Archaeologists in Poland have uncovered the skeleton of a child from the 17th century in a graveyard near Dąbrowa Chełmińska. The body was interred face down, and a small triangular padlock was placed beneath the foot bones. Researchers interpret the unusual position and the lock as deliberate measures connected to local burial customs intended to prevent the deceased from returning to harm the living.

The British Museum is dealing with a major internal crisis after allegations that a senior curator removed and sold roughly 2,000 items from its collection via eBay. Reports say the revelations prompted the museum director to resign and have led to calls for an independent review. The case has drawn attention to weaknesses in oversight and controls at one of the world’s largest museums, raising questions about how objects are tracked and safeguarded.
