1. Global Declaration for River Dolphins
In a ground-breaking development, 11 Asian and South American countries recently signed a global declaration, the "Global Declaration for River Dolphins," aimed at preserving the world's six remaining river dolphin species.
About the Global Declaration for River Dolphins:
- This declaration is designed to guide 14 nations where river dolphins inhabit, with a focus on responsible freshwater dolphin conservation.
- It aims to halt the decline of all river dolphin species and increase the most vulnerable populations.
- The declaration will escalate collaborative endeavours to safeguard the surviving river dolphin species.
- Countries that adopted the declaration include Bangladesh, Bolivia, Brazil, Cambodia, Colombia, Ecuador, India, Nepal, Pakistan, Peru, and Venezuela.
- The countries involved agreed to improve water quality in the dolphins' habitat, create protected areas, tackle overfishing, and involve Indigenous communities in the affected regions in protecting the animals.
Key facts about river dolphins:
- River dolphins are any of six species of small, usually freshwater aquatic mammals that are related to whales (Order Cetacea).
- A seventh river dolphin species, the Chinese river dolphin, or baiji, was declared extinct in 2007.
- Distribution: These dolphins are found in rivers of south-central Asia, China, and South America and in the coastal waters of Brazil, Argentina, and Uruguay.
- Common Features: They have slender beaks lined with lots of teeth, small eyes, flexible necks and bodies, pronounced forehead melons, large flippers, and small dorsal fins.
- The six surviving species of river dolphins are the Amazon, Indus, Ganges, Irrawaddy, Tucuxi, and Yangtze finless porpoises.
- All six species of river dolphins are classified as Endangered or Critically Endangered on the IUCN Red List of Threatened Species.
- The largest is the Amazon River dolphin (Inia geoffrensis).
- They are important indicators of the health of rivers. Where freshwater dolphin populations are thriving, it is likely that the overall river systems are flourishing.
2. Bering Sea
A recent study links a decline in sea ice moving from the Arctic to the Bering Sea in the north Pacific Ocean to an increased occurrence of wildfire hazards in northeast China.
About Bering Sea:
- It is a marginal sea in the northernmost part of the Pacific Ocean, separating the continents of Asia and North America.
- To the north, the Bering Sea connects with the Arctic Ocean through the Bering Strait, at the narrowest point of which the two continents are about 53 miles (85 kilometres) apart.
- It is bordered by the US state of Alaska to the east and northeast, the Kamchatka Peninsula and the Far Eastern region of Russia in the west, and the chain of the Aleutian Islands in the south.
- The boundary between the United States and Russia passes through the sea and the strait.
- The Bering Sea can be divided into two equal portions: a shallow area along the continental shelf in the northern and eastern parts of the sea, and a deeper area in its southwestern part.
- The Bering Strait is a relatively shallow passage, averaging 100 to 165 feet (30 to 50 metres) in depth.
- Canyons:
- There are about 16 submarine canyons in the Bering Sea.
- Situated in the sea’s center is a large underwater canyon known as the Zhemchug Canyon. It is also the world’s largest and deepest submarine canyon.
- Rivers: The two rivers that drain into the sea are the Anadyr and the Yukon Rivers.
- Islands:
- In addition to the Aleutian and Komandor groups, there are several other large islands in both the sea and strait.
- These include Nunivak, St. Lawrence, and Nelson islands in Alaskan waters and Karagin Island in Russian waters.
- Springtime in the Bering Strait brings one of the largest migrations in the world. Each year, millions of birds and hundreds of thousands of marine mammals follow retreating sea ice north through the Bering Strait.
3. Neolithic Age
A rock art dating back to the Neolithic period was recently found in the Palnadu district of Andhra Pradesh.
About the Neolithic Age:
- The Neolithic Age, also called the New Stone Age, is the final stage of cultural evolution or technological development among prehistoric humans.
- The term Neolithic is most frequently used in connection with agriculture, which is the time when cereal cultivation and animal domestication were introduced.
- Because agriculture developed at different times in different regions of the world, there is no single date for the beginning of the Neolithic age. In India, the starting point of the Neolithic is generally thought to have occurred sometime around 7000 BCE.
- The Neolithic followed the Mesolithic Period and preceded the Chalcolithic Age, or the early period of metal tools.
- Features of the Neolithic Age:
- It was characterised by stone tools shaped by polishing or grinding, dependence on domesticated plants or animals, settlement in permanent villages, and the appearance of such crafts as pottery and weaving.
- The houses were built of mud and reed in rectangular or circular shapes.
- End of the Neolithic Age:
- Towards the end of the Neolithic era, copper metallurgy is introduced, which marks a transition period to the Bronze Age, sometimes referred to as the Chalcolithic or Eneolithic Era.
- In time, bronze became the primary material for tools and weapons, and a good part of the stone technology became obsolete, signalling the end of the Neolithic and thus of the Stone Age.
- Some of the important Neolithic sites in India include Burzahom in Kashmir, Chirand in Bihar and Edakkal caves in Kerala.
4. Lorrainosaurus
The fossils of a 170-million-year-old ancient marine reptile named ‘Lorrainosaurus’ from the Age of Dinosaurs have been recently identified as the oldest-known mega-predatory pliosaur.
Why in the news?
- Scientists first unearthed this sea monster's fossils in 1983.
- But in a new study, researchers re-analyzed the remains and found that the predator belonged to a previously unknown genus (group) of species and represented the oldest "megapredatory" pliosaur on record.
- The fossils were unearthed in the former region of Lorraine (now part of Grand Est) in northeastern France.
About Lorrainosaurus:
- It is the oldest mega-predatory pliosaur.
- It lived during the ancient Middle Jurassic era in marine environments.
- The regions in which it lived 170 million years ago are now located in northern France.
- This giant reptile probably reached over 6 meters from snout to tail.
- The animal had jaws over 1.3 m long with large conical teeth and a bulky ‘torpedo-shaped’ body propelled by four flipper-like limbs.
- They were ecological equivalents of today’s killer whales and would have eaten a range of prey, including squid-like cephalopods, large fish, and other marine reptiles.
What are pliosaurs?
- Pliosaurs were a type of short-necked plesiosaur: marine reptiles built for speed compared to their long-necked cousins.
- Also known as pliosauroids, these creatures were not dinosaurs but distant cousins of modern turtles.
- They had four large flippers, large heads, extremely powerful jaws, and enormous teeth, and they hunted fish, cephalopod mollusks, and other marine reptiles.
- They lived between 220 million years ago (Triassic period) and 70 million years ago (Cretaceous period) and were mostly found in the prehistoric seas that covered modern-day Europe.
- Famous examples, such as Pliosaurus and Kronosaurus, some of the world’s largest pliosaurs, were absolutely enormous, with body lengths exceeding 10 m.

- The basic idea of this fight is to capture the procession idol.
7. Betelgeuse star
Scientists resolved the mystery behind the sudden dimming of the supergiant Betelgeuse star and dismissed theories that suggested that the star might be entering the last stage of its evolution.
About the Betelgeuse star:
- It is a red supergiant starwith a distinctive orange-red hue.
- It is roughly 10 million years old and much younger than Sun.

- Betelgeuse has been classified as a "semiregular variable star," which is a type of variable star that periodically waxes and wanes in brightness and occasionally undergoes irregular light changes.
- Betelgeuse, typically, has a 400-day cycle as well as a longer cycle that stretches about 5 years.
