All kinds of plants and animals diverse at the bottom
A variety of vehicles were used in this study. The movement of those vehicles sent deep in the sea is controlled with the help of remote control.
These can be called robotic submarines. These vehicles can walk on the bottom of the sea. They have arms and legs with which they can collect different types of specimens. Then they are brought to the laboratory.
At many places to go deep in the Atlantic Ocean, the Atlas project, the scientists are sending. Send robotic submarines and C-gliders and collect various samples from there.
In addition, all the rare information will be collected from the depths of the sea with the help of GPS technology installed in these devices.

Exactly four hours after learning something, if physical exercise is done, then what I have learned can be remembered very well.
Dutch scientists are talking about this technique of remembering something. They conducted research on the memory of 72 people.
Protein is excreted from the body during exercise.
Exercise should be done after exactly four hours
Exercise should be done after exactly four hours
Protein makes the part of the brain that works to preserve memory stronger.
However, the study says, much depends on how long the protein is released.
They say that it is not immediately after or after the study, but if this exercise is done after a few hours, it helps the most to remember that reading.
72 people were collected for this study. They first studied for 40 minutes.
These are then divided into three groups. Members of a group began to exercise immediately after reading. The second group exercised four hours after studying. The third group did not do any exercise.
The members of the first two groups cycled and exercised for about 35 minutes.
Two days later, all three of these groups were tested to see how well they remembered each other.
The second group, those who exercised four hours after the study, were found to have the best memory.
MRI shows the part of the brain - the hippocampus, which works to remember something - the sharpest and freshest in the brain of the second group.
The idea is that the chemicals that are produced in the body as a result of exercise - such as dopamine, norepinephrine, can help to strengthen the memory.
The study was led by Guillen Fernandez, a scientist at the Dunders Institute for Brain, Cognition and Behavior in the Netherlands.
He said the results of their tests showed that exercising over time could improve memory in the long run.
It is also possible to strengthen the weakened memories.
However, the mystery of why exercising after a few hours is good for memory is still not clear.
