Dark matter is a no show in ghostly galaxy

Galaxies and dark matter go hand in hand; you typically don’t find one without the other. So when researchers uncovered a galaxy, known as NGC1052-DF2,...
A look into the fourth dimension

A look into the fourth dimension

In our daily experience space has three dimensions. Recently, however, a physical phenomenon that only occurs in four spatial dimensions could be observed in two...

Researchers find new way of exploring the afterglow from the Big Bang

Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave...

How to bend and stretch a diamond

The brittle material can turn flexible when made into ultrafine needles, researchers find Diamond is well-known as the strongest of all natural materials, and with...

Device creates negative mass — and a novel way to generate lasers

Most objects react in predictable ways when force is applied to them—unless they have “negative mass.” And then they react exactly opposite from what you...

Hot bodies are attractive

Our physical attraction to hot bodies is real, according to UC Berkeley physicists. To be clear, they’re not talking about sexual attraction to a “hot”...

Is it time to abandon the Nobel Prize?

In a commentary piece published in Clinical Chemistry and Laboratory Medicine, researchers Clare Fiala and Eleftherios P. Diamandis spawned a debate now further nourished...

Computer searches telescope data for evidence of distant planets

Machine-learning system uses physics principles to augment data from NASA crowdsourcing project As part of an effort to identify distant planets hospitable to life, NASA...

What happens when nanoparticles collide

New research on what happens when nanoparticles collide could one day inform the development of better helmets, protective earphones, and even devices to convert...

Circumbinary castaways: Short-period binary systems can eject orbiting worlds

Planets orbiting “short-period” binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host...
