Determining the shape of cells

Cells are constantly performing small tasks such as repairing wounds. They exert force by changing shape. But how do cells translate their shape into exerting a force in a specific direction? Experimental and theoretical ...

Physicist describes the shape of a wormhole

A RUDN physicist demonstrated how to describe the shape of any symmetrical wormhole—a black hole that theoretically can be a kind of a portal between any two points in space and time—based on its wave spectrum. The research ...

Scientists find holes in light by tying it in knots

A research collaboration including theoretical physicists from the University of Bristol and Birmingham has found a new way of evaluating how light flows through space—by tying knots in it.

Unusual sound waves discovered in quantum liquids

Ordinary sound waves—small oscillations of density—can propagate through all fluids, causing the molecules in the fluid to compress at regular intervals. Now physicists have theoretically shown that in one-dimensional ...
