1) India Innovation Index 2022: Karnataka has topped Niti Aayog’s India Innovation Index 2022 among major states, while Chandigarh has topped among city-states and union territories Manipur has topped among northeast and hill states.
- Prepared by NITI Aayog and the Institute for Competitiveness, the India Innovation Index is a comprehensive tool for the evaluation and development of the country’s innovation ecosystem.
- The index is based on seven pillars: human capital, investment, knowledge workers, business environment, safety and legal environment, knowledge output, and knowledge diffusion
2) Kali Bein: The 165-km rivulet starts from Hoshiarpur, runs across four districts and meets the confluence of the rivers Beas and Sutlej in Kapurthala
- Waste water from villages as well as industrial waste used to flow into the rivulet via a drain, turning its waters black, hence the name Kali Bein (black rivulet)
- The Kali Bein is of great significance to Sikh religion and history, because the first Guru, Nanak Dev, is said to have got enlightenment here.
3) Nord Stream Pipeline: Nord Stream consists of two pipelines, which have two lines each.
- The 1,224 km, $11-billion underwater link is the shortest, most economical and environment-friendly route to double Russia’s gas export to Germany.
- The twin pipelines together can transport a combined total of 110 billion cubic metres (bcm) of gas a year to Europe for at least 50 years.
4) Tetrapods: Tetrapods are four-legged concrete structures that are placed along coastlines to prevent coastline erosion and water damage.
- Also known as wave breakers, Tetrapods were first used in France in the late 1940s to protect the shore from the sea.
- They are typically placed together to form an interlocking but porous barrier that dissipates the power of waves and currents.
5) Terzan 2: NASA has released an image of the globular cluster Terzan 2 in the constellation Scorpio captured by the Hubble Space Telescope.
- Globular clusters are the stable, tightly bound clusters of tens of thousands to millions of stars.
- They are found across a variety of galaxies.
- They get their regular, spherical shape from the intense gravitational attraction between the closely packed stars.
