Mars may act as a giant planetary pump

(Phys.org) —The surface of Mars is full of activity, with dust storms, dust devils, and drifting dunes in constant motion. Scientists suspect that similarly rich activity may exist underneath the surface, even though it ...

What happened to Mars's water? It is still trapped there

Billions of years ago, the Red Planet was far more blue; according to evidence still found on the surface, abundant water flowed across Mars and forming pools, lakes, and deep oceans. The question, then, is where did all ...

Sand dunes can 'communicate' with each other

Even though they are inanimate objects, sand dunes can 'communicate' with each other. A team from the University of Cambridge has found that as they move, sand dunes interact with and repel their downstream neighbours.

Electromagnetic water cloak eliminates drag and wake

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while simultaneously helping it avoid detection.

Physicists create water tractor beam

Physicists at The Australian National University (ANU) have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.

First rainforests arose when plants solved plumbing problem

A team of scientists, including several from the Smithsonian Institution, discovered that leaves of flowering plants in the world's first rainforests had more veins per unit area than leaves ever had before. They suggest ...

MRI zooms in on microscopic flow (w/ Video)

(PhysOrg.com) -- MRI images of water flow through a constricted microfluidic channel with the XZ axis on the left and the YZ axis on the right. Note that fast moving components directly aligned with the constricted region ...

Hydrokinetic proposal for Mississippi river

(PhysOrg.com) -- Everyone is looking for alternative forms of energy, and one company proposes to generate electricity from the flow of the river Mississippi in the US, without using dams to control the water flow.
