It has been the subject of movies, books, scientific discussion, and even music for longer than living memory. But has there ever been life on Mars? If so, where did it thrive? A new theory says it could have existed in vast underground lakes below the surface.
Study into toxic plants could lead to new treatments for human diseases
Many plants use toxins as a defense against being eaten. But why do these toxins not harm the plants themselves? Scientists at the Max Planck Institute for Chemical Ecology and the University of Münster have investigated the mechanisms involved in defensive toxins in plants, and their findings may lead to new treatments for human diseases.
