Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers made stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated.

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.

Researchers have discovered that nuclear spin influences biological processes, challenging long-held beliefs. They found that certain isotopes behave differently in chiral environments, affecting oxygen dynamics and transport. This breakthrough could advance biotechnology, quantum biology, and NMR technology, with potential applications in isotope separation and medical imaging.

Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists report that they can thus confirm the wave-like movement of nuclear material more precisely that ever before and that they have found no evidence of any deviation from the established force between atomic nuclei.

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere -- causing it to puff off the planet.

Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.
