This is shown in a dissertation by Niklas Elmqvist at Computer Science, Chalmers. He has also developed new methods for guided sightseeing in the 3D-world.
Three-dimensional computer environments have great potential for entertainment, education and simulation of activities that are either too difficult or too expensive to perform in the real world.
However, one problem with computer-based 3D environments is that it is easy to lose track of where you are and where you are going. In his dissertation, Niklas Elmqvist presents new methods designed to help the user effortlessly understand and move through this type of complex 3D environments.
This is achieved by taking advantage of the visual cues that we humans normally make use of to perceive our surroundings, such as size, shape, and motion.
Beyond X-ray vision and automatic sightseeing tours, he introduces a method where the user is equipped with a special force field for pushing away objects that get in the way.
Niklas Elmqvist also describes in the dissertation methods for graphically showing a course of events. These methods can be used to trace complex chains of cause and effect for such examples as large computer networks, like the Internet, biological processes, or advanced mathematical problems. The methods have so far been applied to visualization of scientific articles to help show how ideas and trends appear and develop.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

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...
