 ANSWER: C

ANSWER: A

• NASA scientists have spotted a massive coronal hole on the Sun, which is 20 times larger than Earth, unleashing solar winds towards Earth.
  • Solar winds impact Earth’s magnetic field, satellites and technology.
• Solar winds also lead to generation of aurora at higher latitudes on Earth.

Coronal Holes

• Coronal holes are areas which appear dark in solar corona in extreme ultraviolet and soft x-ray solar images.
• These are regions on the sun’s surface from where fast solar wind gushes out into space.
• In these regions, the magnetic field is open to interplanetary space, sending solar material out in a high-speed stream of solar wind i.e. geomagnetic storm.
• They have lower temperatures and appear much darker than their surroundings as they contain little solar material.
• Coronal holes can last between a few weeks to months.
• The holes are not a unique phenomenon, appearing throughout the sun’s approximately 11-year solar cycle. They can last much longer during solar minimum, a period of time when activity on the Sun is substantially diminished.

 ANSWER: D

 ANSWER: C

• Salt marshes have been playing an outsized role in stabilising the environment.
• But more than 90 per cent of these biologically productive ecosystems may soon succumb to sea level rise by the turn of the century, according to a recent study.

About Salt marshes

• Salt marshes are coastal wetlands that are flooded and drained by salt water brought in by the tides.
• They are found in intertidal zones along coastlines, usually in protected areas such as estuaries or bays.
• They are dominated by grasses and other salt-tolerant plants such as sedges, cordgrass, rushes, and mangroves.
• Salt marshes occur worldwide, particularly in middle to high latitudes.
• Salt marshes protect shorelines from erosion by buffering wave action and trapping sediments.
• They reduce flooding by slowing and absorbing rainwater and protect water quality by filtering runoff, and by metabolizing excess nutrients.

Coastal squeeze

• Marshes all over the globe experience ‘coastal squeeze,’ where their movement is obstructed by sea level rise, anthropogenic activities and geographical factors. For instance, a seawall that protects a home from inundation will prevent a wetland from naturally migrating to higher ground.
• Sea level rise is the most important threat to salt marshes.

 ANSWER: D

 ANSWER: D

• The Indian Space Research Organisation (ISRO) has recently released a Global False Colour Composite (FCC) mosaic of images captured by the Ocean Colour Monitor (OCM) payload on board the EOS-06 satellite.
• The OCM senses the Earth in 13 distinct wavelengths to provide information about global vegetation cover on land and ocean biota for global oceans.

About EOS-06

• The EOS-06 third generation satellite in the Oceansat series was launched by ISRO onboard the PSLV-C54 along with eight Nano-satellites on November 26, 2022.
• EOS-06 provides continued services of Oceansat-2 with enhanced payload capability and carries four payloads OCM, Sea Surface Temperature Monitor, Ku-Band Scatterometer, and ARGOS.
• The EOS-06 is envisaged to observe ocean colour data, sea surface temperature and wind vector data to use in Oceanography, climatic and meteorological applications.
• The satellite also supports value added products such as potential fishing zones using chlorophyll, SST and wind speed and land based geophysical parameters.

 ANSWER: B

• The National Commission for Protection of Child Rights (NCPCR) has written to all States and Union Territories, suggesting that children with Type 1 diabetes (T1D) are provided with proper care and required facilities.

About T1D-

• T1D is a chronic condition in which the pancreas produces little or no insulin, which is a hormone needed to regulate blood sugar levels. This type of diabetes usually occurs in children and young adults, although it can occur at any age.
• According to data from the International Diabetes Federation Atlas 2021, India has the world’s highest number of children and adolescents living with Type I Diabetes Mellitus (TIDM), at over 2.4 lakh, in the southeast Asia region.
• It is an autoimmune disorder, which means that the body’s immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. The exact cause of this condition is not known, but genetic and environmental factors are thought to play a role.
• Type 1 diabetes typically require insulin injections or an insulin pump to manage the blood sugar levels.
• Complications of type 1 diabetes in children can include hypoglycemia (low blood sugar), hyperglycemia (high blood sugar), ketoacidosis (a potentially life-threatening condition that occurs when the body breaks down fat for energy instead of glucose), and long-term complications such as eye, kidney, nerve, and cardiovascular damage.

Other Types of Diabetes

• Type 2 Diabetes:
  • It affects the way the body uses insulin. While the body still makes insulin, unlike in type I, the cells in the body do not respond to it as effectively as they once did.
  • Type 2 diabetes can occur at any age, even during childhood. However, this type of diabetes occurs most often in middle-aged and older people.
  • This is the most common type of diabetes and it has strong links with obesity.
• Gestational Diabetes:
  • This type occurs in women during pregnancy when the body sometimes becomes less sensitive to insulin.

Gestational diabetes does not occur in all women and usually resolves after giving birth.

 ANSWER: A

• Recently, Indian Council of Historical Research has been preparing to release records of people’s ancestors kept by genealogy priests.

About

• Genealogy priests called Panda have been collecting records of families going back 15 to 20 generations, with details like place of origin, names, births, deaths, reason of death, place of residence, grants made to temples, caste, and clan.
  • Genealogy is the study of ancestry.
• Many Hindu families undertake a pilgrimage to religious places like Haridwar or Varanasi upon the death of a family member, where they also visit their family priest to register the death as well as other family developments.
• These records can be a rich source to understand past famines, epidemics, migration, movement of people, as well as social history on how clans and communities were organised.
• The ICHR plans to help make these records available to researchers, scholars, and historians.

 About Indian Council of Historical Research (ICHR)

• The Indian Council of Historical Research (ICHR) is an autonomous organisation under the Ministry of Education, Government of India.
• It was established by the Ministry of Education & Social Welfare, Govt. of India (now, Ministry of Education) in 1972.
• ICHR was registered under the Societies Registration Act.
• The primary aim and objective of the Indian Council of Historical Research are to promote and give directions to historical research and to encourage and foster objective and scientific writing of history.
• It provides fellowships and financial assistance to young teachers in colleges, universities and registered research organisations.
• It publishes a biannual Journal – the Indian Historical Review, and another journal Itihas in Hindi.

 ANSWER: D

• The European Union (EU) has granted the Geographical Indicator (GI) tag to Kangra tea. This will help the tea growers of Kangra export their produce to Europe.
  • The Kangra tea had got the Indian GI tag in 2005.
• According to experts, the production of Kangra tea has fallen to just 8 lakh kg per annum against 17 lakh kg per annum, the highest production recorded in 1998.
• The said production is just .01 per cent of the total 90 million kg tea produced in the country.
• The low yield and lack of initiative among local tea farmers are primary responsible for less production of Kangra tea, according to experts.
• At present, the average yield of tea in Kangra is 230 kg per hectare.
  • However, the average yield of tea is 1,800 kg per hectare at the country level.
• Despite low yield, farmers are carrying out tea plantation in Kangra as the government does not allow the land under tea for any other use.
