A new camera setup can record three-dimensional movies with a single pixel. Moreover, the technique can obtain images outside the visible spectrum and even through tissues. The Kobe University development thus opens the door to holographic video microscopy. Holograms are not only used as fun-to-look-at safety stickers on credit cards, electronic products or banknotes; they have scientific applications in sensors and in microscopy as well. Traditionally, holograms require a laser for recording, but more recently, techniques that can record holograms with ambient light or light emanating from ...

Two important concepts in evolutionary biology, mutualism and altruism, were first made famous by the colorful anarchist prince Peter Kropotkin. He argued that cooperation could be an equally powerful driver of evolution as competition. Crucially, he was inspired by his youth as a geographer in the Russian Far East, where he observed how in particular the harsh climate favored cooperation, both within and between species. Now, researchers have shown that previously unknown apparent mutualisms allow biodiversity to flourish to ...

Plants that reproduce exclusively by self-pollination arise from populations with extremely low diversity to begin with. The Kobe University research not only adds a facet to possible evolutionary strategies, but also lends weight to Darwin’s suspicion that this strategy might be a path to extinction. Charles Darwin once remarked, “It is hardly an exaggeration to say that Nature tells us, in the most emphatic manner, that she abhors perpetual self-fertilization.” And yet, Kobe University botanist SUETSUGU Kenji knows of a few islands in Japan where orchids ...
