In a previous project György Horvath used specially trained dogs to demonstrate that ovarian cancers emit a specific scent. The dogs were able to use this scent to distinguish between ovarian cancer tissue and both normal healthy abdominal tissue and other gynaecological cancers. The discovery that the blood of patients with ovarian cancer also has this same specific scent was published in the journal BMC Cancer.
Together with professor Thomas Lindblad from KTH and researcher Jose Chilo from Gävle University, Horvath has worked on detecting this scent using an existing electronic nose at KTH.
“We’ve managed to detect and register the scent from a form of ovarian cancer, and the scent from a healthy Fallopian tube and healthy womb muscle,” says Horvath. “This technical confirmation of a cancer scent will have major practical implications – a sufficiently sensitive and specific method could save hundreds of lives a year in Sweden alone.”
A more sensitive electronic scent detector that was recently tested. The basic structure is the same as with existing electronic noses, but they have added several new components to increase its sensitivity.
“Our goal is to be able to screen blood samples from apparently healthy women and so detect ovarian cancer at an early stage when it can still be cured,” says Horvath.OVARIAN CANCER

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
