Follow the herd! WASHINGTON (Reuters) – The World Health Organization prepared to raise the pandemic threat level from swine flu to phase 5 on Wednesday as the virus spread and killed the first person outside Mexico , a toddler in Texas. "Things are moving fast," a WHO? source told Reuters. Nearly a week after the H1N1 virus, or swine flu, first emerged in California and Texas and was found to have caused deaths in Mexico, Spain reported the first case in Europe of swine flu in a person who had not been to Mexico, illustrating the danger of person-to-person transmission. Phase 5 is the WHO's second highest level of warning that a pandemic, or global outbreak of a serious new illness, is imminent. (its over people, end of world) "It is clear that the virus is spreading and we don't see evidence of it slowing down at this point," Dr. Keiji Fukuda, WHO acting assistant director-gener...

Scientists say an understanding of how the Twin Towers collapsed will help them develop the materials needed to build fusion reactors. New research shows how steel will fail at high temperatures because of the magnetic properties of the metal. The New York buildings fell when their steel backbones lost strength in the fires that followed the plane impacts. Dr Sergei Dudarev told the British Association Science Festival that improved steels were now being sought. The principal scientist at the United Kingdom Atomic Energy Authority (UKAEA) said one of the first applications for these better performing metals would be in the wall linings of fusion reactors where temperatures would be in a similar range to those experienced in the Twin Towers' fires. 'Not melting' The key advance is the understanding that, at high temperatures, tiny irregularities in a steel's structure can disrupt its internal magnetic fields, making the rigid metal soft. "Steels melt at about 1,150C...
