Researchers at TU Wien have developed a novel method to grow replacement tissue, such as cartilage, in the lab using a unique high-resolution 3D printing process that creates porous spheres for cell colonization. This technique allows for the assembly of these spheres into any shape, with cells combining to form a uniform, living tissue, overcoming previous challenges in controlling tissue shape and integration.TU Wien has pioneered a novel method for generating artificial tissue: Cells are grown in microstructures…

Researchers have successfully altered magnetism in a crystal by applying pressure. This method, which varies the magnetic interactions in a crystal lattice, could revolutionize data storage and quantum computing by controlling geometrical frustration and magnetic properties.Magnetism is influenced by the behavior of electrons. For instance, these tiny particles can create an electric current using their charge, which in turn can produce a magnetic field. Additionally, magnetism can emerge from the coordinated alignment of…

Emission of a single photon in the Maxwell fish-eye lens. Credit: Oliver Diekmann (TU Wien)Scientists have developed “quantum ping-pong”: Using a special lens, two atoms can be made to bounce a single photon back and forth with high precision.Atoms can absorb and reemit light — this is an everyday phenomenon. In most cases, however, an atom emits a light particle in all possible directions — recapturing this photon is therefore quite hard.A research team from TU Wien in Vienna (Austria) has now been able to demonstrate…

Quantum computers require precise time measurement for manipulating quantum states, but new research has revealed a fundamental limitation: clocks cannot achieve perfect resolution and precision simultaneously due to their finite energy and entropy generation. This imposes inherent constraints on quantum computing’s capabilities. As quantum technology advances, overcoming these time measurement challenges will become critical, possibly leading to new discoveries in quantum mechanics.Quantum computing is becoming more…

Recent research has uncovered that the persistent radioactive contamination in Central Europe’s wild boar meat, a result of the Chernobyl disaster, is also significantly influenced by cesium from 1960s nuclear weapons tests, highlighting complex ecological interactions and the crucial role of precise scientific analysis. Credit: Joachim Reddermann / TU Wien Decades following the Chernobyl nuclear disaster, wild boar meat continues to exhibit unexpectedly high levels of radioactivity. The solution to the riddle: an…
