Protein from Budgett’s frog can block enzymes of disease-causing pathogens: Study

Budgett’s frog

  • Behaviour
    • Budgett’s frogs are highly intelligent and very aggressive.
    • When frightened, they inflate themselves, stand up on their short legs and if this doesn’t deter the potential predator, they lunge at them with an open huge mouth followed up by a shrill shriek.
    • During the dry season, Budgett’s frogs remain in burrows they dig in the bottoms of pools of water.
    • While in the burrow, they will shed several layers of skin from which to form a waterproof cocoon that will keep the frog moist.
  • They use their exceptional night vision and their sensitivity to movement when hunting food.
  • Habitat/range: They are found near or in permanent or seasonal bodies of water in Paraguay, Argentina and Bolivia.
  • Conservation Status
    • IUCN Red List: Least Concern

Key findings of the research

  • The peptides (short proteins) produced from the skin of amphibians have long been studied because of their ability to counter unfavourable conditions in the environment, including harmful pathogens.
  • The frog-secreted peptide inhibited two key enzymes called subtilisin carlsberg and proteinase K., produced by pathogens.
  • These enzymes play a pivotal role in promoting infections by degrading specific protective proteins of the infected person.
  • The peptide was shown to act through a slow-tight binding pathway, and was found to be as effective as SSI, a well-known subtilisin inhibitor.
  • The researchers show the formation of a Michaelis complex – a tight, noncovalent complex with the intact inhibitor – during the process.

Fight for Ghaggar''s rights: Residents

Ghaggar River

  • It is an intermittent river that flows only during the monsoon season.
  • Course:
    • It rises from the Shivalik Rangein northwestern Himachal Pradesh.
    • It flows about 200 miles (320 km) southwest through Haryana state, where it receives the Saraswati River.
    • It eventually dries up in the Thar Desertin Rajasthan.
  • This seasonal river feeds two irrigation canals that extend into Rajasthan. The Hakra, which flows in Pakistanis the continuation of the Ghaggar River in India, and they are together called the Ghaggar - Hakra River.
  • Historical Significance:
    • Several historians identify Ghaggar with the Vedic Saraswati River.
    • Along the banks of the Ghaggar River, many settlements of the Indus Valley Civilization have been excavated.
    • Hence it is believed that the ancient settlements on its banks are the creation of ingenious Vedic Aryans.
    • It is believed that the rivers Sutlej and Yamuna once flowed into the Ghaggar-Hakra river bed.
  • Tributaries: The main tributaries of the Ghaggar are the Kaushalya River, Markanda, Sarsuti, Tangri, and Chautang.

  • Key Updates and Features of YUVAi Programme:
    • Progressing in three phases, the YUVAi programme is being implemented in multiple cohorts to ensure that maximum students stand a chance to become future-ready. It introduces students to several social themes to direct their AI knowledge towards solving real-world problems.
    • In the first Cohort, more than 8,500 students registered, post which, they attended online orientation sessions to learn fundamental concepts of AI. Teachers also enrolled into the program and underwent orientation sessions. Students then submitted innovative AI-based ideas under one of the eight core themes of the programme.
    • In phase 2, Top 200 AI-based ideas were shortlisted. Shortlisted students attended online deep dive AI training and mentorship sessions with certified Intel AI coaches and experts – helping students enhance their solutions. Students then submitted their AI projects to be evaluated for Phase 3.
    • In Phase 3, top 50 students were shortlisted and they were invited to attend a four-day face-to-face rapid modeling workshop – receiving one-on-one mentorship, apprenticeship and guidance from industry experts to fine-tune their projects and develop them into prototypes.
    • An on-spot project presentation was conducted by a multiple jury panel to shortlist Top 10 students.

US F-16 crashes into Yellow Sea off South Korea, says Yonhap report

Yellow Sea

  • It is a marginal sea in the western Pacific Ocean.
  • Location:
    • It is situated between mainland China to the west and north, the Korean Peninsula to the east, and the Shandong Peninsula and Liaodong Peninsula to the south.
    • It is positioned to the north of the East China Sea.
  • The sea was named for the yellowish sand particles originating from the Gobi Desert that descend on the surface of the sea, thereby giving it a golden yellow color.
  • Size: Also referred to in China as Huang Hai and in North and South Korea as the West Sea, the Yellow Sea is 870 kilometres long and 556 kilometres wide, covering an area of 380,000 sq km.
  • Depth: It is one of the largest shallow areas of the continental shelf in the world, with an average depth of 44 metres and a maximum depth of 152 metres.
  • Inflow: The main rivers that drain into the Yellow Sea include the Hai River, the Yalu River, the Han River, the Taedong River, and the Yellow River.
  • Islands: The Yellow Sea is dotted with numerous islands, the largest of which include Jeju Island (South Korea), Shandong Peninsula islands (China), and Ganghwa Island (South Korea).
  • Climate: The climate is characterized by very cold, dry winters and wet, warm summers.
  • Currents:
    • The warm current of the Yellow Sea is a part of the Tsushima Current, which diverges near the western part of the Japanese island of Kyushu and flows at less than 0.5 mile (0.8 km) per hour northward into the middle of the sea.
    • Along the continental coasts, southward-flowing currents prevail, which strengthen markedly in the winter monsoon period, when the water is cold, turbid, and of low salinity.

Royal Bengal tiger spotted in Sikkim

  • The Royal Bengal Tiger was captured by trap cameras of a team of Bombay Natural History Society (BNHS) which is conducting a study in the sanctuary in collaboration with the Sikkim Forest department.
  • It was under a larger project called "Conservation and Use of Five Wetlands in three Himalayan States to secure Habitats of Birds Migrating within the Central Asian Flyway (CAF)."
  • This project was sanctioned under the National Mission on Himalayan Studies (NMHS), aims to protect and conserve wetland sites in Ladakh, Himachal Pradesh, and Sikkim.

Clam makes comeback from extinction off shores of Croatia.

Pinna nobilis

  • It is a large species of Mediterranean clam, a marine bivalve mollusc in the family Pinnidae.
  • The clams, whose shells can grow as much as 1.2 m across, play an important ecological role by filtering sea water and allowing other organisms to flourish.
  • It attaches itself to rocks using a strong byssus composed of many silk-like threads which used to be made into cloth.
  • The animal secretes these fibres from its byssus gland; they consist of keratin and other proteins and may be as long as 6 cm (2.4 in). The inside of the shell is lined with brilliant mother-of-pearl.
  • As with other members of its genus, Pinna nobilis hosts symbiotic shrimp which live inside its shell.
  • It is believed that when it sees a threat, the shrimp warns the host, perhaps by retracting its claws or even by pinching. The clam then closes shut.
  • It has been demonstrated that the shrimp has a similar filter-feeding diet to its host and the relationship is likely mutualistic.
  • Distribution: This species is endemic to the Mediterranean Sea.
  • Threats: It is relatively fragile to pollution and shell damage.
  • The clam, known as the noble pen shell or pinna nobilis, started dying out as a deadly pathogen spread in parts of the Mediterranean around 2016.
  • Conservation status
    • IUCN: Critically endangered
