Going the distance for better wireless charging
A better way to wirelessly charge over long distances has been developed at Aalto University.
A 4D printer for smart materials with magneto-and electro-mechanical properties has been developed
Researchers at Universidad Carlos III de Madrid (UC3M) have created software and hardware for a 4D printer with applications in the biomedical field. In addition to 3D printing, this machine allows for controlling extra functions: programming the material’s response so that shape-changing occurs under external magnetic field, or changes in its electric properties develops under mechanical deformation.
Sudden Spin-down Event Illuminates Magnetar Mystery
A new paper published in Nature Astronomy is shedding light on magnetars, whose attributes remain poorly understood. A magnetar is a type of neutron star with an extremely strong magnetic field that rotates once every two to ten seconds. Researchers…
Urban Magnetic Fields Reveal Clues about Energy Efficiency, Pollution
In Journal of Applied Physics, researchers from the United States and Germany present a comparative analysis of urban magnetic fields between two U.S. cities: Berkeley, California, and the Brooklyn borough of New York City. They explore what kinds of information can be extracted using data from magnetic field sensors to understand the working of cities and provide insights that may be crucial for preventative studies.
Further evidence of 200 million-year cycle for Earth’s magnetic field
The findings of a new study by the University of Liverpool provides further evidence of an approximately 200-million-year long cycle in the strength of the Earth’s magnetic field.

Astronomers detect possible radio emission from exoplanet
By monitoring the cosmos with a radio telescope array, a Cornell University-led international team of scientists has detected radio bursts emanating from the constellation Boötes. The signal could be the first radio emission collected from a planet beyond our solar system.
Best Region For Life on Mars Was Far Below Surface
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what’s known as the faint young sun paradox – a lingering key question in Mars science.
Graphene expert comments on the creation of an extremely tiny magnetic field detector
“The research group from the University of Basel has recently created an ultracompact superconducting quantum interference device — aka SQUID, where the record miniaturization is achieved by using next-generation materials: bilayer graphene-based van der Waals heterostructures. SQUIDs usually consist of two…
DOE-funded UAH directed plasma research may advance pulsed fusion propulsion systems
A professor at The University of Alabama in Huntsville (UAH) has been awarded a one-year, $98,930 grant by the U.S. Department of Energy (DOE) for plasma research that could advance pulsed fusion propulsion for spacecraft.
The Magnetic History of Ice
The Weizmann Institute’s Prof. Oded Aharonson found that ancient ice holds magnetic particles. The finding could shed greater light on the Earth’s magnetic field reversals, supplement magnetic field data from rocks and sediment, and identify field reversals on other bodies in our Solar System, such as Mars.
