Rapid population and economic growth are destroying biological diversity - especially in the tropics. This was reported by a research team led by the German Centre for Integrative Biodiversity Research and the Martin Luther University in Nature Ecology & Evolution. A constantly growing demand for agricultural products requires ever new cultivated areas. Even though technological advances are making agriculture ever more efficient, the growing number of people makes up for these successes.

Does the talent of footballers dictate their market value? Economists from Martin Luther University investigated this question in a new study. They calculated the relationship between the performance and market value of 493 players in the 1st and 2nd divisions of the German Bundesliga for the 2015/16 season. The study revealed that star players tend to be overvalued, while other players tend to be traded at below market value.

Dirk Hanschel, Professor of German, European, and International Public Law at Martin Luther University, will carry out a research programme on "Environmental Rights in Cultural Context" as a Max Planck Fellow at the Max Planck Institute for Social Anthropology in Halle starting in January 2019. The fellowship position, which is awarded by the Max Planck Society, is connected with a research grant of up to 500,000 euros.

Advances in environmental technology: You don`t need complex filters and laser systems to destroy persistent pollutants in water. Chemists at Martin Luther University have developed a new process that works using mere sunlight. The process is so simple that it can even be conducted outdoors under the most basic conditions.

Which plant species grow where, alongside which others? The diversity of global vegetation can be described based on only a few traits from each species. This has been revealed by a research team led by Martin Luther University and the German Centre for Integrative Biodiversity Research. In a new study published in the scientific journal "Nature Ecology & Evolution", they present the world`s first global vegetation database which contains over 1.1 million complete lists of plant species sampled across all Earth`s ecosystems.

Worldwide, resistance to antibiotics is on the rise. In order to understand why bacteria are becoming immune to previously well-functioning drugs, scientists are penetrating ever deeper into the molecular structure of cells. A research group at Martin Luther University has now succeeded in isolating a membrane protein from the E. coli bacterium and shed light on its molecular structure. Armed with this information, they have been able to show how the bacterium manages to rid itself of the antibiotic by forcing out the drug.

Laughter plays an important role in romantic relationships – whether or not it`s shared together or directed at the significant other. If partners handle laughter or being laughed at in a similar way, they tend to be quite content with their relationship. People who are afraid of being laughed at, on the other hand, are often less happy in their relationship. This also affects their partner and their sexuality, psychologists from Martin Luther University concluded in a study.

Crystalline perovskite cells are the key to cutting-edge thin-film solar cells. Although they already achieve high levels of efficiency in the laboratory, commercial applications are hampered by the fact that the material is still too unstable. Furthermore, there is no reliable industrial production process for perovskites. In a new study physicists at Martin Luther University present an approach that could solve this problem. They also describe in detail how perovskites form and decay. The results could help produce high-performance solar cells in the future.

A root extract of the Fallopia multiflora, or Chinese knotweed, has special properties: it enables the nematode C. elegans to live longer and protects it from oxidative stress. This has been demonstrated in a new study by nutritional scientists at Martin Luther University. The researchers provide scientifically substantiated evidence for the effectiveness of this extract, which is primarily used in traditional Chinese medicine and as a dietary supplement.

Forscher präsentieren einmalige Datenbank zur Vegetation der Erde
Welche Pflanzenart wächst wo und mit welcher anderen zusammen? Ein Forscherteam unter Leitung der Universität Halle und des Deutschen Zentrums für integrative Biodiversitätsforschung präsentieren in einer neuen Studie die weltweit erste, globale Vegetationsdatenbank mit über 1,1 Millionen kompletten Pflanzenartenlisten für alle Ökosysteme auf dem Festland.
Species-rich forests store more carbon
Species-rich subtropical forests can take up, on average, twice as much carbon as monocultures. This has been reported by an international research team in the professional journal Science. The study was carried out as part of a unique field experiment conducted under the direction of Martin Luther University, the German Centre for Integrative Biodiversity Research and the Chinese Academy of Sciences. The experiment comprises forests grown specifically for this purpose in China.

Many people do not get enough vitamin D. Brittle bones and an increased risk of respiratory diseases can be the result of a vitamin D deficiency. A research group at Martin Luther University and the Max Rubner-Institut has now identified a new, previously unknown source of vitamin D2: cocoa and foods containing cocoa have significant amounts of this important nutrient. According to the researchers, cocoa butter and dark chocolate have the highest amount of vitamin D2. They recently published their results in the journal "Food Chemistry".
