Mission ISHAN (One Nation, One Airspace)
- News: The Airports Authority of India (AAI) recently issued a call for expressions of interest (EoI) to develop a comprehensive project report for Indian Single Sky Harmonized Air Traffic Management at Nagpur (ISHAN).
- Mission ISHAN:
-
-
- Mission ISHAN represents a concerted effort by the Indian government to integrate the nation’s airspace management system.
-
- Current Airspace Structure:
-
-
- Presently, the Indian airspace is segmented into 4 flight information regions (FIRs) – Delhi, Mumbai, Kolkata, and Chennai, along with a sub-FIR at Guwahati.
- Each of these regions operates autonomously.

Advanced Composite Solar Sail System (ACS3)
- News: NASA recently confirmed that its Advanced Composite Solar Sail System has been successfully deployed.
- Technology Demonstration Mission: Developed by NASA, ACS3 aims to assess the feasibility of utilizing solar sails for propulsion in deep space.
- Compact CubeSat Design: Launched on April 23, 2024, ACS3 is a CubeSat, comparable in size to a toaster oven, featuring a deployable sail of substantial dimensions, akin to a small apartment.
- Innovative Lightweight Construction: Utilizing carbon fiber sail booms instead of conventional metal booms, ACS3 optimizes weight reduction for enhanced performance.
- Solar Sail Propulsion:
- Utilization of Sunlight Pressure: The spacecraft relies on the pressure exerted by sunlight on its reflective sail to generate forward thrust, eliminating the need for conventional propellant.
- Limitless Propulsion Potential: Unlike chemical rockets constrained by finite propellant, solar sails leverage sunlight, offering virtually limitless propulsion capabilities. This characteristic enables solar sails to reach destinations significantly farther than achievable by chemical rockets.
- The Solar Sailing Mechanism:
- Harnessing Photon Momentum: Light comprises photons, which lack mass but possess momentum.
- Reflective Surface Interaction: As sunlight reflects off the shiny surface of the solar sail, it imparts a portion of its momentum, resulting in a gentle push on the sail.
- Continuous Thrust Generation: Although each push is subtle, the cumulative effect over time provides greater thrust compared to traditional chemical rockets, enabling efficient propulsion for extended durations.
Membranous Nephropathy (MN)
- News: Researchers from Kerala reported 15 cases of Membranous Nephropathy (MN) linked to the regular application of fairness creams.
- Autoimmune Kidney Disease:
-
- MN is an autoimmune disorder characterized by nephrotic syndrome, marked by excessive protein excretion in urine (proteinuria), eventually leading to renal failure.
- The body’s immune system targets the glomeruli, small kidney filters responsible for eliminating waste from the blood, impairing their function.
-
- Symptoms: Manifestations of MN include proteinuria (protein in urine), edema (swelling in legs and ankles), fatigue, high blood pressure, and foamy urine.
- Treatment: Treatment typically involves medication and dietary modifications to manage symptoms and slow disease progression.
- Mercury in Fairness Creams:
- Toxic Heavy Metal Usage: Mercury, a highly toxic heavy metal, is incorporated into fairness/anti-aging creams for its ability to inhibit melanin formation, resulting in skin lightening.
- Direct Proportionality: The efficacy of skin lightening is directly correlated with the mercury content in these creams.
- Absorption and Systemic Toxicity: Mercury in creams can permeate the skin via sweat glands, sebaceous glands, and hair follicles, leading to systemic toxicity, notably affecting the kidneys and nervous system.
- Adverse Health Effects: Adverse effects of mercury exposure include skin discoloration, scarring, increased susceptibility to bacterial and fungal infections, as well as psychological manifestations such as anxiety, depression, psychosis, and peripheral neuropathy.
- International Regulatory Framework:
- Minamata Convention on Mercury:
- India, as a signatory to the Minamata Convention on Mercury, is committed to a global treaty aimed at safeguarding human health and the environment from anthropogenic mercury emissions and releases.
- The convention has been in effect since 2017.
- Minamata Convention on Mercury:
Auto-Brewery Syndrome
- News: A Belgian man was recently acquitted of drunk-driving because he had auto-brewery syndrome (ABS).
- Alternative Names and Definition: ABS, also referred to as gut fermentation syndrome or drunkenness disease, is a rare metabolic disorder characterized by the fermentation of carbohydrates in the gut, resulting in alcohol production.
- Alcohol Production in the Body: The condition involves the internal fermentation of carbohydrates within the gastrointestinal tract, leading to the production of alcohol as a metabolic byproduct.
- Intoxication Symptoms without Alcohol Consumption: ABS can induce symptoms of intoxication even in the absence of alcoholic beverage consumption, posing a diagnostic challenge.
- Underlying Causes: It is believed to be associated with an overgrowth of specific yeasts or bacteria within the gut microbiome.
- Symptoms:
-
- Symptoms of ABS mimic alcohol intoxication, including dizziness, headache, and dehydration, despite abstaining from alcoholic drinks.
-
- Increased Risk Factors:
-
- Individuals with diabetes, obesity, and Crohn’s disease are predisposed to ABS; however, it can also affect otherwise healthy individuals.
-
- Dietary Management:
-
- Managing ABS often involves dietary modifications, with medical recommendations suggesting the avoidance of high-carbohydrate and high-sugar foods to mitigate symptoms and alcohol production.

Antihistamines
- News: There has been a rise in the usage of antihistamines to address various health issues.
- Antihistamines: Common Over-the-Counter Drugs: These are readily available drugs used to alleviate short-lived allergic reactions, such as sneezing fits or itching, and are often purchased without a prescription.
- Mechanism of Action:
-
- Antihistamine drugs function by interacting with histamine receptors, which are proteins that bind to histamine compounds in the body.
-
- Composition:
-
- Comprised of ethylamine and imidazole, with the latter forming a ring structure within the compound.
-
- Functions of Histamine:
-
- Histamine exerts its effects through four main types of receptors: H1, H2, H3, and H4.
- H1 Receptors: Predominantly located in blood vessels, neurons, and smooth muscle cells, aiding in the management of minor allergies when blocked by antihistamines.
- H2 Receptors: Found in gastric gland cells, stimulating the release of gastric acid to facilitate digestion.
- H3 Receptors: Present in the central nervous system, regulating the release of neurotransmitters like dopamine and serotonin.
- H4 Receptors: Control the body’s inflammatory response, including allergic reactions.
-
- Current Research Focus: Ongoing research is concentrated on developing specialized drugs that target H3 and H4 receptors to address neurological and immunological disorders effectively.
