Washington, April 23 : A new research has revealed that plants absorb more carbon dioxide (CO2) under polluted skies than in a cleaner atmosphere.

The research team included scientists from the Centre for Ecology and Hydrology, the Met Office Hadley Centre, ETH Zurich and the University of Exeter.

According to lead author Dr Lina Mercado, from the Centre for Ecology and Hydrology, “Surprisingly, the effects of atmospheric pollution seem to have enhanced global plant productivity by as much as a quarter from 1960 to 1999.”

Washington, April 23 : A team of British scientists has created chemicals that have the potential to kill the most deadly malaria-causing parasite, Plasmodium falciparum - including those resistant to existing drugs.

Researchers at the University of Leeds say that the compounds work by preventing the enzyme dihydroorotate dehydrogenase (DHODH) - essential to the growth of the parasite - from working, which results in its death.

Taipei- Exiled Chinese dissidents will launch a series of campaigns to demand China to apologize for the 1989 massacre of protestors on Beijing's Tiananmen Square, a Taiwan-based Chinese dissident said Thursday.
