The transit of the exoplanet 55 Cancri e is the shallowest detected from the ground yet, and the success bodes well for characterizing the many small planets…

MRIs are used predominantly in lung diagnostics. The innovation can be used as contrast agent. 3He is harmless when used as contrast agent and is already used in research for this purpose. Though modern MRIs can generate images from all body areas without any contrast agent, the use of 3He, in particular in examinations of the lungs, significantly increases the contrast and therefore the resolution, enabling cancer tumors or infections to be detected more efficiently.
Furthermore, the 3He magnetometer can be used in all forms of therapy that work using magnetic fields, such as thermotherapy with magnetic nanoparticles (nano-cancer therapy) that selectively impair tumor cells through heat. The magnetic fields used have to be adjusted individually before each therapy session.

In the analysis of biological samples, specimens are often investigated with methods in sequential order. In order to make this possible, the adequate preservation of samples is an essential prerequisite. A commonly used procedure is in this case the cooling of samples to -20° C to -80° C by freezing.
Disadvantageous is however so far that, due to insufficient thermal insulation sample temperatures gradually approximate the ambient temperature within the respective device. The sample to be investigated consequently thaws, which negatively influences the quality of downstream investigation procedures or even causes a destruction of the structural integrity of the specimen.
The invention solves this problem by the use of a hollow cylinder which consists of thermally insulating, X-ray translucent material as insulating body.

For the medical treatment of lung diseases pharmaceuticals are often applied by inhalation. The release of the active agent occurs within a very short time-period. If the release of the active agent is to be delayed in order to achieve a most uniform release during a longer period of time, aqueous dispersions of encapsulated active substances are used.
The basic idea of the innovation is the application of polymer solutions containing active substances and forming particles only after nebulisation at the intended site of deposition.

The ozone-based innovation allows to arrest progression of the tumor and to induce tumor regression up to a complete remission. The innovation comprises the utilization of a novel device for the application of an ozone- or ozonized oxygen-containing fluid in a human or animal torso or, more precisely, for intraperitoneal application, whereby application does not need to take place in immediate contact with the tumor in order to be effective.

Treatment with high energy radiation is a generally recognized method in cancer therapy. Instead of high energy radiation, particle therapy uses accelerated charged particles, such as protons or heavy ions (e.g. carbon). The difference between particle therapies in comparison to conventional radiotherapy is the deviant penetration behavior of the particles.The novel system provides the unique possibility of combined diagnosis and therapy by means of ion beams.
