Increased numbers of electric and hybrid cars and reduction of feeding power from solar power plants into the net lead to a rising demand for new battery-systems. However, traditional energy conversion systems and energy saving systems are made of static series and parallel circuits comprising up to thousands of subunits to reach the wanted output voltage and amount of electricity (e.g. the Tesla S model has 6.000 battery cells). The major draw back here is that the cells all differ regarding aging and capacity and due to the underlying physical principle the weakest battery cell determines the electrical charge and the electrical efficiency. A new intelligent battery System from the Universität der Bundeswehr Munich can overcome this disadvantage.
The incidents of 9/11 have led to a tremendous reinforcement of the security checks at airports in the last years. However, increasing number of passengers, new materials for explosive agents and the high variety of weapons are challenging existing safety engineering methods. To date, no perfect solution exists that does prevent the smuggling of unwanted gadgets on board. Scientists of the Ludwig-Maximilians-University from Munich have invented a new method that provides a solution to this problem.

MODAG GmbH is the winner of the PEP Award 2014 in the category „Early stage start-up projects“. The PEP Promotor-program of the Federal Ministry of Education and Research is awarding the innovative start-up team for the development of a drug candidate for the treatment of neurodegenerative diseases.
While observing kitesurfers in practicing their sport one can hardly fail to notice how awkward it is to start or land a kite. This applies particularly to where space is limited. Thus, the laying out, tying up or winding up of the lines always bears the risk of tangling them up. Moreover, launching and landing of a 30m long kite system is hazardous for bystanders, if the kite is getting out of control.
In order to accommodate various wind conditions and skill level of the athlete kites in different sizes and line sets with different lengths need to be attached. Both options require that several kites and line sets need to be purchased and brought along beforehand. Re-attaching of the kite to a new line set can only be done on the shore and therefore requires landing of the kite and returning to the shore.
A newly developed kite system from the Technische Universität München allows for a variation of the line length while surfing on the water.

Chronic hepatitis C virus infections are among the most common reasons for liver transplants. Because existing viruses also infect the new liver, the immune system is highly active there. Despite this, the new organ is not rejected, as scientists from the Helmholtz Zentrum München and the Technische Universität München (TUM) have now discovered. The long-term stimulation of the innate immune system by the virus actually increases the probability of tolerance.

When can we expect to drive the length of Germany in an electric car without having to top up the battery? Chemists at the NIM Cluster at Ludwig-Maximilians-Universität München (LMU) and at the University of Waterloo in Ontario, Canada, have now synthesized a new material that could show the way forward to state-of-the-art lithium-sulfur batteries.
On behalf of the Technical University of Munich (TUM), the Bayerische Patentallianz GmbH is awarding a license to NavVis GmbH for an award-winning technology for navigating inside buildings. This technology, which was initially developed at TUM under the name of NavVis, allows navigation inside large buildings without the need of GPS. In addition, with the help of a mobile app for smartphone users this technology also opens up new possibilities for interactive services such as museum tours or product advertising in shopping malls.

Early nutrition is recognized as a target for the effective prevention of childhood obesity. Protein intake was commonly associated with more rapid weight gain during infancy, a known risk factor for later obesity. Now researchers from the Ludwig-Maximilians-Universität München (LMU) studied the influence of protein content in infant nutrition on the BMI of children years later and suggest foods that provide excessive protein intake should be avoided.

Photosynthesis takes place in specialized membrane systems, made up of stacked disks linked together by unstacked planar leaflets. An LMU (Ludwig-Maximilians-Universität) team has now identified a protein that tucks the membrane in at the edge of each stack. In the longer term, the new findings could contribute to the optimization of photosynthesis: Understanding the stacking process might allow one to increase the degree of stacking and enhance the efficiency of photosynthesis – and perhaps increase yields from crop plants.
