Hours of research by our editors, distilled into minutes of clarity.
Astronauts primarily consume freeze-dried meals, which are rehydrated with water recycled from urine and perspiration, directly from bags. Condiments and select cultural items from crew members can enhance the meal experience by boosting flavor. Many individuals report experiencing "food fatigue" due to a lack of fresh produce, limited menu variety, and lingering scents.
Most of the United States' Heinz ketchup is produced at the northeast Ohio plant, which has been open since 1937.
In the 1980s, archaeologists finally deciphered Maya hieroglyphs in part by identifying known words. Maya scholar David Stuart notes that cacao—still used today—was one of the key linguistic anchors that unlocked ancient Maya texts.
The resulting vibrations of these molecules produce heat between adjacent matter, much like how one's hands warm when rubbed together. The mesh in front of an oven's door confines the microwaves to the container, while the rotating plate allows different parts of food to travel through regions of maximum vibration.
3D printing food requires integrating ingredients with a variety of properties, which may not all resist the physical stress of stacking. This means successful 3D printing of food may require rethinking how ingredients are layered and modifying ratios of each, potentially sacrificing taste for structural integrity.
Microbes break down proteins and fats and produce compounds with distinct tastes. These microbes can include bacteria (like the one used to give Swiss its trademark holes), molds (like the ones that give blue cheese its distinctive veining), and countless other tiny organisms.
The ubiquitous handheld snack started in New York City, where vendors sold sausages in buns, calling out "Get your dachshund sausages!" Historians believe the change to "hot dog" was natural for many fans, who found the name funny and catchy.
While news reports may claim cheese is addictive, the facts behind the research show cheese and crack have little in common. It appears that highly processed foods with high levels of sugars and fat, rather than cheese specifically, are most closely associated with addictive-like behaviors. In fact, cheese ranked lower than foods like pizza, chocolate, and fries in terms of its addictiveness.
We might associate vegan cheese with current health trends, but there’s actually been a small-but-growing market for plant-based cheeses since the 19th century. But for vegan cheeses to appeal to a wider demographic, they have to compete with the familiar flavors and textures of dairy cheeses.
This charming infographic looks at the cheese-related habits of Europe’s top three cheese-producing countries: Italy, France, and Switzerland. Cheeses in France are reported to be the lightest, and Swiss cheeses the heaviest.
Art, music, sports, entertainment, movies, and many other subjects—these elements define who we are as a society and how we express ourselves as a culture. Take a deep dive into the topics shaping our shared norms, values, institutions, and more.
