Their work, published in Current Biology, reports the discovery of iron balls in sensory neurons. These cells, called hair cells, are found in the ear and are responsible for detecting sound and gravity. Remarkably, each cell has just one iron ball, and it is in the same place in every cell.
A image showing cells from the inner ear of pigeons stained with a chemical that turns iron bright blue in colour. It highlights the balls of iron discovered by the Keays lab. Each ball of iron lies directly beneath the hairs, and there is just one per a cell. IMP
“It’s very exciting. We find these iron balls in every bird, whether it’s a pigeon or an ostrich” adds Mattias Lauwers who discovered them “but not in humans”. It is an astonishing finding, despite decades of research these conspicuous balls of iron had not been discovered.This finding builds on previous work by the lab of David Keays who last year showed that iron-rich cells in the beak of pigeons that were believed to be the magnetic sensors, were really just blood cells. “These cells are much better candidates, because they’re definitely neurons. But we’re a long way off to understanding how magnetic sensing works – we still don’t know what these mysterious iron balls are doing.” said Dr Keays. “Who knows, perhaps they are the elusive magnetoreceptors” muses Dr Keays “only time will tell”.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
