Fixing of the lumbar vertebral column aided by simple radiological techniques facilitates the process and avoids complications. This technique has arisen as a result of the conclusion of the PhD thesis by Dr. Matías Alfonso, specialist in the Department of Orthopaedic and Bone Surgery at the University Hospital of Navarre, and has been based on research carried out on a pedicular screw method based on intraoperatorial anatomical references. The study has been applied to 44 patients attending the University Hospital.
The insertion of pedicular screws into the lumbar vertebral column is suitable for the treatment of fractures, problems of instability due to degenerative illness, tumours, etc. It involves a routine technique in orthopaedics and bone surgery. Nevertheless, lesion of the nerve roots can occur as a complication, a risk that can affect up to 3% of patients.
The University Hospital has evaluated a method to guarantee the pedicular screw system in a reliable way, avoiding the neurological complications. This system groups together a series of radiological projections by means of which we can see to the borders of the vertebrae, thus enabling the path of the screws to be ascertained with precision.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
