A gene called SASS6 (Spindle Assembly Abnormal Protein 6) and its variants have been found to play a key role in a developmental process that causes “Microcephaly”.
What is Microcephaly?
Microcephaly is a condition where a baby’s head is much smaller than normal.
It is associated with a smaller brain, poor motor skills, poor speech, abnormal facial features, and intellectual disabilities.
Developmental Roots:
The condition is believed to start during the peak phase of brain development in the embryo. Cells that are supposed to become neurons fail to divide normally.
Diagnosis:
Microcephaly can be diagnosed before birth using foetal ultrasound and MRI.
Role of SASS6 gene
Since 2014, the SASS6 gene and its variants have been linked to microcephaly.
A recent study in China:(On March 19, 2024)
The study of a consanguine couple revealed microcephaly and fetal growth issues. Confirming the SASS6 gene’s role in microcephaly, findings suggest embryo survival requires at least one functional gene copy.
The University of Cologne Study (February 2024):
Researchers removed all functional SASS6 genes from mouse embryo-derived cells.
Even without the genes, cells could make abnormal but passable centrioles (structures needed for cell division).
When these cells were prompted to become neurons, the centrioles disappeared, preventing the cells from becoming neurons.
Consanguinity and Genetic Risk of Microcephaly
Expert Insight:
Researchers explained that over 70% of congenital microcephaly cases come from consanguineous marriages.
Such marriages increase the risk of inheriting mutated genes from both parents.
Genetic Causes:
Mutations in 30 genes cause microcephaly.
10 of these genes create proteins needed for centrioles, which are crucial for cell division.
Ile62Thr Mutation
2004 Discovery: The SASS6 gene was discovered in the roundworm C. elegans, showing its conserved function across animals.
NASA launched the ” PREFIRE mission”, deploying twin CubeSats to study heat emissions in the Arctic and Antarctic regions, aiming to enhance climate research.
What are CubeSats?
CubeSats are essentially miniature satellites whose basic design is a 10 cm x 10 cm x 10 cm (which makes up for “one unit” or “1U”) cube — just a little bigger than a Rubik’s cube.
weight not more than 1.33 kg.
These satellites were first developed in 1999 by California Polytechnic State University at San Luis Obispo (Cal Poly) and Stanford University as educational tools.
However, owing to their low cost and less mass in comparison to traditional satellites, they began to be put in orbit for technology demonstrations, scientific research, and commercial purposes.
About PREFIRE Mission
Jointly developed by NASA and the University of Wisconsin-Madison.
It aims to investigate and comprehend the intricate dynamics of heat emissions from Earth’s Polar Regions, specifically focusing on the Arctic and Antarctica.
Components:
CubeSats: PREFIRE employs shoebox-sized CubeSats, each measuring around 6U (6 units), equipped with advanced instrumentation to facilitate data collection.
They measure around 90 cm in height and nearly 120 cm in width when the solar panels, which will power the satellite, are deployed.
The two satellites will be placed in a near-polar orbit (a type of low Earth orbit) at an altitude of about 525 kilometres.
Thermal Infrared Spectrometers (TIRS): Each CubeSat is outfitted with a Thermal Infrared Spectrometer, meticulously engineered to measure far-infrared radiation emitted by the Polar Regions.
Mission Objectives:
Investigate heat radiated from Earth’s Polar Regions into space and its impact on climate.
Employ thermal infrared spectrometers to measure far-infrared energy emitted by Earth’s surface and atmosphere.
Improve understanding of the greenhouse effect at the poles and its implications for climate change.
Enhance climate and ice models to predict changes in sea level, weather, snow, and ice cover in a warming world.
Why study heat budget of the Poles?
A large amount of the heat radiated from the Arctic and Antarctica is emitted as far-infrared radiation wavelengths of 3 μm to 1,000 μm within the infrared range of electromagnetic radiation.
However, there is currently no way to measure this type of energy.
As a result, there is a gap in knowledge about the planet’s energy budget.
Significance of PREFIRE
PREFIRE’s observations will enhance predictions of climate and environmental changes, aiding in mitigating the effects of global warming.
Data collected will contribute to updating climate models and improving understanding of Earth’s atmospheric dynamics.

A 4.4 magnitude earthquake struck Italy’s Campi Flegrei super volcano, with Pozzuoli as the epicentre. Felt as far as Naples, it’s the strongest tremor in 40 years
Bradyseism Concerns near Campi Flegrei:
Campi Flegrei is prone to bradyseism, where ground elevation changes due to subsurface pressure.
The area, located 50 kilometres from Mt. Vesuvius, is undergoing a new cycle of bradyseism, according to volcanologists.
Over 500,000 people reside in the red zone adjacent to Campi Flegrei, prompting the Italian Civil Protection Agency to update evacuation plans.
AboutCampi Flegrei Volcano
Campi Flegrei, also known as the Phlegraean Fields, is a large volcanic area located in the western suburbs of Naples, Italy.
It is one of the most active volcanic systems in the world and has been active for at least 50,000 years.
Its Volcanic System:
Location: Campi Flegrei is situated within the Campanian volcanic arc in southern Italy, extending from the city of Naples to the Gulf of Pozzuoli.
Geological Formation: The volcanic system of Campi Flegrei is characterized by a large caldera, which is a collapsed volcanic crater, surrounded by numerous volcanic vents, craters, and lava domes. The caldera has a diameter of about 13 kilometers (8 miles).
Volcanic Activity: Campi Flegrei is considered a supervolcano due to its size and potential for large eruptions. It has experienced numerous periods of volcanic activity throughout its history, including explosive eruptions, lava flows, and phreatic (steam-driven) eruptions.

Mentor comment: More than 160 years ago, railways were introduced in the Indian subcontinent and were first initiated in 1853. The British Governor-General Lord Dalhousie played the most important part in introducing railways in India. Today, India has the 4th largest railway system in the world (after the US, Russia, and China). The railways operate 13,523 passenger trains and 9,146 freight trains daily. As of Feb 2024, 61,813 km length of the Broad-Gauge network has been electrified. With this, Indian Railways is rapidly progressing towards its target of 100% electrification and becoming the largest green railway network in the world. Indian Railways (IR) is rapidly progressing to accomplish its Mission. However, India during recent times due to the increase in population demand, is unable to cope with priority clauses of maintaining safety and standards.
Let’s learn.
–
Why in the News?
A railway pilot (driver) faced disciplinary action for following safety rules and not speeding to minimize delays to passenger trains after his locomotive failed, highlighting an attitude of prioritizing punctuality over safety in the Indian Railways.
According to the Performance Audit on Derailment in Indian Railways, nearly 3/4th of 217 consequential train accidents across the country between 2017-18 and 2020-21 were caused by derailments.
Major challenges of Indian Railway Runways:
Unmanned level crossings (UMLCs): UMLCs are places where railway tracks are crossed without any barriers or signals to regulate traffic.
UMLCs accounted for 16% of all train accidents in India (2018-19). Although Indian Railways have eliminated all the UMLCs on broad gauge routes, there are still many Manned Level Crossings (MLCs) that pose a risk of accidents.
In February 2024, a train consisting of two diesel locomotives (both unmanned), and 53 wagons, with no brakes, rolled out of Kathua station.
Signal Failures: Signaling failures can lead to trains running on the wrong track, colliding with other trains or stationary objects, or overshooting stations.
The recent Visakhapatnam-Rayagada train accident was reportedly caused by non-communication and the lack of audio recording of conversations between station masters and loco pilots.
The media analyzed the accident and highlighted the broader issues with railway safety, such as inadequate signaling and telecommunications infrastructure, and the need for accountability and technological improvements. (In fact, the Right to Information (RTI) Act 2005 denies giving this information)
Human Errors: According to the Final Report of the CRS (Minister for Railways), railway staff are prone to human errors due to fatigue, negligence, corruption, or disregard for safety rules and procedures.
It can result in wrong signaling, miscommunication, distraction, overspeeding, or overlooking defects or hazards that affect their performance and coordination.
What are other troubling questions?
Lack of Professionalism in Railway Accident Investigations: Railway authorities are majorly exposed for unprofessional handling of serious accident investigations. Blaming reckless crew diverts attention from the administration’s role in improper training and ineffective monitoring.
Issues Concerning Loco Pilots: Nearly 10% of vacancies in the loco pilot cadre, are leading to regular breach of duty hour rules. Continuous night shifts, and inadequate rest, point to the need for focused attention on loco pilots’ issues.
What did the CAG Recommended? (Way Forward)
Develop a strong monitoring mechanism to ensure timely implementation of maintenance activities, adopting fully mechanized methods and improved technologies.
Railway administration must follow the guiding principles for the deployment of RRSK (Rashtriya Rail Sanraksha Kosh) funds.
Indian Railways should prepare a Detailed Outcome Framework for each item of safety work.
Ensure strict adherence to scheduled timelines for conducting and finalizing accident inquiries.
In the Terai region of Uttar Pradesh, the farmers are using razor wire and electric fencing to defend their farms against stray cattle.
About the Wildlife Populations in the Biodiverse Terai Areas of Uttar Pradesh
The Terai region in the U.P., encompassing districts like Pilibhit, Lakhimpur Kheri, and Bahraich, is known for its rich biodiversity, thriving sugarcane agriculture, and two tiger reserves.
This area supports endangered species such as tigers, rhinoceros, swamp deer, and the Bengal florican. The landscape blends forests, grasslands, and agriculture, creating a habitat where people and wildlife coexist.
What does the Statistics say?
During the 2022-23 fiscal year, the livestock industry accounted for 30.1% of India’s Agricultural GDP and 4.35% of the national GDP.
India’s farming practices involve a blend of crop farming and livestock rearing. This combined approach offers extra income and job prospects, especially supporting landless workers, small-scale farmers, and women in the workforce.
Constitutional Provision for the Protection of stray cattle:
As per Article 243(W) of the Constitution of India, the local bodies are responsible for cattle pounds and pinjrapole. Therefore, the State may also endow panchayats to establish and run. Cattle Pounds (Kanji Houses)/ Gaushala Shelters (community assets) to keep stray cattle.
Many States have established Gaushalas and Shelter houses for stray cattle and provide for feeding of those animals.
Present Conflicts and Conservation Challenges:
Conflicts between humans and wildlife are common, including tiger attacks and crop damage by herbivores.
Farmers near protected areas sometimes use lethal methods such as razor wire and high-voltage electric fencing along the farm-forest boundaries. The presence of stray cattle, or “chutta jaanwar,” has intensified conflicts and conservation challenges.
Stray cattle disrupt wildlife movement corridors vital for species survival and potentially increase disease transmission risks to wild populations.
The Unvaccinated stray cattle can transmit diseases like bovine tuberculosis and lumpy skin disease to wildlife, with cases reported in various Terai districts.
The degradation of productive grasslands in protected areas further threatens the habitat of imperilled species.
Way Forward:
Providing safe and comprehensive shelters: Construct adequate cow shelters outside protected areas to house stray cattle, preventing them from impacting wildlife habitats and agricultural fields.
Promote and subsidize non-lethal fencing solutions for farmers to protect crops without harming wildlife, such as wildlife-friendly barriers.
Invest in habitat restoration projects in the Terai, focusing on expanding and maintaining productive grasslands within protected areas to support wildlife populations.
Enhanced monitoring and management: Implement comprehensive vaccination and disease monitoring programs for stray cattle to prevent disease transmission to wildlife.
Strengthen enforcement against illegal cattle trade and vigilante activities that disrupt the livestock economy.
Provide economic incentives and support for farmers to adopt alternative livelihoods that do not depend heavily on livestock, reducing the need for cattle rearing.
Community Engagement and Education: Engage with local communities to educate them on the ecological impact of stray cattle and encourage participatory conservation efforts. Foster collaboration between farmers and wildlife authorities to develop sustainable solutions for coexisting with wildlife.

India’s imports from China crossed $101 billion in 2023-24 from about $70 billion in 2018-19, and the country’s share of India’sindustrial goods imports has risen from 21% to 30% over 15 years, according to a report by the Global Trade Research Initiative (GTRI).
The data shows, it’s resulting in a cumulative trade deficit exceeding $387 Billion in the last 5 years, which is an alarming situation for the Indian government.
What is meant by Trade Deficit?
A trade deficit refers to a situation where the country’s imports exceed the receipts from its exports. A trade deficit arises in the course of international trade when the payments for imports exceed the receipts from export trade.
A trade deficit is also referred to as a negative balance of trade.
The concerns arising due to this deficit include pressure on external payments and on the currency value of a country. Countries often alter import and export policies, curbing imports or increasing import duties on certain goods due to this.
They also encourage exports and consumption of indigenous goods.
India’sIndustrial Imports from China:
Electronics and Telecom Sector: During April-January 2023-24, India’s import value for electronics, telecom, and electrical products was $67.8 billion, with China contributing $26.1 billion. (38.4% of the total imports)
Machinery Sector: China contributed 39.6% of India’s imports in this category. This highlights China’s essential role as a supplier of machinery to India.
Chemical and Pharmaceutical Sector: India’s chemical and pharmaceutical imports were $54.1 billion, with $15.8 billion coming from China (29.2% of the total).
MSMEs sector: Products like mobiles and data processing units, are imported by Indian MSMEs. These imports could potentially be produced domestically, highlighting gaps in India’s industrial capabilities.
Current Trade Observations concerning China and other countries:
Rising Trade Deficit with China: India’s exports to China have stagnated at around $16 billion annually (from 2019 to 2024), while imports from China surged from $70.3 billion in 2018-19 to over $101 billion in 2023-24.
Growth Rate of Imports: China’s share in India’s industrial product imports increased from 21% to 30% over the last 15 years. China’s exports to India grew 2.3 times faster than India’s total imports from all other countries.
Diverse Product Imports: Chinese firms are increasingly entering the Indian market, which is expected to accelerate the import of industrial products from China. India’s imports span high to low-technology items, like smartphones, electronics, electric vehicles, and solar energy.
Strategic Concerns: The growing trade deficit and dependence on China have profound strategic implications, affecting both economic and national security dimensions.
Way Forward:
Supply chain diversification: India must focus on diversifying its supply chains and reducing dependency on single-country imports, especially from geopolitical competitors like China.
Boosting R&D: Increase investment in research and development for electronics, semiconductors, and machinery to foster innovation and improve domestic production capabilities.
Incentivizing Production: Provide tax incentives, subsidies, and grants to local manufacturers of electronics, data processing units, and semiconductor devices to encourage production and reduce import dependency.

Despite improvements in menstrual hygiene, female prisoners in India face neglect, highlighting systemic biases and unmet basic needs like sanitary products and proper facilities.
About NFHS Recently Conducted Survey:
The 5th round of the National Family Health Survey (NFHS 2019-2020) revealed that approximately 80% of young women aged 15-24 years are now using safe menstrual hygiene products.
This survey highlights a positive shift in menstrual hygiene management across India, particularly in urban areas and among certain demographics.
About the NCRB Data:
According to the National Crime Records Bureau (NCRB), there are 23,772 women in Indian prisons. Of these, 77% are in the reproductive age group (18-50 years) and are likely to be regular menstruators.
The availability of sanitary napkins has been inconsistent across different prisons, and the quality has often been unsatisfactory.
Many States have not implemented provisions from “the 2016 Model Prison Manual”, such as supplying adequate water and washroom facilities for female prisoners.
Overcrowding and poor socio-economic conditions further exacerbate the struggle of incarcerated women to secure basic necessities during menstruation.
BACK2BASICS: National Crime Records Bureau (NCRB)
NCRB was set up in 1986 to serve as a repository of information on crime and criminals. Its establishment was based on the recommendations of the Tandon Committee, the National Police Commission (1977-1981), and the Ministry of Home Affairs Taskforce (1985).
It is part of the Ministry of Home Affairs (MHA) and is headquartered in New Delhi.
NCRB acts as a “national warehouse” for the fingerprint records of both Indian and foreign criminals. It assists in locating interstate criminals through fingerprint searches.
About the National Menstrual Hygiene Policy:
In 2023, India formulated this policy to recognize menstruation as a natural process requiring meaningful attention. The policy aims to ensure equity in the safe and dignified management of menstrual hygiene.
It prioritises ensuring that all menstruating individuals, regardless of their socioeconomic status and geographical location, have equal opportunities to access and manage their menstruation safely and hygienically.
The Ministry of Home Affairs, which influences menstrual hygiene management in prisons, is overlooked as a critical stakeholder in the policy.
The key challenge of the policy is that it identifies prisoners as a target population with compromised access to menstrual hygiene facilities but lacks a concrete action plan to enhance menstrual hygiene management in prisons.
Other Government Initiatives to Improve Menstrual Health and Hygiene (MHH) in India
Integration of MHH into ASHA’s Role (2005-2010): The government integrated menstrual health and hygiene into the responsibilities of Accredited Social Health Activists (ASHA) as part of the National Rural Health Mission.
Menstrual Hygiene Scheme (MHS) Launched (2010): India initiated the Menstrual Hygiene Scheme (MHS) to distribute sanitary napkins to young girls.
Rashtriya Kishor Swasthya Karyakram Programme (2010): This program, under the Reproductive, Maternal, Newborn, Child and Adolescent Health scheme, increased awareness and access to sanitary pads.
Menstrual Hygiene Management Guidelines Issued (2011-2015): In 2011, the Ministry of Health and Family Welfare issued menstrual hygiene management guidelines. Additional directions were issued by the Ministry of Drinking Water and Sanitation in 2015.
Nirmal Bharat Yatra and Samagra Shiksha Abhiyan (2012): The Nirmal Bharat Yatra, a flagship sanitation program, included MHH as an integral aspect of its agenda. Simultaneously, other similar programs under the Samagra Shiksha Abhiyan began, including initiatives to promote sanitary napkin vending machines and incinerators for safe disposal.
WASH targets for prisons:
Way Forward:
Ensure Basic Standards of Menstrual Hygiene: The Indian government must guarantee that basic standards of menstrual hygiene for women in captivity are met consistently across all prisons.
Implement Model Prison Manual 2016: The government must ensure that all States adhere to the recommendations outlined in the manual, which includes provisions for adequate water and washroom facilities for female prisoners.

The Kerala state government permitted Kerala Forest Development Corporation (KFDC) to plant eucalyptus for financial reasons in 2024-2025. Environmentalists objected, citing forest impact and potential human-animal conflicts.
Reasons for Allowing KFDC to Plant Eucalyptus Trees:
Financial Sustenance: KFDC was permitted to plant eucalyptus trees to support its financial viability.
Existing Plantations: KFDC manages around 7,000 hectares of plantations, including eucalyptus, which contribute to its revenue generation.
Rotation Age: Plantations like eucalyptus have specific rotation ages for harvesting, ensuring a continuous cycle of revenue generation.
Significance of Eucalyptus
Timber and Fuel: Eucalyptus wood is extensively used in Australia as fuel and for building construction, fencing, and other timber applications.
Paper and Pulpwood: The bark of many eucalyptus species is used in papermaking and tanning, while the wood is used for pulpwood production.
Eucalyptus Oil: The leaves of many eucalyptus species contain aromatic oils, which are used for various purposes such as:
Medicinal Uses: Eucalyptus oil is used in expectorants and inhalants to relieve respiratory issues like asthma and bronchitis.
Insect Repellent: The oil is used as a natural insect repellent.
Antimicrobial Activity: Eucalyptus oil has antimicrobial properties, making it effective against bacteria and fungi
Why were environmentalists and social activists against the order?
Ecological Impact: Environmentalists raised concerns about the adverse effects of eucalyptus plantations on natural forests and ecosystems.
Human-Animal Conflicts: The proliferation of invasive species like eucalyptus was linked to increased human-wildlife conflicts, as animals ventured into human habitats in search of food due to habitat depletion.
Contravention of Eco-Restoration Policy: Activists argued that permitting eucalyptus plantations contradicted the state’s eco-restoration policy, which aimed to phase out exotic species and replace them with natural forests by 2024.
Invasive Species Management: The order was seen as undermining efforts to eradicate invasive species and mitigate their damaging effects on natural habitats and ecosystems.
Government Initiatives for Plant Conservation:
The National Bureau of Plant Genetic Resources (NBPGR) in India operates seed banks to conserve crop diversity and wild plant species.
National Afforestation Programme (NAP) has been implemented since 2000 for the afforestation of degraded forest lands. It is being implemented by the MoEFCC.
Conclusion: The controversy over eucalyptus planting in Kerala reflects the balance between financial sustainability and ecological concerns. While eucalyptus offers economic benefits, it also poses ecological risks and challenges to conservation efforts.
