What do we see in a mirror?

New metasurfaces look “bright” at one direction, while “dark” for the opposite direction. Researchers at Aalto University developed metasurfaces with extreme angle-asymmetric response. The new device...

Physicists record “lifetime” of graphene qubits

This could provide stepping stone to practical quantum computing. Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a...

Our universe is an expanding bubble in an extra dimension

Uppsala University researchers have devised a new model for the Universe - one that may solve the enigma of dark energy. Their new article, published...

What a tiny electron can tell us about the structure of the universe

What is the shape of an electron? If you recall pictures from your high school science books, the answer seems quite clear: an electron is...
Strong interactions produce a dance between light and sound

Strong interactions produce a dance between light and sound

Light and high-frequency acoustic sound waves in a tiny glass structure can strongly couple to one another and perform a dance in step. A team...

Four-dimensional physics shown in two dimensions

For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials that were theorized...

Why does nuclear fission produce pear-shaped nuclei?

Nuclear fission is a process in which a heavy nucleus split into two. Most of the actinides nuclei (plutonium, uranium, curium, etc) fission asymmetrically with...

Bizarre ‘dark fluid’ with negative mass could dominate the universe

It’s embarrassing, but astrophysicists are the first to admit it. Our best theoretical model can only explain 5% of the universe. The remaining 95% is...

Scientist discover rare fossil from the Big Bang in distant universe

A relic cloud of gas, orphaned after the Big Bang, has been discovered in the distant universe by astronomers using the world's most powerful...

Time travel is possible – but only if you have an object with infinite...

The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We’re doing...
