GKToday Testbook Current Affairs Adda - Questions & Answers
Ans. XPoSat (X-ray Polarimeter Satellite) is India's first dedicated polarimetry mission, designed by ISRO to study X-ray emissions from astronomical objects, providing insights into cosmic phenomena like black holes, neutron stars, and pulsars.
Ques. What are lagrange points?
Ans. Lagrange points are five specific positions in space where gravitational forces and orbital motion balance. These points allow objects to remain stable relative to two larger celestial bodies, like Earth and the Sun, aiding satellite placement.
Ques. What is overdose reduction?
Ans. Overdose reduction involves strategies like promoting harm reduction, educating about drug risks, expanding access to naloxone, improving mental health support, offering addiction treatment, and monitoring prescription drugs to prevent misuse and save lives effectively.
Ques. What is the Jeju Air passenger jet tragedy?
Ans, A Jeju Air passenger jet tragically crashed while attempting to land at Muan International Airport, South Korea, in 2024. The accident resulted in 179 fatalities, marking one of the year's deadliest aviation disasters.
Ques. Why is Notre Dame Cathedral in the news?
Ans. Notre Dame Cathedral in Paris made headlines in 2024 as it reopened after extensive restoration following the 2019 fire. The historic event included the iconic bells ringing again, symbolizing resilience and cultural preservation.
Ques. Which is the largest known genome?
Ans. The fern with the largest known genome is Ophioglossum reticulatum, the "adder 's-tongue fern." Its genome is significantly larger than that of humans, containing around 150 billion DNA base pairs.
Ques. What is deep learning?
Ans. Deep learning is a branch of machine learning that employs artificial neural networks with multiple layers to analyze vast amounts of data. It is used for tasks like image recognition, natural language processing, and predictive modelling.
Ques. Who is the 'Godfather of Deep Learning?'
Ans. Known as the 'Godfather of Deep Learning,' Hinton received the Nobel Prize in Physics for his foundational research in neural networks, which has been pivotal in AI development.
