The mobile application enables contributors to document unusual specimens ranging from Malaysian baobabs to Scotland's estimated 5,000-year-old Fortingall yew. Conceived during visits to Lisbon, the platform is now preparing to introduce urban walking routes that link significant trees in metropolitan areas. Dendrologist Dan Crowley emphasized that regular community observations through changing seasons provide valuable support for conservation, especially as hot and dry weather strains tree health.

While most people spend their holidays sightseeing or lazing by a pool, Hidde Burgmans would rather seek out special trees.
While not an expert in the subject, the 37-year-old from Baarn in the Netherlands has developed what he cheerfully admits is something of an obsession. He even managed to propose to his girlfriend, Nadia Roeleveld, under a particularly special cedar in Japan: “My fiancee always laughs, because she’s like, ‘OK, we have to make a detour again because Hidde found another big tree’.”
Burgmans is the creator of Ancient Trees, an app that maps remarkable old trees around the world and shows users which specimens are nearby. Users upload their favourites, along with photos and descriptions, and add the ones they visit to their profile. Trees featured range from Malaysian baobabs to the Fortingall yew in Perthshire, Scotland, which is thought to be about 5,000 years old.
The idea for the app took root on work trips to Lisbon. With time to kill between meetings, Burgmans wandered through the city’s parks and found himself among century-old jacarandas and wild figs.…
Researchers addressed reflection-driven energy loss in photovoltaic hardware by creating three-dimensional, concave modules that capture bouncing photons across varying angles. This geometric adaptation eliminates reliance on complex mechanical tracking systems to follow the sun. By pairing the design with pliable materials, developers opened new possibilities for integrating solar technology directly into non-flat infrastructure.
Alice Huang, described as a "Chinese spy," left the company Megaspeed in 2025 amid an ongoing row involving Nvidia. Following the development, Megaspeed stated that it conducted "legitimate and lawful business."
The regional Nvidia cloud computing partner is navigating severe geopolitical scrutiny after U.S. intelligence linked a former top shareholder to Chinese intelligence collection efforts. These allegations culminated in the resignation of Nvidia's chief executive and sparked inquiries into whether advanced chip infrastructure was improperly accessed. The company maintains full compliance with export controls while working to dispel allegations of unauthorized technology diversion.
