    Description: Here we present the first high-resolution late-Holocene glacier record from the Lofoten archipelago in northern Norway. The study is based on analyses of lacustrine sediments from the distal glacier-fed lake Kveitvikvatnet (30.1 m a.s.l.), as well as glacial-geomorphological mapping of the ~4.2-km 2 surrounding catchment. The lake sediment cores have been examined for input of glacial-derived sediments by using physical, geochemical and magnetic sediment properties, including x-ray fluorescence (XRF), magnetic susceptibility (MS), grain size analyses, dry bulk density (DBD) and loss-on-ignition (LOI). Former glacier extent has been reconstructed using aerial photography and glacial-geomorphological mapping. Lichenometric dating has been used to construct a moraine chronology covering the recent fluctuations of the largest glacier (back to AD ~1740). AMS radiocarbon dating reveals that the lake sediment record covers the last 1200 years, thereby including both the ‘Little Ice Age’ (LIA) and the ‘Medieval Climate Anomaly’ (MCA). By linking continuously deposited lake sediment proxies of glacier fluctuation to known glacier frontal positions and an independent temperature reconstruction, former fluctuations in the equilibrium-line altitude (ELA) and winter precipitation have been reconstructed. Reconstructed winter precipitation estimates have also been correlated to instrumental data from the region back to AD 1895 and show a remarkable correlation, which further strengthens our approach. We found that both MCA and LIA were periods of substantial glacier variations with respect to the present, with a maximum lowering of the ELA of ~75 and ~85 m, respectively. Increased precipitation during these intervals, associated with more frequent and/or intense winter storms, is suggested to be the major driving force of glacier fluctuations in Lofoten.

    Description: The US National Institute of Neurological Disorders and Stroke convened major stakeholders in June 2012 to discuss how to improve the methodological reporting of animal studies in grant applications and publications. The main workshop recommendation is that at a minimum studies should report on sample-size estimation, whether and how animals were randomized, whether investigators were blind to the treatment, and the handling of data. We recognize that achieving a meaningful improvement in the quality of reporting will require a concerted effort by investigators, reviewers, funding agencies and journal editors. Requiring better reporting of animal studies will raise awareness of the importance of rigorous study design to accelerate scientific progress.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511845/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511845/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Landis, Story C -- Amara, Susan G -- Asadullah, Khusru -- Austin, Chris P -- Blumenstein, Robi -- Bradley, Eileen W -- Crystal, Ronald G -- Darnell, Robert B -- Ferrante, Robert J -- Fillit, Howard -- Finkelstein, Robert -- Fisher, Marc -- Gendelman, Howard E -- Golub, Robert M -- Goudreau, John L -- Gross, Robert A -- Gubitz, Amelie K -- Hesterlee, Sharon E -- Howells, David W -- Huguenard, John -- Kelner, Katrina -- Koroshetz, Walter -- Krainc, Dimitri -- Lazic, Stanley E -- Levine, Michael S -- Macleod, Malcolm R -- McCall, John M -- Moxley, Richard T 3rd -- Narasimhan, Kalyani -- Noble, Linda J -- Perrin, Steve -- Porter, John D -- Steward, Oswald -- Unger, Ellis -- Utz, Ursula -- Silberberg, Shai D -- P01 NS012151/NS/NINDS NIH HHS/ -- P30 MH062261/MH/NIMH NIH HHS/ -- R01 NS006477/NS/NINDS NIH HHS/ -- R01 NS034774/NS/NINDS NIH HHS/ -- R01 NS041574/NS/NINDS NIH HHS/ -- T32 MH020016/MH/NIMH NIH HHS/ -- T32 NS007280/NS/NINDS NIH HHS/ -- UL1 RR024160/RR/NCRR NIH HHS/ -- Z99 NS999999/Intramural NIH HHS/ -- England -- Nature. 2012 Oct 11;490(7419):187-91. doi: 10.1038/nature11556.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Neurological Disorders and Stroke, NIH, Bethesda, Maryland 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23060188" target="_blank"〉PubMed〈/a〉
