Problems and perspectives concerning the existence of large-scale magnetic fields are described. Heeding observations, possible origins and implications of magnetic fields in spiral galaxies and in regular clusters are scrutinized in different cosmological frameworks including scenarios where conformal invariance is broken because of the evolution of the gauge couplings. The generation of the B...

Colonoscopy is usually perceived as an invasive and potentially painful procedure, being also affected by a small, but definite, risk of major complications (cardiopulmonary complications, perforation, hemorrhage) and even mortality. To improve both acceptability and safety, PillCam Colon Capsule Endoscopy (CCE) (Given Imaging Ltd, Yoqneam, Israel) has been developed. CCE represents a non-invas...

All humans experience itch in the course of their life. Even a discussion on the topic of itch or seeing people scratch can evoke the desire to scratch. These events are coined "contagious itch" and are very common. We and others have shown that videos showing people scratching and pictures of affected skin or insects can induce itch in healthy persons and chronic itch patients. In our studies,...

The suggestion to tax people on earnings capacity instead of earnings has been around for a long time and is attractive in terms of economic efficiency. In this paper we reflect on the feasibility of such a system and give an exploratory empirical implementation. We apply the Leyden Welfare Function of Income, a survey based measure of an individual’s welfare associated with income, to derive i...

Cancer research has undergone radical changes over the last few years. The issue today is no longer the amount of molecular, cellular, and clinical information available, but how to handle it. Systems biology is the latest in a series of innovative strategies driven by technological advances that have provided us with a suite of “omics” (1). Technology advancements have enabled comprehensive ch...
