The spacecraft that have orbited around Mars and landed on its surface have shown us (via images and data) that there is no liquid water on the surface of Mars. However, these satellite images have also revealed to us features that appear to have been created or carved out by flowing water. In fact, scientists feel...

Conditions on other planets are unlikely to be within the same ranges as that experienced by Earth. However, a degree of variance from ‘ideal’ ranges may be tolerable for a small number of organisms known as extremophiles. This investigation looks at the effects of subjecting a living organism (yeast) to some...
