Kidney disease may affect as many as one in twelve people, and causes millions of deaths each year. Currently, the diagnosis of kidney function relies mainly on blood and urine tests, an indirect means of figuring out how well theyre working.
Standard MRI scanners, used to view many organs of the body, do not always show the whole picture for kidneys. This is because the MRI equipment found in hospitals and clinics works by imaging water molecules in the body. But in water-logged kidneys, the image may not distinguish between different functional parts. Now, Prof. Hadassa Degani of the Biological Regulation Department and her lab team have found a way to see into the kidneys using magnetic resonance imaging (MRI) that scans sodium ions rather than water.
Their method takes advantage of a unique feature of kidney function. Kidneys filter the blood and maintain steady levels of materials such as sodium and potassium in the bloodstream. To sustain control, these organs employ a gradient – a rising concentration of sodium from the outer layer, called the cortex, (where concentrations are around those of normal body tissues), towards the center, where levels reach up to five times the norm.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

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...
