Context: The mantis shrimp, a small 10-cm marine crustacean, is renowned for its extraordinary punching power. It strikes prey at 23 m/s using its dactyl club, generating shockwaves that can shatter hard shells and stun prey. Despite such force, the shrimp itself remains unharmed a biological mystery until now. Phononic Shielding Mechanism How It Works: Microstructure and Bandgaps Club Design and Dual Impact Force Layered Armor: Hierarchical Material Design Laboratory Simulation of Natural Impact Significance Future Applications and Biomimicry The mantis shrimp is not just a marine marvel — it’s an evolutionary engineer. Its ability to both withstand and manipulate extreme forces could revolutionize how we think about impact-resistant materials, protective gear, and wave dynamics. TH

Rising Paediatric Tuberculosis (TB) Cases in India
Overview of Paediatric TB Paediatric tuberculosis (TB) refers to tuberculosis infections in children. While TB is often thought of as an adult disease, it is a significant cause of illness and death in children, especially in areas with high TB burden. The disease can manifest in various ways, including pulmonary TB (affecting the lungs) and extrapulmonary TB (affecting other organs). Contributing Factors to the Surge Challenges in Reporting and Diagnosis Current Government Actions and Strategy Future Considerations The increasing incidence of paediatric TB in India points to multiple interconnected factors, including malnutrition, the COVID-19 impact, and drug resistance. While diagnostic advancements have led to higher reported cases, there are still significant challenges in early detection and underreporting. BS
