    Pillar of the frost

    Two huge Helium tanks are chilling in BESSY´s garden for more than five years already, awaiting their job-to-do when the new bERLinPro energy recovery project starts to run. Today a third huge item burst the scene: An 18 meters Nitrogen tank arrived from Czech Republic, coming in here in the morning hours. The driver must have been a guy from hell: He precisely manoeuvred the tank backwards …

    Benjamin Palmer und Nir Funt bei Bessy: Von der Natur lernen

    Die beiden Chemiker Benjamin Palmer und Nir Funt vom israelischen Weizmann Institute of Science sind auf dem Gebiet der Biomineralisierung tätig und kamen als Nutzer an den Elektronenspeicherring BESSY II. Sie erforschen, wie Pflanzen und Tiere harte, mineralisierte Teile wie zum Beispiel Zähne, Knochen, oder Panzer herstellen und nutzen. Besonders interessiert sind die beiden daran, wie manche …

    Ana García Prieto: Mit Bakterien gegen den Krebs

    Oft sind es die kleinen Dinge, die helfen können, große Herausforderungen zu meistern. So auch im Falle von Ana García Prieto von der Universität des Baskenlandes. Sie kam im März 2017 nach Berlin und untersuchte an BESSY II das Bakterium Magnetospirillum gryphiswaldense – unter anderem in der Hoffnung, damit in Zukunft Krebs heilen zu können. Eine schwierige Aufgabe, bei der Ana García Prieto zum …

    Accelerator tourism Part 8: Swiss Light Source & Swiss FEL

    The last annual meeting of the „ESLS-RF“ (which stands for “European Synchrotron Light Source-Radio Frequency”) experts in November 2016 was hosted by the Paul Scherrer Institute, PSI, near Villigen. Softly settled in the middle of a smooth Switzerland landscape on both sides of the Aare river, it´s a huge center for research in the fields of matter, material, energy, health and …

    Follow me please: The Gun

    Currently the GunLab enthusiasts, scientists and engineers involved, are heavily busy @GunLab and again and again agreeing on working schedules there, since it´s too narrow there and not much space to move and work. They have to coordinate slots, and these slots allow each of them to work what and when.Entering it today, I again passed the entrance of the HoBiCaT bunker, as described in the …

    Accelerator tourism Part 7: SOLEIL, France

    Past October I visited the synchrotron SOLEIL, literally translated "Sun", southwest of Paris (France). SOLEIL is an acronym for "Source optimisée de lumière d’énergie intermédiaire du LURE", and I got the impression, the national french synchrotron close to Saint-Aubain is - oh là là, we are in France - quite a beauty in building, garden and entire facility including the (to my opinion) fancy …

And of course this information will be put into one of HZB´s much-coveted green …

    Moving magnets and a missing bunch of flowers

    Maybe it´s trivial, but to me it´s not. Watching a new accelerator "growing" is not only about science, money, regular meetings, having a building site with various companies and whatever else. It´s a story of a million details which have to be considered and lined like beads on a chain. Hence for me it´s always a little adventure and highly fascinating to sneak a round to Testing Halle or the …

    Awaiting Budker´s Eleven

    The HZB institutes for Accelerator Science and SRF Science & Technology (Superconducting Radio Frequency) hold a strong and for a long time already traditional cooperation with the Budker Institute of Nuclear Physics, BINP in Novosibisk (Russia).

    Protein structure: Reality check

    The computergame fold.it is a very successful citizen science project to inquire the complicated structures of proteins. But It can propose some protein structures, "in silico", which are not found in the real world. Summerstudent Rafal, who worked in the MX-team during summer, told me: "fold.it is fine, and I am sure that such simulations will become better in the future. But the reality check …

    Function follows form: how BESSY II helps with drug design

    Proteins or enzymes play a crucial role in many processes within the body. They can be huge molecules, sometimes several thousand atoms large. And they can have really complex shapes. We need to know every wrinkle or fold, since this is deciding how they interact with other molecules, for instance drugs. This is no trivial task: In a first step, we need to grow protein crystals, to arrange the …

    The Paper Mountain: how often is your paper cited?

    Read this (and weep): Nature and Thomson Reuters published a list of the 100 most cited papers since 1900. And had a look at citations of science papers overall: So 50 per cent of all papers are never cited at all or at most: only once. And breakthroughs in physics are missing among the Top 100: The discovery of high-temperature superconductors or the first observations that the expansion of the …
