India To Launch Vehicle-To-Vehicle Technology: How The System Works The technology is expected to be particularly effective in preventing accidents involving parked vehicles and fast-moving traffic from behind. Officials believe V2V technology will play a crucial role in reducing road accidents (Representational) The Government of India is preparing to roll out Vehicle-to-Vehicle (V2V) communication technology by end of 2026. This system will allow vehicles to communicate directly with each other without the need for a network. The initiative aims to strengthen road safety and reduce accidents across the country. The technology is expected to be particularly effective in preventing accidents involving parked vehicles and fast-moving traffic from behind. It will also help avoid large-scale pileups during dense fog, a recurring issue during the winter season. Through this system, vehicles will exchange signals and send alerts to drivers when another vehicle comes dangerously close. Union...

Bacterial Quorum Sensing

  Bacterial Quorum Sensing  Bacterial quorum sensing (QS) is a cell-to-cell communication mechanism that allows bacteria to coordinate collective behaviors based on population density. It relies on the production, release, and detection of small signaling molecules called autoinducers. As bacterial numbers increase, the concentration of these signaling molecules rises, and once a threshold level is reached, it triggers synchronized changes in gene expression across the entire bacterial community. Through quorum sensing, bacteria regulate critical physiological and pathogenic processes such as biofilm formation, virulence factor production, antibiotic resistance, bioluminescence, and motility. Both Gram-negative and Gram-positive bacteria use QS, although they employ different types of signaling molecules and receptor systems. This coordinated response enables bacteria to behave like a multicellular organism, optimizing survival and adaptability in changing environments. In mod...

Artificial Intelligence (AI) and Machine Learning (ML)

Artificial Intelligence (AI) and Machine Learning (ML) refer to a broad set of computational techniques that enable machines to perform tasks that typically require human intelligence, such as learning, reasoning, perception, decision-making, and language understanding. Artificial Intelligence is the overarching field focused on building systems that can simulate intelligent behavior. These systems are designed to analyze data, recognize patterns, adapt to new information, and act autonomously or semi-autonomously. AI encompasses areas such as natural language processing, computer vision, robotics, expert systems, and intelligent decision support. Machine Learning is a core subset of AI that emphasizes data-driven learning. Instead of being explicitly programmed with fixed rules, ML algorithms learn from historical data to identify patterns and make predictions or decisions. Common ML approaches include supervised learning, unsupervised learning, semi-supervised learning, and reinfo...
