Human languages are known to have grown and changed considerably over the course of history, often reflecting technological, cultural, and societal shifts. Studying the evolution of languages can thus offer valuable insight ...
It takes a moment for the eyes to adjust. A faint spark appears in the darkness; then another, brighter one. Soon, stars, planets and entire constellations emerge. Before long, a whole galaxy stretches across the sky, visible ...
A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen phenomenon: radio pulses generated when high-energy cosmic rays slam into the ice sheet and trigger ...
Quartz crystals are difficult to knap due to size, hardness, and crystalline structure, making them a "low-quality" raw material. However, the Clovis people of North America sometimes made points and other tools from this ...
Catalysis—the reduction of activation energy in a chemical reaction by a catalyst—plays a key role in the chemical industry, as well as in the development of sustainable technologies essential for achieving a low-carbon economy. ...
For some time, researchers have assumed that solid materials could gain more useful properties by making their microscopic components more active. Now, a team led by Jack Binysh at the University of Amsterdam has found that ...
Many important objects in the world can be divided into two categories based on their chirality or handedness, including molecules important for life such as amino acids. Such chiral objects (formally defined as objects which ...
Researchers have demonstrated the first "all-in-one" cocatalyst for photocatalytic overall water splitting, a breakthrough that could simplify the production of clean hydrogen fuel. The discovery marks an important step toward ...
Carbon nanotubes are one technology that many observers believe hasn't quite lived up to the extreme hype that surrounded them when they first appeared on the scene in the late 1990s. At that time, much was made of their ...
A research team has developed a high-efficiency electrochemical system that simultaneously produces hydrogen and value-added chemicals using glycerol, a low-cost, abundant byproduct of biodiesel production. The findings are ...
