Diodes are used in an endless array of devices. They are essential ingredients for the semiconductor industry. Making diodes smaller means cheaper cost and better performance for electronic devices. ASU researchers have now made diodes on the scale of a single molecule.--by Richard Harth

Scientists are taking high-speed motion pictures of photosynthetic reactions that happen in a millionth of a millionth of a second. Their results have revealed a surprising twist to photosynthesis. --by Joe Caspermeyer

ASU researchers create intricate structures on a scale almost unfathomably small. Their building material is the DNA molecule, which offers nearly limitless construction potential. --by Richard Harth

Personalized medicine based on your unique genetic makeup may soon be a reality. New technology could reduce the cost and speed of sequencing the entire human genome to $1,000 in 24 hours. --by Joe Caspermeyer

The chemical makeup of the oceans has changed dramatically over billions of years. As a result, the ancient oceans are helping us understand how organisms and ecosystems evolve to cope with changing abundances of elements. --by Jenny Green

Why did the earliest life on Earth--mostly bacteria--remain virtually unchanged for a billion years? --by Diane Boudreau
