ANSWER: A

ANSWER: D

ANSWER: C

ANSWER: A

• Scientists have now detected atomic oxygen in a thin layer sandwiched between two other layers of the Venusian atmosphere.
• They noted that this atomic oxygen, which consists of a single oxygen atom, differs from molecular oxygen, which consists of two oxygen atoms and is breathable.
• The oxygen is produced on the planet’s day side by ultraviolet radiation from the sun that breaks down atmospheric carbon dioxide and carbon monoxide into oxygen atoms and other chemicals. Some of the oxygen is then transported by winds to the Venusian night side.
• They used an instrument aboard the SOFIA airborne observatory.

ABOUT VENUS

• Also called Earth’s twin.
• Venus, with a diameter of about 7,500 miles (12,000 km), is slightly smaller than Earth.
• Unlike Earth, where oxygen makes up about 21% of the atmosphere, Venus has a thick and noxious atmosphere dominated by carbon dioxide (96.5%), with smaller amounts of nitrogen and trace gases.
• It has no moons and rotates clockwise (east to west).
• It is the hottest planet due to “runaway greenhouse effect”.

ABOUT SOFIA

• It is a Boeing 747SP aircraft modified to carry an infrared telescope.
• It is a joint project between NASA and the German Aerospace Center.

ANSWER: B

• More than sixty years after it was last recorded, an expedition team has rediscovered an iconic, egg-laying mammal in one of the most unexplored regions of the world.

ABOUT THE SPECIES

• Scientific name– Zaglossus attenboroughi
• Attenborough’s long-beaked echidna, named after famed broadcaster Sir David Attenborough, was captured for the first time in photos and video footage using remote trail cameras set up in the Cyclops Mountains of Indonesia’s Papua Province.
• It was last seen in 1961.
• It belongs to the monotreme group of mammals, known for their unique characteristic of laying eggs.
  • This echidna is one of the five surviving monotreme species.
• Echidnas are notoriously difficult to find since they are nocturnal, live in burrows, and tend to be very shy.
• Attenborough’s long-beaked echidna has never been recorded anywhere outside the Cyclops Mountains.
• It is currently classified as Critically Endangered on the IUCN Red List of Threatened Species.

ANSWER: B

• The current Israel-Palestine crisis in the Middle East has refocused attention on the ambitious Ben Gurion Canal Project.
• The idea is to cut a canal through the Israeli-controlled Negev Desert from the tip of the Gulf of Aqaba — the eastern arm of the Red Sea that juts into Israel’s southern tip and south-western Jordan — to the Eastern Mediterranean coast
• It will create an alternative to the Egyptian-controlled Suez Canal that starts from the western arm of the Red Sea and passes to the southeastern Mediterranean through the northern Sinai peninsula.
• This so-called Ben Gurion Canal Project, which was first envisioned in the 1960s would, if it were to be actually completed, transform global maritime dynamics by taking away Egypt’s monopoly over the shortest route between Europe and Asia.

ANSWER: C

• Recently, a new island emerged near Japan’s Ogasawara island chain.
  • The Ogasawara island chain, also known as the Bonin Islands, constitutes a volcanic arc comprising over 30 islands and islets, some of which remain volcanically active.
• An unnamed undersea volcano recently erupted about half a mile off the southern coast of Iwo Jima. Just 10 days later, there was enough debris on the shallow seabed to allow a new island—formed of volcanic ash and splintered rocks—to poke 66 feet above the ocean’s surface.
• The island is about 100 meters in diameter, standing 20 meters above the sea less than a mile off Iwo Jima island.
• The island took shape through phreatomagmatic eruptions.
• The term “phreatomagmatic” combines “phreatic,” relating to water, and “magmatic,” referring to magma.
• These eruptions are actually triggered when magma reacts with seawater, thereby resulting in explosive releases of ash and steam.

ANSWER: A

• Amid the challenges of paddy stubble burning and air pollution in Delhi- NCR region, the Indian Agricultural Research Institute, Delhi has developed a high-yielding short-duration variety namely Pusa-2090 which will help in dealing with the menace.
• The new paddy variety is an improved version of currently used Pusa-44.
• PUSA-2090 variety matures in only 120 to 125 days as compared to Pusa-44 which takes 155 to 160 days to mature.
• The new paddy variety will give around 30 days time to farmers to ready their fields for the next crop.
• It was developed by crossing Pusa-44 with CB-501, an early-maturing Japonica rice line known for stronger stems and higher grain production.

ANSWER: D

• The 4^th edition of the Bilateral Exercise between the Indian Navy and Bangladesh Navy, BONGOSAGAR-23, and the 5th edition of Coordinated Patrol (CORPAT) by the two navies were held at Visakhapatnam.
• Ships and aircraft from both navies undertook joint patrolling along the International Maritime Boundary Line and maritime exercises to enhance interoperability.
• Indian Navy Ships Kuthar, Kiltan and Maritime Patrol Aircraft (MPA) Dornier participated in the exercise.
• The ships undertook communication drills, surface gun-shoots, tactical maneuvers and other exercises.
• CORPAT-23 also included the maiden Humanitarian Assistance and Disaster Relief drills held between the two navies.

ANSWER: B

• World Kindness Day is observed globally to promote and celebrate acts of kindness on November 13^th.
• The theme for the year 2023 is a powerful reminder – “Be Kind Wherever Possible.”

• The centuries-old annual “Pathron Ka Mela” (stone-pelting fair), a unique festival held a day after Diwali, was celebrated at Dhami, about 30 km from Shimla.
• The festival, marked by pelting of stones between two groups of villagers, started in the presence of the former ruler of Dhami known as Halog and lasted for 50 minutes.
  • It ended when a person sustained a minor injury which caused bleeding.
• As per the tradition, the stone pelting takes place between residents of Halog and Jamog who line up on either side of a circular structure and pelt small stones at each other.
• The fair begins when the priest of Narsingh Devta temple walks to the Kali Devi temple accompanied by a team of musicians.
• As per traditions, the festival continues till blood starts oozing from the wounds of the injured people. The villagers smear “tilak” of blood on the forehead of goddess Kali.
