Fundamental discoveries for future nanotools: Chemists distinguish multiple weak forces

The process of building a tiny cube has revealed some of the fundamental mysteries of how molecules bind together in natural environments. Researchers hope to apply this knowledge to future projects designing complex structures that can mimic life. When two molecules surrounded by water move towards each other, part of their initial attraction is sometimes … Read more Fundamental discoveries for future nanotools: Chemists distinguish multiple weak forces

Injection of magnetizable fluid could extend trauma patients’ survival time

Inspired by their use in mechanical systems, Massachusetts Institute of Technology researchers are testing a magnetically-actuated fluidic valve to use in trauma patients suffering from hemorrhage. Yonatan Tekleab and his colleagues will explain how the valve works at the American Physical Society’s Division of Fluid Dynamics 72nd Annual Meeting on Nov. 25 at the Washington … Read more Injection of magnetizable fluid could extend trauma patients’ survival time

Fossils reveal swimming patterns of long extinct cephalopod

Computational fluid dynamics can be used to study how extinct animals used to swim. Scientists studied 65 million-year-old cephalopod fossils to gain deeper understanding of modern-day cephalopod ecosystems. Three scientists affiliated with the University of Utah’s department of geology and geophysics will present research on the width, coil diameter and the overall structure of the prehistoric cephalopods … Read more Fossils reveal swimming patterns of long extinct cephalopod

Shaking head to get rid of water in ears could cause brain damage

Trapped water in the ear canal can cause infection and even damage, but it turns out that one of the most common methods people use to get rid of water in their ears can also cause complications. Researchers at Cornell University and Virginia Tech show shaking the head to free trapped water can cause brain … Read more Shaking head to get rid of water in ears could cause brain damage

Optimal archery feather design depends on environmental conditions

When it comes to archery, choosing the right feathers for an arrow is the key to winning. This necessity for precision makes it crucial to understand how environment and design effect arrows in flight. Scientists from the Laboratoire d’Hydrodynamique at the Ecole Polytehcnique will explain the physics behind optimal arrow design at the 72nd Annual … Read more Optimal archery feather design depends on environmental conditions
