As an embryo grows, there is a continuous stream of communication between cells to form tissues and organs. Cells need to read numerous cues from their environment, and these may be chemical or ...

What is an electric field? What is a magnetic field? This exploration began with such simple questions. I was supposed to be ...

A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of ...

The exploration that began with the N and S poles of a magnet has finally returned to the 'self that sees.' No, rather than ...

A loophole in a result from classical electromagnetism could allow a simple device on the Earth’s surface to generate a tiny electric current from the planet’s magnetic field. Tapping into Earth’s ...

Polymer dielectric breakdown mechanism resolved: physicists at Russia's Ioffe Institute confirmed quantum tunneling drives electrical failure in PET film, not electron collision. New lifetime ...
