Jyeshtha Ashtami

Prime Minister Narendra Modi has extended wishes to the Kashmiri Pandit community on the occasion of Jyeshtha Ashtami.

What is Jyeshtha Ashtami?

  • Jyeshtha or Jyēṣṭha is a month of the Hindu calendar. In India’s national civil calendar, Jyestha is the third month of the year.
  • Jyeshtha Ashtami is an auspicious day which is the eighth day of the bright half of Jyeshtha (May–June) month.
  • Every year, the date varies depending upon the Hindu calendar.
  • According to belief, the Goddess changes the colour of the spring’s waters. 

How is it celebrated?

  • Devotees flock the Mata Kheer Bhawani Temple or Tulmula Mandir in Kashmir in huge numbers.
  • On this auspicious day, a grand feast and fest is held every year at Mata Kheer Bhawani Temple in Kashmir (especially by Kashmiri Pandit community), also known as Tulmula. It is celebrated with full gusto and vigour, as it marks the pradurbhava of the Goddess Ragnya (Kheer Bhavani or Ragnya Bhavani Mata).
  • There are separate shran or snan kunds for ladies and gents, wherein people take a bath or sprinkle the water over their face, hands and feet before paying homage to the residing Ragnya Bhawani Mata. It is considered to be auspicious, and many believe that by doing so the goddess takes away all their worries.
  • Ritually no specific procedure is prescribed for the Puja at Kheer Bhavani. The Bhringish Samhita simply says that the Devi, whose mantra is of fifteen syllables, accepts offerings of milk, sugar candy and ghee only.

Interestingly, another festival is held at the shrine on Asharha Ashtami with equal devotional fervour. It is believed that the sacred spring of the shrine miraculously changes its colour having been discovered on the Saptami of that month.

National AI Portal

Union Ministry of Electronics and IT has launched India’s national Artificial Intelligence Portal called www.ai.gov.in

About the portal –

  • This portal has been jointly developed by the Ministry of Electronics and IT and IT Industry. National e-Governance Division of Ministry of Electronics and IT and NASSCOM from the IT industry will jointly run this portal.
  • This portal shall work as a one stop digital platform for AI related developments in India, sharing of resources such as articles, startups, investment funds in AI, resources, companies and educational institutions related to AI in India.
  • The portal will also share documents, case studies, research reports etc. It has section about learning and new job roles related to AI.

AI for Youth Programme –

  • The National Programme is open to students of classes 8 – 12 from Central and State government-run schools (including KVS, NVS, JNV) from across the country – all 28 States and 8 Union Territories and aims to bring about a change in the thought process and create a bridge for the digital divide.
  • The Program will be implemented in a phase-wise manner and in its first phase, each of the State Education Department will nominate 10 teachers as per the eligibility criteria. Teachers may also self nominate themselves by fulfilling the eligibility criteria.
  • These teachers will be provided orientation sessions aimed to help them understand the premise and identify 25-50 potential students for the Program.
  • The identified students will attend online training sessions on AI and understand how to identify social impact ideas/projects that may be created using AI and submit their ideas through a 60 seconds video explaining a proposed AI enabled solution.

Hub and Spoke Model

To scale up testing and enhance the reach across the country/City/Regional clusters have been established in a Hub and Spoke Model to scale-up testing of COVID-19 samples in government institutions across the country.

What is ‘Hub and Spoke Model’?

The hub and spoke model refers to a distribution method in which a centralised “hub” exists. Everything either originates in the hub or is sent to the hub for distribution to consumers. From the hub, goods travel outward to smaller locations owned by the company, called spokes, for further processing and distribution.

Benefits of ‘Hub and Spoke Model’ –

  • There are many benefits of the hub and spoke model, and it’s perhaps easiest to understand these by comparing the hub and spoke model to the model it was intended to replace: the point-to-point model. The exact opposite of the hub and spoke model, the point-to-point model has goods and services go directly from Point A to Point B without going to a centralised distribution hub.
  • In the point-to-point model, transportation costs can actually be higher than in a hub and spoke model. This happens because more routes are created in a point-to-point model, whereas products can be grouped and efficiently shipped following set routes in a hub and spoke model.
  • A hub and spoke model also makes it possible for transport drivers to travel shorter distances and stay in a more centralised area. That’s because drivers can switch at the hub. In a point-to-point system, there’s no company space for drivers to easily meet and switch.

Example of ‘Hub and Spoke Model’ –

Social media management tools act as centralised hubs where you can draft a single post and then schedule it for publication on sites like Facebook, LinkedIn, Twitter, Instagram, etc. In contrast, you would be using a point-to-point method if you logged into each social media site separately to draft and schedule the same post.

Rozgar Setu

Madhya Pradesh Chief Minister has announced the launch of the ‘Rozgar Setu’ scheme, saying it would help secure employment for skilled workers who have returned.

What is ‘Rozgar Setu’?

  • Madhya Pradesh has become the first state to devise such a work plan.
  • The state plans to survey skilled workers who were employed at industries elsewhere, but have now returned.
  • The attempt is to provide work to the maximum number of returned skilled workers.
  • After such workers requiring employment are identified, the government will contact factory, workshop owners and contractors overseeing infrastructure projects such as road and bridge construction.
  • Rozgar Setu will be a platform to connect them with those needing these skilled workers. The State government will act as a [bridge] between workers and employers so that both are benefited.
  • This would fulfil the manpower requirement of industries as well as provide employment to workers during the COVID-19 pandemic.

D10 Club

Britain has said recently that is was pushing the US to form a club of 10 nations that could develop its own 5G technology and reduce dependence on Huawei.

About the D10 Club –

  • A so-called “D10″ club of democratic partners, including G7 countries – UK, US, Italy, Germany, France, Japan and Canada – plus Australia, South Korea and India will aim to create alternative suppliers of 5G equipment and other technologies to avoid relying on China.
  • It proposes that one of the options involves channelling investment into existing telecommunication within the 10 member countries.


Britain has labelled Huawei a “high-risk” vendor and therefore its involvement in the UK’s 5G upgrade comes with a 35% market cap, including a ban on its participation in the sensitive “core” of the network.

National Numbering Plan

The Telecom Regulatory Authority of India has recommended that a new National Numbering Plan be issued at the earliest so that a uniquely identifiable number can be provided to every subscriber in India.

Proposal –

Some of the options that TRAI has recommended include switching to a 11-digit mobile number, reallocation of mobile numbering resources surrendered by operators who have shut shop and prefixing zero for all mobile calls made from fixed line.

Need –

  • The regulator said adequate availability of numbering resources is threatened because of an increase in the range of services and massive growth in the number of connections, especially in the mobile segment.
  • The ongoing plan implemented in 2003, was developed keeping in mind the projections till the year 2033. The total number of telephone subscribers in India stands at 1,177.02 million with a tele-density of 87.45% at the end of January 2020.
  • As a result, we find ourselves in a situation where we need to review the utilisation of the numbering resources and make some policy decisions to ensure that adequate resources are available for sustainable growth of the telecommunication services.

About TRAI –

  • It is the independent regulator of the telecommunications business in India.
  • It was established in 1997 by an Act of Parliament to regulate telecom services and tariffs in India.
  • In January 2000, TRAI was amended to establish the Telecom Disputes Settlement Appellate Tribunal (TDSAT) to take over the adjudicatory functions of the TRAI.
  • The TDSAT was set up to resolve any dispute between a licensor and a licensee, between two or more service providers, between a service provider and a group of consumers. In addition, any direction, TRAI orders or decisions can be challenged by appealing to TDSAT.

World Health Organisation

US President Donald Trump has announced that he is terminating the country’s relationship with the World Health Organisation. He has accused the WHO of failing to hold Beijing to account over the coronavirus pandemic.

Details –

  • President Trump announced last month that he was going to halt US funding for the WHO unless it undertook “substantive improvements” within 30 days.
  • The WHO’s Director-General, Tedros Adhanom Ghebreyesus, had promised a review of its response to the pandemic and defended its independence.

Why is it significant?

The US is the global health agency’s largest single contributor, providing more than $400m (£324m; €360m) in 2019, around 15% of its total budget.

About World Health Organisation –

  • Founded in 1948 and based in Geneva, Switzerland, it is the UN agency responsible for global public health.
  • Has 194 member states, and aims to “promote health, keep the world safe and serve the vulnerable.
  • Involved in vaccination campaigns, health emergencies and supporting countries in primary care.
  • Funded by a combination of members’ fees based on wealth and population and voluntary contributions.

Funding for WHO –

World Health Organisation is funded through –

Assessed Contributions –

  • These are the dues countries pay in order to be a member of the Organization.
  • The amount each Member State must pay is calculated relative to the country’s wealth and population.
  • These contributions have declined, and now account for less than one-fourth of its funding.

Voluntary Contributions –

  • These come from Member States (in addition to their assessed contribution) or from other partners (organisations & individuals) 
  • They can range from flexible to highly earmarked.
  • Top funders include Bill and Melinda Gates (USD 367.7 million), GAVI Vaccine Alliance, World Bank, Rotary International and the European Commission.

Monoclonal Antibody

A team of researchers from Netherlands went back to look at the frozen antibodies that recognised the 2002 Sever Acute Respiratory Syndrome (SARS-CoV), which they had stored in the early 2000s during the outbreak. Surprisingly, one of the antibodies was found to recognise the infection due to the novel coronavirus, SARS-CoV-2. The study showed that it can help block infection in cultured human cells.

What has been found?

  • The researchers have explained that the antibody binds to a domain that is conserved in both SARS-CoV and SARS-CoV-2, explaining its ability to neutralise both viruses.
  • This antibody can help develop antigen detection tests and serological assays.
  • This antibody — either alone or in combination — offers the potential to prevent and/or treat COVID-19, and possibly also other future emerging diseases in humans caused by viruses from the Sarbecovirus subgenus.

What they intend to do?

The team is set out to make antibodies against SARS, MERS and HCoV-OC43 [another coronavirus] with the aim to get antibodies that would recognise all three coronaviruses. Parts of the proteins of these viruses are highly conserved (which means they are very similar) and the team hopes to get antibodies that recognised these conserved parts.

How will it work?

The fused B-cells called hybridomas are grown individually and tested whether they make an antibody that would recognise the target. Because they come from single B-cells hybridomas, they make only one specific antibody which is called a monoclonal antibody. When a monoclonal-like antibody is given to patients it does its work immediately, that is, much faster that the body could make its own antibodies.

What is a monoclonal antibody?

A type of protein made in the laboratory that can bind to substances in the body, including cancer cells. There are many kinds of monoclonal antibodies. A monoclonal antibody is made so that it binds to only one substance. Monoclonal antibodies are being used to treat some types of cancer. They can be used alone or to carry drugs, toxins, or radioactive substances directly to cancer cells.
