Hubble Camera Lost "For Good" 190

Several readers wrote in to tell us, following up on the recent story of the shutting down of Hubble's main camera, that program engineers are now saying that the camera is probably gone for good. The trouble resulted from a short circuit on Saturday in Hubble's most popular instrument, the Advanced Camera for Surveys. NASA engineers reported Monday that most of the camera's capabilities, including the ability to take the sort of deep cosmic postcards that have inspired the public, had probably been lost. We'll be pining for more of those amazing images until the James Webb launches in 2013.
Update: 01/30 23:28 GMT by KD : Reader Involved astronomer wrote in with an addendum / clarification to this story: "I'm a grant-funded astronomer at the Space Telescope Science Institute (www.stsci.edu) in Baltimore. I am very concerned that the article conveys the wrong idea about HST. While HST's science capacity is diminished with the loss of ACS, HST lives on and will continue to produce world-class science, even before its servicing mission in Sept. 2008, which will upgrade the instrument suite with the most sophisticated imagers in history." Read on for the rest of his note.

Transistor Made From Bose-Einstein Condensate 80

holy_calamity writes "US researchers have made a transistor from a Bose-Einstein condensate. They claim it to be the first step towards 'atomic circuits' that run with atoms instead of electrons. 'A small number of atoms can be used to control the flow of a large number of atoms, in much the same way that an FET uses a gate voltage to control a large electric current,' says lead research Alex Zozulya. The abstract of their paper is freely available."
