To move a heavy statue, try a little water

Prof. Roy Bar-Ziv, Alexandra Tayar and Eyal Karzbrun (l-r) created a lifelike wavefront of information

An array of artificial cells demonstrates the movement of information wavefronts

The sound of a violin arises from a type of friction known as "stick-slip"
What do the sounds of a creaky old hinge and a cello have in common? Both rely on the same kind of friction: two surfaces that alternately stick...

A new method for “writing” tiny channels in solid surfaces may lead to more natural information storage systems

Several molecules must work together for proper joint lubrication. In this illustration, the lubricin molecules anchor the long hyaluronan chains to the cartilage collagen network; these hyaluronan chains in turn attach the phospholipid molecules in either single layers (green) or double layers (blue)

Lab experiments reveal that lubricating our knees and hips is a “joint” effort

A chicken heart muscle cell under a fluorescent microscope; the filaments consist of repeated subunits (bright dotted lines). The schematic representation shows three neighboring filaments; the black lines are the boundaries of their subunits, such that the lower filament is aligned with the middle one, while the upper one is not
A new model shows that the filaments in heart muscle cells don't automatically keep the beat
