The famed Northwest Passage—a direct shipping route from Europe to Asia across the Arctic Ocean—is ice free for the first time since satellite records began in 1978, scientists reported Friday.

The passage is a shortcut between the Atlantic and Pacific Oceans through the Canadian Arctic. It would save valuable time and fuel for ships that now travel through the Suez Canal in Egypt or the Panama Canal in Central America.

Salt Water Can “Burn,” Scientist Confirms

Salt water can indeed burn when exposed to a certain kind of radio wave, a university chemist has confirmed.

Rustum Roy of Pennsylvania State University verified earlier this month that the radio waves break the water into its components, allowing the resulting freed hydrogen and oxygen to catch fire.
