Researchers uncover novel self-assembly of Alzheimer’s amyloid fibrils

Researchers at Emory University and Argonne National Laboratory have discovered a new method to manipulate the self-assembly and formation of amyloid fibrils, a major component of brain plaques associated with Alzheimer’s disease, thereby opening new avenues for examination of their formation and for the construction of robust nanotubes that have potential applications in research, industry and medicine.

Key to baby-soft skin could be cheesy

For nine months before birth, infants soak in a watery, urine-filled environment. Just hours after birth, however, they have near-perfect skin. How is it that nature enables infants to develop ideal skin in such seemingly unsuitable surroundings? A new study by researchers at the Skin Sciences Institute of Cincinnati Children?s Hospital Medical Center shows that the answer may be vernix — the white, cheesy substance that coats infants for weeks before they are born, then is wiped off and discarded immediately after birth. If they?re right, the healthcare implications for newborns and adults could be remarkable.
