Norway's Doomsday Seed Vault Is Getting a $12.7 Million Makeover After Flood

Ten years ago, Norway build the Svalbard Global Seed Vault, a secure storage facility deep within an Arctic mountain designed to keep seeds from the world’s essential crops safe from any kind of disaster. Though it’s not the only seed bank, it is the world’s largest, with nearly 900,000 seed samples in long-term storage. And now, according to The Verge, the facility is due for a makeover worth more than $12.7 million.

Owned by Norway’s Ministry of Agriculture and Food and run by the Nordic Genetic Resources Center, the Svalbard Global Seed Vault is situated north of the Arctic Circle on an archipelago between mainland Norway and the North Pole. It acts as a backup library of seeds for the world’s major crops, providing a way to revive food sources if a country’s food supply is destroyed by natural disasters, warfare, or pests. The first of its seed deposits were withdrawn in 2015 to replace seeds samples from another gene bank destroyed in the Syrian civil war.

The seeds currently stored there are kept in vaults located almost 400 feet underground, ensuring that they will stay cold even if the mechanical cooling systems fail or as temperatures rise outside due to climate change. But now, 10 years after the mountain storage facility opened, it’s due for some upgrades to keep it running smoothly. On February 23, the Norwegian government announced a proposal to upgrade the infrastructure of the vault, including constructing a new access tunnel and a service building that will contain emergency power and refrigeration sources.

To keep seeds safe for future generations in perpetuity, the vault will have to be able to withstand the effects of climate change, which will include the melting of the permafrost that keeps the facility cool. In 2017, melting permafrost seeped into the vault, and while none of its samples was damaged, the failure does suggest that we can’t rely on permafrost to keep the vault’s treasure at a safe temperature if the mechanical cooling systems change. The new access tunnel will be more water-resistant, and the service building will keep sources of heat away from the vault itself. The work is scheduled to be done by May 2019.

Despite the melting permafrost, Svalbard is still considered one of the safest places in the world for really, really long-term storage. In March 2017, the seed vault got a new neighbor, the history- and culture-focused Arctic World Archive.

19 Must-Visit Stops on Mexico City's Metro

About 5 million people ride the Mexico City subway every day—but most commuters don’t realize how much there is to do and see without ever having to go above ground. From piano stairs to a space tunnel, exploring the attractions hidden within the metro just might be the most fun you can have for 5 pesos (about $0.25 USD). These Mexico City metro stations settle the old question once and for all; it’s both the journey and the destination.


Talisman station (line 4) has a mammoth logo for a reason: Mammoth fossils were unearthed during construction of the metro, and you can see the bones—which date back to the Pleistocene—on display there.

How do you make a long transfer fly by? Transform it into a walk-through space tunnel illuminated by a glow-in-the-dark night sky, the highlight of the science museum located within La Raza station (lines 3 and 5).


Viveros (line 3), a station named for the nearby nursery, is in full flower: It was recently given a jungle makeover complete with imitation palms, jaguars, and snakes to raise awareness for the preservation of southern Mexico’s Lacandon Rainforest.


Complement your day trip to the pyramids at Teotihuacan with a stop at the Pino Suarez station (lines 1 and 2), where you can see a 650-year-old pyramid dedicated to Ehecatl, the Aztec god of wind. Tens of thousands of users go through the station daily, making the pyramid one of the most visited archeological sites in Mexico. (Though it's referred to as Mexico’s smallest archaeological zone, the National Institute of Anthropology and History doesn't consider it a "proper" archaeological zone "due to its size and the fact of being located in a Metro Transport System facility.")


Hidalgo (lines 2 and 3) may be the most miraculous of all of Mexico City’s metro stations: In 1997, someone (possibly a street vendor) discovered a water stain in the shape of the Virgin of Guadalupe in one of its floor tiles. The apparition attracted so many pilgrims that metro authorities eventually had to remove the tile, which is now enshrined just outside one of the exits (follow the signs for Iglesia), near the intersection of Paseo de la Reforma and Zarco. And if you happen to visit this station on the morning of the 28th of any month, you’ll be swarmed with pious commuters carrying figurines of Saint Judas Thaddeus—patron saint of delinquents and lost causes—who is venerated at the nearby San Hipolito Church.


No time to visit the vast National Museum of Anthropology? You can still catch reproductions of Mesoamerican statues at the Bellas Artes (lines 2 and 8) and Tezozomoc (line 6) stops.

Miniature maniacs shouldn’t miss the scale models of Mexico City’s main plaza at the Zocalo stop (line 2). They depict, in tiny form, the metamorphosis of the capital from the Aztec Templo Mayor to the present-day Metropolitan Cathedral. (And bonus points to anyone who can spot the cat who lives in this station.)


The music-themed Division del Norte station’s (line 3) free karaoke corner draws a crowd gathered to watch fellow riders belt out boleros and ballads on their way to work. The unassuming abuelitas laden with bags from the market always have the most impressive pipes.

Don’t take the escalators at Polanco station (line 7), because the stairs are a giant musical piano keyboard. Finally, here’s your chance to live out Tom Hanks’s piano dance scene from the movie Big.


The Guerrero stop (lines B and 3) is a tribute to the legends of lucha libre, with costume displays and murals dedicated to 45 of Mexico’s finest masked fighters.


The largest bookshop in Latin America can be found in the long passage between the Zocalo and Pino Suarez stations. The underground emporium known as Un Paseo Por Los Libros sells titles from textbooks to manga and also hosts free workshops, lectures, and movie screenings.

Any visitor to Mexico City should check out Diego Rivera’s murals—but on your way, don’t forget to look up at the murals that decorate many metro stations. Particularly impressive are Guillermo Ceniceros’s ambitious chronicles of art through the history of time on the walls at the Copilco (line 3) and Tacubaya stations (lines 1, 7, and 9). On the kitschier side, see how many famous faces you can pick out in Jorge Flores Manjarrez’s I Spy-style mural of pop stars at the Auditorio stop (line 7).


A museum of caricatures located inside the Zapata stop (line 12) is an homage to Mexican cartooning, including plenty of satirical interpretations of the mustachioed revolutionary who gives the station its name.


If Chabacano station (lines 2, 8, and 9) feels unsettlingly familiar, it might be because it was used as a shooting location for the subway chase scene in the Arnold Schwarzenegger film Total Recall. Legend has it you can still spot splashes of fake blood on the ceiling.

Has this metro adventure turned you into a super fan? Do a deep dive at Mixcoac station’s (line 12) sleek Metro Museum, where you can learn even more fun facts about the subway’s 50 years of history while you wait out rush hour.

Some of the world's most beautiful and historic lighthouses can be found in the American Northeast. Now, Pop Chart Lab is releasing an illustrated poster highlighting 150 of the historic beacons dotting the region's coastline.

The 24-inch-by-36-inch print, titled "Lighthouses of the Northeast," covers U.S. lighthouses from the northern tip of Maine to the Delaware Bay. Categorized by state, the chart features a diverse array of lighthouse designs, like the dual towers at Navesink Twin Lights in New Jersey and the distinctive red-and-white stripes of the West Quoddy Head Light in Maine.
