Today's round-up of science stories. Links are normally to press releases on EurekAlert (at the bottom end I may also add a couple of newspaper stories). I include quotes from the summary (using quotation marks) in cases where the title alone doesn't reveal what the story is about.
(Categories are still evolving. Don't really want to put stuff in boxes, but have to have some kind of structure here.)

Elephants take to the road for reliable resources
"Landscapes can change from day-to-day and year-to-year, and many animals will move about according to resource availability. But do they remember past resource conditions? Just how important is memory and spatial cognition when seeking to understand wildlife movement? Researchers in Etosha National Park, Namibia, examined this question through African elephants."
Collared African elephants like this one near a water source helped supply movement data for the study.

Illuminating women's role in the creation of medieval manuscripts
"An international team of researchers led by the Max Planck Institute for the Science of Human History and the University of York have revealed direct evidence of medieval women's involvement in the production of illuminated manuscripts. Lapis lazuli in the dental calculus of a woman buried at a 12th-century German monastery suggests that she created richly illustrated religious texts."
