Presidential immunity is the concept that sitting presidents of the United States have civil or criminal immunity for their official acts. Neither civil nor criminal immunity is explicitly granted in the Constitution or any federal statute. However, the Supreme Court of the United States ruled in Trump v. United States (2024) that all presidents have absolute criminal immunity for official acts under core constitutional powers, presumptive immunity for other official acts. The court held that there is no immunity for unofficial acts. The court made this decision after former President Trump claimed immunity from prosecution for actions performed within the perimeter of his responsibilities as president.

Previously, the Supreme Court had found in Nixon v. Fitzgerald (1982) that the president has absolute immunity from civil damages actions regarding conduct within the "outer perimeter" of their duties. However, in Clinton v. Jones (1997), the court ruled against temporary immunity for sitting presidents from suits arising from pre-presidency conduct. Some scholars suggested an immunity from arrest and criminal prosecution as well, a view which became the practice of the Department of Justice under a pair of memoranda (1973 and 2000) from the Office of Legal Counsel. Presidents Richard Nixon, Bill Clinton, and Donald Trump were criminally investigated while in office, but none were prosecuted while still in office.

The Sinclair C5 is a small one-person battery electric velomobile, technically an "electrically assisted pedal cycle". It was the culmination of Sir Clive Sinclair's long-running interest in electric vehicles. Although widely described as an "electric car", Sinclair characterised it as a "vehicle, not a car".

Sinclair had become one of the UK's best-known millionaires, and earned a knighthood, on the back of the highly successful Sinclair Research range of home computers in the early 1980s. He hoped to repeat his success in the electric vehicle market, which he saw as ripe for a new approach. The C5 emerged from an earlier project to produce a small electric car called the C1. After a change in the law, prompted by lobbying from bicycle manufacturers, Sinclair developed the C5 as an electrically powered tricycle with a polypropylene body and a chassis designed by Lotus Cars. It was intended to be the first in a series of increasingly ambitious electric vehicles, but the development of the follow-up C10 and C15 models never got further than the drawing board.

On 10 January 1985, the C5 was unveiled at a glitzy launch event but it received a less than enthusiastic reception from the British media. Its sales prospects were blighted by poor reviews and safety concerns expressed by consumer and motoring organisations. The vehicle's limitations – a short range, a maximum speed of only 15 miles per hour (24 km/h), a battery that ran down quickly and a lack of weatherproofing – made it impractical for most people's needs. It was marketed as an alternative to cars and bicycles, but ended up appealing to neither group of owners, and it was not available in shops until several months after its launch. Within three months of the launch, production had been slashed by 90%. Sales never picked up despite Sinclair's optimistic forecasts and production ceased entirely by August 1985. Out of 14,000 C5s made, only 5,000 were sold before its manufacturer, Sinclair Vehicles, went into receivership.

The C5 became known as "one of the great marketing bombs of postwar British industry" and a "notorious ... example of failure". Despite its commercial failure, the C5 went on to become a cult item for collectors. Thousands of unsold C5s were purchased by investors and sold for hugely inflated prices – as much as £5,000, compared to the original retail value of £399. Enthusiasts have established owners' clubs and some have modified their vehicles substantially, adding monster wheels, jet engines, and high-powered electric motors to propel their C5s at speeds of up to 150 miles per hour (240 km/h).

A Kavanaugh stop is a law enforcement practice in the United States in which federal agents can stop and briefly detain a person based on their perceived ethnicity, spoken language, or occupation in consideration with other factors. Kavanaugh stops originated in a September 2025 Supreme Court concurrence by Justice Brett Kavanaugh in Noem v. Vasquez Perdomo.

🔗 Climate change 🔗 Geography

The Third Pole, also known as the Hindu Kush-Karakoram-Himalayan system (HKKH), is a mountainous region located in the west and south of the Tibetan Plateau. Part of High-Mountain Asia, it spreads over an area of more than 4.2 million square kilometres (1.6 million square miles) across nine countries, i.e. Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal, Pakistan and Tajikistan, bordering ten countries. The area is nicknamed the "Third Pole" because its mountain glaciers and snowfields store more frozen water than anywhere else in the world after the Arctic and Antarctic polar caps. With the world's loftiest mountains, comprising all 14 peaks above 8,000 metres (26,000 ft), it is the source of 10 major rivers and forms a global ecological buffer.

The Third Pole area is rich with natural resources and consists of all or some of four global biodiversity hotspots. The mountain resources administer a wide range of ecosystem benefits and are the base for the drinking water, food production and livelihoods of the 220 million inhabitants of the region, as well as indirectly to the 1.5 billion people — one sixth of the world's population — living in the downstream river basins. Billions of people benefit from the food and energy produced in these river basins whose headwaters rely on meltwaters and precipitations that run off these mountains.

🔗 India 🔗 Transport 🔗 Travel and Tourism

The bus service from London, England to Calcutta, India (now Kolkata) was considered to be the longest bus route in the world. The bus service, which started in 1957, was routed to India via Belgium, Yugoslavia and North Western India. This route is also known as the Hippie Route. According to reports, it took about 50 days for the bus to reach Calcutta from London. The voyage was over 10,000 miles (16,000 km) one way and 20,300 miles (32,700 km) for the round trip. It was in service until 1976. The cost of the trip one-way was £85 in 1957 and £145 in 1973. This amount included food, travel and accommodation.

A graphite bomb is intended to be a non-lethal weapon used to disable an electrical grid. The bomb works by spreading a dense cloud of extremely fine, chemically treated carbon filaments over air-insulated high voltage installations like transformers and power lines, causing short-circuits and subsequent disruption of the electricity supply in an area, a region or even an entire small country. The weapon is sometimes referred to as blackout bomb or as soft bomb because its direct effects are largely confined to the targeted electrical power facility, with minimal risk of immediate collateral damage. However, since water supply systems and sewage treatment systems depend on electricity, widespread outbreaks of cholera and other waterborne diseases, causing large numbers of civilian deaths, have in the past been the direct consequence of this bomb's use.

🔗 Disability

Audio induction loop systems, also called audio-frequency induction loops (AFILs) or hearing loops, are an assistive listening technology for individuals with reduced ranges of hearing.

A hearing loop consists of one or more physical loops of cable which are placed around a designated area, usually a room or a building. The cable generates an electromagnetic field throughout the looped space which can be picked up by a telecoil-equipped hearing aid, a cochlear implant (CI) processor, or a specialized hand-held hearing loop receiver for individuals without telecoil-compatible hearing aids.

The loops carry baseband audio-frequency currents; no carrier signal is used. The benefit is that it allows the sound source of interest – whether a musical performance or a ticket taker's side of the conversation – to be transmitted to the hearing-impaired listener clearly and free of other distracting noise in the environment. Typical installation sites include concert halls, ticket kiosks, high-traffic public buildings (for PA announcements), auditoriums, places of worship, courtrooms, meeting rooms, and homes.

In the United Kingdom, as an aid for disability, their provision, where reasonably possible, is required by the Equality Act 2010 and previously by the Disability Discrimination Act 1995, and they are available in "the back seats of all London taxis, which have a little microphone embedded in the dashboard in front of the driver; at 18,000 post offices in the U.K.; at most churches and cathedrals", according to Prof. David G. Myers.

In the United States, an alternative technology using FM transmission to "neck loop" receivers was more widely adopted due to economic advantages. In comparison, hearing loop systems require a greater initial investment by the facility operator, but offer greater convenience and avoid the social stigma and hygienic concerns entailed by the FM system's paraphernalia for those who have hearing aids.

Another alternative system, used primarily in theatres, uses invisible infrared radiation; compatible headsets can pick up the modulated infrared energy to reproduce sound.

A road diet (also called a lane reduction, road rechannelization or road conversion) is a technique in transportation planning whereby the number and/or the width of travel lanes of the road is reduced, often to achieve a reduction in crash rates.

In geography, a pole of inaccessibility is the farthest (or the most difficult to reach) location in a given landmass, sea, or other topographical feature, starting from a given boundary, relative to a given criterion. A geographical criterion of inaccessibility marks a location that is the most challenging to reach according to that criterion. Often it refers to the most distant point from the coastline, implying the farthest point into a landmass from the shore, or the farthest point into a body of water from the shore. In these cases, a pole of inaccessibility is the center of a maximally large circle that can be drawn within an area of interest only touching but not crossing a coastline. Where a coast is imprecisely defined, the pole will be similarly imprecise.
