Back2Basics: Artificial intelligence (AI)
- Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions.
- The term may also be applied to any machine that exhibits traits associated with a human mind such as learning and problem-solving.
- The ideal characteristic of artificial intelligence is its ability to rationalize and take actions that have the best chance of achieving a specific goal.
- A subset of artificial intelligence is machine learning, which refers to the concept that computer programs can automatically learn from and adapt to new data without being assisted by humans.
- Deep learning techniques enable this automatic learning through the absorption of huge amounts of unstructured data such as text, images, or video.

Prelims level: Mullaperiyar Dam
Mains level: Interstate river water disputes in India
The Supreme Court has warned the Tamil Nadu Chief Secretary against the failure to give information on the rule curve for Mullaperiyar dam.
Do you know?
The Mullaperiyar dam is located in Kerala on the river Periyar but is operated and maintained by the neighbouring state of Tamil Nadu.
What is the Rule Curve?
- A rule curve or rule level specifies the storage or empty space to be maintained in a reservoir during different times of the year.
- Here the implicit assumption is that a reservoir can best satisfy its purposes if the storage levels specified by the rule curve are maintained in the reservoir at different times.
- It decides the fluctuating storage levels in a reservoir.
- The gate opening schedule of a dam is based on the rule curve.
- It is part of the “core safety” mechanism in a dam.
Why such a move?
- During the high-voltage hearing, the Tamil Nadu government blamed Kerala for delaying the finalization of the rule curve for the 123-year-old dam.
- Kerala government has accused Tamil Nadu of adopting an “obsolete” gate operation schedule dating back to 1939.
About Mullaperiyar Dam
- Mullaperiyar Dam is a masonry gravity dam on the Periyar River in the Indian state of Kerala.
- It is located on the Cardamom Hills of the Western Ghats in Thekkady, Idukki District of Kerala.
- It was constructed between 1887 and 1895 by John Pennycuick and also reached an agreement to divert water eastwards to the Madras Presidency area (present-day Tamil Nadu).
- It has a height of 53.6 m from the foundation, and a length of 365.7 m.
- The Periyar National Park in Thekkady is located around the dam’s reservoir.
- The dam is built at the confluence of Mullayar and Periyar rivers.

Project RE-HAB
- Project RE-HAB stands for Reducing Elephant-Human Attacks using Bees. It is an initiative of the Khadi and Village Industries Commission (KVIC).
- It intends to create “bee fences” to thwart elephant attacks in human habitations using honeybees.
- Bee boxes have been placed on the ground as well as hung from the trees.
- The boxes are connected with a string so that when elephants attempt to pass through, a tug causes the bees to swarm the elephant herds and dissuade them from progressing further.
- This idea stems from the elephants’ proven fear of the bees.
Areas covered by the project
- The pilot project was launched at four locations around Chelur village in the Kodagu district of Karnataka.
- These spots are located on the periphery of Nagarahole National Park and Tiger Reserve, known conflict zones.
Benefits offered
- The biggest advantage of Project RE-HAB is that it dissuades elephants without causing any harm to them.
- It is extremely cost-effective as compared to various other measures such as digging trenches or erecting fences.

Prelims level: Rigvedic rivers
Mains level: Not Much
The Centre has reconstituted an advisory committee to chalk out a plan for studying the mythical Sarasvati River for the next two years after the earlier panel’s term ended in 2019.
Do you know?
Rigveda describes India as a land of Sapta Sindhavah.
There is a verse in Nadistuti sukta of Rigveda , hymn of praise of rivers which mentions the following 10 rivers: Ganga, Yamuna, Sarasvati, Sutudri, Parusni, Asikni, Marudvrdha , Vitasta , Arjikiya , Susoma.
The Shutudri was Sutlej, Parushni was Ravi, Asikni was Chenab and Vitasta was Jhelum.
Sarasvati River
- The Sarasvati River is an extinct river mentioned in the Rig Veda and later Vedic and post-Vedic texts.
- As a physical river, it is described as a small river ending in “a terminal lake (Samudra).
- As the goddess Sarasvati, the main referent for the term “Sarasvati” which developed into an independent identity in post-Vedic times, she is described as a powerful river and mighty flood.
- The Sarasvati is also considered by Hindus to exist in a metaphysical form, in which it formed a confluence with the sacred rivers Ganges and Yamuna, at the Triveni Sangam.
Vedic reference of the river
- Rigvedic and later Vedic texts have been used to propose identification with present-day rivers, or ancient riverbeds.
- The Nadistuti hymn in the Rigveda (10.75) mentions the Sarasvati between the Yamuna in the east and the Sutlej in the west.
- Later Vedic texts like the Tandya and Jaiminiya Brahmanas, as well as the Mahabharata, mention that the Sarasvati dried up in a desert.
What led to its extinction?
- Since the late 19th-century, scholars have proposed to identify the Rig Vedic Saraswati river with the Ghaggar-Hakra river system.
- This flows through northwestern India and eastern Pakistan, between the Yamuna and the Sutlej.
- Recent geophysical research suggests that the Ghaggar-Hakra system was glacier-fed until 8,000 years ago, and then became a system of monsoon-fed rivers.
- ISRO has observed that major Indus Valley Civilization sites at Kalibangan (Rajasthan), Banawali and Rakhigarhi (Haryana), Dholavira and Lothal (Gujarat) lay along this course.
- The Indus Valley Civilisation may have declined as a result of climatic change when the monsoons that fed the rivers diminished at around the time civilisation diminished some 4,000 years ago.

Prelims level: AT1 Bonds
Mains level: Not Much
The decision of the Securities and Exchange Board of India (SEBI) to slap restrictions on mutual fund (MF) investments in additional tier-1 (AT1) bonds has raised a storm in the MF and banking sectors.
What are AT1 Bonds?
- AT1 Bonds stand for additional tier-1 bonds. These are unsecured bonds that have perpetual tenure. In other words, the bonds have no maturity date.
- They have a call option, which can be used by the banks to buy these bonds back from investors.
- These bonds are typically used by banks to bolster their core or tier-1 capital.
- AT1 bonds are subordinate to all other debt and only senior to common equity.
- Mutual funds (MFs) are among the largest investors in perpetual debt instruments and hold over Rs 35,000 crore of the outstanding additional tier-I bond issuances of Rs 90,000 crore.
What action has been taken by the Sebi recently and why?
- In a recent circular, the Sebi told mutual funds to value these perpetual bonds as a 100-year instrument.
- This essentially means MFs have to make the assumption that these bonds would be redeemed in 100 years.
- The regulator also asked MFs to limit the ownership of the bonds to 10 per cent of the assets of a scheme.
- According to the Sebi, these instruments could be riskier than other debt instruments.
Try this PYQ:
Consider the following statements:
- The Reserve Bank of India manages and services the Government of India Securities but not any State Government Securities.
- Treasury bills are issued by the Government of India and there are no treasury bills issued by the State Governments.
- Treasury bills offer are issued at a discount from the par value.
Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 3 Only
(c) 2 and 3 only
(d) 1, 2 and 3
How MFs will be affected?
- Typically, MFs have treated the date of the call option on AT1 bonds as the maturity date.
- Now, if these bonds are treated as 100-year bonds, it raises the risk in these bonds as they become ultra long-term.
- This could also lead to volatility in the prices of these bonds as the risk increases the yields on these bonds rises.
- Bond yields and bond prices move in opposite directions and therefore, the higher yield will drive down the price of the bond, which in turn will lead to a decrease in the net asset value of MF schemes holding these bonds.
- Moreover, these bonds are not liquid and it will be difficult for MFs to sell these to meet redemption pressure.
What’s the impact on banks?
- AT1 bonds have emerged as the capital instrument of choice for state banks as they strive to shore up capital ratios.
- If there are restrictions on investments by mutual funds in such bonds, banks will find it tough to raise capital at a time when they need funds in the wake of the soaring bad assets.
- A major chunk of AT1 bonds is bought by mutual funds.
Why has the Finance Ministry asked Sebi to review the decision?
- The FM has sought withdrawal of valuation norms for AT1 bonds as it might lead to mutual funds making losses and exiting from these bonds, affecting capital raising plans of PSU banks.
- The government doesn’t want a disruption in the fund mobilization exercise of banks at a time when two PSU banks are on the privatization block.
- Banks are yet to receive the proposed capital injection in FY21 although they will need more capital to face the asset-quality challenges in the foreseeable future.
- Fitch’s own estimate pegs the sector’s capital requirement between $15 billion-58 billion under various stress scenarios for the next two years, of which state banks account for the bulk.

Prelims level: Martian blueberries
Mains level: Mars mission worldwide and their success
In 2004, NASA’s Mars exploration rover ‘Opportunity’ found several small spheres on the planet, informally named Martian blueberries which find a resemblance to the similar formation in India’s Kutch region.
There have been several missions to the red planet this year. Make a note of all of them.
Martian blueberries
- Opportunity’s mini spectrometers studied mineralogy and noted they were made of iron oxide compounds called haematites.
- This caused excitement, as the presence of haematites suggests that there was water present on Mars.
- The widely accepted formation mechanism of hematite concretion [hard solid mass] is precipitation from aqueous fluids.
- Hematite is known to form in oxidizing environments hence it can be inferred that water must have played a crucial role in the formation of grey hematite on Mars.
What makes them so special?
- Indian researchers have been studying hematite concretions in Kutch called the Jhuran formation.
- These formations are 145 and 201 million years old.
- Detailed geochemistry and spectroscopic investigations of the haematite concretions in this area revealed that they resemble the ones on Mars.
- They have similar morphology – spherical, often doublet and triplet – and similar mineralogy – a mixture of haematite and goethite.
- Hence, several types of research have shown that the Kutch area is a potential Martian analogue locality.

Prelims level: Raman Thermometry
Mains level: Discom issues
Researchers at IIT Madras have demonstrated that by using Raman thermometry on fibre optic cables, they can achieve the monitoring of power transmission cables.
What is Raman Thermometry?
- Raman spectroscopy is well known as an analytical method for identifying chemical compounds and characterizing the chemical bonding and solid-state structure of materials.
- Perhaps less well known is the fact that one can use Raman spectroscopy to determine the temperature of the material being analyzed.
For that, we need to get familiarized with Raman Effect
- India’s first and so far only Nobel laureate in physics, C.V. Raman, won the prize for his discovery of the Raman Effect.
- This consisted of experimental observations on the scattering of light.
- In the Raman Effect, when light is scattered off an object, say a molecule, two bands are observed, with a higher and lower frequency than the original light, called the Stokes and anti-Stokes bands, respectively.
- By studying the relative intensity of the two bands, it is possible to estimate the temperature of the object that scattered the light.
- The anti-Stokes component of Raman scattering is strongly dependent on the temperature that the material is subjected to.
Thus, by measuring the intensity of the anti-Stokes scattered light we can estimate the temperature. This is Raman thermometry.
Try this PYQ:
Q.Which Indian astrophysicist and Nobel laureate predicted rapidly rotating stars emit polarized light?
(a) Subrahmanyan Chandrasekhar
(b) CV Raman
(c) Ramanujan
(d) Amartya Sen
What has IITM achieved?
- The temperature measurement was performed in not just one location, but in a distributed manner using an optical fibre.
- To achieve this, a pulse of light was launched into the optical fibre and the backscattered radiation was observed.
- The time of flight of the backscattered radiation provided an estimate of the distance from which the light is backscattered.
- This can go up to tens of kilometres. This technique is married to Raman thermometry to get the results for actual measurements over tens of kilometres.
What makes this experiment special?
- The distribution Sector considered the weakest link in the entire power sector.
- We are much aware of Transmission and Distribution loss that is incurred to our DISCOMS.
- This IITM technology helps analyze transmission efficiencies in a better way.
- The present method devised by the team is both economical and provides real-time information.

Prelims level: Human eye and the applied genetics
Mains level: NA
Researchers from London have found that eye colour in Asians with different shades of brown is genetically similar to eye colour in Europeans ranging from dark brown to light blue.
Human Eye Colour
- Human eye colour ranges from black, brown to blue, green, and even red.
- Eye colour is primarily determined by melanin abundance within the iris pigment epithelium, which is greater in brown than in blue eyes.
- There are two forms of melanin – eumelanin and pheomelanin – and the ratio of the two within the iris as well as light absorption and scattering by extracellular components are additional factors that give irises their colour.
- Absolute melanin quantity and the eumelanin–pheomelanin ratio is higher in brown irises, while blue or green irises have very little of both pigments and relatively more pheomelanin.

Q.Recently, LASIK (Lasser Assisted In Situ Keratomileusis) procedure is being made popular for vision correction. Which one of the following statements in this context is not correct?
(a) LASIK procedure is used to correct refractive errors of the eye
(b) It is a procedure that permanently changes the shapes of the cornea
(c) It reduces a person’s dependence on glasses or contact lenses
(d) It is a procedure that can be done on the person of any age
What has the research found?
- Previously a dozen genes (mainly HERC2 and OCA2) were found to influence eye colour.
- The researchers have now identified 50 new genes for eye colour.
- Genetic analysis of nearly 0.2 million people across Europe and Asia helped the researchers to identify the new genes.
- The findings collectively explain over 53% of eye colour variation using common single-nucleotide polymorphisms.
Outcome of the research
- Overall, the study outcomes demonstrate that the genetic complexity of human eye colour considerably exceeds previous knowledge and expectations.
- These findings will help improve our understanding of eye diseases such as pigmentary glaucoma and ocular albinism where pigment levels play a role.

(a) 1 and 2 only
(b) 2, 3 and 4 only
(c) 1 and 4 only
(d) 1, 2, 3 and 4
What is Benzene?
- Benzene is a chemical that is a colourless or light yellow liquid at room temperature. It has a sweet odour and is highly flammable.
- It evaporates into the air very quickly. Its vapour is heavier than air and may sink into low-lying areas.
- It dissolves only slightly in water and will float on top of the water.
Its formation and uses
Benzene is formed from both natural processes and human activities.
- Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke.
- Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibres.
- It is also used to make some types of lubricants, rubbers, dyes, detergents, drugs, and pesticides.
Benzene emission
- The major sources of benzene exposure are tobacco smoke, automobile service stations, exhaust from motor vehicles, and industrial emissions.
- Benzene is present in both exhaust and evaporative emissions. Motor vehicles account for approximately 85% of the total benzene emissions.
- However, ingestion and dermal absorption of benzene can also occur through contact with contaminated water.

Q.Which of the following is/are cited by the scientists as evidence/evidence for the continued expansion of the universe?
- Detection of microwaves in space
- Observation of redshirt phenomenon in space
- Movement of asteroids in space
- Occurrence of supernova explosions in space
Codes:
(a) 1 and 2 only
(b) 2 only
(c) 1, 3 and 4
(d) None of the above can be cited as evidence.
2001 FO32
- There is no threat of a collision with our planet now or for centuries to come.
- Scientists know its orbital path around the Sun very accurately since it was discovered 20 years ago and has been tracked ever since.
- It won’t come closer than 2 million km to Earth, but it will present a valuable scientific opportunity for astronomers who can get a good look at a rocky relic that formed at the dawn of our Solar System.
Proximity to Earth
- For comparison, when it is at its closest, the distance of 2 million km is equal to 5¼ times the distance from Earth to the Moon.
- Still, that distance is close in astronomical terms, which is why 2001 FO32 has been designated a “potentially hazardous asteroid”.
- The reason for the asteroid’s unusually speedy close approach is its highly eccentric orbit around the Sun, an orbit that is tilted 39° to Earth’s orbital plane.
- This orbit takes the asteroid closer to the Sun than Mercury, and twice as far from the Sun as Mars.
- Later, the asteroid slows after being flung back out into deep space and swinging back toward the Sun. It completes one orbit every 810 days (about 2¼ years).
Studying the visitor
- This asteroid will provide an opportunity for astronomers to get a more precise understanding of the asteroid’s size and albedo (i.e. how bright, or reflective, its surface is), and a rough idea of its composition.
- When sunlight hits an asteroid’s surface, minerals in the rock absorb some wavelengths while reflecting others.
- By studying the spectrum of light reflecting off the surface, astronomers can measure the chemical “fingerprints” of the minerals on the surface of the asteroid.

The Himachal Pradesh government has decided to start planting Seabuckthorn in the cold desert areas.
What is Seabuckthorn?
- It’s a shrub that produces an orange-yellow coloured edible berry.
- In India, it is found above the tree line in the Himalayan region, generally in dry areas such as the cold deserts of Ladakh and Spiti.
- In Himachal Pradesh, it is locally called Himalayan chharma and grows in the wild in Lahaul and Spiti and parts of Kinnaur.
- According to the Seabuckthorn Association of India, around 15,000 hectares in Himachal, Ladakh, Uttarakhand, Sikkim and Arunachal Pradesh are covered by this plant.
Try this PYQ from CSP 2019:
Q.Recently, there was a growing awareness in our country about the importance of Himalayan nettle (Girardinia diversifolia) because it is found to be a sustainable source of
(a) anti-malarial drug
(b) biodiesel
(c) pulp for paper industry
(d) textile fibre
Benefits of the Seabuckthorn plant
(1) Medicinal benefits
- As a folk medicine, Seabuckthorn has been widely used for treating stomach, heart and skin problems.
- In the last few decades, scientific research worldwide has backed many of its traditional uses.
- Its fruit and leaves are rich in vitamins, carotenoids and omega fatty acids, among other substances, and it can help troops in acclimatizing to high-altitude.
(2) Ecological benefits
- Besides being an important source of fuelwood and fodder, Seabuckthorn is a soil-binding plant that prevents soil-erosion, checks siltation in rivers and helps preserve floral biodiversity.
- In the Lahaul valley, where willow trees are dying in large numbers due to pest attack, this hardy shrub is a good alternative for protecting the local ecology.
(3) Commercial benefits
- Seabuckthorn also has commercial value, as it is used in making juices, jams, nutritional capsules etc.
- But wild Seabuckthorn cannot sustainably supply raw material to the industry, and the plant needs to be cultivated on a large scale as is being done in China.
What is the latest project?
- The Seabuckthorn association wants the forest departments of various Himalayan states/UTs to plant Seabuckthorn on arid and marginal lands using compensatory afforestation or CAMPA funds.
- Recently, the union ministry of environment, forest and climate change asked these states to submit proposals for taking up such plantations.
- This is in the light of reduced water flow from Himalayan glaciers and their impact on ecology.

Prelims level: Revolution of Earth and other planets around the Sun
Mains level: NA
For us, 365 days make up a year because Earth takes as many days to complete one orbit of the Sun. But have you ever wondered how many days make up a year on other planets?
What determines the length of a year?
- The length of a year on any planet depends on where the planet is orbiting.
- Planets that are closer to the Sun than Earth will have fewer days in a year, while those rotating farther away will take many more days to make up a year.
- This is because of two reasons – planets that are closer to the Sun will take a shorter time to orbit it than those farther away, and the closer a planet orbits the Sun, the Sun’s gravity can pull on the planet, making the planet orbit faster.
Why should we care?
- To send a spacecraft to another planet, we need to know where the planet is in orbit.
- This will help us plan and manoeuvre the spacecraft accordingly.
How long each planet takes to orbit the Sun (in Earth days):
- Mercury: 88 days
- Venus: 225 days
- Earth: 365 days
- Mars: 687 days
- Jupiter: 4,333 days
- Saturn: 10,759 days

From UPSC perspective, the following things are important :
Prelims level: Dandi March
Mains level: Civil Disobedience Movement
PM will flag off a commemorative ‘Dandi March’ on March 12 to launch the celebrations of the 75th year of Independence.
Dandi March
- The Dandi March was an act of nonviolent civil disobedience in colonial India led by Mahatma Gandhi.
- The twenty-four day march lasted from 12 March 1930 to 5 April 1930 as a direct action campaign of tax resistance and nonviolent protest against the British salt monopoly.
- Another reason for this march was that the Civil Disobedience Movement needed a strong inauguration that would inspire more people to follow Gandhi’s example.
- Growing numbers joined them along the way.
- When Gandhi broke the British Raj salt laws at 6:30 am on 6 April 1930, it sparked large scale acts of civil disobedience against the salt laws by millions of Indians.

Followed by Dharasana Satyagraha
- After making the salt at Dandi, Gandhi continued southward along the coast, making salt and addressing meetings on the way.
- The INC planned to stage a satyagraha at the Dharasana Salt Works, 40 km south of Dandi.
- However, Gandhi was arrested on the midnight of 4–5 May 1930, just days before the planned action at Dharasana.
- The Dandi March and the ensuing Dharasana Satyagraha drew worldwide attention to the Indian independence movement through extensive newspaper and newsreel coverage.
- The satyagraha against the salt tax continued for almost a year, ending with Gandhi’s release from jail and negotiations with Viceroy Lord Irwin at the Second Round Table Conference.
Its aftermath
- The March to Dandi had a significant influence on American activists Martin Luther King Jr., James Bevel, and others during the Civil Rights Movement for African Americans in the 1960s.
- The march was the most significant organised challenge to British authority since the Non-cooperation movement of 1920–22.
- It directly followed the Purna Swaraj declaration of sovereignty and self-rule by the Indian National Congress on 26 January 1930.
- It gained worldwide attention which gave impetus to the Indian independence movement and started the nationwide Civil Disobedience.

From UPSC perspective, the following things are important :
Prelims level: LSTV, RSTV
Mains level: Parliamentary behavior and decency
Lok Sabha Television (LSTV) and Rajya Sabha Television (RSTV) have been merged into a single ‘Sansad TV’.
Live telecast of parliament
- Lok Sabha TV is the older of the two — it started operating on July 24, 2006.
- The channel’s vision, according to its website, is to reach the “live proceedings of the Parliament House…to every household”.
- This is because awareness of citizens towards the working of Member of Parliament in the Parliament House helps in bringing awareness about various efforts of various stakeholders in the governance process.
- The information empowers the citizens to utilise their democratic rights diligently and be part of the democratic ecosystem.
Do you know?
The Union Budget allocates funds for the running of channels.
Inception of the idea
- LSTV was the brainchild of former Lok Sabha Speaker Somnath Chatterjee.
- People familiar with the circumstances in which the channel was set up, said that then Rajya Sabha Chairman Bhairon Singh Shekhawat was not really convinced with Chatterjee’s proposal.
- It was during his time of Shekhawat’s successor, Hamid Ansari, that the separate channel for the Upper House materialized.
Before the channels
- Before LSTV started functioning as a channel, select parliamentary proceedings had been televised since December 20, 198.
- On April 18, 1994, the entire proceedings of Lok Sabha started to be filmed.
- And in August that year, a Low Power Transmitter (LPT) was set up and made operational in Parliament House to telecast the proceedings live.
- From December 1994, Question Hour in both Houses was telecast live on alternate weeks on Doordarshan.
- It was arranged in such a manner that during the telecast of the Question Hour of one House by Doordarshan, the Question Hour of the other House was broadcast by All India Radio.
- When the DD News channel was launched, Question Hour in both Houses started getting telecast simultaneously on DD channels.
Separate channels
- But it was only after a decade, in December 2004, that a separate dedicated satellite channel was set up for the live telecast of the proceedings of both Houses.
- In 2006, LSTV started airing the proceedings of the Lower House live.
- RSTV was launched in 2011. Apart from telecasting live the proceedings in Rajya Sabha, it also brings analyses of parliamentary affairs and provides a platform for knowledge-based programmes.
