Emergence of solvated dielectrons observed for the first time
Team in conjunction with the University of Freiburg generates low-energy electrons using ultraviolet light Solvated dielectrons are the subject of many hypotheses among scientists, but have never been directly observed. They are described as a pair of electrons that is dissolved in liquids such as water or liquid ammonia.

Scepticism about Microsoft results
In March 2022, Microsoft published research results about the realisation of a special type of particle that might be used to make particularly robust quantum bits. Researchers at the University of Basel are now calling these results about so-called Majorana particles into doubt: through calculations they have shown that the findings can also be explained differently.

Bird brains can flick switch to perceive Earth’s magnetic field  
Understanding how animals make their way around in the world helps determine things humans are doing that might influence them Earth's magnetic field, generated by the flow of molten iron in the planet's inner core, extends out into space and protects us from cosmic radiation emitted by the Sun. It is also, remarkably, used by animals like salmon, sea turtles and migratory birds for navigation.

Scientists propose revolution in complex systems modelling with quantum technologies
Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly reduced memory. Complex systems play a vital role in our daily lives, whether that be predicting traffic patterns, weather forecasts, or understanding financial markets.

Physicists to Listen Closely to Black Holes Ring
Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet Earth rolls around the sun like a marble tossed into a funnel (Earth does not fall into the sun due to the Earth's sideways momentum).

Making the structure of ’fire ice’ with nanoparticles
The structure harnesses a strange physical phenomenon and could enable engineers to manipulate light in new ways Study: Entropy compartmentalization stabilizes open host-guest colloidal Clathrates. (DOI: 10.1038/s41557'023 -01200-6) Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers at the University of Michigan have shown how to achieve this through computer simulations.

New production process for therapeutic nanovesicles
Researchers at the University of Basel have developed an efficient method for the preparation of therapeutic nanovesicles, thereby fulfilling a key prerequisite for industrial production. The method also paves the way for research into areas such as immunotherapy treatments for cancer. Particles known as extracellular vesicles play a vital role in communication between cells and in many cell functions.

Watching Molecules Relax in Real Time
Designing the next generation of efficient energy conversion devices for powering our electronics and heating our homes requires a detailed understanding of how molecules move and vibrate while undergoing light-induced chemical reactions. Researchers at the Department of Energy's Lawrence Berkeley National Laboratory ÜBerkeley Lab) have now visualized the distortions of chemical bonds in a methane molecule after it absorbs light, loses an electron, and then relaxes.

By adjusting knob to the quantum solid
Quantum physicists at the University of Innsbruck, together with colleagues at the ETH Lausanne, have found a new way to generate a crystalline structure that emerges as a "coherent matter density wave" in an atomic gas. The findings help to better understand the fascinating behavior of quantum matter near absolute zero.

University of Glasgow researchers prepare for next gravitational wave observing run
Researchers from the University of Glasgow's School of Physics & Astronomy are preparing for the next observing run of the international LIGO-Virgo-KAGRA (LVK) network of gravitational-wave detectors. The LVK collaboration consists of scientists across the globe who use a network of observatories-LIGO in the United States, Virgo in Europe, and KAGRA in Japan-to search for gravitational waves, or ripples in space-time, generated by colliding black holes and other extreme cosmic events.

A better way to match 3D volumes
By mapping the volumes of objects, rather than their surfaces, a new technique could yield solutions to computer graphics problems in animation and CAD. In computer graphics and computer-aided design (CAD), 3D objects are often represented by the contours of their outer surfaces. Computers store these shapes as "thin shells," which model the contours of the skin of an animated character but not the flesh underneath.

Explosion in the Night Sky - First Brightness Measurements of Supernova SN2023ixf
Astronomers at the University of Potsdam have succeeded in making one of the world's first brightness measurements of the supernova SN2023ixf in the constellation Ursa Major, which was discovered only on Friday evening. It is the brightest detected outburst in more than ten years in the galaxy Messier 101.

ToCoTronics Extended
The Collaborative Research Centre ToCoTronics in condensed matter physics will be extended for four more years. The German Research Foundation is funding it with 12 million euros. Topological materials are intensively investigated in the world. This boom started at Julius-Maximilians-Universität (JMU) Würzburg, where the physics professor Laurens Molenkamp realized the first topological insulator in 2007.

Fusion Q&A: The Path Forward
Fusion is one of the biggest challenges of our time. The same process that powers our sun could provide a near limitless supply of safe and carbon-free energy - if researchers can overcome the technological hurdles. The Department of Energy's Lawrence Berkeley National Laboratory ÜBerkeley Lab) has a deep history with both of the main approaches to fusion , where nuclei join together and release energy.

’Hightech’ materials from nature
Research team at Göttingen University discovers surprising properties of the cytoskeleton Most biological cells have a fixed place in an organism. However, cells can become mobile and move through the body. This happens, for example, during wound healing or when tumour cells divide uncontrollably and migrate through the body.

Curved spacetime in a quantum simulator
New techniques can answer questions that were previously inaccessible experimentally - including questions about the relationship between quantum mechanics and relativity. The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide.

JUICE magnetometer passes fitness tests and is ready to take data
The magnetometer instrument on the JUpiter ICy moons Explorer (JUICE) spacecraft has been rigorously tested and is ready to fulfil its mission. The magnetometer instrument (J-MAG), led by Imperial College London researchers, consists of three sensors, all of which were shown to be operating well. The deployment also marks the first time a quantum interference sensor - a precise but delicate technology - has been used beyond Earth orbit.

New material paves the way for more efficient electronics
Researchers from the University of Twente proved that germanene, a two-dimensional material made of germanium atoms, behaves as a topological insulator. It is the first 2D topological insulator that consists of a single element. It also has the unique ability to switch between 'on' and 'off' states, comparable to transistors.
