Study finds that patterns formed by spiral galaxies show that the universe may have a defined structure

An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links might suggest that the early universe could have been spinning, according ...

'Black nitrogen': Researchers discover new high-pressure material and solve a puzzle of the periodic table

In the periodic table of elements there is one golden rule for carbon, oxygen and other light elements: Under high pressures, they have similar structures to heavier elements in the same group of elements. But nitrogen always ...

A new view on how tissues flow in the embryo

As embryos develop, tissues flow and reorganize dramatically on timescales as brief as minutes. This reorganization includes epithelial tissues that cover outer surfaces and inner linings of organs and blood vessels. As the ...

The discovery of Comet SWAN by solar-watcher SOHO

Currently crossing the skies above Earth, Comet C/2020 F8 (SWAN) has the potential to become a more prominent naked eye object by late May or early June. Yet it wasn't discovered by someone looking up at the night sky. Instead, ...

Unraveling the magnetism of a graphene triangular flake

Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene is predicted to be magnetic. This apparent contradiction is a consequence of "magic" shapes in the structure ...
