Clade C es el subtipo más prevalente de HIV-1 en el mundo. La estructura cristalina del núcleo de clade C gp120 es descrito por Bjorkman y colegas, en conjunto con el complejo CD4 y el receptor CD4 - inducidos por anticuerpo. El trabajo revela que el anticuerpo hace contacto con ambos, gp120 y CD4.

Astronomers released the most complete three-dimensional map of the local Universe so far, covering almost the whole infrared sky, at the American Astronomical Society meeting in Boston on 25 May. The 2MASS Redshift Survey scanned the sky in the near-infrared spectrum to produce a two-dimensional map, and combined that with redshifts measured by the late John Huchra of Harvard University to give the third dimension. The map shows around 45,000 galaxies up to 290 million parsecs away, including previously unknown ones in the plane of the Milky Way, which had been obscured by dust in earlier images.
