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.

This vaccine could stop the next pandemic | The Economist
Advances in immunology over the last 15 years, highlighted by research from Mihaly Netea at Radboud University and a 2024 Stanford study, demonstrate that vaccines like BCG can epigenetically "train" the innate immune system to provide broad-spectrum protection. This emerging approach aims to deploy universal vaccines as a strategic bridge at the onset of pandemics or before flu seasons to maintain societal stability while waiting for highly specific variants to be addressed. Although current findings are limited by species differences, the proposed strategy envisions a complementary model where these broad-acting shots work alongside traditional vaccines to buy critical time against diverse pathogens.

Why pig organ transplants are closer than ever
Emilie Steinmark, Alok Jha, Emily
Faced with a global organ shortage where 90% of candidates die waiting, the medical field has pivoted to genetically engineered pig organs as the primary solution due to their physiological compatibility and scalable breeding. Scientists achieve this by removing pig-specific antigens and inserting human genes to regulate immune responses and functions like blood clotting, creating sterile, custom-fitted organs within a seven-month growth cycle. While initially reserved for specific high-need patients, these bio-engineered transplants aim to eventually surpass the variable quality of human donors and expand access to life-saving treatments.

Are nitazenes the new fentanyl?
Emerging on the illicit European market in 2019, nitrooxenes are a class of potent synthetic opioids derived from 1950s research that cause fatal overdoses through highly toxic active metabolites. This dangerous trend surged following global supply disruptions to traditional heroin, leading to confirmed clusters in countries like Ireland where authorities discovered the drugs were being laced into other substances without user knowledge. While some nations implemented public warnings and harm reduction strategies, policy experts argue that continued punitive approaches fail to address the market dynamics driving the production of increasingly lethal synthetic alternatives.

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.

Could AI build cities in space?
Ed Mayer, Mark Woods, Alok Jha
Leading aerospace organizations and private innovators like Machina Labs and Relativity Space are deploying AI-guided robotics to establish autonomous manufacturing capabilities essential for constructing a trillion-dollar space economy by 2040. These dual-robotic systems and advanced 3D printing technologies address critical communication latency and maintenance challenges by enabling independent decision-making for infrastructure projects on the Moon and Mars. Ultimately, this technological paradigm shift facilitates NASA's Artemis program and private ambitions to transition from temporary exploration to a permanent, multi-planetary human presence.

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: Can vaccines keep up with variants?
Driven by the Delta variant and potential mutations within immune-suppressed hosts, the pandemic persists as unchecked global transmission threatens to create vaccine-evading "omega" variants. Experts warn that while current vaccines remain effective against severe outcomes, the primary risk lies in uncontrolled spread leading to higher absolute death tolls and future immune evasion. To prevent this nightmare scenario, scientists advocate for proactive surveillance at human-animal interfaces and the development of rapid variant-specific vaccines alongside stricter laboratory and environmental security protocols.
