By means of a microelectrode that measures the impedance and temperature of the tissues, the system enables the state of any organ to be monitored from the moment of its extraction, during its transport, to the moment of the surgical operation to transplant it into a patient.
The Ikerlan-IK4 device, designed in collaboration with the National Centre for Microtechnology (CNM-CSIC) and the Carburos Metálicos company and patented in conjunction with I2M Design S.A., uses a polymer substrate that represents a great advance in biomedical instrumentation, as it does not produce injury in the tissues during transport or surgical manoeuvres. It even opens a new way to control organ rejection, given that the microelectrode can remain implanted for a considerable time without causing injury.
The application has a number of prototypes already and has had clinical trials with organs of animals at Barcelona’s Hospital Clínic. Moreover, it is of particular interest for a process as delicate as an organ transplant, as it provides an objective indicator of the evolution of the organ in which, despite the conservation techniques used – whether with special liquids or in cold -, the duration of the viscera is highly limited (12 hours in the case of the kidney, eight for the liver and only four hours in the case of the heart). The device is used incorporated into a small electronic system which gathers and sends data by telemetry to an external system, enabling the verification of the state of the organ at all times.
Due to medical advances, the transplant of organs is an evermore common medical practice. Thanks to the high number of donors in the Basque Country, this country has one of the highest rates of transplants in the world, with 61 kidney transplants per million inhabitants in 2006; 26.3 liver transplants and 4.7 heart transplants.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
