"This book shares the story of Adel H., an Egyptologist, who, as a sixteen-year-old boy, was trapped for days under the Step Pyramid of Saqqara. Based on conversations with Adel H., the author tells of the boy's search for a way out of the underground world, how the boy roams passageways and chambers and sees what he calls 'impossible' things of which the professional world is completely unaware. Adel experiences uncanny events, a mixture of spirit realm and reality, that is described here for the first time. 'The story of Egypt,' Adel says, 'has two sides - the official one and the unknown one.'"-- "Bestselling author Erich von Däniken shares the story of a 16-year-old grave-diver who discovered a mysterious labyrinth of the old kings under one of the pyramids of Saqqara. In this book, Erich von Däniken shares the story of his friend Adel H., an Egyptologist, who, as a 16-year-old boy, was trapped for days under the Step Pyramid of Saqqara. Based on his conversations with Adel H., he retells the boy's search for a way out of the underground world, how the boy roamed passageways and chambers and saw what he calls "impossible" things of which the professional world is completely unaware. Adel experienced uncanny events, a mixture of spirit realm and reality, which is described here for the first time. "The story of Egypt," Adel says, "has two sides-the official one and the unknown one." It is secrets like the sights and events Adel experiences underground that von Däniken refers to throughout this book. Von Däniken shows that the Great Pyramid of Giza is nothing but a huge library created for the people of the future. He proves his claim through quotes from the few ancient works that still survive. Who actually had an interest for millennia in destroying knowledge/books? It's not about a few thousand, but about millions of books. Von Däniken documents the fanatical destructive rage of the people and means: If we would only have one ten-thousandth of the former writings, human prehistory would have to be completely rewritten. And where are the lost labyrinths? The one of Crete and the gigantic labyrinth of Egypt, of which all ancient historians reported? Against the background of these revelations, von Däniken turns the spot on to another focus of his book. A paradigm shift in the question of extraterrestrial life: "The gods have already come back. They came down again. They are currently orbiting our planet!""--

Bacillus thuringiensis (Bt)-based products are the most successful microbial insecticides to date. This entomopathogenic bacterium produces different kinds of proteins whose specific toxicity has been shown against a wide range of insect orders, nematodes, mites, protozoa, and human cancer cells. Some of these proteins are accumulated in parasporal crystals during the sporulation phase (Cry and Cyt proteins), whereas other proteins are secreted in the vegetative phase of growth (Vip and Sip toxins). Currently, insecticidal proteins belonging to different groups (Cry and Vip3 proteins) are widely used to control insect pests and vectors both in formulated sprays and in transgenic crops (the so-called Bt crops). Despite the extensive use of these proteins in insect pest control, especially Cry and Vip3, their mode of action is not completely understood. The aim of this Special Issue was to gather information that could summarize (in the form of review papers) or expand (research papers) the knowledge of the structure and function of Bt proteins, as well as shed light on their mode of action, especially regarding the insect receptors. This subject has generated great interest, and this interest has been materialized into the 18 papers of important scientific value in the field (5 reviews and 13 research papers) that have been compiled in this issue.
