Phys.org / How approaching sounds can warp your perception of time

Everyone's perception of time is unique. It is a subjective experience shaped by factors such as age, emotions, memory and environmental contexts. And it may also be influenced by background noise, as scientists have demonstrated ...

Phys.org / Medieval text family trees suggest 60% of works vanished over centuries

For every King Arthur or Roland, whose adventures readers can still enjoy today, another hero of ancient literature may have been lost forever. Before the printing press, texts were copied manually. This process introduced ...

Phys.org / Metallic rutile oxides break the rules of cooling

Physicists have long puzzled over a strange contradiction inside a family of minerals called rutile oxides. These materials all share the same crystal structure—but while some of them, like titanium dioxide, are firmly insulating, ...

Phys.org / Measuring iron in motion at Earth-core conditions

It was a journey to the center of the Earth, if only for the briefest of moments. But rather than tunneling thousands of miles from Earth's surface, researchers from Lawrence Livermore National Laboratory (LLNL) and several ...

Phys.org / JWST finds the most distant barred galaxy candidate in the early universe

Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its ...

Phys.org / New ultrathin lens focuses light into an optical needle

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence ...

Phys.org / Tiny carbon rings enable a new form of quantum control

Quantum states can be precisely controlled with the help of tiny carbon rings measuring only a few nanometers in size. This is made possible by a class of rarely used electromagnetic dipoles called toroidal moments. Using ...

Phys.org / 'Cosmic wallflowers' may hold the key to the origin of globular clusters

Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, ...

Phys.org / Researchers develop AI tool that finds the equations behind complex systems

Clarkson University researchers have developed an artificial intelligence tool that can uncover the mathematical equations governing complex and chaotic systems directly from data. The technology, called KANDy—short for Kolmogorov-Arnold ...

Phys.org / Simple cell migration mechanism may explain how hair follicles organize before birth

In mammals, hair follicles emerge during embryonic development, forming geometric patterns that vary from one species to another. But how is the position of each hair determined? A team from the University of Geneva (UNIGE) ...
