We present the first X-ray detection of the very young pulsar PSR J1357−6429 (characteristic age of 7.3 kyr) using data from the XMM-Newton and Chandra satellites. We found that the spectrum is well described by a power-law plus blackbody model, with photon index Γ = 1.4 and blackbody temperature kBT = 160 eV. For the estimated distance of 2.5 kpc, this corresponds to a 2–10 keV luminosity of ∼...

The ERD2 gene, which encodes the yeast HDEL (His-Asp-Glu-Leu) receptor, is essential for growth (Semenza, J. C., K. G. Hardwick, N. Dean, and H. R. B. Pelham. 1990. Cell. 61:1349-1357; Lewis, M. J., D. J. Sweet, and H. R. B. Pelham. 1990. Cell. 61:1359-1363). SED5, when present in multiple copies, enables cells to grow in the absence of Erd2p. Sequence analysis of SED5 reveals no significant ho...
