We all must travel at some point in our lives.  Whether that is short distance to and from school or work, or long distance like going on holiday.  In fact, migration has been an important part of human evolution and enabled the spreading of genes—the principle of genetics.   But travel, in which ever context, takes careful planning and assessment.  While travel may pose some risks, the results are rewarding.  Much like species that risk everything at a chance to mate, opening our travel networks, ensures the well-being and survival of our species.

PLANT SCIENCE

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]

Shaping the Future

There is a special relationship between art and technology that has impacted the way that we live, think and envision what the future may bring. Pioneer science fiction writers such as Jules Verne, H. G. Wells, and Isaac Asimov, to name a few, introduced ideas that were well beyond their time, fuelled by their experience, passion for science and ability to artistically link fact to fiction. Although science fiction writers often paint scenarios that go beyond the reachable scope of science in a given era, their works are written like dreams of scientific capabilities and adventures. Film adaptations bring these novels to life and artistic interpretation takes the fiction into a new dimension.
