New Computer Model Predicts How Fracturing Metallic Glass Releases Energy at the Atomic Level

American Institute of Physics (AIP)

Metallic glasses are an exciting research target for tantalizing applications; however, the difficulties associated with predicting how much energy these materials release when they fracture is slowing down development of metallic glass-based products. Recently, researchers developed a way of simulating to the atomic level how metallic glasses behave as they fracture. This modeling technique could improve computer-aided materials design and help researchers determine the properties of metallic glasses. The duo reports their findings in the Journal of Applied Physics.

Study: Air Pollution Negatively Associated with U.S. National Park Visitation

Iowa State University

Poor air quality may influence how many visitors travel to U.S. national parks, according to a new study. The researchers matched air pollution data to monthly park visitation statistics at 33 of the most heavily visited national parks and found that visitation responds most to ozone during months with poor air quality.

Study First to Confirm Where Baby White Sharks ‘Hang Out’ in the North Atlantic

Florida Atlantic University

A team of scientists is the first to confirm the movement patterns and seasonal migrations of baby white sharks in the north Atlantic Ocean. They put the New York Bight shark nursery theory to test by deploying satellite and acoustic tags on 10 baby white sharks (less than 1 year old) off Long Island’s coast. Results provide novel insights into the distribution of this vulnerable early stage of life that complements recent work on larger white sharks.

The Relationship Between Charge Density Waves and Superconductivity? It’s Complicated.

Ames Laboratory

For a long time, physicists have tried to understand the relationship between a periodic pattern of conduction electrons called a charge density wave (CDW), and another quantum order, superconductivity, or zero electrical resistance, in the same material. Do they compete? Co-exist? Co-operate? Do they go their separate ways?
