As a nature photographer I have to keep an eye sections of the magazine. out for signs – for example weather signs that create the per- fect conditions for shooting my photos. Has the night been cold and the morning windless enough to create the necessary fog in the forests in autumn? What do satellite pictures and the precipitation radar have to say? Will there be nice, fluffy clouds and a clear sunny evening that allow me to work with light in the landscape? When I am out in nature, I pay attention to internal signs. Moments that make me pause, situations that fascinate me because they appeal to me aesthetically and emotionally. Why do I find a situation beautiful? Why does it appeal to me? What is the essential element I want to capture? This raises the question of the right technique and realization to perfectly capture this specific motif and mood. The intended result of this process is not, however, to docu- ment but rather to interpret the experienced scene and thereby takes on a very personal dimension. THE PHOTOGRAPHER Sandra Bartocha is a nature photog- rapher and a specialist author as well as a project seminar leader. She grew up in Mecklenburg-Western Pomera- nia and fell in love with the striking landscape of the Baltic Sea, the for- ests, and lakes of this unique German federal state. Bartocha studied Media Studies, English Language and Literature, and Educational Studies at the University of Potsdam. She is chief editor of the magazine »Forum Naturfotografie«.

Omen The genome, or genetic material, of a living organism or virus is the entirety of material carriers of the herit- able information of a cell or virus particle: chromosomes, deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) in the case of RNA viruses, in which RNA (not DNA) is the carrier of information. In a more abstract sense, the genome represents the entirety of heritable information. Thanks to the rapid development of modern techniques, much progress has been achieved in genome analysis in recent years. It is estimated that about 20,000 research- ers worldwide are involved in decoding the human genome alone. On 4 February 2013, a press conference was held in Leicester, in which the definitive positive identification of the Richard III’s remains was announced. In Decem- ber 2014 the genetic facts were published in a paper by 18 authors, led by Turi King and Michael Hofreiter. They would have liked to finish the entire project by the time the remains of Richard III were reburied as part of a one- week ceremony in Leicester in late March 2015. “But that was not possible. We are planning to have the genome completely analyzed by the end of the year – including any genetic defects,” Michael Hofreiter explains. A total of €50,000 has been earmarked for the project. “The costs of such analyses are much lower these days than they used to be. The first genome sequence extracted from fossils, the Neandertal genome, had a budget of €5 million. And now, just five years later, the same can be done for €10,000. Since we want to considerably improve quality, we have budgeted €50,000 for Richard III to get a high-quality genome that offers all sorts of answers.” The bone dust has almost been used up. What was left was returned to Leicester, where it was buried with the remains of Richard III. Michael Hofreiter could not attend, for time reasons. He would also like to see Analyzing DNA in the “ the performance of Richard III at the Potsdam laboratory.

Does Michael Hofreiter feel drawn to including any genetic mortality in his spare time, too? “No,” defects. ” he says cheerfully.

In his early days, he worked in the labora- tory; these days he spends most of his time in front of his computer writing manuscripts and applications for third-party funding.

Painting by the Rio Negro, crossed the Andes Mountains and climbed the Friedrich Georg Weitsch, 1810. Chimborazo volcano, and trekked through Mexico to the Unit- ed States, where they met President Thomas Jefferson. Hum- boldt recorded his observations in his “American Travel Dia- ries”, which were acquired by the Prussian Cultural Heritage Foundation in the autumn of 2013. Since early 2014, a group of experts led by Prof. Dr. Ottmar Ette has been researching the diaries in the sub-project “Genealogy, Chronology and Episte- mology”. The objective is to look back on and reappraise the untapped quantity and breadth of Humboldt’s observations. A second sub-project, “Preservation, Contextualization and Digi- talization”, at Berlin’s State Library is dedicated to preserving and digitalizing Humboldt’s scientific heritage. Humboldt feared disappearing: vanishing off the face of the earth, drowning or being buried under masses of snow. Not only for his own sake, but also out of fear of of knowledge.

Ironi- cally Phaedrus contradicted this metaphor: “I have followed [Aesop] and have made the path a road.” For Gärtner, a felicitous pun: “The irony reminds me of Monty Python,” she says, laughing, “when the crowd in the movie Life of Brian shouts, ‘Yes, we are all individu- als’ and one person interjects: ‘I’m not.’” Gärtner is proficient not only in Latin and Ancient Greek but also Hebrew. She acquired the Hebraicum on her own initiative at school in a “Hebrew study group”. “Over two years, three of us met at our reli- gion teacher’s house, where we had tea and cookies while preparing for the Hebraicum.” Her father was a professor of classical philology in Heidelberg at the time, which is why Gärtner, born in Heidelberg, went to Freiburg after high school. “I could not study under my father,” she says.
