Vidyarthi Vigyan Manthan 2020-21:
- VVM is an initiative of Vijnana Bharati (VIBHA), in collaboration with Vigyan Prasar, an autonomous organization under the Department of Science and Technology, Government of India and National Council of Educational Research and Training (NCERT), an institution under the Ministry of Education (earlier known as Ministry of Human Resources and Development).
- VVM is a national program for popularizing science among school students of standard VI to XI, conceptualised to identify the bright minds with a scientific aptitude among the student community
- Health and Family Welfare Minister Dr Harsh Vardhan launched ‘Vidyarthi Vigyan Manthan, 2020-21. This initiative is a national programme for popularizing science among school students of Class 6th to 11th. It was designed to identify the bright minds with a scientific aptitude among the student community.
- To create interest among students in pure science
- To educate school children about India’s contributions from tradition to modern, to the world of science and technology
- To provide hands-on training to students through workshops and other events
- To provide mentors for preparing students to carry forward their education in the field of science
- To conduct competitive tests to identify students who have a scientific bent of mind
- To identify successful students at the State and National levels and felicitate them
- To organise exposure visits for the winners to various R&D institutions in the country
National Bone & Joint Day:
- Bone and Joint day is celebrated all over India by the Indian Orthopaedic Association (IOA) and all its state chapters on 4th of August every year since 2012.
- The primary aim is to create awareness among people about the bone health, various orthopaedic illnesses which can be prevented or treated and be useful to the society.
- This year the theme of observing the day is ‘Prevention of deformity in degenerative disease’.
- Necessary steps to help to prevent having these deformities and improve the outcome of the treatment are:
- Maintaining an ideal weight
- Healthy diet Regular weight bearing exercise
- Weight bearing exercises
- Improve muscle strength
- Avoid overuse or misuse of the joint
- Use of appropriate braces Avoid joint injuries
IIT Kanpur develops indigenous seed balls BEEG for farmers:
- IIT Kanpur has developed indigenous seed balls named BEEG (Bio -compost Enriched Eco-friendly Globule) which will help people and farmers in plantation with safety in Corona times and will also provide employment to people.
- The BEEG is developed in collaboration with Agnys Waste Management Private Limited (start-up at IIT Kanpur).
- The Seed Balls are comprised of indigenous variety of seeds, compost, and clay.
- There is no need for digging pits for planting saplings . These seed walls are to be thrown at aimed places and they will germinate when come into contact with water.
- BEEG is enriched with the right ingredients and seeds to germinate early, and are the best way to utilise Monsoon and plant as many trees as possible without risking lives by social gathering during Covid 19.
NCPOR’s study on Arctic Ice:
- The National Centre of Polar and Ocean Research(NCPOR) has found a dramatic decline in the Arctic sea ice due to global warming.
- The decline of sea ice has led to localized increase in evaporation, air humidity, cloud cover, and rainfall. Arctic sea ice is a sensitive indicator of climate change and has strong retaliatory effects on other components of the climatesystem.
- In its observations, NCPOR has noted that the largest decline in Arctic sea ice in the past 41 years happened in July 2019. In the last 40 years (1979-2018), the sea ice has been declining at a rate of ‘-4.7%’ per decade, while its rate was found to be ‘-13%’ in July 2019. If this trend continues, there would be no ice left in the Arctic sea by 2050, which would be dangerous for humanity and the entire environment.
- With the help of satellite data collected from 1979 to 2019, NCPOR has tried to understand the rate of surface warming and the changes in global atmospheric circulation.
- The study has also pointed out that the decrease of the Arctic sea ice area and the increase in the duration of summer and autumn seasons have affected the local weather and climate over the Arctic Ocean and its marginal seas.
- Being a sensitive indicator of climate change, the loss of ice cover in the Arctic sea has had strong feedback effects on other components of the climate system such as prevention or reduction of heat and momentum, water vapour, and other material exchange between the atmosphere and the sea.
- The worrying element to note is that the volume of ice formation during winters is unable to keep pace with the volume of ice loss duringsummers.
- In the background of the global warming scenario, the study reveals that global ocean-atmospheric warming has enhanced the Arctic sea ice loss. The study demonstrated the application of satellite observations and model reanalysis data for the determination and validation; the 2019 sea- ice extent tied to the second lowest sea ice minimum record.
- Although there are no extreme weather events recorded this year, an accelerated decline in sea-ice extent and sea-ice volume in summer 2019 was dominant, and also the northern hemisphere has experienced record high-temperature rise especially during the spring and summer months.
