How do pedestrians behave in a large crowd? How do they avoid collisions? How can their paths be modeled? A new approach developed by mathematicians from Würzburg and Nice provides answers to these questions.
Motorized molecules driven by light have been used to drill holes in the membranes of individual cells and show promise for either bringing therapeutic agents into the cells or directly inducing the cells to die.
A team of researchers at Caltech has developed a way to capture on film the superfast propulsive motion of Brownian objects, particularly those at the nanoscale. In their paper published on the open-access site Science Advances, ...
Quantum dots (QDs) have found so many applications in recent years, they can now be purchased with a variety of composite structures and configurations. Some are available suspended in a biologically friendly fluid, making ...
(Phys.org)—Complexity – defined as having emergent properties or traits that are not a function of, and are therefore difficult or inherently impossible to predict from, the discrete components comprising the system – is ...
(Phys.org)—An international team of researchers has developed a way to take advantage of chemotactic movement to carry drugs through the blood-brain barrier. In their paper published on the open access site Sciences Advances, ...
We may be capable of finding microbes in space—but if we did, could we tell what they were, and that they were alive?
New York | Heidelberg, 12 July 2017 Leonardo Da Vinci had already noticed it. There is a very peculiar dynamics of granular matter, such as dry sand or grains of wheat. When these granular particles are left on a vibrating ...
In the world of research, diffusion is understood as a process in which tiny particles disperse uniformly throughout a gas or liquid. Although these media are made up of individual particles, diffusion is perceived as a continuous ...
No one had ever come so close to the ideal laser before: theoretically, laser light has only one single color (also frequency or wavelength). In reality, however, there is always a certain linewidth. With a linewidth of only ...
