McKay et al., Science, 273:924-30, 1996).
But alien microfossils aren't the only news in microscopy. Innovations in technology and technique mean bigger deals can be made out of ever smaller things. Several dozen microscopy specialists responded to E-mail and phone queries from The Scientist with opinions about the most notable new technologies.
"One test of all the exciting things out there is to make yourself a wish list and then go to the floor of our trade show, which is...
