Patience and complexity are the hallmarks of fundamental scientific research. Work at the Department of Energy (DOE) Office of Science takes time.

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.
Discover how new research shows AMD and Intel processors remain vulnerable to speculative execution attacks.
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.
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.
