Shag writes "Type Ia supernovae are used as cosmological 'standard candles' to measure distance because of their strong similarity to one another. This has made possible, for example, the research into universal expansion that led to the Nobel-winning discovery of 'dark energy.' For years, astrophysicists believed white dwarves exploded when they accreted enough mass from companion stars to reach a limit of 1.38 times the mass of our Sun. A decade ago, the 'Champagne supernova' (SN 2003fg) was so bright astrophysicists concluded the limit had been exceeded by two white dwarves colliding. Now a new paper (PDF) from the Nearby Supernova Factory collaboration suggests that type Ia supernovae occur at a wider range of stellar masses. Fortunately, there appears to be a calculable correlation between mass and light-curve width, so they can still fill the 'standard candle' role, and research based on them is probably still valid. (I took data for the paper, but am not an author.)"

itwbennett writes "Oregon is holding back $25.6 million in payments from Oracle (out of some $69.5 million Oracle claims it is owed) over work the vendor did on the state's troubled health care exchange website. The site was supposed to go live on Oct. 1 but its launch has been marred by a slew of bugs and it is not yet fully functional. This week, Cover Oregon said it had reached an agreement with Oracle laying out 'an orderly transition of technology development services, and protects current and future Cover Oregon enrollees,' according to a statement. Oregon officials reached the deal with Oracle after the company reportedly threatened to pull all of its workers off the project and essentially walk away."
