From the animal world this week, giraffes with a heavy heart, chirpy pandas, warring baboons and wary tadpoles. After impaling myself on some cactus spines recently ("embedded journalism" ?) I have a new-found respect for plant engineering. It doesn't stop with the design of barbs and thorns though, they use aerodynamics and fluid mechanics too: vine gliders and vein flowerers.
We've all heard there might be water on Mars, but cows ? Well whatever is out there, it is certainly spewing out a lot of methane. How now, red planet ?
