The last remaining master animal-skin parchment maker in the world demonstrates how paper was made in medieval Europe (and why it wasn’t for vegetarians).

The European printing revolution began in Germany in 1448 when goldsmith Johannes Gutenberg began casting letters in metal.

Just as handwritten records changed how societies work, the printing press transformed the spread of information, igniting the Industrial Revolution. How did technologies–from pen to paper to printing press—make it all possible?

Christian Cooper, board member of the New York City Audubon, hands out yearbook-style superlatives to numerous bird species and shares some memorable birding encounters.

Almost all the letters of the Latin alphabet are derived from the hieroglyphs that the Canaanites of Serabit chose to represent the sounds of their tongue.

For tens of thousands of years, Aboriginal culture has been handed down orally through song and poetry without the need to write anything down.

Meet COVID-19 patients who lost their sense of smell and doctors working to determine whether the condition, called anosmia, is permanent.

Writing shaped our world and the rise of human knowledge, from the trading of goods to tales of ancient goddesses and kings. Follow the evolution of the written word, from 4,000-year-old carvings in an Egyptian turquoise mine to modern-day alphabets.

The gas phosphine, made on Earth by microbial life forms, was found in Venus' atmosphere.

When presented with a buffet of custards with varying ratios of protein to sugar, slime mold selects its optimal food source.

Meet the charismatic slime mold Physarum—which can learn, make decisions, and go through mazes without a brain—and the researchers studying it.

Scientists investigate the bizarre “intelligence” of slime molds, which appear to learn and make decisions—without a brain. These cunning, single-celled blobs can navigate mazes and create efficient networks. Can they also redefine cognition?

In October 2020, a NASA spacecraft called OSIRIS-REx attempts to reach out and grab a piece of an asteroid named Bennu to bring it back to Earth. The OSIRIS-REx team has just three chances to extend its spacecraft’s specialized arm, touch down for five seconds, and collect material from the surface of Bennu.

With an extraordinary new technology called CRISPR, we can now edit DNA—including human DNA. But how far should we go? Gene-editing promises to eliminate certain genetic disorders like sickle cell disease. But the applications quickly raise ethical questions. Is it wrong to engineer soldiers to feel no pain, or to resurrect an extinct species?

Gene-edited babies could be free of sickle cell anemia. David Sanchez, a teen with the disease, shares his thoughts on living with sickle cell—and a possible future without it.
