Scientists at the ICAR-National Bureau of Fish Genetic Resources (NBFGR) working on sea anemones of the Lakshadweep group of islands have found mass anemone bleaching off the Agatti island.

• It is an invertebrate aquatic animal marked by soft bodies and has an ability to sting. They are close associates of corals and live rocks.
• It is an ocean-dwelling members of the phylum Cnidaria.
• It has a sticky foot or disc that allows them to anchor to rocks on the sea bottom or on coral reefs.
• They have stinging cells which are equipped with organelles known as nematocysts that contain small threads which are forcefully everted when stimulated mechanically or chemically.
• They are known to form symbiotic relationships with other animals; their most well-known alliance is with clownfish.
• They make their homes within the anemone’s tentacles, protected from predators; in return, the anemone eats the clownfish’s leftover meals.
• Anemones can have anywhere from a dozen to a few hundred tentacles. These cnidarians come in a variety of colors, decorating a tide pool or reef like a garden of wildflowers.
• Some species of sea anemones also have a relationship with Hermit crabs. The anemone will attach itself to the crab’s shell and be carried around to find more food, while the crab uses the anemone as protection from its predators.

Hence only statement 2 is correct.

Delegates at 19th Session of the United Nations Forum on Forests (UNFF19) entered into informal negotiations over the draft texts of the High-Level Declaration.

In the ongoing conflict in Ukraine, Russia's utilization of the Lancet Kamikaze drone, which incorporates American AI technology, highlights complex global supply chain issues. 

• These are small, unmanned aircraft packed with explosives that can be flown directly at a tank or a group of troops that are destroyed when it hits the target and explodes.
• These are also called as Switchblade drones.
• The name comes from the World War 2 era’s feared Japanese kamikaze pilots, who conducted suicide attacks by intentionally crashing their explosive filled aircraft into enemy targets.
• Features
• The modern drone versions have the capability of surpassing traditional defences to strike their targets and are also cheaper than their larger counterparts.
• The small lethal drones are difficult to detect on radar, and through the use of facial recognition, can be programmed to hit targets without human intervention.
• Although the US Kamikaze might be the most advanced in this class of drones, Russia, China, Israel, Iran and Turkey all have some versions of it.

What is Lancet-3 drone?

• It is a type of loitering munition, integrates the Jetson TX2 — described by Nvidia as the most power-efficient embedded AI computing device.

A new study urges caution in the development of Artificial Intelligence (AI) chatbots designed to mimic deceased loved ones, known as ‘deadbots’.

• These are also known as griefbots, are AI-enabled digital representations of departed loved ones.
• Working: These chatbots simulate their language patterns and personality traits using their digital footprint, like emails, social media posts and even voice recordings, to create a conversational AI that reflects their personality. 
• Issues:
• Researchers have warned that these chatbots, while potentially comforting, could lead to psychological distress if not designed with safety in mind.
• Solutions that might be enthusiastically adopted in one cultural context could be completely dismissed in another.

What is Conversational AI?

• It is a type of artificial intelligence (AI) that can simulate human conversation.
• It is made possible by natural language processing (NLP), a field of AI that allows computers to understand and process human language and Google's foundation models that power new generative AI capabilities.
• It works by using a combination of natural language processing (NLP), foundation models, and machine learning (ML).
• These AI systems are trained on large amounts of data, such as text and speech.
• This data is used to teach the system how to understand and process human language. The system then uses this knowledge to interact with humans in a natural way. It’s constantly learning from its interactions and improving its response quality over time.

Hence both statements are correct.

Two baby girls diagnosed with Kawasaki disease were successfully treated at Coimbatore Medical College and Hospital (CMCH) very recently.

About Kawasaki Disease:

• Kawasaki disease is a rare heart condition that causes a high fever and inflammation of the blood vessels.
• It usually affects children under the age of 5.
• It's one of the leading causes of heart disease in kids.
• The condition causes the immune system to attack blood vessels, which become inflamed and swollen.
• Kawasaki disease tends to affect the coronary arteries, which carry blood to the heart muscle. 
• It can also cause problems with lymph nodes, skin, and the lining of a child's mouth, nose, and throat.
• Clinical signs include fever, rash, swelling of the hands and feet, irritation and redness of the whites of the eyes, swollen lymph glands in the neck, and irritation and inflammation of the mouth, lips, and throat.
• The disease was first described in Japan by Tomisaku Kawasaki in 1967, and the first cases outside of Japan were reported in Hawaii in 1976.
• The cause of Kawasaki disease is unknown, although more cases happen in late winter and early spring. 

Hence only statement 1 is correct.

Neural Processing Units are gaining importance in the semiconductor industry.

About Neural Processing Units (NPU): 

• An NPU, or a Neural Processing Unit, is a dedicated processor designed specifically for accelerating neural network processes.
• A neural network is essentially a type of machine learning algorithm that mimics the human brain for processing data.
• Therefore, the NPU is highly capable for handling machine learning operations that form the basis for AI-related tasks, such as speech recognition, natural language processing, photo or video editing processes like object detection, and more.
• In most consumer-facing gadgets, such as smartphones, laptops, and tablets, the NPU is integrated within the main processor, adopting a System-on-Chip (SoC) configuration.
• However, for data centres, the NPU might be an entirely discrete processor, separate from any other processing unit such as the central processing unit (CPU) or the Graphics Processing Unit (GPU).
• How is NPU different from CPU and GPU?
• CPUs employ a sequential computing method, issuing one instruction at a time, with subsequent instructions awaiting the completion of their predecessors.
• In contrast, the NPU harnesses parallel computing to simultaneously execute numerous calculations. This parallel computing approach results in swifter and more efficient processing.

Hence both statements are correct.

Panama is on the verge of a dramatic change to its immigration policy that could reverberate from the dense Darien jungle to the U.S. border.

About Panama:

• It is a country in Central America located on the Isthmus of Panama, the narrow bridge of land that connects North and South America.
• It is bordered by Costa Rica and Colombia and is situated between the Caribbean Sea and the North Pacific Ocean. 
• Embracing the isthmus and more than 1,600 islands off its Atlantic and Pacific coasts, the tropical nation is renowned as the site of the Panama Canal, which cuts through its midsection.
• Most Panamanians are descended from indigenous, or native, people, Europeans, Afro-Caribbeans, and immigrants from all over the world.
• Panama has the largest rainforest in the Western Hemisphere outside the Amazon Basin.
• Capital: Panama City
• Language: Spanish

What is the Panama Canal?

• It is a constructed waterway that connects the Atlantic and Pacific oceans across the Isthmus of Panama.
• It is one of the two most strategic artificial waterways in the world, the other being the Suez Canal. 
• It is approximately 80 kilometers long.
• The canal was built by the United States between 1904 and 1914, and it was officially opened on August 15, 1914.
• It is owned and administered by the Republic of Panama since the oversight of the Canal was transferred from the United States to Panama in 1999.
• The Panama Canal consists of a series of locks that raise and lower the water level to facilitate the passage of ships through the continental divide.

Hence only statement 2 is correct.

Results from a new clinical trial shed light on the performance of infusions of immune-calming regulatory T cells for children with type 1 diabetes. 

About T Cells:

• T cell is a type of white blood cell.
• It is also called T lymphocyte and thymocyte.
• T cells are part of the immune system and develop from stem cells in the bone marrow.
• They help protect the body from infection and may help fight cancer.
• There are two main types:
• Cytotoxic T-cells: Destroy infected cells.
• Helper T-cells: Send signals that direct other immune cells to fight infection.
• Rather than generically attack any antigens, T cells circulate until they encounter their specific antigen.
• T-cells have many identical T-cell receptors that cover their surfaces and can only bind to one shape of antigen.
• When a T-cell receptor fits with its viral antigen on an infected cell, the Killer T-cell releases cytotoxins to kill that cell.

Hence only statement 2 is correct.

Scientists studying the sperm whales have described for the first time the basic elements of how they might be talking to each other.

About Sperm Whale:

• It has small paddle-like flippers and a series of rounded humps on its back.
• Lifespan: Up to 60 years
• They are highly social mammals that communicate with one another using a series of clicks called codas, and that each coda has a distinct purpose.
• Ambergris, a material sometimes found floating in the sea, is formed in the sperm whale’s intestines around a core of undigested solid matter such as squid beaks.

Hence only statement 1 is correct.

The Union Ministry of Environment Forest and Climate Change recently notified Captive Elephant (Transfer or Transport) Rules, 2024.

Captive Elephants under the Wildlife Protection Act (WPA), 1972:

• Elephants are, according to the provisions of the WPA, a Schedule 1 species, and therefore, be it wild or captive, cannot be captured or traded under any circumstances.
• Section 12 of the Act allows Schedule I animals to be translocated for ‘special purposes’ such as education and scientific research.
• They can also be translocated for population management of wildlife without harming any wild animals and the collection of specimens for recognised zoos/museums.
• Captive elephants, because of their historical role in forest management, timber transport, presence in estates of erstwhile royal families and in temple precincts for religious purposes can be owned and therefore come under a special category. However, strict rules guide the transfer of such elephants.
• Section 40(2) of the WPA prohibits the acquisition, possession, and transfer of a captive elephant without the written permission of the Chief Wildlife Warden(CWW) of the State. 
• The Environment Ministry in 2021 brought in an amendment that allowed the transfer of elephants for ‘religious or any other purposes’.

Captive Elephant (Transfer or Transport) Rules, 2024:

• It lays down the procedure to be followed for the transfer of captive elephants within a State or between two States.
• The notification authorises the CWW of States and UTs to permit or reject the transfer of captive elephants. 
• The CWW shall permit the inter and intra-State transfers if the owner of the elephant is no longer in a position to maintain it or if the animal will have a better upkeep than in the present circumstances.
• The transfer of captive elephants won’t be permissible unless the genetic profile of the animal has been entered in the electronic monitoring application of the MoEFCC (Ministry of Environment, Forest and Climate Change). 
• The application for transfer of captive elephants should be made to the Deputy Conservator of Forests (DCF), having jurisdiction over the area where the elephant is registered. 
• The DCF will conduct an inquiry and physical verification of the facility where the elephant is presently housed, and also the facility where the elephant is proposed to be housed and obtain a certificate of a veterinary practitioner, and then forward the details to the CWW, who within seven days will accept or reject the transfer.

Hence option b is the correct answer.
