Copper is an essential element of our society with main uses in the field of electricity and electronics. About 70% of the copper comes from deposits formed…
The mineral erionite is considered to be highly carcinogenic and is on the World Health Organisation’s list of substances that cause cancer. A few years ago,…
Regardless of whether we are sitting in a loud aeroplane or walking through a quiet forest clearing, how humans perceive their environment depends on the…
Cases of newborn “shaking piglets” have been reported since the 1920s both in Europe and abroad. Yet an additional cause for these congenital tremors has so…
Solar cells made with films mimicking the structure of the mineral perovskite are the focus of worldwide research. But only now have researchers at Case…
This possibility is raised by a fundamentally new method for controlling a powerful but finicky process called the polymerase chain reaction. PCR was developed…

RadioNet will provide support for various aspects of radio astronomical research in Europe; it will enable scientists from all over the world to use the radio…
Bacterial cells have an added layer of protection, called the cell wall, that animal cells don't. Assembling this tough armor entails multiple steps, some of…
A team of scientists led by Ronald Harty, a professor of pathobiology and microbiology at the University of Pennsylvania's School of Veterinary Medicine, has…
Mechanical elasticity is a central parameter of living cells and tissues. Cancerous and healthy tissues, for example, have a different elasticity. Therefore, tools are under development to make tissue elasticity a new diagnostic marker in medicine1. Nevertheless, these efforts have been hampered by poor spatial resolution (i.e. ultrasound elastography) or by their usability being restricted to an in vitro environment (i.e. scanning ion conductance microscopy2,3,4 (SICM)).
Here, we present a novel instrument which transfers principles of SICM into the macro-environment of endoscopy or laparoscopy. This opens the door for a real-time measurement of tissue elasticity, e. g., during minimally invasive surgery.
Our handheld device uses the pressure of a water jet for inducing a deformation of the outer surface of any given tissue. The resulting change in a simultaneously recorded ion current between two electrodes on the “water nozzle” renders charac-teristic parameters for the elasticity of the tissue.
Device and method of treating objects & bulk materials with a physical plasma cushion at atmospheric pressure. The plasma passes from the discharge chamber to the treatment chamber through a sparger plate comprising a multitude of holes, producing a plasma cushion, which supports & slides/pushes the objects while treating them.
