How a Museum Cares for a Giant Chunk of Dried-Out Fat

Andy Holbrook first laid eyes on the fatberg in October 2017, the day before his birthday. A collections care manager with nearly two decades of experience under his belt, he’d been dispatched by his colleagues at the Museum of London to pay a visit to “a slightly baffled but quite amused” team at Thames Water, the local sewage utility, to see about harvesting a slice of the congealed behemoth to display at the museum. “It felt like the most bizarre birthday present ever,” Holbrook says.

This fatberg, allegedly the largest ever hauled from any sewer, threw a famously putrid roadblock in London’s subterranean infrastructure in 2017. Fatbergs are often comprised of a slurry of used napkins, diapers, and other squishy detritus. This particular gloopy mess of … Read the rest

Mapping the ‘Conflict Zones’ Between Sprawl and Biodiversity

By 2030, the world is expected to add another billion people or so, bringing the total population to roughly 8.5 billion. And with humans becoming increasingly urban, sprawl will only get worse, taking up precious space that wild birds, mammals, plants, and the like can still call home.

In fact, at least 423 large cities (that is, with more than 300,000 people) across the globe are nestled inside 36 biodiversity hotspots: regions that harbor a high diversity of animal and plant species found virtually nowhere else in the world. And considering the growth trajectory of these cities—as modeled by the Seto Lab at Yale University—a staggering 90 percent of them could end up destroying the natural habitats of endangered species over the next decade or … Read the rest

A solar panel on every roof in the US? Here are the numbers

Enlarge (credit: Jon Callas)

When you’re scoping out possible futures, it’s useful to ask a lot of “what if?” questions. For example, what if we could install solar panels on every suitable roof in the United States? How much electricity would they generate?

Plenty of research has followed this line of thought, though much of it has necessarily focused on working out the details for individual cities or regions. But now with enough of these studies in the bank, a group of researchers from the US National Renewable Energy Laboratory decided to take another whack at a national estimate.

There are a lot of things you need to know to do this: number of buildings, size of roofs, direction the roofs are facing, strength of

Cities: Don’t Just Wait for the Feds

Last week, City Observatory’s Joe Cortright provided a caustic review of our book, The New Localism: How Cities Can Thrive in the Age of Populism. In his piece, “Cities Alone Can’t Fix What’s Wrong with American Government,” Joe acknowledges the rising power of cities as problem solvers, but also argues that fighting to preserve a “competent, generous, fair and functional” national government must be the highest priority during these dangerous times. He contends that “[t]he clarion call to act locally diverts our political attention from the national stage and perhaps, unwittingly, becomes an excuse to stand by and watch these foundational programs be destroyed.”   

We have been big admirers of Joe’s work over the years and welcome his voice in the debate. We … Read the rest

A Mustache Guard to Help You Drink Like a Victorian


Whisker Dam

$19.99, Amazon

Back in the Victorian era, protecting one’s mustache was an important concern for high society tea drinkers, which led to the invention of the “mustache cup.” These were tea cups or mugs with a thin strip of ceramic just inside the rim that acted as a guard for the drinker’s facial hair.

Mustache cups are not the hot trend they may once have been, but facial hair is as popular as ever. Enter the Whisker Dam. Place one on the rim of nearly any standard glass or mug, and suddenly you’ve got your very own Victorian mustache cup. This particular brand of mustache guard also features a rugged, heritage look that pairs well with a cup of coffee or a pint of … Read the rest
