Scientists unlock low-cost material to shape light for industry

Researchers in Australia have found a way to manipulate laser light at a fraction of the cost of current technology.

Exotic atomic nuclei reveal traces of new form of superfluidity

Recent observations of the internal structure of the rare isotope ruthenium-88 shed new light on the internal structure of atomic nuclei, a breakthrough that could also lead to further insights into how some chemical elements in nature and their isotopes are formed.

Is There Gravity in Space?

Gravity is everywhere, even in space.

Does the Universe Need Dark Matter to Form Galaxies? A Controversial Model Says 'No'

A new computer simulation can form galaxies without the need for dark matter. Overcoming this hurdle has been a long-standing challenge for supporters of a controversial theory of the universe that claims dark matter doesn’t exist.

Producing single photons from a stream of single electrons

Researchers at the University of Cambridge have developed a novel technique for generating single photons, by moving single electrons in a specially designed light-emitting diode (LED). This technique, reported in the journal Nature Communications, could help the development of the emerging fields of quantum communication and quantum computation.

Electrons in rapid motion

Researchers observe quantum interferences in real-time using a new extreme ultra-violet light spectroscopy technique.

Deconstructing Schrödinger's cat

Many physicists have attempted to explain the problem of quantum superposition, as exemplified by Schrödinger's cat. Now a French theoretical physicist proposes a novel possible solution, which combines two different approaches and brings in universal gravitation.

Betelgeuse is Dimming and Changing Shape, New Image of Its Surface Reveals

The nearby red supergiant has been dimming for a while now, but its exact fate is still unknown.

What Will a Betelgeuse Supernova Look Like From Earth?

Astronomers simulated what humans will see on Earth when the star Betelgeuse explodes as a supernova sometime in the next 100,000 years. 

The 'electronic Griffiths phase' in solid-state physical systems

Most theories of solid state and soft matter physics were developed independently; thus, a few physical concepts are applicable to both. Recent research, however, particularly a study by Elbio Dagotto, found that correlated electrons in solid-state physical systems can sometimes present a spatially inhomogeneous phase accompanied by extraordinarily slow electron dynamics, which resembles a phase observed in soft-matter systems.
