Transmitting data from space to earth with laser filaments

Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry far more information and move it faster ...

Shining a (UV) light on the glow-in-the-dark platypus

The fur of the platypus—an Australian species threatened with extinction—glows green under ultraviolet light, a new study finds. This is the first observation of biofluorescence in an egg-laying mammal (monotreme), suggesting ...

Surprisingly mature galaxies in the early universe

When the universe was only a tenth of its current age its galaxies experienced a growth spurt. It was this period that the scientists in the ALPINE project focused on when they used ESO's ALMA telescope to carry out the first ...

When Fock meets Landau: Topology in atom-photon interactions

Since the discovery of the quantum Hall effect, topological phases of electrons have become a major research area in condensed matter physics. Many topological phases are predicted in lattices with specific engineering of ...

Smart bulk plastic reacts to light, temperature and humidity

Imagine that products have a longer shelf life because of smart packaging, that plastic robots are driven by their environment, and that clothing adapts while being worn. In short: that you can make plastic smart so that ...
