SIGNAL No.17 — Forest carbon credits are being sized for a climate that no longer exists

01 — Fashion and culture are learning to digitise the dossier, not the surface

• Cambridge Core walks through the digitisation programme behind the Yorkshire Fashion Archive and the essay treats the work as a knowledge problem rather than a photography one — a coat is soft, it drapes differently on a hanger than on a body, it carries interior structures and symbolic meanings that a single image cannot show, and the methodology being written down alongside each garment is what lets the digital copy survive being read as evidence twenty years on rather than as decoration
• Formula D maps six experiential design trends now baseline for museum exhibitions in 2026 — motion sensors that detect where visitors stand, cameras that read where they look, projection systems that respond in real time, walls and floors that change as a room fills — and reports that audiences arrive expecting to feel, hear, move and play through an exhibit rather than only look at it, so multi-sensory design has shifted from experimental kit to operating principle, with sound and texture and movement treated as first-class media alongside the visual

02 — Technology and bodies are being rewired together, and so is the policy around the wires

• Frontiers in Virtual Reality reports a study of wearable haptic guidance for motor rehabilitation in immersive VR, finding that elaborate force feedback is not what produces the gain — minimal vibrotactile cues, integrated with what the patient sees and hears in the headset, are enough for measurable improvements in motor control, because multisensory integration in the brain treats the combined signal as one coherent guide, and the practical consequence is that the cost of useful rehabilitation hardware just dropped from a robotic arm to a simple wearable vibrator paired with a moderate headset
• MIT Technology Review names mechanistic interpretability — the science of reverse-engineering a neural network to identify the specific features, circuits and pathways behind any output — one of its ten breakthrough technologies for 2026, and the applied evidence is concrete: Anthropic used the technique in pre-deployment safety assessment of Claude Sonnet 4.5, OpenAI is building an AI lie detector from model internals, and a recent study finds reasoning models mention their actual reasoning hints only about a quarter of the time, which is the kind of number that turns interpretability from a research luxury into a safety priority
• Submarine Networks reports the introduction of the bipartisan Strategic Subsea Cables Act of 2026 in the US Congress — the bill requires the State Department to staff dedicated subsea cable diplomacy, expands American participation in the International Cable Protection Committee, mandates sanctions on actors responsible for intentional cable damage, and stands up a White House interagency committee for national cable policy, putting the cables that carry more than 95% of international data traffic into the named-infrastructure column alongside power grids and pipelines

03 — The carbon books are being audited from the canopy down to the microbes

• Nature publishes a University of Utah-led international study finding that the buffer pools backstopping forest carbon credits — the reserves set aside in case protected trees burn, dry out or are killed by pests — have been sized for a climate the world no longer lives in, and for the first time the team maps how disturbance risk varies in space and time, which honestly read means a portion of forest carbon credits being sold today are over-promising and the corporate climate plans leaning heavily on them will need either larger buffer pools or fewer offsets
• PNAS runs a cross-national experiment showing that exposure to attribution messaging — communications that tie a specific extreme weather event in someone's own country to climate change — significantly raises public support for climate policy across countries, reframing attribution science from a careful hedged conversation inside academic papers into a tested instrument of political communication and forcing the field to confront what its public role and ethics should look like
• Phys.org / Johns Hopkins reports the launch of BioDIGS — the BioDiversity and Informatics for Genomics Scholars consortium — which has put around 150 researchers and students across more than 40 sites on a coordinated effort to systematically catalogue the soil microbiome of the United States, building the dirt's equivalent of a star atlas because the genome of the ground under American feet has been read in patches but never as a national reference dataset, and recent PNAS work showing soil microbial diversity shrinks with warming has made that baseline urgent
