Ghost Particles or Neutrinos
- Context (The Hindu - TH): Scientists achieved the first-ever distant detection of neutrinos released from spent nuclear fuel, boosting non-proliferation monitoring against weapon misuse.
- Core Characteristics: Dubbed ghost particles, these charge-free, nearly massless subatomic entities pass through matter unhindered and travel without magnetic deflection.
- Production Sources: Naturally generated during stellar nuclear fusion in the Sun's core, as well as during artificial radioactive decay in earthbound power reactors.
- Detection Infrastructure: Specialized facilities like Antarctica's IceCube Neutrino Observatory utilize massive volumes of deep ice to capture rare particle interactions.
Nanobots for Breast Cancer Therapy
- Context (Press Information Bureau - PIB): Institute of Nano Science and Technology (INST) and BARC researchers created light-driven nanobots for targeted breast cancer treatment.
- Technological Design: Built with Upconversion Nanoparticles (UCNPs) and polydopamine, these bots feature folic acid coating to specifically bind with malignant cells.
- Operational Mechanism: Near-infrared (NIR) light powers deep tissue movement, converting light into localized heat to destroy tumors with minimal damage.
- Medical Significance: Offers a precise, minimally invasive therapy designed to treat deep-seated tumors while overcoming major drawbacks of traditional cancer treatments.
