Stretching for thousands of miles beneath oceans, optical fibers now connect every continent except for Antarctica. But although optical fibers are increasingly replacing copper wires, carrying information via photons instead of electrons, today's computer technology still relies on electronic chips. Now, researchers are paving the way for the next generation of computer-chip technology: photonic chips.

For the last 10,000 years, summer sea ice in the Arctic Ocean has been far from constant. For several thousand years, there was much less sea ice in The Arctic Ocean -- probably less than half of current amounts, according to a new study.

Observations from NASA's Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on Mars.

Bones of South Pole dinosaurs grew like the bones of other dinosaurs, helping explain why dinosaurs were able to dominate the planet for 160 million years, new research shows.
