Beyond The Headline: New Series Separates Science, Storytelling and Supposition

June 25, 2026 by Beyond GM

Every week we are told that a new technology is about to transform food and farming.

Gene editing will feed the world. Artificial intelligence will revolutionise agriculture. Precision fermentation will replace a range of foods from animal and plant sources. Nanotechnology will make crops more resilient. Engineering biology will solve climate change.

Some of these innovations may prove valuable. Others may not. But all too often the public conversation begins and ends with bold claims, eye-catching headlines and optimistic projections, while the evidence, assumptions and unanswered questions receive far less attention.

Today, Beyond GM launches Beyond the Headline, a new series of short, accessible briefings designed to help readers examine these claims more critically.

Each briefing asks a core set of questions:

  • What’s being claimed?
  • What evidence supports those claims?
  • What important uncertainties remain?
  • What assumptions are being made?
  • What alternatives are missing from the conversation?

The aim is not to dismiss innovation, but to improve the quality of public enquiry, discussion and decision-making around it.

The decisions being made today about food, farming and technology will shape agriculture, investment, regulation and consumer choice for decades to come. These decisions deserve scrutiny based on evidence rather than hype and techno-optimism.

Start here: Is photosynthesis really inefficient?

The first Beyond the Headline briefing examines recent claims surrounding a new nanotechnology-based ‘biostimulant’ developed by the Bristol-based company Glaia, which promises to “unlock the real potential of photosynthesis” and substantially increase crop yields.

At the heart of these claims lies a familiar narrative: that photosynthesis is surprisingly inefficient, converting only around 1% of sunlight into plant biomass, and that this represents an obvious opportunity for technological improvement.

Our briefing explores why this argument deserves much closer examination.

Photosynthesis is not a single process waiting to be optimised. It is one of the most complex biological systems on Earth, involving around 170 tightly coordinated biochemical processes that have evolved over hundreds of millions of years. Many features that appear “inefficient” actually perform essential protective functions that allow plants to survive changing environmental conditions.

The briefing also asks whether increasing photosynthesis necessarily leads to higher yields, examines the limited publicly available evidence behind current commercial claims, and considers whether investment might sometimes deliver greater benefits when directed towards improving soils, biodiversity and farming systems rather than attempting to manipulate plant physiology.

Importantly, it asks whether the evidence currently available justifies the confidence with which it is being promoted.

Looking beyond the headline

Across agriculture, food and what’s now being called “engineering biology”, increasingly sophisticated technologies are being presented as solutions to complex problems such as food security, climate change and sustainability.

In an increasingly technological society its up to all of us to become better informed.

The questions we must raise extend well beyond the PR boasts of a single product or company. The Government’s new Farming Roadmap 2050, for instance, is unashamedly techno-solutionist. It makes clear that emerging technologies – including engineering biology, artificial intelligence, precision breeding and other novel technologies – will play an increasingly central role in shaping the UK’s food system over the coming decades.

Whether or not one agrees with that direction of travel, it underlines the importance of asking challenging questions now, before these technologies become embedded in policy, regulation and investment decisions. Good decisions depend on more than technological promise. They require robust evidence, transparency about uncertainty and an honest assessment of alternatives. As the pace of innovation accelerates, the need to separate science, storytelling and supposition has never been greater.

With Beyond the Headline, Beyond GM hopes to create a space where scientific claims can be explored carefully, assumptions challenged respectfully and public debate strengthened through evidence rather than slogans.
