High-speed imaging of charged droplet dynamics reveals a critical transition in the role of non-uniform AC electric fields on ...

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements ...

For about 20 years, Caltech Professor of Applied Physics Paul Bellan and his group have been creating magnetically accelerated jets of plasma, an electrically conducting gas composed of ions and ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

NASA scientists have discovered a planet-wide electric field surrounding Earth, confirming a 60-year-old hypothesis. Studying the field could yield some vital information about how our planet's ...
