A scratched wooden door found by chance at the top of a medieval turret has been revealed to be an "astonishing" graffiti-covered relic from the French revolutionary wars, including a carving that could be a fantasy of Napoleon Bonaparte being hanged.

Over 50 individual graffiti carvings were chiselled into the door in the 1790s by bored English soldiers stationed at Dover Castle in Kent, when Britain was at war with France in the wake of the French Revolution. They include a detailed carving of a sailing ship, an elaborate stylised cross and nine individual scenes of figures being hanged – one of whom is wearing a bicorn hat. The simple plank door was first discovered several years ago at the top of St John's tower, which for more than a century had been impossible to access without climbing a ladder to the base of a spiral staircase. At the time, however, it was covered in thick layers of paint that obscured many of its markings.

A Northland island (in Aotearoa/New Zealand) has a very unusual (but good) problem...too many kiwi. Residents on Moturoa, in Ipipiri, have been forced to relocate the reclusive birds after their population swelled into the hundreds. (This was the result of a local program to control feral predators like cats and foxes - in most parts of New Zealand, kiwi are under threat.)

Koala briefly runs through a triathlon.

Runners in this year's Ironman Australia triathlon at Port Macquarie got a surprise as they made their way through the challenging final leg on the New South Wales Mid North Coast. A male koala, known to inhabit the area, made its way straight across the course in front of runners and towards a gum tree. The moment was captured on camera by local resident Jason Hannah, who lives near the triathlon course.

On a patch of earth big as a Bunnings car park, renters get to join in on the solar boom. A five-hour drive from Sydney, a community garden of sorts has sprouted. But instead of sharing tomatoes or lettuce, "gardeners" harvest solar energy. And it's already a hit with people otherwise excluded from the rooftop solar boom.

Tasmanian devil tooth found during archaeological dig 1000 kilometres north of Perth. The tooth could provide further historical evidence of inter-community trading in Western Australia and was unearthed in Juukan Gorge, which made headlines in 2020 when its rock shelters were damaged by Rio Tinto blasts. "There is no physical evidence that [Tasmanian devils] ever lived in the Pilbara, and the last evidence of devils living in Western Australia was in the South West around 3000 years ago," he said.

Sumatran orangutan becomes first wild animal seen using medicinal plant to treat wound.

A Sumatran orangutan has become the first wild animal seen self-medicating with a plant to heal a wound. The male orangutan, named Rakus, had sustained a wound on his cheek pad, most likely from fighting other males, researchers said in a study published in the journal Scientific Reports. Rakus was seen chewing liana leaves without swallowing them, then using his fingers to apply the resulting juice onto the wound, the researchers said. Finally, he covered the wound up completely with a paste he had made by chewing the leaves and continued feeding on the plant. Five days after he was seen applying the leaf paste onto the wound it was closed, and a month later barely visible. It is the first documented case of active wound treatment by a wild animal with a plant known to have medicinal qualities. The leaves were from a liana known as akar kuning (Fibraurea tinctoria in Latin), which is used in traditional medicine to relieve pain, reduce fever and treat various diseases, such as diabetes and malaria. It also has antibacterial, anti-inflammatory, antifungal and antioxidant properties.
