Heat Waves in north India
•Several parts of north India are reeling under an intense heatwave with many districts in Rajasthan, Haryana, Uttar Pradesh, Madhya Pradesh posting temperatures over 45 degrees Celsius or five degrees above what is normal.
•Heat Wave is a period of abnormally high temperatures, more than the normal maximum temperature that occurs during the summer season.
[Heat Waves typically occur between March and June, and in some rare cases even extend till July]
Criteria for Heat Waves by IMD
1. Heat Wave need not be considered till the maximum temperature of a station reaches at least 40°C for Plains and at least 30°C for Hilly regions
2. When the actual maximum temperature remains 45°C or more irrespective of normal maximum temperature, heat waves should be declared . etc.
•Ethiopia is building one of the largest dams in the world, the Grand Ethiopian Renaissance Dam (GERD), on the river Nile near the Sudan border
•The hydroelectric dam is being built on the Nile (north-flowing river in Africa), in the lowlands of Ethiopia
◽Do you know?: The Nile is under serious threat of severe pollution, climate change and Egypt’s growing population.
•Egypt is one of the driest countries on earth, with 95% of its people living along the Nile (or its overflowing Delta)
•Recently, Puntius Sanctus, a new freshwater fish, has been found in Velankanni, Tamil Nadu
•It is a silver-hued fish. The species is small in size and grows to a length of 7 cm.
•It is different from other species.
•It has a protractible (extended) mouth, a pair of maxillary barbels (a sensory organ near the snout).
•It bears lateral line scales and pre-dorsal scales.
[Species of Puntius are known from India mainly from the drainages of the Western and Eastern Ghats, as well as the Eastern Himalayas]
•He was a great devotee of Lord Krishna, a poet and a musician.
•He is considered the father of Carnatic Music.
•He formalized the music system which was a blend of various traditions of South India and the musical science as explained in the Vedas.

•It teaches complete self-surrender and unadulterated love towards Lord Krishna, the Supreme.
•Purandara Dasa fought the evils of casteism through his songs. [he wonders what is the use if one does not understand the spirit of humanism whatever caste or status one might be accredited to.]
•According to Purandara Dasa there were no inequalities among men and women
【Department of Archaeology, Heritage and Museums, Karnataka will soon commence field research work at Araga in Malnad (Malenadu) region in Karnataka, to end the speculations regarding the birthplace of Purandara Dasa】
Collaboration/Covid Action Support Group (CoAST India)
•India Observatory has come up with a Geographic Information System (GIS)-enabled dashboard called ‘CoAST India’ to monitor the movements of migrants.
•It draws information from 55 organisations on the ground, mostly in villages.
•The dashboard aims to make such data available to governments and small local civil society groups to be used for planning and providing assistance to migrants.
•The dashboard has been made in collaboration with Foundation for Ecological Security (FES)
【The Foundation for Ecological Security (FES) is a registered non-profit organisation based in Anand, Gujarat.】
ANtarctic Impulsive Transient Antenna (ANITA)
•It is a radio telescope which is used to to detect ultra-high energy cosmic-ray neutrinos from a scientific balloon flying over Antarctica.
•ANITA is the first NASA observatory for neutrinos of any kind.
•It involves an array of radio antennas attached to a helium balloon which flies over the Antarctic ice sheet at 37,000
【In a significant breakthrough, a team of researchers have succeeded in finding `a fountain of high-energy particles erupting from the ice` in Antarctica which according to the researchers could be proof of a parallel universe】
