Biophysicists Uncover Powerful Symmetries in Living Tissue
After identifying interlocking symmetries in mammalian cells, scientists can describe some tissues as liquid crystals — an observation that lays the groundwork for a fluid-dynamic theory of how tissues move.
Can Math and Physics Save an Arrhythmic Heart?
Abnormal waves of electrical activity can cause a heart’s muscle cells to beat out of sync. In this episode, Flavio Fenton, an expert in cardiac dynamics, talks with Steve Strogatz about ways to treat heart arrhythmias without resorting to painful defibrillators.
Starfish Whisperer Develops a Physical Language of Life
Nikta Fakhri is adapting and extending concepts from physics to describe how tiny biological components give rise to living organisms.
Record-Breaking Robot Highlights How Animals Excel at Jumping
Robots can surpass the limitations on how high and far animals can jump, but their success only underscores nature’s ingenuity in making the most of what’s available.
Electric Fish Genomes Reveal How Evolution Repeats Itself
By studying how electric organs arose in different lineages of fish, scientists gain new insights into a long-standing question of evolutionary biology.
Geometric Analysis Reveals How Birds Mastered Flight
Partnerships between engineers and biologists have begun to reveal how birds evolved their superb maneuverability.
Embryo Cells Set Patterns for Growth by Pushing and Pulling
Patterns that guide the development of feathers and other features can be set by mechanical forces in the embryo, not just by gradients of chemicals.
Wheel Made of ‘Odd Matter’ Spontaneously Rolls Uphill
Physicists have solved a key problem of robotic locomotion by revising the usual rules of interaction between simple component parts.
Powerful ‘Machine Scientists’ Distill the Laws of Physics From Raw Data
Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.
