DRDO created Anti-Drone System conveyed in 74th I-Day festivities

Why in News:

As the Prime Minister Modi tended to the nation at the Red Fort, DRDO (Defense Research Development Organization) hostile to ramble framework was conveyed for PM security.


The counter automaton framework can identify miniaturized scale drones as much as 3 kilo meters. It utilizes LASER to cut down objective up to 1-2.5 kilo meters. It can recognize and distinguish drone dangers.

Automatons are Unmanned Aerial Vehicles. They are controlled distantly by aggressors to convey explosives.

The DRDO grew counter automaton frameworks were first sent to give security spread to Brazilian President Jair Bolsonaro when he first showed up in Quite a while.

India has acquired a few guidelines for drone utilization in the nation.

Automated Aircraft System Rules, 2020:

The standards were given by Ministry of Civil Aviation in June 2020. This was on the grounds that, the utilization of automatons have expanded due to COVID-19 lock down. The key guidelines are as per the following.

Automaton Regulation 1.0:

This was given by the Directorate General of Civil Aviation in 2018. As per these standards, an automaton can be worked simply in the wake of looking for authorization through Digital Sky Platform

Computerized Sky Platform:

The stage is an automaton traffic the executives framework that encourages enrollment and permitting of automatons. It works giving moment freedom to administrators for each flight. The whole cycle will be done on the web.

The Drone Regulation 1.0 has apportioned the sky into red zone, green zone and yellow zone. Flying isn’t allowed in red zones. Controlled utilization of air space is allowed in yellow zones and programmed authorization is benefited to fly automatons in green zones.

The GoI is chipping away at Drone Regulations 2.0. It centers around BVLOS (Beyond Visual Line of Sight), Automate the air traffic the executives and conveyance of payloads.

MPEDA opens Quality Control Lab in Porbandar; India misses Sea Food Export Target in 2019-20

Why in News:

The Marine Products Export Development Authority (MPEDA) opened a Quality Control Laboratory in Porbandar. The lab is to test fish processors and exporters.


The lab is to test fish processors and exporters to ensure their items are protected by global administrative prerequisite. It is furnished with gear to dissect anti-microbial deposits and overwhelming metals, for example, lead, cadmium, arsenic and mercury. These deposits and metals are to be tried fish, mackerel and furthermore histamine in fish.


Histamine is a compound delivered by fish because of hypersensitivity and fiery responses. It causes withdrawal of smooth muscle and widening of vessels.

Why in Gujarat?

Gujarat has low occasions of anti-toxin deposits in oceans nourishments. In any case, various cephalopod transfers are dismissed abroad because of the nearness of overwhelming metals, particularly Cadmium.

Creation of Sea Foods:

As indicated by Central Marine Fisheries Institute, Gujarat is underdog to Tamil Nadu in marine fish arrivals. It added to 7.49 lakh tons in 2019.

The significant ocean nourishments being traded from Gujarat are solidified blade fish, solidified shrimp, dried things. They are sent out to European Union, China, South-East Asia, US and Japan. Likewise, Gujarat is the significant exporter of Suirmi fundamentally to Japan.

India Sea Food Exports in 2019-20:

In 2019-20, India Seafood Exports missed their 7 billion USD target. In 2019-20, India transported 1,289,651 tons of fish. This was worth 6.68 billion USD. In 2019, India traded ocean nourishments of worth 6.73 billion USD.

NTPC creates framework for expanded utilization of Fly Ash

Why in News:

The National Thermal Power company created framework at Rihand venture in Uttar Pradesh to move fly debris to solidify plants at less expensive expense.


The framework is being created to help NTPC accomplish its objective of 100% use of fly debris from power plants. This will empower power plants to overhaul the usage of fly debris. In the year 2019-20, around 44.33 million tons of fly debris were used. This is 73.31% of fly debris produced.

Fly Ash:

Fly debris is a coal ignition item.


In 1999, Ministry of Environment, Forest and Climate Change (EFOCC) gave notice in 1999 to guarantee 100% use of fly debris. It was additionally altered in 2003 and 2009. Be that as it may, it was missed by practically 40%. In 2015, GoI fixed December 31, 2017 as overhauled cutoff time to accomplish 100% use. In any case, till date just 55.7% of fly debris is being utilized.

The framework created by NTPC is significant as it will help accomplish 100% use of fly debris.

Fly Ash utilization:

In India, Ultra High Volume Fly debris Concrete is produced for broad use. Fly debris is presently utilized in low to direct quality cement. Additionally, it is utilized in concrete. Fly debris is likewise utilized in blocks supplanting typical earth blocks.

Decisions on fly debris:

In 2016, the fly debris warning gave by the Ministry of EFoCC made it required for the development ventures situated inside 300 km of a warm force plant to utilize fly debris items. Additionally, the red earth blocks situated inside 300 km will change over into fly debris blocks.

As per the decision, the fly debris ought to gauge at least half of the information materials.


The decisions of fly debris were given under Environment Protection Act, 1986. Additionally, as per the Environment Protection Rules, 1986, the Central Government will give notice at whatever point if feels that preclusion of a cycle or activity ought to be forced to ensure the earth.

New COVID-19 strain with 10-times more infection rate detected in Malaysia

Why in News:

Malaysia has recently detected a new COVID-19 strain that is 10 times more infectious. The mutation of the virus is called DG14G.


According to the Malaysian Government, the mutation was found in at least three of the 45 case. Also, it started from a restaurant owner who had returned from India. The Government also reported that he breached his 14 day Home Quarantine.

According to doctors, the new mutated virus is capable of spreading the disease at faster rate.

It is the official name given to the new mutated COVID-19 virus. It was first detected in Europe. However, it is now being seen in different parts of the world and has been found in Malaysia for the first time. The D614G is located within the virus protein that makes up the spikes. These spike proteins are used by the virus to break into the human cells. The mutation changes are found at the 614th position of the amino acids in the spike proteins. It is between D (aspartic acid) and G (Glycine) and hence the name D614G.

Indian researchers have found 73 variants so far

The researchers from Council of Scientific and Industrial Research (CSIR) have so far found 73 new variants of COVID-19 in their three months of research.

What is mutation?

It is the change in structure of gene caused due to insertion deletion or rearrangement of larger sections of genes. This does not mean that mutation should be anthropogenic. Mutation also occurs naturally and mainly when a gene is passed on from one generation to other.

Sometimes, mutation can even lead to a weaker virus.


According to WHO, one-third of COVID-19 samples show mutation. The WHO had earlier reported that the increase in COVID-19 cases in Italy and New York might be predominantly due to D614G.

Mutations in other viruses:

COVID-19 virus is mutating very slowly. Similar mutations were also found in other deadly viruses such as small pox, herpes, and Human Papillomavirus.
