A 38 million-year-old piece of amber containing a pair of Electrotermes affinis termites has provided insight into the mating behavior of these long-extinct insects. The fossilized termites were found in a side-by-side position, suggesting they were likely engaged in tandem running, a common mating behavior in living termites. Researchers used 3D imaging to identify the male and female termites and recreated their final moments in a lab with living termites to understand how they got trapped in the resin. This discovery sheds light on the ancient behavior of termites and provides a rare glimpse into their mating rituals.

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf have successfully visualized a detailed three-dimensional image of turbulent temperature-driven liquid metal flow using a self-developed method called contactless inductive flow tomography (CIFT). This breakthrough could provide insights into geophysical and astrophysical flow phenomena and industrial applications, such as the casting of liquid steel. The team overcame challenges in measuring the small flow-induced magnetic fields and aims to further develop the measurement method for increased accuracy and deeper insights into turbulent liquid metal flows.

A new method developed by the University of Bonn and University of Bristol allows for the precise measurement of all three spatial coordinates of individual atoms with one single image, using an effect known in theory since the 1990s. This method, based on quantum gas microscopy, deforms the wavefront of light emitted by the atom, producing a dumbbell shape on the camera that rotates around itself, allowing researchers to determine the z coordinate. This breakthrough is important for quantum mechanics experiments and could aid in the development of new quantum materials with special characteristics.

Scientists have developed a new compact facial recognition system that uses flatter, simpler optics and requires less energy than existing 3D imaging systems in smartphones. The system, tested on a replica of Michelangelo's David, employs metasurfaces and a photonic crystal surface-emitting laser to generate customizable and versatile light patterns, making it more energy-efficient and suitable for integration into a single chip. The new system recognized the face as well as existing smartphone facial recognition while using 5-10 times less power.

Scientists have developed a new method of analyzing deep-sea creatures using 3-D imaging systems and an origami-inspired collecting device with built-in tissue sampling and preservation, allowing them to study marine life in its natural environment. This approach has the potential to accelerate the pace of new species discovery and description in the ocean, without the need to bring physical specimens to the surface. The method was successfully tested during two research cruises off the coasts of Hawaii and San Diego, where scientists interacted with various deep-sea organisms, including the gossamer worm. The goal is to further refine the technology to enable minimally invasive biopsies and DNA swabbing of deep-sea creatures, providing a gentle "checkup" for these delicate organisms.

AI and 3D imaging have revealed that the surface of each person's tongue, with its unique papillae patterns, is distinct. By analyzing over two thousand detailed scans from fifteen individuals, AI models were able to predict personal characteristics such as age and gender with up to 85% accuracy based on tongue features. This breakthrough has implications for personalized food development, early oral cancer diagnosis, and a deeper understanding of taste and touch variations. The research highlights the intricate biological uniqueness of the human tongue and opens doors to numerous health and culinary applications.
