Inside cells, certain functions are carried out by locally adjusting molecular composition. This condensation of material results in the formation of dense droplets that can dynamically rearrange. Because of this, interactions ...
In physics, the spontaneous de-mixing of two substances is known as phase separation. It is an important mechanism in nature to create structure and patterns and typically requires some form of attraction between the constituents. ...
Sitting in a restaurant, you reach for the ketchup bottle, eyeing the basket of fries in front of you. You give the bottle a shake, then a tap. For a moment, nothing happens—the ketchup clings stubbornly to the glass. Then, ...
Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, known as Cooper pairs.
Aromatic molecules are known for their stable electronic structures. These molecules typically adopt planar geometries with delocalized π-electrons and can form assemblies through π–π stacking interactions. In contrast, antiaromatic ...
Physicists in China have simulated the effect of "false vacuum decay": a phenomenon believed to play out constantly in the seemingly empty expanses of space, and which one theory even suggests could bring an abrupt end to ...
A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global ...
When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after replication. Instead, ...
The world is never really at rest. Even in a vacuum near ultracold temperatures where all classical motion should come to a halt, you'll find quantum fluctuations. In thin, two-dimensional materials, these include random ...
Plastic contamination in freshwater ecosystems continues to rise, resulting in micro- and nanoparticle accumulation in the aquatic environment. A new study by an aquatic ecology group at the University of Eastern Finland ...
