Decoding the Date of Oldest Recorded Solar Eclipse

03 Nov 17

A solar eclipse is a kind of eclipse that occurs when the Moon passes between the Sun and Earth. During solar eclipse the Moon fully or partially blocks the Sun just for a time being. It happens only at new moon when the Sun and the Moon are in conjunction as seen from Earth in an alignment called syzygy.The oldest solar eclipse that was not recorded has been marked by scientists.

There is a reference of solar eclipse in the holy Bible dated October 30, 1207 BC. It has created a chronology regarding that. There have been mythological instances associated with solar eclipse. The scholars have been trying to get the meaning of the text and come up with the meaning that “text to mean that the sun and moon stopped moving.” However, some scholars say that there can be other meaning of the text like “sun and moon just stopped doing what they normally do: they stopped shining” it might not be the eclipse exactly.

Earlier historians claimed that it was not possible to investigate this possibility with calculation. Now the researchers developed a new eclipse code, which takes into account variations in the Earth's rotation over time. With these calculations, scientists speculated that the only solar eclipse that was first visible from Canaan was on October 30, 1207 BC.

Mumbai City FC Coach Guimaraes Unhappy with Referee Pranjal Banerjee

18 Jan 18

India is famous for its sports. Football is India’s second most popular game. It is played extensively in the country, with the maximum fan following in Goa, Kerala, West Bengal, Mizoram, Manipur and Sikkim.

In ISL 2017/18, Iain Edward Hume, a Canadian footballer striker for Kerala Blasters scored the only goal of the night as Kerala Blasters registered an important achievement against Mumbai in January 14’s crunch ISL encounter. While Mumbai's players were still taking their respective positions, Kerala's goal amazed them. However, the referee too was not ready for the game. Before the team could realise anything, Pekuson spontaneously released Hume who kept the ball past keeper, Amrinder. Mumbai City FC coach, Alexandre Guimaraes was shocked and speechless. He was extremely angry and sad. He felt that it was very unfair on the part of the referee to let the goal stay under unsure circumstances. Moreover, in the second half, Mumbaikars managed to give back the similar shot but unfortunately Keralites blocked it completely. Considering the fact that managers have been suspended earlier for keeping their opinion on matters like this, Mumbai's coach said he would not comment on this. However, he said that Mumbai team played well and gave their best but failed to finish off their moves. He continued saying that the team tried to follow their style and managed it well. The team handled well apart from making efforts to somehow draw the game. Every game comes with risks and uncertainty and something similar happened.

Research Unveils Unknown Population of Ancient Native Americans

18 Jan 18

A new study performed by the University of Alaska Fairbanks has revealed a previously unknown population of ancient people in North America. The researchers named the new group as 'Ancient Beringians.'

The research involved the genetic analysis of ancient DNA from a 6-week-old infant named "Xach'itee'aanenh T'eede Gaay" found at an Interior Alaska archaeological site. She and a younger female infant named "Ye?kaanenh T'eede Gaay" lived about 11,500 years ago and have similarities like first cousins. This analysis made the scientists infer that about 35,000 years ago, single founding ancestral Native American group split from East Asians. Then, about 20,000 years ago, that group split into two groups: the Ancient Beringians and the ancestors of all other Native Americans. The findings of the research also suggested two new scenarios for populating the New World. The first one being that there were two distinct groups of people. They crossed over the Beringian land bridge 15,700 years ago. The second is that one group of people crossed over the land bridge. It then split in Beringia into two groups: Ancient Beringians and other Native Americans. The scientists expected that the genetic material would match the genetic profile of other northern Native American people. Surprisingly, it matched no other known ancient population. They concluded that the Ancient Beringian people remained in the Far North for thousands of years. The DNA results suggest that around 6,000 years ago, the Athabascan ancestors replaced the Ancient Beringian population and established deep roots in their ancestral lands.

Study Explains Why Mammals Prefer To Cradle Babies on the Left

17 Jan 18

A new study found out that humans and primate mothers prefer to cradle their babies in the left arm as opposed to the right one. There was a strong bias that was explained by the dominance of the right hemisphere of brain in social processing. Apparently, signals from the left eye are received by right half of the brain so the bias for left side eventually leads to more effective monitoring of visual cues. This would help in picking up facial expressions and thus, promoting a much better mother-baby bonding.

 The preference of left side in mother-infant bonding has now been studied in 11 different species of free ranging marine and terrestrial mammals. Kangaroos, antelope, reindeer, infant whales were among the many that were studied. Another important point to note was mothers showing this preference more during the times of stress. Both mother and baby pick up these visual cues from their right hemisphere. The right hemisphere promotes optimal processing of social information and helps in understanding many aspects of social behaviour.

 The research was led by Andrey Giljov, Yegor Malashichev and Karina Karenina from St.Petersburg State University in Russia. They conducted around 11 research expeditions spanning different continents between 2012 and 2016. The study has helped in understanding how we have evolved and our behavioral traits.
