Researchers Propose Solutions for Urine Sample Splash Dilemma

American Physical Society's Division of Fluid Dynamics

Urinating into a cup may be a medical necessity at times, but it's often uncomfortable, embarrassing and messy -- especially for women. But what if there were a way to comfortably provide a sample without the splashback? Researchers have created a set of experiments using an anatomically correct female urethra that produced a jet of water with a pressure and flow equivalent to a human bladder. During the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, they’ll describe the findings and potential implications.

Swarmlike Collective Behavior in Bicycling

American Physical Society's Division of Fluid Dynamics

Nature is full of examples of large-scale collective behavior; humans also exhibit this behavior, most notably in pelotons, the mass of riders in bicycle races. Using aerial video footage of bicycle races, researchers analyzed peloton motion to determine what causes changes in the group’s large-scale collective behavior and found that riders move through the peloton in a manner similar to circulation in a fluid. During the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, they will describe their work on collective behavior in pelotons.

Helping Marvel Superheroes to Breathe

American Physical Society's Division of Fluid Dynamics

Marvel comics superheroes Ant-Man and the Wasp possess the ability to temporarily shrink down to the size of insects, while retaining the mass and strength of their normal human bodies. But a new study suggests that, when bug-sized, Ant-Man and the Wasp would face serious challenges, including oxygen deprivation. Those challenges, along with their solution-microfluidic technologies, will be described at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.

Explaining a Fastball’s Unexpected Twist

American Physical Society's Division of Fluid Dynamics

An unexpected twist from fastball can make the difference in winning or losing the World Series. However, “some explanations regarding the different pitches are flat-out wrong,” said Barton Smith, a professor of mechanical and aerospace engineering at Utah State University who considers himself a big fan of the game. He and Nazmus Sakib are conducting experiments to explain how baseballs move. Sakib and Smith will present their findings at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.

Scientists Explain How Wombats Drop Cubed Poop

American Physical Society's Division of Fluid Dynamics

Wombats are central to a biological mystery in the animal kingdom: How do they produce cube-shaped poop? Patricia Yang at Georgia Tech set out to investigate. Yang studies the hydrodynamics of fluids, including blood, processed food and urine, in the bodies of animals. She was curious how the differences in wombats’ digestive processes and soft tissue structures might explain their oddly shaped scat. During the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, Yang will explain findings from dissecting the alimentary systems of wombats.

New resources support tribes in preparing for climate change

University of Washington

The University of Washington Climate Impacts Group and regional tribal partners have developed a collection of resources that may be useful to tribes at any stage in the process of evaluating their vulnerability to climate change. The project is a partnership among tribes, tribal associations, universities and the federal government.
