Researchers have developed a theory suggesting the existence of quantum viscosity in superfluids, potentially bridging classical and quantum hydrodynamics. This novel approach, which involves analyzing the fall of a sphere in a superfluid, seeks to validate the Reynolds similitude in a quantum context, challenging long-held beliefs in fluid dynamics. Credit: SciTechDaily.comA theoretical framework aimed at measuring Reynolds similitude in superfluids could potentially prove the presence of quantum viscosity.Every liquid…

Researchers at Osaka Metropolitan University have innovatively reprogrammed canine stem cells from urine to create induced pluripotent stem cells (iPSCs) without feeder cells. This breakthrough in non-invasive, pain-free stem cell generation paves the way for new advancements in veterinary regenerative medicine and genetic disease research, offering hope for treating previously incurable diseases in dogs.

Astronomers discovered a high-energy cosmic particle named “Amaterasu,” with an unprecedented energy level of 244 EeV, using the Telescope Array experiment in Utah. This rare cosmic ray, comparable to the historic “Oh-My-God” particle, raises questions about its origin and composition.Unknown extremely energetic particle from space detected and named after Japanese myth.A high-energy particle falls from space to the Earth’s surface—it is not clear where it came from or even what it is, exactly. This may sound like…

Chemists have innovated a method to convert persistent PFAS into valuable fluorine-decorated N-heterocyclic carbenes (NHCs), potentially revolutionizing applications in several chemistry and materials science fields.Scientists have developed an innovative approach to incorporate harmful perfluoroalkenes into N-heterocyclic carbene ligands.Commonly known as “forever chemicals,” PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances) are notorious for their persistence in both the environment and our bodies. However, chemists…

A new technology 'piezoelectric vibration energy harvester' amplifies the electrical power generated by human walking motion by about 90 times in a way that could power small wearable devices, a report has showed.Energy harvesting is a technology that converts energy such as heat and light into electricity that can power small devices.A research team led by Associate Professor Takeshi Yoshimura from the Osaka Metropolitan University has developed a harvester that is only approximately 2 cm in diameter and has a U-shaped…
