A detailed walkthrough of how old insurance maps — originally drawn for fire-risk assessment in the 19th and early 20th centuries — are being automatically aligned to modern geographic coordinates. The project (mapsnap) combines computer vision, historical geography, and open data in a way that reveals how much spatial information was embedded in pre-digital mapping. It's a clear example of 'clever repurposing': taking artifacts designed for one era's risk models and making them legible to today's GIS tools.

An interactive map that visualizes the changing geography of what is now the United States across deep geological time — from the breakup of Pannotia through the assembly of Pangaea and into the modern continent. What makes this compelling is the spatial framing: rather than a timeline or abstract diagram, it lets you scroll through continental drift as a map you can explore, making deep time intuitive rather than conceptual. A strong demonstration of cartography as a tool for understanding processes that operate far beyond human observation.

A visualization project tracing how US tariffs on Canadian goods ripple through specific businesses and supply chains. The map moves beyond aggregate trade statistics to show individual companies and their dependencies, making an abstract trade policy tangible at the scale of actual economic activity. It's a good example of cartography doing argumentative work — using spatial data to show who is affected and where, rather than just illustrating a number.

An investigation into the unusual legal and logistical fate of the trove of classified documents Edward Snowden leaked in 2013. The piece traces how the archive was split, stored, and ultimately handled by different journalists and organizations, raising questions about access, accountability, and whether the full story has ever been told. For anyone interested in how high-stakes institutional secrets actually get managed — not just the initial leak but the long tail of what happens next — this is a substantive look at an episode that most coverage has moved past.

Satellite imagery has become a tool for wildlife biology in an unexpected way: emperor penguin colonies are large enough, and their guano stains the ice distinctively enough, that researchers can identify and monitor colonies from orbit. What makes this piece interesting is the methodology — it's not just 'satellites can see penguins' but an explanation of how spectral signatures, seasonal timing, and ground-truthing combine to turn a joke premise into a legitimate conservation monitoring technique. A neat intersection of remote sensing and ecology.

NASA's Lunar Reconnaissance Orbiter has identified the largest newly-formed crater ever detected on the Moon, alongside an unexpected thermal emission signature that has scientists rethinking how impacts redistribute heat across the lunar surface. The discovery matters because it challenges existing models of how the Moon's surface behaves after a fresh impact — and because finding large new craters at all is a reminder that the Moon is geologically alive in ways satellite imagery is only beginning to document systematically.

An art exhibition that uses photography not to document what happened, but to imagine the life that was cut short — a speculative visual biography of Emmett Till as an adult. The project wrestles with photography's role in bearing witness versus its capacity for counterfactual storytelling, raising questions about whether images are best used to record reality or to insist on the futures that violence foreclosed. It's an example of photography as a conceptual and ethical medium, not just a documentary one.

A through-hiker's account of the White Mountains section of the Appalachian Trail, a stretch famous among long-distance hikers for its combination of exposed ridgelines, unpredictable weather, and relentless elevation change. The piece captures the gap between the reputation of a place (built up over 1,800 miles of trail rumors) and the actual experience of walking through it. For anyone interested in how landscapes acquire mythologies and how those stories shape the people who travel through them, it's a well-observed narrative.

A data-visualization-driven look at how income and spending inequality have evolved in America, presented as part of a continuing series. The piece uses clear, well-designed charts to show not just the gap between high and low earners, but how consumption patterns diverge at different income levels — a more textured picture than a single Gini coefficient provides. It's data journalism that rewards a few minutes of focused attention with a genuinely clearer understanding of an economic trend.

A joint European-Japanese mission that has spent nearly a decade navigating the inner solar system is about to reach its target: Mercury, the least-explored rocky planet. The probe will study the planet's magnetic field, geology, and tenuous exosphere — data that could answer fundamental questions about how the inner planets formed and why Mercury has such a disproportionately large iron core. It's a reminder that planetary science often operates on decade-long timescales, and that the payoff for patience can be substantial.
