Mammoth Undertaking
Woolly mammoths thrived during the Pleistocene ice ages and died off about 4,000 years ago. But a recent study has uncovered new secrets about the ancient animals, which stood about 10 to 12 feet (3 to 3.7 meters) tall and weighed between 6 and 8 tons (5,500 and 7,300 kg). The study revealed a 3-D configuration of a woolly mammoth’s chromosomes—mapping that has never been done with ancient DNA—offering fresh insights into these bushy behemoths.

Today is World Emoji Day, a celebration of those little pictograms used widely throughout social media, texting, email, and other computer-mediated communications. But where do emojis come from and how did they become ubiquitous?
Soon after, in Japan another style of emoticon known as kaomoji, meaning “face marks,” developed. Whereas Western-style emoticons were to be read sideways, kaomoji were presented right side up and were often more complex in what they represented, such as a person wearing headphones or kneeling in apology.
In 1999 Japanese software developer Shigetaka Kurita created a series of 176 colorful pictorial icons for a cell phone company. These emojis depicted concepts that were simple yet universal, such as weather, moods, foods, and animals. Kurita is often credited for the invention of the emoji, though it is now thought that Japanese conglomerate SoftBank released the first set of emojis in 1997 for its phone carrier. The set was smaller, with 90 icons, depicted in black and white. The designer of this set is unknown.
