Researchers Pinpoint the Genes Behind the Durian's Foul Stench

Durian is a popular fruit in parts of southeast Asia. It's also known for having the most putrid, off-putting odor of any item sold in the produce section. Even fans of durian know why the fruit gets a bad rap, but what exactly causes its divisive scent is less obvious. Determined to find the answer, a team of researchers funded by "a group of anonymous durian lovers" mapped the fruit's genome, as reported by the BBC.

The study, published in the journal Nature Genetics [PDF], contains data from the first-ever complete genetic mapping of a durian fruit. It confirms that durian's excess stinkiness comes from sulfur, a chemical element whose scent is often compared to that of rotten eggs.

Analysis of the fruit's chemical makeup has been done in the past, so the idea that sulfur is a major contributor to its signature smell is nothing new. What is new is the identification of the specific class of sulfur-producing genes. These genes pump out sulfur at a "turbocharged" rate, which explains why the stench is powerful enough to have durian banned in some public areas. It may seem like the smell is a defense mechanism to ward off predators, but the study authors write that it's meant to have the opposite effect. According to the paper, "it is possible that linking odor and ripening may provide an evolutionary advantage for durian in facilitating fruit dispersal." In other words, the scent attracts hungry primates that help spread the seeds of ripe durian fruits by consuming them.

The revelation opens the door to genetically modified durian that are tweaked to produce less sulfur and therefore have a milder taste and smell. But such a product would likely inspire outrage from the food's passionate fans. While the flavor profile has been compared to rotten garbage and dead animal meat, it's also been praised for its "overtones of hazelnut, apricot, caramelized banana, and egg custard" by those who appreciate its unique character.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Fried Beer Exists—and We Have Texas to Thank (or Blame) for It

For anyone who thinks beer can qualify as a meal, we have some non-scientific evidence to support your claim: it’s shaped like ravioli, it tastes like a soft pretzel, and it’s filled with warm, yeasty deliciousness.

It’s deep-fried beer.

The story behind this culinary triumph began more than 10 years ago at a bar in Texas, where Mark Zable and his wife were scanning another uninspired menu with the same few finger foods. Zable made an offhand comment about how the bar should offer fried beer, and the couple realized it wasn’t such a bad idea—especially for the state fair.

Zable, a corporate recruiter by day, was no stranger to fair fare. As he told NPR, his father had opened a Belgian waffle stand at Texas’s state fair in the 1960s, and Zable himself assumed control after about 30 years. He experimented with new items to enter into the Big Tex Choice Awards food competition—sweet jalapeño corn dog shrimp and chocolate-covered strawberry waffle balls were two of his innovations—but nothing had won him a prize … yet.

Though the concept of fried beer was wacky enough to show real promise, execution proved difficult. Dropping liquid into a deep-fryer is a good way to get splattered with boiling oil, and Zable spent more than two years trying to devise an edible vessel that could both contain the beer and protect the chef. Finally, his 4-year-old son inspired a new angle, and Zable landed on a flawless design. Though Zable’s been tight-lipped on the details of that recipe, the Toronto Star reports that it’s essentially soft pretzel dough pressed into a ravioli-like pocket, filled with Guinness, and plopped into the deep-fryer for 15 to 20 seconds.

“It tastes great,” Zable told NPR. “Tastes just like eating a pretzel with a beer.”

At last, Zable’s ambitious creation was ready for its debut at Texas’s 2010 state fair. He faced some tough competition at the Big Tex Choice Awards—including fried frozen margaritas, fried lemonade, and fried club salad—but even the other edible beverages were no match for Zable’s savory fusion of beer and bread. He took home the award for “Most Creative,” while “Texas Fried Fritos Pie” clinched “Best Taste.” Together, they’re a match made in state fair heaven.
