[ Watch the Video: Fire Ants Being Smashed by Petri Dish ] redOrbit Staff & Wire Reports - Your Universe Online Fire ants are capable of joining together to form a waterproof structure capable of bouncing back to its original shape when stretched or compressed, according to research presented Tuesday at the annual meeting of the American Physical Society's (APS) Division of Fluid Dynamics (DFD). Researchers from the Georgia Institute of Technology explain that these ants can...

Bacteria Swim With Help From High-angle Helix
2013-08-13 15:33:24

Brown University It’s counterintuitive but true: Some microorganisms that use flagella for locomotion are able to swim faster in gel-like fluids such as mucus. Research engineers at Brown University have figured out why. It's the angle of the coil that matters. Findings are reported in Physical Review Letters. A high-angle helix helps microorganisms like sperm and bacteria swim through mucus and other viscoelastic fluids, according to a new study by researchers from Brown University...

The new measurements, by UCLA physics professor Giovanni Zocchi and former UCLA physics graduate student Yong Wang, are approximately 100 times higher in resolution than previous mechanical measurements, a nanotechnology feat which reveals an isolated protein molecule, surprisingly, is neither a solid nor a liquid. "Proteins are the molecular machines of life, the molecules we are made of," Zocchi said. "We have found that sometimes they behave as a solid and sometimes as a liquid. "Solids...
