• Resumen

  • This article presents scientific news briefs. The U.S. National Aeronautics & Space Administration (NASA) has come up with a way to test the effects of space radiation on astronauts and their findings may clear the way for a man to travel to Mars. Researchers say that the risks of smoking persist after quitting due to a change in some genes. A study into the effects of climate change showed that grasses exposed to high levels of carbon dioxide turned into a rise of woody shrubs.
