Pedagogues and psychologists involved in education are striving to make training more efficient. To achieve this, it would be useful to understand what happens in a trainee’s brain during learning. Only neurophysiologists can sort that out, however, not everything is clear to them yet.
Thus, it can be expected that memorizsation and reminiscence processes (which make the essence of training) should be reflected in changes of the brain’s electrical activity nature. It means that these changes may be recorded with the help of the most traditional brain investigation method - Electroencephalogram (EEG).
The research carried out by physiologists of the Institute of the Human Brain (Russian Academy of Sciences) in St. Petersburg and the Institute of Cognitive Neurology (Modern Academy of Humanities) in Moscow involved 57 persons under investigation – students of the Modern Academy of Humanities aged 17 to 20. They were to learn seven pairs of words – in Russian and in Latin which was previously unknown to them. Each pair of words was presented on the monitor screen for 5 seconds. The students were tested in a minute and a half – Russian words were shown to them and they had to recollect the Latin equivalent. Experimenters recorded students’ EEG through 19 electrodes laid on the head skin in three states: at rest, while memorising information and when extracting the information from memory.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
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...
