fear. We welcome it as we would welcome any other day; with a gratefulness of being alive. The value of the individual is so often disregarded in our ever so growing population. To tackle the problems of the world we form collaborations and networks including a little something of each individual personality, bringing forth diversity in both intellectual and emotional intelligence, and create a much stronger force to solve complex problems. But we mustn’t challenge the importance and power of the individual. After all, what motivates us, as individuals, to pursue these projects can be a combination of selfishness and aspiration to make a difference to a world that needs much of it.

What’s C4 photosynthesis?

Energy conversion in eukaryotes is strictly regulated.  In C4 plants, solar energy is converted to chemical energy, driving the carbon fixation engine of C4 photosynthesis—a complex network of finely tuned biochemical reactions, tightly regulated transport networks and underlying regulatory mechanisms [1].  It evolved from the classical C3 pathway, which solely uses ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) as the primary carboxylase for CO2 fixation [2].  During C4 photosynthesis (Fig. 1), CO2 is initially fixed by phosphoenolpyruvate carboxylase (PEPC) in mesophyll cells producing a four-carbon compound that is subsequently transported and decarboxylated in bundle sheath cells, concentrating CO2 around Rubisco, thus maintaining a favourable concentration of CO2 for suppressing rates of photorespiration [3]
