For 205 days in 2011, Jens Titze, Professor of Electrolyte and Circulatory Research at the University of Erlangen-Nuremberg, and his team strictly controlled the diet for the Mars500 test subjects during their virtual flight to Mars. Sometimes the selected food contained a lot of salt, sometimes very little. The unexpected result of the longest sodium metabolism study to date was that the assumption that the human body would excrete the salt within 24 hours was incorrect. Instead, the human body stores salt for much longer before releasing it – an important discovery for medical research and patient care.]]>Tue, 08 Jan 2013 17:50:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.dlr.de/dlr/presse/en/desktopdefault.aspx/tabid-10172/213_read-5990/http://www.kit.edu/visit/pi_2013_12443.phpHelmholtz - Press Releases shown on Homepage

Dr. Andrei Varykhalov and his colleagues in the group of Prof. Dr. Oliver Rader investigated at BESSY II the electronic properties of nickel coated with graphene and achieved an astonishing result. They could show that the conduction electrons of the graphene behave rather as light than as particles. Physicists had originally expected such behavior only for freestanding graphene layers which show a perfect honeycomb structure and not for graphene on nickel which disturbs the perfect hexagonal symmetry. Their results are supported by calculations of two theoretical groups using novel concepts. Their report was published yesterday evening in the open access journal, Phys. Rev. X, the new top...]]>Fri, 21 Dec 2012 10:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.helmholtz-berlin.de/pubbin/news_seite?nid=13643;sprache=en;typoid=3228http://www.dkfz.de/en/presse/pressemitteilungen/2012/dkfz-pm-12-66-Preventive-Detention-for-Oxidizing-Agents.phpHelmholtz - Press Releases shown on Homepage
Oxidative stress is believed to cause a number of diseases. Up to now, it has been common practice to measure oxidative stress levels by determining the oxidation state of a small molecule called glutathione in cell extracts. Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have been the first to discover that cells under stress deposit their oxidized glutathione in a cellular waste repository. This protects cells from oxidative stress – and questions the validity of the conventional measuring method.]]>Mon, 17 Dec 2012 11:27:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.dkfz.de/en/presse/pressemitteilungen/2012/dkfz-pm-12-66-Preventive-Detention-for-Oxidizing-Agents.phphttp://www.desy.de/news/@@news-view?id=4221&lang=engHelmholtz - Press Releases shown on Homepage

Phagocytes ingest particles as well as pathogens from their surroundings into compartments called phagosomes. The phagosomes possess a harsh milieu with microbicidal function; therefore the phagocytes represent the first line of defense against infections. However, some intracellular pathogens, including members of mycobacterial species, manipulate the phagosomes to survive within them.]]>Tue, 11 Dec 2012 00:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.helmholtz-hzi.de/en/news_events/news/view/article/complete/new_insights_on_phagosome_maturation/http://www.dkfz.de/en/presse/pressemitteilungen/2012/dkfz-pm-12-65-Cocktail-Boosts-Immune-Cells-in-Fighting-Cancer.phpHelmholtz - Press Releases shown on Homepage
Natural killer cells (or NK cells), as part of the body´s immune system, can effectively fight cancer. Unfortunately, they quickly lose their aggressiveness and hence are unable to reject solid tumors. Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now discovered a cocktail consisting of three different immune mediators that leaves NK killer cells active over a long period of time. In mice, cocktail-boosted NK cells let tumors shrink. The cocktail was able to persistently activate human NK cells, too.]]>Thu, 06 Dec 2012 10:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.dkfz.de/en/presse/pressemitteilungen/2012/dkfz-pm-12-65-Cocktail-Boosts-Immune-Cells-in-Fighting-Cancer.phphttp://www.fz-juelich.de/SharedDocs/Pressemitteilungen/UK/EN/2012/12-012-03solliance.htmlHelmholtz - Press Releases shown on Homepage

With the X-ray vision of DESY's light source DORIS, a research team from Hamburg and Iceland has uncovered the molecular structure of a master regulator central to the most deadly form of skin cancer, melanoma. The results, published in the scientific journal "Genes & Development", throw new light on the workings of the so-called Microphthalmia-associated Transcription Factor MITF, that is not only connected to skin cancer, but also to a variety of hereditary diseases where the production of the skin pigment melanin is disturbed, and to certain aspects of ageing. "Our data could provide a rational basis for the development of tailor-made drugs targeting MITF", explains first author Vivian Pogenberg from the Hamburg branch of the European Molecular Biology Laboratory (EMBL).]]>Sat, 01 Dec 2012 00:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.desy.de/information__services/press/pressreleases/@@news-view?id=4201&lang=enghttp://www.helmholtz-hzi.de/en/news_events/news/view/article/complete/traffic_cops_of_the_immune_system/Helmholtz - Press Releases shown on Homepage
Molecule called IκBNS in charge of regulatory immune cell maturation. A certain type of immune cell – the regulatory T cell, or Treg for short – is in charge of putting on the brakes on the immune response. In a way, this cell type might be considered the immune system"s traffic cop. Now, scientists at the Helmholtz Centre for Infection Research (HZI) have looked into the origin of Tregs and uncovered a central role played by the protein IκBNS.]]>Thu, 29 Nov 2012 18:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.helmholtz-hzi.de/en/news_events/news/view/article/complete/traffic_cops_of_the_immune_system/http://www.dlr.de/dlr/presse/en/desktopdefault.aspx/tabid-10172/213_read-5773/Helmholtz - Press Releases shown on Homepage
To the naked eye there is nothing to see, and yet the small transparent container holds something never observed before. For the first time, scientists are studying asteroid dust collected by a spacecraft and returned to Earth. Ute Böttger, from the Institute of Planetary Research at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), belongs to one of 11 teams across the world that are carrying out scientific work on the asteroid particles from the Japanese Hayabusa mission.]]>Wed, 28 Nov 2012 14:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.dlr.de/dlr/presse/en/desktopdefault.aspx/tabid-10172/213_read-5773/http://www.hzg.de/cms01/public_relations/press_releases/034817/index_0034817.html.enHelmholtz - Press Releases shown on Homepage
A membrane consisting of polymer fibres and proteins makes a novel filter for tiny, nano-scaled particles in aqueous solutions. The result of such a research, which was done by Professor Mady Elbahri and his team from the Institute of Material Science at the Christian Albrecht University University in Kiel (CAU) and the Institue of Polymer Research at the Helmholtz-Zentrum Geestacht (HZG), has recently been published as the cover article in the current issue (21.11.2012) of "Advanced Functional Materials".]]>Tue, 27 Nov 2012 09:13:44 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.hzg.de/cms01/public_relations/press_releases/034817/index_0034817.html.enhttp://www.dzne.de/en/about-us/public-relations/meldungen/2012/press-release-no-26.htmlHelmholtz - Press Releases shown on HomepageMon, 26 Nov 2012 00:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.dzne.de/en/about-us/public-relations/meldungen/2012/press-release-no-26.htmlhttp://www.mdc-berlin.de/en/news/2012/20121122-new_risk_factor_identified_for_high_blood_/index.htmlHelmholtz - Press Releases shown on HomepageMon, 19 Nov 2012 01:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.mdc-berlin.de/en/news/2012/20121122-new_risk_factor_identified_for_high_blood_/index.htmlhttp://www.desy.de/information__services/press/pressreleases/@@news-view?id=4061&lang=engHelmholtz - Press Releases shown on Homepage
With their ultra short X-ray flashes, free-electron lasers offer the opportunity to film chemical reactions or atoms in motion. However, for this super slow motion the arrival time and the temporal profile of the pulses must be precisely known. An international team of scientists has now developed a measurement technique that provides complete temporal characterization of individual FEL (free-electron laser) pulses at DESY´s soft-X-ray free-electron laser FLASH. The team, led by Adrian Cavalieri from the Center for Free-Electron Laser Science (CFEL) in Hamburg, was able to measure the temporal profile of each X-ray pulse with femtosecond precision (a femtosecond is a quadrillionth of a second). Their technique can be implemented at any of the world´s X-ray free-electron lasers, ultimately allowing for most effective utilization of these sources. The results are published in the current issue of the scientific journal “Nature Photonics”.]]>Mon, 19 Nov 2012 00:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.desy.de/information__services/press/pressreleases/@@news-view?id=4061&lang=enghttp://www.helmholtz-hzi.de/en/news_events/news/view/article/complete/appetite_suppressant_for_scavenger_cells/Helmholtz - Press Releases shown on Homepage
When infected with influenza, the body becomes an easy target for bacteria. The flu virus alters the host’s immune system and compromises its capacity to effectively fight off bacterial infections. Now, a team of immunologists at the Helmholtz Centre for Infection Research (HZI) and cooperation partners has discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral genome – and then signals scavenger cells of the immune system to ingest fewer bacteria. The researchers published their findings in the Journal of Innate Immunity.]]>Thu, 15 Nov 2012 10:00:00 +0100feed_themeonline@helmholtz.de (Helmholtz-Gemeinschaft)http://www.helmholtz-hzi.de/en/news_events/news/view/article/complete/appetite_suppressant_for_scavenger_cells/
