Breaking Into Tears with Microrheology to Design Custom Eye Drops
In Physics of Fluids, Vega et al. researched human tears at the micron level to reveal new ways of customizing artificial tears to address individual symptoms of dry eye disease. The detailed insights they gained about the composition and behavior of tears could also apply to the study of ocular pathogens as well as other biological fluids. The authors collected healthy human tears and tested 10 different formulations of artificial tears and applied microrheology methods using dynamic light scattering.
The Science Behind Skipping Stones
In Physics of Fluids, an interdisciplinary team presents a study of the dynamics of buoyant spheres at the air-water interface. Their work reveals complex hydrodynamics involved in forming horizontal air cavities and the transition between floating and skipping. One of the team's key findings is that as the pulling force and speed of the spheres increase, their behavior becomes more irregular. They also discovered larger pulling angles result in different air-cavity lengths, larger skipping distances, and earlier water exit behavior.
Acoustics researchers decompose sound accurately into its three basic components
Researchers have been looking for ways to decompose sound into its basic ingredients for over 200 years. In the 1820s, French scientist Joseph Fourier proposed that any signal, including sounds, can be built using sufficiently many sine waves. These waves sound like whistles, each have their own frequency, level and start time, and are the basic building blocks of sound.

Scientists synthesize isotopic atropisomers based on carbon isotope discrimination
In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that are mirror images of each other; they are often distinguished as either 'right-handed' or 'left-handed' by their absolute configuration. Enantiomers exhibit similar physical and chemical properties, except when interacting with polarized light and reacting with other chiral compounds, respectively.
