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 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."

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.
