In advertising and electoral campaigns, it is normal practice: get people in the right mood, either by stimulating their feeling of happiness or by making them anxious, and the commercial or political project is more likely to be successful. In an educational setting, it is not usual to show, for example, a sad film in order to ‘sharpen the mind’. Nevertheless, it is possible to influence pupils with affective videos and, in so doing, achieve educational benefits.
Against a background of the shift from words to images and also to the emotion culture, Ria Verleur has researched ways of applying affective videos in Web-based learning environments. To see how the emotional responses to a video affect our ability to perform a task, she carried out some experiments with students. The presentation variables were: video display (type of media, screen size), video content (has positive or negative effect) and video design (audiovisual design variables).
An insight task showed that watching an unpleasant clip improved performance while a pleasant clip worsened it. However, when experimental subjects were given a divergent-thinking task, their scores were independent of whether or not a certain video clip had put them into a creative mood or mindset. In yet another experiment, students had to evaluate conflict situations in video clips. The design of the video – such things as the frame size (close-ups, long shots) or camera angle – influenced whether the subjects thought the main character in the video clip showed more emotion or less. The video design also affected their evaluation of the second character in the clips, even when the frame size was kept the same for this character.
The educational sector usually follows media trends – just as in daily life – so video screens will become larger (DigiBoard) but also much smaller as in iPod applications, mobile phones and mini TVs. Although these smaller screens appeared to be able to produce affective responses, Verleur’s findings suggest that large screens have more effect than smaller ones.
If affective as well as cognitive elements influence the learning process, then an ethical question arises regarding the means which may be employed to achieve certain educational goals. Ria Verleur does not provide an answer to such important questions in this exploratory investigation, but it is obvious that a relationship between affective processes and learning outcomes does exist. The question now, according to this educational expert at the University of Twente, is how do we recognize and exploit it?

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...
