Particularly, they more deeply probed into the Walker breakdown phenomenon, on

People’s teeth-chattering experiences in the dentist’s chair could be improved by fresh insights into how tiny, powerful bubbles are formed by ultra-fast vibrations, a study suggests. The physics of how so-called nanobubbles are generated could have a range of clinical and industrial applications, including in dental hygiene devices used to remove plaque, experts say. The

Scientists from the

Liquid structures – liquid droplets that maintain a specific shape – are useful for a variety of applications, from food processing to cosmetics, medicine, and even petroleum extraction, but researchers have yet to tap into these exciting new materials’ full potential because not much is known about how they form. Now, a research team led

Baby mice might be small, but they’re tough, too. For their first seven days of life, they have the special ability to regenerate damaged heart tissue. Humans, on the other hand, aren’t so lucky: any heart injuries we suffer could lead to permanent damage. But what if we could learn to repair our hearts, just

These are large facilities in which electrons are accelerated to almost the speed of light, and then emit light pulses

The next generation of supercomputers – including quantum computers – is at a crucial point: Tomorrow’s high-performance computers are at their physical limit in terms of miniaturization of their components; at the same time, they must be more energy-efficient and increase in performance. In this context, the international research network SuperGate coordinated by the University
