Breaking Physics: How Solitons Bend Time, Space, and Rules

Posted by in categories: biotech/medical, robotics/AI

If it walks like a particle, and talks like a particle… it may still not be a particle. A topological soliton is a special type of wave or dislocation that behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. In a new study published in Nature, researchers from the University of Amsterdam demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings, and communicate.

Topological solitons can be found in many places and at many different length scales. For example, they take the form of kinks in coiled telephone cords and large molecules such as proteins. At a very different scale, a black hole can be understood as a topological soliton in the fabric of spacetime. Solitons play an important role in biological systems, being relevant for protein folding and morphogenesis – the development of cells or organs.

Pushing back the limits of optical imaging by processing trillions of frames per second

Posted by in category: futurism

Pushing for a higher speed isn’t just for athletes. Researchers, too, can achieve such feats with their discoveries. This is the case for Jinyang Liang, Professor at the Institut national de la recherche scientifique (INRS), and his team, whose research results have recently been published in Nature Communications.

Scientists Propose New Theory that explains Sand Ripples on Mars and on Earth

Posted by in category: space

Sand ripples are fascinating. They are symmetrical, yet wind — which causes them — is very much not. Furthermore, they can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on two different planets of our solar system?

That is what Ben-Gurion University of the Negev physicist Prof.

Hezi Yizhaq and Prof. Itzhak Katra and their colleagues from Denmark, Germany, Italy, China, and the US contend in a cover article published in Nature Geoscience.

New AI Technology enables 3D Capture and Editing of Real-Life Objects

Posted by in categories: mobile phones, robotics/AI

Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle. This is fast becoming reality, thanks to advances in AI.

Researchers at Simon Fraser University (SFU) in Canada have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.

In a new paper appearing on the arXiv preprint server and presented at the 2023 Conference on Neural Information Processing Systems (NeurIPS) in New Orleans, Louisiana, researchers demonstrated a new technique called Proximity Attention Point Rendering (PAPR) that can turn a set of 2D photos of an object into a cloud of 3D points that represents the object’s shape and appearance.

Why does life flash before your eyes in a life-threatening scenario?

Posted by in category: futurism

But what explains this phenomenon? Psychologists have proposed a number of explanations, but I’d argue the key to understanding Tony’s experience lies in a different interpretation of time itself.
