Molecular scissors help evolutionary investigation

Scientists at KIT (Karlsruhe Institute of Technology) detected an important mechanism in the evolution of plant genomes: Using Arabidopsis thaliana as a model organism, they studied the formation of tandem repeat DNA sequences ...

Flower power—photovoltaic cells replicate rose petals

With a surface resembling that of plants, solar cells improve light-harvesting and thus generate more power. Scientists of KIT (Karlsruhe Institute of Technology) reproduced the epidermal cells of rose petals that have particularly ...

Solar power home storage systems put to test

Home storage systems for electricity produced by photovoltaics facilities are gaining attractiveness, as their costs are declining. However, standardized, verifiable criteria for the end client to assess their performance ...

How much noise is produced by wind turbines?

Wind energy is to have a major share in the future renewable energy mix. The Germany-wide TremAc project is aimed at improving the planning, development, and acceptance of wind power plants and at developing objective criteria ...

Mobile radio network measures rainfall

Raindrops attenuate propagation of electromagnetic waves. Using specially developed software, researchers can derive information on rainfall from radiation fluctuations along radio links of mobile radio networks. This technique ...

Risk aversion impedes innovation in information technology

Smartphones and tablets come from Asia and the USA, German and European industry is far behind. The causes are dealt with by a study of KIT published in the journal Telecommunications Policy. According to this study, risk ...

Unveiling the grammar of biological cells

Cells in the body exchange a number of signals with their surroundings. Deficient signal pathways may adversely affect the function of cells and cause diseases. However, we hardly know more than the vocabulary of cellular ...

Successful laboratory test of photoswitchable anti-tumor agent

Photoswitchable agents might reduce side effects of a chemotherapy. So far, photodynamic therapies have been dependent on oxygen in the tissue. But hardly any oxygen exists in malignant, rapidly growing tumors. A group of ...
