VLBI observations at 5 GHz have revealed that supernova 1979C, in the galaxy M100 in the Virgo cluster, has shell structure. The shell is approximately circular with the 50% contour deviating from a circle by an rms of no more than 8% of the radius. The brightness distribution along the ridge may vary. The position of the center of the shell is at R.A.=12 h 22 m 58. s 66758 and decl.=15 • 47 ′ ...

During plant epidermal development, many cell types are generated fromprotodermal cells, a process requiringcomplex co-ordinationof cell division, growth, endoreduplication and the acquisition of differentiated cellular morphologies. Herewe show that theArabidopsis phytocalpain DEFECTIVE KERNEL 1 (DEK1) promotes the differentiated epidermal state. Plants with reduced DEK1 activity produce cotyl...
