Daddy Short Legs and Chemical Violins

Scientists have created "daddy shortlegs," a stunted version of the common household pest daddy longlegs, by suppressing the genes behind the arachnid's famously elongated limbs. Anthony and Jeff ask why - and how - and are surprised by the answers. Then, new research has confirmed that renowned violin maker Antonio Stradivari and others treated their instruments with various chemicals that produced their unique sound. Jeff and Anthony discuss whether this diminishes or enhances the famous artistry at work.
