Scientists are discovering that gray hair may not be permanent. Breakthrough research shows that pigment-producing cells can become trapped, not depleted. Studies indicate that stress can influence graying and its reversal. This opens possibilities for future treatments beyond hair dye. The science is paving the way for new biological solutions for gray hair.

New research reveals western India's savannas are ancient natural ecosystems. Historical texts from the 13th century describe open, grass-rich landscapes. This challenges the long-held view of these areas as degraded forests. Conservation efforts, particularly tree planting, may be harming these established environments. Understanding this history is crucial for effective protection.

Indian-origin Vandi Verma is at the helm of a groundbreaking NASA achievement: Mars rover Perseverance's first AI-planned drives. These December 2025 maneuvers along Jezero Crater's rim showcase advanced AI analyzing terrain and identifying hazards, significantly reducing human planning time. This marks a pivotal shift, promising more efficient and responsive deep-space exploration as missions venture further from Earth.
