Under the microscope this week, the science of forensics. We find out how scientists have exploded the myth about old aged whales thanks to a piece of shrapnel, about a new rice-based vaccine for cholera, and 'whey' to go, how scientists have made edible food wrappers from milk. We investigate what your diet does to your hair, how science can finger forgers and flush out bodies from bogs, and why the key to identifying a torso that washed up in the Thames was rooted in plant science. Plus, in Kitchen Science, we arm Ben with a rifle to find out how fat you'd have to be to stop a speeding bullet with your belly...

There are many possible reasons, but it may be that your nervous system goes into overdrive when you’re nervous. This causes your sympathetic nervous system, the flight or flight mechanism, to kick in. This can cause an increase in blood pressure, which then inspires your kidneys to produce more urine, to try to reduce the volume of blood.

A giant bowhead whale caught off northern Alaska recently had a surprise in store for the fisherman who landed it – embedded in its flesh was a piece of a "bomb lance" used by whalers back in the 1880s. And because the weapon was patented it was easy to date, confirming claims that w...
