This image shows Earth’s tectonic plates, and the location of earthquakes and volcanic activity along the plate boundaries.
What causes earthquakes, and why are they so unpredictable? Seismic waves that pass through the planet hold the answer to these questions. Their patterns can reveal hidden dynamics—hotspots, deep-diving rock, melting mantle—in Earth’s interior.
Watch a video featuring the group that is installing seismometers across the United States, and check out our SeismoDome event, happening tonight in the Hayden Planetarium.
”Takara Tomy promised us that maglev technology would make its way to playsets next year, when we spoke at this year’s Tokyo Toy Show. It had two very different toys on hand, one a train that the company claims can reach up to 600 KPH (relative to its scale, at least). ” - High-speed maglev toys are coming in 2015
Jersey to become a “Bitcoin Isle” would be a good endorsement for the cryptocurrency.
There are advantages to being a tiny, self-governing speck in the English Channel, and the ability to create a “welcoming” financial habitat is certainly one of them. But Jersey has ambitions beyond just being a haven for regular cash. Its Treasury Minister, Senator Philip Ozouf, says he wants the island become a pioneer in the use of crypto-currencies too, and he’s backed up by a campaign group that’s dedicated to creating the world’s first “Bitcoin Isle.” (via Tax haven Jersey now wants to become ‘Bitcoin Island’)
Melting Arctic Opens Passages for Invasion For the first time in roughly two million years, melting Arctic sea ice is connecting the north Pacific and north Atlantic oceans. The newly opened passages leave both coasts and Arctic waters vulnerable to a large wave of invasive species, biologists from the Smithsonian Environmental Research Center assert in a commentary in Nature Climate Change.
Two new shipping routes have opened in the Arctic: the Northwest Passage through Canada, and the Northern Sea Route, a 3,000-mile stretch along the coasts of Russia and Norway connecting the Barents and Bering seas. While new opportunities for tapping Arctic natural resources and interoceanic trade are high, commercial ships often inadvertently carry invasive species. Organisms from previous ports can cling to the undersides of their hulls or be pumped in the enormous tanks of ballast water inside their hulls. Now that climate change has given ships a new, shorter way to cross between oceans, the risks of new invasions are escalating.
