When vibrations increase on cooling: Anti-freezing observed

An international team has observed an amazing phenomenon in a nickel oxide material during cooling: Instead of freezing, certain fluctuations actually increase as the temperature drops. Nickel oxide is a model system that ...

How do electrons behave in quantum critical ferromagnets?

In a classical second-order phase transition, condensed matter systems acquire long-range order upon cooling below the transition temperature, and the properties near the transition are driven by thermal fluctuations. These ...

Compressive fluctuations heat ions in space plasma

New simulations carried out in part on the ATERUI II supercomputer in Japan have found that the reason ions exist at higher temperatures than electrons in space plasma is because they are better able to absorb energy from ...

The deep sea is slowly warming

New research reveals temperatures in the deep sea fluctuate more than scientists previously thought and a warming trend is now detectable at the bottom of the ocean.

Forests have higher thermal buffer ability than non-forests

The contrasting structure and energy partitioning of different vegetation types moderate canopy surface temperature, and thus vegetation types may differ in their buffer ability toward temperature fluctuations. To better ...
