How does the effectiveness of placebo tablets depend on their quantity, color and cost?

The effectiveness of a placebo depends on many characteristics of the dummy pills themselves. For example, taking two pills instead of one has a greater effect on the patient. Pills of different colors are suitable for different diseases: depression is best treated with yellow placebos, and stomach ulcers with white ones. The cost of pills is also essential - in many cases, more expensive ones give a greater effect than cheaper ones that are identical to them.

Random interesting fact from the Great Encyclopedia:

Why did Reason once send out an issue with a personalized cover to every subscriber?

In June 2004, every subscriber to Reason, a libertarian magazine with a circulation of 50, received a personalized edition. The cover featured the name and surname of the subscriber, as well as a satellite image with a note where his house was located. Thus, the magazine asked readers the question of the appropriateness of the government's broad authority to collect personal data.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Artificial electronic language prototype 24.11.2014

Scientists from the Kyiv National Shevchenko University (with a second affiliation at the Institute of Nanotechnology in the French city of Lyon) presented the concept of an artificial electronic language.

Scientists have come up with a sensor that analyzes substances and transmits information about them to a computer. According to its authors, the device will work in a similar way to a bunch of taste buds and the human brain.

The sensor is a three-layer two-dimensional structure. The base consists of silicon, on which a layer of liquid substance is deposited, which is subjected to analysis. Closes everything on top of the third layer - glass. Scientists used the fact that the conductive properties of such a system (transport of electrons under the action of light incident on glass) depend on the intermediate (second) liquid layer.

In their opinion, typical linguistic sensations are determined by the type of liquid, and the conductive properties of the system can be associated with it, which must be known in advance and used to determine the taste of the liquid.

Ukrainian scientists believe that their work can be used in the pharmaceutical and food industries, customs, environmental control services and other areas where an artificial analogue of human language may be required.
