Discovery of 12-sided silica cages

Scientists report the discovery of 10-nanometer, individual, self-assembled dodecahedral structures -- 12-sided silica cages that could have applications in mesoscale material assembly, as well as medical diagnosis and therapeutics.

How physics explains the evolution of social organization

A scientist at Duke University says the natural evolution of social organizations into larger and more complex communities that exhibit distinct hierarchies can be predicted from the same law of physics that gives rise to tree branches and river deltas.

Better model of water under extreme conditions could aid understanding of Earth's mantle

A team of scientists ran quantum simulations to develop a new model of the behavior of water at extremely high temperatures and pressures. The computational measurements should help scientists understand water's role in the makeup of the mantle and potentially in other planets.

Gas flow through tiny atonically flat walls: Atomic-scale ping-pong

New experiments have shed more light on the gas flow through tiny, angstrom-sized channels with atomically flat walls.

Chameleon-inspired nanolaser changes colors

Chameleons change color by controlling the spacing among nanocrystals on their skin. The nanolaser changes color similarly -- by controlling the spacing among metal nanoparticles.

Researchers find last of universe's missing ordinary matter

Researchers at the University of Colorado Boulder have helped to find the last reservoir of ordinary matter hiding in the universe.

Cooler computing through statistical physics?

In the space inside a computer chip, where electricity becomes information, there's a scientific frontier. The same frontier can be found inside a cell, where information instead takes the form of chemical concentrations.

Quantum step forward in protecting communications from hackers

Researchers have shown that a new quantum-based procedure for distributing secure information along communication lines could be successful in preventing serious security breaches.

Interaction of paired and lined-up electrons can be manipulated in semiconductors

The way that electrons paired as composite particles or arranged in lines interact with each other within a semiconductor provides new design opportunities for electronics, according to recent findings.

Cooler computing through statistical physics?

Recent breakthroughs in nonequilibrium statistical physics have revealed opportunities to advance the 'thermodynamics of computation,' a field that could have far-reaching consequences for how we understand, and engineer, our computers.
