“4D ecography may well be a significant advance in the prenatal diagnosis of congenital cardiopathy”, explained Dr. Juan Luis Alcázar, specialist at the Obstetrics and Gynaecology Department of the University Hospital (University of Navarre).
One of the most recent novelties in ecographic studies has been the application of a fourth dimension, i.e. movement added to three-dimensional reconstruction. According to Dr. Alcázar, “the development of the STIC system, carrying out the spatio-temporal correlation of images, adds movement to 3D ecography. In this way, apart from obtaining exclusively anatomic information, structure from a functional perspective is evaluated”.
One of the great advances of this technique is its application to the foetal heart. Concretely, the STIC system enables a 3D reconstruction of the foetal heart in real time and with movement. This procedure changes the approach to prenatal diagnosis of congenital cardiopathy. It is one of the most common congenital anomalies of the foetus, although to date it has been difficult to detect in pregnancy. The foetal heart is a very small organ that moves very fast (120 beats a minute) and thus, its anatomical study is complicated.
The spectrum of foetal cardiopathies is very wide, from asymptomatic lesions to malformations incompatible with life, needing specialised training. In this sense, knowledge of a foetal cardiopathy can change procedures during childbirth, such as attending a reference centre that guarantees immediate specialised attention. STIC provides important information that can increase the accuracy of the prenatal diagnosis of these pathologies. Apart from facilitating the detection of more lesions, this system enables a refining of the diagnosis and provides guidelines for early treatment.
Another application for the 7system being studied involves foetal movements. The Department of Gynaecology is working in conjunction with that of Neuropediatrics to establish movement patterns for foetuses of between 24 and 34 weeks. When a child of this gestational age is born and their movements studied, normally parameters for children of 40 weeks are applied; nevertheless, their neurological maturity is not the same and, thus, there exist doubts as to whether the patterns used are the correct ones.
Four dimensions’ technology enables the study of the foetus while it is within the maternal uterus and the visualisation of the movements of the limbs, facial gestures, and so on. These data enables the establishment of patterns more adjusted to their intrauterine neurological development for their subsequent postnatal examination.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
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...
