Transformation of spin information into large electrical signals using carbon nanotubes
Article Abstract:
The large magnetoresistance effects corresponding to large output signals in the devices where the non-magnetic channel is a multiwall carbon nanotube (CNT) spanning a 1.5 [micro]m gap between epitaxial electrodes of the highly spin polarized manganite [La.sub.0.7][Sr.sub.0.3]Mn[O.sub.3] (LSMO) are reported. The spintronic system combines a number of favorable properties that enable the long spin lifetime in nanotubes, high Fermi velocity in nanotubes, the high spin polarization in the manganite electrodes and the resistance of the interfacial barrier for spin injection.

A single type of progenitor cell maintains normal epidermis
Article Abstract:
Previous models of epidermal homeostasis theorized two different types of progenitor cells maintaining skin tissue. The experiments conducted in mouse tail epidermis show single type progenitor cell undergoing unlimited number of divisions to maintain normal epidermis.

The epidermis both drives and restricts plant shoot growth
Article Abstract:
The function of epidermis in growth of plants is examined. The non-autonomous signal generated from epidermis by brassinosteroid hormone promotes growth in internal tissues thus epidermis plays crucial role in overall growth of plants.
