Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital watches. The findings are a simple and inexpensive way to manipulate the molecular properties of liquid crystals with light exposure.

Geologists determined the original orientation of many of the Mars bedrock samples collected by the Perseverance rover. The findings can give scientists clues to the conditions in which the rocks originally formed.

Scientists have pioneered a new methodology of fabricating carbon-based quantum materials at the atomic scale by integrating scanning probe microscopy techniques and deep neural networks. This breakthrough highlights the potential of implementing artificial intelligence at the sub-angstrom scale for enhanced control over atomic manufacturing, benefiting both fundamental research and future applications.

Astronomers can use supercomputers to simulate the formation of galaxies from the Big Bang 13.8 billion years ago to the present day. But there are a number of sources of error. An international research team has spent a hundred million computer hours over eight years trying to correct these.

A study shows that similarly charged particles can sometimes attract, rather than repel. The team found that like-charged particles suspended in liquids can attract one another at long-range, depending on the solvent and the sign of the charge. The study has immediate implications for processes that involve interactions in solution across various length-scales, including self-assembly, crystallization, and phase separation.

Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to disperse.

Astrobiologists have devised a novel way to determine ocean temperatures of distant worlds based on the thickness of their ice shells, effectively conducting oceanography from space.

Using archival data from the Gemini North telescope, a team of astronomers has measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been predicted, though never observed. This massive pair gives clues as to why such an event seems so unlikely in the Universe.

An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth -- but how would this technology fare on the Moon, and what would it tell us about the deep layers of our nearest neighbor in space?

Researchers have found water vapor in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never been able to map how water is distributed in a stable, cool disc -- the type of disc that offers the most favorable conditions for planets to form around stars.

Researchers have recovered gold from electronic waste. Their highly sustainable new method is based on a protein fibril sponge, which the scientists derive from whey, a food industry byproduct.

Playing a different sound track is, physically speaking, only a minute change of the vibration spectrum, yet its impact on a dance floor is dramatic. People long for this tiny trigger, and as a salsa changes to a tango completely different collective patterns emerge. For such a tiny stimulus to have an effect, the crowd needs to know more than just one dance. Electrons in metals tend to show only one behavior at zero temperature, when all kinetic energy is quenched.

An international team of astronomers obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars.

Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.

Scientists working with data from NASA's James Webb Space Telescope (JWST) have obtained the first full spectra of some of the earliest starlight in the universe. The images provide the clearest picture yet of very low-mass, newborn galaxies, created less than a billion years after the Big Bang, and suggest the tiny galaxies are central to the cosmic origin story.

Chemists fill a major gap in origin-of-life theories.

Researchers think they have a foundational tool for the thorny problem of how to measure and image the behavior of hydride superconductors at high pressure. They report creatively integrating quantum sensors into a diamond anvil cell, enabling direct readouts of the pressurized material's electrical and magnetic properties.
