In a landmark moment for India's space ambitions, Indian astronaut Shubhanshu Shukla has blasted off to the International Space Station (ISS) as part of the Axiom-4 mission , marking the country's return to human spaceflight after a 41-year hiatus . This historic launch from NASA’s Kennedy Space Center in Florida has not only reignited national pride but also officially kickstarted India’s human spaceflight programme . The mission, operated by Axiom Space , includes a four-member international crew that will spend 14 days in orbit , conducting scientific research, outreach programs, and various commercial activities. This momentous occasion places India among a select group of nations capable of sending humans into space and reflects the growing prowess of the Indian space sector . A New Chapter: Shubhanshu Shukla and India’s Astronautical Comeback The last Indian to go to space was Rakesh Sharma in 1984, aboard the Soviet spacecraft Soyuz T-11. Now, in 2025, Shubhanshu...
Nobel Prize in Medicine 2024: Discovery of MicroRNA and Gene Regulation Introduction The Nobel Prize in Physiology or Medicine 2024 has been awarded to Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNA (miRNA) and its crucial role in post-transcriptional gene regulation . This discovery has revolutionized our understanding of gene expression, cellular development, and disease mechanisms. We will delve into gene regulation , the function of microRNA , its implications in disease diagnostics, oncogenesis, and immune response , and the broader significance of this remarkable discovery. What is Gene Regulation? Gene regulation is the process by which cells control the timing, location, and amount of gene expression . This mechanism ensures that different cells (muscle cells, nerve cells, etc.) express unique sets of proteins , allowing them to perform specialized functions. Key Aspects of Gene Regulation: The human genome contains about 20,000 genes , bu...
