- An ancient clay figurine from the Iron Age has recently been discovered in Lake Bolsena, Italy.
- About Lake Bolsena:
- Location: Lake Bolsena is situated in the northern part of the Viterbo province within the Lazio region of Italy.
- Size: It is the largest volcanic lake in Europe, covering an area of 113.5 square kilometers.
- Dimensions: The lake measures approximately 13.5 km (8.4 miles) in length and 12 km (7.5 miles) in diameter.
- Formation: The lake was formed about 370,000 years ago following the collapse of the caldera of the Vulsini volcano, which remained active until 104 BC.
- Unique Phenomenon: Lake Bolsena is known for a peculiar phenomenon called “sessa,” which causes tidal-like movements within the lake.
- Islands: The two islands, Martana and Bisentina, located in the southern part of the lake, were created by underwater volcanic eruptions.
- Shoreline: The lake’s shores are characterized by nearly pristine nature, featuring forests, reed beds, tranquil coves, as well as cultivated fields, olive groves, and vineyards.
- Nearby Towns: The towns of Capodimonte and Bolsena border the lake.
- What is a Volcanic Lake?
- A volcanic lake forms within a volcanic crater, caldera, or depression created by volcanic activity. These lakes typically emerge after a volcanic eruption, when the depression or crater fills with water from precipitation, groundwater, or melting ice and snow.
- Three Kashmiri scientists have recently identified a new species of hoverfly that mimics wasps in the high-altitude alpine forests.
- About Hoverflies:
- Hoverflies, also known as 'flower flies' or 'syrphid flies,' belong to a family comprising around 6,000 species within the fly order, Diptera. Their common names often reflect their behavior of hovering around flowers. These insects are found across the globe, inhabiting both temperate and tropical regions.
- Characteristics:
- Appearance: Hoverflies, with their yellow markings, resemble wasps or bees but lack the ability to bite or sting. They can be easily identified from wasps and bees by their single pair of wings.
- Distinguishing Features: They are distinguished from other flies by a false (spurious) vein that runs parallel to the fourth longitudinal wing vein. Hoverflies range in size and form, from small, elongated, and slender to large, hairy, and yellow-and-black.
- Head Structure: They have a typical fly head with short antennae and prominent, bulbous eyes.
- Beneficial Role:
- Pollination: Adult hoverflies feed on nectar and pollen, making them vital pollinators across various habitats.
- Pest Control: The larvae of many hoverfly species consume aphids, mites, and small insects, contributing to the control of these pests.
- Nutrient Recycling: Some hoverflies are effective at recycling nutrients in their environments.
- The Supreme Court has granted a stay on the recovery of an outstanding amount demanded by the income tax authorities, following a plea from the news portal NewsClick. This stay will remain in effect until the appeal filed with the Income Tax Appellate Tribunal (ITAT) is resolved.
- About the Income Tax Appellate Tribunal (ITAT):
- Establishment: ITAT is a quasi-judicial body established in January 1941 to handle appeals under the Direct Taxes Acts.
- Structure: Initially, ITAT had six members and three Benches located in Delhi, Kolkata (Calcutta), and Mumbai (Bombay). It has since expanded to 63 Benches across 27 cities, covering nearly all cities with High Court seats.
- Bench Composition: Each Bench comprises an accountant member and a judicial member. The ITAT President appoints the members to form a Bench, and in some cases, a special Bench with three or more members may be created for certain appeals.
- Function: ITAT acts as the final fact-finding authority in tax disputes, providing a platform for both taxpayers and the income tax authorities to resolve issues. It adjudicates appeals under the Income Tax Act of 1961 and operates under the Ministry of Law and Justice.
- Filing Appeals:
- Eligibility: Appeals can be filed by taxpayers challenging assessment orders or other decisions made by income tax authorities. The ITAT is commonly approached by taxpayers disputing orders from the Commissioner of Income-tax (Appeals).
- Department Appeals: Similarly, the income tax department can appeal against orders from the Commissioner of Income-tax (Appeals) before the ITAT.
- Finality and Further Appeals: ITAT’s decisions are final, with further appeals to the High Court permissible only if there is a substantial question of law. ITAT operates under the jurisdiction of the regional High Courts and must comply with their rules, while also being subordinate to the Supreme Court of India.

- Recently, the Deputy Governor of the Reserve Bank of India (RBI) announced that the RBI is currently reassessing the investment limits for foreign investors in the overnight index swap (OIS) market.
- About Overnight Index Swaps (OIS):
- Definition: An OIS is a derivative instrument where returns from a fixed-rate asset are exchanged for a predetermined published index of a daily overnight reference rate over an agreed period.
- Purpose: The main aim of an OIS is to manage interest rate risk, especially the risk arising from fluctuations in the overnight lending rate.
- Calculation: The overnight index swap rate is computed daily based on the average interest rate paid by institutions on loans tied to the overnight rate for that day.
- How OIS Works:
- Function: OIS instruments allow financial institutions to swap their interest payments without having to refinance or alter the terms of their existing loans.
- Mechanism: In an OIS transaction, one institution will swap an overnight (floating) interest rate, while the other will swap a fixed short-term interest rate.
- Settlement: At the end of the agreed period, the institution that has paid less interest compensates the other institution for the difference, based on the terms of the swap agreement.
- The Perseid meteor shower, one of the most anticipated celestial events of the year, is expected to reach its peak on August 11.
- About the Perseid Meteor Shower:
- Name Origin: The name "Perseid" is derived from the Perseus constellation, from which the meteors appear to radiate.
- Timing: The Perseids peak in mid-August annually and are renowned for their spectacular displays.
- Characteristics: Known for their swift and bright appearance, Perseid meteors often leave a luminous trail of light and color as they streak across the night sky.
- Frequency: It is one of the most prolific meteor showers, with up to 100 meteors visible per hour.
- Fireballs: The Perseids are notable for producing fireballs—intense bursts of light and color that persist longer than typical meteors. These fireballs originate from larger fragments of cometary material.
- Key Facts About Meteor Showers:
- Meteor Definition: A meteor is a space rock entering Earth's atmosphere.
- Process: As the meteor falls, friction with the air heats it significantly, causing it to glow.
- Visibility: The bright streak observed is due to the heated air around the meteor, not the meteor itself.
- Meteor Shower: When numerous meteors enter the atmosphere simultaneously, it results in a meteor shower.
- Speed: Meteors travel at extremely high speeds, often reaching tens of thousands of kilometers per hour, and disintegrate due to intense atmospheric friction.
