The Dhaka Times Desk Scientists have found the possible source of the Sun's magnetic field. Until now, where they thought the possible source of the magnetic field was, it was not actually there.
The discovery, using complex computer simulations, suggests that the Sun's magnetic field originates not from deep within the star, but from plasma instabilities across the outer layers of the solar surface. As researchers previously thought.
A report of Live Science informed this information. If the scientists' hypothesis is correct, their discovery could lead to a better chance of predicting solar flares and solar storms, the report said.
Solar flares are basically intense bursts of electromagnetic radiation in the Sun's atmosphere. These explosions often occur in active regions of the Sun. Because of this, power outages can occur on Earth, Internet systems can be paralyzed, and even satellites can crash into Earth.
The researchers published their results in a study published in the journal Nature on May 22. However, Keaton Barnes, a researcher at the Massachusetts Institute of Technology, said that I think this result can be controversial.
Giant plumes of solar flares can travel up to several million miles per hour, scientists say. Charged particles from the solar wind disperse and create a wavefront, which can also trigger geomagnetic storms on our planet when they reach Earth.
Previously, researchers weren't sure where most of the Sun's magnetism comes from. But the new study also offers hope for better understanding and predicting solar storms.

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
