A new study published in Current Biology explains the cellular adaptations that enable mangrove species to tolerate extreme salt stress, offering insights for developing salt-tolerant crops in the future.
Key Highlights of the Study
Key cellular traits (not stomata-based): Mangroves do not rely on smaller or more numerous stomata to increase photosynthesis.
Instead, they exhibit: unusually small leaf epidermal pavement cells and thicker cell walls, which together give them more mechanical strength to tolerate low osmotic potentials.
India designated Siliserh Lake and Kopra Jalashay as its 95th and 96th Ramsar Sites, increasing the country’s total to 96, up from 26 in 2014.
What are the Wetlands?
The Ramsar Convention’s definition for wetlands includes:
“areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres”.
Human-made wetlands: Fish and shrimp ponds, farm ponds, irrigated agricultural land, salt pans, reservoirs, gravel pits, sewage farms and canals.
The Supreme Court issued systemic directions to strengthen enforcement of anti-dowry laws.
SC observed that dowry is a deep-rooted social evil cutting across communities and requires institutional accountability, not merely penal provisions.
SC Directions
Judicial Monitoring: High Courts must monitor pending cases under IPC Sections 304-B (dowry death) and 498-A (cruelty) for expeditious disposal, with the judgment circulated for compliance review.
Administrative Enforcement: States must appoint and resource Dowry Prohibition Officers (DPOs) under Section 9 of the Dowry Prohibition Act, 1961, disseminating their contact details widely.
Capacity Building & Sensitisation: Police and judicial officers require periodic training on case sensitivity, distinguishing genuine claims from frivolous ones, while district administrations and Legal Services Authorities run grassroots awareness campaigns.

करंट बायोलॉजी में प्रकाशित एक नए अध्ययन ने उन कोशिकीय अनुकूलनों की व्याख्या की है जो मैंग्रोव प्रजातियों को अत्यधिक लवणीय तनाव सहन करने में सक्षम बनाते हैं।
विशेषताएँ
मुख्य कोशिकीय लक्षण (स्टोमाटा-आधारित नहीं): मैंग्रोव प्रकाश संश्लेषण बढ़ाने के लिए छोटे या अधिक संख्या वाले स्टोमाटा पर निर्भर नहीं होते।
नमक बहिष्करण : कुछ मैंग्रोव में मोमी जड़ परतें होती हैं जो जल पौधे में प्रवेश करने से पहले नमक को छान देती हैं।
