Phys.org / Dark stars could help solve three pressing puzzles of the high-redshift universe
A recent study provides answers to three seemingly disparate yet pressing cosmic dawn puzzles. Specifically, the authors show how dark stars could help explain the unexpected discovery of "blue monster" galaxies, the numerous ...
Phys.org / Entanglement enhances the speed of quantum simulations, transforming long-standing obstacles into a powerful advantage
Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding quantum entanglement. This phenomenon, which has long been viewed as a significant obstacle in classical ...
Phys.org / Self-configuring optical devices automatically learn how to sort out light
Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different optical patterns at once is extremely complicated, and remains a major challenge in modern photonics.
Phys.org / Quantum phenomenon enables a nanoscale mirror that can be switched on and off
Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes, but also at the nanometer scale. Recently, physicists at the University of Amsterdam published ...
Phys.org / Simultaneous packing structures in superionic water may explain ice giant magnetic fields
Superionic water—the hot, black and strangely conductive form of ice that exists in the center of distant planets—was predicted in the 1980s and first recreated in a laboratory in 2018. With each closer look, it continues ...
Phys.org / Cells use Morse code-like rhythms to coordinate growth
Cells experience many different types of stress, such as starvation or stress caused by too much salt or too high a temperature. Insulin signals respond to such stress signals by sending the protein DAF-16 into the cell nucleus ...
Phys.org / Astrophysicists map how many ghost particles all the Milky Way's stars send towards Earth
They're called ghost particles for a reason. They're everywhere—trillions of them constantly stream through everything: our bodies, our planet, even the entire cosmos. These so-called neutrinos are elementary particles ...
Phys.org / Behind nature's blueprints: Physicists create 'theoretical rulebook' of self-assembly
Inspired by biological systems, materials scientists have long sought to harness self-assembly to build nanomaterials. The challenge: the process seemed random and notoriously difficult to predict.
Phys.org / Some dogs can learn new words by eavesdropping on their owners
"Honey, will you take Luna to the P-A-R-K?" Both parents and dog owners know that some words should not be spoken, but only spelled, to prevent small ears from eavesdropping on the conversation. At the age of 1.5 years, toddlers ...
Phys.org / The electrifying science behind Martian dust
Mars, often depicted as a barren red planet, is far from lifeless. With its thin atmosphere and dusty surface, it is an energetic and electrically charged environment where dust storms and dust devils continually reshape ...
Phys.org / Deep Sulawesi cave dig could reveal overlap between extinct humans and us
Could Homo sapiens and an archaic and now-extinct species of early human have lived alongside each other on the Indonesian island of Sulawesi more than 65,000 years ago?
Phys.org / How did these strange, ancient organisms turn into such remarkable fossils?
In Earth's fossil record, soft-bodied organisms like jellyfish rarely stand the test of time. What's more, it's hard for any animal to get preserved with exceptional detail in sandstones, which are made of large grains, are ...
