Longevity: can ageing be reversed?

Experts project that treatments to reverse biological age could emerge within five decades, driven by breakthroughs such as epigenetic reprogramming and genetic interventions like those modifying the *DAF2* gene. These scientific advances, supported by studies on dietary restriction and the health benefits of centenarians, are attracting significant capital to develop therapies targeting senescent cells and common drugs like Metformin. The resulting economic imperative aims to reduce the burden of age-related disease while transforming the demographic challenge of an aging population into a trillions-of-dollars opportunity.

What to expect from King Charles III

King Charles III

Upon becoming the world's oldest British monarch and longest-serving heir, Charles III must balance his role as Supreme Governor of the Church of England with the demands of a modern, religiously diverse nation. To ensure the institution's survival, he is strategically reducing the size of the working royal family to address public concerns over cost while navigating internal family tensions and the risk of constitutional crisis arising from his past political advocacy. This transition marks a shift from the universal respect commanded by his mother toward a more polarizing leadership style that relies on rapid adaptation to maintain the monarchy's public relevance.

How does raising interest rates control inflation?

Central banks globally utilize interest rate hikes to curb inflation by increasing borrowing costs, yet this strategy faces a historic challenge where reducing inflation above 5% without triggering a recession has not occurred in over 70 years. While the mechanism effectively dampens spending through variable mortgages and business investment, fixed-rate markets and implementation lags of up to two years create complex economic disparities and risks of over-correction. Ultimately, policymakers aim to anchor expectations at a 2% target, balancing the immediate pain of higher costs against the severe historical precedent of the 1981 recession that required rates to reach 19%.

Is higher inflation cause for concern?

Global economies are grappling with unexpected inflationary surges driven by supply chain disruptions, massive stimulus spending, and emerging market crop shortages, with rates soaring far above the 2% targets set by major central banks. While wealthy nations initially hesitated to raise interest rates, emerging markets like Brazil, Russia, and Mexico have aggressively tightened monetary policy to preserve credibility and anchor public expectations. Policymakers now face the critical challenge of distinguishing between temporary price spikes and persistent inflation to prevent long-term economic damage and eroded living standards.

How will covid-19 change travel?

Sonia, Nacho Rodriguez, Michael O'leary, Simon Wright

The pandemic has fundamentally reshaped global tourism by accelerating remote work trends that favor "bleisure" travel and alternative accommodations while simultaneously causing a historic collapse in international air travel volumes. In response to these disruptions, airlines face grim long-haul recovery prospects due to vanishing corporate demand, prompting a strategic industry pivot toward sustainable models and digital health verification tools like vaccine passports. Regional governments and destinations are now actively restructuring their economies to attract knowledge workers and disperse mass tourism crowds, prioritizing long-term ecological balance over a rapid return to pre-2019 visitor numbers.

Mining the deep sea: the true cost to the planet

Kerry Howell, Matt Upton, Claire

As global demand for green technology minerals outstrips land-based reserves, deep-sea mining operations utilizing vehicles like the ROV Isis target vast deposits of critical metals in the Clarion-Clipperton Zone and hydrothermal vents. While proponents cite Japan's recent successful extraction and the urgency of replacing ethically problematic land mining, scientists warn that the unregulated exploration licenses issued by the International Seabed Authority threaten to destroy unique species and disrupt essential carbon-sequestering ecosystems. The International Seabed Authority is currently evaluating applications that could launch large-scale industrial extraction, prompting urgent calls to weigh these economic gains against the irreversible loss of unknown biodiversity and ecosystem services.

Public Debt: how much is too much?

Ryan Avent

Between April and June 2020, the United States borrowed a record $3 trillion while the global economy saw public debt surge by an estimated $300 billion due to pandemic-related spending. Historical precedents and favorable conditions, such as low interest rates, have traditionally allowed nations to sustain high debt levels, though experts warn that a potential rise in rates could threaten financial stability. Consequently, economists maintain that despite these risks, continued deficit spending remains essential to prevent lasting damage to the global recovery.

Election 2020: what a Biden victory could mean for America

Biden

The Economist forecast predicts a high probability of Joe Biden winning the presidential election by leveraging leads in traditional battleground states and previously Republican strongholds despite his advanced age. Ideologically positioned as a moderate center-left candidate, Biden plans to pursue progressive domestic policies through a government-run public option, a $2 trillion climate plan, and immediate executive actions to reverse Trump-era rollbacks. To implement this agenda, his broad electoral appeal is expected to generate significant coattails that could help Democrats flip the Senate, though the filibuster remains a primary legislative obstacle.

How scientists calculate climate change

Vilhelm Bjerknes, Oliver Morton

Building on Wilhelm Bjerknes' 19th-century formulas, modern atmospheric computers now operate 25 trillion times faster than early models to simulate global climate behavior through complex grid systems. Although technical limitations regarding small-scale cloud dynamics create divergent warming projections, historical data confirms these tools accurately forecast observed trends when paired with economic scenarios that link human policy to temperature outcomes. Ultimately, while these models cannot predict human decisions, they remain the essential instrument for quantifying carbon dioxide's impact and guiding the stringent emission reductions necessary to meet Paris Agreement targets.

Mangroves: how they help the ocean

Lillian, Mark Huxham

Global mangrove ecosystems face imminent collapse due to industrial expansion, prompting the launch of Mikoko Pomoja in Kenya's Ghazi Bay as the world's first community-led project funded by carbon credits. This initiative has successfully generated over $60,000 for local communities while sequestering significant carbon in sediment, effectively incentivizing conservation over resource extraction. Although experts caution that such offsets cannot replace broader policy reforms, the model is gaining traction as a replicable strategy for marine protection and economic stability across the region.

How to get migration right

Anna, Madeleine Sumption

This analysis contrasts Australia's points-based immigration system, which facilitated a 22-fold economic expansion alongside a 33% foreign-born population, with the United States' reliance on family reunification and rigid caps. While public discourse often polarizes around economic threats and cultural disruption, the Australian model demonstrates that strict border control combined with selective skilled migration can sustain high intake levels without recession. The discussion concludes by proposing policy mechanisms like earmarked migrant taxes or welfare restrictions to alleviate voter apprehension and prove the net economic benefit of unrestricted labor mobility.

Why is chicken so cheap? | The Economist

David Speller

Driven by the 1940s "Chicken of Tomorrow" competition, the global poultry industry now sustains a population of 23 billion birds through intensive genetic breeding that compresses broiler lifespans to 38 days. Consultant David Speller exemplifies this scale by managing millions of genetically uniform chickens with automated environmental controls, prioritizing rapid growth over natural maturity to meet high-volume, low-cost consumer demand. While organic and free-range systems offer significantly longer lifespans and better welfare conditions, their higher production costs and lower turnover rates keep them marginal compared to the dominant industrial model.
