The wall didn't know, the mobile has ears!

 The wall didn't know, the mobile has ears!

We often listen, the wall also has ears. This saying is often used as a warning to be careful when having sensitive or confidential conversations. But in the current digital age, this has started to be experienced as a reality. It is not clear that the wall has ears, but many are now curious about whether the mobile is listening to us.

Many of us have experienced that after we talk to friends or family about a product or service, the related advertisement appears on the mobile. Therefore, many people now have the question, "Do our phones or apps really listen to our conversations?"

What is the fact that the mobile listens?

According to studies and experts, under normal circumstances, your phone does not listen to you constantly. However, some apps or voice assistants (such as Google Assistant, Siri) only activate and listen to audio after hearing a 'wake word' such as "Hey Siri" or "OK ​​Google".

Why do we see advertisements for the same product or service that we are talking about?

Rather than our phones constantly listening and showing us ads as we might expect, ads are targeted based on our internet usage, search history, location, and social media activity. That’s why sometimes ‘what we’re talking about’ and ‘ads in our feed’ coincidentally match.

How to check if your phone is listening to you

You can easily check if your phone is listening to you.

1. Think of a topic that you’re not normally interested in. No matter why you’re not interested, there’s no record of any previous searches, website visits, or conversations related to the topic.

2. After choosing a topic, sit close to your phone and talk about it. Use keywords related to the topic as much as possible. For example, if you think of the topic “boat engine,” say things like “where can I buy a boat engine?”, “which boat engine is reliable?”, “how much does a new boat engine cost?” Your words should clearly indicate a desire to buy an engine. Talk like this for a few days.

3. Then evaluate the ads that appear in your feed. This includes ads from platforms like YouTube videos, Google search, and social media feeds. If you start seeing ads related to boat engines or boats, your phone is listening to you.

What can we do?

Permission control: Go to your phone's settings and remove access from apps that don't require the microphone.

Turn off voice assistants: Disable services like Google Assistant or Siri when not in use.

Be aware: Don't install unnecessary apps, and read privacy policies when installing apps.

According to studies and experts, your phone or apps are not constantly listening to you. However, apps or voice assistants that have received microphone permission can listen to your commands. For this reason, we need to make it a habit to manage permissions consciously, turn off unnecessary services, and read privacy information.

What is Alpha School in America, where AI teaches instead of teachers!

 What is Alpha School in America, where AI teaches instead of teachers!

What comes to mind when you think of ‘school’? Surely, for many, classrooms from kindergarten to 12th grade, front-line teachers, and long lessons come to mind. This is how schools have been set up for centuries. But now, as AI is changing our lifestyle, the traditional way of learning and schooling has also started to take a new form.

Alpha School, located in Texas, USA, has become a global sensation due to its unique and modern way of teaching students. Instead of a teacher teaching 25-40 students at a time as per the traditional style, it is said that in this school, students are instructed individually by AI guides. It is said that the AI ​​system also analyzes their progress and provides immediate feedback, which helps them improve their weaknesses.

At Alpha School, students are said to have to study for only 2 hours a day. According to international media, after two hours of study, Alpha School students spend time on physical activity, problem-solving activities, leadership exercises, and life skills. These include activities ranging from long bike rides to creative projects and entrepreneurship training.

Another feature of Alpha School is its financial rewards system. Students are said to earn money for completing assignments, projects, or mastering skills, which they can spend on their own projects or interests, or even invest.

According to international media, Alpha School is not a school that appeared overnight or became famous. It has been operating on campuses in Texas, Florida, and California for more than a decade, and is now preparing to expand to New York City. It is said that a new Alpha campus is planned to open in Manhattan next September, with annual tuition fees ranging from $40,000 to $65,000, depending on the location.

This unique and technological teaching style demonstrated by Alpha School has shown the potential for education to take on a completely new form through innovation, not just limited to books and teachers.

What are the procedures for postmortems and identification of those who died in the protests?

 What are the procedures for postmortems and identification of those who died in the protests?

Coordination between forensic science, police, and hospitals is necessary to identify and determine the cause of death of those who died during the protests.

An official letter of medico-legal examination from the police is required before the postmortem is conducted, which confirms the cause of death.

DNA analysis and other scientific methods are used to identify bodies that have been burned, but identifying completely burned bodies is challenging.

Violent incidents during protests cause great human loss. In such incidents, a complex and sensitive procedure is adopted to identify and determine the cause of death of those who die due to gunshots, fire, or other injuries.

Coordination between forensic science, as well as the police, and hospitals is very important to identify and determine the cause of death of the deceased. This process is sensitive from both a scientific and legal perspective.

Incident and initial procedures

People who die during the protests are often taken to the hospital immediately by eyewitnesses or friends. The name of the deceased is registered in the hospital and treatment is attempted. If the person is confirmed not to be alive, the body is sent for postmortem. Tribhuvan University Teaching Hospital, Kathmandu is a well-equipped centre for mortuary storage and postmortem. The body is preserved in a freezer facility. The teaching hospital has the necessary equipment for proper management of the body and postmortem, which makes the process systematic.

Identification process of the deceased

Initial identification

The identity cards, jewellery or other personal belongings of the deceased form the initial basis for identification. The name and address of the deceased can be ascertained from such items. If such items are not available, the relatives come to the hospital and identify the body.

Personal belongings are of great help in the identification process, but sometimes other scientific methods have to be used in cases where these items are destroyed.

Notification to relatives

Once the details of the deceased are registered in the hospital, the relatives are informed. The hospital maintains a list of the names of the deceased, which the relatives look at to identify the body. Once the identity is confirmed, the postmortem process proceeds.

Postmortem and medico-legal process

A medical-legal examination is required from the police before a postmortem can be conducted. In cases where police stations are affected, such a letter is issued by the Kathmandu Police Complex. A postmortem determines the cause of death, such as gunshot wounds, injuries or fire. This process is important for the relatives of the deceased and the community to uncover the truth.

The main causes of death during the protests currently include gunshot wounds, internal injuries, head injuries or fire. In cases of gunshot deaths, doctors analyze the nature of the bullet and the damage to the body.

Identification of people who died in a fire

The identification of bodies that died in a fire is complicated. For example, in the case of seven people who died in a fire in Bhatbhateni, identification is challenging. Methods such as presumptive identification and DNA analysis are used to identify burned bodies. If jewelry, clothes or other personal belongings are left, they can be used to identify them.

DNA Analysis

When a body is not completely burned and some tissue remains, DNA is extracted and analyzed. This process is carried out at the Central Forensic Science Laboratory of the Nepal Police. DNA analysis can confirm the identity of the deceased, but this process is time-consuming and resource-intensive.

DNA Analysis Process

DNA Extraction

DNA is extracted from white blood cells, because red blood cells do not have a nucleus. DNA can be extracted from bones or teeth in burned bodies, if they are not destroyed.

Polymerase Chain Reaction (PCR-M)

If the amount of DNA is low, the amount of DNA is increased by the PCR-M process. This makes it easier to analyze the DNA sequence adenine, guanine, thymine, cytosine.

Profile Matching

The DNA profile of the deceased is compared with the DNA of his father or mother. A 50 percent match between the father or mother's DNA confirms the identity.

Challenges in completely burnt bodies

If the body is completely burnt and the tissues are destroyed, DNA analysis is not possible. In such a case, identification becomes impossible. Also, if the relatives of the deceased do not contact them in time, the process becomes more complicated. The possibility of identifying completely burnt bodies is limited, but we must make the most of the resources and technology available.

This process is not only to identify the deceased and determine the cause of death, but it is also a means of ensuring truth and justice in society. Such sensitive processes provide comfort to the victim’s family and provide truthful information to society.
