Serine substitution in Amyloid-β – a possible link between β-Methylamino-L-alanine and Alzheimer’s disease?
In 1944 Guam was recaptured and fortified by US forces. Decades later soldiers that were stationed at Guam developed ALS-PDC (amyotrophic lateral sclerosis–parkinsonism/dementia complex) 50-100 times the incidence of ALS. Also Guam’s natives, the Chamorro, are plagued by severe neurodegenerative diseases. When looking for a possible cause for this phenomenon, scientists soon focused on the neurotoxin BMAA, found in cycad tree fruits, an important food source in Guam. BMAA is a non- proteinogenic amino acid produced by cyanobacteria that can be enriched via the food chain in plants, seafood and higher animals. This is a critical factor because cyanobacteria are known for their excessive blooms not only in marine ecosystems but also in lakes that are used as fresh water source for millions of people.

The number of scientific publications and journals is increasing constantly. Researchers have to stay current with ever more new scientific literature in their field and are also under increasing pressure to visibly publish their own findings in competition with their colleagues in the field. At the same time, it is become increasing difficult, particularly for non-scientists, to identify which journals are serious scientific publications. The large number of new online journals also includes “pseudo-journals” where the selection, editing and review of the submitted articles is often not transparent or does not meet scientific standards.France’s Académie des sciences, the German National Academy of Sciences Leopoldina, and the UK’s Royal Society are drawing attention to this situation and have developed joint guidelines for high-quality publications in scientific journals. These were presented to the EU Commissioner for Science and Innovation, Carolos Moedas, in Brussels.

New, time limited and complex – such are the tasks generally undertaken as projects. A work environment without project work is almost unimaginable nowadays. And this is not only true for the non-academic sector: Even the doctorate is a project!
Proven project management tools pave the way for the professional development and planning of projects, for competent guiding of their implementation and for their successful completion. With the help of these tools even difficult steps in the project journey can be safely navigated.

Polymers on Surfaces – or how to catch them all
The talk will feature recent developments in the lab. It focuses mainly on the preparation of thinnest polymer films / single molecules under UHV condition. It introduces the techniques quadrupole mass spectrometry (QMS), quartz microbalance (QMB) and scanning tunneling microscopy (STM) and how their results should lead to a successful preparation. A short overview of what is coming next will be given at the end of the talk.
Location: MLU Halle-Wittenberg, Von-Danckelmann-Platz 3, SR 1.03, 06120 Halle (Saale)
