Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. Under different stresses and pressure gradients, other non-Newtonian fluids exhibit patterns of behavior that are much more complex.

In a recent paper in Nature Physics, an international research collaboration used world-class instrumentation at the Facility for Rare Isotope Beams (FRIB) to study the exotic nuclide, or rare isotope, chromium-62.

Researchers have developed a new ultrafast laser platform that generates ultra-broadband ultraviolet (UV) frequency combs with an unprecedented one million comb lines, providing exceptional spectral resolution. The new approach, which also produces extremely accurate and stable frequencies, could enhance high-resolution atomic and molecular spectroscopy.

Spectroscopic study on a kagome magnet thin film uncovers the local-moment nature of the magnetism in the presence of topological flat bands, as well as a strong spin-and orbital-selective electronic correlation effect.

Claudio Pellegrini, a professor of thermal and fluid sciences at the Federal University of São João del-Rei in Brazil, has calculated the optimal shape for a beer glass to keep the beer cold for as long as possible. He has written a paper describing his analysis of beer glass shapes and posted it on the arXiv preprint server.

Enough landmines are buried underground worldwide to circle Earth twice at the equator, but the identification and removal of these explosives is costly and time-consuming.

Sometimes a rotating molecule can transition to a new state only if an electron carries away some of the molecule’s angular momentum.

A study in the journal Plant Biology by researchers from Macquarie University and international collaborators has shown for the first time that plants reuse resources from wilting flowers to support future reproduction.

Lead author Honorary Professor Graham Pyke from Macquarie University says the findings help explain a common but poorly understood plant process.

“Our research delivers the first direct demonstration that plants can salvage resources from wilting flowers and reuse these resources to promote future reproduction,” Professor Pyke says.
