Digital Preservation of the Endangered Vaquita

Researchers from Florida Atlantic University have created one of the most detailed digital records ever made of the vaquita (Phocoena sinus), the world’s most endangered marine mammal. Using medical CT scans, high-resolution micro-CT imaging, and digital photography, the team digitized a rare female vaquita skeleton collected in 1966, transforming it into interactive 3D models that can be explored, measured, and studied without risking damage to the fragile original specimen. The resulting datasets have been made freely available through the MorphoSource repository.

The project serves as both a scientific resource and a conservation effort for a species on the brink of extinction. Found only in Mexico’s northern Gulf of California, the vaquita has suffered a catastrophic population decline due to accidental entanglement in illegal gillnets used to catch totoaba fish. With only a handful of individuals believed to remain in the wild, the digital archive preserves invaluable anatomical information for future generations while raising awareness of the urgent need for international action to eliminate gillnet fishing and protect this critically endangered porpoise.

MIT Unveils Virtual Violin Design Tool

Researchers at MIT have developed a physics-based virtual violin that could transform how violins are designed and tested. Unlike conventional digital sound simulators that rely on prerecorded samples, the new computational model recreates the actual physical behavior of the instrument, allowing it to generate realistic violin sounds by simulating how strings, wood, and surrounding air interact. The system enables luthiers to experiment with factors such as wood type, plate thickness, and structural geometry before physically building an instrument.

The project aims to provide violin makers with a scientific design tool that complements centuries of artisan knowledge. Researchers believe the model could accelerate experimentation and offer new insights into the acoustics behind legendary instruments such as Stradivari violins. While the current system focuses on reproducing plucked-string sounds, future versions may simulate bowed performance as well, potentially opening new possibilities for digital instrument design, acoustic research, and preservation of historical instrument-making traditions.

Realistic Human Hand 3D-Printed from a Single Material

Researchers at the University of Texas at Austin, working with Sandia National Laboratories, have developed a novel 3D printing method called CRAFT (Crystallinity Regulation in Additive Fabrication of Thermoplastics) that lets a single inexpensive material be tuned at the pixel level to produce different mechanical and optical properties within one object. By precisely controlling light intensity during printing, CRAFT can make parts of an object hard and transparent while adjacent regions stay soft and flexible, mimicking the variety of textures found in real human tissues like skin, ligaments, tendons and bone.

Using this technique with a standard affordable 3D printer, the team successfully printed a realistic model of a human hand from one feedstock that captures these varying properties without needing multiple materials. This innovation could have significant practical applications, especially in medical training and education. Because traditional cadavers are costly, ethically complex to source, and don’t reflect the feel of real human tissue, CRAFT-printed models could offer a cheaper, more realistic alternative for students to practice on. Beyond medical use, the process may also be applied to making bioinspired materials for things like impact-absorbing gear or soundproofing.

3D map Covering 2.75 Billion Buildings

Scientists at Technical University of Munich (TUM) have unveiled GlobalBuildingAtlas, the first global, high-resolution 3D map of Earth’s man-made environment. The atlas covers about 2.75 billion buildings around the world, using satellite imagery from 2019 and offering a resolution roughly 30 times finer than previous global building maps. 

Each structure is represented at a fine resolution of about 3 × 3 meters, enough to estimate building height, volume, and density. Around 97% of the buildings are modelled as simplified 3D LoD1 geometries, not highly detailed, but sufficient for large-scale computational modelling.

Gradient 3D Printed Designs

A new open-source software is shaking up the way engineers design and print multi-material objects. Created in the Matter Assembly Computation Lab, the tool enables engineers to design spatially varying multi-material objects with remarkable ease and precision.

The project reflects a growing interest in computational approaches that merge coding with design. The software allows users to combine complex mathematical functions and assign them as materials to different regions of a 3D object.

Forest Digital Twin

Scanning forests with lasers can provide three-dimensional models of forests, creating a unique way to look at these ecosystems. Researchers at the University of Helsinki are pioneers in applying this technical solution to measuring ecosystems. This technique, referred to as Terrestrial laser scanning (TLS), opens new opportunities in measuring forest structure, monitoring disturbances and simulating ecosystems.

TLS provides us with a new way of looking at forests – not just from above, but from within. It helps us understand tree growth, forest responses to disturbances and the effects of forest structure on biodiversity and capacity for recovery. A deeper understanding helps researchers, decision-makers and communities to make increasingly justified decisions – and, ultimately, to better reconcile human activity with the environment.

Interactive Media for Cultural Heritage

Recently, the latest edited book I co-authored with colleagues from CYENS – Centre of Excellence and the University of Cyprus was published by Springer Series on Cultural Computing. The book is entitled ‘Interactive Media for Cultural Heritage’ and presents the full range of interactive media technologies and their applications in Digital Cultural Heritage. It offers a forum for interaction and collaboration among the interactive media and cultural heritage research communities.

The aim of this book is to provide a point of reference for the latest advancements in the different fields of interactive media applied in Digital Cultural Heritage research, ranging from visual data acquisition, classification, analysis and synthesis, 3D modelling and reconstruction, to new forms of interactive media presentation, visualization and immersive experience provision via extended reality, collaborative spaces, serious games and digital storytelling.

3D Face Scanning From Far

Researchers at Heriot-Watt University in Scotland and his colleagues built a device that can create detailed three-dimensional images, including ridges and indentations as small as 1 millimetre, from hundreds of metres away. It uses an imaging technique called lidar, emitting pulses of laser light that collide with objects then reflect back into the device. Based on how long each pulse takes to return, lidar can determine an object’s shape. The team had to calibrate and align many different components.

To enable it to distinguish single particles of light, the researchers used a light-detecting sensor based on an incredibly thin piece of superconducting wire, a component that isn’t common in lidar. Filtering out sunlight that could enter the detector and degrade the image was another challenge. The researchers tested their lidar system on a roof near their lab by taking detailed three-dimensional images of a team member’s head from 45 and 325 metres away. On a smaller scale, they captured Lego figurines from a distance of 32 metres.
