Focus Description:

You have two dice in your hand. Throw them on the table. The bottom faces of the cubes are not visible to you. Take the cubes and show these faces to the viewer. Let him add up the glasses you cannot see. Put the cubes aside and correctly name the required sum of the two lower faces.

Focus secret:

You need to know that on dice, the sum of the opposite sides is always seven. If there are 2 points on one side, then there will be 5 on the other. You can see the top side of the cubes.

Let's say there are 4 and 1 on your side, that is, in total - 5. And the total sum of the two opposite sides on both dice is 14. So, to name the amount known to the viewer, subtract 14 from 5. Name it - 9. After all, on the faces the dice that the spectator saw were 3 and 6 points.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

Bees have emotions and mood swings 15.10.2016

Bees may experience something like happiness after receiving a treat that makes them feel more optimistic.

We usually think of emotions as internal awareness of a feeling, but there's a lot more to this subject, says Clint Perry of Queen Mary University in London. Physical changes and shifts in behavior accompany feelings of happiness and sadness.

To see if bees had similar patterns, Perry and colleagues trained 24 bees to associate certain locations and colors in the lab with cylinders of sugar or plain water. The scientists then closed the cylinders and gave half of the bees high-sugar water - the bee equivalent of chocolate - and measured the time it took for the insects to climb into the container with the hole. It was located between two closed cylinders and was painted in a medium color so that the bees would not know if there was sugar water in it or not.

The bees that received the sugar dose were quicker to get into the obscure medium feeder, as if they were more optimistic about the possibility that there was food there. And they didn't just act more actively because of the surge of energy. Both the bees that received a dose of sugar and the rest, with equal activity, climbed into the container, where there was definitely food, and with the same reluctance into the cylinder with plain water.

To see if a sugar cube could remove a negative experience, the researchers simulated a predator attack by carefully placing 35 insects in a trap that looked like a web of crab spiders. These spiders often prey on bees, but they can escape from them. Then the insects were released from the trap.

The bees given sugar flew to the feeder four times faster than those given nothing. It can be assumed that sweet food enhances positive emotions and helps to recover from negative ones - just like in humans.

After the bees were given a drug that blocks dopamine, which is responsible for the reward system in humans, all the effects of sugar virtually disappeared. This suggests that the bees behave according to their mood, Perry says.
