Scientists have shown in the laboratory that metal nanoparticles damaged the DNA in cells on the other side of a cellular barrier. The nanoparticles did not cause the damage by passing through the barrier, but generated signalling molecules within the barrier cells that were then transmitted to cause damage in cells the other side of [...]

A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist.
The team has obtained extremely precise data about the early universe, using a telescope near the South Pole in the Antarctic.
