The Portuguese were fond of sailing, and their early nautical explorations initially connected the isolated continents into a whole. It is precisely because of this that Portugal’s world cultural heritage also has a strong integration of Europe, Asia and Africa. The author used the opportunity of a study tour in Europe to visit 11 cultural heritage sites located in various parts of Portugal in half a month, and personally experienced the early collision of Eastern and Western civilizations under the influence of the “Maritime Silk Road”.   Lisbon: From here to…

      A turtle beetle in the tropical rainforest of Panama has a pupa covered with a white, waxy substance. Scientists once believed that the substance was the secretion of tortoise beetles. Until 2020, scientists from a German Institute of Biology discovered that this white substance would actually grow in a petri dish. That means it’s not a discharge. So what exactly is it? research doesn’t stop   Through scanning electron microscope observation and gene sequencing, scientists discovered that this layer of white substance was actually a plant pathogen – Fusarium oxysporum (a white filamentous fungus). Although the fungus can be detected throughout the tortoise beetle’s life cycle, the scientists focused on the…
