An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics in a two-dimensional analog quantum simulator for the first time. The study, published in Nature, opens up new possibilities for research into fundamental physical phenomena.

String breaking occurs when the string between two strongly bound particles, such as a quark-antiquark pair, breaks and new particles are created. This concept is central to understanding the that occur in (QCD), the theory that describes the binding of quarks in protons and neutrons.

String breaking is extremely difficult to observe experimentally, as it only occurs in nature under extreme conditions. The recent work by scientists from the Universities of Innsbruck and Harvard, the ÖAW-Institute for Quantum Optics and Quantum Information (IQOQI) and the quantum computer company QuEra shows for the first time how this phenomenon can be reproduced in an analog quantum .

The entry of quantum computers into society is currently hindered by their sensitivity to disturbances in the environment. Researchers from Chalmers University of Technology in Sweden, and Aalto University and the University of Helsinki in Finland, now present a new type of exotic quantum material, and a method that uses magnetism to create stability.

This breakthrough can make quantum computers significantly more resilient—paving the way for them to be robust enough to tackle quantum calculations in practice.

The paper, “Topological Zero Modes and Correlation Pumping in an Engineered Kondo Lattice,” is published in Physical Review Letters.

A team at EPFL and the University of Arizona has discovered that making molecules bigger and more flexible can actually extend the life of quantum charge flow, a finding that could help shape the future of quantum technologies and chemical control. Their study is published in the Proceedings of the National Academy of Sciences.

In the emerging field of attochemistry, scientists use to trigger and steer electron motion inside . This degree of precision could one day let us design chemicals on demand. Attochemistry could also enable real-time control over how break or form, lead to the creation of highly targeted drugs, develop new materials with tailor-made properties, and improve technologies like solar energy harvesting and quantum computing.

But the big roadblock is decoherence: Electrons lose their quantum “sync” within a few femtoseconds (a millionth of a billionth of a second), especially when the molecule is large and floppy. Researchers have tried different methods to sustain coherence—using heavy atoms, freezing temperatures etc. Because quantum coherence vanishes at macroscopic scales, most approaches to sustaining coherence operate on the same assumption: larger and more flexible molecules were assumed to lose coherence more rapidly. What if that assumption is wrong?

Imagine getting a tattoo… that can track your health, location, or identity — and you don’t even need a device. Sounds like sci-fi? It’s real. Scientists have developed futuristic electronic tattoos that use special ink to monitor your body in real-time — from heart rate to hydration — and even transmit data without chips or batteries. But here’s the catch… could this breakthrough be the future of medicine? Or is it a step too close to surveillance under your skin?

Let’s explore how these tattoos work, what they can really do, and the wild implications they might have for your health — and your privacy.

Scientists in Germany have achieved a world first by moving individual atoms from one position to a precisely defined final one using magnetism, unlocking the potential for controlled atomic motion in nanotechnology and data storage.

The research team from the University of Kiel (CAU) and the University of Hamburg used a highly sensitive scanning tunneling microscope (STM) to manipulate atoms on a specially engineered magnetic surface.

Scientists at the University of Surrey have made a breakthrough in eco-friendly batteries that not only store more energy but could also help tackle greenhouse gas emissions. Lithium-CO₂ ‘breathing’ batteries release power while capturing carbon dioxide, offering a greener alternative that may one day outperform today’s lithium-ion batteries.

Until now, Lithium-CO₂ batteries have faced setbacks in efficiency — wearing out quickly, failing to recharge and relying on expensive rare materials such as platinum. However, researchers from Surrey have found a way to overcome these issues by using a low-cost catalyst called caesium phosphomolybdate (CPM). Using computer modelling and lab experiments, tests showed this simple change allowed the battery to store significantly more energy, charge with far less power and run for over 100 cycles.

The study, published in Advanced Science, marks a promising step toward real-world applications. If commercialised, these batteries could help cut emissions from vehicles and industrial sources — and scientists even imagine they could operate on Mars, where the atmosphere is 95% CO₂

Recent technological advances have enabled the development of a wide range of increasingly sophisticated wearable and implantable devices, which can be used to monitor physiological signals or intervene with high precision in therapeutically targeted regions of the body. As these devices, particularly implantable ones, are typically designed to remain in changing biological environments for long periods of time, they should be biocompatible and capable of fixing themselves after they are damaged.

Researchers at Sungkyunkwan University, the Institute for Basic Science (IBS) and other institutes in South Korea recently devised a new method to fabricate self-healing and stretchable electronic components that could be integrated into these devices. Their approach, outlined in a paper published in Nature Electronics, enables the scalable and reconfigurable assembly of self-healing and stretchable transistors into highly performing integrated systems.

“Since the mid-2000s, the development of flexible and has significantly revolutionized research fields such as artificial electronic skin and soft implantable bioelectronics,” Donghee Son, senior author of the paper, told Tech Xplore.
