For this, it is essential to provide tests that allow early detection of cancer without the need of a tissue sample, and thus drastically improve the prognosis of the patients and their chance of a cure. Currently established cancer diagnostics either identify the disease too late or are unreliable, resulting in false positives, which can unsettle patients.
For instance, measuring PSA-levels for prostate cancer detection and mammographies for breast cancer prevention can provide false positive results without acute malignancies being found. Additionally, currently no blood test is available for oral cancer.
A novel blood test for the detection of cancer has been clinically assessed in a collaborative study between the university hospital Tuebingen, the German Cancer Research Center in Heidelberg, and the Clemenshospital of the university hospital muenster. This blood test utilizes the immune system; specifically the activity of macrophages, a type of white blood cell that scavenges tumor cells.
Using laser-based detection methods of tumor material within these scavenger cells, also known as EDIM (epitope detection in monocytes)-technology, it is now possible to discover the presence of tumor cells in small blood samples. This has allowed the early detection of oral, prostate, and breast cancer as well as relapses in patients by the EDIM-technology. Thus, this technology is also suitable for monitoring therapeutic efficacy. The results of this study represent an important hallmark in cancer detection, driven by the improved accuracy of the EDIM-blood test compared to previously established test methodologies.

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.
Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.
In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.
Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
