'Bottom-heavy squirmers' adopt characteristic group behaviours

From starling aberrations to self-turbulent fluids, 'active systems' encompass a wide family of phenomena in which individual objects propel themselves forward, allowing them to display intriguing collective behaviors. On ...

Extraction of skin interstitial fluid using microneedle patches

Interstitial fluid is a major component of the liquid environment in the body and fills the spaces between the body's cells. In contrast, blood circulates only within the circulatory vessels of the body and is composed of ...

Stresses and flows in ultra-cold superfluids

Superfluids, which form only at temperatures close to absolute zero, have unique and in some ways bizarre mechanical properties. Yvan Buggy of the Institute of Photonics and Quantum Sciences at Heriot-Watt University in Edinburgh, ...

Bubble dynamics reveal how to empty bottles faster

Bottle emptying is a phenomenon most of us have observed while pouring a beverage. Researchers from the Indian Institute of Technology Roorkee discovered how to make bottles empty faster, which has wide-ranging implications ...

Tiny polymer springs give a boost to environmental cleanup

A study from Sujit Datta's lab, led by graduate student Christopher Browne, found that a promising class of cleaning solutions behave in ways that both confound traditional fluid models and explain their usefulness to remediation ...
