New analysis shows a way to self-propel subatomic particles
Some physical principles have been considered immutable since the time of Isaac Newton: Light always travels in straight lines. No physical object can change its speed unless some outside force acts on it.
Explainer: How do satellites orbit the Earth?
Take a look at the moon and it isn't hard to imagine it as a planet. A 3,476 kilometres-in-diameter ball of rock, with basalt plains and mountain ranges, whose gravitational pull produces tides here on Earth.
Should physicists work to the sound of silence?
In this month's issue of Physics World, Felicity Mellor, a senior lecturer in science communication at Imperial College London, questions whether the requirement of the modern physicist to collaborate and communicate is pre ...
Scientists find a practical test for string theory
(Phys.org) —Scientists at Towson University in Towson, Maryland, have identified a practical, yet overlooked, test of string theory based on the motions of planets, moons and asteroids, reminiscent of Galileo's ...
Hubble sees a cosmic caterpillar
(Phys.org) —This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also ...

'One real mystery of quantum mechanics': Physicists devise new experiment
What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both particles and waves simultaneously. ...
Cosmic calculations: Advance will help astrophysicists explore where stars are born
A University of Delaware-led research team reports an advance in the June 1 issue of Science that may help astrophysicists more accurately analyze the vast molecular clouds of gas and dust where stars are bo ...
