Every 8.5 years the Earth's core wobbles, resulting in a mysterious ‘signal.’ A new study attempts to explain this geophysical mystery.

In 2019, scientists detected strange signals coming from deep below the Earth's surface that oscillate roughly every 8.5 years. Now, by mapping minute changes in the Earth's rotation, the team has come up with an explanation: our planet's inner core may actually be at an angle in relation to the mantle. This mysterious "Inner […]

Strange variations across different measurements of the planet's surface have revealed periodic oscillations deep in Earth's heart.

Researchers from the University of Hong Kong developed an AI algorithm that uses 3D machine learning to design personalized dental crowns with a higher degree of accuracy than traditional methods.

The team, led by Dr James Tsoi, Associate Professor in Dental Materials Science collaborated with colleagues from HKU Faculty of Engineering’s Department of Computer Science to take a leap forward for the next-generation AI-designed dental prosthesis production workflow. The researchers developed a generative AI algorithm that uses a true three-dimensional (3D) deep learning approach, producing personalised dental crowns with high accuracy that mimic the morphology and match the materials required for the biomechanics of natural teeth. Biomechanical finite element analysis revealed that by u...
