The Dhaka Times Desk Many people lose the ability to speak when paralyzed. There is no way to contact them. But this time, with the help of artificial intelligence, the paralyzed will speak.
Experiments have been going on for a long time with devices to communicate with the paralyzed. Recently artificial intelligence has also shown us a solution. By implanting an artificial intelligence chip in the human brain, they can easily be given the opportunity to speak.
A recent experiment with such a chip on two paralyzed women was successful. One of them had amyotrophic lateral sclerosis or ALS. Another had a brain root injury. Although they had problems with pronunciation, they remembered well how to pronounce words. The artificial intelligence chip is capable of recognizing 60-78 words per minute by checking the coordination of neuron activity with facial expressions. The success rate is faster and more accurate than any previous device.
Recently, the news of these two tests is available in two separate papers in the journal Nature. Professor Frank Willett of Stanford University's Neural Prosthetic Transnational Laboratory said, 'In the future, even if someone is paralyzed, they will be able to express their thoughts very easily. Major obstacles to their expression will be removed.'
Normally a healthy and normal person can utter 160 words per minute in English. As such, this artificial intelligence is still somewhat lacking. Still, it is seen as a major breakthrough for medical science. This new artificial intelligence device is called Brain-Computer Interface or BCI. After BCI collects neuron signals from the brain, it sends commands to an external device. The use of this system will also increase the opportunity to use robotic arms or parts.

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
