Tartar in the mouths of 1,000-year-old monk skulls are a storehouse of information about past, and possibly also present-day, diseases. Analyses of the tartar indicate that humans were resistant to antibiotics 1,000 years ago.

The mystery of why massive galaxies existed in the early universe may now have been solved. New research shows that the galaxies were formed as a result of a collision of galaxies and the subsequent explosive formation of stars.
The recent discovery of a millisecond pulsar orbited by two white dwarfs challenges current theories of their formation. A new semi-analytical model may help explain the formation of this unique triple system.
