Biomarkers: The Future of Precision Medicine

What is a Biomarker?

A biomarker (biological marker) is an objective indicator of biological processes occurring in a cell or organism. These markers are typically detected through biological molecules found in blood, body fluids, or tissues.

Types of Biomarkers

  1. Diagnostic Biomarkers – Used to detect diseases early (e.g., cancer biomarkers in blood).
  2. Prognostic Biomarkers – Predicts disease progression and outcomes.
  3. Predictive Biomarkers – Helps determine a patient's response to specific treatments.
  4. Pharmacodynamic Biomarkers – Measures how well a patient responds to treatment.

Key Applications of Biomarkers

✔ Disease Diagnosis:

  • Non-invasive cancer detection using metabolites.
  • Early detection of conditions like Alzheimer's, cardiovascular diseases, and infections.
    ✔ Personalized Medicine:
  • Tailors treatments based on an individual's genetic or molecular profile.
  • Identifies which patients will benefit most from a particular therapy.
    ✔ Tracking Disease Progression:
  • Monitors how well a patient is responding to a treatment.
    ✔ Drug Development & Safety:
  • Used in clinical trials to evaluate the effectiveness of new drugs.

Recent Discovery in India

  • Researchers in India have identified common metabolites across cancers like pancreatic and lung cancer, which can serve as universal cancer biomarkers.
  • These metabolites help in early diagnosis, tracking disease progression, and improving treatment strategies.

Future of Biomarkers

1. AI and machine learning are being integrated for faster and more accurate biomarker identification.
2. Liquid biopsy techniques are improving non-invasive cancer detection.
3. Expanding the scope of biomarkers to neurodegenerative diseases, autoimmune conditions, and metabolic disorders.

IN-SPACe CANSAT & Model Rocketry India Student Competition 2024–25: A Giant Leap for Student Innovation

By
In a remarkable step towards strengthening India’s STEM education framework, the Astronautical Society of India (ASI), in collaboration with the Indian Space Research Organisation (ISRO) and the Indian National Space Promotion and Authorization Center (IN-SPACe), has launched the IN-SPACe CANSAT and Model Rocketry India Student Competition 2024–25 . This unique competition is crafted for undergraduate students across India, providing them with an opportunity to engage in experiential learning through the design, fabrication, and launch of CANSATs—can-sized satellites—using model rocketry platforms. The event held on June 14, 2025 , in Tamkuhi Raj, Kushinagar, Uttar Pradesh , was not a full-fledged rocket launch carrying an actual payload. Instead, it served as a critical site and systems validation test in preparation for the upcoming national student competition. This test focused on ensuring the readiness of launch site infrastructure, safety protocols, telemetry systems, and track...

A Deep Dive into ISRO’s Gaganyaan Mission

By
As the Indian Space Research Organisation (ISRO) advances steadily towards launching its maiden human spaceflight mission — Gaganyaan — the emphasis on spaceflight safety has never been more crucial. India is on the brink of joining an elite group of nations capable of sending humans to space, and ISRO is leaving no stone unturned to ensure that every stage of the mission, from liftoff to landing, adheres to global safety standards. Gaganyaan is poised to become a landmark achievement in India’s space exploration journey. It aims to send three astronauts into low Earth orbit (LEO) for up to seven days. While this initial mission is not intended to dock with any space station, the selected crew is being familiarized with docking procedures , a forward-thinking move that prepares them for potential future missions involving orbital rendezvous and space station docking . Ensuring astronaut safety is a complex, multilayered process involving extensive planning, rigorous testing, and ...
