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.
The study, to be presented May 6 at the annual meeting of the Pediatric Academic Societies in Seattle, shows that newborn skin with vernix left intact “is more hydrated, less scaly, and undergoes a more rapid decrease in pH than with vernix removed,” says Marty Visscher, PhD, executive director of the Skin Sciences Institute and the study’s main author. “These beneficial effects of vernix suggest that it should be left intact at birth.”

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
