Piezoelectric Effect
Scientists have reported evidence of the piezoelectric effect in liquids, for the first time.
- Piezoelectric effect was found in 2 pure ionic liquids (i.e. liquids made of ions instead of molecules) at room temperature.
- The liquids also displayed the inverse piezoelectric effect: they became distorted when an electric charge was applied.
- Piezoelectric effect - It is a phenomenon where specific types of material produce an electric charge proportional to the mechanical stress applied to them.
- The piezoelectric effect was discovered in 1880, in quartz.
- Quartz, topaz, etc. are few examples of piezoelectric crystals.
- Applications - Such crystals are used in cigarette lighters, electric guitars, TV remote controls, audio transducer.
- Quartz is the most famous piezoelectric crystal which is used in this capacity in analog wristwatches and clocks.

MPA in Antarctica
The Union minister of state for science and technology and earth sciences said that India will continue to support setting up 2 MPAs in Antarctica.
- A marine protected area (MPA) is a section of the ocean where a government has placed limits on human activity.
- An MPA provides protection for all or part of the protected marine area’s natural resources.
- It is managed for the long-term conservation of marine resources, ecosystem services or cultural heritage.
- Certain activities within an MPA are limited or prohibited to meet specific conservation, habitat protection, ecosystem monitoring, or fisheries management objectives.
- Marine protected areas can have many different names, including marine parks, marine conservation zones, marine reserves, marine sanctuaries, and no-take zones.
- Southern Ocean - The Southern Ocean that encircles Antarctica covers around 10% of the global ocean and is home to nearly 10,000 unique polar species.
- The Southern Ocean has 2 MPAs
- One in the southern shelf of the South Orkney Islands.
- The other in the Ross Sea.
- These fully protect only 5% of the ocean.
- All types of fishing, other than scientific research, are prohibited within the southern shelf of the South Orkney Islands MPA.
- Discharges and dumping from fishing vessels are also not allowed.
- In the Ross MPA, 72 % of the waters are closed to commercial fishing.
- Designation of MPAs - The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) is responsible for designating and regulating MPAs in the Southern Ocean.
- Proposed MPAs - Since 2012, the European Union and Australia have proposed an MPA in East Antarctica.
- An MPA was proposed in the Weddell Sea by the EU and Norway and in the waters surrounding the Antarctic Peninsula by Chile and Argentina.
- In 2021, India extended its support for designating East Antarctica and the Weddell Sea as MPA.

Conservation of Antarctic Marine Living Resources
- CCAMLR - CCAMLR is an international treaty to manage Antarctic fisheries to preserve species diversity and stability of the entire Antarctic marine ecosystem.
- CCAMLR came into force in April 1982. And India has been its permanent member since 1986.
- Its Members include 25 states and the European Union, which meet annually in Hobart, Australia.
- CCAMLR India coordinator - The Ministry of Earth Sciences and the Centre for Marine Living Resources and Ecology (CMLRE) in Kochi, Kerala.

Captive Employment Initiative
The Union Minister for Rural Development initiates ‘Captive Employment’ initiative under Deen Dayal Upadhyaya Kaushalya Yojana (DDU-GKY).

Muslim personal law on Inheritance
A Muslim couple from Kerala recently decided to get their marriage registered under the Special Marriage Act (SMA) to ensure their daughter's inheritance.
- The couple’s marriage under Special Marriage Act will enable their daughters to inherit the couple’s property under the Indian Succession Act, 1925.
