Recently Discovered Pulsars and Unidentified Egret Sources
We present a correlative study between all unidentified EGRET sources at low Galactic latitudes and the newly discovered pulsars in the released portion of the Parkes multibeam radio survey. We note 14 positional coincidences: eight of these are “Vela-like” pulsars, with relatively small periods, small characteristic ages, and high spin-down luminosities. Three of these coincidences have been i...
متن کاملAbundances of Recently Discovered Planetary Nebulae
In this work we report spectrophotometric observations of a planetary nebula sample towards the galac-tic bulge. A total of 45 PNe was observed and their physical parameters (electron density and temperature) were derived. Ionic abundances were calculated using a three-level atom model and abundances were derived through ionisation correction factors. Results show low abundance objects at high ...
متن کاملCaenorhabditis elegans embryonic axial patterning requires two recently discovered posterior-group Hox genes.
Hox genes encode highly conserved transcription factors that control regional identities of cells and tissues along the developing anterior-posterior axis, probably in all bilaterian metazoans. However, in invertebrate embryos other than Drosophila, Hox gene functions remain largely unknown except by inference from sequence similarities and expression patterns. Recent genomic sequencing has sho...
متن کاملTWO HIGHLY POLARIZED QSOs DISCOVERED BY 2MASS
We present optical observations of two remarkable new AGN discovered by the Two-Micron All Sky Survey. Both are classified as QSOs based on their optical spectra, near-IR colors, and near-IR and [O III]λ5007 luminosities, but their optical polarizations are among the highest seen for non-blazar AGN; approaching 15% for 2MASSI J151653.2+190048. The polarized light spectrum for each object exhibi...
متن کاملBiological Activity of Recently Discovered Halogenated Marine Natural Products
This review presents the biological activity-antibacterial, antifungal, anti-parasitic, antiviral, antitumor, antiinflammatory, antioxidant, and enzymatic activity-of halogenated marine natural products discovered in the past five years. Newly discovered examples that do not report biological activity are not included.
