FILOBOLETUS MANIPULARIS
Source: Times of India
Why in news?
A rare species of bioluminescent mushrooms, scientifically known as Filoboletus manipularis, has been discovered in the forests of Kasaragod.
- The discovery was made during a micro-fungal survey conducted by the Kasaragod division of the Kerala Forest and Wildlife Department and the Mushrooms of India Community in the Ranipuram forest. Scientists have warned against consuming these mushrooms due to potential toxicity.
About FILOBOLETUS MANIPULARIS
- Filoboletus manipularis is a species of agaric fungus in the family Mycenaceae.
- Filoboletus manipularis is commonly found in Australasia, Malaysia, and the Pacific islands.
- They thrive in tropical, humid environments, typically found in dense forests where there's plenty of decaying organic matter, like fallen trees and leaves. This rich, moist environment provides the nutrients and conditions necessary for their growth and their unique glowing property.
- The glow in Filoboletus manipularis is due to a chemical reaction involving luciferin (a pigment) and luciferase (an enzyme), with oxygen playing a critical role. This reaction produces light, a trait shared with other bioluminescent organisms like fireflies and certain marine creatures.
- In fungi, this glowing mechanism is thought to attract insects, which help disperse the mushroom's spores.

GOVT LOOKS AT INCOME TAX RATE CUT TO BOOST DEMAND
Source: Indian Express
Why in news?
As the Indian economy faces the challenge of declining consumption, policymakers are considering restructuring the current income tax system, especially for lower income brackets.
Key Takeaways
- Government officials suggest prioritizing tax rate reductions for lower-income earners over excessive welfare spending to promote fiscal consolidation.
- Cutting taxes for this group could effectively increase disposable income, leading to higher consumption levels and stimulating economic activities.
- Boosting consumption is crucial for revitalizing demand, which is essential for reigniting private investment, particularly in consumer-driven sectors.
- The potential revenue loss from tax cuts necessitates a comprehensive analysis to evaluate the overall impact. While there might be a loss initially, increased disposable income is expected to drive higher consumption, resulting in enhanced tax revenues.
- The government's focus on fiscal consolidation aims to reduce the fiscal deficit to 5.1% of the GDP by 2024-25 and further below 4.5% by 2025-26.
The Challenge with Marginal Income Tax
- Concerns have been raised regarding the steep increase in marginal income tax rates within the current tax structure.
- Under the new system, the tax rate escalates significantly from the 5% bracket at Rs 3 lakh to 30% at Rs 15 lakh, indicating a substantial jump.
- This steep progression poses challenges as the tax burden grows disproportionately compared to income increments.
Focus on Tax Simplification
- Simplifying the tax structure is deemed more effective than extensive spending on welfare programs, which may be susceptible to leakages.

An Ageing India: The magnitude and the multitude
Source: The Hindu
Why in news?
The phenomenon of ageing stands out as one of the most significant developments of this century, characterized by notable advancements in human longevity alongside historically low reproduction rates.
About the magnitude and multiplication of the aged population
The magnitude of Aging Population:
- The 21st century is witnessing a significant demographic shift marked by a notable increase in human longevity. Improved healthcare and living conditions have contributed to a rise in life expectancy, leading to a larger elderly population. By mid-century, India is projected to have around 319 million elderly people, growing at a rate of approximately 3% annually.
Multiplication of Aging Phenomenon:
- Despite longevity gains, there is a simultaneous decline in fertility rates, leading to an ageing population with a lower proportion of younger generations. This demographic shift poses challenges related to healthcare, social security, and economic sustainability. The elderly population is becoming increasingly feminized, with a higher prevalence of elderly women due to longer life expectancy and higher widowhood rates.
Aged Population as per 2011 Census
- According to the 2011 Census of India, the population of people aged 60 and older in India was 104 million, which is 8.6% of the total population. This is an increase from 5.6% in 1961.
- The census also found that 53 million of the elderly population were female and 51 million were male, with a sex ratio of 1033. 71% of the elderly population lived in rural areas and 29% lived in urban areas. Additionally, 5.18% of the elderly population, or 53,76,619 people, had some disability.
Issues and Challenges
Vulnerabilities of the Elderly:
- Many elderly individuals in India face significant vulnerabilities, including limitations in activities of daily living (ADL), multi-morbidity, poverty, and lack of financial security. A substantial proportion of the elderly report poor health conditions, with a high prevalence of chronic diseases such as diabetes and cancer.
- Mental health issues, particularly depression, are also prevalent among the elderly population.
Social and Economic Insecurities:
- Food insecurity affects a notable percentage of the elderly, with reports of reduced portions or skipped meals due to economic constraints.
Lack of legal protection:
- Awareness and access to welfare measures and legal protections for the elderly are low, with limited knowledge about schemes like IGNOAPS, IGNWPS, and Annapurna.
Abuse and Neglect:
- Elder abuse is a significant concern, especially for elderly women in rural areas who often experience neglect and mistreatment within their families and communities. Social exclusion and limited opportunities for productive engagement exacerbate feelings of insecurity and marginalization among the elderly.
Way Forward
- Enhancing Social Support and Welfare Measures: Strengthening awareness and accessibility of welfare schemes and legal protections for the elderly. Implementing social security measures to ensure financial stability and improve quality of life for ageing populations.
- Healthcare and Mental Well-being: Prioritizing healthcare interventions tailored to the needs of the elderly, including preventive measures against chronic diseases and mental health support. Promoting healthy ageing through lifestyle interventions and healthcare policies that address the unique challenges of an ageing population.
- Empowerment and Social Inclusion: Fostering social inclusion through community engagement and initiatives that empower the elderly to contribute actively to society. Developing innovative institutional frameworks that value the elderly as assets and promote their participation in societal development.

Kanchanjunga express accident - Human error or missing Kavach?
Source: First Post
Why in news?
Nine individuals lost their lives, and over 40 people sustained injuries following a collision involving the Sealdah-bound Kanchanjunga Express from Agartala and a goods train from the rear. This tragic incident took place in the Darjeeling district of West Bengal, approximately 11 km away from the New Jalpaiguri station.
- A combination of a signalling malfunction on the tracks preceding the New Jalpaiguri station and an error by the freight train's driver is believed to have resulted in the fatal crash. Experts stress the significance of implementing the anti-collision system 'Kavach' to mitigate human errors.
Kavach - Train Collision Avoidance System
About
The T/A912 authorization, also known as paper line clearance, provides specific instructions to train operators in case of automatic signalling system failures or defects. It delineates the necessary procedures and speed limitations to ensure safe train operations under such circumstances.
Procedures and speed restrictions
- Signal Procedure: When encountering a red signal, the driver must bring the train to a halt. The train should wait for one minute during the day and two minutes at night when faced with a red signal.
- Proceeding with Caution: After the designated waiting period, the driver can proceed cautiously. Speed should not exceed 15 kmph in good visibility conditions and 10 kmph in poor visibility conditions like during rainfall. The restricted speeds must be maintained until reaching the subsequent stop signal or clear signal indication.
Combination of faulty automatic signalling system and human error - possible reasons behind the accident
- The automatic signalling system between Ranipatra railway station and Chattar Hat junction in West Bengal was non-operational, leading the Rangapani station manager to issue a cautionary note (T/A912) to all drivers passing through that section.
- The driver of the Kanchanjunga Express adhered to the correct protocols during the automatic signalling system malfunction by stopping at red signals for a minute and proceeding at 10 kmph. Conversely, the goods train's driver disregarded these norms, resulting in the collision with the stationary passenger train.
Development of Kavach
- Kavach, formerly known as the Train Collision Avoidance System (TCAS), is an indigenous automatic protection system conceptualized in 2012 and subsequently renamed as 'Kavach' or 'armour'.
- Designed to help Indian Railways achieve Zero Accidents, Kavach is an advanced electronic system developed by the Research Design and Standards Organisation (RDSO) in collaboration with the Indian industry.
Functioning and Features
- The system comprises electronic devices and Radio Frequency Identification devices installed in locomotives, signalling systems, and tracks, facilitating communication using high radio frequencies to manage train brakes and alert drivers.
- Kavach automatically engages the train braking mechanism if the driver fails to adhere to speed restrictions and prevents collisions between locomotives equipped with the system.
- It assists locomotive pilots in avoiding Signal Passing At Danger (SPAD) and over-speeding, crucial factors linked to railway accidents. Furthermore, it supports train operations during adverse weather conditions such as dense fog.
Deployment strategy and Benefits
- Indian Railways planned to implement the Kavach protection system across 2000 km by 2022-23, covering about 34,000 km of the network. This initiative aims to bolster safety for Indian railways and offers the world's most cost-effective automatic train collision protection system, priced at ₹50 lakh per kilometer compared to around ₹2 crore globally.
- Kavach opens doors for exporting this indigenous technology, showcasing its potential for the Railways sector.
