I found this spider busily prepping her lunch in my backyard this morning. After a 3-minute search on www.whatsthatbug.com, I've decided it's a green lynx spider. Never seen one before!
David Kaplan at Tufts and his colleagues are using genes for spider silk protein and genes for the protein that aquatic diatoms use to make their silica exoskeleton. When the genes are inserted into bacteria, their products combine to make a strong AND stiff molecule that could be used to guide replacement bone growth.
