Single molecule can shift the phase of a laser beam

(PhysOrg.com) -- The ability to control light forms the basis of many technologies, from microscopy to optical computing. Now, a team of scientists from ETH in Zurich, Switzerland, has demonstrated that a single organic molecule ...

Primordial weirdness: Did the early universe have 1 dimension?

(PhysOrg.com) -- Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010.

The music of gravitational waves

A team of scientists and engineers at NASA's Jet Propulsion Laboratory has brought the world one step closer to "hearing" gravitational waves -- ripples in space and time predicted by Albert Einstein in the early 20th century. ...

New phenomenon found in internal waves

(PhysOrg.com) -- Internal waves -- huge but nearly invisible ripples that occur in the oceans, the atmosphere and stars -- can play an important role in climate change and other processes, but there is plenty about them that ...

Most precise test yet of Einstein's gravitational redshift

(PhysOrg.com) -- While airplane and rocket experiments have proved that gravity makes clocks tick more slowly - a central prediction of Albert Einstein's general theory of relativity - a new experiment in an atom interferometer ...

Double engine for a nebula

(PhysOrg.com) -- The new image, showing a very rich field of stars towards the Carina arm of the Milky Way, is centred on the star HD 87643, a member of the exotic class of B[e] stars [1]. It is part of a set of observations ...

Powerful New Technique to Measure Asteroids' Sizes and Shapes

A team of French and Italian astronomers have devised a new method for measuring the size and shape of asteroids that are too small or too far away for traditional techniques, increasing the number of asteroids that can be ...
