ACS Analyzes WTC Dust; Edward Teller Dies

:: The American Chemical Society is holding its annual meeting in NYC this week, and researchers still do not know if there are any long-term effects to be expected.

    When the World Trade Center collapsed, more than a million tonnes of pulverized cement, glass and insulation dust were thrown into the air. Fires continued to belch fumes until mid-December - and many rescue workers developed the 'World Trade Center cough'.

:: Edward Teller, considered the Father of the H-Bomb, has died at the age of 95. (Both stories from Nature Science Update.)
