Little Bang Most Likely Triggered Solar System Formation

For several decades, scientists have thought that the Solar System formed as a result of a shock wave from an exploding star — a supernova — that triggered the collapse of a dense, dusty gas cloud that contracted to form the Sun and the planets. But detailed models of this formation process have only worked under the simplifying assumption that the temperatures during the violent events remained constant. Now, astrophysicists at the Carnegie Institution's Department of Terrestrial Magnetism (DTM) have shown for the first time that a supernova could indeed have triggered the Solar System's formation under the more likely conditions of rapid heating and cooling. The results, published in the October 20, 2008, issue of the Astrophysical Journal, have resolved this long-standing debate.

NIST Releases Report On WTC 7 Collapse

photonic writes "After three years of study, the National Institute of Standards and Technology (NIST) finally released its report on the collapse of World Trade Center building 7. The main conclusion is that the building came down due to fire, not due to debris damage or some conspiracy demolition team. The fire started pretty small after the collapse of WTC 1, but was left to burn several floors out completely. The important finding is that the collapse was triggered by thermal expansion of beams, which could detach asymmetrically loaded girders from the main columns. Some limited pancaking of floors then caused a lack of lateral support and buckling of a single column. This triggered the failure of the entire core of the building, which finally fell down as a single piece.

Payments Changes at eBay Go Well Beyond Tossing out Checks

(September 16, 2008) When eBay Inc. announced its all-electronic payments policy last month, the move triggered what an eBay executive calls a “mixed” response, at best, from the online marketplace’s sprawling seller community. But the policy changes go beyond banning checks and money orders on eBay. They include requirements that will force third-party payments vendors, as well as sellers with merchant accounts, to integrate their payment systems with eBay’s checkout process. And they have vaulted an 11-year-old processor in Orem, Utah, into prominence as the first provider other than eBay’s PayPal unit to provide integrated electronic processing.
