Conditioning that once worked with Pavlov’s dog does also work with an artificially induced change in nerve cell activity.
The reason why male bees collect scents in pockets on their hind legs remained a mystery for a long time. As an attractant? As a wedding gift? To show off to other males? Researchers have now figured it out.
Carbon nanotubes not only shine brighter in the presence of dopamine, but also for longer. The time period of shining serves as a new parameter to detect biological messenger substances.
Chemotherapy treatments produce strong side effects. A new agent that accumulates in the tumour tissue and is activated there by ultrasound waves does not have this problem.
Feeling like we have a degree of control makes us tolerate pain better. In the case of fibromyalgia, however, this simply doesn’t work. A study provides clues as to why.
Genes influence different structures and the function of the brain. These in turn explain differences in behaviour. Analysing all three aspects at once is a challenge – but has now been achieved.
Using a new technique, researchers were able to observe live what happens in the first picosecond when a proton detaches from a dye after exposure to light.
International researchers propose an operational methodology for mapping and assessing ecosystem services process to inform the policy in Eritrea and beyond.
Funded by the European Research Council with 2.5 million euros, Gregor Leander is developing new encryption methods. He wanders off the beaten track and doesn’t simply rely on the principle of trial and error.
We are growing more and more dependent on digital navigation. Frank Dickmann is researching ways of improving our individual spatial orientation skills in spite of this trend.
Even though mathematically verifiable secure encryption algorithms do exist, in practice attackers manage to hijack data on a regular basis. This is because encryption doesn’t happen merely in theory.
Researchers recommend better integration of argumentation skills in teacher training.
Attackers have the ability not only to manipulate software, but also to tamper with the hardware. A team from Bochum is devising methods to detect such tampering.
The potential for energy and material savings offered by additive manufacturing compared to conventional processes is enormous. But the devil is in the details.
A combination of photochemistry and mechanochemistry saves 98 per cent solvent and 80 per cent energy in a number of reactions. What’s more, the process takes less time than it does in solution.
It makes a big difference whether someone perceives a test as a challenge or a threat. Examiners can have an influence on this.
Researchers have clarified the molecular structure of an enzyme class, enabling them to use bacteria to produce prodrugs.
Drones shouldn’t be able to fly over airports and should have a unique serial number. In theory.
Animal consciousness should not be thought of as a light switch, which can be on or off, Bochum philosophers say. They advocate a different approach.
A new experiment has made it possible to observe the effects of an electron in solution on the surrounding liquid.
