The Dhaka Times Desk Mars is a planet that raises issues that could be useful in the future for the search for life beyond Earth or for human habitation. And in this case, the first planet that comes to mind is Mars.
Scientists say that 3.5 billion years ago, the atmosphere of Mars was very thick. The temperature was much lower than now. The stream of water flowed through the soil.
Even the north of Mars was hundreds of meters deep, an entire ocean. Scientists are of the opinion that the water reserves disappear during the outbreak of solar storms. Some of its remnants are now visible in the polar regions of Mars. This water is currently located as a layer of ice under the surface of Mars. That is, there is an entire ocean of water under the ice!
To determine how Mars evolved from an Earth-like habitable planet to its current state, scientists used technology to map Mars' past.
However, some scientists believe that the topography of Mars is more complex than that of Earth. They claim that mud is usually formed from the reaction between water and minerals on earth. Other minerals are produced from it. Again, when the reaction between water and iron or magnesium occurs, the water dries up and leaves salt. However, there are salts on the chest of Mars, which are formed before the mud layer.
Not only that, research is also being carried out to find out whether the presence of water on the chest of Mars was long-term or if it was temporary, disappeared and re-emerged. The OMEGA instrument aboard the European Space Agency's Mars Express spacecraft is providing scientists with detailed information about the topography of Mars. And scientists are verifying those data.

How to prevent dengue
Dengue is a mosquito-borne viral fever. This fever is different from other viral or bacterial fevers. However, this fever is not contagious in any way. This viral fever can occur alone or in combination with other viruses (chikungunya, yellow fever, Burma forest, flu, respiratory syncytial) and bacteria (pneumococcus).
Dengue fever is divided into two categories depending on the severity of symptoms and fever.
1. Common dengue fever
2. Dengue fever with bleeding.
In the case of common dengue fever, the following symptoms are mainly seen-
1. Sudden high fever lasting 2 to 7 days.
2. Severe headache.
3. Pain behind the eyes.
4. Along with the fever, red rash appears all over the body.
5. Severe pain in whole body as well as back pain.
6. Nausea or vomiting.
7. A rash or red bumps on the skin.
In case of dengue fever with bleeding:
1. Bleeding from nose, mouth or vomiting with high fever within 2 to 48 hours.
2. Fluid accumulation in chest or abdomen along with fever.
If any of these symptoms appear, seek medical attention immediately.
On the other hand
Wait at home for the first 3 days of fever. On the other hand, sponge the whole body with water every now and then. This will reduce the level of fever. Drink enough water and rest. After that, if the fever does not decrease or if it continues to increase after some time, consult a doctor immediately.
Things to do to prevent Dengue:
1. Try to keep the surroundings of the house as clean as possible.
2. If there are flower tubs or broken plastic bottles, can shells, tires or polythene inside the house, clean them quickly and drain the accumulated water from the flower tubs.
3. Spray or fog at least 3 times a week to kill mosquitoes.
4. You can keep mosquito repellent cream with you while going out.
5. After evening, younger and older members of the household should use mosquito nets.
6. Clean up any accumulated rain water, as this is the time when Aedes mosquitoes lay their eggs.
7. On the other hand, you can use mats along with mosquito nets to avoid mosquito infestation.
8. Since Aedes mosquitoes bite during the day, it is important to avoid sleeping with mosquito nets while sleeping during the day. Source: https://dmpnews.org
