Starving honeybees lose self-control

Starving honeybees lose self-control.

Impulsivity, the widespread preference for a smaller and more immediate reward over a larger and more delayed reward, is known to vary across species, and the metabolic and social hypotheses present contrasting explanations for this variation. However, this presents a paradox for an animal such as the honeybee, which is highly social, yet has a high metabolic rate. We test between these two com...

Self-control in honeybees.

Self-control means choosing a large delayed reward over a small immediate reward; impulsiveness is its opposite. The metabolic hypothesis states that the amount of self-control across species correlates negatively with metabolic rate (Tobin & Logue, 1994). Foraging honeybees have high metabolic rates; the metabolic hypothesis would predict little self-control in bees. But foraging bees work for...

Essay " What is the purpose of publications?…[The] purpose of data is to support, directly or indirectly, the marketing of our product. " [1] There are many reports of medical journal articles being researched and written by or on behalf of pharmaceutical companies, and then published under the name of academics who had played little role earlier in the research and writing process [2–14].

Hyperhomocysteinemia: a million ways to lose control.

Elevated plasma levels of the amino acid homocysteine increase the risk for atherosclerosis, stroke, myocardial infarction, and possibly Alzheimer’s disease. In relation to vascular biology, many studies suggest that endothelial dysfunction contributes to the complex changes that occur within the vessel wall during hyperhomocysteinemia (HHCy). The underlying molecular mechanisms that are activa...
