Researchers find that Earth’s magnetic shield is 500 million years older than previously thought

July 30, 2015

Since 2010, the best estimate of the age of Earth’s magnetic field has been 3.45 billion years. But now a researcher responsible for that finding has new data showing the magnetic field is far older. John Tarduno, a Rochester geophysicist and leading expert on Earth’s magnetic field, and his team of researchers say they believe the Earth’s magnetic field is at least four billion years old.

Drawing a line between quantum and classical: Bell’s Inequality fails test as boundary

July 21, 2015

The best guide to the boundary between our everyday world and the “spooky” features of the quantum world has been a theorem called Bell’s Inequality, but now a new paper shows that we understand the frontiers of that quantum world less well than scientists have thought.

Now you see it, some day you won’t: scientists get closer to invisibility

July 13, 2015

Using lenses and meta-materials, science is finding new ways to bend or reroute light. Like Harry Potter’s cloak or H.G. Wells’ chemical concoction, it could make an object impossible to see.
