This year, Kerala faced a sudden surge in Amoebic Meningoencephalitis cases, caused by free-living amoebae (FLA) found in freshwater ponds, lakes, and rivers.
Kerala also saw a diverse range of amoebic infections, caused by Naegleria fowleri, Vermamoeba vermiforis, and Acanthamoeba.
What is Primary Amoebic Meningoencephalitis (PAM)?
PAM is caused by the Naegleria fowleri, often referred to as the “brain-eating amoeba“. It destroys brain tissue, causing severe swelling and is fatal in most cases.
An amoeba is a type of cell or unicellular organism with the ability to alter its shape, primarily by extending and retracting pseudopods.
Higher temperatures of up to 115°F (46°C) are conducive to its growth and it can survive for short periods in warm environments.
The amoeba enters the body through the nose, typically during activities like swimming, and travels to the brain, causing severe damage.
According to the US Centers for Disease Control and Prevention (CDC), most people with PAM die within 1 to 18 days after symptoms begin. It usually leads to coma and death after 5 days.
Diagnosis and Treatment:
Currently, there are no established effective treatments for PAM.
Diagnosis involves PCR tests of cerebrospinal fluid, though detection can be challenging due to the rarity of PAM.
Treatment followsCDC guidelines, including miltefosine, Azithromycin, and Amphotericin B, with miltefosine recently procured by the State Health Department from Germany.
Medical interventions typically involve a combination of drugs, including amphotericin B, azithromycin, fluconazole, rifampin, miltefosine, and dexamethasone.

It has been 100 years since the discovery of the Harappan Civilization, announced by John Marshall on September 20, 1924.
Harappa: Remains of a Civilization
The Harappan Civilization, also known as the Indus Valley Civilization, flourished between 2600 BCE and 1900 BCE, with earlier settlements dating back to 3200 BCE.
The origins of this civilisation are traced back to Mehrgarh in Balochistan, which dates to 7000 BCE.
It is considered one of the three earliest civilizations, alongside Egypt and Mesopotamia.
The civilization covered over 1.5 million sq. km, stretching across modern-day India, Pakistan, and Afghanistan.
Remains of the civilization include:
Well-planned cities with a grid layout, intersecting streets, and fortified structures.
Advanced drainage systems with underground sewers and covered drains, showing a strong emphasis on hygiene.
Granaries, warehouses, and dockyards, indicating the presence of structured trade and food storage mechanisms.
The discovery of seals made of steatite, often engraved with animals and an un-deciphered script, suggesting a sophisticated administrative system.
Craftsmanship in pottery, bead-making, terracotta figurines, metal artefacts, and weaving.
Water management systems such as reservoirs, wells, and baths, indicating an advanced understanding of hydraulic engineering.
The Discoverers:
Two ASI archaeologists were credited with the discovery:
Daya Ram Sahni excavated Harappa in 1921-22, discovering seals, pottery, and beads.
Rakhal Das Banerji began excavating Mohenjo-daro in 1922, finding similar items such as seals and copper objects.
John Marshall noticed the similarity between the objects found at Harappa and Mohenjo-daro, despite the sites being 640 km apart.
About the Mohenjo-daro Site:
Mohenjo-daro is one of the largest cities of the Harappan Civilization, located in the Sindh province of Pakistan, discovered in 1922 by Rakhal Das Banerji.
The city represents one of the finest examples of ancient urban planning:
Great Bath: A large, centrally located structure thought to be used for ritual bathing or religious ceremonies. It is considered one of the earliest public water tanks in history.
Granaries: Massive storage facilities near the citadel suggest an organized system of storing food for the community.
Citadel and Lower Town: The city was divided into a raised citadel for the ruling elite and a lower town for common people. Both areas had well-planned streets and residential complexes.
Drainage Systems: Mohenjo-daro featured covered drainage systems with individual toilets connected to the drainage network, showcasing an impressive public sanitation system.
Residential Buildings: Homes were built from uniform mud bricks, with courtyards and bathrooms, and were often multi-storied. The use of standardised brick sizes (ratio 1:2:4) and cubic weights showed their high degree of organisation.
Artefacts found at Mohenjo-daro include:
Seals with animal motifs and the un-deciphered Harappan script, believed to have been used for administrative or trade purposes.
Pottery and tools made of bronze and copper.
Terracotta figurines, jewellery, and toys that reflect a highly developed artistic culture.
Weights and measures based on a uniform standard, indicating the use of a standardized economic system.
The city’s streets were aligned north-south and east-west, cutting at right angles, allowing for efficient transportation, including bullock carts.
Mohenjo-daro is believed to have had trade links with Mesopotamia, as suggested by artefacts with Mesopotamian connections.

Why in the News?
In a rare celestial event, Earth’s gravitational field will witness a small asteroid, 2024 PT5, creating a “mini-moon” for two months.
What is Mini-Moon?
A mini-moon is a small asteroid temporarily captured by Earth’s gravitational field, orbiting the planet for a short period before escaping back into space.
Unlike Earth’s permanent moon, mini-moons only stay for a few monthsto a few years before being ejected from orbit.
Mini-moons are a rare occurrence because most asteroids either pass by Earth or burn up in the atmosphere rather than being captured by Earth’s gravity.
Mini-moons are usually small, often just a few meters in diameter.
For example, 2024 PT5 is only about 33 feet (10 meters) in length.
They are hard to detect and are usually discovered using advanced telescopicsurveys like NASA’s Asteroid Terrestrial-impact Last Alert System (ATLAS).
Significance of Mini-Moons
Mini-moons offer scientists a unique opportunity to study near-Earth objects, enhancing our understanding of asteroids’ behavior and composition.
Mini-moons could contain valuable minerals or water, making them potential targets for future space missions to extract resources.
Studying mini-moons helps scientists learn more about Earth’s gravitational influence and how it interacts with space objects.

Prelims level: Telescopes
Why in the News?
Modern telescopes, both on Earth and in space, expand our understanding of the universe by gathering and focusing light from distant celestial bodies, revealing cosmic secrets.
ModernTelescopes: Everything you need to know
Primary Functions and Features
Purpose
• Telescopes serve as windows into space, revealing distant celestial bodies and helping explore the universe.
• Their primary function is to gather more light than the human eye can, making faint objects visible.
Types
1. Reflecting Telescopes:
• Use mirrors to focus light and create images.
• Most common in large observatories due to the use of parabolic mirrors, which prevent light scattering and offer clear images. 2. Refracting Telescopes:
• Use lenses to bend and focus light (Concave and Convex lenses used)
• Limited by lens size, with a maximum of about 1 meter (e.g., Yerkes Observatory). Large lenses may sag, distorting the image.
Primary purpose
• Telescopes are designed to collect more light than the human eye.
• The light-gathering ability is proportional to the size of the aperture (opening).
• Example: A small 70mm telescope collects 118 times more light than the human eye.
Features of Telescopes
Brightness and Magnitude
• Celestial objects’ brightness is measured in apparent magnitude (lower numbers = brighter).
• Examples: Sun (-26.78), Venus (-4.92), Sirius (-1.46), Andromeda Galaxy (+3.44).
• Small telescopes can detect objects with magnitudes up to +11.2, which are 100 times fainter than what the human eye can see.
Resolution and Detail
• The resolution of a telescope determines how much detail it can show.
• A small telescope can resolve details 1.47 arcseconds apart (40 times more detail than the human eye, which resolves details 60 arcseconds apart).
Why are Telescopes set up on Mountains?
Mountaintop benefits
• High-altitude observatories are set up to reduce atmospheric distortion, which affects image quality (e.g., stars twinkling).
• Space telescopes, like Hubble, are entirely above the atmosphere and provide clear, undistorted images.
Adaptive Optics
• Ground-based telescopes use adaptive optics to correct atmospheric distortions.
• Lasers create artificial stars, and the telescope adjusts its mirrors to reduce twinkling.
About the New Segmented Mirrors
Overcoming Mirror Limitations
• Large mirrors (over 8.5 meters) can sag under their own weight.
• Segmented mirrors solve this by using smaller sections to create larger, effective mirrors (e.g., Extremely Large Telescope (ELT) with a 39.3-meter aperture).
Notable Telescopes
• Large Binocular Telescope (LBT): Two 8.4-meter mirrors, combined aperture of 11.9 meters.
• Extremely Large Telescope (ELT): Under construction in Chile, it will have a 39.3-meter aperture.
• Subaru Telescope (Hawaii): Captured objects with a magnitude of +27.7, 100 million times fainter than what the human eye can see.

Prelims level: Cheetah Action Plan (CAP)
Why in the News?
The Cheetah Action Plan (CAP) which aimed to introduce African cheetahs into India’s Open Natural Ecosystems (ONEs), is completing its two years.
About Cheetah:
The cheetah is a fast-running big cat, and there are two types of Cheetahs globally:
African (savannahs, arid mountains, and hilly deserts)
Asiatic (desert and semi-desert areas only in Iran)
Cheetahs live in three main groups: females with cubs, male coalitions, and solitary males. They hunt during the day, preferring dawn and dusk.
The global cheetah population was 6,500 mature individuals (IUCN, 2021).
IUCN Status: Vulnerable (Globally) and Critically Endangered (Asiatic Cheetah)
Cheetah Reintroduction in India:
In India, cheetahs disappeared in the early 1950s due to hunting and the loss of their habitat.
Cheetahs (i.e. Southeast African Cheetah) from Namibia were reintroduced in Kuno National Park(MP) under the Project Cheetah.
This area was deemed a habitat parallel to Maasai Mara (National Park) in Kenya, suitable for cheetahs.
Current Issues:
Despite the initial excitement, all of these cheetahs remain in captivity at Kuno.
Unfortunately, no cheetahs are currently roaming freely in the wild, raising concerns about the success of the reintroduction efforts.
What is Project Cheetah?
Aim: To conserve threatened species and restore ecosystem functions. It is spearheaded by the National Tiger Conservation Authority (NTCA).
The plan involves partnering with other countries to conserve cheetahs, enhancing conservation and eco-tourism in India’s dry forests.
The population should reach Kuno National Park’s capacity in 15 years, needing sustained support.
Sunset Clause: The concept of a sunset clause in the context of Project Cheetah refers to the long-term criteria (at least 30-40 years) for establishing a viable cheetah population in India.

Prelims level: National Jute Board (NJB)
Why in the News?
Jute production is expected to declineby 20% this financial year, as per the National Jute Board.
Jute cultivation in West Bengal and Assam was severely affected by natural calamities, including floods, damaging crops in some areas.
About National Jute Board (NJB)
The NJB was established in 2008 under the National Jute Board Act, 2008 (w.e.f. 2010), and operates under the Ministry of Textiles.
Its primary objective is to promote the development of the jute sector by supporting modernization, productivity enhancement, and domestic as well as international marketing of jute products.
It implements various initiatives, such as Jute-ICARE, aimed at improving jute cultivation practices, and promotes Jute Geotextiles for infrastructure projects.
HQ: Kolkata (West Bengal)
NJB implements the Jute Technology Mission (JTM) aimed at improving the productivity, quality, and diversification of jute products.
JTM 2.0 presently focuses on further enhancing the productivity, quality, and diversification of jute.
About the Jute Industry in India
Jute, often referred to as the ‘golden fibre’, is considered safe for packaging due to its natural, renewable, biodegradable, and eco-friendly properties.
The Jute Industry in India is over 150 years old, with approximately 93 jute mills currently in operation, as per the Indian Jute Mills Association (IJMA).
India’s first jute mill was established in 1854 at Rishira, near Kolkata.
However, after independence, India faced challenges as the jute-growing areas remained in Bangladesh while the jute factories were located in India.
The jute industry is a vital sector in East India, particularly in West Bengal.
It supports about 40 lakh agricultural families, employing 1.4 lakh people in the tertiary sector and 2.6 lakh in manufacturing.
India is the largest producer of jute, followed by Bangladesh and China. However, Bangladesh leads in global jute trade, accounting for 75% of exports, while India accounts for 7%.
Jute Cultivation in India
Jute cultivation is mainly concentrated in 3 Indian states: West Bengal, Assam, and Bihar which together produce 99% of the country’s jute.
Conditions Required:
Temperature: 25-35°C
Rainfall: 150-250 cm
Soil Type: Well-drained alluvial soil
This is due to the rich alluvial soil in the Ganga-Brahmaputra delta.
Jute is versatile and used to produce gunny bags, mats, ropes, yarn, carpets, and various artefacts.
Jute seeds are planted between April and May and harvested between July and August.
The leaves can be sold in vegetable markets for nearly two months of the four-month jute crop cycle.
The tall, hardy grass shoots up to 2.5 metres and each part of it has several uses.
The outer layer of the stem produces the fibre that goes into making jute products.
The government fixes the Minimum Support Price (MSP) for raw jute procurement from farmers.
