Famous 'sandpile model' shown to move like a traveling sand dune

The so-called Abelian sandpile model has been studied by scientists for more than 30 years to better understand a physical phenomenon called self-organized criticality, which appears in many real-life situations such as the ...

Team finds two theoretical physics models to be equivalent

Two Yale-NUS College undergraduates are part of a research team that concluded that two different mathematical models, which describe the same physical phenomenon, are essentially equivalent. The discovery could have implications ...

Wine 'legs' and minibot motors

As any wine enthusiast knows, the "legs" that run down a glass after a gentle swirl of vino can yield clues about alcohol content. Interestingly, the physical phenomenon that helps create these legs can be harnessed to propel ...

Governing mechanisms of waves in fluids

The first detection of gravitational waves, which took place a few weeks ago, has brought attention to a physical phenomenon that had long been theorized: waves carry information and can signal extraordinary (or extreme) ...

Nanoparticles helping to recover more oil

When petroleum companies abandon an oil well, more than half the reservoir's oil is usually left behind as too difficult to recover. Now, however, much of the residual oil can be recovered with the help of nanoparticles and ...

Physicists discover a new kind of friction in the nanoworld

Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material wear. Investigating ...

How graphene and friends could harness the Sun's energy

(Phys.org) —Combining wonder material graphene with other stunning one-atom thick materials could create the next generation of solar cells and optoelectronic devices, scientists have revealed.

Movement of pyrrole molecules defy 'classical' physics

(Phys.org) —New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of 'classical' physics that govern our everyday world.
