“Biological diversity is a widely under-appreciated resource that is essential for human existence and has a crucial role to play in sustainable development and in the eradication of poverty. Biodiversity provides millions of people with livelihoods, helps to ensure food security, and is a rich source of both traditional medicines and modern pharmaceuticals.” That is how UN Secretary-General Kofi Annan defined biodiversity at the International Day for Biological Diversity in 2003.
Humans intimately depend on biological capital, and without it, it would have been impossible to reach the level of prosperity that we currently enjoy. Plants have graced us with food, medicine,wood, and energy, but during the last century, human pressures and rapid industrial development have severely affected the natural heritage. The extinction of new species brings the irreversible loss of unique plants directly related to human development and prosperity.
Each plant has a genetic warehouse and biochemical information; the extinction of just one species can cause the loss of very important information for the human’s well-being. In addition biodiversity as the variety of all forms of life on earth is required for the recycling of essential elements such as oxygen, to reduce pollution and acts as a buffer against variations in weather and climate.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
