Do plants feel pain? | The Economist
Biologists Michael Levin and other experts presented evidence that non-neural mechanisms like bioelectric fields enable information processing in organisms without centralized brains, as demonstrated by planaria worm regeneration and conditioned *Mimosa pudica* responses. The event detailed documented plant capabilities including visual mimicry, auditory toxin release, and the distinction between environmental sentience and human-style consciousness. While debate persists regarding whether immobile flora can perceive pain, the consensus among interviewed scientists suggests that plant intelligence is fundamentally an adaptive problem-solving tool rather than a basis for moral objection to consumption.

How to play chess like a grandmaster | The Economist
This analysis positions chess as a rigorous framework for human cognition, illustrating how expert players balance intuitive pattern recognition with deliberative calculation across the game's three distinct phases. The discussion highlights how modern AI engines, which prioritize probabilistic outcomes over traditional material evaluation, have paradoxically driven human players toward more aggressive and creative styles rather than rendering the game obsolete. Ultimately, the enduring surge in chess popularity despite AI dominance serves as a resilient precedent for human adaptation in an increasingly automated landscape.

Has science finally cracked the secret to invisibility?
Alok Jha, Professor Sir John Pendry, John Pendry
Physics professor John Pendry introduced metamaterials as geometrically engineered structures capable of manipulating light paths to achieve the effects described in his "invisibility cloak" concept. This theoretical framework, initially named by Pendry's wife to aid a 2005 DARPA presentation, faced early skepticism before David Smith's team at Duke University successfully constructed a functional prototype for radar waves. The field has since evolved from resolving debates over negative refraction to experimental recreations of conditions existing near black holes.

Has Mars revealed a new clue about life on its surface?
Dr Katie Stack Morgan, Alok Jha
NASA's Perseverance rover recently identified distinct mineral patterns in Mars' "Chiava Falls" outcrop that the science team voted to classify as potential biosignatures, marking the closest any agency has come to detecting ancient life. While these findings strongly suggest a biological origin due to their specific chemical arrangement, the rover's limitations require the samples to be returned to Earth for definitive analysis. This critical next step relies on the Mars Sample Return program, which currently faces budgetary uncertainty even as scientists describe the discovery as a historic scientific milestone.

How much protein do you really need?
A recent discussion detailed the physiological role of proteins as primary structural materials while analyzing dietary guidelines that range from the World Health Organization's 0.8 grams per kilogram recommendation to sports science suggestions of up to 1.6 grams per kilogram. The presentation highlighted that excessive protein intake above this threshold offers no additional muscle growth benefits and may pose kidney risks, particularly when derived from saturated fats and processed meats. Instead of prioritizing extreme dietary calculations, experts advised combining consistent strength training with enjoyable exercise routines to ensure long-term health and muscle maintenance.

Generative AI: what is it good for?
Alok Jha, Tom Standage, Abhi Burtix, Arjun Romani
Following the 2017 Transformer architecture and the historic 2022 adoption of GPT-3.5, large language models now process unlabeled internet data to excel at tasks ranging from medical licensing exams to code generation. Despite these capabilities, the technology remains a "black box" with complex, opaque weights that lack the transparency required for high-stakes fact-finding or full automation. Consequently, while economists project that generative AI will impact half of the daily tasks for 20% of the U.S. workforce, current deployment is expected to evolve as a human-AI collaborative workflow rather than an immediate replacement of human roles.

Covid-19: more questions about coronavirus, answered
Ed Carr, Alok Jha, Edward Carr
Policymakers and economic analysts are addressing the severe trade-off between strict disease containment and deepening economic contraction, with US Treasury Secretary Steve Mnuchin warning that unemployment could reach 20% without intervention. The event evaluates the likely L-shaped recession trajectory while examining how global aid, healthcare disparities, and the virus's seasonal mutation patterns will shape long-term recovery. Ultimately, the discussion emphasizes the necessity of international cooperation to restore scientific trust and accelerate vaccine development within an 18-to-24-month window despite rising nationalistic trends.
