First, they had to make sure the brownish-red hair really comes from a woolly mammoth. After that, they washed and bleached it and, from the sterilized hair shafts of the mammal, they obtained genetic material bearing clues about why mammoths died out and a guide for saving other near-extinct animals.

During yesterday’s repair session, the astronauts had a bit
of trouble with their activity. Astronaut Heidemarie Stefanyshyn-Piper lost her
grip on the tool bag used to clean the space station’s damaged rotary joint.
While working on the cranky joint, she noticed that one of
the two grease guns exploded, covering her gloves and her camera with the
substance. She began cleaning and for a few seconds lost track of the tool bag
which began floating away and reached the back of the station. Aside from the
