To probe the origin of Earth’s magnetism, a team led by John Tarduno retrieved rock samples from the Jack Hills in Western Australia – home to some of the oldest rocks on the planet.
The Earth’s magnetic field, which shields the atmosphere from harmful radiation, is at least four billion years old, according to scientists.
Patches of ground where huts were burned down in southern Africa contain a key mineral that recorded the magnetic field at the time of each ritual burning.
Rochester, whose fortunes have risen and fallen with the demand for futuristic technologies from former powerhouses like Xerox and Kodak, is looking for its next big breakthrough in the field of integrated photonics, a light science with the potential to transform communications, medicine and national defense.
A $610 million research and manufacturing hub dedicated to the science of photonics — the use of light in technology — will be developed in western New York, federal and state officials said Monday, which could mean thousands of jobs for the region.
