We all like order in our lives (well, I do at least) but things rarely operate that way. In fact, the world is full of “aperiodic” order – patterns that aren’t totally repetitive but not completely random either. Aperiodic patterns can be found in Islamic art, such as the Tomb of [...]

Hot Jupiters are some of the most extreme planets in the galaxy. These scorching worlds are as massive as Jupiter, and they swing wildly close to their star, whirling around in a few days compared to our own gas giant’s leisurely 4,000-day orbit around the sun.Scientists suspect, though, that hot [...]

Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei (AGNs). [...]

Researchers in China have fabricated a new hybrid superconducting device from a special type of material known as an artificial spin ice (ASI). The innovative structure, which is made of asymmetric nanomagnets, could be used to build magnetic-field-driven superconducting diodes for use in energy-efficient electronics. ASIs get their name from the [...]

What made you decide to write this book? I wanted to share something I find very exciting, but also [show] how we do science and the fun in doing it. I think we are all scientists in that we can all explore and understand. Most of all, I wanted to connect [...]

Claudia de Rham decided early in life she wanted to be an astronaut. Her peripatetic childhood meant she spoke several languages, but imperfectly, and was drawn to science as a universal language – a more reliable base from which to understand the world. As her ambition to go into space [...]

Electrons have been sent along structured chiral paths by researchers in Germany. The researchers say their work, which is analogous to work done with photons in 2010, achieves chirality in single-electron matter waves without angular momentum. Some other researchers, however, are puzzled by this claim. In 2010, David Grier of New [...]

Neutrinos have a quantum mechanical property called "flavor." This flavor can transform as neutrinos move through space. A major challenge is to keep track of both the physical movement of the neutrinos and their change of flavor in astrophysical systems such as core-collapse supernovae and neutron star mergers. The complicated [...]

These stars provide compelling new evidence for the presence [...]

The qualities and behavior of dark matter, the invisible "glue" of the universe, continue to be shrouded in mystery. Though galaxies are mostly made of dark matter, understanding how it is distributed within a galaxy offers clues to what this substance is, and how it's relevant to a galaxy's evolution. [...]
