Carvings made over decades by Basque herders are endangered as their canvas, the aspens, are at risk. Sawtooth Mountains, 2011, Idaho Basque Arborglyphs Collection, Special Collections and Archives, Albertsons Library, Boise State University

Arborglyphs – Basque immigrant sheepherders left their marks on aspen trees in the American West

Herders carved names, slogans, nude silhouettes and more into the trees around them during lonely seasons in the mountains. Now, researchers rush to find and record the arborglyphs before they disappear.

3D scanning: we recreated a sacred South African site in a way that captures its spirit

One criticism of current 3D models of archaeological sites is that they are presented devoid of human traces and history.

Cultural heritage and historic preservation: creating a digital twin of Shahjahanabad

Once the capital of the Mughal empire, Old Delhi is now under threat. Geo-information technology can reveal its previous form, function, and context, however, and so help preserve and bring it back to life.

DALL-E 2 and Midjourney can be a boon for industrial designers

During the brainstorming stage of the design process, AI-powered image generation programs can open creative doors that may have otherwise never been accessed.

How virtual 3D modelling and simulation can help us create better cities

3D urban modelling is a transformative technology for designing cities. But incorporating new technologies into planning practice has its challenges.
Fossilized teeth from a modern human who lived in Israel close to 200,000 years ago. Israel Hershkovitz, Tel Aviv University

Fossil jawbone from Israel is the oldest modern human found outside Africa

New discoveries are changing archaeologists’ ideas about the origins of our own species and our migration out of Africa. This fossil pushes Homo sapiens’ African exodus date back by 50,000 years.

Can you be hacked by the world around you?

Scanning physical items constructed with nefarious intent can introduce malware into a smartphone or computer.

3D technology brings a lost mammalian ancestor back to life

An old technique to explore the inside of fossils unfortunately ended up destroying some unique specimens. New technology has been used to reconstruct one such fossil.
