While some murders remain mysterious and they leave us all speculate about the forces behind such incidents, Sabeen's seems like an evident case wherein it should not be hard to trace the roots of her killers.
The father is unlikable and possibly disturbed, and Carbone leaves us to speculate on whether he played a direct or indirect part in Ian's death.
However, there was no significant induction of other key antioxidant target genes related to the Nrf2 signaling pathway, such as Nqo1, Gsta1 or Gsta2, leaving us to speculate that induction of UGT1A1 was occurring independently from a Nrf2-medicated antioxidant response in the neonatal mice, although we would not rule out the possibility that Nrf2 is not fully activated at our experimental dose.
It's worth noting, however, that the data doesn't actually tell a clear story about the 5c, and it's difficult to draw clear conclusions about how it's doing worldwide, mostly because Apple hasn't released a break-down of iPhone sales by type, which leaves us to speculate and look at a variety of analyses to figure it out.
The DNA adduct measure was poorly correlated with self-reported dietary and tobacco sources, leaving us to speculate that air pollutants may be an important source.
Indeed, in our study, adjustment for a number of measured clinical variables did not 'explain away' sex differences in HRQOL, leaving us to speculate that variables that we did not measure – like social support and depression – may be contributing to sex differences in outcome.
You could argue this is not wholly new: Ibsen's A Doll's House leaves us free to speculate on Nora's future, just as Chekhov's Three Sisters does not exactly settle its heroines' fate.
Technorati releases very little information to the public about itself, leaving us to mostly speculate on their financial health.
It could be these or any other political or personal motives, but the fact that the Times granted anonymity leaves us only to speculate.
The company has never dislcosed financings before, leaving us and others to speculate based on the occasional publicly filed document to piece it together.
However, it should be noted that the lack of a modern analogue an endothermic herbivore without adaptations to mastication or to grinding in a gizzard, both of which are intake-limiting factors leaves us speculating whether sauropods and other herbivorous dinosaurs with similar characteristics could have achieved higher food intake rates than extrapolated from mammalian herbivores.
