Artificial intelligence tools are evolving rapidly, but the Grok AI controversy highlights what can go wrong when innovation outpaces responsibility. Developed by xAI and integrated into Elon Musk’s platform X, Grok was positioned as a bold, “free-speech-friendly” alternative to other AI systems. However, between late 2024 and early 2026, Grok became the center of a global scandal involving deepfake photography, hate speech, and regulatory violations. Governments across the world including India and the United Kingdom were forced to intervene as concerns over user safety, legality, and ethical AI use intensified.

Chromium (Cr), a redox-active heavy metal, induces oxidative stress in plants by generating reactive oxygen species (ROS) such as hydrogen peroxide, superoxide anion, and hydroxyl radicals, which reduce plant productivity and yield. This study evaluated the potential of biochar (BC) derived from apricot kernel shells to alleviate Cr toxicity in Brassica juncea. The BC was characterized as amorphous, alkaline (pH 7.84), with a zeta potential of –22.3 mV, and elemental composition of C (60.70%), O (29.58%), H (2.65%), and N (0.77%). FTIR analysis revealed multiple oxygen-containing functional groups, suggesting its capacity to reduce Cr mobility. The alkaline nature and porous structure of the BC further support its immobilization potential. Seeds of B. juncea were germinated in soil treated with 0.5 mM and 0.75 mM Cr, with or without 1% BC (10 g/kg soil). Cr exposure significantly reduced photosynthetic pigments, with total chlorophyll declining by 30.8–49.1% and carotenoids by 25.7–50% compared to control, while pheophytin content increased by 13.9–45.3%. Application of BC improved chlorophyll content and reduced pheophytin accumulation. Secondary metabolites and osmolytes were enhanced under BC and stress treatments, with total phenols increased by up to 45% and total carbohydrates by up to 34%. Growth and germination parameters were also negatively affected by Cr, but BC treatment effectively mitigated these effects, improving root and shoot development. Overall, apricot kernel shell–derived BC alleviated Cr phytotoxicity by reducing metal availability and enhancing plant growth, photosynthetic performance, and metabolic activity. These findings highlight its potential as an eco-friendly and sustainable strategy for mitigating heavy metal stress in plants

India's SMEs are embracing digital tools, but cybersecurity preparedness lags. Cybercriminals are increasingly targeting smaller businesses, exploiting routine processes like invoice fraud. With over 12 lakh UPI fraud cases reported in FY25, the landscape has shifted, making cybersecurity a critical business resilience issue. Regulatory frameworks are now formalizing expectations, emphasizing practical steps over large budgets for enhanced cyber defense.
