Monday's Molecule #106: Winners

 
UPDATE: The machine is a mass spectrometer and the technique illustrated is matrix-assisted desorption ionization (MALDI) coupled to time-of-flight (TOF) measurement (MADLI-TOF).

The first person to get it right was David Schuller of Cornell University. The first undergraduate from the Toronto area was Nova Syed of the University of Toronto.



This is the second week in a row that Monday's molecule has been on a Tuesday. Sorry for the delay. I promise to get back on schedule next week.

The observant among you might have noticed that this "Monday's" molecule is not a molecule. It's my version of a machine. You have to identify what kind of a machine this is and what it does.

There are two Nobel Laureates who get credit for developing the technique shown here. One of them is responsible for the specific technique and the other for a similar variant. Name the two Nobel Lauretes.

The first person to identify the machine/technique and the Nobel Laureates wins a free lunch at the Faculty Club. Previous winners are ineligible for one month from the time they first collected the prize.

There are six ineligible candidates for this week's reward: Bill Chaney of the University of Nebraska, Maria Altshuler of the university of Toronto, Ramon, address unknown, Jason Oakley of the University of Toronto, John Bothwell from the Marine Biological Association of the UK, in Plymouth (UK), and Wesley Butt of the University of Toronto

Bill and John have offered to donate their free lunch to a deserving undergraduate so the next two undergraduates to win and collect a free lunch can also invite a friend. Since undergraduates from the Toronto region are doing better in this contest, I'm going to continue to award an additional free lunch to the first undergraduate student who can accept a free lunch. Please indicate in your email message whether you are an undergraduate and whether you came make it for your free lunch (with a friend).

THEME:

Nobel Laureates
Send your guess to Sandwalk (sandwalk (at) bioinfo.med.utoronto.ca) and I'll pick the first email message that correctly identifies the molecule and names the Nobel Laureate(s). Note that I'm not going to repeat Nobel Laureate(s) so you might want to check the list of previous Sandwalk postings by clicking on the link in the theme box.

Correct responses will be posted tomorrow. I reserve the right to select multiple winners if several people get it right.
