Mini-planet systems get stranger - BBC Mini planetary systems may orbit cosmic objects that are 100 times smaller than our Sun, research suggests. Discs of gas and dust, the ingredients needed to create such systems, have been seen circling these relatively small objects, dubbed "planemos". Located about 450 light-years away in a star-forming region, four of the objects are just a few million years old, making them cosmic "newborns". They have masses between five and 15 times that of Jupiter. But unlike Jupiter, these objects are floating through space without an accompanying star. |

Scientists get inside look at viruses - MSNBC Left: A new 3-D image shows the human immunodeficiency virus, or HIV, and the protein spikes on its surface that match up with host cells. Scientists at Florida State University recently produced a new 3-D image of HIV and the protein spikes on its surface that match up with host cells. The pictures may help researchers better understand how the virus fuses with a host T-cell and inspire new ways to design vaccines. Until now, the design details of the spikes and their distribution pattern on the surface of the virus membrane have been poorly understood, which has limited our understanding of how the virus infection actually occurs, and frustrated efforts to create vaccines." |
