Childhood stress makes brain mature

Stress in early childhood due to negative experiences may lead to faster maturation of certain brain regions, during adolescence, a new study suggests.
The study found that these experiences cause faster maturation of the prefrontal cortex and amygdala- that also play a role in the control of emotions, in adolescence.
“From an evolutionary perspective, it is useful to mature faster if you grow up in a stressful environment. However, it also prevents the brain from adjusting to the current environment in a flexible way.
In contrast, stress experiences later in life such as low peer esteem at school, is connected to a slower maturation of the brain area hippo-campus and another part of the prefrontal cortex in teenage years, the researchers added.


All about Facebook

Facebook has become the giant platform which has revolutionized the every sector of economy and country.

Nowadays, Facebook has become the No.1 social network with which anyone can share anything like their day-to-day life, Pictures, and media too.

Facebook was made by the person named “Mark Zukerberg”. Due to good programming skills and knowledge, he at last made it and now he is earning millions.

Now, Facebook is working on to build an AR (Augmented Reality) based project, which could give boost to the gaming sector, as more number of consoles, games and AR headsets would be sold out.

At last, I would conclude that with the help of Facebook we can connect with our friends, families and relatives.

But there are some demerits of it also. One can easily steal someone’s private information and even hack their account.


It’s the need of an hour to look after your school going children


Three days ago, a post was published on Tribune newspaper, related to child bullying. They said ” Childhood bullying may up heart disease, diabetes risk”.

Parents have become so busy in their life and earning for their family. But they even forget to look after their kids for whom they are working hard day and night.

The chances are bullying can happen to any student. Children who are bullied may experience lifelong health effects related to chronic stress exposure such as increased risk for heart disease and diabetes in adulthood, new research has found.

“Bullying, as a form of chronic social stress, may have significant health consequences if not addressed early. Bullying has long lasting impact on physical health too.

According to me, Bullying is more severe and painful than physical pain. Stress can cause imbalance in hormonal and metabolic processes in the body.

Chronic stress may also impair the child’s ability to develop psychological skills that foster resilience, reducing their capacity to cope with future stress.

Thales of Miletus, who in the 6th century BCE said that every observed phenomenon probably had a perfectly natural explanation. The came Nicolaus Copernicus who made the heliocentric theory which explains that sun is at the middle of the universe.

 Einstein later, and this is why many considered him to be the ” Father of modern science”.

What’s a Blackhat Hacker?

This content is taken from the magazine PC magazine dot com. A black hat hacker is an individual with extensive computer knowledge whose purpose is to breach or bypass internet security. Black hat hackers  are also known as crackers or dark-side hackers. The general view is that, while hackers build things, crackers break things. They are computer security hackers that break into computers and networks or also create computer viruses. The term “black hat” comes from old westerns where the bad guys usually wore black hats and the good guys wore white ones.

White hat hackers also identify security weaknesses; but, instead of performing malicious attacks and theft, they expose the security flaw in such a way as to alert the owner that there is a breach so they can fix it before a black hat hacker can take advantage of it. Though they often start out as black hat hackers,  white hat hackers sometimes are paid consultants or actual employees of a company that needs its systems protected. Other types of hackers include: blue hat hackers & gray hat hackers.  Blue hat hackers are security professionals that are invited by Microsoft to expose vulnerabilities in Windows products.
