Title: 3D core-collapse supernova modeling and applications to Cas A and other supernova remnants, Presentation in English
Date: Monday, 15 October 2018, 2:00 p.m.
Location: Carl-Bosch-Auditorium, Studio Villa Bosch, Schloss-Wolfsbrunnenweg 33, 69118 Heidelberg (Studio entrance between Villa Bosch and HITS)
Parking: Parking garage "Unter der Boschwiese" (free of charge)
Abstract:
First three-dimensional, first-principle simulations of core-collapse supernovae have become possible in the recent past. They demonstrate the basic viability of the neutrino-driven mechanism for powering the explosions of the majority of supernova progenitors. Although a number of open questions remain to be settled, the explosion models are now sufficiently mature to strive for detailed comparisons against observations, for example considering well studied, nearby supernovae and young supernova remnants. This talk will review our basic understanding of the explosion mechanism and report some results of such observational tests.

Title: Artificial Sensor Proteins for Applications in Basic Research and Medicine, Presentation in English
Date: Monday, 17 September 2018, 11:00 a.m.
Location: Carl-Bosch-Auditorium, Studio Villa Bosch, Schloss-Wolfsbrunnenweg 33, 69118 Heidelberg (Studio entrance between Villa Bosch and HITS)

Abstract:
Monitoring drug or metabolite concentrations at the point-of-care could improve the diagnosis and management of numerous diseases. Yet for most medically relevant molecules, such assays are not available. Using a combination of synthetic chemistry and protein engineering, we have generated light-emitting sensor proteins for use in paper-based assays. The analyte induces a change in the color of the emitted light, enabling its quantification using a digital camera. The approach makes numerous medically relevant molecules candidates for quantitative point-of-care assays, as shown for the anti-cancer drug methotrexate. Methotrexate serum levels were analyzed at the point-of-care within minutes using only minute amounts of sample. The approach should be important for the diagnosis and management of numerous diseases and furthermore underlines how the synergy between synthetic chemistry and protein engineering can be exploited to create artificial biomolecules with highly unusual properties.
Kai Johnsson is Director at the Max Planck Institute for Medical Research, Department of Chemical Biology since 2017. He was appointed after being Full Professor at the Institute of Chemical Sciences and Engineering of the École Polytechnique Fédérale de Lausanne (EPFL). His current research interests focus on the development of chemical approaches to visualize and manipulate biochemical activities in living cells. His past achievements include the introduction of methods to specifically label proteins in living cells (i.e. SNAP-tag and CLIP-tag), the development of new fluorescent probes and sensors as well as studies on the mechanism of action of drugs and drug candidates.
Kai Johnsson is Associate Editor of ACS Chemical Biology since 2005. He is member of the Editorial Advisory Board of Science and of the Research Council of the Swiss National Science Foundation. He received the Prix APLE for the invention of the year 2003 of EPFL, the Novartis Lectureship Award 2012/13, the Karl-Heinz Beckurts Prize 2016 and is elected member of EMBO.

Title: Measuring the Expansion Rate of the Universe: Is ´Hubble´s constant´constant? (Presentation in English)
Date: Monday, 23 April 2018, 11:00 a.m.
Location: Carl-Bosch-Auditorium, Studio Villa Bosch, Schloss-Wolfsbrunnenweg 33, 69118 Heidelberg (Studio entrance between Villa Bosch and HITS)

Abstract:
Although systematic uncertainties may limit the accuracy of thermonuclear (Type Ia) supernovae as distance indicators for cosmology, they are at present the best tools to determine relative distances in the Universe. However, an extremely important question is: Can we determine accurate absolute distances also, reflected in the uncertainty of today’s expansion rate of the Universe, the Hubble constant H0. In fact, the present 5% discrepancy in H0 determinations between the cosmic microwave background and Type Ia supernovae either points at additional cosmological components or errors in the measurements, and this uncertainty on H0 is a severe limitation on an accurate determination of most other cosmological parameters. In this talk we will discuss several promising ways to obtain high-precision measurements of H0 in the near future.
Prof. Dr. Wolfgang Hillebrandt is retired director of the Max Planck Institute for Astrophysics (MPA) in Garching and Honorary Professor of Theoretical Physics at the Technical University of Munich since 1990. He obtained his doctoral degree from the University of Cologne in 1973, from where he moved to the Technical University in Darmstadt. In 1977 after his habilitation, he accepted an offer from the MPA and moved to Munich in 1978. In 1985 he became a Scientific Member of the MPA, and in 1997 a member of its Board of Directors. Honorary positions include the Chairmanship of the Astronomische Gesellschaft (1990-1993). His research is focused on various fields of theoretical astrophysics, such as nuclear and particle astrophysics, stellar structure and evolution, and, in particular, the final stages of stellar evolution. His research tools are mainly numerical simulations performed on supercomputers.
