The concept of joules, named after Victorian-era physicist James Prescott Joule, has evolved significantly over time. From a simple unit to describe the effort required to pick an apple off the floor, it has grown to encompass larger units such as kilojoules, megajoules, gigajoules, terajoules, petajoules, exajoules, and now zettajoules. However, humanity's increasing energy consumption and its impact on the planet's energy balance have far outpaced our understanding and management of these growing energy levels.

The recent developments in the Iran-US conflict have sparked concerns about the potential for a prolonged and devastating war. Iranian barrages have targeted Israel, Gulf Arab states, and northern Iraq, while Israeli and US warplanes have struck across Iran. The US has considered deploying troops on the ground, further escalating tensions.British Prime Minister Sir Keir Starmer has warned that the conflict may endure, and the economic risks are already crystallizing. Business activity growth in Britain has slowed, manufacturers' input costs have seen their sharpest rise since 1992, and home loans are becoming dearer as the war feeds into energy and inflation fears.The UK government is drawing up contingency plans, such as lowering speed limits to cut fuel use. However, Chancellor Rachel Reeves has ruled out universal household support for any 'Trumpflation' and insists help will remain within her 'iron-clad' fiscal rules. This approach has raised concerns about the government's ability to mitigate the economic impact of the conflict.The conflict has significant implications for global energy markets. Disruptions to oil and gas flows could lead to a structural shift in global energy use, with Europe potentially accelerating its green energy transition and Asia opting for increased coal use. The UK's clean energy transition may be impacted, with higher costs and disrupted supply posing challenges.In conclusion, the Iran-US conflict poses significant risks to global economic stability and energy markets. The UK government must navigate these challenges carefully, balancing the need for economic support with the imperative of maintaining fiscal discipline.

The World Snooker Championship will continue to be held at the iconic Crucible Theatre in Sheffield for at least the next two decades. A long-term agreement between the World Snooker Tour and Sheffield city council ensures the tournament's future at its spiritual home.The Crucible, with its 980-seat capacity, has been the venue for the championship since 1977. Despite speculation about its future, the World Snooker Tour has committed to keeping the event in Sheffield until 2045, with an option to extend until 2050.During this period, the Crucible will undergo a significant revamp, adding 500 seats to the theatre. The championship will temporarily relocate to an alternative UK venue for one year during the redevelopment, but will return to the Crucible.Barry Hearn, president of Matchroom, expressed his delight at the agreement, stating, "For over 50 years I have been promoting sport all over the world but no venue on this planet means more to me than the Crucible." He added, "I am so happy that after a long period of meetings and discussions we have finally agreed a deal to stage the world championship at its historic home – the Crucible."

Sri Lanka's government has rejected a request from the United States to land two combat aircraft at Mattala Rajapaksa International Airport in southern Sri Lanka from March 4 to 8. The request was made on February 26, just before the US and Israel launched their military offensive against Iran.President Anura Kumara Dissanayake told Sri Lanka's parliament that the US wanted to bring two warplanes armed with eight antiship missiles from a base in Djibouti. The government turned down the request to maintain Sri Lanka's neutrality in the conflict.The decision comes amid escalating tensions in the Middle East, with Iranian missile and drone attacks sending energy prices soaring and fuelling fears of a widening conflict. The US-Israeli war on Iran has sparked widespread concern globally, with many countries refusing to get directly involved while calling for urgent de-escalation.Sri Lanka's president also cited his country's neutrality in denying the US request, saying that had they accepted the US request, they would have had to do the same for Iran, which had also made a request for three naval vessels to make a goodwill visit to Sri Lanka on the same day.In recent weeks, Sri Lanka's navy rescued 32 Iranian crew off IRIS Dena after it was torpedoed by a US submarine off the country's coast, killing at least 84 people. Days later, Sri Lanka evacuated more than 200 crew members from a second Iranian vessel, IRIS Bushehr, after the ship requested assistance from Colombo.

Jeffrey Epstein, the late financier and convicted sex offender, urged Canadian-American media and real estate mogul Mortimer Zuckerman to give up control of his financial affairs. Epstein cited Zuckerman's "potentially dangerous" cognitive impairment as the reason for his concern.In an email from October 2015, Epstein suggested that Zuckerman enter a guardianship or conservatorship for his own protection. He expressed concern for Zuckerman's "financial, emotional, physical, and psychological safety", stating that his friends, including himself, were worried about the mogul's well-being.Epstein proposed that Zuckerman grant authority to manage his affairs to Terje Rod-Larsen, a Norwegian diplomat, Zuckerman's nephews, and "anyone else you trust." He emphasized that Zuckerman's "remarkable abilities" were no longer sufficient to protect him.Zuckerman, the owner and publisher of US News & World Report, appeared to take Epstein's advice seriously, thanking him for his "thoughtfulness and friendship" and seeking recommendations for a lawyer with experience in such matters.Epstein also discussed Zuckerman's health with his nephew, Eric Gertler, advising him to oversee the sale of Zuckerman's stocks, art collection, helicopter, and plane. It is unclear if Zuckerman followed Epstein's advice.Zuckerman announced his step down as chairman of Boston Properties about six months after his correspondence with Epstein, but did not cite any health concerns at the time.

At least two people have been killed in a tragic incident involving an Air Canada Express flight that struck a ground vehicle while landing at New York's LaGuardia Airport. The accident occurred on Sunday night, and the airport has been closed since then, with flights diverted to other airports. The aircraft, operated by Jazz Aviation, a regional partner of Air Canada, collided with a firefighting truck on Runway 4 at approximately 11:40 pm on Sunday (03:40 GMT on Monday). The vehicle was driving to respond to a separate incident. According to the Port Authority, 32 of the 41 injured individuals had been released by Monday, while nine remained hospitalized with serious injuries. The passengers and crew members on board Flight AC8646, which departed from Montreal, included 76 people, four of whom were crew members. The CRJ-900 aircraft struck the vehicle at a relatively low speed of 39 kilometers per hour (24 miles per hour). Emergency response protocols were immediately activated, and the US Federal Aviation Administration (FAA) issued a ground stop for all departures to LaGuardia. The National Transportation Safety Board has dispatched a 'go team' to investigate the collision. The incident has caused significant disruptions, with arriving planes being diverted to other airports or returning to their point of origin. New York's Emergency Management has warned of potential cancellations, road closures, traffic delays, and emergency personnel presence near the airport. LaGuardia Airport, which served 33.5 million passengers in 2024, has been experiencing flight disruptions due to poor weather and staffing impacts from a federal funding lapse.

Six decades ago, pioneering oceanographer and conservationist Sylvia Earle made a remarkable discovery while diving off Chile’s oceanic islands. She found the remains of a baby fur seal, a species endemic to the Juan Fernández archipelago that was believed to have been hunted to extinction in the 19th century. This discovery gave Earle hope that a small population might still exist, and indeed, a year later, a colony of 20 endemic fur seals was confirmed on Robinson Crusoe Island.Today, after decades of conservation efforts, the fur seal population has made an extraordinary recovery. An estimated 200,000 fur seals now inhabit the waters around the islands, returning them to their previous role as key members of the ecosystem. Earle, now 90, who returned to the island to dive in December 2025, described the archipelago as a critical 'Hope Spot' for marine protection.In a significant conservation victory, outgoing Chilean President Gabriel Boric recently signed an agreement to extend protection of 337,000 sq km of waters around Juan Fernández and the nearby Nazca-Desventuradas marine park. Once implemented, this 'no take' zone will extend to almost 1 million sq km, making it the third-largest such marine protected zone in the world. By doing so, Chile would protect more than 50% of its waters, placing it in a rare category alongside countries such as Panama and French Polynesia.The protection prohibits all fishing activities except within 12km of the coast, allowing the community of approximately 1,000 lobster fishers to continue their traditional livelihood. Chile is now out in front globally in ocean protection efforts, according to Earle, as most countries have been slower to commit to such extensive marine conservation.The initiative was driven by the Juan Fernández islanders and conservation NGOs who have advocated for decades to protect the unique ecosystem. The fishers, who witnessed the damage caused by industrial fishing of the orange roughy in the 1990s and 2000s, have practiced stewardship of their fishery. A survey showed 98% of residents supported extended protections, leading the fishers to present a proposal directly to the president.Julio Chamorro Solís, a lobster fisher and president of the local fishing organization, emphasized the importance of the unique ecosystem: 'We know the level of endemism we have and how fragile this ecosystem is. There's a biological treasure here.'However, the future of this expanded protection remains uncertain. The new Chilean government, led by President-elect José Antonio Kast, is currently reviewing environmental laws established by the previous administration. While the Chilean ministry of the environment has stated its intention is not to eliminate protections, conservationists and islanders await confirmation that the marine park extension will proceed as planned.This initiative aligns with global commitments to protect 30% of the world's oceans by 2030, a goal reinforced by the recent implementation of the high seas treaty. The expansion of Chile's marine protected areas represents a significant step toward achieving this ambitious target while safeguarding one of the planet's unique marine ecosystems.
