It seems appropriate to finish this book with the equivalent of a dessert or aperitif, to send the reader off with a sense of satisfaction, satiation, and hopefully pleasure. I thought about polishing my crystal ball and trying to project into what food might look like in the future but, as the Nobel Prize-winning Danish physicist Niels Bohr once said, prediction is very difficult, especially when it is about the future. Futuristic predictions are of course notoriously unreliable, as can be seen by the fact that we should all surely have our personalized jet-packs by now. Interestingly, one theme that may have come through in this book is that the future of food, at least for the next few decades, is, to adapt a quote by the writer William Gibson, probably here already, but just not equally distributed. The progress of food science has happened sporadically and unevenly, as when Bert Hite showed that high pressures could preserve food a century before anyone figured out how to make that work in a practical sense, and when NASA was introducing innovations in food safety and packaging for space travel that years later have become common practice in our restaurant kitchens and on our supermarket shelves. The story of food science in the last century has been about taking all that we knew about the art, provenance, and processing of food in the prescientific era and underpinning anecdote with fact and understanding. I think that this great era of scientific study of food has answered the main questions, such that we understand broadly why most of the things we have observed since mankind emerged and started to eat things happen, and moreover how to control these to our greatest advantage. Many scientific phenomena relating to food are well described, in textbooks, websites, and a huge body of scientific papers, while of course leaving plenty of interesting questions and challenges for future generations of food scientists to explore.

AbstractESA and NASA are studying projects having a tremendous return on variable star research. Other national space agencies are also studying or developing projects of smaller costs but with impressive returns. The projects range from global Galactic surveys like the ESA mission GAIA which will give photometric time series for about 1 billion stars, to detailed pulsation-mode studies like the CNES mission COROT which could reach a photometric precision lower than 1 ppm. The presentation will emphasize the future astrometric, asteroseismological and planet detection missions.

AbstractSpace flight produces an extreme environment with unique stressors, but little is known about how our body responds to these stresses. While there are many intractable limitations for in-flight space research, some can be overcome by utilizing gene knockout-disease model mice. Here, we report how deletion of Nrf2, a master regulator of stress defense pathways, affects the health of mice transported for a stay in the International Space Station (ISS). After 31 days in the ISS, all flight mice returned safely to Earth. Transcriptome and metabolome analyses revealed that the stresses of space travel evoked ageing-like changes of plasma metabolites and activated the Nrf2 signaling pathway. Especially, Nrf2 was found to be important for maintaining homeostasis of white adipose tissues. This study opens approaches for future space research utilizing murine gene knockout-disease models, and provides insights into mitigating space-induced stresses that limit the further exploration of space by humans.

Despite extensive critical attention, Arthur C. Clarke’s distinctive science fiction has never been fully or properly understood. This study examines some of his lighthearted shorter works for the first time and explores how Clarke’s views regularly diverge from those of other science fiction writers. Clarke thought new inventions would likely bring more problems than benefits and suspected that human space travel would never extend beyond the solar system. He accepted that humanity would probably become extinct in the future or be transformed by evolution into unimaginable new forms. He anticipated that aliens would be genuinely alien in both their physiology and psychology. He perceived a deep bond between humanity and the oceans, perhaps stronger than any developing bond between humanity and space. Despite his lifelong atheism, he frequently pondered why humans developed religions, how they might abandon them, and why religions might endure in defiance of expectations. Finally, Clarke’s characters, often criticized as bland, actually are merely reticent, and the isolated lifestyles they adopt--remaining distant or alienated from their families and relying upon connections to broader communities and long-distance communication to ameliorate their solitude--not only reflect Clarke’s own personality, as a closeted homosexual and victim of a disability, but they also constitute his most important prediction, since increasing numbers of twenty-first-century citizens are now living in this manner.
