What is Panama Canal?

Panama Canal

About Panama Canal: 

  • It is a man made waterway that connects the Atlantic and Pacific oceans across the Isthmus of Panama.
  • It is owned and administered by Panama, and it is 40 miles long from shoreline to shoreline.
    • It was built by the United states and completed in August 1914,
    • It is one of the two most strategic artificial waterways in the world, the other being the Suez Canal.
    • From its opening in 1914 until 1979, the Panama Canal was controlled solely by the United States, which built it.
    • In 1979, however, control of the canal passed to the Panama Canal Commission, a joint agency of the United States and the Republic of Panama, and complete control passed to Panama at noon on December 31, 1999.
  • It is a sophisticated, highly-engineered system which uses a system of locks and elevators to take ships from one end to the other.
  • This is needed because the two oceans that the Panama Canal connects do not lie at the same elevation, with the Pacific slightly higher than the Atlantic.
  • This difference means that for a ship entering the canal through the Atlantic, it needs to gain elevation during its journey to the Pacific. This is achieved using a lock system which lifts and drops vessels to the required sea level at either end of the canal.
  • Basically, locks are either flooded (to gain elevation) or drained (to lose elevation), and act as water elevators. In total, the system comprises three sets of locks — 12 locks in total — which are serviced using artificial lakes and channels.

Q1: What is an Isthmus?

An isthmus is a narrow strip of land connecting two larger land masses which is bounded by water on two sides. The word has its origins from the Greek word isthmós which means “neck.” News: IE

Mitochondrial DNA Mutations and Age-Related Muscle Loss

Mitochondrial DNA Mutations and Age-Related Muscle Loss

What are Mitochondria?

  • Definition: Mitochondria are membrane-bound organelles present in the cytoplasm of most eukaryotic cells, often called the "powerhouses" of the cell.
  • Maternal inheritance: Mitochondria are inherited exclusively from the mother via the egg cell.

Key functions:

  • Energy production: Generate adenosine triphosphate (ATP), the primary energy carrier required for muscle contraction, protein synthesis, and cell division.
  • Cellular respiration: Facilitates the breakdown of food into energy in the form of ATP.
  • Regulating cell death: Control apoptosis, ensuring the maintenance of healthy tissues.
  • Mitochondrial DNA (mtDNA): Contains its DNA, which is prone to mutations that significantly affect cellular functions.

Key Findings of the Study

  • Deletion mutation’s role: Deletion mutations in mtDNA reduce its size and functionality, gradually eroding mitochondrial efficiency.
    • These mutated mtDNA molecules outcompete healthy ones, leading to a decline in ATP production.
  • Chimeric genes: Deletion mutations create chimeric genes by fusing different mitochondrial genes, forming abnormal sequences.
    • Chimeric genes disrupt mtDNA expression, accelerating mitochondrial dysfunction and muscle degradation.
  • Age-related changes: Older individuals exhibit a two-fold increase in chimeric mitochondrial mRNA, correlating with biological ageing.
    • Mutations also affect brain and muscle tissues, emphasizing their systemic impact on ageing.
  • Biomarkers for biological ageing: mtDNA deletion mutations and chimeric mRNA are key indicators of biological ageing.
    • Understanding these markers could pave the way for therapies to prevent or repair mutations, delaying age-related muscle loss.

FDA Approves Zepbound for Obstructive Sleep Apnoea: A Breakthrough in OSA Treatment

FDA Approves Zepbound for Obstructive Sleep Apnoea: A Breakthrough in OSA Treatment

What’s in today’s article?

  • Why in News?
  • Obstructive Sleep Apnoea (OSA)
  • How Zepbound Works?

Why in News?

The FDA has approved Tirzepatide, marketed as Zepbound, for treating Obstructive Sleep Apnoea (OSA). The drug is recommended alongside a low-calorie diet and increased physical activity for individuals with moderate to severe OSA. 

This approval highlights Tirzepatide's diverse applications beyond managing type-2 diabetes and obesity, as fat accumulation around the neck contributes to throat muscle laxity causing OSA.

It also marks the first drug treatment option for certain patients with obstructive sleep apnoea.

Obstructive Sleep Apnoea (OSA)

  • Types of Sleep Apnoea:
    • Obstructive Sleep Apnoea (OSA): The most common form, caused by physical blockage of the airway.
    • Central Sleep Apnoea: Occurs when the brain fails to send proper signals to muscles controlling breathing.
    • Complex Sleep Apnoea Syndrome: A combination of OSA and central sleep apnoea.
  • About OSA
    • Obstructive Sleep Apnoea (OSA) is a sleep disorder characterized by repeated interruptions in breathing during sleep due to the relaxation of throat muscles. 
    • These interruptions, or apneas, can lead to a choking sensation, causing the person to wake up briefly and disrupt sleep quality. 
    • As a result, individuals with OSA often feel fatigued during the day despite having a full night’s sleep.
  • Link Between Obesity and OSA
    • As per the experts, smaller lungs due to abdominal fat and a floppy tongue are key contributors to OSA, emphasizing obesity as a significant risk factor.
  • Impact of Fat Accumulation
    • Fat around the abdomen reduces lung size, increasing the risk of airway blockage.
    • Neck fat and fat deposits on the back of the tongue can obstruct airways during sleep.
  • Prevalence: Over 50% of OSA patients are obese, and 25% are overweight.
  • Other risk factors
    • Other risk factors include aging, smoking, and a family history of sleep apnoea. 
    • Symptoms of OSA include loud snoring, frequent waking during the night, and excessive daytime sleepiness.
  • Current Treatment for OSA
    • Patients with OSA commonly use a positive airway pressure machine, which delivers pressurized air to keep the airway open during sleep. 
    • Medications may also be prescribed to improve sleep quality. 
    • Weight loss, lifestyle changes, and medications may also be recommended.
    • However, no drug has been available specifically for treating OSA until now.

How Zepbound Works?

  • Zepbound activates the receptors of hormones secreted by the intestine, such as glucagon-like peptide (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which reduces appetite and food intake. 
    • Manufactured by Eli Lilly and Co., Zepbound is approved for individuals who are obese or overweight with related health conditions like type 2 diabetes, high cholesterol, or high blood pressure.
  • Studies suggest that by reducing body weight, Zepbound also improves OSA.
    • Experts noted that excess body fat contributes to diseases like OSA. 
    • Zepbound's weight-loss properties are being linked to benefits in multiple conditions, with additional mechanisms under study.

Q.1. How does Zepbound help in treating Obstructive Sleep Apnoea (OSA)?

Zepbound activates intestinal hormone receptors, reducing appetite and promoting weight loss. This decreases fat accumulation around the neck and abdomen, alleviating airway blockage during sleep, thus improving symptoms of Obstructive Sleep Apnoea (OSA).

Q.2. Why is Zepbound’s approval significant for OSA patients?

Zepbound is the first FDA-approved drug specifically for OSA treatment. It offers an alternative to traditional methods like CPAP machines, particularly benefiting obese individuals by addressing the root cause of OSA through weight loss.

MoSPI Modifying Base Year of Consumer Price Index

MoSPI Modifying Base Year of Consumer Price Index

What’s in today’s article?

  • Why in the News?
  • Consumer Price Index (CPI)
  • Types of CPI
  • How CPI is Calculated?
  • Purpose of CPI
  • Key Issues in the Current CPI
  • Proposed Changes in the New CPI Series
  • Rationale Behind the Proposed Changes
  • Methodological Challenges
  • Broader Implications
  • Conclusion

Why in the News?

  • The Ministry of Statistics and Programme Implementation (MoSPI) is modifying the Consumer Price Index (CPI) base year by updating CPI weights and baskets.
  • MoSPI also plans to gather feedback from users, experts, academicians, government organisations, state governments, financial institutions, and the general public on how to treat free PDS items in the Consumer Price Index compilation.

Consumer Price Index (CPI)

  • The CPI measures the average change in prices of a fixed basket of goods and services that households typically consume.
  • It reflects how the purchasing power of money changes over time due to inflation.
  • Components: CPI includes various categories, such as:
    • Food and Beverages: Items like cereals, pulses, vegetables, milk, meat, and beverages.
    • Housing: Rent or imputed rent for self-occupied houses.
    • Clothing and Footwear: Costs of garments, footwear, and other related items.
    • Fuel and Light: Includes LPG, kerosene, firewood, and electricity.
    • Miscellaneous: Education, healthcare, transport, communication, and recreation expenses.
  • Publishing Authority: The Ministry of Statistics and Programme Implementation (MoSPI) is responsible for compiling and releasing CPI data.

Types of CPI

  • CPI for Industrial Workers (CPI-IW):
    • Tracks price changes for industrial workers.
    • Base Year: 2016
    • Used for wage adjustments in organized labor.
  • CPI for Agricultural Labourers (CPI-AL) and Rural Labourers (CPI-RL):
    • Measures inflation for rural and agricultural laborers.
    • Base Year: 1986-87
  • CPI (Urban), CPI (Rural), and CPI Combined:
    • Measures retail inflation at a national level.
    • Base Year: 2012
  • The CPI Combined is widely used as the official retail inflation rate in India.

How is CPI Calculated?

  • CPI is calculated using the following formula:

CPI = [Cost of the basket ÷ Cost of the basket] x 100

  • Here:
    • The basket of goods and services represents typical household consumption.
    • The base year serves as a reference point for comparison (currently 2012, likely to be revised to 2024).

Purpose of CPI

  • Tracking Inflation: CPI helps monitor the rate at which prices are rising or falling.
  • Policy Formulation: The Reserve Bank of India uses CPI as the primary metric for inflation targeting, maintaining it at 4% ± 2%.
  • Wage and Pension Adjustments: CPI is used to revise salaries and pensions, especially in government sectors.
  • Economic Analysis: It provides insights into consumption trends and economic health.

Key Issues in the Current CPI

  • Exclusion of Free PDS Items:
    • Free goods distributed under the Public Distribution System are currently excluded as they do not involve direct monetary transactions.
    • This aligns with international practices and recommendations, such as those by the International Monetary Fund (IMF), which suggest excluding non-monetary transactions from CPI.
  • Challenges with PDS Inclusion:
    • Redistribution of weights for free items has occasionally caused inflation spikes.
    • Free items complicate inflation calculation as their inclusion may distort the measure of consumer expenditure.

Proposed Changes in the New CPI Series

  • The MoSPI is revising the CPI methodology with 2024 as the new base year. Key changes under consideration include:
  • Inclusion of PDS Items:
    • Reflecting free PDS items at a zero price, with future adjustments as weights change.
    • This could lower headline inflation figures but requires significant adjustments to the CPI calculation process.
  • Redistribution of Weights:
    • Restrict redistribution to the same category (current practice).
    • Broader redistribution across the entire CPI basket for greater accuracy.
  • Stakeholder Consultation:
    • The new CPI series is expected to roll out by the final quarter of FY26, post stakeholder consultations and technical adjustments.
    • MoSPI has invited inputs from experts, academicians, and the public on the proposed treatment of free PDS items, with the deadline set for January 15, 2025.

Rationale Behind the Proposed Changes

  • Economic Representation:
    • The Chief Economic Advisor (CEA) and other experts argue that excluding free PDS items undermines the true representation of market conditions.
    • With increased free food grain distribution during economic crises, including these items may provide a more accurate inflation measure.
  • Alignment with Household Expenditure:
    • The updated CPI will derive weights from the 2022–23 Household Consumption Expenditure Survey (HCES), ensuring the basket reflects current consumption patterns.

Methodological Challenges

  • Compliance with International Norms:
    • Global practices recommend limiting CPI to monetary transactions, complicating the inclusion of free PDS items.
  • Mid-Series Adjustments:
    • Adapting ongoing CPI series to account for changes in PDS pricing—such as shifting from zero to positive prices—presents statistical challenges.
  • Impact on Headline Inflation:
    • Including free items may lower inflation figures, but it risks skewing the index’s purpose of capturing monetary price movements.

Broader Implications

  • Policy Decisions:
    • The revised CPI will serve as a critical input for monetary policy, helping the Reserve Bank of India (RBI) frame more accurate inflation-targeting measures.
  • Global Trade Considerations:
    • As India aims to align its statistical practices with international standards, changes in CPI methodology may affect global investor perceptions.

Conclusion

  • The ongoing deliberations on including free PDS items in CPI aim to enhance the index’s robustness and accuracy.
  • While aligning with international best practices, India’s revised CPI could better capture the dynamics of consumer expenditure and inflation in a rapidly evolving economic landscape.
  • Stakeholder feedback and meticulous planning will be crucial to navigating the statistical and policy complexities of these changes.

Q1. What is the basic difference between Wholesale Price Index and Consumer Price Index?

The main difference between WPI and CPI lies in the scope of goods they measure. WPI tracks price changes at the wholesale level, primarily focusing on goods traded between businesses, while CPI measures price changes at the retail level, focusing on goods and services purchased by consumers.

Q2. What is the purpose of a Monetary Policy?

Central banks use monetary policy to manage economic fluctuations and achieve price stability, which means that inflation is low and stable. Central banks in many advanced economies set explicit inflation targets.

Mammoth

Mammoth

About Mammoth:

  • Mammoths are members of an extinct species belonging to elephantid genus Mammuthus.
  • Time period: They lived from the Pliocene epoch (from around 5 million years ago) into the Holocene at about 4,000 years ago.
  • They existed in Africa, Europe, Asia, and North America. 
  • Features
    • The various species of mammoth were commonly equipped with long, curved tusks.
    • They evolved a suite of adaptations for arctic life, including morphological traits such as small ears and tails to minimize heat loss, a thick layer of subcutaneous fat, long thick fur, and numerous sebaceous glands for insulation.
    • They also had large brown-fat hump-like deposits behind the neck that may have functioned as a heat source and fat reservoir during winter.
  • IUCN Status: Extinct
  • Mammoths are more closely related to living Asian elephants than African elephants. 

Key facts about Permafrost

  • It is any ground—from soil to sediment to rock—that has been frozen continuously for a minimum of two years and as many as hundreds of thousands of years. 
  • It can extend down beneath the earth’s surface from a few feet to more than a mile, covering entire regions, such as the Arctic tundra, or a single, isolated spot, such as a mountaintop of alpine permafrost.
  • They can be found on land and below the ocean floor.
  • It is found in areas where temperatures rarely rise above freezing.

Q1: What is the Holocene Epoch? 

The Holocene Epoch is the current period of geologic time. The Holocene Epoch began 12,000 to 11,500 years ago at the close of the Paleolithic Ice Age and continues through today.

Ocean Anoxic Event 1a (OAE 1a)

Ocean Anoxic Event 1a (OAE 1a)

What is Ocean Anoxic Event 1a (OAE 1a)?

  • Definition: OAE 1a occurred during the Cretaceous Period (145–66 million years ago), marking a time when Earth’s oceans became depleted of oxygen. This led to severe disruptions in marine ecosystems.
  • Causes: Triggered by massive volcanic eruptions, which released large amounts of carbon dioxide (CO₂), resulting in global warming and oxygen depletion in the oceans.
    • These conditions created anoxic marine basins, where oxygen levels were nearly absent.
  • Impacts: The interaction of CO₂ and seawater formed carbonic acid, dissolving marine organisms’ shells and reducing oxygen levels.
    • This resulted in the extinction of several marine species, particularly plankton, and led to the formation of black shales, organic carbon-rich layers preserved in geological records.
  • Anoxic marine basins: Bodies of water, often in deep ocean regions, where oxygen levels are extremely low or absent.
    • Characteristics: Favor the survival of specialized microbes and fungi while inhibiting most aerobic life forms.
    • Carbon Sequestration: Low oxygen levels slow the decomposition of organic matter, aiding in long-term carbon sequestration, which helps reduce atmospheric CO₂ levels.
    • Examples: Black Sea, Cariaco Basin (Caribbean Sea), and Orca Basin (Gulf of Mexico).

Key Highlights of the Recent Study

  • Timing: The event began 119.5 million years ago, confirmed through isotopic analysis of volcanic tuffs from Japan’s Hokkaido Island.
    • OAE 1a lasted approximately 1.1 million years, indicating the extended recovery period for oceans after CO₂-driven warming and anoxia.
  • Volcanic activity: Linked to massive volcanic eruptions, such as the Ontong Java Nui complex, which released significant CO₂ into the atmosphere and oceans.
  • Modern relevance: Highlights parallels between ancient volcanic CO₂ emissions and current human-induced warming.
    • Warns that rapid modern warming could trigger similar disruptions in marine ecosystems and potentially lead to a Holocene extinction event.

Q1) What is the National Institute of Ocean Technology (NIOT)? 

NIOT was established in November 1993 as an autonomous society under the Ministry of Earth Sciences, Government of India. NIOT is managed by a Governing Council and the Director is the head of the Institute.
