Investigating systems consisting of self-propelled particles, also known as active particles, is currently a rapidly growing area of research. In theoretical models for active particles, it is commonly assumed that the particles’ swimming speed remains constant. However, in many experimental scenarios, such as particles propelled by ultrasound for medical applications, the propulsion speed depends on

In the realm of wave mechanics, the interaction between light and matter has long been a topic of interest. It is well-known that when light encounters a medium, its speed appears to slow down. However, a recent study conducted by researchers from the University of Eastern Finland and Tampere University has shed new light on

When we think of illuminating something with a brighter light source, we expect the resulting image to be brighter as well. This rule holds true for ultra-short pulses of laser light, including X-rays. However, recent research has revealed a counterintuitive effect – at very high X-ray intensities, diffraction images “darken” instead of becoming brighter. This

From the moment Antonie van Leeuwenhoek uncovered the microscopic world of bacteria in the seventeenth century, scientists have been tirelessly striving to delve deeper into the realm of the infinitesimally small. The diffraction limit, a physical constraint that arises from the wave nature of light, sets a boundary on how closely we can scrutinize an

We find ourselves in an era of immense data, where information flows incessantly.
