WASHINGTON – Stick a shovel in the ground and scoop. That’s about how deep scientists need to go in order to find evidence for ancient life on Mars, if there is any to be found, a new study suggests.

To model bacterial life, Thornburg and his colleagues turned to one of its simplest examples: a bacterial cell with a ...

A team of scientists just discovered the longest organic molecules yet seen on Mars, the fourth planet from the Sun and and a tantalizing venue for humankind’s search for life beyond Earth. Mars today ...
