A novel study published in Science Translational Medicine has identified envelope dimer epitope (EDE)-like antibodies as key to developing broad, cross-serotype immunity against dengue. This finding is significant because initial dengue infection paradoxically increases the risk of severe disease upon secondary infection with a different serotype, a phenomenon called antibody-dependent enhancement. The study, conducted in the Philippines, found high prevalence of EDE-like antibodies in individuals with secondary immunity, strongly correlating with protection against symptomatic and severe dengue across multiple serotypes. This research offers a pathway to developing more effective dengue vaccines that specifically target the elicitation of EDE-like antibodies.

Haemophilia, a rare inherited bleeding disorder, causes excessive and spontaneous internal bleeding, leading to chronic disability and life-threatening situations. India faces a significant challenge with only 20% of estimated cases diagnosed due to lack of awareness and facilities, leaving many vulnerable. Untreated bleeds reduce life expectancy and cause socio-economic burdens. Prophylaxis, or regular replacement therapy of deficient clotting factors, has emerged as the 'gold standard' treatment. Unlike on-demand therapy, prophylaxis proactively prevents bleeds, ensuring good joint health, maintaining mobility, enhancing quality of life, and reducing healthcare burdens. Increased awareness and access to prophylaxis are critical to ending under-diagnosis and preventable disabilities in India.

Biochar, a carbon-rich charcoal produced from agricultural residue and organic waste, is poised to play a crucial role in India's carbon market, set to launch in 2026. India generates vast amounts of waste, much of which is openly burnt, contributing to pollution. Utilizing 30-50% of this surplus waste could yield 15-26 million tonnes of biochar annually, removing 0.1 gigatonnes of CO2-equivalent. Biochar acts as a stable carbon sink for 100-1,000 years, improving soil water retention, reducing nitrous oxide emissions, and enhancing soil organic carbon. It also has potential in construction as a low-carbon building material and in wastewater treatment. Despite its potential, biochar faces hurdles like lack of standardized markets, investor confidence, and insufficient policy support, requiring R&D and integration into climate strategies for large-scale adoption.
- Biochar, produced from agricultural and organic waste, is a promising CO2 removal technology for India's upcoming carbon market.
- India's large waste generation offers significant potential for biochar production, capable of removing substantial CO2-equivalent annually.

Union Minister Jitendra Singh stated that 'riverine inputs' and abandoned, lost, and discarded fishing gear (ALDFG) are the primary sources of microplastic pollution along India's coasts. Field surveys by the National Centre for Coastal Research (NCCR) under the Ministry of Earth Sciences (MoES) confirmed this, covering transects along both east and west coasts. Microplastics, tiny plastic particles ranging from 1 micrometre to 5 millimetres, are a major concern due to their increasing links to tumors and toxicity to marine and aquatic life. The Food Safety and Standards Authority of India (FSSAI) has commissioned a project to assess microplastic contamination in food products.
- Riverine inputs and abandoned, lost, and discarded fishing gear (ALDFG) are identified as major sources of microplastic pollution on Indian coasts.

India's rapid electrification, driven by EV adoption and renewable energy, is projected to significantly increase lithium battery demand, posing environmental risks if waste is not managed properly. The Battery Waste Management Rules (BWMR) 2022 mandate Extended Producer Responsibility (EPR), compelling producers to fund recycling. However, a key challenge is the low EPR floor price, which makes legitimate recycling economically unviable, leading to informal and fraudulent practices. This undermines India's circular economy goals and could result in significant environmental degradation and foreign exchange losses. The article calls for fair EPR floor pricing, robust enforcement, and integration of informal recyclers to transform waste into a catalyst for green growth.
- India's growing demand for lithium batteries, driven by EVs and renewable energy, necessitates robust battery waste management.
- The Battery Waste Management Rules (BWMR) 2022 introduce Extended Producer Responsibility (EPR) to fund battery collection and recycling.
