Eruptions on the sun come in different sizes and shapes, from long jets to massive explosions called CMEs (Coronal Mass Ejections). It was previously believed that these were driven by varied processes.

Scientists from NASA’s Goddard Space Flight Center have now proposed a universal mechanism which can explain the entire range of solar eruptions.

Their study was based on the high-resolution observations of filaments from NASA's SDO (Solar Dynamics Observatory), and the joint NASA Hinode / Japan Aerospace Exploration Agency satellite.

For long they had known that the onset of CME eruptions is linked to filaments. Now, the improved observations revealed that the onset of jets too is accompanied by filaments.

The scientists refer their proposed mechanism for the way these filaments cause eruptions as the “breakout model”. Because, the stressed filament persistently pushes at its magnetic restraints and eventually breaks through it into space.

Their computer models to reproduce jets in the computer simulations which were replicas of the space observations, suggesting that jets and CMEs happen similarly.

"With this mechanism, we can understand the similarities between small jets and massive CMEs, and infer eruptions anywhere in between" says the study-lead.

A Sight to First Round Table Conference

The Surprising Facts of Sledge Hockey

15 Dec 17

Para ice hockey is also known as ice – sledge hockey. In the United States of America, it is known as sled hockey. It is a sport that was specifically structured to allow participants with physical disability to play the sport of ice – hockey. The game was invented in the early 1960s in Stockholm, Sweden. It was basically invented at a rehabilitation centre.

Sledge Hockey is a well-known sport in the Winter Paralympic Games. The international governing body for sledge hockey is the International Paralympic Committee. The committee has also officially changed the game’s name to “Para ice hockey” and it in consideration since 30th November, 2016. The Committee changed the name because of the fact that the meaning of sledge differs between languages. The history of sledge hockey recalls that two men from Sweden prepared the sledge for Para ice hockey because they wanted to continue playing hockey despite their physical disability.

Origin and Growth of Women’s Football in India

14 Dec 17

Women’s football in India is growing more and more popular day by day. In India, women’s football team was administered by Women's Football Federation of India (WFFI) from 1975 until the early 1990s. Later, it was absorbed into the All India Football Federation (AIFF). This team represents India in women's international football competitions. The women’s football has not had the kind of start as the men’s game has. It has also not seen that kind of expansion in the country as its male counterpart. This may be attributed to the impassive attitude of the AIFF and its inability to raise sufficient funds. The game has its early pioneers in the state of West Bengal. In the India women's football championship, women’s national competition is played on a state vs. state basis.

For the junior teams, there are other national championships such as Junior Girls National Championship (for under 19s) and Under-17 Girls National Championship. In June 2009, the women’s game saw its lowest point, when FIFA delisted the side from world rankings for being inactive for more than 18 months. The aim of the AIFF for women's football from 2014 to 2017 was to improve the ranking of the Indian senior team, start a professional women's league by 2015, and to qualify for U19 as well as U16 versions of the AFC championships. Some of the internationally recognised faces in women’s football are Chitra Gangadharan, Jaanki Kotecha, Sujata Kar, Alpana Sil etc.

Human Dispersal Out of Africa- The Revised Story

14 Dec 17

There are numerous theories of human evolution and dispersal. One such model is the “Out of Africa Model”. According, to it about 60,000 years ago, the modern humans evolved in Africa and then dispersed in Asia and reached Australia in a single wave. However, this model seems to be reversed by a recent research conducted by Max Planck Institute for the Science of Human History and the University of Hawai'i at Manoa.

This research establishes that prior to 60,000 years ago, humans left Africa multiple times. They interbred with other hominins such as Neanderthals and Denisovans, in many locations across Eurasia. This research was conducted by making use of fossil identification techniques and technological advances in DNA analysis. The research also found that all present-day non-African populations evolved from a single ancestral population in Africa approximately 60,000 years ago. This shows that around 120,000 years ago, there were multiple, smaller movements of humans out of Africa. It is estimated that the present day non-Africans have 1-4% Neanderthal heritage, while another group has estimated that modern Melanesians have an average of 5% Denisovan heritage. This establishes that modern humans had numerous interactions. This also confirms that the spread of material culture is more complex than estimated. The new research has put forward many questions that need answers. The authors wish to conduct new researches in many areas of Asia where none has been done till date. These researches prove useful in filling the gaps in evolutionary records.

A Not Out Cricket for Kids in Australia- An Initiative to Make Sports More Interesting

13 Dec 17

The Australian Cricket has given many relaxations to the rule book for young players in an initiative to use the fun of backyard cricket as the motivating factor of its junior program. Various steps have been taken in this regard. Giving a try to make the game little easier the junior teams are made smaller and pitches are made shorter.

Most of the cricket specialists think that backyard cricket rules are the better way to teach children the technique of game. The changes have been done under the guidance of Dr. Renshaw, father of Australian batsman Matthew Renshaw. He says that there should not be limitation of time or overs to play. The kids should play till they want to play in their natural way. The more they will play the better player they will become in future. Cricket Australia has taken the initiative to make the game more enjoyable so that kids do batting, bowling and fielding for longer periods. Under this new format of junior cricket, Games are made shorter, by cutting from 30 to 20 overs, in a 40-metre boundary of ground. Now it is made sure that everyone is given a fair chance to bat, bowl, field, and wicket-keeping every week. These all changes are commendable but the most interesting part is that, in this new format nobody will be declared out. Children will be made familiar with the rules and real techniques of cricket with their growing age.
