Researchers offer theoretical description of topological water wave structures

Topological wave structures are wave patterns that exhibit specific topological properties, or in other words, properties that remain unvaried under smooth deformations of a physical system. These structures, such as vortices ...

A magnetohydrodynamic drive could lead to fuel stations on Mars

Within the next 15 years, NASA, China, and SpaceX plan to send the first crewed missions to Mars. In all three cases, these missions are meant to culminate in the creation of surface habitats that will allow for many returns ...

How does a 'reverse sprinkler' work? Researchers solve decades-old physics puzzle

For decades scientists have been trying to solve Feynman's Sprinkler Problem: How does a sprinkler running in reverse—in which the water flows into the device rather than out of it—work? Through a series of experiments, a ...

Using dragonfly wings to study the relationship between corrugated wing structure and vortex motions

Scientists from Hiroshima University undertook a study of dragonfly wings in order to better understand the relationship between a corrugated wing structure and vortex motions. They discovered that corrugated wings exhibit ...

Cellular scaffolding rewired to make microscopic railways

Princeton researchers have learned to harness the gossamer scaffolding that maintains the structure of living cells and used it to develop a nanotechnology platform. The technique eventually could lead to advances in soft ...

Rocking our world: Understanding human-induced earthquakes

It is common knowledge that humans have a big effect on the world and their natural environment. However, what may be less well-known is that humans can also induce earthquakes. Industrial activities such as geothermal energy ...

Feeding mode of ancient vertebrate tested for first time

A feeding method of the extinct jawless heterostracans, among the oldest of vertebrates, has been examined and dismissed by scientists at the University of Bristol, using fresh techniques.

Shape of water jet found to influence sound of impact on still water

A trio of mechanical engineers at Seoul National University has found that the shape of a water jet dropped into a glass of water is the determining factor in the noise that results. In their paper published in the journal ...

Stripes in a flowing liquid crystal suggest a route to 'chiral' fluids

Hold your hands out in front of you, and no matter how you rotate them, it's impossible to superimpose one over the other. Our hands are a perfect example of chirality—a geometric configuration by which an object cannot be ...
