3-D micro X-ray images help answer questions about fried foods' internal structure

Researchers used X-ray micro-computed tomography to study the microstructure of fried potato disks and observed how oil content and pathway networks change with frying time. The findings can be applied to other fried foods, revealing a correlation between pore size and oil uptake.

Let it go: Reaction to stress more important than its frequency

A study by Penn State and Columbia University found that individuals who experience more negative emotions and perceive stressful events as more stressful have lower heart rate variability, a risk factor for cardiovascular disease. This suggests that reaction to stress is more important than its frequency in determining health risks.
