Wisconsin's resurfacing of 2.2 miles of Highway 42 in Door County will keep every one of the road's 15 famous curves exactly where they are.

Wisconsin's coming resurfacing of the final 2.2 miles of Highway 42 in Door County is a mill-and-overlay on the existing alignment, which means the road's 15 famous curves — and the tunnel of trees around them — stay exactly where they are.

Early Earth

Classic Moon-formation simulations typically produced a ring of debris that assembled over months or years after a Mars-sized world struck early Earth. But simulations published in September 2026 that included temperature-dependent rock strength found that, under certain conditions, a coherent Moon-sized satellite could emerge in roughly five hours.

A September 2026 impact study found that strength retained by hot, partly solid rock can redirect Theia’s rebound and capture a coherent satellite within hours.

Political Economy

The figure quoted as $7.4 trillion in annual fossil fuel subsidies is mostly not money changing hands. About $6.7 trillion of it is damage the IMF says goes uncharged, three-quarters of that from air pollution and climate, on a definition other agencies reject.

Explicit fossil fuel subsidies came to $725 billion in 2024. The figure usually quoted is ten times larger because the IMF counts uncharged environmental damage as a subsidy as well, a definition the OECD and the IEA reject. The damage is not what is in dispute. The total attached to it rests on a contested accounting choice, and the mortality estimates underneath it differ by more than a factor of two.

Every year Australia slides seven centimeters toward the north-northeast, almost twice the pace of a growing fingernail and quicker than any other continent. Southeast Asia is already in the way, and some models fold the plate into a new supercontinent inside 300 million years.

A continent racing across the planet at twice the speed of growing fingernails is remaking the map—and threatening the region directly in its path.

Unsold and secondhand clothing piles up in dumps in Chile's Atacama desert, and a small factory nearby now shreds it and presses it into insulation panels. The boards going up inside the walls of new houses started out as garments nobody ever bought.

A Chilean factory is turning the fashion industry's waste into building material, transforming unworn imports destined for landfills into insulation that keeps homes warm.

Climate Science

Seismologists already knew big earthquakes send waves down to Earth's core and back, but Japan's 2011 quake was the first time those returning waves were shown to actually slip tectonic plates near the surface — a previously unrecognised source of seismic hazard.

About 13 minutes after Japan's 2011 magnitude 9.0 earthquake, GPS stations across the country registered a uniform 5–6 millimetre eastward shift with no aftershock to explain it. A 2026 University of Chicago study traced it to a seismic wave that bounced off Earth's outer core and slipped four tectonic plates — the first time such a deep-diving wave has been shown to trigger surface fault motion.

In 1963, Britain proposed closing 5,000 route miles of railway; by the late 2010s, about 1,200 miles of the National Cycle Network used old railway track beds, while more than 1,000 cast-iron Millennium Mileposts installed in 2000 marked routes across the network.

The Zeckendorf brothers bought the Mayflower Hotel for around $400 million in 2004 and cleared its rent-controlled tenants one by one with buyouts starting at $650,000, until a single 350-square-foot apartment held out and ultimately cost them $17 million to empty.

Flora and Fauna

In 1965, a bottlenose dolphin named Peter was taught to mimic English words in a flooded Caribbean house where researcher Margaret Howe Lovatt lived waist-deep in seawater with him for 10 weeks, and the dolphin learned to blow air through his blowhole to shape recognisable versions of 'hello' and 'ball'.

How does a rodent felling saplings across a headwater stream raise a valley's water table by a metre or more and store measurably more carbon in the wet sediment behind its dams than the trees it cut down?

Nearly 11,000 acres along the Mimbres River in southwestern New Mexico became a new Wildlife Management Area this month, carrying pre-1907 water rights and critical habitat for the yellow-billed cuckoo and Chiricahua leopard frog after Trust for Public Land closed the ranch with the state.

Iron and Ice

Jupiter is so massive that its shared centre of gravity with the Sun lies just outside the Sun’s surface — making it the only planet whose individual barycentre with the Sun falls beyond the Sun itself, and the largest contributor to the star’s planetary wobble.

On Washington’s Olympic Peninsula, after two dams came down on the Elwha River, average Chinook returns rose from 2,827 fish a year to 4,734 — and the share taken for hatchery breeding fell from 53 per cent to 31 per cent as more Chinook were left to spawn in the restored channel
