The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena—such as the behavior of individual electrons in an atom. But combining the two in a completely satisfactory way has yet to be achieved. The search for a “quantum theory of gravity” is considered one of the significant unsolved tasks of science.

This is partly because the mathematics in this field is highly complicated...

Imagine a scenario where you simply just throw a pill in a liquid to identify a problem—this is now one step closer to reality thanks to the work done by researchers at Fraunhofer IZM in cooperation with Micro Systems Technologies (MST) and Sensry GmbH. As small as a piece of candy, the waterproof IoT sensor can reliably measure the properties of liquids even in hard-to-reach places. This can make the maintenance of industrial machines much easier and even help to identify diseases.

The larger an industrial machine, the more difficult it is to troubleshoot malfunctions by detecting unwanted oil pressure deviations or even line leaks from the outs...

Minimally invasive surgery and automated robot-guided surgery are likely to be performed under extreme conditions, which require new demands on intraoperative information acquisition capabilities. Three-dimensional (3D) brain point cloud generation plays an essential role in overcoming the visual limitations of these surgeries.

One of the applications of generative AI is in the field of 3D brain point cloud generation. By using deeplearning algorithms, the 3D point cloud of the patient’s brain can be generated for reconstruction during minimally invasive surgery. However, some conventional existing point cloud reconstruction methods still have limitations when applied directly to real surgical scenarios.

Now, a research team led by Prof...
