For the first time, scientists have been able to explain why humans have a more evolved brain than other species.

At the DNA level, humans share 99 percent and 98 percent sequence similarity with Chimpanzees and Gorillas, respectively. But surprisingly our brain is about three times bigger than that of these apes. In fact, of all primates, we possess the largest brain. Scientists have long wondered why humans have such developed brains compared to other species. Since ancient times, many experts have attempted to address this question from different perspectives.

However, a group of scientists at the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, UK, recently discovered a more obvious answer to this mystery. …


How can you argue with a fake smile pressing your “buy button”?

Some days earlier, while I was looking to buy a couple of items from a department store, I noticed some toothbrushes. The toothbrushes seemed very elegant and stylish. I just picked a light blue toothbrush in my hand at random and wondered about which color to choose. At that time, a salesman approached with a smiley face and said, “I also use this toothbrush of the same color.” I ended up buying the light blue toothbrush due to the influence of liking bias.

Scientists are attempting to trick the coronavirus in such a way that it will not enter our cell.

SARS-CoV-2 enters our cells via ACE2 receptor protein found on the cell surface. This entry is initiated by the binding of ACE2 with the spike (S) protein of this virus. Scientists have introduced an idea to deceive coronavirus by using this binding affinity.

Since the beginning of the COVID-19 vaccine production effort, researchers are adopting various approaches to prevent this binding. Some researchers are producing monoclonal antibodies to occupy the binding site of ACE2. On the other hand, other groups of scientists are trying to find a vaccine that will trigger our body to produce antibodies on its own.

In the past, there have been instances where early delivery of vaccines has been a colossal failure.

The entire world is agitated by the COVID-19 pandemic. For a long time, people have been unable to breathe in the fresh air. The world’s economy is crashing down. The burden of billions of dollars of debt on governments is mounting. Unemployment and poverty are on the exponential rise throughout the world. Everyone is expecting that a vaccine will soon bring to an end to the darkness of this pandemic.

Researchers across the world are striving to create the vaccine against SARS-CoV-2 —…

Bubonic plague is the disease that triggered “Black Death” — the deadliest pandemic in human civilization — makes people scared from the history books. In mid-1300s, around 60 percent of the population in Europe were killed by this disease. Recently, a few new cases of this plague have been reported in China and the United States. Amid COVID-19 pandemic, which is sparking a new paranoia among the common people.

According to Chinese Health ministry, last month 15-year-old boy has died of bubonic plague in western Mongolia after eating an infected marmot. The plague was also detected on July 5 in…

The life is full of ambiguity and dilemma for everyone. Every day, we have to get into some kind of confusing situation when making decisions on various matters. Many of these decisions may be trivial and insignificant — but in some cases, we ought to make a prudent move because it can have a severe impact on our lives.

For example, which field should I pick as a career, during shopping — which color of the dress will suit me perfectly, do I step into that particular relationship, and so…


Through comparative genomic analysis, researchers have explained that SARS-CoV-2 is not a laboratory construct or a deliberately engineered virus.

Since the first case was identified in China in November 2019, about 724K people worldwide have died of coronavirus disease. While health workers and scientists throughout the world are striving to control its transmission and develop a vaccine, a group of people strongly suspect that the virus has been created as a biological weapon in the laboratory. …
