Scientists develop low-cost system to measure space weather without leaving the ground

A research team from Nagoya University's Institute of Space-Earth Environmental Research (ISEE) built a magneto-impedance sensor magnetometer (MIM). It will measure variations in the Earth's geomagnetic field using an Aichi Steel Corporation sensor. Geomagnetic fluctuations are closely related to phenomena occurring in space. So, upper...

Gamma-ray pulsations detected from pulsar PSR J1835−3259B

Using NASA's Fermi space telescope, Chinese astronomers investigated PSR J18353259B, a newly discovered millisecond pulsar. As a result, they discovered gamma-ray pulsations coming from this source. The discovery is detailed in a paper published on the arXiv pre-print server on June 27. Pulsars are rotating...

Reconfigurable silicon nanoantennas controlled by vectorial light field

A new publication from Opto-Electronic Advances considers reconfigurable silicon nanoantennas controlled by vectorial light field. High-index dielectric particles can be induced with intense electric and magnetic multipole resonance under visible range. The interference between electric and magnetic multipole in particles will bring many novel optical properties....

Elastic fields stretch the understanding of chiral molecular crystals

Harnessing the properties of materials so that technology can continue to move forward means getting to grips with increasingly more challenging systems. Institute of Industrial Science at the University of Tokyo scientists have turned its focus to chiral molecular and colloidal crystals. It revealed...

Physicist solves century old problem of radiation reaction

Scientists have proposed a radical solution to the question of how a charged particle responded to its own electromagnetic field. Dr. Jonathan Gratus, mathematical physicist, has suggested an alternative approach as a solution to the question. The research has been published in Journal of Physics...

Scientists develop new method hunting for dead stars

Neutron stars are tiny in size but have incomprehensibly dense. They are stellar corpses. But they have some life in them to show some of the most exciting phenomena to be found in space. Scientists will be studying and looking for neutron stars for the next...
