In a new study, an international team of physicists has unified two distinct descriptions of atomic nuclei, taking a major step forward in our understanding of nuclear structure and strong interactions. For the first time, the particle physics perspective – where nuclei are seen as made up of quarks and gluons – has been combined with the traditional nuclear physics view that treats nuclei as collections of interacting nucleons (protons and neutrons). This innovative hybrid approach provides fresh insights into short-range correlated (SRC) nucleon pairs – which are fleeting interactions where two nucleons come exceptionally close and engage in strong interactions for mere femtoseconds. Although these interactions play a crucial role in the structure of nuclei, they have been notoriously difficult to describe theoretically.

“Nuclei (such as gold and lead) are not just a ‘bag of non-interacting protons and neutrons’,” explains Fredrick Olness at Southern Methodist University in the US, who is part of the international team. “When we put 208 protons and neutrons together to make a lead nucleus, they interact via the strong interaction force with their nearest neighbours; specifically, those neighbours within a ‘short range.’ These short-range interactions/correlations modify the composition of the nucleus and are a manifestation of the strong interaction force. An improved understanding of these correlations can provide new insights into both the properties of nuclei and the strong interaction force.”

This in-depth analysis explores the implications of artificial superintelligence and why we must act now to ensure its development benefits humanity.

Anirban Datta, Head of Discovery Biology at Verseon International Corporation, details how recent breakthroughs are bringing once-distant possibilities, such as testing drugs more efficiently and restoring lost organ function through implantation, closer to reality.

Imagine being able to create an in vitro replica of a diseased organ to study the molecular mechanism underlying the illness. Now take a step further: envision testing drugs in these organoids to identify the ones that can treat disease safely and effectively without needing to run expensive clinical trials first. Further still, think about implanting these mini organs into the patient to restore lost function. With multiple breakthroughs in recent decades, these goals are now much closer to reality.

👁️🔍 Scientists have developed a transparent camera using see-through technology, paving the way for hidden eye tracking devices in everyday objects. #InvisibleInnovation

The problem is that placing a camera in front of the eyes tends to block the view. And mounting them further away makes them less accurate, more bulky and often more power hungry because of the extra data processing they require. This has limited their utility in many situations.

What eye trackers need is a way of hiding light sensitive pixels in plain sight.

Researchers have developed a cutting-edge optical computing system that represents a major leap in the field of optical logic.

Traditionally, optical logic computing—using light to perform logical operations—has faced challenges when trying to handle more than four inputs due to limitations in…

Researchers have long sought to harness the power of light for computing, aiming to achieve higher speeds and lower energy consumption compared to traditional electronic systems. Optical computing, which uses light instead of electricity to perform calculations, promises significant advantages, including high parallelism and efficiency. However, implementing complex logic operations optically has been a challenge, limiting the practical applications of optical computing.

New research from the University of Göttingen reveals that amethyst geodes in Uruguay formed at low temperatures from groundwater-like fluids, proposing a new model for their formation based on extensive geological surveys and innovative analytical methods.

Amethyst, the violet variety of quartz, has been used as a gemstone for centuries and is a key economic resource in northern Uruguay. Geodes are hollow rock formations often with quartz crystals, such as amethyst, inside.

In Uruguay, amethyst geodes have been found in cooled lava flows dating back to the original breakup of the supercontinent Gondwana approximately 134 million years ago. However, their formation has remained a mystery.

A recent breakthrough in frequency conversion has achieved substantial bandwidth, opening new possibilities for more efficient quantum information transfer and advanced integrated photonic systems.

Advancements in quantum information technology are enabling faster and more efficient data transfer. A major challenge, however, lies in transferring qubits—the fundamental units of quantum information—across different wavelengths while preserving their crucial properties, such as coherence and entanglement.

As reported in Advanced Photonics, researchers from Shanghai Jiao Tong University (SJTU) recently made significant strides in this area by developing a novel method for broadband frequency conversion, a crucial step for future quantum networks.

A new camera system is making it possible for humans to see colors in the way animals do, opening up a vivid new perspective on the natural world.

Led by researcher Vera Vasas, who has spent years studying animal vision, this innovative project is changing how we understand what animals actually see.

In collaboration with colleagues from the Hanley Color Lab at George Mason University, Vasas has developed a tool that lets us experience the world through the eyes of different species.
