[A] Google
[B] Meta
[C] Microsoft
[D] Amazon
Show Answer
Correct Answer: A [Google]
Notes:
At the I/O Developers Conference 2025, Google launched its AI-first restructuring strategy called AI Matryoshka. AI Matryoshka is a multi-layered artificial intelligence ecosystem where Google’s core AI acts like the central brain, similar to a Matryoshka doll. It is built around Gemini 2.5 models and aims to change how users, developers, and enterprises interact with technology. This system powers everything from Application Programming Interfaces (APIs) to user-facing apps. The goal is to deeply embed AI across all Google platforms and create smart, autonomous systems that respond in real time.
44. What is the primary objective of a Thrombectomy?
[A] Remove blood clots and restore blood flow
[B] Reduce cholesterol levels
[C] Lower blood pressure
[D] None of the Above
Show Answer
Correct Answer: A [Remove blood clots and restore blood flow]
Notes:
The Technology Development Board (TDB), under the Department of Science and Technology (DST), has announced financial support for India’s first indigenous thrombectomy device. This support aims to improve stroke care by promoting homegrown medical technology. A thrombectomy is a medical procedure to remove blood clots from arteries or veins. These clots, called thrombi, can block blood flow and damage tissues or organs. Thrombectomy helps restore proper blood circulation and prevents serious health risks.
45. Arsia Mons is a massive shield volcano located in which planet?
[A] Mars
[B] Saturn
[C] Jupiter
[D] Neptune
Show Answer
Correct Answer: A [Mars]
Notes:
NASA’s 2001 Mars Odyssey orbiter recently captured a breathtaking image of Arsia Mons volcano rising above early morning clouds on Mars. Arsia Mons is a giant shield volcano in the Tharsis region of Mars. It stands over 18 kilometers tall and spans more than 300 kilometers wide at its base. It is much larger than Earth’s tallest volcano, Mauna Loa, which is 9 kilometers high. Arsia Mons is the southernmost volcano in the Tharsis Montes group, which includes three major volcanoes.
46. Indian Council of Medical Research has recently launched its first high-performance computing facility NAKSHATRA at which institute?
[A] Indian Institute of Science, Bengaluru
[B] National Institute of Communicable Diseases, Delhi
[C] National Institute of Virology, Pune
[D] All India Institute of Medical Sciences, Delhi
Show Answer
Correct Answer: C [National Institute of Virology, Pune]
Notes:
Indian Council of Medical Research (ICMR) has recently launched its first high-performance computing facility named NAKSHATRA at the National Institute of Virology (NIV) in Pune. NAKSHATRA was developed under the PM Ayushman Bharat Health Infrastructure Mission (PMABHIM). It is a modern computing cluster designed to boost storage and streamline processes for genomic research. The facility aims to improve early detection of disease threats and ensure faster response to outbreaks. It will also support Artificial Intelligence (AI)-driven vaccine and drug development for better public health outcomes.
47. What is “Gwada negative” that was recently mentioned in news?
[A] Asteroid
[B] Traditional medicine
[C] Spider
[D] Blood group system
Show Answer
Correct Answer: D [Blood group system]
Notes:
Recently, France’s national blood agency, the French Blood Establishment (EFS), discovered a new blood group system called “Gwada negative,” officially recognised by the International Society of Blood Transfusion (ISBT). It is scientifically named EMM-negative and registered as ISBT042. The name “Gwada negative” refers to the Guadeloupean origin of the woman who carries this rare blood type. This blood group is defined by the absence of the EMM antigen, a high-incidence antigen usually present in almost all humans.
48. What is the new term coined by researchers to describe extended periods of atmospheric thirst?
[A] Heatwave
[B] Dryburst
[C] Thirstwave
[D] Aridstorm
Show Answer
Correct Answer: C [Thirstwave]
Notes:
Researchers have recently introduced a new term called “Thirstwaves” to describe long periods of high atmospheric thirst. A Thirstwave occurs when the daily evaporative demand stays above the historical 90th percentile for at least three consecutive days. Evaporative demand means how thirsty the atmosphere is or how much water it wants to absorb from the ground or plants. It is influenced by temperature, wind speed, humidity, and sunshine. Understanding thirstwaves can help farmers manage water more efficiently and boost crop production. This concept is important for improving climate resilience in agriculture and water planning.
49. Which organization has launched the new AI model named AlphaGenome for studying human DNA?
[A] Microsoft
[B] Google DeepMind
[C] Meta
[D] Amazon
Show Answer
Correct Answer: B [Google DeepMind]
Notes:
Recently, Google DeepMind launched a new Artificial Intelligence model called AlphaGenome. AlphaGenome aims to predict accurately how individual mutations in human Deoxyribonucleic Acid (DNA) affect their functions and impact human health. It is built on DeepMind’s earlier genomics model named Enformer and works alongside AlphaMissense, which focuses on classifying the effects of variants in protein-coding regions. The model can analyze very long DNA sequences up to one million base pairs and generate highly detailed predictions.
