Scientists from Tohoku University in Japan have claimed that Silicon (Si) is the ‘missing element’ in the Earth’s core. This discovery could help us to better understand how our world formed.
According to them silicon likely makes up a significant proportion of Earth’s core after its major constituents iron and nickel. It was missing element in the deep interiors of our planet that has eluded us for decades.
- It was found that silicon is a major element and constitutes about 5% of the Earth’s inner core by weight. It could be dissolved into the iron-nickel alloys.
- For the study, scientists recreated the high temperatures and pressures found in the deep interior of the Earth’s core. They recreated alloys of iron and nickel and mixed them with silicon.
- They then subjected these alloys to the immense pressures and temperatures that exist in the inner core.
- Scientists discovered that this mixture matched what was seen in the Earth’s interior with seismic data.
Note: The innermost part of Earth i.e. core is thought to be a solid ball with a radius of about 1,200 kilometres. It is far too deep to investigate directly, so scientists study this region’s make-up using seismic wave. Earth’s core is mainly composed of iron (makes up about 85% of its weight) and nickel (accounts for about 10% of the core).
India was ranked 92nd among 118 countries in the 2017 Global index of talent competitiveness (GTI) list. The index measures ability of countries to compete for talent i.e. how countries grow, attract and retain talent.
The index is produced by global business school INSEAD in partnership with Adecco Group and Human Capital Leadership Institute (HCLI) of Singapore.
Key Highlights of 2017 GTI
- Top 10 Countries: Switzerland (1st), Singapore (2nd), United Kingdom (3rd), United States (4th), Sweden (5th), Australia (6th), Luxembourg (7th), Denmark (8th), Finland (9th) and Norway (10th).
- BRICS Countries: India’s ranking is worst among the five BRICS countries. China (54th), Russia (56th), South Africa (67th) and Brazil (81st).
- It noted that BRICS countries are not getting stronger and both China and India have slipped from their year-ago rankings.
- India Related Facts: In this edition of the list, India slipped by 3 places compared to 89th rank in 2016 GTI.
- India stood on a relatively solid in pool of global knowledge skills compared with other emerging markets. But in terms of retaining and attracting talent indices, India ranked lowly 104th and 114th, respectively.
- Overall a major challenge for India is to attract talent from abroad, particularly in the context of large emigration rates of high-skilled people.
- India has been able to create a stable pool of global knowledge skills, but still experiences a brain drain. India’s ranking will improve only if it improves in its regulatory (94th) and market (99th) landscapes.
- GTI global ranking of cities: 2017 edition of GTI also released the first-ever global ranking of cities on the basis of their reputation and growing footprint in attracting, growing, and retaining global talent.
- Top 10 global cities in terms of talent competitiveness: Zurich, Helsinki, San Francisco, Gothenburg, Madrid, Paris, Los Angeles, Eindhoven and Dublin. Mumbai was only Indian city to make into this list.
