Chemical Landmark 2015
Die siebte Auszeichnung einer «Historischen Stätte der Chemie» geht an das erste chemische Institut der Universität Freiburg.
Im Jahr 1896 wurde eine als Zeughaus genutzte Waggonfabrik zum ersten Chemieinstitut ausgebaut. Das Gebäude zeugt von der Übergangszeit der Industrialisierung und somit vom Vormarsch der Naturwissenschaften und beherbergte zwischen 1896 und 1974 die chemischen Institute der Universiät Freiburg. Es wurde erfolgreich eine Kombination der deutschen und französischen Bildungs- und Forschungskulturen gelebt, was z. B. zur Entdeckung des Farbstoffe moleküls Phthalocyanin führte, welches auch heute noch in ca. 25 Prozent der organischen Pigmente verwendet wird. Die Verleihung des Chemical Landmark wird in diesem Jahr mit der jährlichen Fribourg Chaim Weizmann Lectureship kombiniert.

Fribourg Chaim Weizmann Lectureship
Chaim Weizmann erhielt im Jahre 1899 seinen Doktortitel in Chemie am oben genannten Chemieinstitut.
Der Preisträger 2015 ist der Nobelpreisträger Alan J. Heeger, der zum Thema «Creativity, Discovery and Risk – Nobel Prizes Past and Future» referieren wird.
Alan J. Heeger, Professor für Physik und Materialien an der University of California in Santa Barbara, erhielt im Jahr 2000, zusammen mit A. G. MacDiarmid und H. Shirakawa, den Nobelpreis in Chemie für die Entdeckung und Entwicklung leitfähiger Polymere. Er wird über die enge Verbindung zwischen Kreativität und Risikobereitschaft in der Wissen schaft reden. Anhand von Beispielen aus seinem Leben und vergangenen Nobelpreisen wird er die Kreativität von der Entdeckung unterscheiden. Er wird seine frühen Ergebnisse im Bereich leitfähiger Polymere zusammenfassen und dabei die Risiken in seiner Forschung veranschaulichen. Dann wird er über seine jetzigen wissenschaftlichen und unternehmerischen Aktivitäten erzählen, die von «Plastik»-Solarzellen, über flexible Polymer-Feldeffekttransistoren zu Biosensoren reichen.
Die «Platform Chemistry» der Akademie der Naturwissenschaften Schweiz (SCNAT), die Freiburger Chemische Gesellschaft (FCG) und die Universität Freiburg freuen sich, Sie zur Auszeichnung «Chemical Landmark 2015» und zur «Fribourg Chaim Weizmann Lecture 2015» nach Freiburg einzuladen.

Official Press Release, 7 October 2015
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2015 to
Tomas Lindahl,
Francis Crick Institute and Clare Hall Laboratory, Hertfordshire, UK
Paul Modrich,
Howard Hughes Medical Institute and Duke University School of Medicine, Durham, NC, USA
and
Aziz Sancar,
University of North Carolina, Chapel Hill, NC, USA
“for mechanistic studies of DNA repair"
The cells’ toolbox for DNA repair
The Nobel Prize in Chemistry 2015 is awarded to Tomas Lindahl, Paul Modrich and Aziz Sancar for having mapped, at a molecular level, how cells repair damaged DNA and safeguard the genetic information. Their work has provided fundamental knowledge of how a living cell functions and is, for instance, used for the development of new cancer treatments.
Each day our DNA is damaged by UV radiation, free radicals and other carcinogenic substances, but even without such external attacks, a DNA molecule is inherently unstable. Thousands of spontaneous changes to a cell’s genome occur on a daily basis. Furthermore, defects can also arise when DNA is copied during cell division, a process that occurs several million times every day in the human body.
The reason our genetic material does not disintegrate into complete chemical chaos is that a host of molecular systems continuously monitor and repair DNA. The Nobel Prize in Chemistry 2015 awards three pioneering scientists who have mapped how several of these repair systems function at a detailed molecular level.
In the early 1970s, scientists believed that DNA was an extremely stable molecule, but Tomas Lindahl demonstrated that DNA decays at a rate that ought to have made the development of life on Earth impossible. This insight led him to discover a molecular machinery, base excision repair, which constantly counteracts the collapse of our DNA.
Aziz Sancar has mapped nucleotide excision repair, the mechanism that cells use to repair UV damage to DNA. People born with defects in this repair system will develop skin cancer if they are exposed to sunlight. The cell also utilises nucleotide excision repair to correct defects caused by mutagenic substances, among other things.
Paul Modrich has demonstrated how the cell corrects errors that occur when DNA is replicated during cell division. This mechanism, mismatch repair, reduces the error frequency during DNA replication by about a thousandfold. Congenital defects in mismatch repair are known, for example, to cause a hereditary variant of colon cancer.
The Nobel Laureates in Chemistry 2015 have provided fundamental insights into how cells function, knowledge that can be used, for instance, in the development of new cancer treatments.

Who's Next? Nobel Prize in Chemistry 2015
The Nobel Prize in Chemistry will be announced on October 7, 2015.
The results so far suggest an American chemist in the organic field will win the 2015 Nobel Prize. The top three write-in suggestions are: Antoine Fécant, George M. Whitesides, and Omar M. Yaghi.
Looking at other predictions for the next Nobel Laureates, Thomson Reuters 2015 Citation Laureates for example suggests Carolyn R. Bertozzi, who contributed to bioorthogonal chemistry, or Emmanuelle Charpentier and Jennifer A. Doudna, who developed the CRISPR/cas 9 method for genome editing, have a good chance.
