The Victorian queen of ice cream

Agnes Marshall invented "ices," the Victorian equivalent of ice cream, through her books and equipment, as shown in the pictures below.

When did people start making and using glass?

This article details the search for the ancient origins of glass, a now-common item through which archaeologists can spot histories of trade and innovation. Bronze Age glass was made from crushed quartz instead of sand, and artisans could color glass with materials such as cobalt. These trace metallic add-ons have given scientists a vital clue into the origins of glass, which is currently debated as either Egypt or the Near East.

The mystery of the cucumber, from coiling tendrils to its bitter, mature fruit

Cucumus sativus was first cultivated 3,000 years ago in the Himalaya of India, appearing in ancient Sanskrit hymns in the Hindu tradition. They are typically harvested well before maturation, as their yellow, final fruit is bitter. Their coiling tendrils were so distinct they prompted famed naturalist Charles Darwin to publish one of his lesser-known works, "On the Movements and Habits of Climbing Plants." Its refreshing coolness inspired cucumber-derived body washes and sprays over millennia.

Ice ages are periods of glaciation that last tens of millions of years

During these periods, Earth grows cold and is covered in massive continental ice sheets. Scientists have outlined at least five major ice ages, which result from the alignment of complex factors, like the flow of ocean currents and the movement and location of tectonic plates.

The rice in sushi wasn't originally intended to be eaten

In Southeast Asia in the third century, rice, mixed with salt, was used to preserve fish for several months. The rice was considered too salty to eat and was often thrown away, though adventurous eaters, over time, began eating the rice. In 16th-century Japan, rice was often mixed with vinegar rather than salt, a practice that eventually led to the modern version of sushi. “Sushi” roughly translates to “vinegared rice.”
