This expansion is asymmetric, occurring earlier in spring in regions like western Europe and northwestern India, and later into autumn in areas such as the western US and eastern China. Researchers highlight the challenges this poses for human acclimatisation and community preparedness, as existing infrastructure like cooling centres are built around historical summer calendars.
Zoho co-founder Sridhar Vembu argues that predictions of AI's catastrophic outcomes are overstated and a global pause in AI development is improbable. He urges India to adopt an independent AI strategy, focusing on extensive foundational R&D across sectors, while remaining wary of market monopolisation attempts by major tech players. Vembu also highlights concerns about AI's impact on human judgment, skill development, and job markets, particularly for junior professionals.
Scientists at IIT Mandi have identified the cellular signature of anaesthesia in plants, a discovery that challenges conventional understanding of consciousness. Their research shows plants respond to anaesthetics in a synchronised manner, reorganising cellular nuclei despite lacking a brain or nervous system, suggesting a more sentient nature than previously believed and resonating with ancient Indian philosophical thought.
A global research report by HCLTech indicates that integration has surpassed supply chain constraints as the primary challenge for the semiconductor industry.
