Laboratory science has its usual pitfalls, and now add these: low temperature and high wind, reagents that never made it to Antarctica, unpredictable weather conditions that delay or cut short trips to your test site because it's dangerous to fly a helicopter in a snowstorm, Weddell seals that won't let you fish in your fishing hole, the unavoidable distraction presented by a troop of curious penguins, and... well, you get the picture.

Working out the functions of these microbial genes is a big challenge because many of the microbes that live within us are extremely reluctant to grow when cultured under laboratory conditions.

The effects of disrupting the «silent» genes revealed in these studies may be masked by the activity of related genes, or because their mutations produce defects that are not readily apparent in casual observation under normal laboratory conditions.

Why do we set aside our usual experience as delusive in contrast with the exceptional experience of the laboratory — why do we decide that an event which has seemed to happen can not really have happened, because under the given conditions no adequate cause of it could have been operative — if the relation of cause and effect is itself merely a succession of seemings, repeated so often as to leave behind it a lively expectation of its recurrence?

Because symptoms of dog flu are the same as for a common condition called kennel cough, lab tests are needed to confirm the diagnosis, said William Fortney, director for small animal outreach at the Kansas State Diagnostic Laboratory.

Largely because of these mechanisms, most marine phytoplankton tested in single - species laboratory studies and field population experiments show little or no change in photosynthetic rates when grown under high pCO2 conditions equivalent to ∼ 760 μatm (Tortell et al. 1997, Hein & Sand - Jensen 1997, Burkhardt et al. 2001, Tortell & Morell 2002, Rost et al. 2003, Beardall & Raven 2004, Giordano et al. 2005, Martin & Tortell 2006).

But, I mean, I need to finish the point, because there is uncertainty, so — in laboratory conditions, there's no question that neonicotinoids affect bee behaviour, they affect colony formation.

The debate is not how gases behave in isolation in laboratory conditions but rather how the atmospheric system behaves as a whole with all its complexity and nuances, and it is because of this that many are skeptical as to whether in reality there is any significant «greenhouse» effect.
