Sidney W. Fox

Born 24 Mar 1912; died 10 Aug 1998 at age 86.Sidney Walter Fox was an American biochemist who was interested in the biological origin of life, rather than tracing a strictly biochemical path. He gave the name proteinoid to the protein-like polymer that results from a mixture of amino acids subjected to such considerable heating as would be present during the volcanic primordial earth. Fox observed that when proteinoids or "thermal proteins," are placed in water, they self-organize into microspheres or protocells, possible precursors of the contemporary living cell. Fox argued that RNA or DNA need not date back to the origin of life, and he showed that proteinoid microspheres exhibit growth, metabolism, reproduction (by budding), and responsiveness to stimuli - all properties of life - though without a genetic system.

The supervisor for the Union O...

The supervisor for the Union Of Road Construction Workers called the meeting to order.
"Men -- we've agreed on a new deal with the state. We'll no longer have to work four days a week!"
"HOORAY!!!" the crowd cheered.
"We'll quit work at 4PM and not 5PM!"
"HOORAY!!!" the crowd roared.
"We don't have to be in until 11AM instead of 10AM!"
"HOORAY!!!" the crowd thundered.
"And now, even though 99% of the roads in the country are blocked by orange barrels, we'll only have to work on Wednesdays!!"
Silence.
A voice from the back of the room asks, "You mean, EVERY Wednesday?"
