New studies publised in Nature reveal, Indus era is 8,000 year-old and older than Egyptian and Mesopotamian civilization

According to this study Egyptian civilization began in 7000bc-3000bc and Mesopotamian began in 6500bc-3100bc which much later than Indus Valley Civilization

  • Indus Valley civilization is 5000 years older than previously thought
  • The study is done using a new carbon dating technique
  • Scientists from IIT-Kharagpur and Archaeological Survey of India (ASI) conducted the study, published in journal ‘Nature’ last week (May 2016)

A study -published last week (May of 2016) in the reputed journal ‘Nature’ by a group of researchers in India shows that the Indus valley civilization is 5000 years older than what we previously perceived. This study was done using a new carbon dating technique on animal fragment and pottery fragments.

According to this study, Indus valley civilization is even older than Mesopotamian and Egyptian civilizations.

The study was conducted by scientists from IIT-Kharagpur and Archaeological Survey of India (ASI). The study shows that the mature Indus valley civilization began in 8000bc to 2000bc and not 2600bc to 1600 and it pushes pre harappan civilization to 9000bc to 8000c. Egyptian civilization began in 7000bc to 3000bc and Mesopotamian began in 6500bc to 3100bc which much later then Indus Valley Civilization according to this study.

“Our study pushes back the antiquity to as old as 8th millennium before present and will have major implications to the evolution of human settlements in Indian sub-continent,” Anindya Sarkar, a professor at the department of geology and geophysics at IIT-Kharagpur, said in a statement.

Sankar .who also worked with the researcher from ASI in the Physical Research Laboratory in Ahmedabad and Pune’s Deccan College. They even used a technique known Optically Stimulated Luminescence in this study. In this technique the amount of light emitted from mineral grains to date past events can be measured.

This study has also given a new theory as to how Harappan civilization must have declined. Earlier it was believed that the civilization got declined because of climate change.

But according to the new theory climate change did play a role but it is not the main reason behind the declination harappan civilization. It had more to do with the change in cropping patterns and storage of grains.

“Our study suggests that the climate was probably not the sole cause of Harappan decline. Despite the monsoon decline, the civilisation did not disappear. The people changed their farming practices.

“They switched from water-intensive crops when monsoon was stronger to drought-resistant crops when it was weaker. Our work shows they did not give up despite the change in climate conditions,” said Anindya Sarkar of the Department of Geology and Geophysics, IIT Kharagpur and the lead investigator.

“Our study suggests that other causes, like change in subsistence strategy, by shifting crop patterns rather than climate change was responsible for the Harappan collapse,” Sarkar said.

Drinking Too Much Water Can Harm You

Do you drink too much water? Beware, overhydration — excess fluid accumulation — can lead to dangerously low sodium levels or in the blood or result in brain swelling, researchers say.

Hyponatremia, a life-threatening condition of brain swelling, is more common in elderly patients and can cause cognitive problems and seizures.

“(Hyponatremia) occurs in common pathological conditions, including brain injury, sepsis, cardiac failure and in the use of drugs, such as MDMA (ecstasy),” said Charles Bourque from the McGill University in Canada.

While it was yet uncertain how hyponatremia develops, the study found that a defect in the hydration sensing mechanism of the brain could be the culprit.

The researchers said that brain’s hydration sensing neurons could not detect overhydration in the same way that they detect dehydration.

Overhydration activates Trpv4 — a calcium channel that can be found in glial cells, that act to surround hydration sensing neurons.

It is cellular gatekeeper implicated in maintaining the balance of water in the body.

“Our study shows that it is in fact glial cells that first detect the overhydrated state and then transfer this information to turn off the electrical activity of the [hydration sensing] neurons,” Bourque explained.

“Our specific data will be important for people studying hydromineral and fluid electrolyte homeostasis, and clinicians who treat patients faced with hyponatremia,” he noted.

The results, published in the journal Cell Reports, showed that overhydration is first identified by the Trpv4 channel which triggers the release of a type of amino acid known, taurine, which acts as a trip wire to inhibit hydration sensing neurons.

“Preclinical models of hyponatremia will be used to examine if the mechanism we report is affected in this condition with the long-term objective of designing new treatments or diagnostic tools,” Bourque added. (IANS)
