Asymmetric interactions between different species of molecules have previously been demonstrated to result in self-organized patterns and functions. If one species A is attracted to B, but in turn, B is repelled by A, run-and-chase dynamic emerges.

Optical frequency combs, as a time and frequency “ruler,” have important applications in precision ranging. Conventional dual-comb ranging schemes utilize the optical Vernier effect to achieve long-distance measurements, and they typically require asynchronously secondary sampling, either after changing the repetition rates or swapping dual-comb roles.

Using a small bench-top reactor, researchers at the University of British Columbia (UBC) have demonstrated that electrochemically loading a solid metal target with deuterium fuel can boost nuclear fusion rates.

Practical fusion power that can provide cheap, clean energy could be a step closer thanks to artificial intelligence. Scientists at Lawrence Livermore National Laboratory have developed a deep learning model that accurately predicted the results of a nuclear fusion experiment conducted in 2022. Accurate predictions can help speed up the design of new experiments and […]
The mysterious substance called dark matter is intrinsically invisible. It cannot be directly observed—rather, its presence is inferred by its gravitational influence on the universe, such as binding galaxy clusters together and moving stars around their galaxy faster than they should.

A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical potential) and the ohm (unit of electrical resistance). This is a significant breakthrough because until now, no single instrument could measure all three primary electrical […]
Imagine a whirlpool spinning in a river, or a tornado swirling through the sky. They don’t just spin on the spot: they travel forward while maintaining that spiraling motion inside them. These twisting motions, called vortices, are powerful and organized spirals. Now, imagine light that behaves the same way: a beam of light that spins […]
One of the world’s most popular sports, badminton is played by around 220 million people across the globe. As with other racket sports, a well-executed serve can establish a consequential advantage at the start of a rally.

Solitonic waves—waves that keep their shape and direction of motion for a long time—have intrigued physicists for almost two centuries. In real-world circumstances, these waves eventually die out due to energy loss. A team of UvA physicists have now discovered how a particular type of interaction can be used to create very stable solitons, even […]
Baryons, composite particles made up of three quarks bound together via the so-called strong force, make up the most visible matter and have thus been the focus of numerous physics studies. Studying the rare processes via which unstable baryons decay into other particles could potentially contribute to the discovery of new physics that is not […]
According to theoretical predictions, within a millionth of a second after the Big Bang, nucleons had not yet formed, and matter existed as a hot, dense “soup” composed of freely moving quarks and gluons. This state of matter is known as quark-gluon plasma (QGP). Finding definitive evidence for the existence of QGP is crucial for […]
A team of Johns Hopkins engineers has developed a new, more powerful method to observe molecular vibrations, an advance that could have far-reaching implications for early disease detection.

There are high hopes for quantum computers: they are supposed to perform specific calculations much faster than current supercomputers and, therefore, solve scientific and practical problems that are insurmountable for ordinary computers. The centerpiece of a quantum computer is the quantum bit, qubit for short, which can be realized in different ways—for instance, using the […]
Researchers at NPL have reported a novel high-speed charge sensing method for ballistic electrons, a potentially useful technique in the fields of electron quantum optics, quantum electrical metrology, flying qubit technology, and signal sensing.

A team of international researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Johns Hopkins University and Duke University has discovered that a century-old theory describing turbulence in fluids also applies to a very bubbly problem: how rising bubbles stir the water around them.
