Penn Geophysicist Teams With Mathematicians to Describe How River Rocks Round | Penn Today
For centuries, geologists have recognized that the rocks that line riverbeds tend to be smaller and rounder further downstream. But these experts have not agreed on the reason these patterns exist. Abrasion causes rocks to grind down and become rounder as they are transported down the river. Does this grinding reduce the size of rocks significantly, or is it that smaller rocks are simply more easi

First-ever high-resolution images of a molecule as it breaks and reforms chemical bonds
First-ever high-resolution images of a molecule as it breaks and reforms chemical bonds by Lawrence Berkeley National Laboratory Almost as clearly as a textbook diagram, this image made by a noncontact atomic force microscope reveals the positions of individual atoms and bonds, in a molecule having 26 carbon atoms and 14 hydrogen atoms structured as three connected benzene rings.

Watch what happens when you wring out a washcloth in space

ISS Commander Chris Hadfield was recently asked by high school students Kendra Lemke and Meredith Faulkner to demonstrate what happens when you wring out a waterlogged washcloth in space. Hadfield was happy to oblige, and while the entire process is fun to watch (someone add squirting drinking water into a mechanically compressed washcloth while a microphone hovers in front

Quantum gas temperature drops below absolute zero (Wired UK)
Physicists have created a quantum gas capable of reaching temperatures below absolute zero and paving the way for future quantum inventions. The chilly substance was composed of potassium atoms which were held in a lattice arrangement using a combination of lasers and magnetic fields. According to a report in the Nature journal, by tweaking the magnetic fields the research team were able to force
