Meta owns Facebook, Instagram and WhatsApp, and AI companies need huge amounts of online content to train their models. Fights over who may collect that data are part of a wider global debate on AI, copyright and publisher revenue.

Concerns about AI and privacy often centre on whether personal data used in training can be pulled back out later by clever questioning. Anonymising records is one common safeguard, but it may not be a complete shield.

Context: AI model makers have mostly sold software, while IT services firms have long set up that software inside big companies. Now both want the same client budgets, so the AI makers are moving closer to the customer.

Context: AI data centres need huge amounts of electricity to run chatbots and cloud services, and many are being built worldwide. Burning gas releases carbon, so the power source matters for climate targets.

Anthropic is one of several leading AI labs racing to build more capable models. Alignment means making AI systems act in line with human goals and values, and it is a central worry as models grow stronger.

Context: mRNA vaccines train the immune system to recognise a target, and they drew wide attention during the Covid-19 pandemic. Personalised cancer vaccines are a growing research area where treatment is tailored to each patient's tumour.

Context: AI-ready laptops include chips built to run some AI tasks directly on the device, rather than only in the cloud. Makers say this can help with privacy and speed, and it is part of a wider shift in how PCs are sold.

Context: Companies often borrow through bonds to fund large projects, and AI data centres and chips are among the costliest spending today. Voluntary buyouts are offers to leave with payment, a common cost-cutting step at large tech firms.

Context: Rules like these track money moving in and out of India, so the central bank can monitor foreign exchange flows. Services exports include work such as software, consulting or freelance projects sold to buyers abroad.

Context: Indian law requires employers to have a written harassment prevention policy and a complaint committee. Harassment at work can also happen during travel, client meetings or after-hours events, which is why policies often cover more than the office.

Context: PM Surya Ghar is a central government scheme that helps households install rooftop solar panels, and it is a major part of India's push for cleaner energy and lower household power bills.

Context: Implants such as joint replacements and stents stay inside the body for years, so the metal used must be strong and safe. Researchers usually test new alloys carefully for years before they reach patients.

Context: Parliament passed four labour codes in 2019 and 2020, merging many older labour laws into them, and trade unions have opposed them since. Jantar Mantar is the Delhi site where groups often hold large protests.

Context: Many small fishing boats on India's west coast have long run on kerosene, a cheap fuel, so price changes hit them quickly. Fishermen have few easy alternatives, and their income depends on daily catches.

Context: Privacy displays narrow the viewing angle so people beside you find the screen hard to read, which helps on crowded trains and in open offices. The Galaxy S series is Samsung's flagship phone line, and the Ultra is its largest and most premium model.

Context: Grok is the AI chatbot built by Elon Musk's xAI and offered through the X platform. Running advanced AI models takes heavy computing power, which is why many chatbot makers limit how much people can use them.

Context: Bangladesh's garment industry is one of the world's largest clothing exporters and employs millions of workers, many of them women. Pay has been a recurring source of unrest in the sector, so disputes there can affect global clothing supply.

Bihar, in eastern India, faces yearly floods during the monsoon, when rivers like the Kosi and Gandak carry heavy loads of silt. Flood plans often aim to reduce damage while also finding useful ways to handle the material dug out of rivers.

Context: Solar and wind power depend on sunshine and wind, so batteries help store extra power for evening use. Many Indian states are adding storage to their clean energy plans for the same reason.

Context: Worms like C. elegans are used in labs because their genes are simple and easy to study, and many of them match human genes. Polycystin-2 is a protein linked to a form of kidney disease that causes fluid-filled cysts.

Context: Milkweed is a flowering plant that supports pollinators and is a food source for monarch butterflies. Honey bees and other pollinators help crops and wild plants produce fruit and seeds, so changes in their visits matter for ecosystems.

Context: Stubble burning is when farmers burn leftover crop stalks after harvest, mainly in Punjab and Haryana, and the smoke drifts toward Delhi each autumn and winter. States have long argued over who should carry the blame and the cost of fixing it.

Context: The monsoon brings most of India's rain, and a weak season reduces water for both farming and reservoirs. Food inflation is the steady rise in the prices of everyday items like grains, vegetables and pulses.

Context: The IMD is India's weather agency, and its alerts guide district officials on whether schools should close. Northeast monsoon rain often affects parts of the south and east in October and November.

Context: Tiger reserves are protected forests where tigers and other wildlife are kept safe from heavy human activity. Illegal construction in such areas has been a long-running concern, and courts often step in when local rules are broken.

Critical infrastructure means power grids, water, transport and banking systems that people rely on every day. Governments are increasingly worried that AI tools could make hacking faster and cheaper, so security teams are racing to keep up.

Context: Languishing is a term psychologists use for low well-being, feeling flat and without purpose, which is different from a formal mental illness. Large surveys like this help track how wellbeing changes across age groups.

Context: Dibru-Saikhowa is a protected wildlife area in Assam known for its birds and wild animals, so drilling beneath it raises environmental questions. Approvals for such projects usually need clearance from environment and forest authorities.

Context: The Milky Way is the galaxy that holds our Sun and the solar system. Galaxies often merge and absorb neighbours over billions of years, and astronomers read the leftover stars to piece together that history.

The Southwest US is largely arid, so dry ground struggles to absorb sudden heavy rain. US midterm elections fall on the Tuesday after the first Monday of November, so floods can disrupt voting plans.

Context: Bengaluru has grown fast and depends on water pumped from the Cauvery river and from underground aquifers, so any gap in supply is felt quickly by households.

Context: Long-term capital gains tax is charged on profits from selling assets held for a long time, such as shares. Foreign investors put money into Indian markets, so changes to this tax can affect how much they invest.

Context: GRAP is a set of graded steps that tighten as pollution rises, and Stage 2 limits activities such as construction and dust-raising work. Winter smog in north India is worsened by crop residue burning and Diwali firecrackers.

Context: Bengaluru is building several metro lines to ease heavy road traffic in the city. Namma Metro is the local name for the metro system that serves the city, and new stretches are opened in phases as construction finishes.

Context: Sugarcane is sold to sugar factories, so farmers depend on fair prices being agreed for their harvest. Drought stresses the crop and makes pricing disputes more urgent for growers.

Viksit Bharat is the government's long-term goal of making India a developed nation by 2047. Banks are central to lending for homes, businesses and farms, so their strength shapes the wider economy.

Context: Mumbai's main airport is busy and short of room, so the newer airport in Navi Mumbai is meant to take some of the load. Foreign carriers that fly to Mumbai are expected to adjust their routes.

Context: Dhanteras falls before Diwali and is traditionally seen as an auspicious day to buy gold or silver. Precious metal prices move daily with global markets, so timing a purchase is hard to predict.
