3. What are Advanced Glycation End Products (AGEs)?
About Advanced Glycation End Products (AGEs):
- AGEs (also known as glycotoxins) are harmful molecules formed by the glycation and oxidation of lipids and proteins.
- Glycation is the process of combining other molecules with sugars.
- Oxidation is the process of combining other molecules with oxygen.
- AGEs are formed in your body by metabolism, but the major source of AGEs is food.
- They are formed in food by grilling, toasting, roasting, broiling, frying, and other high-temperature cooking.
- Tobacco use is yet another source of AGEs.
- AGE production in the body increases with age.
- Why are AGEs harmful?
- AGEs are present in the body at all times. At low levels, they don't cause significant injury.
- However, they cause cell and tissue damage when they reach high concentrations.
- AGEs combine with receptors located on blood vessels and several other organs to cause damage to organ systems.
- These compounds can impact the function of proteins within the cells, alter the behavior of hormones, cytokines, and free radicals, and modify the extracellular matrix between cells.
- AGEs activate inflammatory and other destructive processes in many systems of your body.
- AGEs are involved in the development of various chronic inflammatory diseases such as type II diabetes mellitus, vascular and cardiovascular diseases, osteoporosis, and arthritis.
- Hyperglycemia(high blood levels of glucose) is one condition associated with more AGE production, causing blood vessel damage in people with diabetes.
4. What is Rudder?
About Rudder:
- The rudder is a primary flight control surface which controls rotation about the vertical axis of an aircraft. This movement is referred to as "yaw".
- It is a movable surface that is mounted on the trailing edge of the vertical stabilizer or fin.
- Unlike a boat, the rudder is not used to steer the aircraft; rather, it is used to overcome adverse yaw induced by turning or, in the case of a multi-engine aircraft, by engine failure and also allows the aircraft to be intentionally slipped when required.
- In most aircraft, the rudder is controlled through the flight deck rudder pedals which are linked mechanically to the rudder.
- Deflection of a rudder pedal causes a corresponding rudder deflection in the same direction; that is, pushing the left rudder pedal will result in a rudder deflection to the left.
- This, in turn, causes the rotation about the vertical axis moving the aircraft nose to the left.
- In large or high-speed aircraft, hydraulic actuators are often used to help overcome mechanical and aerodynamic loads on the rudder surface.
- Rudder effectiveness increases with aircraft speed. Thus, at slow speed, large rudder input may be required to achieve the desired results.
- Smaller rudder movement is required at higher speeds, and, in many more sophisticated aircraft, rudder travel is automatically limited when the aircraft is flown above manoeuvring speed to prevent deflection angles that could potentially result in structural damage to the aircraft.

6. Black Carbon
About Black Carbon:
- It is commonly known as soot and is a component of fine particulate air pollution (PM2.5).
- It is formed by the incomplete combustion of wood and fossil fuels, a process which also creates carbon dioxide (CO2), carbon monoxide, and volatile organic compounds.
- Most black carbon emissions in India arise from burning biomass, such as cow dung or straw, in traditional cookstoves.
- It has a warming impact on climate that is 460-1,500 times stronger than CO2.
- Impacts on Environment and Human Health
- It warms the atmosphere because it is very effective at absorbing light.
- It exacerbates the warming of the air and surfaces in regions where it is concentrated, altering weather patterns and ecosystem cycles.
- It lasts only days to weeks in the atmosphere but has significant direct and indirect impacts on the climate, snow and ice, agriculture, and human health.
- It also influences cloud formation and impacts regional circulation and rainfall patterns.
- When deposited on ice and snow, black carbon and co-emitted particles reduce surface albedo (the ability to reflect sunlight) and heat the surface.
- It contributes to global warming and poses severe risks. Studies have found a direct link between exposure to black carbon and a higher risk of heart disease, birth complications, and premature death.

9. What is microRNA?
About microRNA:
- MicroRNAs, or miRNAs, are small, non-coding molecules of RNA.
- They are typically around 19-24 nucleotides long and play an important role in determining how much messenger RNA (mRNA), which carries genetic information, eventually gets translated into protein.
- Role in human body
- These microRNAs act as molecular switches, fine-tuning the expression of genes in different cell types and under varying conditions.
- They regulate the production of proteins by bonding with and subsequently silencing the mRNA at an appropriate juncture. The process is called post-transcriptional gene regulation.
- MicroRNAs help fine-tune various cellular processes like development, growth, and metabolism. Their role is essential in maintaining normal cell function, and disruptions in microRNA activity have been linked to diseases such as cancer.
- Mutations in genes coding for microRNAs have been found in humans, causing conditions such as congenital hearing loss, eye and skeletal disorders.
- Significance of microRNA discovery
- The discovery of microRNAs has provided scientists with new tools to investigate gene regulation and has significantly expanded our understanding of how genetic information is processed and utilized in living organisms.
10. Indian Wild Ass
About Indian Wild Ass:
- It is a sub-species of Asian Wild Ass (Equus hemionus).
- It is locally called khur in the Gujarat region.
- It possesses remarkable characteristics, such as its ability to survive in the extreme conditions of Gujarat’s Wild Ass Sanctuary.
- The primary food source for these animals is the grass that grows on the islands in the desert.
- Appearance: It is characterised by distinctive white markings on the anterior part of the rump and on the posterior part of the shoulder and a stripe down the back that is bordered by white.
- Distribution: The khur was formerly widespread in the arid zone of northwestern India and Pakistan, westwards through much of central Asia. It is now limited to the Little Rann of Kutch in Gujarat.
- Habitat:Desert and grassland ecosystems.
- Conservation Status:
- IUCN: Near threatened.
- CITES: Appendix II
- Wildlife Protection Act (1972): Schedule-I
- Ecological Significance: It is helpful in seed dispersal in the area which helps in promoting vegetation growth and diversity. Besides, it is helpful in habitat creation for other species as it clears pathways by consuming grasses.
- Threats: Increased human presence for salt farming and agriculture and extensive cattle grazing pose a major threat to the delicate ecosystem and its wildlife.
- Irrigation canals that bring water to the southern rim of the Little Rann can also add salinity to the soil.
