This study presents a new method for evaluating cosmetic treatments by measuring the resistance of hair to mechanical wear, revealing differences related to hair ethnicity and treatment type.

New resin B makes artificial hair fibers hold curls longer than traditional resin A.

This study found that single-crystal magnesium samples smaller than 100 nm exhibited increased plastic deformation due to greater activation of nonbasal planes as local flow stresses approached 2 GPa.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

The document concludes that human astrocytes aid stroke recovery, research confidence affects student career aspirations, collagen affects cancer spread, a microRNA suppresses brain cancer growth, calmodulin regulates water channels, and small magnesium pieces deform differently.
