Researchers discover gene that turns bees into social parasites
A small change in the genetic makeup of the South African Cape bee turns the socially organised animal into a fighting parasite. This change ensures that infertile worker bees begin to lay their own eggs and fight other colonies. In the current issue of the journal "Molecular Biology and Evolution", an international research team led by Martin Luther University outlines for the first time the genetic basis for this rare phenomenon.
Cardiovascular diseases and nutrition in Europe
Of the 4.3 million cardiovascular deaths in Europe in 2016, 2.1 million were the result of poor nutrition. Every second to third premature cardiovascular death could be prevented by better nutrition. These were the findings of an international research team led by the Martin Luther University, the Friedrich Schiller University Jena, the nutriCARD competence cluster and the University of Washington.
Increasing Impacts of land use on biodiversity
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.
The German Bundesliga: Are the players worth the money?
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.
New Max Planck Fellow Dirk Hanschel
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.
Mere sunlight can be used to eradicate pollutants in water
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.
Researchers present a unique database on Earth’s vegetation
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.
Bacteria: Protein researchers decipher resistance mechanism
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.
Psychologists study how couples handle laughter
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.
Physicists from Halle grow stable perovskite layers
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.
Root extract makes worms to live longer
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.
