1.What is RoseTTAFold?
AI-based prediction tool RoseTTAFold has provided a major scientific breakthrough in the last four years in the area of computational drug development.
About RoseTTAFold:
- It is developed by researchers at the University of Washington, U.S.
- It uses generative diffusion-based architectures (one kind of AI model) to predict structural complexes.
- The tools’ neural networks use massive amounts of input data to produce the desired output — the three-dimensional structures of proteins.
- It uses deep learningto quickly and accurately predict protein structures based on limited information. Without the aid of such software, it can take years of laboratory work to determine the structure of just one protein.
- It is a "three-track" neural network, meaning it simultaneously considers patterns in protein sequences, how a protein's amino acids interact with one another, and a protein's possible three-dimensional structure.
- It has the capability to predict not just static structures of proteins and protein-protein interactions but also their ability to predict structures and interactions for any combination of protein, DNA, and RNA.
2. Bond Buyback
The Reserve Bank of India (RBI) has responded to tight liquidity conditions in the banking system by announcing a significant reduction in the government's treasury bill sales and introducing a new selection of bonds for the Centre's buyback operations.
About Bond Buyback:
- It is a process whereby the central government and state governments buy back their existing securities, by redeeming them prematurely, from the holders.
- Bond buybacks is a liability management tools widely used in government securities markets to manage refinancing and liquidity risks.
- It enables issuers to retire an outstanding debt before its maturity date against a cash payment.
- The objectives of buyback can be
- Reduction of cost (by buying back high coupon securities),
- Reduction in the number of outstanding securities and improving liquidity in the G-Secs market (by buying back illiquid securities) and
- Infusion of liquidity in the system.
What is a Bond?
- It is a debt instrument in which an investor loans money to an entity (typically corporate or government) which borrows the funds for a defined period of time at a variable or fixed interest rate.
- Bonds are used by companies, municipalities, states and sovereign governments to raise money to finance a variety of projects and activities. Owners of bonds are debt holders, or creditors, of the issuer.
3.Sea Otters
A new study offers a fuller understanding of the tool use by the Sea otters and utilizing rocks and other objects to break open hard prey by them.
About Sea Otters:
- It is a aquatic member of the weasel family, found along the coasts of the Pacific Ocean in North America and Asia.
- Habitat: It spends most of its time in the water but, in some locations, comes ashore to sleep or rest.
- Appearance: Sea otters have webbed feet, water-repellent fur to keep them dry and warm and nostrils and ears that close in the water.
- They generally eat food equal to about a quarter of their body weight daily as they prowl kelp forests and seagrass beds.
- Ecological significance
- It’s a keystone species, which means that the health of sea otters is a good indication of the health of other species and ecosystems nearby.
- It plays a crucial role in maintaining the balance of marine ecosystems. By preying on sea urchins, they help control the population of these spiny creatures.
- Without otters, sea urchins can overpopulate and decimate kelp forests. These kelp forests are vital habitats for a myriad of marine life, offering shelter and food for numerous species.
- The presence of sea otters helps sustain the biodiversity and health of these underwater forests.
- Conservation status
- IUCN Red List: Endangered

- It is approximately 900 km long and 500 km wide and covers roughly 410,000 square kilometers.
- It is bounded to the south by Somalia and the Socotra Islands (part of Yemen), north by Yemen, east by the Arabian Sea, and west by Djibouti.
- The gulf is connected to the Somali Sea to the south by the Guardafui Channel, and to the Red Sea on the west by the Strait of Bab el Mandeb.
- In the west, it narrows into the Gulf of Tadjoura, near Djibouti.
- It is demarcated from the Arabian Sea by the Horn of Africa and the Socotra Islands.

9. What is Plunging Region of a Black hole?
A strange area around black holes called the “plunging region” has been spotted for the first time.
What is a Black Hole?
- It is a cosmic body of extremely intense gravity from which nothing, not even light, can escape.
- This intense gravity occurs because a large amount of matter has been squeezed into a very small space.
- Formation:
- A black hole can be formed by the death of a massive star.
- When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star’s outer layers are blown away.
- The crushing weight of constituent matter falling in from all sides compresses the dying star to a point of zero volume and infinite density called the singularity.
- Event Horizon:
- The event horizon is the boundary around a black hole beyond which no light or other radiation can escape.
- Once an object crosses this boundary, it cannot escape the black hole's gravitational pull.
About Plunging Region of a Black Hole:
- It is an area where matter stops circling a black hole and instead falls straight in.
- It was predicted by Albert Einstein’s theory of general relativity.
- When any matter gets too close to a black hole, it rips apart and forms an orbiting ring around it called an accretion disc.
- General relativity predicts there should be an inner boundary to the accretion disc past which nothing can orbit the black hole and instead plunges towards the black hole at near the speed of light.
- The region where this occurs was named the "plunging region", within which it is impossible to stop the final descent past the black hole's event horizon.
- The plunging region is just outside the event horizon.
- Studying plunging regions could teach us about how black holes form and evolve, as well as reveal new information about the fundamental nature of space-time.
10. What is a Dyson Sphere?
Recently, an international team of researchers based in Sweden, India, the US, and the UK have devised a way to search for unimaginably complex extraterrestrial megastructures, known as Dyson spheres.
About Dyson Sphere:
- It is a hypothetical engineering project that only highly advanced civilizations could build.
- These Dyson spheres would allow a civilization to harness all of a star's energy.
- The prospect of such a construction was first proposed by physicist and astronomer Freeman J. Dyson back in 1960.
- He envisioned them as a solar-system-sized shell consisting of a 'swarm of objects'' that could travel on independent orbits around a star, such as our sun.
- The idea behind this is that the aliens commandeering this multi-faceted sphere would use it to harness the energy of the star to fulfil the energy needs of its technologically sophisticated people.
- Do Dyson spheres exist?
- Because of their infrared radiation, Dyson spheres are considered a type of technosignature—a sign of activity that distant astronomers could use to infer the existence of intelligent beings in the universe, according to a NASA report.
- A handful of Earth-based researchers have scanned infrared maps of the night sky in hopes of spotting Dyson spheres, but so far, nobody has seen anything out of the ordinary.
