A taste of the lively discussion on working 24/7 (Nature 477, 5, 20–22 and 27–28; 2011).

Kausik Datta says:

Hard work is essential, but most major scientific discoveries are arrived at by serendipity, the appreciation of which requires creativity and a thinking, enlightened mind. A slave-driving mentorship that encourages drone-like devotion to work and assembly-line productivity will only result in early burn out and the loss of love for science.

Jessica Mark Welch says:

Science demands hard work, but to sacrifice your health and your family life, so that while nominally spending time with your kids you are on the phone with your lab? How unreconstructed. I do not want a world where only people who can live that way can be scientists.

Burkhard Haefner says:

All of us need time to relax and think or even to dream — to let the soul dangle, as we say in German. We all know the story of Isaac Newton wasting away his time, or so it seemed, lying under an apple tree.

Dean Griffiths says:

Rarely do insights occur after 14 hours of picking colonies. While it may be great for a PI [principal investigator] to publish lots of mediocre papers, students and postdocs require big papers to become established — and constantly working insane hours is unlikely to achieve this. Plus there really are times with your family that you can never get back. Is it worth missing them to do another PCR?

Maya Capelson says:

An average life scientist in the lab, grad student or postdoc, working 50–60 hours per week, will probably produce at least one paper in 4–5 years. Twenty-seven people working over 100 hours a week [in the lab profiled] produce just 29 papers in 5–6 years. So pretty much the same productivity as a scientist working for only half that time.

Chris Wood says:

I respect Alfredo Quiñones-Hinojosa for his honesty and the fact that he screens out his applicants to ensure they fully realize what they are getting into. And if they cannot stay the pace, he supports them in transferring somewhere more appropriate.

Srikrishna Pandey says:

Some researchers and engineers really enjoy their work, so when they have to work overtime it doesn't occur to them to resent it.

Julien Marquis says:

Some PIs may never have experienced the devastation of trashing a year's work. It is important and even pleasant to work very hard, but not always and not on anything. So PIs — if you want your crew (particularly naive PhD students) to work hard, ensure that they are pursuing a promising track.
