New label-free 3D imaging technology offers breakthrough in diagnosing and treating lysosomal storage diseases

Researchers have developed a groundbreaking method to observe lysosomes in live suspended cells—quantitatively, in 3D, and without the use of chemical labels. The technology uses holographic tomography in flow cytometry configuration (HTFC) to identify morphological and spatial lysosomal changes in models of lysosomal storage diseases.

Potatoes may increase risk of type 2 diabetes—depending on their preparation

A new study found that consuming three servings of French fries weekly increased the risk of developing type 2 diabetes by 20%. In contrast, baked, boiled, or mashed potatoes were not significantly associated with T2D risk. Swapping any form of potato for whole grains may lower the risk of T2D, with a 4% reduction in risk estimated.
