Some Proteins Change Their Folds to Perform Different Jobs
Unusual proteins that can quickly fold into different shapes provide cells with a novel regulatory mechanism.
The Shape-Shifting Squeeze Coolers
Push or crush a new class of materials, and they’ll undergo record-breaking temperature changes.
The Universal Law That Aims Time’s Arrow
A new look at a ubiquitous phenomenon has uncovered unexpected fractal behavior that could give us clues about the early universe and the arrow of time.
Swarming Bacteria Create an ‘Impossible’ Superfluid
Researchers explore a loophole that extracts useful energy from a fluid’s seemingly random motion. The secret? Sugar and asymmetry.
Quantum Correlations Reverse Thermodynamic Arrow of Time
A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.
First Support for a Physics Theory of Life
Take chemistry, add energy, get life. The first tests of Jeremy England’s provocative origin-of-life hypothesis are in, and they appear to show how order can arise from nothing.
The Quantum Thermodynamics Revolution
As physicists extend the 19th-century laws of thermodynamics to the quantum realm, they’re rewriting the relationships among energy, entropy and information.
A Debate Over the Physics of Time
According to our best theories of physics, the universe is a fixed block where time only appears to pass.
The Thermodynamic Theory of Ecology
Nature’s large-scale patterns emerge from incomplete surveys that borrow ideas from information theory.
