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 ...

Western wildfires calm down in cool weather, but losses grow

Cooler weather on Tuesday helped calm two gigantic wildfires in the U.S. West, but a tally of property losses mounted as authorities got better access to a tiny California community savaged by flames last weekend and to a ...

When a single tree makes a difference

A single tree along a city street or in a backyard can provide measurable cooling benefits, according to a new study from American University. The research shows that "distributed" trees, those that are stand-alone and scattered ...

Optical tweezer technology tweaked to overcome dangers of heat

Three years ago, Arthur Ashkin won the Nobel Prize for inventing optical tweezers, which use light in the form of a high-powered laser beam to capture and manipulate particles. Despite being created decades ago, optical tweezers ...

Carbonate standards ensure better paleothermometers

The climate of ancient Earth left telltale signs in the geochemical record. On the basis of chemical properties of carbonate minerals, scientists can calculate a site's temperature hundreds of millions of years ago. Such ...
