Virtual reality that allows doctors to visualise the heart in three dimensions could help in the diagnosis of heart conditions. A pilot study published today in the open access journal Cardiovascular Ultrasound reveals that doctors can diagnose heart conditions quickly and easily from virtual three-dimensional animated images or ’holograms’ of the heart. Three-dimensional (3D) holograms allow doctors to ’dive’ into the beating heart and see interior parts of the organ.
Annemien van den Bosch and colleagues, from Erasmus MC University Medical Center Rotterdam in The Netherlands, projected ultrasound-generated 3D images of hearts (echocardiograms) in a specially designed four-walled room called the I-Space. In the I-Space, images are projected on three of the walls and the floor, which results in an animated hologram floating in space in front of the viewers. The viewers wear a pair of glasses with polarising lenses allowing them to see the hologram with depth.
Van den Bosch et al. asked ten heart specialists to analyse the holograms of patients with a heart defect that affects the shape of an inside part the heart, and of patients with a healthy heart. The doctors learnt how to use the equipment and were able to virtually ’cut through’ the heart to see inside, using a virtual pointer, within ten minutes. The ten doctors could all distinguish healthy from unhealthy hearts and make the correct diagnosis within only ten minutes.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
