Experiment resolves mystery about wind flows on Jupiter
Using a spinning table and a massive garbage can, geophysicist leads team in simulating the planet’s atmosphere
One mystery has been whether the jets exist only in the planet’s upper atmosphere – much like Earth’s own jet streams – or whether they plunge into Jupiter’s gaseous interior. If the latter is true, it could reveal clues about the planet’s interior structure and internal dynamics.
Now, UCLA geophysicist Jonathan Aurnou and collaborators in Marseille, France, have simulated Jupiter’s jets in the laboratory for the first time. Their work demonstrates that the winds likely extend thousands of miles below Jupiter’s visible atmosphere.

Graphene Roll-Ups Make Friction Disappear, Could Revolutionize Machine Engineering
Chalk another amazing ability up for the supermaterial graphene. It seems the atom-thick sheets of linked carbon atoms can virtually eliminate friction.
The simulation above depicts the graphene-lubricant discovery–blue graphene sheets roll up to encase gold nanodiamonds as a surface of black diamond-like carbon slides over. Once the graphene wraps into so-called nanoscrolls around the nanodiamonds, the sheets make friction disappear.
