A 1,900-year-old latrine is the latest source of insight into Roman concrete's longevity. Researchers found that carbonation seals cracks, enabling self-healing, a mechanism that could inspire modern materials.

Roman concrete and Maya astronomers steal the day
Today's history coverage is dominated by two threads: the enduring mystery of Roman concrete gets a fresh clue from a latrine, and Maya astronomy gains its first named individual. Both stories shift what we thought we knew about ancient engineering and science.
Ancient materials and methods
Two stories today challenge assumptions about ancient technology and physical activity.
Bone analysis of mummified Egyptian princesses from 3,800 years ago shows they likely used bows and daggers actively, not just as burial ornaments. The evidence challenges assumptions about royal women's roles.
Names and signatures
A rare direct link to a named Maya astronomer and a forensic ID of Philip II highlight how individual identities are emerging from the past.

For the first time, archaeologists have identified a named Maya astronomer, an eighth-century mathematician whose signature was found alongside calendar formulas at Xultun. It's a rare direct link to an individual in Maya science.

King Philip II of Macedon's remains have been conclusively identified by a lance wound to the knee, matching ancient accounts. The forensic evidence solves a decades-old debate over which tomb in Vergina holds Alexander the Great's father.
Lost and found
Rediscovered negatives and an accidental cave find show how history can resurface in unexpected ways.
Frank Hurley saved glass-plate negatives from Shackleton's sinking Endurance in 1915, defying orders to abandon them. A new book of the rescued images is revealing fresh details about the expedition.
A family holiday led to the accidental discovery of a large archaeological cave beneath a UK castle. Researchers say the undisturbed calcite floor suggests high potential for rewriting local history.
