Understand why the electric force can be zero in electrostatics by exploring charge interactions, symmetry, and superposition. This video explains the physical intuition and mathematical reasoning ...

Moon dust is sharp, corrosive, and potentially fatal. NASA’s new electric force field shield is designed to blast it away.

A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why engineers at the University of Colorado Boulder are building what sounds ...

Researchers have discovered that ferroelectric fluids can harness an overlooked transverse electrostatic force (TEF) to rise over 80 mm, without magnets or high voltages. By exploiting the fluid’s ...

Ferroelectric fluids use a strong transverse electrostatic force to climb 80 mm, enabling lightweight, low-voltage motors and compact energy-efficient actuators. (Nanowerk News) Researchers have ...

Our annual World Air Forces directory – published in association with Embraer and data partner Cirium – details the military aircraft fleets of 161 nations, and analyses the main events of the last 12 ...

Chalmers researchers have developed a simple, light-based platform to study the mysterious “invisible glue” that binds materials at the nanoscale. Gold flakes floating in salt water reveal how quantum ...

Researchers wanted to quantify how much charge a jumping parasitic roundworm needed to latch on to its fruit fly host.Credit...By Victor M. Ortega-Jimenez Supported by By Alexa Robles-Gil For small ...

BUFFALO, N.Y. — Tiny solid particles – like pollutants, cloud droplets and medicine powders – form highly concentrated clusters in turbulent environments like smokestacks, clouds and pharmaceutical ...
