Cholera infections caused by Vibrio cholerae bacteria can be life-threatening and the trigger is the cholera toxin produced by the bacteria. It binds to the surface of intestinal cells—more precisely, to certain "sugar ...
Pouring cream into coffee creates a show of eddies that rivals Jupiter's roiling storms. But one clank of the spoon collapses all that black and tan chaos into a smooth, uniform brown. It turns out there's a lot to that mixing. ...
A new theory has finally deciphered the physical mechanisms of fracture in soft materials. This discovery could soon lead to new, defect-free materials that are more resistant and durable as well as environmentally friendly. ...
The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research believed that liquids can only be transported in fixed direction in species with specific liquid communication ...
Most of us are familiar with the classic example of a liquid-gas moving contact line on a solid surface: a raindrop, sheared by the wind, creeps along a glass windscreen. The contact line's movements depend on the interplay ...
Disease-causing microbes have evolved sophisticated strategies for invading the body, flourishing in often hostile environments and evading immune defenses. In a new study, Professor Cheryl Nickerson, her Arizona State University ...
Essential oils, also known as ethereal oils, are volatile, aromatic compounds derived from plants. Found in only about 10% of the plant kingdom, these oils are present in secretory structures such as glands, ducts, cavities, ...
In 1883, Osborne Reynolds injected ink into water in a short, clear pipe to observe its movement. His experiments showed that as the input water velocity increased, the flow went from laminar (smooth and predictable) to turbulent ...
Researchers discovered that microscopic liquid droplets swim toward solvent conditions that favor their dissolution. This mechanism may underlie some transport processes within living cells, and could be exploited to develop ...
From the rain drops rolling down your window, to the fluid running through a COVID rapid test, we cannot go a day without observing the world of fluid dynamics. Naturally, how liquids traverse across, and through, surfaces ...
