Twists between layers of crystalline sheets block heat going through layers
Random twists between layers of crystalline sheets block heat going through the layers, but still maintain good heat flow along the sheets. Researchers measured an astonishing factor of 900 in the difference in heat flow. [Research supported by U.S. National Science Foundation grants DMR ...This is an NSF Multimedia Gallery item.

Researchers are developing a tool that may someday help dentists identify high acidity.
Dental cavities and gum disease disproportionately impact low-income and rural communities. The major culprit is tooth decay, caused by a buildup of acid and plaque. Researchers are developing a tool that may someday help dentists identify high acidity. It is a hand-held device that can assess the ...This is an NSF Multimedia Gallery item.

Dental CT scans of lower molar of a rodent fossil
Dental CT scans show that mammal teeth became less diverse during the early Oligocene extinction events. This 3D tooth shape is of the lower molar of a rodent (Shazurus minutus) fossil in the anomaluroid family.

By the end of this century, Spring pollen emissions could begin 40 days earlier.
By the end of this century, Spring pollen emissions could begin 40 days earlier, making the allergy season even longer and more intense. People who have allergies could see the season last an additional 19 days, before high pollen counts subside. Scientists developed a model that examines 15 of the ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)
