For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...
Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...
The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the poles to the reliability of GPS on a jet’s navigation screen. When that ...
Despite the fact that our universe is electrically neutral, atoms found throughout the universe can be positively charged nuclei or negatively charged electrons. When these charges accelerate, they ...
WEST LAFAYETTE, Ind. — Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes (BNNTs) containing spin qubits, or spin defects. The BNNTs are more sensitive ...

Earth’s magnetic field flips often, and some reversals drag on 70,000 years
Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...
New results from China’s Chang’e 5 mission suggest that the Moon possessed a magnetic field well into its midlife, much longer than previously documented. In work published Jan. 1 in Science Advances, ...
Tongcang Li, a professor of physics and electrical and computer engineering, leads a team that has developed the BNNTs with optically active spin qubits. He also is on the faculty of the Purdue ...
