Paulo Artaxo, professor, Institute of Physics, University of So Paulo, has won the 2007 TWAS Prize for earth sciences for his outstanding contributions to our understanding of the impact that aerosol particles, emitted during biomass burning, have on cloud formation and radiation balance in the Amazon basin. He also conducted the first studies examining how natural biogenic aerosol particles help maintain the biochemistry of Amazonian ecosystems by affecting cloud condensation and, consequently, precipitation and climate. In addition, he has undertaken in-depth studies of urban air pollution in So Paulo, again paying special attention to the source and impact of aerosol particles. Artaxo has served as a member of the Intergovernmental Panel on Climate Change (IPCC) Working Group 1. The IPCC shared the 2007 Nobel Peace Prize with Al Gore for their combined efforts in increasing public understanding and awareness of climate change.
Chih-Kung Lee, professor, Institute of Applied Mechanics, National Taiwan University, Taipei, has won the 2007 TWAS Prize in the engineering sciences for his fundamental contributions to increasing our understanding of the role that interdisciplinary systems play in such fields as optics, nano-biomechanics and plasmonics. His inventions of model sensors and piezoelectric transformers, for example, helped open a new research line in the field of smart structures. IBM has recognized his research and insights, which have led to significant advances in storage devices for magnetic disks and laser en
