1 .Guillain-Barré syndrome (GBS) is a rare neurological disorder where the body's immune system mistakenly attacks the peripheral nervous system, the network of nerves outside the brain and spinal cord. This sudden and unexpected condition can cause varying degrees of weakness or tingling sensations, often starting in the legs and spreading upwards. While the exact cause remains unknown, it's believed to be triggered by an infection.

Treatment typically involves plasma exchange or intravenous immunoglobulin to suppress the immune system, along with physical therapy to aid recovery. Most individuals with GBS recover fully, though it may take months or years.

3 .Delhi’s air quality deteriorates to poor category amid rising temperatures: After two days of moderate air quality, Delhi’s air quality has worsened again, falling into the ‘poor’ category. According to the Central Pollution Control Board (CPCB), the Air Quality Index (AQI) at 6 am on Monday was recorded at 242, indicating a significant decline in air quality across the national capital.


While the AQI continues to fluctuate, the weather has also started to show signs of change, as temperatures rise and the cold gradually begins to fade.   


The Air Quality Index (AQI) is a numerical scale that measures the level of air pollution and informs the public about potential health risks. It considers five major air pollutants, including ground-level ozone and particulate matter, and translates their concentrations into a single number. A higher AQI value indicates greater air pollution and increased health concerns, particularly for sensitive groups like children, the elderly, and individuals with respiratory conditions. 


The Air Quality Index (AQI) considers the following five major air pollutants:


  • Ground-level ozone: A harmful gas formed by chemical reactions between air pollutants in the presence of sunlight.   

  • Particle pollution: Tiny particles in the air, also known as particulate matter (PM), which can be inhaled deep into the lungs. This includes PM2.5 (particles smaller than 2.5 micrometers in diameter) and PM10 (particles smaller than 10 micrometers in diameter).   

  • Carbon monoxide: A colorless, odorless gas that can be poisonous at high levels.   

  • Sulfur dioxide: A gas that can cause respiratory problems.   

  • Nitrogen dioxide: A gas that can contribute to respiratory problems and smog

4.Why Trump Wants Greenland: Donald Trump’s interest in Greenland became public in 2019, and it sparked a mix of surprise and debate. His reasoning, though not officially detailed, seemed to stem from strategic and economic considerations. Here’s why he might have wanted to purchase Greenland:


1. Strategic Location

  • Greenland is strategically located in the Arctic, which has growing geopolitical importance due to melting ice caps and increased accessibility for shipping and resource extraction.


  • It could provide the U.S. with a significant military advantage in the Arctic region. The U.S. already has a military base there (Thule Air Base), but owning Greenland would have expanded control over the region.


2. Natural Resources

  • Greenland is rich in natural resources, including rare earth minerals, oil, gas, and other valuable commodities. As global warming makes some of these resources more accessible, owning Greenland could have been seen as an economic opportunity for the U.S.


3. Countering Chinese Influence

  • China has shown interest in investing in Greenland, including plans to build airports and mine rare earth elements. Trump's administration might have viewed acquiring Greenland as a way to limit China’s influence in the Arctic.


4. Economic and Investment Opportunities

  • Trump, as a businessman, may have seen Greenland as an investment opportunity. He even joked about turning it into a real estate project, which aligns with his focus on economic growth and development.


5. Historic Precedent

  • The U.S. has purchased large territories before, like Alaska from Russia in 1867 and Louisiana from France in 1803. This would not have been an entirely unprecedented move.

Denmark and Greenland’s Reaction:

  • Denmark, which oversees Greenland, made it clear the territory was not for sale. Greenlanders themselves dismissed the idea, emphasizing their autonomy and cultural identity.


The United States has made at least three notable attempts to acquire Greenland prior to Donald Trump's proposal in 2019


1867 - Post-Alaska Purchase


  • After the U.S. bought Alaska from Russia in 1867, Secretary of State William H. Seward (a key advocate for territorial expansion) considered acquiring Greenland and Iceland.

  • Seward saw Greenland as strategically valuable, but negotiations never advanced beyond preliminary interest.


2. 1946 - Post-World War II Attempt

  • The most serious attempt occurred in 1946, when President Harry S. Truman offered $100 million in gold to Denmark to purchase Greenland.

  • The U.S. viewed Greenland as a strategic military asset during the early Cold War because of its location in the Arctic and its importance for defending North America from potential Soviet attacks.

  • Denmark rejected the offer, but the U.S. instead signed agreements to establish and expand military bases in Greenland, including the Thule Air Base, which remains operational today.


3. Early Cold War Strategic Interest

  • Even after the failed 1946 purchase attempt, the U.S. maintained a strong strategic interest in Greenland during the Cold War.

  • In the 1950s, the U.S. and Denmark agreed on arrangements that allowed the U.S. to use Greenland for military purposes, effectively giving the U.S. significant influence in the region without owning it outright.
