As an Australian male, I need clarification of the language used in this article.
Do you mean "mate", as in someone you go boozing with, or in fact just this minute met (as in "Maaaate!")?
Or do you mean the bit of fluff you picked up during said boozing session, and intend on taking home with you?
These are important distinctions for us Antipodeans.

"Just why the mantis shrimp needs such a rarefied level of vision is unclear, although researchers suspect it is to do with food and sex."
Well Duh, Most things we do in life is for food and sex. Thats why I eat well and go to an Eye doctor.

i dunno, but at a guess, maybe the increased sensativity to smaller wavelengths may increase bit density and read/write speed? and maybe the polarisation may facilitate multilayer discs without needing a focus mechanisum, so no "layer change" waitstate, and more layers?

the above is a rough guess but probably wrong, but the only things to make a "super DVD" would be a boost in data capacity and speed?
or maybe they are fitting 50GB on those 8cm discs, instead of those massive 12cm jobs?

why are we bothering with removable media at all these days?

hey you kids, get off my lawn?

Interesting little article. But the title says something about "super DVD". What is so super about?
Mentioning how "superior" the eyes of a shrimp is nice and all. But you are leaving out how it can be significant for DVD's.
